callosity either side of middle. Scutellum very transverse; sides nearly straight,
oblique; apex rounded, feebly emarginate at middle. Elytra with sides nearly
strn.ight to middle then feebly areuate to apices, which are separately rounded;
basal half with nine or ten more or less irregular rows of coarse, deep punctures
between humeral carina and suture and five or six between carina and side of eiytra,
just beyond middle these become very obsolete and disappear before apex; humeri
rounded, the apex of which is obliquely truncated, with a small tubercle at posterior
end of truncnture, thence with a short carina to middle. Prosternum simple; pro­
coxae prominent, tumid posteriorly, and with a long, slender uncus on inner side;
profemora transversely rugose dorsally and ventrally. Fifth stemite slight.ly longer
than fourth, rounded apically. Antennae about as long as body, beneat.h moderately
fimbriate on first, third, and slightly on fourth segments; scape robust, short, nearly
capitate, scabrose basally and finely, densely punctate apically.

whit.ish fascia and in the tawny tomentum on apical third a small whitish macula
placod slightly laterally instead of a single, irregular, large, whitish macula Oll each
elytron; humeri at angle much less obliquely truncate and not tuberculate on pos­
terior end of truncature.
