CH.EEOCAMPA. 57 



ochreous-white specks from the first somite to the end of the eleventh. The stigmata are 

 (lark, outlined in blaek, aud hardly visible. Legs crimson. 



Blown larva 3^ inches. Feeds on the same Rubiacea as C theylia. 



Chserocampa vinacea. (Plate CLVII. fig. 26 & Plate CLXXV. figs. 2, 2 a.) 



Expanse 21? inches. 



Male. Closely allied to C. rafflesii, Butl. ; the fore wing longer and slightly narrower 

 and suffused with lilac ; the lateral streak on head and thorax is almost pure white, as also 

 are the autennse and fore legs, and the coloration of the insect generally is much brighter. 



Larva (adult). Pale vinous brown; a very narrow medio-dorsal black line from first to 

 foui'th somite; a pair of paler dorso-lateral streaks on the thoracic somites; the fourth and 

 fifth somites bear paired dorso-lateral ocelli, wMch are oval in shape and ochreous, outlined in 

 black and centred with brown, in the first ocellus dark brown with an ochreous streak, the 

 second with crimson streak ; some dorsal and lateral black striaj on sixth to tenth somites ; 

 the stigmata are white outlined in black and conspicuous ; the fourth to terminal somites 

 liave scattered white lateral specks ; the horn shorter than in C rafflesii, straight and pointed, 

 dark brown with a white tip ; paired dark antero-lateral streaks from its base forming a 

 V-mark ; anal somite with paired pale streaks joined posteriorly. 



Blown larva 3^ inches. Feeds on several sjiecies of Impatiens. 



Pupa. Dull fawn-colour, minutely speckled with brown ; the stigmata on alxlominal 

 segments enclosed in a round black spot. 



The larva of this species belongs to Weismann's second group of Chcerocampa, while 

 those of C. theylia and rafflesii belong to the third group. 



The images of C. theylia, rafflesii, and vinacea are almost indistinguishable, and whether 

 we have here three species breeding true, or the larvae are affected by some condition of life in 

 shape of horn as well as colour and number of ocelli, we have no evidence to show. 



Chserocampa butus, Cram. (Plate CLXXV. fig. 10.) 



Sphinx butus, Cram. Piqi. Krot. ii. p. 58. 



Larva (adult). Pale green, thickly speckled with darker spots and stria; on fifth to tenth 

 somites ; the fourth somite swollen, bearing a pair of large oeellated spots, green, Ijordcred 

 with yellow above aud pink below, and with a central linear white spot ; a pale lateral line 

 with dark upper edge from anterior edge of fifth somite to root of horn ; stigmata edged with 

 pink; horn purple, stout and curved. Legs pink ; claspers green. 

 Feeds on Vitis. 



There is a variety in which the green colour is replaced by brown, with the exception of 

 the oeellated spots, which remain olive-green. In some specimens there are traces ol 

 irregular diagonal stripes between the spiracles. 



The young larva has a long thin horn recurved at tip.
