Entomology From the ANTKALS AND MAGAZINE OF NATURAL HISTORY, Ser. 6. Vol. xvii., January L89G. Descriptions of new Species of Butterflies of the Genus Catasticta in the British Museum. By ARTHUR GL BUTLER, Ph.D. &c. THE following species have been in the Museum without names for many years ; and, as I find that they are unques- tionably not described, I propose to name them now. 54 Dr. A. G. Butler on new Species of Butterflies. Catasticta sinapina, sp. n. 3 . Resembles C. nimlice on the upper surface, excepting that the central ochreous band is more distinctly divided by the veins, the spots composing it on the primaries smaller ; the postmedian series consists of larger spots, and the marginal spots on the secondaries are larger ; the latter wings are more elongated at anal angle ; the under surface is quite unique in colouring, the ground-colour mustard-yellow, and the veins and markings purplish brown ; the pattern corresponds almost exactly with that on the under surface of C. susiana. Expanse of wings 56 millim. Pucartambo, Peru (Whitely). We purchased this insect in 1872, but at that time I was not in a position to decide whether or no it was undescribed j it should stand near C. susiana. Catasticta reducta, sp. n. JZuterpe colla, Hewitson (not Doubleday), in Coll. Hewits. £ . Pattern of both surfaces as in G. anaitis, but this species is much smaller and has all the markings of the upper surface ochreous, irrorated with purplish brown ; the nervures are much more broadly blackish; the secondaries have a marginal series of small white spots : the macular bands on the under surface of the primaries are clear ochreous, those towards apex being more falciform. Expanse of wings 52 millim. Ecuador (Buckley). Local form boliviana. Differs from the typical form in having all the markings of the upper surface clear ochreous, with scarcely a trace of dark irroration. Expanse of wings 51-54 millim. Bolivia. The above species is represented in Hewitson's collection by seven examples — four from Ecuador and three from Bolivia — and incorrectly identified by him as Euterpe colla. In the same drawer an example of Doubleday's species is associated with a specimen of C. zande, and wrongly iden- tified as (7. nimbice. Catasticta strigosa, sp. n. J. Form, size, and general aspect above of C, hebra Dr. A. G. Butler on new Species of Butterflies. 55 deep olive-brown, the lower third of the discoidal cell of primaries sparsely irrorated with sulphur- yellow scales, the cell surrounded by a series of longitudinal tapering rays, sulphur-yellow irrorated with brown, the pointed extremities of the first six of these rays being cut off by a stripe of the ground-colour from apical fourth of costa to external angle : secondaries sulphur-yellow, irrorated with brown, but with the nervures arid a broad external border which emits pyra- midal spurs along the nervures deep olive-brown ; three elongated clear yellow spots terminating the second to fourth internervular streaks : under surface similar to C. ctemene £ , but the yellow patch on the primaries broken up into narrow streaks by the broad brown borders to the nervures. Expanse of wings 67 millim. Pucartambo, Peru (Whitely). Catasticta stramineaj sp. n. Allied to C. eurigania from Ecuador, but the upper surface deep buff or straw-yellow, with all the veins black; three elongated spots placed obliquely on the black apical area, the middle one large, the others small : secondaries with the outer border broadly black, with a deep sinus in the radial interspace. Expanse of wings 47 millim. Hob. ? Two specimens of this species stood in Hewitson's collec- tion with two of his C. eurigania from Ecuador and two of C. notha from Bolivia, the label " eurigania " standing below the three species. Unfortunately Hewitson neglected to label the present species with its locality. M286051 ON A COLLECTION OF BUTTERFLIES OBTAINED BY MR. RICHARD CRAWSHAY N Y A S A-L A N D, BETWEEN THE MONTHS OF JANUARY AND APRIL 1895. BY ARTHUR G. BUTLER, PH.D., F.L.S., ETC. [From the PROCEEDINGS OF THE ZOOLOGICAL SOCIETY OF LONDON, January 14, 1896.] [1] 103 DR. A. G. BUTLER O^ BUTTERFLIES [Jan. 14, On a Collection of Butterflies obtained by Mr. Richard Crawshay in Nyasa-land, between the Months of January and April 1895. By ARTHUR G. BUTLER, Ph.D., F.L.S.,&c. (Plate VT.) Many of the specimens in the present consignment from Mr. Crawshay, who remains for the present at his station, Deep Bay, on the west coast of Lake ISyasa1, were obtained at con- siderable altitudes, and therefore are of special interest. The only surprising thing is that comparatively few of the species prove to be undeseribed, though some of the novelties which are in the collection are of exceptional interest, such as a Neptis represent- ing a new section in the genus, a pure white species of Hyreus, a Myloihris which marvellously resembles Phrissura lasti, and a very beautiful new species of Melittia. Nine species altogether are described as new. The novelties are, however, not the only species of interest in this collection, for it contains the rare Satyrid ApTiysonturia pigmentaria, previously unrepresented in the Museum ; a variety of Acrcea johnstoni. which we required ; the female of Acrcea vinidia, var. teneUa ; specimens of A. anacreon tending to link it to A. bomba (a seasonal form of it) ; a second example of A. periphanes (seasonal form of A. guillemei} ; examples of Alana, nyassce, proving that I was' correct in speaking of the buff form as a variety ; specimens of Catochrysops glauca, a very beautiful Lycaenid new to the Museum series ; the true female of Castalius liintza, proving my C. resplendens to be a distinct species ; specimens of Durbania Tiildtgarda, of which we previously only possessed one poor example ; Larinopoda peucetia, of which the type alone existed in the Hevvitson cabinets; examples of Uranolhavma crawshayi in both sexes ; the female of Epamera sidus, new to the collection ; both sexes of Teracolus opalescens ; the male of T. mutans, which was previously unknown ; variations of Cyclopides quadri- signatus: the female of the rare Hesperid Kedestes capenas; specimens of Padraona watsoni, linking that species to P. zeno ; and the male of Icterodes roseovittata, which was previously undeseribed. As with other collections obtained by Mr. Crawshay, most of the specimens are in good condition, and therefore easily'identified : with the exception of two or three specimens (the descriptive notes of which may have been lost when they were mounted, or may never have been written on the envelopes) all were carefully labelled with the exact locality, date of capture, a popular name 1 About 10° 50' S. lat.

This is a very variable species ; not only does it differ greatly in the width of the black border of secondaries (on which character I based my A. arcticincta), but in the size and number of the black spots on the primaries. One of our 31 examples, in addition to the basal black patch, the bar beyond the end of cell, and the apical patch, exhibits five well-defined discal black spots, all of which are absent in some specimens, it also shows a conspicuous black spot on the lower discocellular veinlet. The Lycsenida3 of the collection contain a nice series of the new genus Uranothauma and several other forms of interest. 41. AL^NA NTASSJE. Alcena nyassce, Hewitson, Ent. Month.

In the wet-season form there are all gradations between the extremes of yellow and white, whilst P. periclea is a transitional form between the latter and P. narses ; therefore, if the facts proved as regards the seasonal changes in colouring in other genera of Pieringe should be found not to be true of Huphina^ the above forms would still have to be regarded as variations of one species. From the AN.VALS AND MAGAZINE OF NATURAL HISTORY, Ser. 6, Vol. xvii., May 1896. on the Pierine Butterflies of the Genus Daptonura, with Descriptions of new Species. By A. G. BUTLER, Ph.D., Senior Assistant-Keeper, Zoological Department, British Museum. IN carefully supervising the synonymy of Daptonura I noted that the outline of the wings, the width of the outer borders, and the inner edging of the latter appeared to be constant and reliable characters; but the mere tint of the wing-surface varied from white to brimstone and from brimstone to saffron, these modifications being best illustrated by such species as D. florin da and D. isandra. In D. limnoria, Godt. (limnobia, Swains.), the secondaries of the male vary in tint from pale brimstone to canary-yellow, but the orange on the border is invariably represented by a series of saffron or orange spots. Hubner's figures (Samml. exot. Schmett. ii. pi. ccxxxii.) represent a very distinct species, for which, years ago, I proposed the name D. Hubneri, writing it upon a label and pinning it into the collection ; but if I published the correction it has never been quoted, and consequently I cannot refer to it. Hiibner's insect differs in both sexes from D. lirnnoria^ as will be at once seen by comparing Swainson's admirable illustration of the latter with the plate in the ' Sammlung.' Daptonura Hiibneri. <$ . Decidedly smaller than D. limnoria, the black apical border narrower, with regularly dentate-sinuate inner edge ; the secondaries bright sulphur-yellow, with broad orange outer border and linear black edging. ? . Smaller than that sex of D. limnoria, the black cunei- form bar across end of cell connected by a streak (which passes along the third median branch) with the black outer border ; the latter narrower on the costa than in the common species and gradually decreasing in width to inner margin ; the secondaries as in the male, excepting that the orange external area and black edging are wider. . pana- mensis in both sexes, excepting that it has a somewhat broader black apical border and the under surface of the primaries is white with yellow costal border. Staudinger's D. cMricana is a " self," the male citron and the female ochre-yellow ; it corresponds exactly with a pair so-named in the Hewitson collection *, which I am satisfied are conspecific with D. florinda ; whilst Hewitson's third example is gamboge-yellow, and therefore is intermediate between D. anceps ? and D. chiricana ? . As another instance of variation in ground-colour in this genus I may mention that I have no doubt of P. pedrosina being a mere form of P. palaestra , differing in having the secondaries and costa of primaries on the under surface white instead of yellow ; there is no other difference by which to separate them. My D. pedrosina , therefore, will sink as a seasonal form or a sport of D. palaestra, Hopffer. * Staudinger's " ochre-yellow ?) I should call bright orange.

ALTHOUGH the present consignment includes only one new species, it is exceptionally interesting, not only as comprising several links between described species, but on account of the important additional evidence afforded by the careful dating of the captures ; so that now it is possible, by comparing these with Mr. Crawshay's previous consignments, to prove con- clusively that several very distinct forms declared to be seasonal and conspecific occur together repeatedly in various months of the year — that, in fact, they are not confined to any particular season, and have no more evident claim to be called forms of one species than our European Vanessa c~album or V. polychloros have to be called forms of F. urticce* 1.

Lucas, and differs from the South- African butterfly in the much brighter colouring, with somewhat differently formed and much redder bands on the under surface of the secondaries : the southern species is only the wet-season form of T. argillaceus, and is T. vesta of Trimen (nee Lucas) ; the latter, on the under surface, is much nearer to T. auriyineus, whereas T. argillaceus is certainly the southern representative of T. mutans. 90.

Expanse of wings 51 millim. Bangara, W. coast of Lake Nyasa, August 18th, 1895. "If once missed, is exceedingly difficult to take " (li. 0.). The arrival of this example is particularly interesting to me, for it shows that my belief in the local constancy of some of the named forms of the T. eris group is, so far, borne out, the seasonal forms of this Eastern and Central African type being both easily separable from the more southern examples. The type of T. eris was obtained at Ambukohl, in Lower Nubia, and is probably the true male of my T. abyssinicus, of which we only possess females : the figure agrees most closely with a male (wet-season form) received from Kilima-njaro, the orange apical spots on the primaries being short, the outer edge of the upper portion of the white area, beyond the cell, less oblique than in the southern forms, or than in T. opalescens, and the black costal belt of the secondaries extending on the disc to below the second sub- costal branch ; it, however, differs in having a small white spot near centre of outer margin of primaries, a character which may be variable. The southern forms are certainly not typical T. eris ; nor can T. johnstoni be correctly called the dry-season form of the Natal examples presented to us by Mr. E. C. Buxton, inasmuch as the latter have the under surface of the wings pink, and must there- fore themselves be the dry-season form of Mr. Trimen's T. eris (of which he says : " Underside — Whitish or yellowish-white") and identical with his variety A. If, then, certain Lepidopterists prefer to regard the representative forms of T. eris as mere local phases of one species, the fact that each of them has its dry- and wet-season forms distinct from the others gives them at least a claim to be regarded as subspecies and to retain distinctive names. 92.

The female contained "pale yellow ova"; she was somewhat worn, having probably been long on the wing. The receipt of these specimens, the male taken in the dry season and the female before the rains had fairly set in, is very interesting, as supporting the assertion that T. anacc is the wet-season form of T. regina. The entire absence of the latter from any of the collections previously received by us from British Central Africa had led me to regard this statement with considerable doubt ; but now 1 see no reason for rejecting it. 94.

Dry season, $ $ , Loangwa Valley forest, August 30th, and Ntonga, Loangwa River, Senga, Sept. 13th, 1895. After carefully studying the purple-tipped species, in relation to the question of seasonal dimorphism, I am forced to the conclusion that there is no reason for distinguishing the Eastern and Central African examples of T. phlegyas from those of the White Mle : they are slightly larger, but otherwise typical in both sexes. T. phlegyas can hardly be a dry-season form of T. imperator, because the specimen of the male recorded above (and which is fairly typical) was obtained in the middle of the rains, whilst the females were obtained near the end of the dry season : on the other hand, we have a typical male of T. imperator taken in the middle of the dry season. Furthermore, T. imperator cannot possibly be the T. ione of Godart, as assumed by my friend Trimen in his ' South African Butterflies/ Not only does the distribution of T. imperator render this highly improbable, but the description by M. Godart does not at all answer to it : — T. ione. T. imperator. 1. Black apical border divided 1. Apical area violet, narrowly obliquely by a violet band bordered with black, rounded externally. 2. A conspicuous black disco- 2. A very faintly indicated dis- cellular spot on the primaries. cocellular dot, or none at all. 3. No transverse ray on under 3. A conspicuous oblique trans- surface of secondaries. verse ray on under surface of secondaries. I do not doubt that M. Godart '« description was made from a [20] 1896.] FROM NYASA-LAND. 837 somewhat worn example of the South-African T. speciosus, to which it approaches much more closely than to any other violet- tipped Teracolus : it is the only known species which can be accurately described as having the apical black border " divided transversely and obliquely by a violet band, very brilliant, rounded externally " : it is moreover, in my opinion, wrorthy of consideration that Dr. Boisduval, who (in the Pierince especially) was apt to cut species very fine indeed, regarded the southern insect as typical T. ione, as there can be little doubt that the Doctor had examined the original type. One fact, however, must not be lost sight of: — Mr. Trimeri includes T. jalone in the synonymy of his T. ione and says that he does not consider it to be even a marked variety. Now T. jalone has a conspicuous discoi'ellular spot on the primaries, and its wet- season form has no more ray on the under surface than exists in T. speciosus ; only the apical border is conspicuously dusted with white scales, and the violet band is too close to the inner edge of the coloured apical area to be correctly spoken of as an oblique band crossing the border at apex. Mr. Triinen gives " White Nile " as the locality of my type of T. jalone, and that certainly was the locality on the specimen. Should not this have suggested to him the possibility of T. jalone being the dry-season male of T. phlegyas, rather than a hardly separable variation of T. imperator ? We certainly have one or two specimens which tend to link T. phleyyas and T. jalone ; and the two male examples taken on March 9th represent the spotted and unspotted types, although neither of them has the pink under surface with transverse ray of the typical dry-season form T. jalone. 95.

A dry-season form of this species, which cannot easily be confounded with any form of T. annce, but must stand between the latter and T. eupowpe. The dry-season form differs from the (typical) wet-season form in its superior size, the scarlet instead of orange colouring and greater width of the apical patch on the primaries, the greyer basal area and the pinky yellowish apical area of primaries and ground- colour of secondaries on the under surface ; the black terminations to the nervures are also almost obliterated : it comes nearest to T. annce, var. wallengreni, but the marginal spots are too small, the colouring below too yellow, and the scarlet above too pronounced. 96.

This is doubtless a wet-season form of some other named Teracolus and allied to T. eione : it is not at all likely to be a form of the West-African T. antigone, unless the latter can be linked by a perfect series of intergrades to T. eione, which at present I am not prepared to admit to be a fact. If T. antigone and T. eione are distinct species (as claimed in the ' South African Butterflies '), the forms from Western Africa must be kept separate from those of the South. T. phlegetonia is allied to T. eione, but does not closely agree with it in pattern, though both represent the extreme wet- season types of the country which they inhabit. In like manner, T. xanihus will probably prove to 'be a wet-season form of T. odysseus, inasmuch as both forms inhabit the White Nile, and are so much alike that their proper females were originally trans- posed ; the differences between them are similar to those which exist between T. eione and T. subfumosus, or between T. plilegetonia and T. antigone.

The type of B. sabrata was an unusually small example. A very curious female of B. thysa, with glaucous greyish apex of primaries and ground-colour to secondaries below, was obtained on the Chuona Eiver (Mwewe's), Unyika, August 26th, 1895. 103.

I wish I could agree with Dr. Holland in thinking this identical with Westwood's species ; but, as the species most nearly allied to the latter and this (A. paradisea) invariably has the sides of the abdomen ochreous, and the number of segments said by Westwood to be luteous does not correspond with the number of segments which are white in A. trimeni, I consider that, until specimens of the latter are received from the same locality as that of Westwood's type, I still have the stronger case. 114.

BUTLER ON LEPIDOPTERA [Nov. 17, This pretty species varies a good deal on both surfaces ; the black longitudinal streak on the primaries above is frequently divided longitudinally by an ochreous median vein, and trans- versely by an orange-ochreous bar just before the end of the cell ; the ochreous longitudinal stripe of the secondaries is sometimes expanded so as to leave only a narrow black costal border ; on the under surface there is occasionally a subapical decreasing series of five cream-coloured spots divided only by the nervures (which are dull orange), and the secondaries are cream-coloured, with orange-tawny veins and internal streak : intergrades between the extremes occur. 116.

