seis k Soe es ets te EME Sylvan jowers Obey our summons; from their deepest dells The Dryads come, and throw their garlands wild And odorous branches at our feet; the Nymphs That press with nimble step the mountain-thyme And purple heath-flower come not empty-handed, But scatter round ten thousand forms minute Of velvet moss or lichen, torn from roek Or rifted oak or cavern deep: the Naiads too Quit their loved native stream, from whose smooth face They crop the lily, and each sedge and rush That drinks the rippling tide: the frozen poles, Where peril waits the bold adventurer’s tread, The burning sands of Borneo and Cayenne, All, all to us unlock their secret stores And pay their cheerful tribute.

I.—A Revision of the Wasps of the Genus Tachytes inhabiting the Ithiopian Region. By Row ann E. Turner, F.Z.S.,
F.E.S.
Tue following notes on the Ethiopian species of Tachytes are based on the collection in the British Museum, which is rich in species from Nyasaland and Uganda, but poor in species from West Africa and the dry regions of South Africa. The species run very close, and are most easily distinguished by the distance between the eyes on the vertex, the sculpture of the vertex, the shape of the pygidial area in the female, and of the seventh tergite and eighth sternite in the male, by the colour and distribution of the pubescence, the colour of the legs, and by the number of spines on the basal joint of the fore tarsus. In some of the larger females the sculpture of the second and third sternites is also important. The mouth-parts might also be of considerable use, but I have not had sufficient material available to use them as extensively as I could wish; there is, however, considerable variation in the palpi, in the length of the galea, and in the form of the ligula. The details of neuration,

2 Mr. R. E. Turner on
though they have been much used in description, must be used with extreme caution in the distinction of species, being far from constant, variations being very common in the comparative length of the second and third abscisse of the radius. Comparatively few Ethiopian species of the genus have been described, and in most of the descriptions important characters—such as the apical segments of the male, the sculpture of the second and third sternites of the female, and the structure of the palpi and galea—have
not been noticed. J have not included species from Mada- gascar in this paper, the collection being very poor in species from that island. The occurrence of a species of the sub- genus Calotachytes in Madagascar is, however, interesting.
The species I have not seen are marked *.

Subgenus Holotachytes, subgen. nov.
Differs from typical Tachytes in the absence of the incision on the outer margin of the mandibles, in the striation of the dorsal surface of the median segment, and also in the longer and more rectangular shape of that segment.
Type of the subgenus, Tachytes dichroa, Sm.
Unlike Calotachytes this subgenus has the galea short and broadly rounded at the apex, “not rostrate ; ; and the joints of the labial palpi are short and stout.

Subgenus Calotachytes, subgen. nov.
The three following species—T. marshalli, Turn., T. mira, Kohl, and 7. admirabilis, Turn.—form a section of the genus structurally distinguished by the five-jointed maxillary and three-jointed labial palpi, other species of the geuus having six-jomted maxillary and four-jomted labial palpi. The basal joint of the labial palpi is extremely long and slender, much longer than the second joint of the flagellum, and the galea is very elongate. These two characters, however, are also present in 7. observabilis, Kohl, velox, Sm., and other related species. I look on the difference in the number of the joints in the palpi as of subgeneric importance. The known species are confined to the Ethiopian region and are of large size, and have at least the four basal dorsal seg- ments. densely covered with golden or silver pubescence. The second sternite of the female is shining, with large sparse punctures.
Type of the subgenus, Tachytes marshall, Turn.
In addition to the three Ethiopian species noticed below, T’. argyropis, Sauss., from Madagascar, also belongs to the subgenus.

? ¢. Extremely near to J. basilica, Guér., differing in the black colour of the abdomen, legs, and antenne in both sexes. The abdominal segments are very narrowly brown on the apical margin, and the gold pubescence on the abdomen is denser and deeper in colour than in T. basilica. The female has the clypeus very broadly rounded at the apex, not subtruncate as in basilica.

This is probably only a geographical race of 7. basilica, ranging over Tropical E. Africa and the southern portion of Tropical West Africa. It occurs in Nyasaland with the very similar 7. mira, Kohl, but may be distinguished at once by the very different sculpture of the second sternite of the female, and by the much greater approximation of the eyes on the vertex in the male; also by the number of joints in the palpi.

The eyes are even closer together on the vertex than in observabilis, but the anal segments are nearer to mira, though the seventh tergite is less distinctly rounded, and the eighth sternite less deeply emarginate than in that species. In the arcuate joints of the flagellum it differs from both species.

