white hairs. There are also capitate smaller hairs on the upper part of each 
segment. _ 
The larva, about half-grown, was described as “‘Head yellow. Other 
segments pale brownish-yellow. A ‘narrow dorsal, latero-dorsal, and spira- 
cular reddish stripe. Legs pale yellow, prolegs and claspers dark. Hairs 
white, except the short clubbed hairs which are black ”’°(°). 
The full-grown larva “is about 7 mm. long, cylindrical, rather stout, the 
segmental interstices well marked. Legs and prolegs long and slender ; pale 
greenish-yellow. Head unicolorous, very pale, transparent greenish-yellow ; 
mouth-parts darker. Other segments pale greenish-yellow ; a narrow darker 
green dorsal line; each segment with a large but ill-defined, pinkish-red, 
latero-dorsal spot, the series of these spots forming an interrupted longitudinal 
line. Two conjoined latero-dorsal tubercles emit a very long white hair 
directed upwards and a shorter white palmate hair directed upwards and 
forwards ; a supraspiracular tubercle emits a brown palmate hair directed 
upwards and forwards ; two conjoined subspiracular tubercles emit a short 
white hair directed forward and a long white hair directed downward ; there 
are also one or two latero-ventral tubercles emitting white hairs. The whole 
surface of the segments is also closely studded with shoit white clubbed 
secondary hairs ’’(6). . 
The larve feed on the leaves of pumpkin, eating small holes in them 
and not feeding in from the margin. In the case of pigeon-pea and other 
pulses, the larva eats into the flower-buds and pods, but never goes fully 
inside. The clothing of spines and hairs probably serves a protective 
purpose, since this larva feeds on hairy leaves and pods and is both in 
colouring and pilosity assimilated to the surface it is on; it is sluggish in 
movement and clings tightly where it is openly exposed upon the leaf or 
pod. ; 
Pupa. Pupation takes place as follows:—The fullgrown larva spins 
silk upon the leaf or pod over a surface about 10 mm. by 8 mm. 
and then rests upon this, the anal prolegs firmly fixed in the end of it. The 
skin splits in front, and slips backwards along the body ; on the underside 
of the eighth abdominal segment is a distinct bunch of curved hooks (cremastral 
pad), which engages in the silk as the larva wriggles ; the hind end is then 
freed from the larval skin and the bunch of stiff recurved hairs on the eighth 
segment acting as a fixed point, the anal end by wriggling fixes the terminal 
bunch of hooks in the silk. The pupa is thus fastened by two points ; its 
anterior half is free and can be raised till it is almost at right angles to the 
fixed abdomen.