Kasungu Mountain, 6200 feet alt,, March 1st; 7425 feet, March 2nd, 3rd, and 6th, Nyika. Every fresh collection brings additional evidence of the varia- bility of this species. The example obtained on March 6th has the two obliquely-placed orange spots just beyond the middle of the primaries unusually large and confluent, two small costal spots being only separated from them by the subcostal nervure. At first sight this variety might be taken for a modification of O. midas, but it is not only too dark, both in ground-colour and spots, but the inner of the two costal spots (which doubtless represents the basal orange dash in C. midas) is much too far from the base to be characteristic of that species, whilst the absence of the spot in the discoidal cell of the secondaries is characteristic of C. quadrisignatus. 118.

The damaged aberrant examples recorded under this species in my paper on Mr. Scott Elliot's collection prove to be extreme forms of the preceding species : I had thought it impossible that C. quadrisignatus could vary so much.

Broader in the wings than any other species of the genus ; the antennae broadly pectinated as in P. argentifera ; the upper radial of the primaries springing from the anterior angle of the cell, instead of from the subcostal ; general scheme of colouring recalling P. flavescens. Primaries above creamy white ; base of costa sprinkled with black and brick-red scales ; a band of red scales crossing the wing at about basal third and followed imme- diately by a band of black scales, both divided by the pale nervures; two or three ill-defined greyish and testaceous stripes across the middle of the wing ; at external two-sevenths is a broad belt almost parallel to outer margin, consisting first of a subangulated oblique series of black luuules, immediately followed by a more or less lunulate brick-red stripe, somewhat blackish in the centre, and lastly by a grey band irrorated with black and separating into vague lunules towards apex ; a few ill-defined submarginal spots of black scales : secondaries sericeous ochreous, veins dusty, becoming black at apex and on outer margin : head, collar, and centre of thorax brownish ochreous ; antennae black ; pterygodes and metathorax white, somewhat ochreous at the sides ; an oblique black bar on the front of the pterygodes ; abdomen reddish ochreous, with grey dorsal patches on each segment.

It is possible that this species may eventually be separated from Phalera as the type of a new genus, but at present there does not seem sufficient evidence of the importance of the characters which differentiate it to warrant its being thus distinguished ; the width of the wings and the antennal characters are not uniform in the genus, whilst the position of the upper radial is the same as in P. sigmata. 131.

Possibly only a dry- season form of the preceding, but little or nothing appears to be known regarding the seasonal changes in this genus : it differs from D. mysis in its gene- rally inferior size, narrower black apical border of primaries continued as a slender line to the external angle ; the yellow on the under surface of the secondaries is brighter, more restricted, and more sharply defined, and the scarlet stripe is considerably narrower, more as in D. timorensis.

I am inclined to think that D. intermedia will prove to be the dry-season form of this species and D. cruentata a nearly allied species ; on the other hand, the latter may prove to be the dry-season form and D. intermedia a form occurring at the change of the seasons. At present, however, we have no data to go upon. 76. Delias agostina. Pieris agostina, Hewitson, Exot. Butt, i., Pier. pi. i. figs. 1, 2 (1852). Darjiling, Nepal, Assam, East Pegu. Eighteen examples.

The following species is so remarkably variable that it has been split up into numerous named forms. In my opinion the Indian and Chinese forms represent modifications of one widely distributed species, the Indian variations ranging almost white to almost black, the Chinese varying less 160 Dr. A. G. Butler on the in ground-colour but with the markings more or less run together into streaks. The D. Horsfieldii form occurs both in India and China, as also does typical D. belladonna. The more or less development of yellow patches on the upper surface of the secondaries is certainly an unreliable character and not of specific value ; otherwise both D. ithiela and D. patrua would have claims to separation. I shall consider this species under its varieties. 77. Delias belladonna. Papilio belladonna, Fabricius, Ent. Syst. iii. 1, p. 1.80 (1793) ; Donovan, Nat. Rep. i. pi. xxxv. (1823). Var.

D. patrua. Chang- Yang, Central China (Leech). Only differs from the preceding variety in the reduction of the yellow patch at base of secondaries above and of all the yellow markings below. It was most inconsistent on the part of my excellent friend Mr. Leech to regard it as a distinct species, and one of these days he will doubtless admit as much. It may be supposed that my present action is also inconsistent with that formerly taken by me ; but this is not so. I have always followed the plan of regarding differently marked types, especially if they did not agree in form and had been received from different localities, as distinct species ; but whenever I have obtained series of intergrades which proved their identity, I have at once admitted the impossi- bility of keeping them separate. A very small difference in pattern may be of specific value, but a mere variation in the size of spots between two specimens taken in the same locality is most unlikely to be of importance. 78.

Butler— A Revision Ward described the wet-season form (which is largest) with almost plain yellow under surface in the male, about two black spots in the primaries and an orange costal streak to the secondaries being the only markings on that surface ; in the female the apical area of the primaries and the second- aries are buff on the under surface, the former with a sub- apical black bar representing the inner boundary of the black border of the upper surface and a discocellular black spot, the latter often with a slender interrupted angular discal stripe. T. nothus is represented by two intermediate forms, which occur in both sexes. The first has the under-surface pattern of T. MananJiari (typical), but the apex of the primaries and the secondaries are washed with rosy sienna ; the second is slightly less reddish below, but has the addition of a longitu- dinal brown stripe through the centre of the secondaries ; the female also has indications of striations on these wings. T.fiamda is a smaller form in which the striation of the under surface appears in the male, but the angular band in that sex and the subapical band in the female are obsolete. Finally, there is a true dry-season form of which we possess the male only ; it is small, the apex of primaries and the secondaries below fleshy buff, indistinctly striated, but without longitudinal streak or angular discal stripe. 26.

Eanges from the Victoria Nyanza southwards to Nyasa and eastwards to Mombasa and Bagomoyo. Both types of the species are undoubtedly sexes of the wet-season form ; the bad colouring of Staudinger's figure led Mr. Marshall to suppose that T. vulnerata was "clearly the dry-season form," but he is mistaken, for we have the latter. It is very rosy beneath, the male having the apical half and the secondaries, excepting towards apex, fleshy sienna, transversely striated with brown and more or less spotted ; there is also frequently a longitudinal dusky streak horn the base through the lower half of the discoidal cell in the secondaries. 27.

The extreme types T. auxo and keiskamma were proved by M~ansel Weale and recently by Mr. Marshall to be wet- and dry-season forms of one species ; T. topha, which is usually regarded as identical with T. keiskamma, appears to me to be an intergrade of which we possess six examples in the Museum. Of the Matabele type, which only differs in its somewhat whiter coloration, we only possess males of the wet and intermediate forms. 28. Teracolus dissociatuSj sp. n.

One of the most widely distributed and variable species of its group, ranging from Upper Egypt and the White .Nile to Abyssinia, southwards to the Albert Nyanza, the Victoria Nyanza, and Kilima-njaro, andeastwards to Mombasa. On the western side it appears to be rare, but we have one example (the type of T. syrtinus) said to be from " Senegal " and a second recorded as simply from " West Africa." In ground-colour T. evarne varies from primrose-yellow to white, the typical form being almost white with yellow diffused bordering to the orange apical area ; this is the wet-season form of the species and the most heavily marked with black. T. xanih- evarne appears to be the prevalent form of the species in * One of the supposed types of T. syrtinus referred to by Messrs. Triinen and Marshall. 454 Dr. A. G. Butler— A Revision Upper Egypt, the White Nile, and Abyssinia, and chiefly differs in it's inferior size, yellower colouring, and frequently in the larger orange patch on the primaries. T. syrtinus is an intermediate- season form which apparently ranges west- wards from Mombasa through the Sabaki valley, past Kilima- njaro and the Victoria Nyanza to Wadelai, and thence across the continent to Senegal, where it varies slightly from the normal form, the lower extremity of the orange apical patch being indistinctly bordered with blackish, so as vaguely to resemble the wet-season form of T. auxo (nobody, however, with an eye for species could calmly compare the two and for a moment regard them as identical). The males of this form never have the margin of the secondaries dotted, and on the under surface they show a slight tendency to rosy tinting. The females are altogether more lightly marked than those of typical T. evarne. T. liagore is probably little more than a rare starved albinism occurring in Egypt and on the borders of the Eed Sea ; in its weak markings it would seem to be a dry-season form, but the colouring of the under surface is that of the wet-season. I should look upon it as an inter- mediate form probably occurring just before the rains. T. citreus is the dry-season form occurring with typical T. evarne, but smaller, much more lightly marked above, and very rosy below. 30. Teracolus Phillipsi. Teracolus Phillipsi, Butler, P. Z. S. 1885, p. 772, pi. xlvii. fig. 11. Somaliland. This is a well-defined local representative of T. evarne most nearly approaching the varietal form T. liagore in character. In all its seasonal phases it is much more lightly marked and paler in colouring than T. evarne, as well as slightly smaller than in the corresponding phases of T. evarne. The ground- colouring is always white, with the pale orange apical patch very faintly tinted with yellow along the inner edge ; the marginal bordering even of the wet-season male is compara- tively weak, while the secondaries are always unspotted. The female in the wet-season has the upper surface marked almost as in the dry-season female of T. evarne, while the intermediate type, which is much smaller, has the female still less marked above and striated below with greyish olive ; the dry-season form is very small, the male without marginal markings, the female very faintly marked, but both sexes rosy and more or less striated below. of the Genus Teracolus, Swains. 455 31.

The seasonal forms of this species follow the usual rules, the wet-season forms being heavily marked above, yellowish and white with the usual markings below ; the intermediate forms are similar above, but the females show more orange in the apical black patch ; the dry-season forms are more lightly marked above and much more rosy and more strongly striated below. Of each form there are two phases, one showing a double bar on the under surface of the male secondaries, the other only showing a costal dash or dot. Of the double- barred type are, first, the wet-season form, which has received no distinctive name ; then the intermediate form, representing T. pseudevanthe ; lastly, the dry-season form, which is typical of T. eucharis. Of the costal marked type the wet-season form is again unnamed ; the intermediate form is T. aurora ; and the dry-season form T. pollens, which differs from all the other phases in showing no trace of the dusky spot on the inner edge of the orange apical patch in the male. 32.

I have seen no examples from the eastern side of India. I think that Mr. Marshall is incorrect in his assertion that it appears to range practically throughout India : our selected series of seventy-four specimens does not include one example from Eastern India. This makes it all the more probable that Mr. Marshall's inconsistent action in regarding the Ceylonese T. limbatus as a variety of T. etrida, whilst he regarded T. danae as quite distinct from the company to which he gave the name of T. eupompe, was an error. Just as T. danae differs from T. dulcis, so does T. limbatus differ from T. etrida^ whilst the latter has the additional advantage of being a purely insular form. Of the varieties of T. etrida to which I gave distinctive names, T. farrinus is the most heavily marked on the upper surface, though T. pernotatus runs it very close ; T. purus is a dwarf form of the species with rather more orange at apex than in typical T. etrida. These are all wet-season or inter- mediate forms. The dry-season phase is represented by T. casimirus and the starved form of it which I described under the name of T. bimbura. 35.

The males of this species are always heavily bordered, and sometimes so much so that the marginal spots are perfectly confluent throughout; the species seems never to attain to the size of the largest examples of T. etrida. The female on the upper surface (like its male) resembles most nearly that sex of T. etrida, var. farrinus ; but is more heavily bordered, shows scarcely a trace of the spot on the interno-median area of primaries, has brown instead of black markings on the under surface of these wings, and the discal markings on the secondaries very ill-defined.

The wet- season form of the male nearly resembles the male of typical T. etrida on the upper surface, but the female shows no trace of the interne- median spot of that species, whilst on the under surface all the discal spots arc wanting. The dry-season form is smaller, shows scarcely a trace of the black inner edging to the orange subapical patch ; the second- aries also have no marginal spots and the under surface is suffused with buff. Mr. Marshall was quite correct as to the females formerly associated by me with this insect having nothing to do with it, but he should also have discovered how closely allied it is both to T. etrida and T. lais. 37.

Ranges from Kimberley across the Orange Free State to Swaziland. The female of T. lais, the wet- (not dry-) season form, bears a vague resemblance to that of T. etrida, var. binibura, but the orange subapical bar has no inner blackish edging and there is no spot on the second median areole of primaries, the two marginal spots nearest to apex of secondaries are also confluent ; on the under surface the basal area and apical border of primaries arid the secondaries, with the exception of a discal patch towards apex, are washed with pale buff; the orange subapical curved bar of the primaries is paler than above, but the interno-median black spot is distinct. The males vary greatly in expanse, the type measuring about 34 millim., and a second example from the Godman and Salvin collection no less than 46. It approaches T. epliyia, but has more nearly the upper-surface pattern of T. biml)uray with pure white under surface (indistinctly irrorated with black scales when examined through a lens), the discocellular clots black, that of the secondaries attached to an orange spot ; the costa of these wings is also narrowly orange towards the base.

Teracolus cinctus, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. xii. p. 105 (1883). I believe that these are synonymous, although the descrip- tion of the under surface of Westwood's type does not corre- spond in every detail with that of T. cinctus, and the female is described as having a subapical yellow fascia, whilst the female of T. cinctus has the apical area black, crossed by ill-defined narrow ochreous dashes. Still I believe that variation may account for these discrepancies. One thing is certain, Westwood's insect must belong to the T. daira group, and not to the singular mixed community in which Mr. Marshall has placed it, for it undoubtedly has the orange apical patch of the male black-bordered internally. Assuming that the above synonymy is correct, the species must be inter- mediate between T. lais and T. mfumatus, and must range from the Victoria Nyanza southward to Nyasaland, and thence to Tete on the Zambesi. The intermediate form has the under surface washed with warm buff, and the dry-season form is small, with narrower black borders, the black internal streak ill-defined, and the secondaries rosy on the underside. 39. Teracolus infumatus. Teracolus infumatus, Butler, P. Z. S. 1896, p. 128, pi. vi. figs. 5, 6. Kanges from the Victoria Nyanza due south to Nyasa. This species in its wet-season form is like a large and very heavily marked form of T. pallene, to which it is undoubtedly allied ; but the intermediate-season form (of which we have a male from Lake Tanganyika) has the apical patch of orange more extended on the costa and not bordered internally by a black bar. This fact brings the species somewhat nearer to the T. daira group, in which the dry-season form has a similar character. of the Genus Teracolus, Swains. 459 40. Teracolus daira.

The latter, owing to its resemblance in the male sex to the dry-season forms of two other allied species, has been united to them and placed in. the next group of species by Mr. Marshall, the whole being united under one heading as what he elegantly calls a u job lot." 41.

Butler— A Revision taken as either a yellow variety or an intermediate type, and T. evagore ( = saxeus) is the dry-season form. Practically the whole of the forms are dry-season, but they represent the seasonal phases which occur in more variable climates. That T. evagore is the dry-season phase of T. Yerburii (and conse- quently T. Heuglini of T. Thruppi, and T. nouna of T. daira) is evident from the fact recorded (P. Z. S. 1896, p. 247) that one pupa produced from a batch of larvae bred by Capt. Nurse produced T. evagore * and all the others T. Yerburii. 44. Teracolus Emim. J . Teracolus Emini, Butler, Ann. & Mag. Nat. Hist. ser. 6, vol. vii. p. 47 (1891). Eanges from Abyssinia to the Albert Nyanza, thence southwards through Nyasaland to Delagoa Bay, whilst we have one male of the dry-season form from the Godman and Salvin collection which is said to have been obtained as far south as Graham's Town. But for the fact that the dry-season form of this species exactly resembles that of the wet-season on the upper surface, I should not have hesitated to regard it as an exaggerated development of the closely allied T. eione. The latter, how- ever, appears to be strictly confined to Southern Africa. 45. Teracolus eione. Anthocharis eione, Boisduval, Sp. Gen. Lep. i. p. 578 (1836). Teracolus galathinus, Butler, P. Z.

The wet and intermediate forms of this species are much alike on the upper surface, the latter, however, with ochra- ceous apex to primaries and entire surface of secondaries below, whilst the dry-season form is much more lightly marked above, more rosy and irrorated with brown below ; next to T. Emini it is the most heavily marked dry-season form of its group, and notwithstanding its general resemblance on the upper surface to the wet-season forms of T. phlege- tonia, I do not consider that we have enough evidence to sink it with its widely differing wet phase as a mere variation of T. phlegetonia. When it can be proved (instead of asserted without proof) that T. Emini, T. eione, T. antigone, T.xanthus, T. interruptusj and T. glycera are only variations (unin- fluenced by locality or climate) of one and the same species, I shall be one of the first to accept the position. At present I regard it as extremely improbable. * He calls it nouna, but that is a mere trifling misidentification. of the Genus Teracolus, Swains. 461 46. Teracolus ant /gone.

