I63. GENUS CHLORACTIS, WARREN 
Chloractis, Warren, Novit. Zool. Vol. 2, p. 88 (1895). 
Characters. — Face smooth. Palpus in gf slender, moderate, smooth-scaled (Q unknown). 
Tongue present. Antenna in c bipectinate with short branches. Hindtibia in c scarcely dilated, but 
with a terminal process fully one-third as long as tarsus, all spurs well developed. Abdomen not crested. 
Wings thinly scaled, subhyaline. Forewing with costa gently arched, apex acute, termen slightly 
incurved to R?, here elbowed, thence very oblique, tornus not sharp, cell less than one-half, DC deeply 
inbent, SC! from cell, anastomosing with C, SC? normal, R? from above middle, M! approximated 
at origin to R?; hindwing with termen produced to a tail at R?, tornus pronounced, inner margin long, 
cell less than one-half, DC? strongly inbent, C rather shortly approximated to cell near base, rapidly 
diverging, SC? rather long-stalked, R? from very near R!, M! very short-stalked. 
Early stages unknown. 
Related to the preceding, but differing in the palpus, the form of discocellulars, shape of 
wing, etc.

I64. GENUS CACOOCHLORIS, Nov. GEN., PROUT 
Cacochloris, nov. gen. Prout. 
Characters. — lace smooth. Palpus moderate or longish, rather stout, second joint rough- 
scaled, third joint small or (ocAhrea) slightly elongate. Tongue short. Antenna short, in both sexes 
bipectinate with moderately long branches. Pectus somewhat hairy. Hindtibia in Cf not dilated, in 
both sexes with all spurs. Abdomen not crested. Frenulum wanting in both sexes, basal expansion of 
hindwing well marked. Wings thickly scaled. Forewing with costa straight, apex rather acute (less so 
in ochrea), termen oblique, straight anteriorly, curved posteriorly, cell about one-half; DC inbent, 
oblique posteriorly, SC! from cell, anastomosing strongly with C, SC? coincident with (wvidula) or 
stalked with (ochrea) SC!, R! short-stalked, M! separate; hindwing with apex rounded, termen somewhat 
rounded, tornus rather prominent, cell short, DC? usually rather incurved, C anastomosing with cell 
at a point (uvidula) or rather more (ochrea), gradually diverging, SC? stalked, R? normal, M! separate. 
Early stages unknown.
