COMMON BUTTERFLIES OF THE PLAINS OF INDLi. 681 



triangular, sloping and thickened ; body surface dull and transversely line 

 with a row of minute white tubercular spots between every two lines. 

 Colour green with a circular, dorsal, large spot on each segment 4-12 which is 

 deep violet becoming light towards the red-tinged yellow centre, bordered 

 black : the yellow centre developing only when the larva is full-grown and the 

 black border is narrowly flanked on each side with white; sometimes these spots 

 are red. The belly is bluish-white ; processes are green, light brownish at 

 extremities, the terminal spines black with white tips. The side processes are 

 set with spines all round, each spine ending in a short hair. Dorsal mark of 

 segment 4 is small and transversely oval near front margin, that of segment 

 12 slightly larger, longitudinally oval, but still small compared to the others, 

 L : 32mm. without processes, 45mm, with : B : Gmm. without, 23mm. with 

 processes. 



Pupa. — The pupa is oc the same shape as that of Doplila ; the dorsal pyramid 

 of segment 7 well developed as also the two head-points ; cremaster very strong 

 with three lateral tubercular small knobs, the hinder ones close together ; ven- 

 trally there is a row of 6 smaller knobs along each ridge ; the end of cremaster 

 is set with a dense brush of short, black, hooked hairs : it is truncated triangu- 

 lar in shape, thick. Surface of piipa shiny, smooth segmental divisions not easily 

 visible. Spiracles of segment 2 plain, oval, slightly convex, rather large, whitish ; 

 the others also fau'ly large, oval, slightly convex with the central slit plainly 

 visible, light-green in colour. Colour of pupa green, top of ridge of segment 

 7 broadly gold with the apex and each extremity touched with black, its front 

 edge borders thinly black ; a black spot on each shoulder, each head-point tip 

 and dorsally on hinder margin of thorax ; a golden semi-circle tipped with 

 black behind touching each spiracle of segment 3. L : 21mm. ; B : 11mm, at seg- 

 ment 7 ; at shoulders, 8mm. ; at head-points, at tips, : 4mm.; H: 10-5mm. at 

 segment 7, 



Habits. — The egg is laid singly on the underside or u})perside of a 

 leaf ; the young larva is whitish. Larva lives on the midrib near base 

 of upperside of leaf on a bed of silk ; walks haltingly, is sluggish in its 

 movements, eats from side of leaf, preferring old leaves to young 

 ones and hardly ever finishes eating a whole leaf wandering about a 

 good deal. The pupa is attached, as usual, to the underside of the 

 leaf firm] T. The imagines have the flight already described for others 

 of the genus and are fond of sitting on paths and other open spaces 

 in the sun and do not often light on leaves ; they are most active 

 in the heat of the day and both are e(iually plentiful where they 

 occur : they do not take long flights. They are insects of the plains 

 and do not occur near the sea-shore or much below 1000' above 

 sea level ; they are found also in forest couutrv where the land is
