314 MEMOIRS ON THE COLEOPTERA 



bordered below by a distinct obtuse ridge, between which and the 

 sides the pubescence is sparser; pygidium rather transverse, obtusely 

 triangular, the very dense decumbent hairs rather less coarse than 

 than those of the elytra, subsimilar to those of the abdomen but 

 denser; tibiae as in the preceding. Length 19.0-20.0 mm.; width 

 9.09.8 mm. Four examples. 



Female differing greatly from the female of blaisdelli, much stouter, 

 more oval, rather shining but with less minute and closer vestiture; 

 head with rather dense coarse prostrate, and some long erect, hairs, 

 the clypeus very short, rounded at the sides and angles, the punctures 

 stronger and more separated than those of the front, the prostrate 

 hairs rather sparse; medial tumidity of the vertex obsolete in the 

 male of this as well as blaisdelli not so strong as in the preceding; 

 antennal club short and broadly oval, the last palpal joint very small, 

 not half as long as the club, oval, obtusely pointed, glabrous and 

 with a shallow excavation extending only a little beyond the middle 

 of the length; prothorax nearly similar in outline but more developed 

 than in the male, the punctures not quite so large and dense through- 

 out, the long erect vestiture very abundant, the shorter semi-erect 

 hairs distinct but sparse; scutellum densely but finely pubescent; 

 elytra much larger and broader, the subdecumbent hairs fine and 

 numerous but much less dense than in the male; pygidium very much 

 larger and still more transverse, the short fine hairs rather dense as 

 on the abdomen ; general color of the body much paler red-brown than 

 in the male. Length 20.5-21.0 mm.; width 11.0-11.4 rnm. Two 

 examples. 



California (Los Angeles Co.) fossiger Csy. 



A Male similar to the male of fossiger in almost every way, except 

 that the vestiture is pale yellowish and even denser and that the 

 last palpal joint is shorter, with more broadly open excavation and 

 only about three-frouths as long as the antennal club; the hind tarsi 

 are much shorter, being very much shorter than the tibiae; in 

 fossiger they are only a little shorter than the tibiae and are thicker. 

 Length 18.5 mm.; width 9.4 mm. California (Los Angeles Co.). 



One example brevitarsis n. subsp. 



B Male similar to the male of fossiger in size and general form, but 

 with the pubescence, which is everywhere similarly dense, of a deep 

 ochreous-yellow color; last palpal joint shorter than fossiger, nearly 

 as in brevitarsis, but more hairy than in any of the other allied 

 forms; hind tarsi much shorter than the tibiae; pygidium smaller, 

 more convex and rather less transverse than in any of the others. 

 Length 19.5 mm.; width 9.8 mm. California (Los Angeles Co.). 



One specimen ochreata n. subsp. 



C Male nearly as in the male of fossiger but with a relatively larger 

 prothorax and with the last palpal joint obviously different, being 

 shorter and more broadly oval and not more than three-fourths 

 as long as the antennal club, the excavation broader and not 

 partially closed by the overhanging walls beyond the middle as 

 it is in fossiger; pygidium and tarsi nearly similar. Length
