a very pale shining greenish-white colour. In size it is about 0°47 mm. long 
by about 0°32 mm. broad and 0°28 mm. high, a transverse section thus being 
oval. The newly-hatched larva is whitish, with a black head and, long black 
dorsal hairs ’’(°). 
The full-grown larva is about 6°5 mm. long and about 1°25 mm. broad, 
cylindrical, slightly tapering towards either extremity, segments distinct, pale 
yellow slightly tinged with greenish ; head pale yellow with some faint pinkish 
blotches and bearing longish hairs, these hairs especially evident on the front 
and some of them being knobbed apically ; other segments with a distinct 
pinkish-brown mid-dorsal stripe and with interrupted lateral stripes, ventral 
area pale greenish-yellow ; tubercles rather protuberant, each bearing a tuft 
of hairs of different lengths, the post-spiracular tubercle only having a single 
hair ; short secondary hairs scattered over segments ; spiracles protuberant, 
tubular ; five pairs of equally developed, rather long, pale yellow prolegs. 
The larva feeds upon Oxalis sp., pupation taking place upona leaf of the

This is a remarkably widely-distributed species ranging through the 
whole of West, South and East Africa, the Seychelles and Maldive Islands, 
Ceylon, throughout India, Burma, the Philippines, Japan, Sumatra, Java, “P. A a ee 
throughout Australia, New Hebrides, Tonga Islands, and the West Indies. 
This distribution has perhaps heen caused to some extent by human agency.
