46. GENUS CHLORORITHRA, BUTLER 
Chlororithra. Dutler, Ill. Het. Coll. Brit. Mus. Vol. 8, p. 106 (1859). 
Characters. — l'ace smooth Palpus rather long, second joint strongly rough-scaled, reaching 
beyond frons, third joint smooth, in cf moderate, in Q rather long. Tongue developed. Antenna in gr 
bipectinate to about two-thirds, in Q simple. Pectus hairy. Hindtibia in cf dilated with long pencil of 
hairs, a very short terminal process, in both sexes with four unequal spurs. Tarsi spinulose. Abdomen 
not crested. Wings smoothly scaled, iridescent. lrenulum fully developed. Forewing with costa very 
slightly arched, apex rather acute, termen oblique, verv slightly waved, cell nearly one-half, DC? deeply 
incurved, SC! free, SC? normal, R! well separate, R? from near R!, M! separate; hindwing with apex 
rounded, termen convex, waved, slightly sgibbous about R?, cell less than one-half, DC? incurved, 
C approximated to cell to nearly one-half, then strongly diverging, SC? separate, R? from close to R!, 
sometimes almost connate, M! connate or very short-stalked with R? (Pl. 2, Fig. 9). c genitalia very 
distinct from any other studied, uncus a long rod, with curved socii, gnathos terminating in a tooth, 
harpe with a scobinated projection towards the base of the inner margin, penis pestillate, narrow; on 
the eighth sternite there is a rounded plate, emarginate on the upper edge, from which protrude a pair 
of scobinated arms; this species has long coremata. 
Early stages unknown. 
This genus is likely related to the preceding, which it resembles in its smooth-scaled, iridescent 
wings, and in various other characters.

Antenna nearly two-thirds, in c bipectinate to about one-half, with moderate, decreasing branches, 
a long apical portion nearly simple. Pectus densely hairy. Femora hairy. Hindtibia in C dilated with