This species is nearly allied to T. hamiltoni, but has the galea much longer, fully three times as long as the scape in simulatriz, only a little more than twice as long in hamiltoni. As this character does not appear to differ in the sexes of other species, I do not think that these can be sexes of one species.

?. Very similar to 7. observabilis, but somewhat smaller, and may be distinguished at once by the clypeus, which is depressed on the apical margin, very shallowly subemarginate in the middle, with three well-defined teeth on each side. The distance between the eyes on the vertex is somewhat greater, slightly exceeding the length of the second joint of the flagellum. ‘lhe sculpture of the second ventral segment resembles that of odservabilis and basilica, but the minute punctures spread over the small triangular area in the middle of the apical margin.
6. Clypeus as in the female. Eyes separated on the vertex by a distance not quite equal to the length of the second joint of the flagellum, much further apart than in observabilis and basilica. Seventh tergite broad, rather broadly subtruncate at the apex, eighth sternite very shal- lowly emarginate at the apex, the angles not forming distinct teeth. Fourth and fifth joints of the flagellum subarcuate beneath.

The labial palpi in this species are much shorter and stouter than in others of the group, the basal joint being much shorter than the second joint of the flagellum, not longer as in odservabilis and other related species.

Very nearly related to 7’. argenteovestita, Cam., and T. bulu- wayoensis, Bisch., but differs from both in only having five spines on the basal joint of the fore tarsus, instead of six as in those species; it also differs from buluwayoensis in the colour of the pubescence on the pygidial area; and from argenteovestita in the colour of the tarsi and in details of neuration.

Differs from distanti in having six spines on the basal jomt of the fore tarsus, and in the much shorter second abscissa of the radius, also apparently in the colour of the tarsi,
I am doubtful if bulwwayoensis is really distinct from argenteovestita, the details of geuration as to the comparative length of the abscisse of the radius being very unreliable in this genus, and the other differences given by Bischoff may be due to very slight inaccuracies in Cameron’s description.

In the length of the galea this species is nearly allied to T. separabilis, from which it is separated by the smaller size, the rounded apex of the seventh tergite, and the lesser number of spines on the basal joint of the fore tarsus. In the latter case it is possible that the normal number of spines in this species may be five, as they are liable to be broken, but certainly not six as in separabilis.

This is a smaller species than separabilis or hamiltoni, aud may also be distinguished in the male sex by the seventh tergite which is rounded, not truncate, and by the more narrowly emarginate eighth sternite. The female may be distinguished from separadilis by the much more pointed pygidial area. The galea is also much shorter and broader than in either of the above-mentioned species, being no longer than the scape.

Kohl’s description is very brief, but I think I have rightly identified the species. The male from Uganda differs in having the eighth sternite very feebly emarginate, not truncate as in the specimen of the male from Yapi; the female from Yapi does not differ appreciably from that from Nyasaland.

This species is most easily distinguished by the coarse close puncturation of the vertex. Otherwise it is very near hirsutus, Sm., but in that species the sternites are finely and very closely punctured, in versatilis coarsely and more sparsely punctured.

V. Group containing a small bright-coloured cat with a delicate skull from Cayenne, and identified as F. tigrina, Schreber.
As Mr. Thomas remarks, doubt and confusion beset the determination and nomenclature of the species concerned, aud the study of the group is beset with quite unusual dif_i- culties owing to the variations in pattern and cranial characters exhibited by specimens obtained together and clearly belonging to the same species.
The main circumstance which appears to have prompted the publication of this paper by Thomas was the arrival at the British Museum of a collection of skins and skulls obtained by A. Robert at Roca Nova, in Parana.
Three of the skulls were sent to Berlin, and were compared by Dr, Matschie with the skulls of species from Rio Grande do Sul which had been named by Hensel. One of them was pronounced to be identical with the skull of the form identified by Hensel as macroura (=wiediz). It is, however, with the other two that I am now principally concerned. One of them—that of a male cat captured at an altitude of 930 to 1150 metres in Roca Nova, Parana—was declared by Matschie to be specifically inseparable from the skull of the form described by Hensel as F’. guttula.
The second skull—that of a female with precisely the same
particulars on its label—was referred by Matschie to the form.
identified by Hensel as F. guigna, Mol. But, as Thomas pointed out, this cat cannot, on the evidence, be considered as precisely identical with the species so named by Molina, because the latter came from Valdivia*, on the western side of the Andes. On the other hand, a comparison between the Parana skull, declared by Matschie to belong to F. guégna, Hensel (nec Molina), and the skull of the type of F. pardi- noides, Gray, for which no locality was known, enabled Thomas to synonymize Hensel’s species with Gray’s. This was an important addition to our knowledge.

