242 MEMOIRS ON THE COLEOPTERA 



elytral punctures fine, unusually close-set. Body moderately 

 stout (cf), or notably so and very much larger (9), moderately 

 shining, pale testaceous in color, the anterior parts somewhat 

 darker; head moderate or relatively small, the eyes separated by 

 three-fourths their width in both sexes; antennae (c?) very stout and 

 imbricate basally, slender apically, extending to apical fourth of 

 the elytra, the last joint very long, as long as the preceding, nearly 

 five times as long as wide, much compressed, rounded at apex, sub- 

 claviform or gradually wider from base to the apical arcuation, the 

 apical bevel on the inner side very feeble and long, its summit 

 feebly protuberant, or ( 9 ) slender, perceptibly tapering and strongly 

 serrate distally, barely half as long as the body, the last joint parallel, 

 three times as long as wide, as long as the preceding, truncate at 

 apex, less compressed than in the male, the apical slope on the inner 

 face very gentle and beginning behind the middle; prothorax trans- 

 verse, rather strongly punctured, closely and rugosely so laterally, 

 the anterior teeth small, the intermediate large, very acute and 

 somewhat reflexed as a rule; scutellum very obtuse; elytra a third 

 wider than the prothorax, about two-thirds longer than wide in 

 both sexes, the feebly arcuate sides much more rapidly converging 

 from base to apex in the male than in the female, the raised lines 

 very feeble; metasternal pubescence greatly developed in both 

 sexes but especially in the male; tarsi only moderately slender, the 

 canaliculation fine but distinct and entire on the middle and pos- 

 terior. Length (d*) 38.0, (9) 53.0 mm.; width (cf) 14.0, (9) 21.4 

 mm. California and Oregon. [P. californicus Mots., Bull. Mosc.,

A Smaller than the preceding and much more parallel in the male, 

 the elytra only very feebly narrowing behind and more broadly 

 rounded at apex; color, sculpture and general features similar; 

 head relatively much smaller, the eyes less separated, distant by 

 one-half their width; antennae (cf) not quite so stout basally 

 but otherwise similar, the last joint very slender and compressed, 

 five times as long as wide, parallel, not inflated apically and not 

 at all modified on the inner face; tarsi notably more slender than 

 in californicus. Length (cf ) 31.5 mm.; width 12.4 mm. Cali- 

 fornia (locality not recorded) ineptus n. subsp. 



B Very much smaller than californicus but similar in its pale tes- 

 taceous color, only the head being darker however, shining, convex; 

 head similar, the eyes separated by two-thirds their width; an- 

 tennae ( 9 ) about half as long as the body, very slender, the outer 

 joints but slightly serrate, the last evenly oval, about as long as 

 the preceding but only twice as long as wide; prothorax as in 

 the two preceding though much more finely, sparsely and less 

 conspicuously punctate; scutellum broad, very obtuse; elytra 

 three-fifths longer than wide, finely, closely punctate; tarsi long, 

 as in californicus but rather more slender, the intermediate barely 

 at all less slender than the posterior and not decidedly so as is
