The egg has been described as "of a smooth elongate-oval shape and of 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 r25 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 havihg 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 upon a leaf of the foodplant. The pupa is pale apple-green with whitish hairs as shown in figure. SPHENARCHES CAFFER, ZELL. (PLATE II.)

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, '^Jl^Q, throughout Australia, New Hebrides, Tonga Islands, and the West Indies. This distribution has perhaps been caused to some extent by human agency.
