110 AMERICAN COLEOPTERA. 



transverse impressions nearly obsolete; basal impressions deep, bistriate; sides 

 with the margin very narrowly reflexed. strongly arcuate nearly to base, sinuate 

 in front of the hind angles, which are rectangular and carinate. Elytra scarcely 

 wider than the thorax, elongate, oblong-ovate, subparallel, finely striate ; striae 

 very distinctly punctate to behind the middle, the first, second and fifth entire, 

 the latter slightly grooved at tip, the others more or less abbreviated behind ; 

 intervals flat, the third with the first dorsal puncture about one-fourth from base, 

 the second about one-fourth from apex. Beneath black, shining. Legs black, 

 the tibiae and tarsi more or less piceous. Length .18-. 20 inch ; 4.5-5 mm. 



The above description was taken from LeConte's type and one 

 specimen in Dr. Horn's collection. Two others in the LeConte col- 

 lection agree with it in all respects. Two examples sent to me by 

 Mr. H. C. Fall, from California, differ in having a small, rather ill- 

 defined, submarginal pale sj^ot on the elytra about one-fourth from 

 apex, and the elytra are slightly more deeply striate. In other re- 

 spects they agree with the description. For the single specimen in 

 my cabinet I am indebted to Mr. Fall. 



It is known to me only from California. 



91. B. iiiorinon n. sp. — Larger and less convex than grandicolle ; color 

 nigro-feneous, shining, the elytra often with a transverse band of variable length 

 about one-third from base and another about one-third from apex rufous. Head 

 not alutaceous, scarcely as wide as the thorax at apex ; palpi piceous ; antennae 

 less than one-half as long as the body, piceous or dark fuscous, the basal joints 

 scarcely jjaler. Prothorax subquadrate, about one-half wider than long, slightly 

 narrower at base than apex, rugose at base ; apex truncate; median line distinct, 

 subentire; anterior transverse impression nearly efiiiced, the posterior distinct; 

 basal impressions broad, moderately deep, bistriate ; sides with the margin nar- 

 rowly reflexed, arcuate in front, slightly sinuate behind ; hind angles subrect- 

 angular, carinate. Elytra slightly wider than the thorax, elongate, oblong-ovate, 

 subparallel, moderately deeply striate; striae entire, distinctly punctate nearly to 

 apex, the fifth slightly grooved at tip; intervals slightly convex, the third with 

 the first dorsal puncture about one-third from base, the second about one-fourth 

 from apex. Beneath black, shining. Legs rufo-piceous, the femora usually pice- 

 ous. Length .20-.24 inch : 5-6 mm. 



Most nearly related to gTandkolle, but sufl3.ciently distinct by the 

 characters given above. At first sight it recalls B. scudderi. 



Described from four specimens from the vicinity of Salt Lake, 

 Utah, and one from Sherman, Wyo. I have since writing the above 

 seen one other si^ecimen from Utah and three from California. 



92. B. obtusaiigulum Lee. — Form moderately robust ; color black, usually 

 distinctly bronzed, rarely tinged with bluish, shining. Head scarcely as wide as 

 the thorax at apex ; palpi black ; antennae about cme-half the length of the body, 

 black. Prothorax subquadrate, about one-half wider than long, scarcely narrower 

 at base than apex; apex very feebly emarginate ; median line fine, usually ab- 

 breviated before and behind; transverse impressions moderately distinct ; basal
