Typelocality. Georgia [ U.S.A.].

Type repository. Museum of Comparative Zoology. Harvard University, Cambridge, MA ( U.S.A.) (type not examined).

Redescription. Length 3.0- 4.5 mm; oblong, moderately convex, weakly shiny; head and pronotum glabrous, elytra pubescent. Reddish-brown, head and pronotum somewhat darker; legs and antennal club ferruginous. Head with epistome moderately convex, finely microreticulate, almost evenly coarsely moderately closely punctured; clypeus slightly sinuate at middle, round at sides; rather thickly bordered, edge somewhat upturned, glabrous; genae round, sparsely ciliate, feebly but distinctly protruding from the eyes; frontal suture finely impressed; front with punctationsimilar to that of epistome. Pronotum moderately transverse, rather convex, dually subregularly coarsely punctured throughout; large punctures, twice larger than small ones, somewhat sparser on sides and on disc; small punctures almost uniformly scattered; lateral margins feebly arcuate, rather thickly bordered, edge glabrous; hind angles obtuse; base arcuate, thickly bordered. Scutellum narrowly elongate, roughly punctured on basal half. Elytra oval, epipleuralcarina glabrousand somewhatraised at shoulder; striae deep, rather coarsely notclosely punctured, crenulate; interstriae slightly convex, microreticulate so rather dull, irregularly biseriately roughly punctured; each puncture with a short recumbent hair. Hind tibiae superior apical spur slightly shorter than first tarsal segment; latter as long as following three segments combined. Male: pronotum somewhat more transverse, not narrowed frontwardly; metasternal plate somewhat more excavate and with distal punctures pubescent; aedeagus Fig. 44-45 . Female: pronotum somewhatnarrowed frontwardly; metasternal plate almost flat, glabrous.
