of the humeri are distinctive and the ostiolar canal is continued 
into only a very short suleus, quite different in form from that 
in Trichopepla. In conjunction with the above characteristics, 
the presence of the sinuous, irregularly furcate and somewhat 
anastomosing venation of the wing membrane is worthy of men- 
tion.

Body elongate ovate, distinctly narrowed anteriorly and posteriorly. 
General color pale yellowish to brownish, rather closely and coarsely but 
irregularly punctured with black; each puncture contains a white hair. 
Entire body covered with short white hairs which are denser and longer on 
the head and pronotum. Head narrow, elongate, darker on either side of 
the pale median lobe which is distinctly raised and becomes suddenly 
broader between the eyes and extends thus to the base of the head; lateral 
lobes confluently punctate, a little longer than median lobe; entire head 
thickly covered with long white hairs. Antennae short, black, a little pale 
at incisures, the apical segment longest, all the segments with long, stiff 
white hairs. Rostrum short, extending just behind midcoxae, the two 
apical segments black, the basal segment shorter than the pale, high buc- 
eulae enclosing it. Pronotum rather regularly, coarsely punctate, the an- 
terior half conspicuously pilose; antero-lateral margins entire, sinuate, a 
prominent tubercle at anterior angles and a prominent process somewhat 
curved posteriorly at the lateral angles just before the humeri which are 
rounded and a little elevated. Scutellum regularly, coarsely punctured 
with black, the punctures finer towards apex which is moderately nar- 
rowed; a broad Y-shaped ruga begins at the basal angies of the scutellum 
and continues for two-thirds the distance towards the apex where the stem 
of the Y becomes obsolete. Hemelytra narrower than abdomen, coarsely 
punctured, the costal margin impunctate, raised a little near base; apex 
of corium distinctly emarginate; membrane whitish, the nervures more or 
less sinuous and anastomosing to some extent; bordered with milky white. 
Tergum blackish, densely punctured, the outer posterior margin of each 
segment yellowish, the rest of connexivum fuscous. Venter pale yellowish 
to brownish, heavily punctate with blackish, each of the punctures bearing 
a fine white hair; the punctures aggregated somewhat along the sides be- 
low the spiracles to form a more or less distinct blackish longitudinal line; 
outer apical angles of segments expanded into tooth-like projections which 
thorax coarsely punctured and with long fine hairs. Legs yellowish, heavily 
give the edge of the abdomen a serrated appearance. Side pieces of
