preceding together; basal half nearly globular; apical half 

 conical, subulate. Pa/pt ytWow, second joint clavate; third 

 globular; fourth fusiform, pointed at both ends, sharply 

 acuminate, as long as the first and second antennal joints 

 together. Prothorax longer than wide, median sulcus want- 

 ing; median fovea deep, connected with the lateral ones by an 

 arcuate sulcus each side; lateral sulcus sharp, separating the 

 convex disk, from the convex marginal lobe; behind the fovea 

 and basal margin is a small carina, and on each side a puncti- 

 form fovea. Elytra convex, scarcely wider across the shoul- 

 ders than the base of the prothorax; suture one-fourth longer; 

 the width across the tip is one-half greater than that of the 

 prothorax; sides divergent, arcuate behind the middle; 

 shoulders low, not prominent; sutural lines not close, straight, 

 punctate; discal lines short, not reaching one-fourth the 

 length; disk extremely minutely and faintly punctulate. 

 Abdomen nearly as wide as the elytra; basal segment more 

 than one-third as long as wide; carinae short, separated by 

 one-third the segmental width; lateral depression ample. 

 Tarsi with the second and third joints equal in length, l^ last 

 antennal joint with a basal tooth; last ventral with a round 

 shallow impression. $, last dorsal acutely produced behind. 

 Habitat. British Columbia. 



B. occiDUUS, Casey. Brownish-red; slender, polished; pubes- 

 cence coarse. Length 2 mm. Plate X., Fig. 85. 



Head impunctate, broadly convex, eyes small, foveae large, 

 deep, and nude, frontal lateral tubercles large. Antennce as 

 long as the head and thorax together, with the ninth joint 

 slightly transverse, the tenth strongly transverse; the last twice 

 as wide as the ninth and as long as the three preceding ones 

 together, truncate at the base, oblong-oval, obliquely acumi- 

 nate. Prothorax as long as wide, with a deep, nearly entire 

 median sulcus. Elytra with narrow shoulders, obsoletely 

 punctulate. Abdomen as wide as the elytra, the basal segment 

 slightly longer than one-third its width, with three equal 

 transverse pubescent basal foveae, and without carinse. l^ last
