108 AMERICAN COLEOPTERA. 



Philadelphia, Pennsylvania. Two examples so labeled in 

 Dr. Fenyes' collection. 



The type is a male having the posterior margin of the sixth 

 ventral obliquely beveled in its middle third ; the beveled 

 area apparently membranous, about four times as wide as 

 long, arcuate in front, nearly straight behind. This species 

 resembles semifermginetis but is somewhat smaller, with 

 much less coarsely punctate head and thorax. Gravidus 

 agrees well in most respects but it too is larger, the abdo- 

 men is said to be parallel, and the sexual characters are 

 quite different. 



B. piceus n. sp. 



Black, prothorax piceous, tip of abdomen, legs and antennae rufous, 

 the latter slightly dusky apically. Head and prothorax densely finely 

 granulato-reticulate, the former dull, the latter feebly shining ; elytra 

 shining, abdomen finely reticulate and shining. Second antennal joint 

 about one-half longer than the third and not very much shorter than 

 the third and fourth together, tenth nearly one-half wider than long. 

 Head with a few fine and feeble widely scattered punctures posteriorly, 

 vertex evenly broadly convex, the occipital puncture small ; epistoma 

 simple ( 9 ) , suture fine, somewhat impressed ; eyes rather small and 

 not very prominent. Prothorax very slightly wider than the head, 

 not much wider than long, sides straight and parallel in apical three- 

 fourths, thence convergent and straight to base ; lateral angles very 

 obtuse but distinct, basal angles less obtuse and not well defined, apical 

 right and rather narrowly rounded ; punctuation fine and sparse, 

 median line fine but well impressed. Elytra scarcely wider at base 

 than the prothorax, as long as wide, the sutural length subequal to 

 that of the prothorax, sides a little divergent, punctuation rather close, 

 the punctures moderate in size. Abdomen gradually wider posteriorly, 

 finely very sparsely punctate above, rather coarsely and much more 

 closely so beneath, especially toward the base. Prosternal sutures dis- 

 tinct and moderately oblique, the hypomera evidently impressed along 

 the outer margin ; coxal fissures a little shorter than the adjacent 

 hypomeral width, almost completely closed. Length 3.9 mm. 



California — Pasadena and Oceanside (Fenyes). A speci- 

 men from Colorado collected by Prof. C. F. Baker is appar- 

 ently identical. 



A somewhat small and inconspicuous species belonging to 

 the semiferrugineus group, to none of the members of which 

 it seems very closely related. In general appearance it is
