H. C. FALL. 71 



out order on the elytra, the prothorax is one-half wider than 

 long-, with the apex fully one-half as wide as the base, the 

 elytra are relatively a little longer, and there are some other 

 differences in detail. Oblongida differs notably in its dull 

 strongly alutaceous lustre, the beak is shorter, the antennal 

 club smaller, and there are many other differences obvious 

 when descriptions are compared. In tectiis the elytral setae 

 are subequal in length to the width of the interspaces. 



B. pruiiliuiis n. sp.— Oblong oval, black, moderately shining, 

 with a pruinose aspect because of the numerous white setae, which are 

 long, coarse, blunt at tip, and recumbent. Beak very short, stout, 

 evenly arcuate, scarcely half as long as the prothorax, rather finely 

 and not very closely punctate. Antennae nearly as in the preceding 

 species, except that the club is here distinctly compressed. Prothorax 

 densely punctate with a narrow median smooth line which is variable 

 in distinctness ; sides very broadly arcuate and feebly convergent from 

 base to near the apex, thence more strongly but not very abruptly 

 rounded, the apex about one-third as wide as the base. Elytra barely 

 perceptibly wider than the prothorax, slightly gradually narrowed be- 

 hind, intervals from two to three times as wide as the striae, the second 

 and third widest, interstitial punctures confused on all the intervals for 

 the greater part of their length. Prosternum feebly longitudinally con- 

 cave at middle, separating the coxae by two-thirds to three-fourths 

 their own diameters. Other characters nearly as in the preceding spe- 

 cies. Length, 3.6-4 mm. ; width, 1.8-1 95 mm. 



Type. — From El Paso, Texas. 



This and the preceding species are rather closely allied in 

 a general way, and especially by the long conspicuous setae ; 

 the present one, however, is larger and more oval in outline, 

 with shorter beak and more compressed antennal club. 



B, nevadicus n. sp. — Narrowly oblong oval, black, polished, legs 

 rufous; setae very fine, short and inconspicuous. Head finely sparsely 

 punctate, transverse impression distinct, broadly angulate in profile. 

 Beak stout, strongly arcuate, nearly four-fifths as long as the prothorax, 

 rather strongly and closely punctate. First funicular joint fully two- 

 thirds longer than wide, second nearly as long as wide, club rather 

 small, scarcely longer than the four preceding joints. Prothorax one- 

 fourth wider than long, sides very broadly arcuate and feebly convergent 

 to apical fifth, thence strongly rounded to apex, which is one-half as wide 

 as the base ; surface rather coarsely and densely punctate, with nar- 

 row distinct and nearly entire smooth median line. Scutellum small, 

 unimpressed. Elytra a little wider than and not quite twice as long 

 as the prothorax, about one-third longer than wide; striae fine, deep,
