tainino; tbe apex, the fifth represented by a feeble groove at tip, the third with 

 two dorsal punctures, the first about one-third from base, the second about one- 

 third from apex ; intervals flat. Beneath black, shining. Legs rufo-testaceous. 

 Length .15-. 17 inch ; 3.75-4.25 mm. 



A very singular little species, and one with affinities in several 

 directions. The eighth elytral stria being distinct from the margin, 

 the dorsal punctures on the third stria, and the humeri rounded, it 

 seems best placed next to nigrum. The thorax is, however, less 

 quadrate than in that species and all the stride of the elytra are ab- 

 breviated behind. When we compare it with B. semistriatum the 

 resemblance is very striking, but the peculiar arrangement of the 

 dorsal punctures in the last-named species excludes any association 

 with it. 



It occurs in California. Specimens have been sent to me from 

 Dunsmuir (Wickham), the Pomona Mountains (Fall), and Santa 

 Rosa ( Ricksecker). 



23. B. loiigiiliiin Lee. — Form elongate, scarcely depressed; color black, 

 more or less teueous, shining. Head slightly narrower than the thorax at apex ; 

 palpi black ; antennse about one-half as long as the body, dark piceous or black. 

 Prothorax about one-half wider than long, slightly narrower at base than apex ; 

 apex truncate ; median line deep, usually abbreviated at each end ; transverse 

 impressions moderately distinct, the jjosterior deeper; basal impressions deep, 

 bistriate ; sides with the margin very narrowly reflexed, arcuate in front, feebly 

 sinuate behind ; hind angles sub-obtuse, but not rounded, finely carinate. Elytra 

 less than one-half wider than the thorax, oblong-ovate, deeply striate, the first> 

 second, third and seventh strise entire, the others slightly abbreviated behind ; 

 strife- punctiite to behind the middle, the third with the first dorsal puncture 

 slightly in front of the middle, the second about one-fourth from apex ; intervals 

 feebly convex. Beneath black, shining. Legs dark piceous or black. Length 

 .15-. 18 iuch ; 3.75-4.5 mm. 



Distinct from the others of the group by the characters above 

 given. 



It occurs in the Lake Superior region, the mountainous parts of 

 Wyoming, Colorado and Utah, and in California and Washington 

 In Dr. Horn's collection there is one specimen from Santa Monico, 

 S. Cal. 



24. B. qiiadriiluill Lee. — Form broad, slightly depressed; color black, 

 more or less seneous, shining. Head scarcely as wide as the thorax at apex ; paljn 

 black ; anteunse about one-half the length of the body, dark piceous or black. 

 Prothorax about one-half wider than long, as wide at base as apex ; apex emar- 

 ginate ; median line distinct, abbreviated at each end; transverse impressions 

 distinct; liasal impressions moderately deep, l)istriate ; sides with the margin 

 narrowly reflexed, slightly arcuate in front, obsoletely sinuate behind ; hind 

 angles subrectaiigular, finely carinate. Elytra rather less than one-half wider
