43. B. iievadoiise tHke. — Form rather broad, moderately convex ; color 

 varying from dark brown to nearly black, slightly feneous, shining, the elytra 

 usually with an ill-defined basal spot and another submarginal one about one- 

 fourth from apex pale, the latter sometimes extending slightly transversely to- 

 wards the suture. Head as wide as the thorax at apex : palpi piceous; antennse 

 scarcely one-half as long as the body, piceous, the first joint more or less rufous. 

 Prothorax subcordate, rather more than one-half wider than long, as wide at base 

 as apex, slightly rugose at base; apex nearly truncate ; median line distinct, ab- 

 breviated before and behind ; transverse impressions rather feeble; basal impres- 

 sions broad, deep, bistriate ; sides with the margin narrowly reflexed, arcuate in 

 front, oblique, not or at most obliquely sinuate behind ; hind angles slightly ob- 

 tuse, but not rounded, carinate. Elytra less than one-half wider than the thorax, 

 oblong-ovate, finely striate, very finely at sides and tip : strife finely but distinctly 

 punctate to behind the middle, the five inner entire, the fifth slightly grooved at 

 tip; third stria with the first dorsal puncture about one-third from base, the 

 second about one-fourth from apex ; intervals nearly flat. Legs varying from 

 dark rufous to piceous, the femora usually darker. Length .18-.23 inch ; 4.5- 

 5.75 mm. 



This species resembles the next quite closely. From consaagum- 

 enm, however, it may be recognized by the thorax with the sides not 

 at all or at most obsoletely sinuate behind, and the more finely striate 

 elytra with usually an ill-defined basal spot. From striola, with 

 which it is sometimes confused, it seems abundantly distinct by the 

 characters given above. 



It occurs in Nevada^ California and Oregon. 



44. B. c«n<*rtngiiineuiii n. sp. — Form slightly robust, moderately convex ; 

 color black, more or less ?eneous, shining, the elytra with a submarginal spot 

 about one-fourth from apex, extending more or less transversely towards the 

 suture, or sometimes the entire apex pale. Head as wide as the thorax at apex ; 

 palpi piceous; an ten nse about one-half the length of the liody, piceous, the first 

 joint usually paler. Prothorax subcordate. about one-h;ilf wider than long, as 

 wide at base as apex, scarcely rugose at base : apex nearly truncate; median line 

 distinct, abbreviated in front and sometimes also behind ; transverse impressions
