Larva .—The larva feeds in Ceylon on the flowers of the 
square-stemmed jungle vine (Vitis quadrangularis) so 
characteristic of the dry districts of that island. The 
following is a brief description made on October 20, 1908, 
from a living larva found at Hambantota :— 
Length 7 mm., stout, stoutest at about miil-length, decreasing 
rapidly anally ; head capable of retraction into or under prothorax. 
Fig. 3.—Dent, socotraiius. 
Incisions between segments distinctly marked. Colour a uniform 
pale-green ; head yellowish-brown and prothorax dark blackish- 
purple. Prothoracic legs pui-ple, other legs and prolegs pale-green ; 
legs and prolegs rather short and stout. To the naked eye no hairs 
are visible except two paii’s of short whitish curved hairs on the 
anal segment and a pair of short submedian hairs, directed forward, 
on each thoracic segment. Spiracles high-placed, about half-way up 
the side, fairly conspicuous from being outlined in a slightly lighter 
green tint than that composing the general colour of the larva.