When I described the above forms as distinct we had no examples of the very distinct wet-season phases from the south, nor was I aware of the variability or the seasonal distinctions which occur in Teracolus; therefore when I found half a dozen or more examples which seemed to corre- spond in the possession of certain characters in both sexes, I naturally supposed that I had different species before me. The Godman and Salvin collection, which was tolerably rich in examples of this species, has enriched our series, adding eight typical examples of T. phlegetonia (wet-season) from the Cape of Good Hope, also five examples of the variety T. minans = coniger from the Cape, as well as seven examples of the dry-season variety T. delphine. With our present series I am satisfied that the above synonyms represent one tolerably variable species. I cannot, however, believe that T. antigone, the wet-season form of which always has both the base and apex of the primaries bright lemon-yellow on the under surface, and which has a much narrower internal black stripe in all its forms, is identical with T. eione or T. Emini. Typical T. antigone has no internal stripe. Of the named forms, T. phlegetonia and T. minans are wet- season phases, T. friga is intermediate, and the remainder are variations of the dry-season form. 47. Teracolus glycera. 3 .

It is possible that this may prove to be an aberrant inter- mediate-season form of T. antigone^ for, although the inner margin of the orange apical patch is unbroken by the usual black marking, the primaries have the same yellow basal suffusion, and the other characters nearly correspond with those of that species. 462 Dr. A.

This is a northern and eastern development of T. antigone, usually smaller and more weakly marked on both surfaces, especially in the wet-season form. Only the more heavily marked examples of this form show any trace of the yellow- basal suffusion on the under surface. At the same time it is possible that where the two forms meet they may interbreed, as is the case with some of the local races of birds. 49. Teracolus metagone* Teracolus metagone, Holland, Proc.

This is a wet-season or intermediate form apparently nearly approaching T. xanthus ^ var. bifasciatus ( = comptus) ; but without examining either a good figure or a typical example it would be rash to assert its identity with that species. It must, however, be borne in mind that the internal fascia on the primaries which occurs in the type specimens both of T. bifasciatus and comptus and the small transverse spot near the posterior extremity of the orange apical patch are not constant characters, but grade away to nothing even in our series. 50.

I have carefully compared the various descriptions of this species with our examples, and have utterly failed to discover any reason for keeping them separate. Three examples from the Godman and Salvin collection of the wet-season phase obtained at Kimberley (two males and one female) agree remarkably well with Mr. Marshall's description : one worn and damaged male example in our series and one in the Hewitson collection of the intermediate phase, having the apex of primaries and the secondaries beneath creamy yellowish, are somewhat larger, with the black inner bordering of the apical patch continued almost to the first median branch ; these are from Damaraland, and therefore should represent T. agoye = eosphorus-, whilst a male in the Hewitson collection of the dry-season phase from the Transvaal has all the veins finely blackened above, the apical patch intermediate in size, with only its upper half black-bordered, its outer portion irrorated with greyish lavender, the apex of primaries and the secondaries below rose-pink. But for the compara- tive rarity of T. agoye, I am certain that Mr. Marshall would not have been so inconsistent as to regard the very slight characters upon which he has separated it into three species as either likely to be constant or of the least importance. There are hardly any of the forms which he has associated under his T. evagore, T. evippe} and T. achine which do not differ more markedly from one another. He himself says of specimens which he calls T. achine : " The undersides are equally variable, ranging from the type with black neuration to a specimen in which there is no trace of black " ; and, under his T. phlegyas: "the development of the black on neuration is such an eminently unreliable character in this genus." It is perfectly well known also that the width of the black inner edging of the apical patch and the black costal streak on the secondaries are far less reliable, that the white or creamy under surface is dependent upon season, and that the discocellular dots are most inconstant. What characters then remain ? 464 Dr. A. G. Butler— A Revision 52. Teracolus niveus. Teracolus niveus, Butler, P. Z. S. 1881, p. 177, pi. xviii. fig. 1.

T. niveus represents the wet-season phase and T. candidus that of the dry-season ; the latter is less heavily marked than the type, and the orange patch, instead of filling the apex of the primaries, is represented by an oblique pale orange sub- apical band of five spots, widest in the middle and narrowest at its lowest extremity. 53.

Ranges from Zanzibar south-westwards to Nyasaland and north-westwards to the Victoria Nyanza. The seasonal variation of this species is considerably more marked than in the southern T. evenina ; T. sipylus, the of the Genus Teracolus, Swains. 465 extreme wet-season form, is usually distinctly larger than the wet-season form of T. evenina ^ and always has all the dark markings much heavier, the black marginal spots of the secondaries being connected by grey scaling into a continuous or partly confluent border and frequently preceded by a lunu- lated greyish submarginal stripe. Even Mr. Trimen, who states that the two species are inseparable, is constrained to admit that T. sipylus is " somewhat more heavily marked." T. callidia chiefly differs from the latter in having the second- aries below " brownish-white," and is probably an inter- mediate phase between the wet- and dry-season forms ; the dry- season form is T. casta, which is far more lightly marked than any South- African example of T. evenina. It is true that in Gerstaecker's figure and in our single example the male has a white under surface ; but this is often the case with individuals of the dry-season phase in other species of the genus, as, for instance, in those examples of T. dedecora (the dry-season form of T. eupompe) to which Felder gave the name of T. theopompe. Did intergrades between T. evenina and T. casta exist, one •would be bound to regard them as one species ; but the sup- posed intergrades prove to be nothing of the kind when examined with a view to seasonal variation, and the two species remain as representative localized forms. 5G.

Ranges along the West Coast of Africa from Senegambia to Accra, and thence across the continent eastwards to the Albert Nyanza. Of this species I have only seen wet and intermediate phases. If a dry-season form occurs it should be looked for in Central Africa. Both types of the species belong to the wet- season form. This may be regarded as a heavily marked development of the more widely distributed T. isaura, like which species it has the basal suffusion softly diffused, instead of almost uniform in tone with the blackish internal spot on the primaries. The wet-season form, however, is much larger than T. isaura, much more heavily bordered with black in both sexes, and with a black inner edging to the apical orange patch in the male. The intermediate form is as heavily bordered as the wet phase of T. isaura, whilst both wet and intermediate forms have the wings on the under surface 466 Dr. A. G.

Garteri • the wet-season form has the veins below tipped with black, bat it is most unusual even for the female to have them wholly blackened ; the orange apical patch on the under surface of the primaries is much smaller and more diffused, and the orange markings on the secondaries are usually weaker. Both types belong to the wet-season phase, from which the intermediate form only differs in its more feeble black bordering, and on the under- side in the less pronounced black tips to the veins ; the dry form is still more weakly marked, without any black tips to the veins in the male, the female below being suffused with buffish salmon ; it is possible that the male may sometimes have a rosy tinge below, but our examples do not show this dry- season character (which is not invariable). 58.

Although related to T. isaura^ this species appears to me to hold its own ; it is much more variable than T. isaura^ frequently showing a black internal stripe on the upper surface of the primaries and an imperfect black inner edging to the orange apical patch : the female in all its phases is much more heavily marked with blackish basal clouding and still blacker internal stripe on the primaries ; the borders and subapical bar are also blacker than is usual in T. isaura^ and the angular band on the secondaries more strongly defined ; the veins on the under surface of the wings are either black * I believe, however, that Lucas confounded with it the males of T. helle (the dry-season form of T. isaura). of the, Genus Teracolus, Swains. 467 externally (T. subvenosus), but never connected with a black marginal line as in T. isaura, or are merely dusky towards the tips (T. antevippe) : the dry-season form (T. zero) has the under surface suffused with creamy pink, and is the least heavily marked type on the upper surface. Strictly speaking, the males of this species, without any trace of the blackish internal stripe on the upper surface (typical T. antevippe), should perhaps be regarded as an intermediate phase between the wet- and dry-season forms, the wet form being represented by T. subvenosus. 59.

This may be regarded as the Southern representative of T. antevippe. It is much less heavily marked with black above, and, excepting in the male of the wet-season form (T. hero (£), is more or less densely irrorated with brown scales on the under surface ; even in this form the internal streak of the primaries and costal streak of the secondaries are incomplete. Two forms of all the phases occur, those of the wet and intermediate phases chiefly differing in size, having the under surface of the secondaries white, densely irrorated with brown ; those of the dry-season form, how- ever, are less alike ; the larger form (T. ignifer = damarensis) has the under surface of the secondaries and apex of primaries rose-pink, finely irrorated with greyish brown in the males, somewhat more sandy in colouring, with the usual transverse banding in the females, the smaller form (T. ithonus =har- monides = Haevernickii) differing from the latter in the deeper more sandy colouring of the under surface, with coarse trans- verse striation rather than irroration. The forms may be summarized as follows : — Wet-season. Intermediate. Dry. T. hero (large). Unnamed (large). T. ignifer (large). T. hippocrene. T. hyperides^ (small). I T. ithonus (small).

A representative form of T. achine apparently confined to the Eastern side of Africa from the Transvaal northward as far as Manboia. The typical (wet-season) form is generally more heavily marked above with black than in T. achine, the male even sometimes showing traces of the angular black band on the secondaries characteristic of the female ; on the under surface also, which is more creamy in tint than in T. achine, this angular band is sometimes indicated in saffron- yellow. T.fumidus (of which T. ramaquebana is the female) is merely a starved form of the subspecies. The dry-season form is less strongly marked than in that phase of T. achine, and is characterized by the usual rosy coloration on the under surface. Of our eighteen examples of this subspecies no less than sixteen were obtained in the Transvaal, nine of which were received in the Godman and Salvin collection. T. ramaquebana, curiously enough, is referred by Mr. Guy A. K. Marshall to the synonymy of his heterogeneous " T. evagore," one of the most singular combinations of dry- and wet-season forms, of species belonging to widely different sections of the genus, which have been associated together of the, Genus Teracolus, Swains. 469 since the days of Hewitson ! It only shows how utterly impossible it is to write a correct synonymic paper upon any genus without first arranging the species, having due regard at the same time not only to seasonal variation, but to geogra- phical distribution. Never since I first arranged the genus was it in such a perplexing state of chaos as during Mr. Mar- shall's few visits to it with a view to " clearing up " the synonymy. The natural result is that the " clearing up " has resulted in partial failure. 61. Teracolus g aviso, . Anthopsyche gavisa, Wallengren, Lep. Rhop. Caffr. p. 13 (1857). Teracolus hero $, Butler, P.

" T. subvenosus $ " is a typical female of T. cjavisa, but " T. hero $ " a singularly heavily marked and buff-tinted female of the intermediate phase. I should regard T. gavisa as at least subspecifically distinct from T. achine, at any rate until it has been proved by breeding to be a mere varietal development of that species. It can always be easily distinguished in all its phases. 62. Teracolus omphale. Pieris omphale, Godart, Enc. Me"th. ix. p. 122 (1819). Anthocharis theogone, Boisduval, Spec. Ge*n.

Kanges down the east coast from the Sabaki valley to the Cape. It is perhaps only an emphasized form of T. omphale, from which it chiefly differs in the greater development of black on the upper surface, even the dry-season phase having a distinctly wet-season pattern above. The female figured by Eeiche as that sex of T. exole is T. antevippe. T. acte of Felder is the true female (wet-season form), T. roxane is a female of the intermediate phase, and T. hybridus, which Mr. Marshall places as an intermediate phase of T. evippe} is the dry-season form. A. eurygone answers best to the wet- season form of T. exole, but the locality " Coast of Guinea" is rather against this identification. 64. Teracolus pyrrhopterus. Teracolus pyrrhopterus, Butler, P.

Apparently confined to the vicinity of Mount Kenya : two specimens (the types) not being ticketed with exact locality, I supposed them to be from the Sabaki valley ; the same was the case with three examples of the wet-season form, but others are labelled Thegu and Thagana. Guaso Thegu is a gorge to the west of Mount Kenya, and Thagana appears not to be far off. The wet-season form of this butterfly resembles small and lightly marked examples of T. omphale on the upper surface, but below it inclines to pink rather than cream-colour in tint, and this is especially the case with the discal stripe on the of the Genus Teracolus, Swains. 471 secondaries, whilst the subapical patch on the primaries is bright brick-red, as in the brightest examples of T. theogone (the dry-season form of T. omphale). The intermediate phase has the black banding of the upper surface still weaker, and below the subapical patch on the primaries and the discal stripe across the secondaries are sharply defined and very vivid upon a creamy ground-tint ; the fringes rosy : the (typical) dry-season form retains the black internal stripe on the primaries, which is absent in males of T. theogone, and still shows a trace of the discal stripe on the secondaries; the apex of primaries and the secondaries below are bright rosy, the former with diffused bright brick-red subapical patch, the latter with the discal stripe varying from brick-red to gravel- brown. I cannot agree at all to Mr. Marshall's arbitrary decision that this localized form is inseparable from T. omphale^ no examples of which that I have ever seen in the slightest degree resemble its dry-season phase. That T. pyrrhopterus and T. omphale had a common origin will not be disputed, but that they are now distinct I firmly believe. 65. Teracolus evippe. Papilio evippe, Linnaeus, Mus. Lud.

On the west of Africa this species ranges from Sierra Leone to Old Calabar and the Cameroon Mountains ; it reappears at the Cape, and extends up the east side of Africa as far as Natal. We have one almost typical example from the West Coast as far south as Loanda ; therefore, although the species is represented in S.W. Africa by T. ocale, the latter can hardly be regarded as more than a climatic race. On the other hand, the northern T. epigone appears to be geographi- cally separated from T. evippe, and, though nearly allied, must be regarded as a distinct species. T. pseudocale is a starved southern variety of the wet-season phase. The females of the typical wet-season T. evippe vary con- siderably in ground-tint and in the character of the apical patch ; the rarest form of the female is that which most nearly approaches the south-western race, with white ground- tint and the black apical patch of the primaries enclosing a clear orange arched band ; a second less rare form has this band 472 Revision of the Genus Teracolus, Swains. much reduced and less clear; then comes the aretkusa of Drury (which has received the names of eborea (part.), hanna, amytis, and cebrene), in which the orange has almost disap- peared from the apical patch ; the remaining varieties agree with the latter in character, but are sulphur-yellow or bright ochre-yellow in ground-colour.

Occurs along the S.W. coast in the neighbourhood of Angola, and possibly further south. The wet-season form of this race most nearly resembles T. evippe, var. pseudocale, but the female seems always to have the apical patch divided by a clear and often broad orange belt. T. suffusus was based upon an unusually dark and dwarfed example of the female. Wet, intermediate, and dry phases are all much alike on the upper surface, the dry form alone having much less black on the inner edge of the orange apical patch, giving it a totally different aspect from the southern dry phase of typical T. evippe, which has a fairly well-marked continuous black inner edging to the apical patch of the male j it is, however, possible that intergrades may occur between the two extremes. There appears to be no dry phase to T. evippe at or near Sierra Leone. 66. Teracolus epigone. Anthopsyche epigone, Felder, Reise der Nov., Lep. p. 186 (1865). Teracolus microcale, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. xviii. p. 487 (1876). Eanges from Upper Egypt to the White Nile and Abys- sinia, and occurs also near Aden. This species nearly resembles the Angolan T. ocale in all its phases, but the male always has a well-defined black inner border to the orange apical patch on the primaries, whereas the female is less prominently marked above with black than in any form of T. evippe, the spot which terminates the internal blackish streak on the primaries being wholly absent, and even the basal blackish irroration being either much restricted or wanting. At the same time, if it could be shown that T. evippe extended across Africa northwards from the West Coast, I should be inclined to regard T. epigone as a mere climatic race ; but there seems to be no evidence what- Revision of the Genus Teracolus, Swains. 473 ever upon which to base such a decision, and therefore, in spite of its affinity to the Angolan race of T. evippe, I am constrained to consider it a distinct species. The argument on which Mr. Marshall bases his synonymy of T. evippe and T. omphale, which he regards as one variable species, is based upon the confusion which existed previous to its rearrangement in the drawers of those species in the Museum collection — a confusion largely due to the incorpora- tion of accessions since the date of the first arrangement of the genus about the year 1876 or 1877. He says that in Eastern Africa T. evippe is " an intermediate seasonal form of theogone-omphale " ; but this is certainly not the case, for T. evippe is essentially, in all its characters, a wet-season phase ; nor does it appear to extend in the East further north than Natal.

From Nyasaland northward to Uganda and eastward to Mombasa. This species is certainly dimorphic in its wet and dry phases, having the apical patch on the primaries either dull ochreous or bright crimson ; it is very closely related to the southern T. Annw, but is, generally speaking, a slightly larger insect with a little less black about it, the female of the wet- ' season form clearer and more cream-tinted on the under 1 surface of the secondaries. At the same time its dimorphic character is its best one, the crimson-tipped forms (especially the males) of the two butterflies being remarkably similar in every respect. It is curious that just when Mr. Marshall was ( stating that this species had " only been received from the • basin of the Sabaki River," we were receiving a male of the i dry-season form from Nyasa, completely proving the specific identity of this species with the crimson- tipped representative jof T. Annce, four examples of which from Nyasa stand in the Hewitson series, whilst the Godman and Salvin collection j contained seven now transferred to the Museum series. An i example of the dry-season form of this variety is recorded by Mr. Marshall in a footnote as T. Annce' yet he professes to 'distinguish the two species partly by the black inner edging to the apical patch — a very unreliable character, which varies considerably in T. Annce itself. 68.

