Face smooth. l'alpus in moderate, second joint shortly but densely scaled

moderate branches. Pectus hairy. Hindtibia in o somewhat dilated, all spurs present, the terminal 
the shorter. Abdomen with four dorsal crests of curved hairs. Frenulum in cf developed, no appreciable 
basal expansion to hindwing. Forewing with costa straight to near apex, then arched, apex moderate, 
termen oblique, especially posteriorly, cell less than one-half, DC incurved, SC! free, SC? stalked to 
beyond SC*, R! connate, M! approximated ; hindwing with apex rounded, termen subcrenulate, slightly 
toothed at R'and R?, tornus pronounced, cell short, DC? oblique, DC? hardly oblique, C shortly 
approximated to 5C near base, then rapidly diverging, SC? stalked, M! short-stalked. 
Early stages unknown. 
Apparently close to the preceding and following genera, so that the Q frenulum may be assumed 
to be wanting or vestigial; that of the c is as in ApgatAofsis. 
Type of the genus : CAloromianta ferruginata, Warren (1896).

Rhomborista. Warren, Novit. Zool. Vol. 4. p. 44 (1897). 
Characters. — l'ace smooth. Palpus moderate to rather long, second joint shortly but densely 
scaled, third joint smooth-scaled, in gt short, in Q variable. Tongue present. Antenna short, in c 
bipectinate to about two-thirds with rather long branches, in Q nearly simple. Pectus hairy. Hindtibia 
in gf dilated with hair-pencil, but without terminal process, all spurs present. Abdomen with small, 
narrow crests. Frenulum in cf rather strong, but not very long, arising from before a basal expansion 
of hindwing, in Q wanting. Forewing with costa slightly arched, apex moderate or rather acute, termen 
oblique, varying from very gently curved to ventricose, cell rather short, DC somewhat sinuous, 
usually slightly angled at origin of R?, SC! free, SC? stalked to far beyond SC?, R! connate or separate, 
M! separate; hindwing with apex rounded, termen crenulate, with projecting teeth at R! and R?, or 
smoother with slighter teeth, tornus pronounced, cell rather short, DC? obliquely curved, DC? arising 
markedly distally, curved or rather strongly oblique, C approximated to cell near base, then rapidly 
diverging, SC? stalked, M! very shortly stalked, connate or approximated. 
Early stages apparently undescribed. 
A very close relative or C/hloromianta, but with definite basal expansion of hindwing, and. with 
very different, slighter dorsal crests. 
Type of the genus : I'homborisla devexata (Walker) — Comibaeaa devexata, Walker (1897).
