?. Length 11-12 mm. Head elongate, eye orbits subparallel. Clypeus — 
long, shining, convex, with a broad median sulcus which widens apically, 
its punctures very coarse but separated, finer and closer in the sulcus. Su- 
praclypeal area duller, densely punctured marginally. Cheeks densely punc- 
tured, a little shiny, bearing white pubescence. Malar space concave, very 
polished, basally with a few punctures, much elongated, being one and 
one-half times as long as broad. Front dullish, closely and distinctly punc- 
tured, its pubescence short, erect, grayish white. Vertex dullish, finely 
densely punctured and with larger punctures scattered about, its pubes- 
cence long, erect, and sparse, mainly black. Antennae shining black, joint 
3 decidedly longer than 4, 2+3, being twice as long as 4, the proportion 
being 4:6:5. Prothoracic spine rudimentary, a mere bump. Pubescence 
of thorax above rather long, erect, pale fulvo-ochraceous to ochraceous- 
gray, much mixed with black, the latter color in a dense scutellar fringe, 
but none on postscutellum. Punctures of mesothorax rather coarse, deep, 
and much crowded, somewhat sparser on a shinier disk. Scutellum coarse- 
ly punctured, densely so posteriorly, postscutellum opaque and roughened 
by excessively close and rather fine punctures. Superior face of meta- 
thorax defined by an angulation, the shining rectangular pits rather nar- 
row. Enclosure funnel-shaped, the bowl narrow, slightly shiny, trans- 
versely plicate and laterally ridged, the neck rather long and narrow, con- 
cave, polished and impunctate. Lateral areas of posterior plate opaque, 
minutely punctured and indistinctly reticulated, clothed with long, erect, 
pale pubescence. Mesopleura dull, closely and coarselv punctured, their 
pubescence silvery, as it is on the whole under surface also. Tegulae pice- 
ous. Wings slightly darkened, nervures and stigma dark reddish. brown. 
Legs black, clothed with grayish white pubescence, the tibiae, especially 
the posterior pair, with numerous short black bristles among the pale ones, 
the inner apices of the tarsal joints with ferruginous tufts. Anterior coxae 
simple. Tibial spurs pale, the hind ones not pectinate. Claws ferruginous 
and toothed medially. Basal joint of hind tarsi slender, two and one-half 
times as long as broad, median joints of similar proportions. Abdomen 
suboval, stout, shining, the first segment with long, erect, fairly dense, 
grayish white pubescence which forms conspicuous lateral fringes, its basal 
truncation polished and impunctate, its convexity with fine well-separated