This form is the typical one, and was named by me as T. cinerascens in consequence of Pastor Wallengren's error in describing it as a Thestias ; T. Wallengreni=confusa is the dry-season form ; an inter- mediate form also occurs. 69. Teracolus Walkeri. Teracolus Walkeri, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. xiv. p. 403(1884). Elephant Bay, S.W. Africa. This very distinct butterfly was obtained by Mr. J. J. Walker, K.N., about the year 1883. This ardent collector and enthusiastic entomologist appears only to have been able to secure dry and intermediate phases of the species. T. Walkeri is, in some respects, intermediate in character between T. Annce and T. pseudacaste, the primaries of the male above somewhat resembling the wet-season form of T. Annce, but the secondaries, from their less heavily spotted border, perhaps approaching nearer to T. pseudacaste ; on the whole, however, T. Walkeri is far nearer to T. Hildebrandti and Annce than to T. pseudacaste and eupompe. 70. Teracolus pseudacaste. Teracolus pseudacaste, Butler, P. Z. S. 1876, p. 156, pi. vi. fig. 11. Teracolus phcenius, Butler, Ann. & Mag.

My three supposed species were all based upon wet-season examples, T. pseudacaste being based upon examples obtained on the White Nile probably just after the rainy season, the male lightly but the female heavily marked with black above. T. phcenius and T. miles are both typical wet-season forms, the former being more heavily marked with black on both surfaces than the latter and showing less crimson in the apical patch, the lowest spot of which is extremely small. The black veining below is sometimes very heavy, especially in females of the wet-season phase, but in the intermediate phase it almost disappears, though in this species the tips of the veins are always blackened in all the phases. Although the wet-season form of this butterfly and of the allied T. eupompe appear to occur together to the north of their range, they differ so markedly in all their phases that I of the Genus Teracolus, Swains. 497 should no more regard them as synonymous (as Mr. Marshall has done) than I should Ganoris brassier and rapce. T. pseud- acaste ranges due southwards, whereas T. eupompe appears to follow the north-eastern coast, crossing over from Somaliland to Aden. 71. Teracolus eupompe. Pontia eupouipe, King, Symb.

Anthopsyche dedecora, Felder, ibid. Ranges from the White Nile and Abyssinia south-eastwards to Somaliland, and thence across the straits to Aden. This species in all its phases can easily be distinguished from T. pseudacaste by the great reduction of all the black markings on the under surface of the wings, the subapical spots on the primaries and the discal spots crossing the secondaries being almost or wholly obliterated, whilst the red subapical stripe and the red discal spots on the under surface of the secondaries in the feir.ale are strongly emphasized. The wet-season form is T. eupompe. = anteupompe ; the inter- mediate phase is T. tJieopompe, having a dry-season upper surface, but a white under surface; whilst T. dedecora, in which the apex of primaries and the secondaries below are rosy, is the dry-season phase. The two latter undoubtedly fly together, and in Aden it is tolerably certain that all the phases emerge at the same time as mere variations, which only become seasonally fixed in a more variable climate. 72.

As 1 do not admit the identity of T. pseudacaste with T. eupompe, still less can I agree to this purely Asiatic species being the same. As a rule, it may be distinguished at a glance by its narrower and internally arched apical carmine patch, but occasionally a male with a fairly broad patch does occur, though 1 believe never a female. Another point is that T. duJcis has the base of the primaries bid •. »\v 498 Dr. A. G. Butler— A Revision more or less washed with sulphur-yellow, whereas T. eupompe and T. pseudacaste are uniformly pure white; the veins below are sometimes black-tipped, but never black throughout, and, as already hinted, the apical patch is carmine, with a faint lilac shot rather than crimson. The females vary much in the colouring of the apex in all three species. The wet-season form is represented by T. dims ( = ebore- oides] ; T. immaculatus is a variety of the same approach- ing T. eupompe in the partial obliteration of the spots on the under surface, although differing in the colouring of the apical patch and sulphur tinting at base of primaries below ; T. dulcis is a starved wet-season form, T. alberta the dry- season form, and T. subroseus a starved dry-season form or the dry form of the dwarfed T. dulcis. 73.

This species is in some respects nearer to the African T. pseudacaste than to T. dulcis , there being no sulphur- yellow at the base of the primaries on the under surface of the males and the carmine apical patch being distinctly broader than in the latter species in both sexes ; the heavy continuous black bordering fco the secondaries in the wet- season form is characteristic of T. Danae, whilst even in the males of the dry-season form it is far more heavy than in the allied species. T. Danae is the wet phase, T. sanguinalis is intermediate, and T. Taplini dry, the last-mentioned having the usual rosy under-surface coloration. 74. Teracolus fausta. Papilio fausta, Olivier, Voy. 1'Emp. Otb. Atl. pi. xxxiii. figs. 4 a, b (1801).

The true T. fausta of the Genus Teracolus, Swains. 499 lias a dry-season upperside and the male has a dry-season underside; but the underside of the female exhibits wet- season characters on the lower surface of the wings. The nearest approach to a wet-season form of T. fausta is repre- sented by a pair received from Fao, barely distinguishable from the male of my T. oriens. T. solarix of Swinhoe (and formerly of the Museum series), = T. oriens (part.), Butler, is the true wet-season form of India, and T. rosaceus the dry-season form ; but so intimately is this connected with T. faustina and fausta through the Persian examples above referred to, that it cannot be regarded as a distinct species, but can only be spoken of as the Indian development of T. faust'i ; even as a race it could only be arbitrarily separated by restricting it to Indian examples. On the other hand, Air. Marshall's action in placing the Arabian T. vi as a synonym of T. fausta shows want of care, or, perhaps, of discernment, in noting its entirely different wing-outline. 75. Teracolus vi. Teracolus vi, Swinhoe, P. Z. S. 1884, p. 437, pi. xxx. figs. 6, 7. Aden, Arabia. This species is allied to T. fausta, to which it bears a general resemblance; it, however, differs in its shorter, broader wings, with more arched outer margin, in the much yellower tint of the under surface, from which the discoceliular spots have almost wholly disappeared, whereas the discal markings, though soft and blurred, are distinctly discernible both in primaries and secondaries. T. vi is undoubtedly a dry-season form which has no other phases, and is as distinct a species from T. fausta as are T. fulvia and T. tripunctatus. 76. Teracolus falvia.

Mr. Marshall has confounded T. solaria with T. fausta and T. fulvia with T. tripunctata j but all are easily separable. T. Solaris is simply T. fulvia, being based upon Wallace's type of that species. 500 Dr. A. G. Butler— 4 Revision 77. Teracolus tripunctatus. c? . Teracolus tripuncta, Butler, P. Z.

Probably occurs over the greater part of South India and at Trincomali in Ceylon. It is readily separable, both in its wet- and dry-season forms, from T. futvia by the much blacker apical patch on the primaries enclosing three isolated spots of the ground-colour, instead of being divided by a belt of spots ; the marginal spotting of the secondaries is also much heavier than in T. falvia and the under surface of the dry-season form yellower and less rosy. We have fifteen examples in the Museum from Bombay and the Nilgiris on the west and from Ganjam and Ceylon on the east. 78. Teracolus celimene.

Appears to range from Abyssinia to Swaziland, whence we have a dry-season male obtained by Mr. Buxton. I cannot believe that Anthopsyche pholoe of Wallengren is identical with T. celimene ; the description reads like that of a female, but does not agree with the female in the Hewitson collection. We have the typical wet-season form of male T. celimene from Lake Nyasa (G. & S. coll.) ; therefore Mr. Marshall's suggestion that the western T. pholoe is the dry-season form of the eastern T. celimene (of which we already have both wet and dry forms) seems far-fetched. 79.

The range of this species, so far as at present known, is from Damaraland eastward to Lake N garni. It seems probable that Wallengren described the female and Trimen the male; the two series of red spots upon which my friend relies as disproving the female character of T. pholoe are the chief evidence in its favour, for, as Trimen himself shows, the males of this group of Teracolus have the apical patch purplish lake, violet-y tossed and intersected by a black streak, not, as Wallengren says, black, with violet-glossed red spots in two rows. The female of T. prceclarus gives an indication of such a character, but has the marginal spots also red instead of yellow. of the Genus Teracolus, Swains. .001 80. Teracolus prceclarus.

This beautiful species is evidently a link between T. pholoe and T. zoe, although the latter is in many respects more nearly related to the T. halimede group. It is probable that other species of the T. celimene type still remain to bo dis- covered. T. prczclarus appears to be a dry-season form. 81. Teracolus zoe.

Appears to be confined to North-eastern Africa, from the White Nile to Somaliland, and southward as far as Kilima- njaro. It is readily distinguishable from T. halimede by the orange patch on the primaries being restricted to below the first median branch and the outer dusky border only represented, even in the wet-season examples, by spots. The type of the species is, in my opinion, an intermediate form between the wet and dry phases. I have not yet seen what I should regard as an undoubted dry-season form, unless it be repre- sented by a small example from Mr. Druce's collection (Gr. & S. coll.) in which the orange is carried a little above the first median branch, the base somewhat glistening and white, and the apical markings weak as in typical T. leo. This specimen is without locality. 83. Teracolus halimede. Pont i a halimede, King, Synib. Phys., Ins. pi. vii. rigs. 12 15 (182!^. Ponliu acnste, id. /. c. figs. 10, 17 (1829).

If the species could be trans- ferred to a variable climate, doubtless the varieties would become strictly seasonal forms, as is the case with other species of Teracolus. Our series of this species is very fine. 84. Teracolas venosus. (51 . Idmuis venoea, Staudinger, Exot. Schmett. p. 43, pi. xxiii. (1.885) ; $ , Holland, Proc. U.S. Nat.

It would not surprise me to find that in the dry season the male had a tint of orange and that the female resembled a washed-out T. ccetestis. However, this is mere conjecture. Mr. Marshall says that T. venosus comes closest to the halimede group. I would go a step further and say that it belongs to that group, for it differs in nothing but the absence of orange colouring. 85. Teracolus heliocaustus. Teracolus heliocaustus, Butler, P. Z.

In the Grodman and Salvin collection were four examples of typical T. chrysonome (received from Mr. Druce, who purchased them from the Kaden collection); these correspond closely with Klug's figures, and are undoubtedly the wet- season form of T. arenicolens. They differ from rny supposed T. chrysonome from Somaliland in the much less defined markings upon an opaque pale sulphur ground on the under surface, and on the upper surface in the slightly more slender and sometimes imperfect blackish irregular stripe across the primaries ; the males also with the basal white area chalky, much less suffused with ash-grey, and extending to the end of the discoidal cell. 89.

Teracolus rhodesinus. Teracolus rhodesinus, Butler, P. Z. S. 1893, p. 663. Lake Mweru, Central Africa I have only seen the type of this species (a wet-season male), but it is so markedly distinct from the allied T. mutans that 1 cannot for a moment entertain the notion of its being a form of that species. It differs not only in the slender discal band across the upper surface (which is partly obliterated), but in the creamy ochreous tint of the upper surface extending inwards almost to the base of the secondaries, in the paler sulphur tint of the apex of primaries and the secondaries on the under surface, as also in the strongly defined and more parallel inner angular band across the latter wings. In some of these characters it more nearly approaches T. aurigineus. Mr. Marshall asserts that this butterfly combines the characters of T. Hanningtoni and mutans I I fail to see where T. Hanningtoni comes in. of the Genus Teracolus, Swains. 505 93. Teracolus mutans. Teracolus vesta, Trimen (not Reiche), South Afr. Butt. vol. iii. p. 160 (1889). Teracolus mutans, Butler, Ann. & Mag.

Ranges from Nyasa southwards to Natal, occurring on the Zambesi, in the Transvaal, and at Delagoa Bay. After examining twenty-nine examples of this species, including some interesting varieties recently collected by Mr. Guy A. K. Marshall, I am unable to follow that gentleman in his decision as to the identity of the southern insect with the Abyssinian T. vesta ; the latter, judging from the descrip- tions and the original illustration, is slightly larger and differs in the salmon-buff of the upper surface extending in the cell of primaries right up to the almost black basal suffusion, in the even heavier black border of the secondaries and the yellow suffusion on the interno-median area, in the less irregular and uniformly redder bands on the under surface of the secondaries, the inner and submarginal bands being also broadly and sharply denned. Most examples of T. mutans show very little blackish suffusion at the base of the wings on the upper surface ; but Mr. Marshall, who seems to be one of the most energetic and indefatigable of collectors, has sent us several unusually heavily shaded examples, in which the basal suffusion is deep bluish ash-coloured, but far from approaching the grey-blackish tint of typical T. vesta. The more southern examples of T. mutans are considerably smaller than the Abjssinian species, but the Nyasa examples sometimes run it very close in expanse of wings. T. argdlaceus is the dry-season form of the species, and we have some very pretty intermediate examples from Delagoa Bay and Nyasa. 94. Teracolus vesta. Idmais ve*ta, Reiche, in Ferr. Gal. Voy.

Both descriptions and the illustration of this species are taken from the wet-season form. Reiche's figures apparently represent a female.

Hist. ser. 5, vol. ii. p. 178 (1878). East Africa, from the Sabaki valley southwards to Masasi. The wet form alone of this species has hitherto been re- ceived. It is readily separable from T. mutans and vesta in the small size of the submarginal spots on the black external area, and in the white colour of these spots on the secondaries of the female ; from T. mutans also in the greater distinction of tint between the orange ground-colour and yellow apical and external spots on the under surface of the primaries and the deep red bands on the under surface of the secondaries, and from T. vesta in the straighter character of these bands and the slenderness of the innermost one. A female from the Sabaki valley has the ground-colour above entirely white, feebly tinted with sulphur-yellow, and the colouring below paler than usual. 96.

The wet-season forms differ from the dry in the much greater width of the outer blackish border to the primaries ; between the two seasons this border is intermediate in width. 5. Terias harina. Terias harina, Horsfield, Cat. Lep. E. I. C. p. 137 (1829) ; Hiibner, Zutr. exot. Schmett. figs. 979, 980 (1837). Eanges from N.E. India through Burma, the Mergui Archipelago and Andamans, Malacca, Java, and Borneo, eastwards to the Celebes. The name T. formosa was probably first given to Hiibner's figures of T. harina by the late Adam White, and thus appeared in a list of the species of this genus which I pub- lished (P. Z. S. 1871, p. 540) at a time when I had no perfect copy of Hiibner's work for reference. In that list, oddly enough, I transposed the sexes — the type of T. harina being a female, that of Hiibner's illustrations a male. In the Philippines a fairly distinct race occurs, of which * T. hainana has a slightly narrower border to the primaries than T. libijthea. 60 Dr. A. G. Butler on the Old- World I have seen no extreme dry type : the wet form is larger than in T. harina, the blackish outer border extending to the secondaries even in the males, where it runs from the apex to beyond the third median branch, and in the females sometimes to beyond the first branch ; the costal margin in this form is also much less arched than in T. harina : the intermediate form is normal. 6.

I have only seen the dry-season form of this Terias and therefore have not sufficient evidence on which to conclude that it is a race of T. harina ; it differs from the dry-season form of that species in the more uniform width and con- tinuous character of the blackish border to the primaries. T. Candida group. The species of this group do not appear to exhibit any appreciable seasonal characters; they also differ from the T. harina group in the fact that the females are not very variable in the same species : white is the characteristic colouring of the upper surface in all the species excepting those of the Solomon group, which have yellow females. 7.

Differs from the two preceding species in the more regular and slightly more concave inner edging of the black outer border to the wings, which runs farther back on the costa of the primaries ; in the majority of the males this border is wider than in either T. virgo or T. puella, and in the females it is invariably wider than in T. virgo : the expanse of wings varies considerably, 39 to 54 millimetres.

The wet- and dry-season forms differ considerably : in the latter the dark border to the secondaries is reduced to a series of dots terminating the nervures ; on the under surface also the apex of the primaries is often suffused with rose- colour, and two or three deep brown markings appear some- what as in the T. hecabe section of the genus. 62 Dr. A.

Desjardinsii by Mr. Marshall ; it is, however, widely distinct, the female especially differing in the typical (wet-season) form in its broad hind- wing border; both sexes also differ in their less angular wings, with far more regular arched inner edging to the border of the primaries. In the dry-season form the border of the second- aries is replaced by dots, but the markings on the under surface are as indistinct as in the wet-season form,- the apex of the primaries being very delicately tinted with rose-pink. 15. Terias Marshalli, sp. n. Terias Desjardinsii, Trimen & Marshall (not Boisduval). Wings much more angular than in the preceding species, the inner edge of the outer border of primaries irregularly sinuated, most prominently on the upper radial and two median interspaces; the outer border of the secondaries usually narrower, always distinctly so in the female and most fre- quently reduced to a marginal series of spots in that sex ; markings below better defined, but especially in the inter- mediate and dry-season forms, which show an additional irregular subapical brown dash on all the wings and a rusty flesh-coloured border to the primaries. On the upper surface the three tolerably well-defined seasonal types differ chiefly in the width of the dark outer border to the wings, that of the secondaries being reduced in the dry-season to a narrow dentated line in the male and a series of dots in the female.

The black-tipped white female figured by Mabille in Grandidier's ' Madagascar ' does not belong to this section of the genus, but is a variation of T. hapale. 1 7. Terias punctinotata. $ .

The male is bright lemon - yellow, with a black outer border to the primaries, regularly arched internally as in T. regularis ; it is different from the latter in outline, the costal margin of the primaries being longer and the apex more acute ; but for this fact and its much clearer (less deep gamboge) colour I should have concluded that it might be the dry-season form of T. regularis, that previously noted being the intermediate form. 18.

The males characterized by the presence of a patch of thickened scales between the median and submedian veins towards the base of the primaries below and a corresponding subcostal patch on upper surface of secondaries.