According to Matschie and Thomas, therefore, there are two species of cats living side by side in Roca Nova, Parana —a larger (/. guttula) and a smaller (Ff. pardinoides) ,—which differ in the skull-characters mentioned by Thomas in his diagnoses of groups II. and III.
As stated above, the two skulls which formed the basis of this opinion are those of a male and female respectively. An examination of them convinces me that the differences they present are beyond doubt individual and sexual, and not specific. Nor is this conviction shaken by a comparison between the skins of the two cats. That of the male shows a bold pattern of rather large blackish spots, strong stripes on the neck, and well-defined rings at the end of the tail. Although the female is black and clearly a melanistic sport, the pattern of rings on the tail and of large spots on the sides is perceptible and does not differ appreciably from that of the male. A second male from the same locality differs a little in skull-characters and somewhat markedly in pattern from the first, the spots being differentiated into incomplete black rings partly surrounding a brownish area.
Thus it appears that groups II. and III. of Thomas’s classification are based upon a single species, Ff. pardinoides, Gray, with guttula, Hensel, and guigna, Hensel, as synonyms.
That &. pardinoides is closely related to geoffroy? does not
appear to me to be open to question. /. salinarum also comes into this category. Moreover, as Thomas has pointed out, the skull of 4’, pardinoides shows many resemblances to that of #. jaguarondi, thus serving to link the latter with F, geoffroyi. Nevertheless, although F. jaguarond: is affili- ated to the group of species, or subspecies, exemplified by if, pardinoides, guigna, salinarum, and geoffroyi, there is a wider interval between it and pardinoides than between the latter and geoffroyt. ' Now, as regards group V.: this was established for the reception of a cat from Cayenne which Thomas identified as fF, tugrina, Schreber. The skin of this animal is yellowish grey in the tint of the ground-colour and decidedly richer in tone than skins of F. geoffroyt, salinarum, and pardinoides. On each side of the body there are about five longitudinal rows of tolerably large, mostly imperfectly ocelliform spots. On the neck there are four rather narrow stripes, of which the two external pass forwards to the eyes, the median stopping short between the ears. The tail is long and boldly patterned to the end, and the hairs of the neck are not reversed.
Of the skull only the facial pait is preserved. It is poorly developed from the muscular point of view, but the special

points to be noticed about it are:—(1) the postorbital pro- cesses of the frontal are short and spiniform; (2) the maxilla is antero-posteriorly expanded above and the plane of the anterior nares is nearly upright; (3) there is a distinct although small thickening on the malar by the preorbital foramen ; (4) the lower carnassial has a long heel. This combination of cranial characters, coupled with the backward direction of the hairs on the neck, indicates, in my opinion, affiliation between this species and forms related to /. pardi- noides and dissociates it from the group represented by Lf. wiedit (macroura). The interest of this view lies in the circumstance that F’. wiedi?, until the publication of Thomas’s paper, was always regarded as specifically identical with fF. tigrina, the latter name standing for the species. Since [ can discover no valid reason for dissenting from Thomas’s determination of this cat as F. tigrina, Schreb., but, on the contrary, much that is in its favour *, it will be expedient, I think, to adopt his proposal, and regard the specimen in the Museum as embodying the characters of F. tigrina, thus re- leasing wedi from the synonymy of that species.
Thus groups IL., II., 1V., and V. of Thomas’s arrange- ment may be fused into one, and the resulting assemblage may be amplified by the inclusion of /. jaguarondi, with its colour-mutation eyra, an unspotted species with which Thomas did not deal.
I have recently shown (Ann. & Mag. Nat. Hist. (8) xix. pp. 129-132, 1917) that F. wiedi differs trom J. geoffroyt, sali- narum, and jaguarondi in the structure of the feet, and that fF, pardalis resembles F. wedi in that particular. In F’. par- dalis also the hair of the nape is always reversed in direction, as is usually, at all events, the case in /. wiedii. As living animals these two species are often very difficult to distin- guish except by size and the length of the tail. In my opinion they are too closely related to be placed in different groups, despite the differences in the skulls,
Finally, there are the two species, or subspecies, known as F’. colocolo t+ and F. pajeros, which, as I have recently sliown
(Ann. & Mag. Nat. Hist. (8) xviii. p. 329, 1916), differ in the
* It is true that Buffon’s figure of the margay, reproduced by Schreber, suggests a cat with rather a bolder pattern, a longer tail, and spots on the middle of the forehead; but it would, I think, be hypercritical to expect complete accuracy in an antique illustration.
+t The cranial differences between these two forms described by Philippi do not exist. That author’s example of F. colocolo appears to me to have been a menagerie-reared specimen, judging from the peculiar shape of the skull.

