punctate area. Side of pronotum with numerous punctures along 

 the anterior borders and in a small depressed patch medially in 

 front of the tegula. Mesepisternum with a well defined premarginal 

 groove on its posterior slope. Metanotum with apical callosity 

 more or less densely beset with minute punctures, the largest some- 

 what smaller than those of the scutellum. Legs with major calcarium 

 of hind tibia uniformly tapering; hind basitarsus without a groove, 

 a group of two pricklelike spines on outside beyond middle but none 

 at apex. Tegula without impressed line on the outside but with a 

 short, incised line on lower inner margin. Wings moderately smoky. 

 Propodeal areola convergent, keystone-shaped, twice as long as 

 wide; lateral carinae with a bordering groove on the outside; median 

 carina broadening anteriorly, two-thirds the length of areola. Lower 

 portion of sides of propodeum polished, posterior half densely setulo- 

 punctate. Posterior aspect of propodeum with a few scattered 

 punctures on the upper margin; median carina developed on less 

 than lower half. First tergite with dorsal punctures dimpled, with- 

 out a preapical band, but with a deep preapical groove broadly over- 

 lapped dorsally. First sternite vaguely rugose, but lacking definite 

 primary punctures; lateral grooves on posterior half. Tergites 3, 

 4, and 5 with well defined marginal incised line, tergites 3 and 4 

 with dense secondary punctures on basal half, but lacking erect, 

 brown hairs. Pygidium not carinate, sparsely and irregularly punc- 

 tate, without well-defined impunctate emargination of punctate basal 

 portion; impunctate apex with many wrinkles converging below, 

 and strongly shagreened. Length, 9.5 mm. 



Male. — Vertex with primary punctures back of ocelli of first 

 degree density. Front with primary punctures moderately large, 

 of first-degree density medially below middle and laterally to vertex, 

 of uniform second-degree density in preocellar region; primary 

 punctures displaced almost completely on lower third by dense 

 secondary punctures which extend upward in the interspaces as far 

 laterally as medially, about half way to lowest ocellus. Anten- 

 nocular distance much greater than width of antennal fossa. Clyp- 

 eal extension with its apical width four-fifths the clypeo-antennal 

 distance; apex shallowly emarginate without inpunctuate margin. 

 Flagellum with a narrow fuscous stripe beneath. Pronotum with 

 primary punctures large, deep, round, of first-degree density, and 

 evenly distributed; a few widely scattered secondary punctures. 

 Side of pronotum with a series of overlapping rugae extending from 

 ventral corner one-third to three-fourths distance to alar angle; 

 primary punctures extending down from dorsum along entire length 

 of the plate. Mesepisterum with moderately large, round, primary 

 punctures of vague outline, mostly of second-degree density; secon-
