Coleopterological Notices. 5*7 



B. TilloSllS n. sp. — Moderately robust, piceous-black, paler beneath ; 

 elytra pale brownish, the suture and base slightly and indefinitely darker ; 

 legs and antennae pale liavo-testaceous, the latter infuscate ; head and pronotum 

 strongly shining, finely and very -feebly reticulate; abdomen polished, very 

 minutely, feebly reticulate, the basal impressions very much more coarsely and 

 strongly so. Head distinctly narrower than the prothorax, not distinctly con- 

 vex, with a few scattered, well-defined punctures, not tuberculate ; basal trans- 

 verse groove broadly impressed, strong ; median fovea rather badly defined ; 

 antennal tuberculations small but distinct ; suture fine and feeble, almost 

 completely obliterated in the middle ; antennre rather long, gradually and 

 moderately incrassate ; outer joints slightly transverse ; second much shorter 

 than the next two together, fourth and fifth longer than wide. Prothorax dis- 

 tinctly narrower than the base of the elytra, one-fourth wider than long ; sides 

 in anterior three-fifths just visibly divergent from the apex, and very feebly 

 arcuate, then convergent and feebly arcuate, broadly and very feebly sinuate 

 before the basal angles, which are very obtuse, rounded and not at all promi- 

 nent although definable ; lateral angles broadly rounded, not very distinct, 

 apical obtuse, distinctly rounded ; apex nearly two-fifths wider than the base, 

 both broadly, feebly arcuate ; disk very feebly convex, rather finely, densely 

 punctate, the punctures deep and well defined, sparser near the apex and 

 median groove, the latter very deep, widely impressed and conspicuous through- 

 out ; pubescence very long. Elytra subquadrate, distinctly wider at apex than 

 at base, one-third wider and one-half longer than the prothorax ; sides feebly 

 arcuate toward apex ; surface feebly impressed along the suture in basal half, 

 coarsely, very deeply and densely punctate ; punctures separated by from less 

 than to slightly more than their own diameters, very deep and perforate and 

 distinctly larger than those of the pronotum ; pubescence very long, rather 

 dense, cinereo-flavate and conspicuous. Abdomen slightly narrower than the 

 elytra, rather coarsely and densely punctate upon the convex portions, the 

 basal impressions impunctate, beneath densely punctate, the pubescence very 

 long. Length 5.0 mm. 



California. 



A very well-marked species in its extremely long conspicuous 

 pubescence, almost twice as long as in any other known to me. The 

 hypomera are about one-half as wide as the distance thence to the 

 coxiB, nearly flat anteriorly, strongly impressed along the middle, 

 the sutures almost completely effaced, the coxal fissures very long 

 and widel}^ open. The mentuni is very deeply impressed in the 

 middle toward base, almost excavated, highly polished ancl quite 

 devoid of reticulation, except near the lateral edges and sometimes 

 near the apex. 



For the present villosus may be associated with laticollis. 



B. Iieliulosus n. sp. — Rather robust, nearly parallel, black ; elytra i)ale 

 rufo-ferruginous, indefinitely clouded with piceous-black toward the suture,
