40 THE LEPIDOPTERA OF CEYLON. 



Family CHALCOSIID^. 



Wings long, ratlaer broad : forewing with a discoidal veinlet emitted "witliin the 

 cell ; two submedian veins. Antennee thickly bipectinated to tip in male, less pecti- 

 nated and more or less flabellate at tip in female. Flight diurnal. 



Larva short, thick ; tubercular ; with two or three short fine hairs arising from 

 each. Pupa in a densely-silken cocoon. 



Genus TRYPANOPHORA. 



Trypanopliora, Kollar, in Hiigel's Kaschmir, iv. 2, p. 457 (1844). 

 Wings partly diaphanous : forewing elongated, narrow, apex acute, exterior margin 

 oblique ; costal vein thick at the base ; first subcostal emitted at one-fourth and 

 second at about one-tenth before end of the cell, third trifid, the radial being thrown 

 off from below third close to the base; discocellular inwardly oblique; emitting a 

 slender pseudo-vein within the cell ; cell long, extending three-fourths the wing ; four 

 median branches at nearly equal distances apart, the lowest being emitted at nearly 

 one-third before end of the cell ; two submedian veins much recurved : hindwing 

 narrow ; apes convex, exterior margin very oblique, slightly concave in middle ; 

 costal and subcostal confluent from near base, and joined to apex of wing ; no sub- 

 costal branch ; discocellular bent outward in the middle, emitting a slender pseudo- 

 vein within the cell; radial from the angle ; cell extending four-fifths the wing; four 

 median branches at nearly equal distances, lower being emitted at two-fifths before 

 end of the cell ; two very slender submedians and an internal vein. Thorax rather 

 stout, abdomen extending half length beyond hindwings, ovipositor exserted in 

 female ; antennse long, bipectinated in male, minutely bipectinated and thickened at 

 the tip in female ; head flat in front, palpi very small ; proboscis long ; legs smooth.

 Trypanophora taprobanes, Walker, Catal. Lep. Het. Brit Mus. ii. p. 435 (1854). 



Forewing bluish purple-brown, with a broad subapical transparent macular 

 patch : hindwing blue, the anterior border purple-brown. Head and legs purple- 

 brown ; antennas purple-blue. 



Expanse ? 1^ inch. 



Larva dark purple-brown, short, thick ; third to sixth segments with two dorsal 

 and two lateral rows of short sparsely-haired tubercles, the lower lateral tubercle on 

 second segment longer and clavate ; a lateral yellow blotch on tenth and eleventh 

 segments. Pupa pale reddish-ochreous ; in a yellowish dense silky cocoon.
