THE CANADIAN ENTOMOLOGIST. 303 



Cheeks shiny, finely sparsely punctured, clothed with long sparse white 

 pubescence. Vertex with long sparse hairs, pale and black intermixed, 

 occiput with a short, dense pale fringe. 



Prothoracic spine present, short and sharp. Mesothorax with small, 

 round, deep punctures, crowded but distinct anteriorly, along sides and 

 posteriorly well separated, a very few on a good-sized shining disc. Pleura 

 similarly but striately punctured. Scutellum with anterior one-third shin- 

 ing and impunctate, the remainder coarsely, sparsely punctured, 

 and with a median depressed line. Postscutellum densely punctured. 

 Superior face of metathorax fairly well defined, its pits shining, somewhat 

 irregular, longer than broad. Enclosure perfectly funnel-shaped^ shining, 

 the bowl convex, with a median and several lateral ridges, the neck concave 

 and perfectly smooth. Surrounding areas shiny, with sparse but very 

 distinct punctures. Pubescence of thorax white, tinged with gray above 

 and sparingly mixed with black on mesothorax and scutellar fringe. 

 Tegulse black, edged with testaceous. Wings subhyaline, nervures dark 

 brown, stigma paler. 



Legs stout, black except for apical tarsal joints, which are brownish, 

 clothed with short, dense, white pubescence, that fringing anterior borders 

 of intermediate and posterior tarsi short, stiff and black, that on under 

 surface of posterior femora and tibiae largely black. Basal joint of hind 

 tarsus three times as long as broad, and hind tibi?e very stout. Tibial 

 spurs short, dark testaceous, not distinctly pectinate. Claws ferruginous,' 

 medially toothed. Anterior coxae with very short blunt spines. Abdomen 

 stout, distinctly subconical, shining black, first segment subimpunctate, 

 or at most indistinctly and scatteringly punctured, second and following 

 segments indistinctly but rather closely punctured, the apical margins per- 

 fectly smooth and impunctate under the fasciae, which are broad and pure 

 white on segments 1-5. Basal segment with long, erect, white hairs on 

 the basal truncation, becoming shorter, sparser and subdepressed on the 

 convexity, and forming a short, dense fringe down the sides, uniting with 

 the apical fascia. The following segments have short scattered pale hairs, 

 becoming longer, denser and more bristly in a fringe just before the 

 fasciae, and also intermixed with similar dark ones on the last three seg- 

 ments, especially the apex. Ventral segment 5 deeply emarginate on 

 apical margin. Apical margin of first two segments and base of second 

 segment depressed and constricted.
