open curve ; this hinder margin of thorax has some shallow indentations just 

 in front of it dorsally, a single row ; the whole thorax (segment 3) is short ; 

 the cremaster is rather long, quite as long as segment 13 and is trapeze- 

 shaped, narrowing backwards, the hinder margin or extremity being very 

 distinctly concave, the lateral margins are thickened and run onto segment 

 13, the dorsal extensor-ridges are not prominent converging from somewhat 

 flattened extreme hinder corners forwards to front margin where they are 

 well separated, the suspensory booklets are between them at hinder 

 margin of cremaster and are ventral ; the ventral extensor-ridges are more 

 or less parallel, ending each in a little free point ; the antennge, as in aU 

 other members of the genus Colotis, end, flattened, at the apex of wing- 

 bulge. Spiracles of segment 2 hardly indicated ; others oval, colour of pupa, 

 very slightly raised, with a central, depressed line. Surface of pupa is irre- 

 gularly corrugated, under lens, by impressed lines, pitted also on abdomen, 

 the intersegmental membrane between segments 8, 9 and 9, 10 narrowly 

 exposed ; the lateral outline along wing somewhat prominent (the wings are 

 slightly expanded that is) from shoulders to end of wings ; the rounded 

 extremity of head-point or snout is smooth. Colour is that of fresh, dry 

 bone, somewhat livid ; lateral outline from shoulders to cremaster, above 

 spiracles on segments 8-12, narrowly light, this line on abdomen being brought 

 out by slight, dark shading above it ; a black dot laterally near front margin 

 of each segment, sometimes a larger dorsal one near hinder margin of seg- 

 ments 8 and 9 ; the spot on discocellulars of wings also black ; fuscous dots 

 showing at ends of veins of hindwings ; shallowly impressed similar dots 

 outside outer margin of antennse. The pupa is sometimes light green with 

 the lateral line faintly yellow ; there is sometimes an indication on head 

 and the succeeding two segments of a dark dorsal line. L : 19 mm ; B : 5 

 mm. at shoulders, the broadest part ; H : 6 mm at apex of wing-bulge ; B : of 

 abdomen at segment 9 : 3'5 mm. 



Habits. — The eggs are laid separately on the foodplant, generally 

 on an old leaf but sometimes on a dry twig or leaf-scar ; if on a 

 leaf, then indiscriminately on the npper or under surface or on the 

 edge ; one female was seen to lay 20 eggs in quick succession on a 

 single plant, coming to rest with her wings closed over her back at 

 each operation ; the noteworthy feature being the short time she 

 took over each act. This particular female was discovered flying or 

 rather fluttering along over the ground about 11 a.m. in the month 

 of August near Sholapur in the Bombay' Presidency; she was 

 followed up for about two hours carefully by two men in grass-land 

 with an open covering of small trees : Acacia arabica, Gaij]jaris 

 divaricata, Mimosa rubricaulis, Sandalwood, Neem, &c. She kept 

 much to the shade of the trees the tops of which (there were none of 

 them over 25 feet in height) she often explored ; often rested on the 

 ground with half-opened wings for ten minutes at a time ; until, 

 finally, she foiind what she wanted : the foodplant of the larva, up 

 to that time unknown. Upon this she immediately commenced 

 laying, and each egg was carefully collected and preserved for breed- 

 ing purposes. Afterwards, however, a number of larvae were also 

 found, some of them, a few, full-grown and nearly ready to pupate. 

 Three quarters of them were parasitized and produced ichnevimons ; 

 three eventually survived to the pupal stage. The males fly fast.
