ous, scattered, round punctures mostly above the middle. Scutum 

 with its notauli and its anterior medial groove continuous or nearly so. 

 Metanotum with shallow median impression, densely punctate, its 

 largest punctures nearly equalling those of the scutellum. Legs with 

 femora and tibiae of last two pairs bright red ; major calcarium of 

 hind tibia widest at bend near middle; groove of hind basitarsus 

 deep, and nearly as long as the joint; outside spines of basitarsus 

 stoutly lanceolate, irregular, from three to seven in number including 

 one at apex. Tegula with outer edge thin and somewhat upcurled, 

 Propodeal areola keystone to vase-shaped in outline, from two to two 

 and one-half times as long as wide; carina not bordered by grooves 

 or transverse ridges, frequently lacking in part; medial carina some- 

 what broader than lateral carina, and complete ; inclosed area apically 

 sometimes reticulate. Lower portion of sides of propodeum minutely 

 striate, not clearly separated from the upper rugose area. Posterior 

 aspect of propodeum glossily setulose at center ; narrow medial carina 

 complete to the transverse carina, except for occasional interruptions. 

 First tergite usually with a small, elongate median patch of dense, 

 fine punctures ; preapical band not differentiated. First sternite with 

 a lateral groove on posterior half; anterior half with sparse punc- 

 tures. Tergites with minute, nonsetigerous punctures in a broken 

 line just before the apices; impunctate apex at the middle from five 

 to six times the width of largest bordering punctures. Pygidium 

 densely reticulo-punctate on basal three-fifths; apex wrinkled, out- 

 side wrinkles converging along the margin; impunctate area very 

 faintly shagreened at the sides ; impunctate emargination very small. 

 Length, 7.5 to 11.5 mm. 



Mc^e. — Vertex with primary punctures everywhere of third-degree 

 density. Front with carina and impunctate stripe; primary punc- 

 tures densely grouped on lower front, preocellar area with punctures 

 irregularly spaced on upper half, with several interspaces as broad 

 as an ocellus; secondary punctures very fine, and more numerous 

 than primaries on lowest third, ascending medially slightly higher 

 than near the eyes. Antennocular distance greater than width of 

 antennal fossa. Clypeal extension with the apical width four-fifths 

 the clypeoantennal distance; disk convex; apex shallowly emar- 

 ginate, with narrow but well-defined impunctate margin, apical 

 points upturned. Pronotum with its transverse carina produced 

 into a prominent angle laterally; primary punctures very small, 

 obscurely outlined, and largely of sparse third-degree density; sec- 

 ondary punctures widely distributed over punctate area, but diffi- 

 cult to distinguish from the primaries. Side striate, with anasto- 

 mosing rugae anteriorly, but without a distinct groove across the 

 center. Mesepisternum with small, fairly well outlined punctures
