ROLAND HAYWARD. Ill 



Impressions deep, bistriate, the outer stria small ; sides with the margin very nar- 

 rowly reflexed, arcuate to base : hind angles obtuse, but not rounded, with a short, 

 fine carina. Elytra scarcely wider than the thorax, ohiong-ovate, finely striate, 

 more finely towards the sides and apex ; strije, entire, finely punctate to behind 

 the middle, the fifth slightly grooved at tip ; intervals flat, the third with the first 

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

 Body beneath and legs black, slightly peneous, shining. Length .17-.20 inch ; 

 4.25-5 mm. 



Most nearly related to grandicolle and mormon, but abundantly 

 distinct from either by the thorax scarcely narrower at base than 

 apex, with the sides not sinuate behind and the hind angles obtuse, 

 with the angular carina very short. From the former it also differs 

 by the entire elytral striae. 



It occurs from the Rocky Mountain region westward to the Pacific 

 coast, but seems to be local. Specimens are known to me from 

 Wyoming, Colorado, Utah, California and Washington. 



93. B. epiiippiger Lee. — Form slender, elongate, slightly convex. Head 

 and thorax black, scarcely feneous, shining ; elytra rufo-testaceous, with usually 

 the scutellar region, a transverse band slightly behind the middle and a shorter 

 one between this and the apex dusky or nearly black, the dark color rarely ex- 

 tending over the entire apical half and along the suture to base. Head rather 

 small, slightly narrower than the tliorax at apex; palpi rufous or rufo-piceous ; 

 antennae less than 'one-half the length of the body, fuscous, the basal joints 

 slightly paler. Prothorax nearly one-half wider than long, subquadrate, as wide 

 at base as apex, slightly rugose at base ; apex feebly emarginate ; median line 

 fine, abbreviated in front ; transverse iippressions moderate ; basal impressions 

 broad, deep, bistriate ; sides with the margin very narrowly reflexed, slightly 

 arcuate in front, rather feebly sinuate behind ; hind angles rectangular, finely 

 carinate. Elytra very slightly wider than the thorax, oblong-ovate, subparallel, 

 finely striate: strise entire, the outer nearly effaced at tip, finely punctate to 

 behind the middle, the fifth slightly grooved at apex ; intervals flat, the third 

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

 third from apex. Beneath nearly black, shining. Legs rufous, the femora some- 

 times darker. Length .13-. 18 inch ; 3.25-4.5 mm. 



A very pretty species, easily recognizable from its allies. The 

 range of variation has been indicated in the above description. 



It occurs from the Rocky Mountain region westward to the Pacific 

 coast, being known to me from Montana, Wyoming, Utah, Arizona 

 and California. 



94. B. rubigiiiosuin Lee. — Form broad, slightly convex; color piceous or 

 dark brown, with scarcely any aeneous lustre, shining. Head nearly as wide as 

 the thorax at apex ; palpi piceous; antennae scarcely one-half as long as the body, 

 piceous, the basal joints slightly paler. Protliorax subquadrate, about one-half 

 wider than long, scarcely narrower at base than apex; apex truncate; median 

 line fine, abbreviated behind ; transverse impressions distinct; basal impressions
