186 LEPIDOPTERA HETEROCERA 
135. GENUS LATHOCHLORA, WARREN 
Lathochlora. Warren, Novit. Zool. Vol. 7, p. 9o (1900). 
Characters. — lace smooth. Palpus (in cf unknown) in 9 moderate, slender, third joint 
exposed, smooth, somewhat elongate Tongue present Antenna in Q rather short and thick, lamellate. 
Hindtibia with terminal spurs only Abdomen not crested. Frenulum in Q wanting, costal expansion 
marked. Wings smoothly scaled. Forewing broad, with costa strongly arched, apex acute, termen 
strongly gibbous in middle, the gibbosity culminating beyond R?, thence sinuous and very oblique, cell 
short, DC? curved, DC? arising distad, SC! long-stalked with SC?», quitting little before SC*, 
SC? stalked to far beyond SC*. R! just separate, R? from above middle of DC, M! connate; hindwing 
with apex rounded, termen produced at R! and R?, with excision between, anal angle pronounced, cell 
short, DC slightly angled at origin of R?, C anastomosing with cell at a point near base, rapidly 
diverging, SC? stalked, M! short-stalked. 
Early stages unknown. 
The above characterization is drawn up from Warren's single (and not quite perfect) type Q, 
and we know of no other example. The genus appears to be a valid one, and there can be little doubt 
that the cf will prove to possess a frenulum. It is very probable, as Warren suggests, that the genus is 
related to the preceding, though the shape of the wings is much more closely that of BatAycolfodes or 
Chloroparda.

Hyalorrhoé Warren, Novit. Zool. Vol. rr, p. 21 (1904). 
Characters. — Face smooth. Palpus moderate to long, slender, second joint usually reaching 
beyond frons, shortly scaled, third joint smooth, often greatly elongate. Tongue present. Antenna in gr 
bipectinate to about two-thirds, with moderate branches; in Q dentate or shortly bipectinate. Pectus 
slightly hairy. Femora glabrous. Hindtibia in gf somewhat dilated, with hair-pencil and terminal 
process, all spurs developed. Abdomen not crested. Frenulum in G' slender, from before basal expan- 
sion. Wings more or less hyaline. Forewing with costa slightly arched, apex rather acute, termen 
oblique, gently curved, cell one-half or rather less, DC incurved, oblique posteriorly, SC! from cell, 
anastomosing strongly with C, SC?* long-stalked, SC? given off after SC», R? separate (short-stalked 
in stigmatica and auster), R? from above middle, M! well separate; hindwing with apex usually rounded 
or subcrenulate, termen somewhat toothed at R!, usually a little excised between this and D", cell 
short, DC? incurved, strongly oblique posteriorly, C anastomosing with cell at a point, or closely 
appressed, diverging rather gradually at first, SC? long-stalked, R? very characteristic, M! separate. 
Early stages unknown.
