128 NYMPHALID^. NYMPHALIN^E. ARGYNNIS. 



At Aden this form also varies, examples occurring in which the hindwing is suffused 

 vith white on the disc, its mode! being the true Danais dorippus of Klug. This variety of 

 Hypolimnas has been separately described by Mr. Butler as H, ahippoides * It occurs in the 

 Victoria Nyanza, Africa, as well as in Aden. 



"Larva purple-brown, numerously covered with minute white spots, cylindrical, thickest 

 towards the middle ; head armed with two erect rugose spines, the segments with three 

 dorsal rows of branched pale spines and three lateral rows of shorter spines. Feeds [in 

 Ceylon] on Abiitilon, Abelmoschus, &c." In Calcutta it feeds on Forlulaca quadrifida, and 

 Colonel Lang has reared it on Portulaca oleracea. " Pupa purple-brown, thick, abdominal 

 segments tubercular, head obtusely pointed, thorax convex." {l\foo>e, 1. c.) I can see no 

 resemblance between the larva of H. misippus and that of Danais ckrysippus, although 

 Boisduval is said to have seen some. 



//. vrsippus appears to be almost as universally met with in India as is Danais ckrysippus, 

 which is the model of the I. Form of its female. The apex of the forewing on the under- 

 side being ochreons will at once distinguish the males of this species from that sex of 

 H. boUna, though in size and general style of markings the small rainy season brood of the 

 latter resembles it somewhat closely, but it always has tlie apex of the forewing black beneath. 

 The figure shows the upperside of a male from Kulu, and of a female I. Form from 

 Ceylon in the Indian Museum, Calcutta.

 •♦ Head, rather broad, hairy. Eyes, nearly round, smooth. Palpi, porrect, slightly 

 ascending, divergent, projecting considerably beyond the head : the first and second joints 

 clothed with scales and long setiform divergent hairs ; the third joint with scales, and more 

 or less appressed hairs. First joint subcylindric, curved, about one-fourth the length of the 

 second • second joint slightly curved, much swollen beyond the middle, then narrowed towards 

 the apex, which is truncate ; third joint very small, acicular, about one-fourth the length of 

 the second. Antennce rather short, terminating in an abrupt pyriform club. Thorax, rather 

 stout, rounded, oval. Abdomem, moderate, about two-thirds the length of the inner margin 

 of the wintT. Forewing, trigonate ; \!a^ costal margin rounded; the outer about two-thirds 

 the len<Tth of the costa, sometimes slightly concave, sometimes nearly straight, often rounded ; 

 inner about equal in length to the outer margin, nearly straight. Costal nervtire stout, ex- 

 tending about three-fifths of the length of the wing ; subcostal slender, sometimes emitting 

 its first and second nervules near together before the end of the cell, the third at less than half 

 the distance between this and the apex, the fourth rather more remote from the apex than 

 from the third ; sometimes emitting its first nervule before the end of the cell, its second [after 

 the end of the cell] at about an equal distance from the first and third, its fourth nearer to 

 the third than to the apex. Upper disco-cellular nervule very short, sometimes almost wanting ; 

 middle curved inwards, longer [? shorter] than the lowe<-, which is nearly straight, and 

 anastomoses with the third median nervule at some distance from its origin. Hindwing, 

 obovate ; the margins about equal, all rounded. Prcecostal nervure simple, slightly curved, 

 directed outwards ; discoidal nervule appearing to be a third subcostal nervule. Discoidal cell 

 closed by a slender disco-cellular, sometimes flexuous, sometimes nearly straight. Foreleg.s, 

 of the male, fringed with long delicate hairs ; tibia smooth, rather shorter than the femur ; 

 tarsus %h.ox\.tx than the tibia, one- jointed, subcylindric, tapering towards the apex. Of the 

 female sc3.]y, slightly fringed with hairs ; tibia fully as long as the femur, smooth, slenderest in 

 the middle ; tarsus shorter than the tibia, smooth, five-jointed ; the first joint twice the length of 

 the rest combined ; the second barely one-fourth the length of the first ; the third one-half