structure of the auditory bulla from all the other Felide of America. These cats have been affiliated with the Old- World forms F. ocreata and sylvestris, but their affinities appear to me to be clearly with their compatriots probably of the F. geoffroyt group.
To sum up: the American Felid, large, small, and medium-sized, may be relegated to the following groups :—
1. Group exemplified by F. pardalis and F. wiedii.

IlIl.—The Geographical Races of Galago crassicaudatus. By OLDFIELD ‘THOMAS.
(Published by permission of the Trustees of the British Museum.)
In his ‘ Primates’ Dr. D. G. Elliot has recognized a number of species of the Galago crassicaudatus group, these species being arranged practically without regard to their geographical relationships ; 3; and an examination ‘of our specimens would seem to show that some revision of the group is necessary.
In the first place, a study of the skulls indicates that the East-African forms—hindet *, panganiensis, lastotis, badius, kikuyuensis, and agisymbanus,—which Dr. Elliot has either sandwiched between or united with the forms from Nyasa and southwards, are really distinguishable from all the latter by their smaller skulls.
There is a good deal of variation in East Africa as regards skull-size, and there are probably several valid races there, but these I have not at present material to deal with.
On the other hand, the more southern skulls—Rhodesia to Zululand—are really very uniform in size and proportions, when the changes and variations due to age and sex are properly allowed for. The frequent references in Elliot to the proportions of the muzzle are really based on characters due to sex, the large broad-rooted canines of the male

causing the muzzle in that sex to be conspicuously more developed than in the female. ‘This difference has been taken again and again for a racial character, but is really only a sexual one.
As to size, those from the north of the area—Rhodesia— average larger than the more southern ones, but the difference is not very great; while of other cranial characters there do not seem to be any at all, and the teeth are alike throughout.
Colour-characters are therefore the only means of sorting the races, and.on this account I should consider all to belong to but a single species—G. crassicaudatus—with several local subspecies.
The type-locality of crassicaudatus itself, not known at the time of description, has first to be settled, and on this [ should accept the first authoritative identification of specimens and statement of locality, which were made by Peters in 1852. He says that Geoffroy’s type-specimen “ stainmnt ohne Zweifel ebenfals aus Mossambique her,” and identifies with it his own specimens from various places, of which Quelimane is the first to be mentioned. I should therefore take that as the type-locality. :
As a consequence, Gray’s kirkii from the same place becomes an absolute synonym of crassicaudatus, and his type- specimen is a topotype of it.
With regard to the next name on the list, garnette of Ogilby, commonly assigned to ‘‘ Natal,” I find that the skull of the type—which is in the Museum, in spite of Elliot’s assertion to the contrary—is distinctly too small for any S.-African Galago at all, while it exactly agrees with two from Zanzibar Island (coll. Sir J. Kirk and C. H. B. Grant), representing G. agisymbanus, Coquerel.
As the locality of the type was nowhere recorded, and was definitely stated in the MS. Catalogue of the Zoological Society’s Museum to be “ unknown,” Zanzibar is as likely a locality as Natal, and I therefore propose to accept it for the Galago of that island. It would thus be the first of the Hi.-African series of names, and would antedate Coquerel’s agisymbanus.
The following are the four subspecies of crasstcaudatus which appear to me to be recognizable, taking them from north to south :—

Grey, but washed on crown and median dorsal area with buffy or drabby brown. ‘Tail greyish, varying towards buffy or “ cinnamon-buff”’—the tip generally lighter. Lower part of limbs brown.
Zambesia—Blantyre and Chiradzula, Soxthern Nyasa (Sir H. Johnston), Quelimane (Peters, Kirk), Gorongoza Mts. (Rudd Exploration), Melsetter (Swynnerton).
3. -G. c. umbrosus, subsp. n.
‘Darker than other races throughout. Smoky greyish brown (hair-brown) on body, a clearer grey patch behind and below ears; under surface smoky greyish, the slaty bases of the hairs more prominent than usual, and their tips duller and more drabby. Limbs brown, the wrists, upper side of fingers, hairy part of soles, and upper side of feet nearly or quite black. Tail dark greyish brown, its hairs dark at base, and its end blackish in the type, though not in the paratype. ~ Dimensions of type :—
Head and body 310 mm.; tail 390; hind foot 86;
‘ear 62.

