and middle tarsi, and the hind tarsi in great part, blackish. Pubes- 

 cence not very dense, cinereous and brown or brovvnish-ochreous, 

 obscurely mottled on the elytra, the pale hairs forming a short feebly 

 defined line at the middle of the third interspace, and two very obscure 

 irregular transverse bands before and behind the middle, the brownish 

 spots consisting of three on the disk of each elytron surrounding the 

 pale line of the third interspace, and three larger sublateral spots, all 

 obscurely defined. Antennae unusually long and slender, attaining 

 the middle of the elytra, feebly incrassate, all the joints longer than 

 wide, the terminal one very little longer than the tenth. Eyes mod- 

 erately prominent, separated by about their own width. Head densely 

 punctate, a small smooth spot at the middle of the vertex, front not 

 carinate. Prothorax moderately transverse, conical, sides broadly 

 arcuate, feebly sinuate basally, clothed rather thinly with brownish- 

 ochreous pubescence which is not appreciably mottled, the coarse 

 punctuation strong and close. Elytra distinctly longer than wide, 

 sides broadly arcuate, striae fine, feebly punctured, intervals finely sub- 

 rugosely punctate. Pygidium oblique basally, vertical in apical half, 

 pubescence cinereous, rather sparse, a little condensed along the mid- 

 dle, punctuation distinct but not deep. Hind thighs rather slender, 

 armed with a tooth and two denticles ; hind tibiae not at all carinate 

 on the outer face, the terminal spur scarcely one-third the length of 

 the first tarsal joint. Length, 3 mm. ; width, 1.6 mm. 



California (Deep Creek, San Bernardino Mountains — 6500 

 feet). 



The type above described is a male. With it I have placed 

 a specimen from Kings River Canon which looks very simi- 

 lar and is probably identical. This latter is a female, and 

 differs in being a little stouter, the smooth spot on the ver- 

 tex obsolete, the antennae a little shorter, the ninth and tenth 

 joints nearly or quite as wide as long, the spur of the hind 

 tibia slightly more than one-third the length of the first tarsal 

 joint. This species looks like a large pa upe renins, the ob- 

 scure markings being of the same type, but it may be at 

 once separated from the latter species by its bicolored legs 

 and the very elongate antennae and shorter hind tibial spur, 

 especially of the male. 



B. chiricalmse n. sp. 



Form not very robust, nearly as in aureolus and fraterculus, black, 

 antennae entirely rufotestaceous, front and middle legs except the tarsi 

 and the extreme base of the middle femora, rufotestaceous ; hind legs 

 black. Pubescence not very dense, uniformly cinereous throughout. 

 Antennte as long as or slightly longer than the head and prothorax,