Eanges from the Himalayas southward to Ceylon and probably eastwards through North China, for we have it from Chusan Island and from the Philippines. The seasonal (?) forms differ less than usual : T. rama is probably the best-marked wet type, T. santana intermediate, and T. venata (of which T. pallitana is the female) the dry; but, on the other hand, it is possible that, as seems to be the case in the closely allied T. betkeseba, no differing dry form may exist, and the slight discrepancies in the pattern of the upper surface or the definition of the markings on the under surface may be partly local and have a subspecific value. The fact that we have the extremes from the Anamully Hills proves that they are not permanently separated as distinct species. Two males in the Museum from China differ in having the female pattern on the upper surface of the primaries as in T. Iceta. 22. Terias herla. Pieris herla, McLeay, King's Surv.

Mariesii is the wet-season form, T. anemone, hybrida, and connexiva intergrades, and T. mandarina the dry-season form. The transitions from wet to dry affect both surfaces simul- taneously in this species, and thus at once distinguish it from T. hecabe and T. suava, in which the upper surface varies enormously at all seasons. The wet form (T. Mariesii) differs from the parallel variety of the wet form in T. suava in the more abrupt costal termination of the apical patch on the upper surface. Our series of this species is represented by 127 selected examples. 34. Terias Hobsoni. Terias Hobsmi, Butler, P. Z. S. 1880, p. 668. S.E.

In this species the wet-season form appears to vary very little, but the intermediate and dry forms exhibit considerable variation in the width of the outer border of the primaries. T. cesiope is a dry form corresponding with the wet-season form (T. hecabe) ; in T. subdecorata the only difference of importance is in the much less angular upper inner margin to the apical portion of the outer border ; in T. blanda the inner edge of the outer border is almost or often quite regu- larly arched, and T. arcuata appears to be the same thing with an intermediate character of under surface. The follow- ing, which may prove to be a further development of the dry-season form of T. hecabe} was also described from Hainan ; but the Museum possesses only a pair, presumably of this species, from the Loo-choo and Madjico-sima Islands ; therefore, for the present, I keep it separate. 37.

This species well bears out Darwin's statement that common and widely distributed species vary most. T. suava (com- monly confounded with the broader-winged and far less variable T. hecabe of S. China) exhibits more inconstancy than any other species of TeriaSj and consequently has received numerous distinctive names. As every gradation of upper-surface pattern, from the typical broad-bordered T. suava to the narrow-bordered T. narcissus, is represented at all seasons, it would seem to a superficial observer that many species were represented by the forms of this butterfly ; when, however, it is found that these forms are not limited to locality and comprise a perfect transitional series, it becomes evident that they represent one extremely variable species. In order to facilitate their identification I shall consider these intergrades as separate varieties, beginning with the most broadly bordered typical form and ending with those ii which the border is reduced to its narrowest limit.

T. phanospila was based upon old discoloured males from Java; we have exactly similar specimens from Horsfield's collection. This is the dry-season form of the species. 40. Terias silhetana.

The character by which the late Capt. Watson proposed to distinguish T. silhetana from other species of the T. hecabe group is that it has an extra black dot near the base of the discoidal cell on the underside of the primaries. Unfor- tunately this character is not always present, though usually so in the narrow-bordered forms of the species. T. silhetana separates fairly easily into two types, the first with a broad border to the secondaries at all seasons, the second with a narrower border in the wet-season, which almost or quite disappears in the dry-season. Broad-bordered type. The wet-season form is unnamed ; the dry-season form is T. citrina—T. simulatrix =T. tecmessa (the latter being the drier and commoner variation). Narrow-bordered type.

As a fact, the cell-markings on the under surface of the species of Terias are eminently variable both in number and position, sometimes on opposite wings of the same individual. * We have a female said to have been obtained at Afghanistan over fifty years ago ; but this is probably an error.

Ranges from Northern Australia northwards to Timor Laut, Am, and New Guinea, and thence eastwards to New Ireland, appearing just to touch the Solomons ; more to the south it ranges eastwards to the Loyalty, New Hebrides, and Fiji Islands. This species exhibits a more restricted variability than T. suavcij which it doubtless replaces in Australasia ; the mode of variation is, however, similar. Regarded as a whole it is a smaller type, never so heavily bordered or suffused with blackish as typical T. suava nor so narrowly bordered as T. apicalis. The varieties with their seasonal forms are as follows : — Yar. I. The wet-season form is T. photophila, with the outer border slightly narrower in T. liebridina, the upper angle of the sinus rounded off and the border of secondaries very narrow or reduced to dots in T. inanata and aprica (the hitter is larger than T. inanata and has the margin of secondaries dotted). The intermediate form of this variety is unnamed. The dry-season form is T. maroensis—phcebuSj of which T. sulphurata and variata are narrower bordered examples, the latter small and with dotted margin to the secondaries. Var. 2. The outer border of primaries broad at apex, but narrow at external angle ; the seasonal forms are unnamed. 76 Dr. A. G. Butler on the Old- World Var. 3. The outer border of primaries much narrower throughout. The wet-season form is T. pumilaris (starved) and T. sina- pina (full-sized) ; intergrades between the two extremes are in the Museum series. The intermediate form is T. lifuana == T. laratensis (the differences very slight) and the dry form is unnamed. 52. Terias brevicostatisj sp. n. Readily distinguishable from all species of this group by the short costal margin to the primaries and the more rounded outer margin; the apical portion of the external border is consequently narrowed, just as though its outer edge had been trimmed off ; the subapical angle of this border is more obtuse than usual, the secondaries are subangulated at the end of the second median branch ; the outer border of the secondaries is well-defined, regularly sinuated internally, but varies somewhat in width and length ; the general colour of the male above is saffron-yellow and that of the female citron-yellow; the markings below are normal, but not very strongly defined in the wet and intermediate forms ; the dry form is unknown to me. Expanse of wings 41-47 millim. Semao Island, Timor (coll. Hewitson), Wetter, (probably Bourou), Batchian, Ternate, and Gilolo. The general aspect of the males is that of the T.

Ranges from Nias through Borneo eastwards to Ternate and Batchian, extending south to Amboyna and Ceram, and probably crossing New Guinea, to reappear in the Louisiade and Solomon groups. The males of this Terias seem to run very close to those of T. sulphurata, of which species I should be inclined to regard it as a variety but for the white or creamy colouring of the females. In the Solomon group this type of female seems to be abundant, whereas the yellow female of T. sulphurata seems to be extremely rare; from Amboyna again I have only seen white females. In the Solomon Islands the females Pierine Butterflies of the Genus Terias. 77 would seem to be most prevalent between the wet and dry seasons, nor have I seen a single dry-season male. T. biformis was based upon a male with dry-season upper surface and a typical wet-season female; the former has usually a very narrow outer border, and sometimes the base and edge of the inner margin are irrorated with dusky scales, so as to approach the least pronounced forms of the T. rahel group. T. lacteola and ada were both based upon females, the first white, the second creamy or with a faint tint of sulphur ; the outline of the border of the primaries and the dusky irroration of the upper surface are characters which vary much in this species. Our series of T. biformis is now represented by seventy-one examples. The names T. biformis, multifrons, and multiformis, pro- posed by the late Mr. H. Pryer for T. subfervens and T. man- darina, were given in defiance of the law of priority, and, but for the fact that they have recently been quoted by a scientific worker, I should simply have ignored them, as I should the names ignorantly given in a story-book. Not only was the name T. biformis proposed in 1887 for a butterfly which Mr. Pryer believed to have several names already, but it was given as the name of two species which Mr. Pryer believed he had bred (and which a friend of his was satisfied he had not bred) from one another. Lastly, the name T. bi- formis was given in ignorance of the fact that it had already been employed in the same genus about three years and a half previously. With regard to his T. multifrons, subsequently altered without comment to T. multiformis, Mr. Pryer believed that it included no less than ten forms, all of which he declared that he had bred from eggs laid by T. mandarina, although most of them never were seen in Japan, and one, at any rate, is a well-known West-African species. Subsequently Pryer extended the species to include what he called T. Iceta (meaning T. subfervens}, the wet and dry forms of which he probably regarded as T. Iceta and betheseba, or T. Iceta and Jcegeri, according to fancy. When it is remembered that the T. Iceta group is charac- terized by entirely different male sexual marks from the T. hecabe group, the fact that Pryer believed he had bred one from the other invalidates the whole of his breeding experi- ments, proving them to have been far more careless than the positive assertions of this collector would fain constrain us to believe them. 78 Dr. A. G. Butler on the Old- World 54. Terias indecisa, sp. n. $ . Gamboge-yellow ; the primaries having the base blackish, the costal margin very narrowly grey, the apex and a narrow external border dark brown,, insinuated internally as in T. gradiens, with a slight widening at external angle, but without a trace of the internal border characteristic of the T. rahel group ; secondaries with a dentate sinuate external border, a little broader than in T. tilaha and more diffused towards the anal angle : wings below slightly paler than above, with the characteristic markings of the T. hecabe group (wet-season) represented by brown scales and not strongly defined. Expanse of wings 45 millim. Batchian (Wallace). This seems to be a link between the T. hecabe and T. rahel groups ; its upper-surface pattern is characteristic of an inter- mediate or dry-season form, but that of the under surface proves it to be a wet-season form. This insect is so very distinct from any other described form that, although slightly discoloured with age, I am constrained to regard it as new to science. T. rahel group. The inner border of the primaries and sometimes the abdo- minal border of the secondaries more or less broadly bordered with deep brown ; in some species these and the ordinary borders are so much extended as to occupy the greater portion of the upper surface, leaving only a patch of yellow on each wing, whilst in the females even these patches are sometimes irrorated with brown. 55.

The greater size, much broader apical border of primaries, the more elongated sinus in the border on the lower median interspace, and the exten- sion of the inner border so as to impinge upon the discoidal cell at its base render it next to impossible that this can be the intermediate form of the preceding species, for we know that the change from a wet- to a dry-season character in this genus is usually accompanied by a decrease in the dark borders of the upper surface, and never by an increase in their width. When any change in size takes place, it tends towards diminution of expanse in the dry season. 58. Terias Nicevillei, sp. n. I believe this to be the T. tilaha of De Nice'ville ; it is the smallest species of the group ; it differs in pattern from T. tilaha in the slightly more regular inner oblique edging to the apical border of the primaries, the slightly narrower outer border of the male secondaries and the broader border to those of the female ; the latter sex is also much deeper in colour than in T. tilaha, being nearly as bright a yellow as the male ; the under surface is similar to that of T. tilaha.

The abdominal border of the secondaries is less strongly marked than in T. tominia. This, again, is an intermediate form in the under-surface markings. 80 Dr. A. G. Butler on the Old- World 60.

The female (of which we have both wet and intermediate forms) differs chiefly from that sex of T. tondana in the narrower and more smoky-yellow belts on the wings ; the male, however, is widely different, the yellow area on the primaries being reduced to a broad oblique belt and that of the secondaries bounded behind by the median vein. Con- sidering the constancy of the species in this group, we have at present no grounds for supposing that T. tominia alone should vary to this extraordinary extent ; therefore, in spite of the general similarity of the females and the fact that both types appear to occur in the same islands, they must, for the present at any rate, be regarded as different species. 62.

The female from the Sula Islands differs from that obtained at Macassar in having the outer half of the primaries black ; it would be interesting to see whether this difference was constant. The male would be best described as having the primaries above like those of T. sari and the secondaries like those of T. fominia.

A very broad-bordered form occurs, of which we have six examples from Samboangan and Davao, which nray possibly be distinct, as well as a pair similar to the last but with the yellow area of the primaries abbreviated.

We have seasonal types of this species ; but in the T. rahel group generally there is something undecided about the various phases of the species, which makes one doubt whether the species of this group ever exhibit well-defined seasonal forms such as exist in all the other groups of the genus ; possibly they may be in a transitional stage towards extinction, for I believe that they have not been developed by changes of tem- perature, but have simply been adapted to them, inasmuch as 82 On Pierine Butterflies of the Genus Terias. they are often all well-marked and emerge simultaneously in countries where practically no wet-season exists ; but, on the other hand, in countries where the weather is more or less moist throughout the year the dry forms are either wholly absent or are extremely rare (probably only existing as reversional sports).

THE present genus is confined to the Old World, being found throughout India and Ceylon, Burmah, Siam, China, and south-eastwards to the Celebes and Timor. Ixias in general aspect resembles certain groups of the genus TeracohiSj but is readily distinguishable by the neura- tion, the first two branches of the subcostal vein in the primaries being emitted wider apart, the upper radial emitted from the subcostal vein well beyond the end of the cell (expressed in the recently adopted phraseology this would stand as "veins 6, 7, and 8 stalked"). In the secondaries the discocellulars are much more oblique than in T<>racolus. The seasonal variation of Ixias differs somewhat from that of TeracoluSj nor is it quite consistent in its character throughout the genus. As a rule the wet form has heavy borders to the wings on the upper surface and scarcely any markings on the under surface (often only a black dot at the end of the discoidal cells and a spot at the external angle of the primaries), but in some of the species there appears to be no wet phase of marking and coloration, and in others the wet-season form shows dark spots on the under surface occupying the exact positions of the ocelloid markings charac- teristic of the dry season. Group 1. (Type /. venilia.) Apical two thirds of primaries above veined with black ; under surface always showing dry-season markings ; the only probable seasonal difference consisting in the widtli of the border of the secondaries on the upper surface ; it is not, 134 Dr. A.

Allied to the preceding, but the ash-grey suffusion at the base clearer and more restricted, the disk (beyond the orange patch) sulphur-tinted ; the discal interrupted stripe terminating above the third median branch, the outer border and blackened veins narrower. The female differs more markedly, the white patches beyond the cell of primaries being washed with orange and widened and extended so as to be continuous with the white area below the cell ; the border of the secondaries is also similar to that of the male, not widened and bordered with grey scaling as in /. Reinwardtii. The under surface of both sexes differs from the latter chiefly in being less marked with black, the general pattern and coloration being very similar.

This is the largest and most perplexing group in the genus, and it is possible that I may not have sufficiently reduced the number of named species ; this, however, is, I think, prefer- able to reckless sinking of forms which are locally constant under one heading. In the late Capt. E. Y. Watson's review of the Indian species it is difficult to comprehend his meaning ; he regards the whole of the species of the present group as one ; but he says : — " /. pyrene is very subject to both climatic and seasonal variation, and many forms have been named. Of these some are fairly distinct, and the males can be compared as below " Now it seems to me that to discriminate between " a distinct climatic form " and " a species " we must have a universally accepted definition of what a species is, which is impossible : therefore, to my mind, if a thing is distinct it ought not to receive the same name as that from which it is admitted to be distinct, for to give the same name to two distinct things is to stultify the very object aimed at in nomenclature. In the present group the wet-season forms are usually almost unmarked below and the dry forms heavily speckled and ocellated, whilst the outer borders on the upper surface are, as a rule, considerably broader in the wet than in the dry forms, sometimes disappearing entirely from the second- aries of the latter. 10.

The Museum series consists of thirteen examples, and there is one specimen in the Hewitson collection. /. anexibia is the dry form and /. evippe the wet. This and the preceding species have long been confounded, of the Genus Ixias. 137 but the Chinese and Indo-Burmese forms differ somewhat. Taken collectively /. evippe runs somewhat smaller than /. rhexia) never attaining the expanse of wing which some of the wet-season examples of that species show ; the form of the wings in /. evippe is also rounder and more regular, the orange belt on the primaries is distinctly broader and extends further back into the discoidal cell, its front edge is diffused instead of sharply outlined ; the seasonal forms also differ less in size and in the width of the border on the upper surface of the secondaries than in /. rhexia. 12.

We possess ten examples of this species, of which seven belong to the dry-season form and exhibit the heavily black striated under surface which seems peculiar to this species. The female which I figured is that sex of /. verna (a white- winged species), which fact probably confused the late Capt. Watson, who regarded the present species as a form of /. pyrene rather than /. rhexia (to which it is much more nearly related) ; also, not having taken special notes of the type specimens, he erroneously identified the wet form of the species as typical, and (not possessing the dry form of the male) naturally concluded that the species was based, upon an extreme seasonal form of /. pyrene. The seasonal forms of /. latifasciatus hardly differ on the upper surface ; the border varies slightly in width in examples both of the wet and dry forms, one of our wet-season males showing a rather narrower border to the secondaries than any of our dry-season examples. Apart from the ground-colour of the wings this species is not at all unlike /. verna. 14. Ixias Birdi. rf . Ixias Birdi, Distant, Ann. & Mag. Nat. Hist. ser. 5, vol. xii. p. 351 (1883) ; Khop.

We have thirteen examples of this species, four of which are wet-season males and the remainder dry-season specimens of both sexes. The Hewitson collection contains four examples. Capt. Watson extended the range of this species over Southern India and regarded /. ihoda=I. kausala as the dry form of the species ; but the wet and dry forms of /. cinga- lensis are -absolutely identical on the upper surface, nor does /. kausala invariably possess the character upon which Capt. Watson defined /. cingalensis , for he says : — " It can be separated at once from all other forms of yellow Ixias by the greater extent of the basal yellow of the fore wing, which spreads into the upper median interspace." In our specimens of /. kausala the u basal yellow " extends more, less, or not at all into the upper median interspace. /. cingalensis can be picked out at sight from a crowd of nearly allied forms, but the distinction given above is useless as a guide ; its chief peculiarity is the narrowness and angu- larity of the orange belt across the primaries combined with the sharply defined and perfectly straight inner edge of this belt Irom subcostal vein to first median branch. 16.