This is a darker and more smoky-coloured race than the others, such as might come from an area with a heavier rainfall. It is less grey than crassicaudatus, less brown than the next subspecies, while its dark limbs and blackish feet are peculiar to itself. In the general darkening it is probable also that a majority of individuals will prove to have blackish tail-tips, as in the type.

Lasioceros dentilinea, sp. n. CPL: BY, ite: 'G:)
The genus Lasioceros was described by Mr. Bethune- Baker in Nov. Zool. vol. xi. p. 380 (1904), from a single specimen from the Aroa River, British New Guinea.
As the species we now describe differs in certain particulars from Baker’s diagnosis of the genus, we considered it necessary to examine the type in the Tring Museum. Mr. L. B. Prout has very kindly undertaken to do this, with the result that we have to amend the original diagnosis.
‘The eyesare glabrous. The antenne have the lower surface evenly ciliated to the tip. The femora are somewhat hairy. The hind wing has vein 8 approximating to 7 and not anastomosing.
L. dentilinea diverges from the generic structure as seen in aroa, B.-B., aud will constitute a new section of the genus. As it is in secondary sexual characters that dentilinea differs from aroa we do not feel justified in giving this a separate generic distinction. ‘The new section of Lasioceros will be constituted by the following structure seen in ¢ dentilinea.
The antennz with upper surface-smoothly scaled, lower surface without concavity, pilose or thickly ciliate, with longer hairs on the outside. Hind tibiz bearing a thick comb of hair. Underside of wings with much hairy scaling.
6 . Upperside.—Fore wing greyish ochreous, paler in the cell, with an apico-costal white suffusion which is also present on the costa at a third from base; intervening space filled in by a somewhat quadrate blackish patch from costa to vein 8, but not well-marked below costa; a curved black mark on discocellular, and below it a rounded dark spot ; a

subterminal white line, strongly dentate anteriorly, but becoming obsolete posteriorly ; veins streaked with blackish behind this line, these streaks separated from a post-discal series of dark points on the veins by a series of white dots. Hind wing fuscous with a paler basal area.
Underside paler than above; fore wing with no markings except a blackish streak on costa,
Head and palpi ochreous mixed with brown ; antennze brown, the simple ciliation of inner side as in aroa, but having nothing corresponding to the black sexual comb of aroa ; tegule blackish brown; patagia grey-brown; abdo- men grey with black anal tuft; legs grey, mixed with black- brown.
Length of fore wing 20 mm.

L. aroa is represented in the Tring Museum by the type (Aroa River), and 2 ¢ ¢ from Rook Island and Goodenough Island.
The systematic position of Lasioceros is not easy to place. We retain it in the Notodontide, in which family it was placed by Baker. Our reasons for doing so are on account of the short third joint of palpus and the fore wing having vein la running into1ld. This latter character is found in most Notodontid, but is not typical of Hypside, to which family the genus has been referred by Sir George Hampson. The palpi are not Hypsid in character, but the position of vein 5 of the fore wing and 8 of the hind wing would atford some justification for regarding it as a Hypsid. Taking the characters as a whole, we consider that the position of vein 5 of the fore wing is a divergence from the normal, just as occurs in several Geometride.
Since these considerations were penned, it has come to our notice that the importance of the position of vein 5 of the fore wing was doubted by an American worker as a result of his investigations into the structure of the basal abdominal organ.
William J. M. Forbes, in an article ‘On the Tympanum of certain Lepidoptera ”’ (‘ Psyche,’ xxii. n. 6, pp. 183-192, Dec. 1916), finds a special type of the basal abdominal organ to be characteristic of the Noétuidee and notes (p. 188) that “ Alypia and the Notodontide show interesting variants of this type,’ which in his scheme on pp. 189-90 he gives as
Heterocera from Dutch New Guinea. 65
“Type 3 (parapleural fovea): Notodontide, Noctuide, Agaristide.’” In his “Summary and Conclusions,” he observes that “A study of the base of the abdomen.... suggests: (1) The Notodontidez are better placed near the Noctuidz than near the Geometridze and Bombycide,” and on p. 189 he remarks, a propos of leaving “ the Notodontide as a solitary trifid family in a mass of Quadrifide,” that “ possibly the importance of the position of M? (vein 5) in the fore wing is less than it has been considered. Already we give little weight to itin the hind wing and in certain Hydriomenid Geometridz such as Hudule.”

