312 MEMOIRS ON THE COLEOPTERA 



broader basally; prothorax throughout as in the preceding but a little 

 smaller and rather more transverse, the punctures still stronger, 

 very close-set, the vestiture nearly similar, the scutellum similarly 

 clothed; elytra much shorter, barely a fourth longer than wide, fully 

 two-fifths wider than the prothorax, rather more rounded at the sides, 

 the oblique lateral impression distinct, the humeral umbo strong; 

 surface scarcely at all rugulose, unusually finely, densely punctate, 

 more closely and finely than in the preceding; pygidium more convex 

 and transverse, distinctly wider than long, the vestiture dense and 

 dual, wholly decumbent, consisting of short hairs, some of which are 

 narrowly squamiform, and others very slender, also with some longer 

 and more erect hairs; abdomen rather densely clothed throughout 

 with a somewhat similar combination of hairs; hind tarsi slightly 

 shorter than the tibiae; first tooth of the anterior tibiae broad and 

 obtuse in the type, which however shows the effects of long use. 

 Length (cf ) 20.5 mm.; width 9.6 mm. California (Los Angeles Co.). 



vestita n. sp. 



Elytral vestiture always very short, more or less dense, generally slightly 

 squamiform 8 



8 Body shorter and stouter in form, the elytra a fourth to third longer 

 than wide and much wider than the prothorax in both sexes 9 



Body more elongate and cylindric, the elytra fully two-fifths longer than 

 wide and less exceeding the prothorax in width in both sexes. . . . 10 



9 Vestiture notably coarse, pale tawny-yellow in color; integuments 

 red-brown, slightly shining, the humeral umbo blackish; head and 

 concave clypeus equally and very densely clothed with decumbent 

 and coarse, basally somewhat dilated hairs, interspersed with long 

 fine erect hairs, the clypeus with rounded angles, the apex sometimes 

 feebly sinuate medially; last pal-pal joint only three-fourths as long 

 as the antennal club, broadly oval, with a broad and very deep ex- 

 cavation, extending throughout the length; prothorax of the usual 

 form, obtusely angulate at the sides and slightly widest at the middle, 

 the margins barely at all crenulate, the basal angles obtuse, rather 

 variable, not distinctly to rather decidedly rounded; punctures 

 strong, deep and dense, the vestiture rather dense, the decumbent 

 hairs rather long, inflated basally, the long erect hairs moderately 

 numerous, the usual narrow median line and broad lateral conden- 

 sations visible; scutellum with very dense vestiture, still coarser 

 than that of the pronotum; elytra with rather arcuate sides and 

 gradually obtuse apex, two-fifths wider than the prothorax, the 

 decumbent vestiture moderately dense and consisting of very slender, 

 gradually pointed scales, the general surface coarsely but feebly, 

 irregularly rugulose and with moderate and well separated punctures ; 

 pygidium slightly transverse, triangular as usual, the dense vesti- 

 ture still coarser than that of the elytra, that of the abdomen nearly 

 similar but white; first anterior tibial tooth strong and pointed. 

 Length 18.0-23.0 mm.; width 9.0-11.0 mm. Ten examples. 



Female nearly similar to the male in general size and outline, though 

 a trifle more elongate, much more shining, brighter testaceous, the 

 humeral umbo not darker, the head with very fine decumbent hairs,.