Marshall in Natal and Mashonaland in 1895 and 1897. By ARTHUR G. BUTLER, Ph.D., F.L.S., F.Z.S., &c., Senior Assistant- Keeper, Zoological Department British Museum. (Plate XX.) The consignment of which the following is an account was received too late to be noticed in iny previous paper (P. Z. S. 1897, p. 835) ; it is, in some respects, of even greater interest, as including not only examples of several interesting new species and of many species new to the Museum series, but also the seasonal forms, authenticated by the donor, of a fair number of 187 DR. A. G. BUTLER ON LEPIDOPTEROUS INSECTS [Mar. 1, butterflies which have been regarded as distinct, and the varietal character of which is still called in question by some of the leading lepidopterists in this country. Speaking of the series from Mashonaland, Mr. Marshall observes : — " My Mashonaland collections, which I had intended to take home with me, have only just arrived here (or rather half of them), having been fourteen months coming down from Salisbury ! I find among the Teracoli a single dry-season male of T. hilde- brandti (which at the time I took to be a sport of T. annce) and also a female of T. pallene, Hopff., which is almost identical with the figure of your T. infumatus. " You will find three males and one female of a ' Lyccena 9 from the Karkloof, which Trimen considers to be only a variety of his L. niobe, but which I think is probably specifically distinct. It was discovered by Hutch in son and Barker in 1892 on Mr. Ball's farm in the Karkloof District near Maritzburg, and has apparently never been taken elsewhere. From their account (I have never seen it in life) it differs much in habits from typical L. niobe. It has been found only within a very limited area, a few acres in extent, flying rapidly over a patch of very long rank grass along the out- skirts of a clump of forest, and being on the wing only in autumn (viz. March and April). " L. niobe is distributed throughout Natal (it varies above in being either blue or brown), frequenting open country with short grass, and flying with a low, rapid flight ; it occurs only during the spring months. " It will be unnecessary to point out the differences in colouring, the most noticeable of which are the different position of the discal row on underside of secondaries and the presence of the metallic-green spot at anal angle in the ' variety.' I am sorry that the specimens are in such poor condition ; they were given to me by Mr. Ball." Mr. Marshall did not forward the male of " T. hildebrandti" but it probably is what he at first supposed — a mere sport of T. annce, corresponding in colouring with the T. calliclea ( = hilde- brandti) form of the Nyasa species. The two species are very closely related — little more than local forms, in fact. As regards the " Lyccena" I quite agree with Mr. Marshall that it requires a distinctive name ; it certainly is not identical with Catochrysops niobe, but is a finer and more brightly coloured species. The following is a list of the species received in Mr. Marshall's last consignment : — SATYRINJS. 1. SAMANTA PERSPICUA (var. SIMONSI Butl.).

A single small example of J. simia was obtained at Gadzima on the 30th December. 14. JUNONIA AURORINA Butl. Karkloof, Natal, 4200 feet, 29th to 31st January, 10th, llth, and 17th February, 1897. This is stated by Mr. Marshall to be the wet-season form of J. tugela^ but from his own dates it is certain that both fly together in February ; moreover, judging them by J. artaxia, they both have a dry-season under surface to the wings : I am therefore naturally very sceptical as to the identity of these two allied species. 15.

As I have suspected for some time, the seasonal forms of this species differ very little : that of the wet season has the black markings of the upper surface more pronounced, the costa of primaries rather shorter (giving a squarer character to the wing) than in the dry form, the markings below much better marked and the discal spots more decidedly ocelloid. I am now quite satisfied that J. trimeni has nothing to do with J. cuama or with J. simia. It will be remembered that I have always opposed the amalga- mation of these three very dissimilar species on the ground that they are undoubtedly 011 the wing simultaneously at all seasons. 17.

It' the single male from Mashonaland represents the normal dry-season phase, it only differs from that of the wet-season in its inferior size, and would be indistinguishable from starved examples obtained during the rains; both, however, differ very considerably from the wet form of the scarcely distinct A. nero of Eastern Africa. 28.

The so-called dry form of A. induna (because obtained in the dry-season) is a starved and somewhat \\orn little male, which, in my opinion, is only a belated wet form (provided that the heavy black apex really is seasonal, as it is said to be in certain species in the genus). The black apical patch in this example is slightly reduced, as might be expected ; but Mr. Marshall has himself admitted that in some of the species this black patch is a charac- teristic of the wet season ; in any case it is certainly a varietal, not specific, character, inasmuch as we have complete series of intergrades between the extremes in several forms of Acrcea. 29.

Mr. Marshall considers this to be the dry form of the following, of which he sends one curious example, said to be the intermediate form ; it certainly looks like it, but I should like more conclusive evidence than is afforded by one specimen which was obtained almost at the same time (in the same month) as A. asema. 30.

It would seem that the seasonal forms of this species differ chiefly in size, the dry form being smaller ; both phases agree in the large black apical patch, proving that this is not an invariable seasonal character, but by no means proving that it is not so in most of the species which possess it.

Nearly allied to C. mobe, larger ; differs above in the narrower deep smoky border to all the wings and the slightly clearer violet ground-colouring. On the under surface all the black and brown spots, which are more numerous, are distinctly edged with pure white ; the discal white band immediately following the transverse series of black spots is well defined and pure white in all the wings, whilst in the secondaries it is farther from the outer margin ; the submarginal annular markings are much wider, but indistinct on the secondaries ; the subanal black spot, however, is considerably larger, encloses a metallic-blue crescent, and is edged internally by a A-shaped orange marking : the upper surface of the female is shot with golden cupreous, and towards the base with lilac ; otherwise it resembles the male. Expanse of wings 39 millimetres. Three males and one female, Karkloof , Natal. This is the species referred to by Mr. Marshall (vide Introduction to the present paper) as probably distinct from C. niobe. There is, of course, just a possibility that it may prove to be the wet form of C. niobe, all our examples of which were obtained in September ; but I know of no other Catochrysops which exhibits such well-defined seasonal characteristics, whilst the different habits of the two insects are strongly suggestive of specific dis- tinction, though not necessarily conclusive. 44.

Distinctly smaller than $. homeyeri, the orange markings on the upper surface of the primaries entirely different, consisting normally of a spot in the cell followed by a transverse band 13* [10] 1898.] COLLECTED IN NATAL AND MASHONALAND. 196 beyond the cell ; the former is, however, sometimes carried obliquely downward, so as to unite with the latter (forming a large V-shaped character) ; the submarginal orange band consists of three portions, a spot near the costa and two transverse irregular bifid (rarely subconfluent) spots below it ; the anal orange patch on the secondaries of S. homeyeri is replaced by a sordid ashy patch marked with the usual silver spots ; the blue areas of S. homeyeri are dull greyish lavender in this species. Apart from the pale huffish-brown ground-colour, the under surface of the wings differs entirely from that of $. homeyeri : all the markings are edged with brown (not ferruginous or dull red) ; those of the primaries are emphasized on the costal margin by a series of about eight jet-black spots, they consist of three fairly regular equi- distant oblique bands between the base and the end of the discoidal cell, then follows a costal spot followed by an irregular transverse discal band dislocated at second median branch, this again is followed by a more or less denned, partly linear and partly normal band from costa to submedian vein and a very indistinct dusky submarginal line ; marginal line jet-black, internal area and fringe white somewhat pearly : the markings of the secondaries consist of two series of three spots towards the base parallel to the abdominal border, an irregular armillate band, acutely elbowed below the first median branch and interrupted on submedian vein, a short somewhat irregular discal band from costa to third median branch, and an unevenly zigzag submarginal band with indistinct outer edging ; marginal line black from anal angle to third median branch ; all these bands, as usual, have silvery centres ; fringe white, excepting at anal angle, where it is black, the spot above it being narrowly black, then dull chocolate, followed by a sprinkling of black scales ; the second spot on the other side of the submedian vein is externally of the ground-colour, internally silver followed by a sprinkling of black scales. Expanse of wings 29 millimetres. Gadzima, Mashonaland, 31st August, 13th and 25th September, 1895. As Trimen compares this species with his " S. natalensis " = S. caffer (to which, in my opinion, it has but little affinity), a description of its peculiarities compared with S. homeyeri will, I think, be useful to future workers. Hewitson's type is a very poor and damaged male, in which none of the orange bands on the upper surface are united ; the union of the two inner bands in one of Mr. Marshall's specimens shows that this species is not nearly related to any of the other described forms in the genus. In the S. natalensis group the cell-spot even when elongated into a band does not join the postmedian band, whereas the latter frequently joins the discal band. In 8. ella the postmedian and discal bands, being perfectly parallel, never could unite. 78. VlRACHOLA ANTALUS Hopff. $ , Mazoe District, 26th October 1894. [11] 197 DR. A. G.

From the ANNALS AND MAGAZINE OF NATURAL HISTORY, Ser. 7, Vol. i., April Descriptions of some new Species of Butterflies of the Subfamily Pierinae. By ARTHUR G. BUTLER, Ph.D. THE following species in the Museum collection have hitherto remained unnamed : — Mylothris bogotana, sp. n. . Allied to M. malenka, but differing in the pattern of the primaries, the tawny discoidal and somewhat shorter sub- median longitudinal streaks becoming sulphur-yellow at the extremities ; beyond and well separated from these are two isolated yellow spots placed obliquely, and beyond the cell three elongated spots of the same colour in an oblique subapical series instead of the oblique quadrifid belt of M. malenka. Expanse of wings 75 millim. Santa FcS de Bogota (Stevens). B. M. This is not likely to be a variety of the Venezuelan species, as it is believed that in this group the variations of the female are not very great. Elodina Walkeri, sp. n. Allied to E. perdita, the male with shorter primaries ; the apical patch always as broad as in E. perdita ? , and not incised or dentated below the third median branch : apex of primaries below silvery, with three increasing blackish sub- apical spots in an oblique series ; a sulphur-yellow subcostal streak from base, and in the discoidal cell a saffron-yellow suffusion : secondaries silvery white ; a blackish dot at end of cell and four or five blackish discal spots in an obtusely angular series between the nervures. Expanse of wings 38 millim. Port Darwin (J. J. Walker). B. M. We have six examples, of which five were collected by Mr. Walker ; the sixth is one of our oldest specimens, the registered locality for which was simply " New Holland." Elodina baudmiana, sp. n. Also allied to E. perdita, but distinctly smaller and very uniform in pattern : above pearly snow-white ; primaries with costal margin smoky greyish, basal half of costal border flesh- 295 New Species of Butterflies of the Subfamily Piermje. tinted, a rather narrow blackish apical patch, widest on costa (where it occupies about the external two-fifths of the margin) and tapering to extremity of second median branch, its inner edge dentated; a small and slightly browner spot at extremity of first median branch : below like the preceding species, but the black spots often very indistinct. Expanse of wings 33-38 millim. Baudin Island (J. J. Walker). B. M. Of this species we have fourteen examples. Terias Chamber lain I, sp. n. ^ . Bright gamboge-yellow; costal margin of primaries very delicately black, excepting towards the base ; costa sprinkled with black scales to end of discoidal cell ; extreme base of cell and of submedian vein marked by short black dashes ; outer border narrowly dark brown, commencing at about two-fifths of the length from apex and tapering to ex- tremity of first median branch, its inner edge zigzag from the third median branch hindwards : secondaries with a con- spicuous pure white glandular patch towards base above the subcostal vein ; veins terminating in very minute black dots followed by orange spots at the base of the fringe : bo ly normal. TJnder surface gamboge-yellow, sparsely and very finely irrorated with brown atoms; a well-defined black spot at the end of each discoidal cell ; fine black dots followed by orange angular markings terminating the veins, the orange markings uniting and covering the fringe towards apex of primaries ; a pure white glandular patch between median and submedian veins towards base of primaries ; a very indistinct W-shaped series of squamose brown spots crossing disk of secondaries. Expanse of wings 30 millim. Bahamas (Neville Chamberlain). B. M. We only possess one male of this pretty little species. If Felder's statement was correct that his T. smilacina nearly approached T. smilax both in pattern and structure, this would be the second New- World species of the T. Iceta group ; but an examination of Felder's description clearly shows that his species did not possess the glandular patches which charac- terize the T. Iceta group, and therefore was " wirklich nicht zunachst verwandt " to T. smilax (as he ought to have said). 1898.] ON LEPIDOPTERA FROM BRITISH EAST AFRICA. 395 [From the PROCEEDINGS OF THE ZOOLOGICAL SOCIETY OF LONDON, May 17, 1898.] On a Collection of Lepidoptera made in British East Africa by Mr. C. S. Betton. By ARTHUR G. BUTLER, Ph.D., F.L.S., F.Z.S., &c., Senior Assistant- Keeper, Zoological Department, British Museum. (Plates XXXII. & XXXIII.) Mr. Betton's collection is a singularly interesting one, rich in rare and new species, three Butterflies and twenty-six Moths from the present series being now described for the first time. Among the Butterflies also I may call attention 'to a suite of Acrwa chilo, females of A. crystallina, the wet-season forms of both Teracolus hetcvra and T. puniceus, the dry form of T. leo, a number of examples of T. venata, and an example of the rare Alcena picata, a species new to the Museum collection. Although Mr. Betton desired to retain a collection for his private use, yet he sanctioned the whole of the types of new species, and examples of all species needed to perfect the National collection, being retained. Among the Heterocerous Lepidoptera, manv of which were only represented by single specimens, he has thus suffered somewhat severely in the interests of science ; but in the Butterflies there was considerably less required in proportion to the numbers collected. Mr. Betton's line of march extended from Mombasa in a north- westerly direction by way of Samburu, Tarn, Voi, and Ndi to Tsavo '.

One very shattered male nearly approaches J. pyriformis in colouring, and shows the intensely dry character of that insect on the under surface. It will be remembered that in 1896 (P. Z. S. p. Ill) I suggested the possibility of the latter being a form of J. aurorina. As the fact that the latter and J. tugela fly together in the wet-season in S. Africa seems to disprove the statement that they are seasonal forms of one species, it would appear more probable that J. pyriformis is the dry form of J. aurorina, the single example of the former in this collection having evidently been a considerable time on the wing ; however, we need more evidence before deciding this point, especially as all three of these species have dry-season undersides to the wings. 15.

It is now evident that this is an Eastern (not Western) species, and an examination of its neuration and other structural characters, as well as a comparison of the markings of the under surface, make it evident that it is nearly related to Parapontia undularis. Mr. Betton's specimens are slightly larger and more distinctly washed with buff on the costal and apical areas of the primaries and the secondaries upon the under surface than in the type. 47.

This species is exceedingly variable on both surfaces ; the black border of the primaries above is sometimes reduced to an apical patch, that of the secondaries being reduced to a row of spots or wholly absent, whilst on the under surface the submarginal row of spots is either faintly indicated or entirely wanting. If only single examples of the extreme types were received, they would be unhesitatingly described as distinct species : I have no doubt that T. nero and T. heriha are varieties, for we have exactly similar specimens, but with smaller spots, whilst the size of the spots is unquestionably extremely variable. 48.

The variation of the markings of the upper surface in this species is considerable and may be thus described : — 1. — Primaries. Costal markings not entering the discoidal cell, but forming a K-shaped marking immediately beyond cell ; outer border wide on costa, rapidly tapering and becoming linear after second median branch, not reaching external angle. Secondaries. Outer border extremely narrow. Mgana. 2. — Primaries. Costal markings extending quite across discoidal cell and completely confluent with outer border, which tapers gradually to external angle and extends a short distance along the inner margin. In this variety the outer border occupies about a third of the wing. Secondaries. Outer border broad in the centre, squamose at both extremities. One shattered and worn starved example. Mgana. 3. — Primaries. Costal markings extending across discoidal cell, but separated from outer border, which is slightly narrower than in var. 1, but continued to inner margin. Secondaries. With tolerably broad outer border of nearly uniform width (typical D. hildegarda). Sainburu. 4. — Primaries. Costal markings as in var. 1, but outer border continued to inner margin. Secondaries. Outer border distinctly narrower than in var. 3, and especially towards anal angle. Taru. 5. — Like var. 3, excepting that the outer borders of all the wings are broader (typical D. freyd). Taru.

We are so badly off for this species that it is possible that similar varieties of the species may occur also in Natal.

The single example obtained differs so much from Hewitson's type in the pattern of the upper surface, that, if we had not possessed an intermediate specimen from West Africa, I should have concluded that this Eastern variety must be distinct : the secondaries would be best described as bright orange tawny, the base, abdominal border, and a submedian streak smoky greyish brown ; the usual bright blue subcostal sexual spot ; outer border narrowly dark brown, slightly widest at apex : the orange patch on the primaries is also much larger than in typical V. lorisona.

The dry form of the male differs chiefly from the wet form in the rosy colouring of the apex of the primaries and the whole surface of the secondaries on the under surface, whilst extreme wet types of the male are not only pearly white below, but show an oblique discal series of black spots between the costal vein and second median branch on the underside of the secondaries : the female of the dry phase resembles the wet form of T. plileyyas on the upperside and the dry form of that species on the underside ; it is, however, larger and shows heavier black markings.

