64 LEPIDOPTERA HETEROCERA 
36. GENUS EUXENA, WARREN 
Euxena 1). Warren, Novit. Zool. Vol. 3, p. 365 (18906). 
Characters. — Face smooth. Palpus moderate, rather stout, second joint rough-scaled, third 
joint in gf small. Tongue developed. Antenna in g* almost simple 2). Pectus and femora hairy. 
Hindtibia in cf dilated with hairpencil, all spurs present. Abdomen not crested. Frenulum fully 
developed. Forewing with costa arched, apex squared, termen stronglv crenulate, convex, oblique, 
cell short, DC incurved, SC! free, SC? normal, M! separate; hindwing with termen crenulate, excised 
between R! and R?, cell short, C very shortly approximated, then rapidly divergimg, SC? short-stalked 
with R!, M! with R?. 
Early stages unknown. 
Distinguished from the preceding and following genera by the shorter cells, with consequent 
stalking of the radials of hindwing; also from Dooabia by hindwing-shape and from CAlorodontopera bv 
the simple cf antenna. 
Type of the genus : Euxena crypsichroma, N'arren (1896). — 
Geographical distribution of species. — Malay Peninsula to Borneo, ? Philippines.

37. GENUS CHLORODONTOPERA, WARREN 
Chlorodontopera. Warren, Proc. Zool. Soc. Lond. p. 351 (1893). 
Characters. — Face smooth. Palpus moderate, rather stout, second joint with rough projecting 
scales beneath, third joint small in gf, slightly rougher-scaled than normal, moderate in Q. Tongue 
developed. Antenna in gf bipectinate to four-fifths, the branches varving in differing species, in Q 
lamellate. Pectus and femora hairy. Hindtibia in c dilated, with strong hair-pencil, in both sexes with 
all spurs. Abdomen very slightly 'crested 3). Frenulum fully developed, in Q strong and compact. 
Forewing with costa nearly straight, apex roundlv prominent, termen strongly dentate anteriorly 
(excised between R! and R?), crenulate and very oblique posteriorly, cell about one-half, DC inbent, 
SC! from cell, anastomosing with C and SC?, SC? normal, R! well separate, R? above middle, M! separ- 
ate; hindwing with termen dentate, strongly excised between R! and R'*, cell nearly one-half, DC deeply 
inbent, SC? separate, R? from near R!, M! separate (Pl. 1, Fig. 1l). 
Early stages unknown. 
1) Not preoccupied by Zxenznws, Le Conte, 1870. 
2) 1f issudsafa really belongs to this genus, sometimes bipectinate 
3) We have seen few really good specimens, but believe that, as in. /ga£h£a, the crests are sometimes wanting ; in any case they have hardly 
generic significance.
