AMKKICAN COLEOPTEKA. 421 



scutel minute. Elytra oval, less than one-tliird wider at the base than the pro- 

 thorax, hiuneri rounded, sides broadly rounded to the apex, declivity somewhat 

 |irecii)itous, the summit with acute granules, striae fine, each with a row of pale 

 l)iliform scales, jinnctures very small, intersjjaces wide, flattened, rugose; py- 

 tridium punctni'ed. squamous; underside closely i)unctured, densely scaly, scales 

 larfie. grayish white, crowded. Legs slender, femora subclavate, all armed with 

 a large, acute tooth, tibise subjiarallel, a little widened at the apex, articulating 

 surface ojjcn posteriorly, tarsi slender, third joint broadly bilobed, fourth a little 

 shorter than the two preceding joints combined, claws armed with a long slender 

 tooth, jtarallel to the claw and about two-thirds its length. Length 2.75 3. .5 mm. ; 

 0.11 0.14 inch. 



%. Last ventral segment with a broad, oval fovea, limited each side by a 

 prominent ridge, middle and posterior tibiae ungui(rnlate. 



Hab. — California, Utah (Salt Lake City, Walhsah Mountains). 



Two male and two female si)eciniens are before me. Very closely 

 related to the next species. Two specimens from Utah are a trifle 

 .smaller and have the pubescence a little more coarse. A specimen 

 in ]\Ir. Bolter's coll., which I consider to belong to the present species, 

 has the pubescence entirely grayish white, clo.sely resembling tyi)ical 

 specimens of the next. 



C afHlieiltus n. sp. — Oval, black, alH)ve uniformly clothed with grayish 

 white, piliform scales not closely appressed to tlie surface, underside densely 

 scaly, scales whitish, round or oval. Beak longer than the jirothorax, cylindrical, 

 of equal thickness throughout, punctured and striate from the base to the inser- 

 tion of the antennse. more finely ))unctulate beyond, antennae slender, inserted a 

 little beyond ( % ), or before ( 9 ) the middle ; first and second joints of funicle 

 elongate, latter slender, joints 3 4 longer than the outer joints, which are a little 

 wider outwardly ; club elliptical, acuminate. Eyes, head and general configura- 

 tion of prothorax as in Hiibpabesceus ; prothorax a little less rounded on the sides, 

 impressed each side before the middle, lateral tubercles small, transverse, dorsal 

 channel entire, more superficial about the middle and terminating in front in a 

 more or less profound fovea; scutel distinct, scaly. Elytra about one-fourth 

 wider at the base than the prothorax, finely striate, punctures very small, con- 

 (•ealed by scales, interspaces wide, flattened, rugose, declivity with small, acute 

 granules; pygidium more coarsely punctured. Legs and tarsi as in suhpubeaceux ; 

 anterior femoral tooth small. Length 3.0-3.25 mm.; 0.12-0.13 inch. 



%. Last ventral segment as in the preceding, middle and ])osterior tibia' un- 

 guiculate. 



This species, erroneously known in our lists and collections as 

 rajMP Gyll., bears only a superticial resemblance to its European 

 congener, while (littering in most important structural characters. 

 C r«j9ce Gyll. differs from afflaentus in the following points: Beak 

 very slender, almost piliform, more finely punctulate and glabrous 

 throughout, except at the base in the female; antennie inserted just 

 before the middle ( % ), or scarcely more than one-third from the
