126 LEPIDOPTERA HETEROCERA 
in Q much elongated. Tongue developed. Antenna in gf bipectinate to nearly two-thirds, with rather 
short branches, in Q nearly simple. Pectus hairy. Hindtibia with all spurs developed. approximated; 
in c dilated with strong hair-pencil and moderate terminal process. Abdomen not crested. Frenulum 
in G' from before slight basal expansion, in Q wanting. Wings hyaline, iridescent. Forewing with costa 
arched, apex moderate, termen rounded, waved, moderately oblique, cell short, less than two-fifths at 
discal spot, but greatly produced at apex and considerably at posterior angle, DC therefore extremely 
inbent (angled at discal spot), SC! free, SC? long-stalked, but arising before SC*, R! connate or short- 
stalked, M! long-stalked; hindwing with apex and termen rounded, termen weakly subcrenulate, tornus 
pronounced, cell short, DC? somewhat inbent anteriorly, oblique posteriorly, C appressed to cell to 
about one-half, then rapidly diverging, SC? long-stalked, R? from somewhat above middle, M! long- 
stalked. 
Early stages unknown. 
Evidently related to PArudocentra, but distinct in the hyaline wings, subcrenulate termen of 
hindwing, extremely inbent DC of forewing and long stalking of M! of both wings.

Chrotochlora. Warren, Novit. Zool. Vol. 12, p. 317 (1905). 
Characters. — Pectus hairy. Femora scarcely hairy. Hindtibia in cf with all spurs. Abdomen 
not crested. Frenulum slender, from before basal expansion. Forewing triangular, costa straight, 
somewhat arched distally, apex rather acute, termen entire, oblique, straight, tornus rather pronounced, 
cell less than one-half, DC? deeply incurved, SC! from cell, running into C, SC? short-stalked with SC*», 
running close to C -- SC!, perhaps with contact at a point, R! connate, R* from above middle of DC, 
M! connate; hindwing with apex rounded, termen rounded, tornus squared, cell less than one-half, 
C approximated to cell to nearly one-half, rather gradually diverging, DC? incurved, SC? very. shortly 
stalked, M! connate. 
Early stages unknown. 
We have given all the informations available on this genus, without being able to express any 
definite opinion on its status. It was founded on a single, headless specimen which, so for as we know, 
remains unique. The scaling, though smooth, is thick, and some points in the venation therefore remain 
uncertain.
