26 LREPIDOPTERA HBIEROGERA 
Group 1I 
6. GENUS NEOBALSBIS, Nov. GEN., PROUT 
Neobalbis, nov. gen, Prout. 
Characters. — Build robust. Frons protuberant, densely scaled. Palpus moderate to longish, 
first joint long-scaled beneath, second joint stout, rough-scaled above, moderately long-scaled beneath, 
third joint smooth, in Q rather long. Tongue developed. Antenna in both sexes virtually simple. Pectus 
densely hairy. Femora hairy. Hindtibia with all spurs. Metathorax not crested. Abdomen with small 
paired dorsal crests. Frenulum fully developed. Forewing with costa slightly arched, apex moderate, 
termen oblique. crenulate, cell somewhat less than one-half, discocellulars incurved, SC! from cell, 
anastomosing with C, SC? from well down the stalk of SC??, anastomosing at a point with SC!, 
"Riseparate, R? from slightly above middle of discocellulars, M! separate; hindwing with costa short, 
apex rounded, termen long, strongly crenate, inner margin long, cell scarcely two-fifths, DC? incurved, 
C approximated to cell for some distance near base, then sharply diverging, SC* separate, R? charac- 
teristic, M! well separate. 
Early stages unknown. 
The evolutionary importance attaching to the point of origin of SC? of the forewing necessitates 
the erection of this genus for a few species which are evidently in the direct line of descent from 
Avrchaeobalbis, agreeing absolutely therewith in facies, and scarcely differing structurally except in the 
position of that vein. It would, indeed, be possible to merge our new genus with its relatives 77erochroma 
and Actenochroma, which, however, have virtually lost the abdominal crests, and have other features of 
their own.

NorE. — H»ypochroma sinapiaria, Poujade, and Gnofhos crassipunctata, Alphéraky, which we have 
not seen, but have referred with a query to ArcAaeobalbis, may equally well belong to the present genus.
