?. Length 8 mm. Shining black, stoutish. Clypeus shiny, convex, not 
sulcate, its punctures large and fairly close but not striate, sparsely clothed 
with erect, pale hairs. Supraclypeal area well punctured. Face closely 
and rather finely punctured, clothed with short, dense, erect, grayish white 
pubescence. Antennae short, black with the flagellum brownish beneath 
beyond second joint, joint 3=5 but decidedly longer than 4, the proportion 
being 3:2:3, the median joints shorter than wide. Vertex with sides very ~ 
shiny, finely double punctured, clothed medially with sparse, long hairs, 
pale with a few blackish ones intermixed. Cheeks shiny, finely sparsely 
punctured, sparsely white hairy. Malar space very short, one-ninth as 
long as broad. Prothoracic spine reduced to a mere pointed angulation. 
Mesothorax with the anterior half, a broad line down each side and a 
narrow line along posterior margin with coarse and deep, close but sep- 
arate punctures, the space enclosed by these areas forming an unusually 
large, polished, perfectly impunctate disk. Entire scutellum rather coarsely 
and fairly closely punctured on a shiny surface, postscutellum with small, 
close punctures, opaque. Metathorax with a well-defined superior face 
which has the usual shining pits, squarish medially, laterally poorly de- 
fined and narrow. ‘Enclosure funnel-shaped, basally with a narrow trans- 
verse depression, elsewhere concave, narrow, smooth, and highly polished, 
nowhere dull. Lateral faces of posterior plate shiny, coarsely but shal- 
lowly punctured. Sides of metathorax dullish or slightly shiny, minutely 
punctured and ridged, and with scattered, larger punctures. Mesopleura 
with coarse, close, striate punctures. Pubescence of thorax grayish white, 
thinner and paler below, above conspicuously mixed with black and dark 
brown hairs, these densest on a scutellar fringe, the disk practically devoid 
of pubescence. Tegulae shining blackish. Wings hyaline, stigma dark 
brown, nervures brownish fuscous to black. Legs moderately stout, black, 
their pubescence densest on the posterior femora and tibiae, all silvery 
white except that on inner side of tarsi, which is golden brown, the basal 
joint of hind tarsi three times as long as broad. Claws medially toothed, 
ferruginous, the tibial spurs large and blackish, the outer posterior ones 
with about a dozen long, coarse teeth, the inner one finely pectinate, the 
anterior coxae not spined.. Abdomen suboval, shining, the first segment 
polished and subimpunctate, the second segment indistinctly punctured, the 
punctures becoming fairly dense on the margins, the third and following
