<$ 2 • Termen of fore wing more concave near the middle than 

 in D. plexippus. Upperside : fore wing tawny darkening towards 

 the costal margin ; costa narrowly and the apical third of the 

 wing black ; one or two white spots beyond and above apex of cell 

 followed by a preapical, white, oblique bar, with one inner and 

 two subterminal white spots below its lower end ; lastly, a more 

 or less complete series of terminal white spots and dots of varying 

 size. Hind wing : ground-colour paler ; termen somewhat narrowly 

 black, with an incomplete series of white spots ; three black marks 

 on the discocellulars. Underside similar, paler ; ground-colour of 

 the hind wing and a triangular area at apex of fore wing ochra- 

 ceous ; white markings and spots more distinct. Antennae black ; 

 head and thorax black spotted with white ; abdomen ochraceous 

 above, whitish below. Male secondary sex-mark in form 1. 



Exp. <$ 2 70-84 mm. (2-75-3-3"). 



Hab. A widespread species throughout our limits, and found in 

 Southern Europe, Syria, over a great part of the Ethiopian Eegion, 

 through Arabia, Persia, and Afghanistan. Eastwards it extends 

 to China and through the Malayan Subregion to Sulu and the 

 Celebes. 



Larva. Bluish grey, the sides yellow, each segment with five 

 transverse black lines and two yellow patches, the head with a 

 yellow patch anteriorly and three black lines, the 3rd, 6th and 

 12th segments each with a pair of fleshy black filaments, crimson 

 at the base. Feeds on Ccdotropis gigantea (Madar, Hind.) and 

 various Asclepiads. 



Pupa : dichroic, some green, others pale pink or wax-white, 

 beautifully marked with golden spots and a black gold-bordered 

 line near the tail. 



Var. alcippus, Cramer, and var. alcippoides, Moore, only differ 

 from the typical form in having the hind wing suffused more or 

 less with white. In the long series of these two forms in the 

 British Museum collection a regular gradation can be traced from 

 specimens having just a touch of white on the disc of the hind 

 wing to specimens which have part of the cell and seven-eighths 

 of the disc beyond white. 



Dimorph dorippus [D. dorippus, Klug (D. Mugii, Butler)] has 

 been found, by Col. Terbury and other observers, in cop. with 

 typical chrysippus. The points of difference between it and 

 chrysippus are as follow : — No black apex nor oblique white bar 

 on fore wing ; the latter, however, sometimes indicated ; sub- 

 terminal and terminal series of white spots on both fore and hind 

 wing fewer in number, occasionally absent altogether. As in the 

 typical form, a variety of B. dorippus is found with the hind wing
