404 Coleopterological Notices, IV. 



rather small, not very deep and slightly oval, the interspaces finely piinctu- 

 late ; scales whitish, narrowly oval, dense ; legs bright rufous, the tarsi 

 darker. Head minutely punctate ; constriction strong ; beak rather thick, 

 feebly arcuate, densely punctate in basal half, the apical regions sparsely so 

 and shining, equal in length to the head and prothorax ; antennje inserted 

 slightly beyond the middle, the basal joint of the funicle not quite as long as 

 the next three, second one-half longer than the third. Prothorax large, not 

 quite as long as wide, the sides rounded before the middle, thence feebly con- 

 vergent and nearly straight to the base, very deeply constricted at some dis- 

 tance behind the apex, the latter tubulate and barely three-fourths as wide as 

 the base ; disk widest before the middle. Elytra at base two-fifths wider than 

 the prothorax, two and one-half times as long, not quite one-half longer than 

 wide, the sides straight and parallel in basal half, then narrowly parabolic ; 

 strise fine, deep, scarcely at all impressed and with elongate narrow punctures 

 laterally. Length 2.0 mm. ; width 0.9 mm. 



California (Napa Co.). 



The single specimen, which I took at Suscol Station, is almost 

 entirely denuded above, with only a small spot of white scales near 

 the middle of each elytron and others yellowish in color scattered 

 thence to the apex ; the two spots are unsymmetrical and therefore 

 simply remnants of the vestiture ; the specimen is probably a female. 

 The beak is sparsely and rather finely setulose, with a small abrupt 

 tuft of white squamules above each eye. This species is easily 

 separable from obtectus by its shorter, more obese form and red 

 legs, from cinereus by its large prothorax, and from both by the 

 ditterent sculpture of the pronotum.

Oblong-oval, convex, black throughout, the legs rarely with a 

 feeble piceous tinge ; integuments densely clothed with elongate- 

 oval dark brown and cinereous scales, confusedly and not conspicu- 

 ously mottled on the elytra, the surface polished black when de- 

 nuded, the pronotum rather finely but very deeply and closely punc- 

 tate, the punctures not in actual contact, perforate. Beak differing 

 scarcely at all in the sexes, short, thick, strongly, densely punctate, 

 sparsely squamulose, with two erect tufts at base, very feebly arcuate 

 and but very slightly longer than the head and prothorax ; antennae 

 inserted near apical third in the male and two-fifths in the female, 

 the basal joint of the funicle fully as long as the next three, second 

 barely longer than the third. Prothorax but slightl}" wider than 

 long, the sides broadly arcuate, broadly, feebly constricted behind
