pressed throuorhout the width, the terminal membranous hj^poglottls 

 almost one-third as long. 



The description of this very distinct species is taken from the 

 male, the eighth ventral segment being very deeply incised, the 

 seventh broadly cusped. It should be placed near ciispidatus. 



B. agonilS n. sp. — Slender, moderately depressed ; sides parallel ; pice- 

 oiiH, elytra rufo-testaceous, broadly and indefinitely clouded with darker casta- 

 neoiis toward the suture and base ; abdomen black ; legs throughout and coxae 

 pale flavate ; antennse brownish-rufoiis. Head very slightly narrower than the 

 prothorax, feebly shining, densely, coarsely granulato-reticulate, not distinctly 

 punctate ; eyes rather large and prominent, the setse very short and sparse ; 

 antennal prominences strong, the epistomal suture slightly impressed ; vertex 

 not tuberculate, but having a large rounded rather deeply-impressed puncture ; 

 antennse moderate, second joint one-third longer and more robust than the 

 third, four to six much shorter, submoniliform, six to eight rapidly wider ; 

 outer joints strongly transverse, eleventh ovoidal. scarcely as long as the two 

 preceding together. Prothorax as wide as the base of the elytra, about one-third 

 wider than long ; sides in anterior two-thirds parallel and almost straight, then 

 convergent and arcuate to the base which is transverse ; basal angles very 

 obtuse and rounded, lateral rounded and entirely obliterated, apical right and 

 narrowly rounded ; apex transverse ; disk feebly shining, densely, coarsely 

 granulato-reticulate, rather finely but distinctly, very sparsely and somewhat 

 unevenly punctate, the pubescence very sparse but rather long ; median groove 

 veiy fine and feebly impressed. Elytra very slightly longer than wide, about 

 two-thirds longer than the prothorax, very finely, feebly and sparsely punc- 

 tate, the punctures sejiai-ated by about three times their own diameters, but 

 much closer than those of the pronotum ; sides nearly parallel ; pubescence 

 very sparse and short. Abdomen as wide as the prothorax, shining, rather 

 finely, densely and strongly reticulate throughout, finely and v(!ry sparsely 

 punctate, the under surface more densely so and distinctly reticulato-rugulose. 

 Length 4.5 mm. 



Utah. 



The mentum is broadly and deei)ly impressed especially toward 

 base, and the anterior angles of the epistoma are distinctly tuber- 

 culate in the male. 



A very distinct species which should be associated with cnspi- 

 datus. 



B. iiieptlis n. sp. — Rather slender and convex, piceous ; elytra pale 

 flavate, the suture narrowly dusky, more broadly so toward base ; legs and 

 antennse flavate, the latter infuscate toward apex ; head finely, strongly granu- 

 lato-reticulate, feebly shining ; i)ronotum feebly reticulate throughout, except 

 along the median line where the surface is polished and the reticulation obso- 

 lete, rather strongly shining ; abdomen polished but distinctly, evenly reticu-