The dry form is quite new to science (excepting for the single starved and faded male without locality noted in my Revision of the genus, cf. Ann. & Mag. Nat. Hist. ser. 6, vol. xx. p. 501, 1897). The male at this season chiefly differs from that of the wet-season in the bluer tint of the grey basal area of the primaries, but the orange is sometimes carried above the first median branch and the dusky submarginal markings are sometimes wanting ; the underside differs in its flesh-coloured suffusion, which is very well- defined at apex of primaries and over the basal, costal, and internal areas of the secondaries. The female of the dry form resembles T. ccelestis of Swinhoe (the dry form of the female of T. hdlimede), but has the discal black spots across the primaries widely separated from the outer border by a broad intervening belt of the yellow ground-colour: on the underside the apex of the primaries and the whole of the secondaries are fleshy brown, and the transverse spots are much darker than in T. ccelestis. 93.

Felder's figure is either extremely bad, or this is a new species ; it is very probable that the former is the correct explanation of the differences which exist between the two, and that the illustra- tion was taken from a frayed and faded male. The species is quite new to the Museum, though nearly allied to the southern H. delegoryuei, from which it differs chiefly in the trisinuated inner margin of the central belt of the primaries, its regularly undulated outer edging, the white margin of which is emphasized by a grey- mottled series of very indistinct markings across the disc. The female has the outer margins of the wings even more distinctly dentated than in that sex of H. 'delegorguci, but it is probable that this may not be the case in the male. 188.

The species is also related to Lasioptila ansorgei Kirby (=Saturnia Tcuntzei Dewitz), which must be referred to Dr. Hol- land's genus Goodia. Kirby's L. pomona is not congeneric with the latter ; therefore if his generic name is retained it must take L. pomona as type, instead of L. ansorgei. I have named this pretty little species after the learned author of the genus, to whom all students of African Lepidoptera owe a debt of gratitude for his admirable work. ElTPTEROTIDjE. TROTONOTTTS, gen. nov.

We have males in the Museum from Ambriz and Accra ; they show a tawny or brown-edged spot at the base of the median branches of the primaries above, more distinctly than in the female (where it only appears like an excrescence of the discoidal streak) ; the median vein and base of the submedian vein in the example from Ambriz are also yellowish (which doubtless suggested "Warren's unsatisfactory name for the species). The darker portion of the secondaries in specimens from Accra is also darker in both sexes than in the male from Angola, but this is doubtless a variable character ; the pectinations of the antennae in male examples are pale orange. The veins on the under surface of the primaries being partly orange-tawny, I have modified the manuscript name proposed by "Warren. 200.

From the ANNALS AND MAGAZINE OP NATURAL HISTOBY, Ser. 7, Vol. ii., July 1898. On the Butter/lies of the Genera Leptophobia and Pieria. By ARTHUR G. BUTLER, Ph.D., F.L.S., F.Z.S.,&c. IN spite of adverse criticism, I have seen no reason to change my decision either as to the distinctness of Leptophobia or as to what should be regarded as typical Pieris. Strictly speaking, perhaps, Parnassius apollo should be regarded as the type of Pieris, Schrank ; Scudder, however, considers Ganoris rapce to be the type, regarding the closely related G. brassicce as generically distinct. I have clearly proved that the trivial characters upon which these two nearly allied " cabbage- butterflies " were separated are utterly unreliable, being inconstant in the extreme. If we were, on the other hand, to make Parnassius apollo the type of Pieris, it would not only create hopeless confusion, but would necessitate giving a fresh name to the subfamily Pierinse, a course not to be desired by any who keep in view the sole object of nomenclature. As before, therefore, I accept Boisduval's definition of Pieris, taking P. amathonte ( = P. demophile $ ) as its type. In the ' Biologia Centrali-Americana ' the genus Pieris is expanded to include Synchloe, Mylothris, Leptophobia, and Glutophrissa ; but personally I prefer to keep all groups having constant structural differences, whether of neuratiou or other details, as separate genera. As regards the state- ment that P. protodice (Synchloe) is sexually inconstant in neuration, I can only suggest that this state of things is indi- vidual and abnormal, inasmuch as nine out of our ten male examples show the apical furca in the primaries quite as 14 Dr. A. G. Butler on the Butterflies of clearly as in our six females. This, I do not for a moment doubt, the authors of the ' Biologia ' will frankly admit when they have again investigated the point. The following is a list of the species so far as they are known to me : — LEPTOPHOBIA., Butler. 1. Leptophobia eleone. Pieris eleone, Hewitson, in Gen. Diurn. Lep. pi. vi. fig. 6 (1847). Pieris Smithii, Kirby, Trans. Ent. Soc. 1881, p. 357 ; Rhop. Exot. i. pi. i. figs. 3, 4 (1888). Venezuela, Bogota, Bolivia, Quito, Ecuador. B. M. P. Smit/rii is evidently a slight variation, differing only in the narrowness of the posterior portion of the outer border of the primaries ; the width of this border varies a good deal in L. eleone. 2. Leptophobia eleusis. Pieris eleusis, Lucas, Rev. et Mag. de Zool. 1852, p. 331. Pieris suadetta, Felder, Wien. ent. Monatschr. v. p. 79 (1861). Venezuela. B. M. I think it very doubtful whether the following is distinct from this. 3. Leptophobia helena. Pieris helena, Lucas, Rev. et Mag. de Zool. 1852, p. 332. Quito. B. M. 4. Leptophobia aripa. Pieris aripa, Boisduval, Sp. Ge*n. Lep. i. p. 528 (1836). Pieris balidia, Boisduval, t. c. p. 529. Pieris elodia, Boisduval, I. c. Rio Janeiro, Bolivia, Venezuela, Panama, Costa Rica, Guatemala, Mexico. B. M. Our examples of L. balidia (from Rio Janeiro) have the under surface of the secondaries and apex of primaries more buff-coloured than Central-American examples ; but the Bolivian example is somewhat intermediate. 5.

Nearly allied to the preceding species. 8. Leptophobia stantnata. Pieris stamnata, Lucas, Rev. et Mag. de Zool. 1852, p. 330. Pieris euthemia, Felder, Wien. ent. Monatschr. v. p. 80 (1861). Venezuela. B. M. 9. Leptophobia penthica. Leptalis ? penthica, Kollar, Denkschr. Akad. Wiss. Wien, math.-nat. Cl. i. p. 360, pi. xlv. figs. 11, 12 (1850). Bogota and Ecuador. B. M. 10. Leptophobia subargenteat sp. n. (£. Above very similar to the same sex of L. tenuicornis, but the base of primaries blacker, the white markings more cream-coloured, the large patch barely extending above the second median branch (so as to leave a much wider interval between it and the subapical bifid spot) ; secondaries much less blue, the inner bordering of the much larger creamy white patch being rather silver-grey. Primaries below with costa and fringe sulphur-yellow, apical area silver crossed by black veins ; white area rather more extended basally than above and pure white, subapical white spot slightly broader : secondaries silver, with black veins ; basal lobe daffodil- yellow in front, saffron behind. Body normal. Expanse of wings 58 millim. Pucartambo, Peru (Whitely). Type B. M. Evidently related to, but distinct from, the following. 11. Leptophobia semiccesia. Pieris semiccesia, Felder, Reise der Nov., Lep. ii. p. 176 (1865). Bogota. This species seems to approach L. penthica, but with no white on upper surface of secondaries ; the secondaries and apex of primaries below silvery rather than nacreous. The 16 Dr. A. G. Butler on the Butterflies of description almost agrees with L. philoma, but Felder speaks of the subapical fasciole as tripartite. 12. Leptophobia olympia. Pieris olympia, Felder, Wien. ent. Monatschr. v. p. 80 (1861). E. Peru (registered Nauta). B. M. In the Hewitson collection a specimen, from Bolivia, stands under L. tovariaj from which species I think L. olympia very doubtfully distinct; it was described from a Venezuelan example. 13. Leptophobia tovaria. Pieris tovaria, Felder, Wien. ent. Monatschr. v. p. 80 (1861). $ , Bogota. B. M. 14. Leptophobia subflavescens. Pieris subflavescens, Kirby, Ann. & Mag. Nat. Hist. ser. 5, yol. xix. p. 362 (1887). New Grenada. Near to L. tovaria; almost the same on upper surface. 15. Leptophobia philoma. Pieris philoma, Hewitson, Equat. Lep. p. 79 (1870). Ecuador. Type coll. Hewitson. Should this prove to be Felder's L. semiccesia it will have to sink ; but it is possible that the species of Bogota may prove distinct. 16. Leptophobia ccesia.

This genus separates into several natural groups, the first being the P. demophile group, in which the females vaguely remind one of Ithomiinse (such as S-n's) • the second is (he P. viardi group, the females of which are often more like; Tithoreaj the under surface of the secondaries often riehly coloured in both sexes; the third is represented by P. /t'ti/etd (P. mouuite auct. plur., nee Linn.) and its varieties, some- what short-winged Belenois-like butterflies ; the fourth and last is represented by the P. bunice group, and unites charac- teristics of Catopsilia and G-anorix, all the males exhibiting well-developed patches and streaks of thiekiiiel soiling on the wings, but combined with the long slen ler antennie and style of neuration of the later types of the Pierirue.

Above much like P. locusta, but usually with one or two extra white spots in the border and with the narrow part of the border, at the posterior angle of the primaries, better defined : on the under surface the differences are better marked, the border of the primaries being produced inwards upon the first and second median branches as in P. locusta^ but not so imperfectly, the greyish diffusion of that part of the border in P. facusta being rilled in in the present species : iii the secondaries the red, orange, and yellow markings are the Genera Leptophobia and Pieris. 19 all less vivid and there is a broad pale belt across the wing which includes the greater part of the discoidal cell, so that the lower ramus of the dark discoidal furca is clearly seen to be bordered on both sides with chrome-yellow; the submarginal yellow spots are rather more elongated than in P. locusta. Expanse of wings t)7 millim. $ . Curiously resembles Tithorea Pavonn. Above black: the primaries with a broad sulphur-yellow patch, paler externally, commencing just above the base of the median vein and divided by this vein and its first branch, at the middle of which branch it terminates ; below this a diffused yellow streak traversed by the submedian vein ; a slightly irregular pearly white oblique macular band beyond the cell from costa nearly to outer margin, its inner edge angulated at subcostal vein, its last inferior spot small and well divided from the remaining divisions ; two spots placed subapically, the upper one bifid ; a larger spot near posterior angle : secondaries with brown costal area, below which is a broad sulphur-yellow belt, whitish at each extremity, from abdo- minal margin to second subcostal branch, above which are a few yellow scales ; this belt is deeply incised upon the veins, but especially upon what would now be called the " upper " radial ; a submarginal series of white spots. On the under surface the primaries are nearly as above, excepting that there is a pale patch at apex tinted with grey-brownish and yellow, and partly enclosing the bifid subapical spot ; below this and near outer border are three bifid yellow spots, the last being the terminal spot of the postmedian stripe : the secondaries nearly resemble those of the male, but are altogether more vivid in colouring, the broad belt crossing the cell being mostly white and the streak bordering the discoidal < -shaped character (false vein) bright cadmium-yellow.

Expanse of wings 70-79 millim. ? . Not unlike the female of P. mandela, but much larger, the secondaries above with the whole base almost to the end of the cell suffused with greyish brown : the primaries on under surface not sulphur-tinted at base and the secondaries more pink in tmt, tlie brown portions more coffee-coloured, the submarginal spots larger.

Southern States of N. America, the West Indies, Central America, and a great part of the Southern continent. With so wide a range it is naturally extremely variable, a perfect series of gradations existing between typical P. phileta and the feebly bordered P. automate ; these variations may be somewhat arbitrarily divided into seven grades, none of them apparently being confined to any particular region. The species has hitherto stood in collections as P. monuste of Linnaeus, with which some of the older authors were the first to confound it; but the description in the 'Museum Ludovicas Ulricas ' cannot refer to this butterfly, inasmuch as, in the first place, no mention is made of the dentated character of the inner edge of the outer border of primaries, but, on the contrary, that of the secondaries is specially described as " denticulato-fuscus " ; in the second place, no mention is made of the elongate subapical white spots on the primaries ; and, lastly, the wings below are said to be concolorous, ex- 22 Dr. A. G. Butler on the Butter/lies of cepting that the borders show a greyish shade answering to those of the upper surface — " loco fusci coloris tantum cine- rascentes ad marginem." The description is much more likely to be intended for Udaina cynis, only the under surface of the primaries in the latter species is almost too strongly coloured and the dentated character of the border still obtains on the upper surface. The type being lost, it is by far the best plan to let the name lapse unless something perfectly answering to the description can be found. Possibly Mylothris phaola or an allied form may be intended. Section 4. 16. Pieris j sp. n. ? Four specimens of a species allied to P. sevata, but with more produced costa and more broadly bordered outer margin to primaries ; the apex of primaries and the secondaries below sericeous pink. Four males, Panama. B. M. I have been unable to find a description of this species, •which, however, I prefer to leave for the consideration of the authors of the * Biologia Centrali-Americana.' It vaguely resembles Glutophrissa castaliat but differs in structure and in the colouring of the under suiface; the primaries with much straighter outer margin, all the wings with streaks of thickened scales bordering the veins, and the anal segment, with no trace of the dense prominent brush projecting from the base of the clasps (the presence of the brush in both sexes being the chief character upon which I founded the genus Glutophrissa}) a feature wholly wanting in either sex of Pieris. 17.