V.—New Races and Aberrations of Heliconius. By J. J. Joicey, F.E.S., and W. J. Kays, F.E.S.
[Plates V. & VI.]
THE races and aberrations here described are all in the collection of Mr. J. J. Joicey at Witley. It will be noted that we have kept cydno as a species, and not treated it as a form of melpomene as Dr. Hltringham has maintained in his valuable paper in the Trans. Hunt. Soc. 1916, pp. 101-148. While we think his contention is possibly sound, we prefer for the present to keep cydno as a separate species, on account of the constant red markings on the underside. If ultimately cydno should be definitely proved to be conspecific with melpomene, one would expect this red marking on the under- side to occasionally occur in me/pomene races and forms in other geographical areas outside Colombia and adjacent portions of Venezuela. Southwards these forms are unknown ; only to the north, in Central America, are they further to be met with. ‘The two forms eratophylla and melpophylla—the one a subspecies of erato, the other a subspecies of melpomene —are of more than ordinary interest in the extraordinarily close resemblance they bear to one another, although of a complicated pattern. It is very curious to note that it is the yellow transverse band that has displaced a portion of the streaking in the erato form, but has filled up a vacant space

in the melpomene form. Thus, without the yellow band the erato form becomes erythrea as known from French Guiana and the Lower Amazon, and the melpomene form similarly becomes tyche from the same regions, Yet these two, while probably sufficiently alike on the wing, are obviously different.
Heliconius numata numata, ab. melanopors, J. & K. (Trans. Ent. Soe. 1916).
Fore wing above sienna-brown and black. Inner margin broadly black. Basal half of wing dark sienna-brown, with a large black wedge-shaped mark within the cell directed towards base. A large black discoidal patch and two smaller patches above and below vein 3 close to cell. Transverse band of the same colour as the basal area, but slightly paler. Three subapical spots also of the same colour, and an indica- tion of similar marginal dots. Hind wing above similarly coloured to fore wing. The wffole ofthe outer marginal half of wing black, forming a convex area on its upper edge. A rather small! brown spot at apex within the black area.
Hab. French Guiana, Nouveau Chantier.
This is a parallel form to melanops, but of the colouring of mavors. ‘he occurrence in French Guiana of both these forms is of great interest, as the theory at once suggests. itself that possibly arcuella (a subspecies of aristiona) and with it all the forms usually associated with aristzona are all conspecific with numata: The drawings by our friend Dr. Eltringham of the genital clasps of nwmata torms (Trans. Ent. Soc. 1916, pl. xin. figs. 4-6) and aristiona forms (id. pl. xiv. figs. 3-9) are sufficiently close to offer no difficulty to such a possibility.
Heliconius numata talboti, J. & K., subsp. n.
Fore wing above with the basal area dark ochreous. Costa black. A large round black blotch within the cell and a wedve-shaped black mark running to base. A very slender curved black streak along vein 1. A narrow, yellow, trans- verse, irregular band from within the cell to vein 2, stopping some distance short of tornus and embracing a large roundish black blotch between veins 2, 3. A black blotch above this s almost merged in the black ground-colour of the apical half of the wing. An indication of a yellow transverse band from costa beyond cell to meet the first band at vein 2. Two or three yellow subapical patches much suffused with black. A trace of a row of yellowish marginal] dots.
Hind wing above dark ochreous, with a tinge of yellowish

beyond the cell. A broad black marginal band containing ill-defined pairs of whitish streaks ; the dots.on cilia clear white. Across the centre of wing is a black macular band terminating with a yellow spot enclosed by black. Some faint yellow scaling between the black spots composing the band.

