4I. GENUS LIMBATOCHLAMYS, ROTHSCHILD 
Limbatochlamys. Rothschild, Novit. Zool. Vol. r, p. 540 (1894). 
Characters. — lace densely scaled. Palpus in C quite moderate, second joint rough-scaled, 
third joint small, concealed. Tongue present. Antenna in c bipectinate to near apex with extremely short 
branches. Pectus and femora strongly hairy. Hindtibia in gf not dilated, with four well-developed 
spurs. Tarsi spinulose. Abdomen not robust, not crested. Wings ample. Frenulum fully developed. 
Forewing with costa moderately arched, apex acute, somewhat falcate, termen oblique, slightly convex 
in posterior half, cell nearly one-half, DC? rather strongly oblique posteriorly, SC! from cell, anast- 
omosineg shortly or connected by. very short bar with C, SC? normal, R! from close to SC??, M! separate ; 
hindwing with apex rounded, termen slightly waved, tornal region somewhat produced, inner margin 
long, cell nearly one-half, DC? inbent, strongly oblique posteriorly, C approximated to cell to almost 
one-half, not very rapidly diverging, SC? separate, R? from much above middle, M! separate. 
Early stages unknown. 
Probably related to Tanaorhinus, etc.; may possibly really have more to do with the non-crested 
members of Group II, but the smoother scaling of the wings, their shape, and their amplitude relatively 
to the body have induced us to regard it as belonging here.

Characters. — lace densely scaled, sometimes slightly protuberant. Palpus moderate to long, 
second joint reaching well beyond frons (longer in 9 than in c), denselv 
scaled, but without the long-spreading hairs of typical Z7tPparchus, third joint 
in cf moderate or rather long, in Q very long, smoother-scaled, cylin- 
drical (Fig. 5). l'ongue developed. Antenna moderate, in cj bipectinate, 
typically with rather short stout pectinations to little bevond one-half, in 9 
simply pubescent. Pectus densely hairy. Legs stout. Femora strongly hairy. 
Hindtibia in cf dilated with hair-pencil, in both sexes with all spurs. Tarsi 
spinulose. Abdomen not crested. Frenulum fully developed. Forewing with
