TRE COMMON BUTTERFLIES OF TKE PLAINS OF INDIA. 78o 



spiracular expansion to the spiracle of segment 2. The colour of that of fusca 

 is grass-green ; of amhareesa and leucocem golden red-brown ; the former dark, 

 the latter light but the two, other^vise, practically identical, 

 c. Larvje with second segment not white ; surface densely 

 hairy, opaque ; head furred ; colour glaucous-green 

 or glaucous whitish-green or red-brown . . Genus Caprona. 



a\ Head with a bare patch below vertex of each lobe 



A single species ransonnettii. 



h\ Head with three spots of brown hairs in a hne across 

 upper part of face, the other hairs all white ; no 



bare patches Genus Odontopti- 



lum. 



A single species . . angulatum. 



c\ Head with no spots of a different colour and no 



bare patch ; white or yellow Genus Gomalia. 



A single species albofasciata. 



The larvEe of Caprona, Odontoptilum cannot be mistaken for anything else, 

 having the head strikingly long-furred ; that of Gomalia has the head much 

 more obscurely furred, but is much smaller, slighter. The pupse of the two 

 larger are, of course, also, much larger and are green and light yellowish soiled 

 with brown, green on thorax and head with large, prominent, brownish spiracular 

 expansions to segment 2 and marked with black ; with a prominent boss or 

 beak between the eyes ; that of Qomalia more or less concolourous green with 

 no beak or black spots and with the expansions smaller, lower, rounder. The 

 food of the larvae are sapindaceous for Odontoptilum, sterculiaceous for Caprona 

 and malvaceous for the third. 



C. — Larvae never with bright colours ; always opaque-looking, white or green- 

 ish-white ; covered with erect, minute and simple hairs more or less 

 densely ; head with erect covering of hairs or not, round or triangular. 



a. Larva, pure, opaque-white, hairs not at all promin- 



ently visible ; head broadly cordate, thin, nearly 



naked . . . . . . . . . . . . Genus Tapena. 



Only one species . . . . . . . . . . hampsoni. 



b. Larva opaque-glaucous-green, covered with com- 



paratively long, white and brown, erect hairs ; 

 • head round, thick and densely furred on upper 

 part . . . . . . . . . . . . Genus Hesperia. 



Only one species . . . . . . • . . . galba. 



c. Larva opaque-yellowish-green, more yellow than 



green, the covering of hairs minute, somewhat 

 sparse ; head obcordate-triangular, very finely 

 velute . . . . . . . . . . • • Genus Cupitha. 



Only one species purreea. 



d. Larva opaque-white with a black collar on segment 



2 ; hau'-covering invisible ; head roundly heart- 

 shaped without, however, any sinus, naked, 



oranc^e Genus Matapa. 



Only one species . . . . . . • • • • O'^iO'- 



e. Larva really red and white in colour, but quite 



white with a dense covering of long, confused, 

 excreted threads of a waxy nature ; head trian- 

 gular, thick ; a very large larva . . • • Genus Gangara. 

 Only one species . . . . • • • • • • thyrsis. 



The pupa of Gangara can be distinguished from all others by the enormous 

 length of the curled, free end of the proboscis, as well as by its large size ; that 

 of Matapa by being a small reproduction of that of Gangara with the free end