Hleliconius numata silvaniformis, J. & K., subsp. n.
Fore wing above with the basal half ochreous. A very heavy black nail-shaped blotch within the cell. Costa black. _A heavy black curved band along vein 1. A large, square, black discoidal blotch joined to the black costal stripe. Space between basal black blotch and discoidal black blotch yellow suffused with ochreous. Beyond discoidal blotch is a transverse yellow band much broken up on its outer edge. Two large black blotches between veins 2, 3 and 3, 4, and touching one another. A heavy black wedge-shaped blotch running up from outer margin touches the upper of the two black blotches at the lower angle. Apex black, with three yellow spots, the two upper ones almost contiguous.
Hind wing above ochreous, with a rather narrow black transverse band. A black marginal band almost uniting with transverse band between veins 8,4 and thence com- pletely to apex, containing two or three pairs of small yellow spots. A series of marginal yellowish-white dashes.
Hab. Lower Amazon, Para, Jan.—March, 1914 (A. Hall).
This insect strongly recalls silvana diffusa, from which it may be separated by the heavy black pointed blotch in cell, silvana having instead a small round blotch only. Dr, El- tringham has treated silvana and numata as conspecific, but we cannot follow this for the present.
Sic Heliconius ignotus, J. & K., sp. n.
Fore wing above with the basal half brownish ochreous, A large black wedge-shaped basal streak joined (or sometimes separate) to a Jarge roundish black patch. Costa black and a large black discoidal patch united with the black thorax, A rather narrow discal yellow band ending quite pointedly just beyond vein 2 close to outer margin. In the middle of this band just beyond cell between veins 3, 4 is a rather small black spot, and below vein 3 is a larger black spot.

Sometimes the yellow of the band is extended inwards into the cell and embracing the lower black spot between veins 2,3. Apex completely black.
Hind wing above brownish ochreous, with very irregular black marginal band, much the heaviest on the inner half. A transverse row of rather elongated wedge-shaped black spots, the last spot merging with the outer margin and curved up towards costa. No yellow terminal spot.
Palpi with first and second joints white below and base of antennee with white points.
Expanse 78-86 mm.

Heliconius aristiona pratti, J. & K., subsp. n.
A small dark race of H. aristiona resembling aristicna aristiona.
Fore wing above with a large discal area chestnut ochreous extending towards base along costal and median veins. A heavy black streak along inner margin, sometimes stopping halfway. A very heavy black wedge-shaped area within the cell. Discoidal black spot heavy, joined to narrow costal black stripe. A heavy black spot close to cell between veins 2,3 and a much smaller one between veins 3, 4. Chestnut- ochreous projection of discal band above vein 3 rather narrow.
Hind wing black, with a commencement of a dark chestnut- ochreous (or slightly reddish) marginal band. Inside this is a triangular patch of the same colour.
Expanse 33 mm.
Hab. N. Peru, Charape, 4000 ft. (A. #. & F. Pratt, 1912). .
It is possible this is an altitudinal race, taking the place of aristiona aristiona.
Heliconius clysonimus apicalis, ab. semirubra, J. & K., ab. n.
Fore wing above as in typical clysonimus apicalis.
Hind wing with a narrow transverse red band rather less than half the width of the normal form even at its widest between veins 2,3; thence outwardly the band is reduced and gradually merges into the black ground-colour, From vein 2 to inner margin the band is only traceable.

Heliconius aristiona indecisa, J. & K., subsp. n.
Fore wing above with the base to vein 2 brownish ochreous ; the costa black, a large black blotch pointed towards base, and a large black discoidal blotch joined to the black costa. A diffuse black curved streak along vein 1 and a small blackish suffused yellow spot at tornus. Ground-colour of apical area of wing black. Beyond the cell is a short yellow band ending at vein 4 and a long elongate yellow spot between veins 3, 4. Three apical yellow patches suffused in the interspaces with dull reddish brown.
Hind wing above brownish ochreous, with a black trans- verse toothed band and a small yellow spot close to margin just above vein 6. A black marginal band, with pairs of yellowish-white dots between the veins on the margin.
Fore wing below with three pairs of white subapical dashes lying on an ochreous narrow apical band, which is continued down the outer margin.
Hab. Upper Orinoco.
Heliconius numata superioris, ab. translata, J. & K., ab. n.
A transitional form uniting numata superioris with numata numata, ab. mavors.
Fore wing above with the basal half sienna-brown. A large black discoidal blotch extended to costa and united with an irregular black half-band from lower discocellular to outer margin. A light brown postdiscal band. Two or three yellow spots forming apical band and three submarginal yellow dots.
