dark rufous, the head more plceous, the elytra feebly clouded at the 

 sides and near the scutellum, the abdomen blackish, the sixth segment 

 and tip of the fifth rufous; antennae dusky, pale at base; head 

 rather sparsely, the pronotum finely and not very closely punctured, 

 the eyes large, the antennae short, not as long as the head and pro- 

 thorax, very stout, fusoid, the tip narrower than the sixth joint which 

 is twice as wide as long; prothorax nearly as in tezana; elytra rather 

 less than twice as wide as long, though obviously shorter than the 

 prothorax, finely, rather distinctly, closely punctured ; abdomen as in 

 texana but with the punctures very sparse ; mesosternum similarly broad 

 between the coxae, the metasternal process still shorter and more 

 rounded ; first joint of the hind tarsi distinctly shorter than the next 

 three combined. Male with the apex of the sixth tergite having about 

 ten small equidistant teeth, the median four smaller and more acute 

 than the three at each side. Length 4.8 mm.; width 1.5 mm. North- 

 eastern States of America fasicornis n. sp. 



Sixth tergite of the male truncate at tip 4 



4 — Teeth of the sixth male tergite even and equal in size or nearly so toward 



the middle g 



Teeth of the sixth tergite uneven, the medial tooth broadened, forming a 

 small lobe < 7 



5 — Median punctate part of the mesosternal process very wide, subparallel 



toward tip, the latter broadly arcuate and usually extending somewhat 

 over the apex of the extremely short and broadly rounded metasternal 

 process, with the sides of the process less advanced posteriorly, its 

 width, at the apical width of the process in front of the latter, being 

 about four times that of the coxal grooves. Body moderately stont, 

 shining, blackish -piceous, the elytra more rufous, except toward the 

 sides posteriorly and broadly in the region of the scutellum ; abdomen 

 black, the apical margin of all the segments dull rufous; antennae black- 

 ish, pale toward base, the legs pale as usual; head small, distinctly less 

 than half as wide as the prothorax, finely, sparsely, the latter finely but 

 rather closely, punctured; eyes large; antennae nearly as in the pre- 

 ceding species but less stout, the sixth joint slightly wider than the apical 

 but scarcely twice as wide as long ; prothorax two-thirds wider than long, 

 strongly narrowed anteriorly, the sides and base broadly rounded with 

 the basal angles obliterated as usual; elytra nearly twice as wide as long, 

 shorter than the prothorax, the suture nearly three-fourths as long as the 

 latter; abdomen only moderately narrowed from base to apex, the former 

 as wide as the elytra, the punctures coarse and very sparse ; hind tarsi 

 rather distinctly shorter than the tibiae, the first joint obviously shorter 

 than the next three combined and equal to the last two. Male with the 

 comb of the sixth tergite composed of about twelve short triangular 

 teeth, the two or three at each side generally smaller than the others. 

 Length 4.8-6.0 mm.; width 1.2-1.65 mm. New York (Catskill Mts. and
