Ataenius schwarzi.—Brown, 1928:307.

DESCRIPTION.—Length 3.7 to 4.9 mm; width 1.6 to 2.3 mm. Oblong, convex, shining, dark castaneous to piceous. Head convex, finely reflexed clypeal margin slightly angulate to subdentate but often appearing rounded each side of wide, moderate, median emargination, sides straight or weakly arcuate to right-angled genae; clypeal surface transversely, coarsely wrinkled, the wrinkles usually broken in part into elongate tubercles, front with transverse band of very moderate punctures separated in general by about their diameters; genae with four or five noticeable setae. Pronotum convex, three-fourths as long as wide, anterior angles obtusely rounded, posterior angles more broadly rounded, the slightly arcuate sides usually slightly sinuate, base strongly margined, edges fimbriate-crenate, the crenations weak, the setae moderately long, separated laterally by a little less than their length; surface with mixed punctures, everywhere with fine, evenly distributed punctures separated by one or two diameters and very coarse punctures unevenly distributed, mostly in the anterior and posterior angles with a few scattered across the base and above a smooth space at middle of sides. Elytral width about two-thirds the length, convex, sides slightly arcuate, humeri finely, weakly dentate; striae strong, the deep strial punctures slightly crenating the inner margins of the moderately convex intervals, surface with irregular, marginal row of minute punctures along each side, lateral intervals not different. Mesosternum shagreened, with very fine surface sculpture and extremely fine, short, decumbent hair, not strongly carinate between the coxae. Metasternum shining, midline fine, only moderately impressed, very finely punctate, with punctures generally separated by about two or three times their diameters, a little rough sculpture at extreme sides, metasternal triangle elongate and deepest along posterior margin. First visible abdominal sternum with fine posterior marginal line, remaining four sterna finely fluted along anterior margin, the fluting longer on successive sterna, that of middle sternum slightly longer at sides, of the 5th sternum longer at middle; surface almost impunctate at middle, a few coarse, shallow, setigerous punctures at sides; 5th sternum with a row of three or four close, moderate, more conspicuously setigerous punctures each side. Pygidium with smooth, apically wide lip, disc finely, scabrously eroded, with a few scattered, long hairs. Anterior femora with perimarginal groove, anterior and posterior margins bearing long, fine setae, surface shining, finely punctate, the punctures separated by two or more diameters; anterior tibiae broader than usual. Middle and hind femora smooth, shining, very finely punctate, three or four coarse setigerous punctures at knee, without posterior femoral line. Posterior apical tibial fringe, seven or eight rather short setae, short, triangular accessory spine and an intervening seta between spine and spurs. Posterior metatarsal segment shorter than long spur, longer than following three segments combined. Male pygidium much longer than that of the female.
