California (San Francisco to Los Angeles). 



One of the most abundant of the Californian species and repre- 

 sented before me by a large series. It varies greatly in color, and 

 closely resembles mannerheimi Gemm. ; the latter, however, com- 

 pletely lacks the long coarse erect setae which are so conspicuous in 

 hystricula. 



8 D. hispidlis Lee. — Proc. Am. Phil. Soc, XV, p. 167. 



Oblong, somewhat stout, convex, feebly shining, pale flavo- 

 testaceous throughout except the sterna of the hind body, which, 

 as in hirtus, are blackish; vestiture dense, consisting of robust 

 recumbent hairs, feebly subdenuded in uneven wavy blotches on 

 the elytra behind the middle, and with coarse erect bristles of 

 moderate length. Head very densely punctate and coarsely pubes- 

 cent, the beak in the female subglabrous toward apex, very feebly, 

 evenly arcuate, rather slender, not quite as long as the head and 

 prothorax, the antennae inserted at apical two-fifths; between the 

 bases of the antennae there is a dilated flat polished and impunctate 

 area. Prothorax small, more than one-half wider than long, parallel 

 and rounded on the sides, convergent and sinuate, but not strongly 

 constricted, near the apex, the latter three-fourths as wide as the 

 base ; punctures moderate in size, deep, dense, the impunctate line 

 narrow and distinct. Elytra at base fully one-third wider than the 

 prothorax, much more than three times as long, parallel, gradually, 

 evenly parabolic in more than apical third; strial, punctures moder- 

 ately large, very deep and close-set ; intervals about three times as 

 wide as the punctures. Abdomen densely, rugosely punctate. Legs 

 short. Length 3.6 mm.; width 1.4 mm. 



New Mexico. Cab. LeConte. A distinct species not closely 

 allied to any other.; it differs from hirtus in its smaller, narrower 

 prothorax, and the shorter and sparser pubescence of the elytra, 

 although the erect setae are similar to those of that species in length 

 and abundance ; also, as remarked by Dr. LeConte, in the absence 

 of the interantennal sulcus. 



9 ». hirtus Lee— Proc. Am. Phil. Soc, XV, p. 166. 



Oblong, robust, convex, somewhat shining, pale flavo-testaceous, 

 the beak piceous ; sterna and their parapleurae black ; vestiture 

 dense, consisting of long robust recumbent hairs, yellowish-white 

 in color, scarcely mottled but subdenuded in a large clouded spot