On some new species of African Picrimv in the col- lection of the British Museum, with notes an seasonal forms of Belenois. By ARTHUR G. BUTLER, Ph.D., F.L.S., &c. [Read November 16th, 1898.] WHILST arranging the Pierinse of the genus Phrissura, I discovered three males of a species which is certainly undescribed, mixed up with the series of P. sylvia (the dry-season form of P. eudoxia), and in the Hewitson col- lection I discovered the female of the same species I now describe. Phrissura perlucens, sp. n. <£ . Above nearly resembling P. sylvia, but with the inner edging of the black outer border of primaries more blurred, less distinctly dentate- sinuate, the basal patch of lemon yellow without the least tinge of orange ; on the undersurface the border far more distinct than in P. sylvia, irrorated with dark brown, yellowish externally ; the base bright lemon yellow as above (not orange, as in P. aylria} ; the secondaries also with the costal area at base bright lemon yellow instead of orange. Expanse, 50 — 61 millim. $ . Similar in pattern to the female of P. sylvia, but with the ground-colouring of all the wings above pure white ; the border of primaries and marginal spots of secondaries rather broader than in P. sylvia ; primaries below bright lemon yellow at base, slightly washed with saffron on costa ; apical area irrorated with grey- brownish and with an oblique subapical stripe of the same colour ; secondaries with the base of costal area golden yellow, slightly more saffron on costal margin : no trace of the ochreous bordering common to the undersurface of all the wings in P. syhia. Expanse, 64 millim. Hob. ANGOLA and GOLD COAST (Mus. Brit.}. Phrissura narcissus, sp. n. 9 . Primaries bright ochreous ; a grey subapical crescentic band ; •veins pale buff, partly dividing a marginal series of black spots ; TRANS. EXT. SOC. LOND. 1808. — PART TV. 432 Dr. A. G. Butler on new African Pierinse secondaries bright lemon yellow with a marginal series of cordiform dark brown spots terminating the nervures ; primaries below ochreous with pale creamy costa, the cell suffused with saffron to- wards the base, but not abruptly ; subapical grey band obsolete, marginal black spots smaller than above, fringe black ; secondaries butter yellow with deep saffron basi-costal area ; spots on margin as above ; pectus creamy yellow ; abdomen flesh-tinted. Expanse, 59 millim. Hob. ANGOLA (Coll. Hewitson) . This is so strikingly distinct from everything else in the genus that I do not hesitate to name it in spite of the fact that it is a female; the male will probably be found to have a broad blackish border to the primaries. In the genus Belenois, of which I have recently completed the arrange- ment, the seasonal forms are always tolerably well-defined. Belenois, though nearly related to Phrissura, has a different style of marking ; the males never have a pencil of hair between the anal clasps as have those of Phrissura ; the primaries as a rule are more produced, the costa being longer, so that the wing-outline more nearly resembles that of Appias ; there are however exceptions to this rule in a few specimens which more nearly approach Phrissura in outline. A few notes on some of the seasonal forms in Belenois may perhaps be useful to the systematist ; they follow the usual rules of variation which have, in many cases, been more or less satisfactorily proved by collectors and breeders of Pierinse ; so that there can be no reason for refusing to accept them as facts. If they are rejected as seasonal forms, they must be accepted as variations, inas- much as (in nearly every case) the intermediate phase occurs. Belenois hedyle, Cramer. This is a wet-season phase, of which B. rhena is the female of the dry phase. In the Museum there are six males and one female of the wet phase in addition to five examples in the Hewitson collection ; of a perfectly inter- mediate phase we have five males ; of the dry phase we have three males and two females, one additional example being in the Hewitson collection. Belenois thysa, HopfT. The Angolan form of this species differs somewhat from the more Southern and the Eastern type of the species, and on seasonal forms of Belenois. 433 representing a slight local variation of which B. meldolw is the dry phase. The typical figures of the species re- present the intermediate phase, the wet phase of which has heavier black borders with which the subapical spots on the primaries are often united ; the dry phase is repre- sented by B. sabrata. A singular form of the species occurs sporadically in the area bounded by the Victoria Nyanza and Lake Nyasa ; the females of this form differ so remarkably in outline and in the more or less lilacine greyish suffusion of the under surface that one might be excused for believing that they represented a distinct species. Belenois dentigera, Butl. This species, which is related to B. calypso, was based upon a dry -season male collected by Emm Pasha. The intermediate phase is represented by B. welwitschi of Rogenhofer (who states that it was collected in Angola !) ; of this phase we have a male obtained by Emin Pasha at Kangasi and three males from Nyasa-land. Of the wet phase, a heavily marked and more brilliantly coloured edition of the intermediate phase, we possess four males and one female from Nyasa-land. Belenois instabilis, Butl. Of this species we possess both sexes of all the phases, the wet form of the female somewhat resembling that sex of B. creona on the upper surface ; both sexes are very heavily black-veined on the under surface. The inter- mediate phase bears much resemblance on the under surface to the wet phase of B. dentigera, excepting that the insect is considerably smaller, the apical markings on the primaries are sulphur yellow and the median vein of the secondaries, with its branches, is black. In the dry form the black markings are reduced on both surfaces, and the secondaries below are more ochraceous. Belenois subeida, Felder. Related to the preceding ; we possess only single males of the wet and intermediate phases and a female of the dry phase. The species doubtless replaces B. instabilis in North Africa : whilst it is much more heavily bordered on 434 Dr. A. G. Butler on new African Pierinse the upper surface, it is altogether less brilliantly coloured below. Belenois crawshayi, Butl. We now possess wet, intermediate, and dry phases of both sexes of this species ; B. diminuta was based upon the female of the dry phase. In the collection made by Dr. Gregory in British East Africa is a species related to the preceding which I con- founded with the Eastern form of B. zochalia : a careful study of the two has now convinced me that this was an error, the form of the wings being constantly very different, and the costal margin of the primaries and the abdominal margin of the secondaries being noticeably shorter. Belenois formosa, sp. n. $ Belenois zochalia (part), Butler, P.Z.S., 1894, p. 579, pi. xxxvii, fig. 3. $ . Primaries white above, the basal area nacreous ; secondaries white or pale sulphur yellow ; markings as in B. zochalia. At first I was inclined to regard this as the dry phase of the East- African representative of B. zochalia, but the coloration and vivid marking of the male are so distinctly characteristic of a wet-season phase, that I was compelled to abandon this idea as soon as it occurred to me. Un- doubtedly the pattern of the females of both forms is very similar, but nevertheless I feel sure that two species exist ; we have five males and three females of B. formosa. Of typical B. zochalia from South Africa we have wet, intermediate, and dry forms of both sexes; they differ chiefly in the definition of the black markings on the under surface. Belenois sever ina, Cramer. Of B. severina we have an immense series commencing with the wet-season B. infida (P.Z.S., 1894, pi. xxxvii, figs. 1, 2), passing through two fairly defined intergrades, of which one is typical B. severina, to the extreme dry form, which nearly resembles B. creona on the under surface. B. loguensis of Felder is a Northern race of the species showing less variation, the wet phase being not much unlike the first intermediate phase of B. severina, but the dry phase more nearly approaches B. creowa. and on seasonal forms of Belenois. 435 Belenois leucogyne, Butl. This interesting species seems to possess a dry phase only. Belenois creona, Cramer. The wet form of this species seems to be extremely rare ; we possess only one pair ; above it resembles the common intermediate phase, but on the under surface the veins are lilacine grey in the male and black in the female. The best characters for distinguishing B. creona from J5. severina consist in the smallness of the subapical spots on the upper surface of the primaries in the males, the black and scarcely spotted border of the secondaries in this sex and the white ground-colour of the female streaked on the under surface with deep ochreous. B. creona is essentially a West- African species ; B. severina Southern and Eastern. Belenois johannse, Butl. I know this only as a dry-season phase ; it is a very distinct species. Belenois mesentina, Cramer. We have a very extensive series of this species, B. augusta = agrippina = lordaca being the wet phase, B. me- sentina = syrin& intermediate, B. auriginea dry, and B. taprobana being an insular dry phase differing in the Slacker outer border to the male primaries, on which the subapical spots are less prominent. Belenois teutonia, Fabr. The wet form is B. clytie = niseia ; the intermediate form shows a narrow break between the discocellular bar and outer border in both the primaries and secondaries of the female, but no noticeable difference in the male ; in the dry form the discocellular bar is well separated from the border, and the white spotting of the border in both sexes is clearly defined. Belenois peristhene, Boisd. jThe wet form has the secondaries below black with a .submarginal row of orange spots. We have two examples 436 Dr. A. G. Butler on new African Pierinse from New Caledonia in which the whole basal area of the primaries below is also orange, as in B. Java ; these are probably either reversional sports or the result of hybridism between the two species. The intermediate form differs in having several squamose subbasal orange patches on the under surface of the secondaries; the dry form has the cell and a series of patches below it white, the basi- costal patch and submarginal spots remaining orange. Belenois clarissa, Butl. The seasonal differences in this species much resemble those of B. peristhene, the orange spots of the under surface being replaced by sulphur yellow; we have all the phases in both sexes. Of B. picata we possess only a dry-season phase. Belenois Java, Sparrm. B. deiopeia, Don., is the dry phase. We possess an intermediate from the New Hebrides; as the species occurs as far to the East as the Friendly Group, it certainly crosses the range of B. peristhene, and is quite likely to hybridize with it. Belenois raffrayi, Oberth. This is a wet-season form, and, without examining specimens of the allied B. margaritacea, I would not suggest that there may be more than affinity between them. It is quite possible that they may be perfectly distinct. Respecting B. gidica, much confusion has arisen ; I may begin by stating emphatically that B. gidica is not the wet-season form of B. dbyssinica, and that B. allica of Oberthlir is not the B. allica of Boisduval, but is identical with B. abyssinica. Furthermore, there are two South-African species of the group, easily separated by any one who has an eye for form and pattern. Belenois gidica, Godt. Differs at a glance from B. gidica of authors in the lack of con- tinuity between the discocellular black spot of primaries with the costal borders, the distinctly narrower and blacker outer borders of the primaries, the fourth white spot on which opens without break into the ground-colour, so as to form a quadrate excision of the and on seasonal forms of Belenois. 437 border. On the under surface the differences are niudi greater ; the apical brown border is unbroken, with three small whitish spots in- ternally as above, whitish veins, and five tear-like whitish .sub- marginal dots between the veins. Secondaries with irregular brown borders interrupted by diffused whitish spots internally and enclosing six distinct submarginal white spots; veins pale; an oblique ab- breviated brown spot at the end of the cell, but no other markings. Expanse, 57 millim. Hal. CAPE OF GOOD HOPE. Two males of the wet-season phase of this very distinct species were in the God man and Salvin collection associ- ated with B. cjidica of Trimen and others. To the latter I propose to restore the name of B. west-wood i, Wallgr. Belenois abyssinica, Lucas. The Godman and Salvin collection contained two males, and the Museum series a female of the wet-season phase of this species. It differs from the wet phase of B. wcst- t'-oodi above in the almost confluent character of the marginal spots on the male secondaries; the differences below are considerable, the ground-colour being much yellower, and all the dark brown markings on the basal area of the secondaries being wholly erased, bringing it decidedly nearer to B. yidica. The differences between the dry-season forms of the two species do not appear to be so marked, though they are of the same nature, the rusty ground-colour not being so well suited for emphasizing the absence of dark mark- ings as the primrose yellow of the wet-season phase. Belenois westivoodi, Wallgr. We have a long series of this species, the female of which is very variable. I suspect that the most typical wet phase is represented by the more heavily bordered and distinctly marked examples, but the change from heavy to light borders is so gradual that I have not attempted to distinguish an intermediate phase. One of our female examples in which the upper surface is very lightly marked shows a distinct approach to the dry form in the coloration of the under surface. Of the dry phase we have five examples from Eastern Africa as far south- ward as Natal, and there is an equal number in the Hewitson collection. 438 Dr. A. G, Butler on new African Pierinte. Belenois occidentis, sp. n. Allied to B. westwoodi, but distinctly larger, the apical area of the primaries irrorated with grey, the outer border greyer than in B. westwoodi, the irregular transverse subapical band interrupted in the middle ; the veins blackened to the cell, excepting the first two median branches ; the discocellular black bars continued round the end of the cell as far as or beyond the emission of the second median branch ; secondaries with a well-defined black discocellular dash and several black traces of the'discal markings of the under sur- face ; black marginal spots and fringe as usual. On the under surface nearly the whole of the veins are brown, darker on the primaries ; in the wet phase the primaries show a grey basal patch terminating in a black discoidal streak ; the black discocellular bar is continued broadly to the first median branch along which it runs to the middle, so that it forms a large Z-shaped character ; in the dry phase >the discocellular bar runs backward only half way to the origin of the first median branch. In the character of the second- aries this species is like B. westwoodi on the under surface. Expanse, -64 millim. Hob. CONGO ; LOANDA (Mus. Brit.). These examples were received from the Godman and Salvin collection, a male (wet phase) from the Congo, and a pair (dry phase) from Loanda. There is very little doubt that this is the species for which Boisduval pro- posed his manuscript name of " Pier is allica" but M. Oberthtir having published the name as applying to B. abyssinica, it has become a synonym and cannot now be resuscitated. 1898.] ON BUTTERFLIES FROM THE HARAR HIGHLANDS.

The small collection of which the following is an account was somewhat hurriedly made, all the specimens having been secured l in about three days, at an elevation of from 4000 to 8000 feet on the Harar Highlands. It is therefore not surprising that most of them are a good deal shattered ; some of them are nevertheless very acceptable additions to the Museum collection : one species is new. So little is known even now of the Lepidopterous fauna of this part of Africa that every consignment received thence is of importance and is worthy of careful record, even though many of the examples may have no further value when that record has been published. 1 They do not appear to hare been netted, but rather knocked down and captured by hand.

The following specimens in the collection are worthy of mention : — The example of Charaxes brutus is not only interesting on account of the narrowness of the white band across the primaries, but also because of the prominence of the grey lunulated sub- marginal line of the secondaries. Acrcea antinorii, of which twro rather damaged specimens were obtained, was previously known to me only by the illustration (Annali del Museo Civico di Geneva, xv. tav. i. fig. 3). The male of MylotTiris yulei more nearly approaches the typical female than the male which I described ; but there is not sufficient evidence to warrant their separation at present. The example of Colias marnoana is larger than those which we previously possessed and tends to link it to C. sareptensis. The two males of Papilio erinus are actually more or less inter- mediate between the var. pseudonireus and Papilio bromius ; it therefore seems probable that P. erinus and P. bromius will eventually have to be united, in spite of the considerable differences which exist on both surfaces between the extreme forms. A pair, unfortunately much shattered, of P. antinorii was obtained.

By ARTHUR G. BUTLER, Ph.D., F.L.S., F.Z.S., &c. The present series was forwarded to our Secretary for me by Mr. J. F. Cunningham, Secretary to the Administration, in the hope that they might be useful for the Museum collection, to which I may at once say that it forms a most welcome addition. Chikala, north end of Lake Shirwa, being new collecting-ground, might be expected to yield new species to the explorer ; but the present consignment (which comprises examples of only twenty- one species) contains nothing hitherto unnamed, although one of the ten forms of Charaooes in the collection is of considerable interest to me, not only as being the first female specimen which we have acquired, but as proving that I was correct in placing C. lactetinctus next after C. azota in ray arrangement of the genus. Considering that most of the specimens in this collection belong to the muscular-winged genus Charaxes, we may congratulate Mr. Hoare that so many of them are in good condition. The following is a list of the species : — 1. AMAURIS WHYTEI Butl. A single perfect male example. 2. MELANITIS SOLANDRA Fabr. One female. 3. EURYTELA HYARBA, Var. ANGUSTATA Allriv.

To my mind it belongs to the intermediate form, and I think conclu- sively proves that A. asema is only a form of A. violarum. 21.

The seasonal differences appear to be slight in this species : the male seems to differ only in the better marked border to the secondaries in the wet-season, and the female in its smoky suffusion sometimes accompanied by a white belt across the primaries ; but at all seasons there seems to be a certain amount of variation even in these characters, though the clouded females do not, apparently, occur in the dry season. A male with very dry characteristics and labelled with Mr. Marshall's dry sign ^O was taken on the 26th March, and much wetter forms in Apr1!, when a wet male and dry female were taken on the same day. It seems to me that these facts are clearly in favour of my view that the seasonal forms of butterflies existed originally as simple variations, and were subsequently accommodated to seasons which afforded them most protection. Thus the males of A. ccddarena, which show no striking seasonal differences, and which would be hardly more conspicuous at one season than another, are inconstant in their seasonal characters, whereas if the white-banded, smoky female appeared in the dry season it would probably be very conspicuous. It may be questioned as to what advantage a protected Butterfly, such as an Acrcea, could gain by being inconspicuous. Although the species of this genus are said to be not only offensive, but elastic and difficult to kill, it is certain that many are permanently maimed by birds and reptiles which (presumably) seize them for the first time, or have not become satisfied of their inedibility.

H. durvasa is the extreme wet-season form of the species ; H. lalage (typical) is also a wet-season phase, probably appearing at the end of the rains ; H. pseudolalage is a smaller form, probably occurring at the commencement of the dry season ; and H. argyridina is a true dry-season phase. 13.

In this, the typical group, the primaries show little tendency to falcation at apex, the sexes are usually very dissimilar, and the colouring of secondaries below varies seasonally from ochraceous or yellow to pearl whitish. 1.

Kheil's illustration agrees well with one of our male examples ; but in his description he calls the upper-surface coloration hoary greyish, and he states that it belongs to the T. celestina group, in which (as is well known) the upper surface is pale chalky bluish. The figure, being a photo- graph, distinctly proves that " T. mata " is not a Tachyns , but a male Catophaga, and therefore that it is not nearly related to T. celestina, the dusky spot on the primaries being placed between veins 3 and 4, not between 4 and 5 ; and my opinion is that it is merely a feebly marked (perhaps dry- season) discoloured male of C. agave. I believe Staudinger's Tachyris agatha to be a variety of the female. The Tachyris fnaculata of Grose-Smith (compared with C. agave) appears to me to be closely related to Huphina acrisaj Boisd, of the Genus Catophaga. 396 3. Catophaga urania. c?.

I take the representative of the extreme wet-season phase to be that in which the male has the secondaries and apex of primaries below butter-yellow and the female a bright daffodil- yellow above, with the secondaries and apex of primaries below bright ochreous. Flying with this form C. neombo is obtained (an intermediate phase), in which the female is milky white, the male below with the secondaries and apex of primaries sericeous cream-coloured, varying to pale ochreous, and the female with the same parts pearl-white ; of the Genus Catophaga. 398 the dry form is represented by 0. albino, and Rouxii, in which the dusky border of the male primaries is either almost wholly absent or is reduced to a slender abbreviated black marginal line, and the female differs from G. neombo in the reduction of the black markings on the upper surface. Whether C. albino, is really a distinct species from C. paulina can only be finally settled by breeding from the egg ; the C. lets = darada form runs C. neombo rather close in both sexes. 12. Catophaga Wardii. Catophaga Wardii, Moore, Journ. As. Soc. Beng. Hi. p. 43 (1884). Nilgiris, Mysore, Rangoon. B. M. What I take to be wet-season males of this species resemble females of G. neombo in the character of the upper surface. I am not sure that two females without locality standing next to the male of this species in Hewitson's collection do not represent the wet-season phase of the female, the secondaries and apex of primaries below being deep orange ; but they may be merely unusually large examples of female G. lankapura. I think G. Wardii is a good species, distinct from G. paulina. 13. Catophaga cynisca. $ . Tachyris cynisca, Wallace, Trans. Ent. Soc. ser. 3, vol. iv. p. 375 (1867).

I consider this as probably the male of the wet phase and Dr. Holland's female as belonging to the same phase. S. Schombergi from Borneo and S. auran- tiaca from the Sula Islands probably represent the dry phase, which will doubtless be found in the Celebes also.

[Concluded from p. 401.] Group 4. TACHYRIS, Wall. The largest group in the genus, containing species of tolerably uniform outline, though differing considerably in coloration : the first and most typical species resemble the earlier forms of Saletara in the coloration of the males, whilst their females much more nearly resemble those of Catophaga ; then we meet with a series of bright scarlet or orange insects, gradually changing to species with the upper surface white and brown-bordered. In nearly the whole of the species the dark outer borders on the under surface of the wings are regular in outline, and in most of the white species the seasonal forms seem to be characterized by the width of these borders in the males and the amount of white on the upper surface of the females, the dry-season males having narrower borders and the dry-season females being marked with broad white patches *. 1.

The male varying above from brick-red to bright orange, the veins of primaries, and sometimes the veins on apical area of secondaries, dusky ; the apex and outer margin of primaries sometimes with a soft graded brownish border : under surface much more ochraceous, without markings, the centre of primaries more orange than the remainder of the under surface. Expanse of wings 72-77 millim. The female varies above from ' bright orange, through mixed ochreous and tawny, to pure white with dusky basal area and spotted black-brown outer border (as in I\ nero and allies) ; below also the wings vary from bright ochreous to ochreous and white commingled or to tawny and ochreous primaries with white subapical streak and pearl-white second- aries clouded with sandy greyish ; the ordinary markings (corresponding with those of the upper surface) more or less defined. Expanse of wings 59-66 millim. Palawan and Labuan. Ten examples, B. M. I cannot regard this as a variation of any known species ; the primaries of the male are more acute than in T. domitia and the under surface unmarked, whilst the female is ex- tremely variable, but has not at all the character of T. zam- loanga (T. domitia ? ), but more nearly resembles T.figulina (T. *nerOj var., ? ) ; its small size and invariably paler colour readily mark it as a different species. 11.
