152 MEMOIRS ON THE COLEOPTERA 



than half as wide as the prothorax, confluently and rather coarsely 

 punctate anteriorly, discretely and rather sparsely toward base, 

 the eyes very moderate, separated by nearly three times their width; 

 clypeus one-half wider than long, feebly trapezoidal, the sides 

 parallel basally, feebly sinuate anteriorly, the apex arcuato-truncate, 

 broadly, gradually and strongly reflexed, the surface coarsely and 

 confluently punctate throughout, the suture entire, evident, broadly 

 sinuate; antennal club arcuate, much longer than the stem; last 

 palpal joint rather slender; prothorax two-thirds wider than long, 

 the sides parallel, feebly and evenly arcuate from base to apical 

 third, there becoming arcuate and converging; basal angles moder- 

 ately rounded, the apical short, not sharp; basal bead interrupted at 

 the middle, the lateral extremely fine; surface broadly convex, finely 

 but distinctly, sparsely punctate, barely at all more coarsely laterad; 

 scutellum rather small, not very acute, ogival; elytra nearly one-half 

 longer than wide, subcylindric, obtusely rounded at apex, fully a 

 fourth wider than the prothorax, the punctures fine and sparse, 

 partially in unimpressed series; pygidium transverse, convex, 

 finely scabrous, having sparse pubescence basally; hind tarsi 

 rather thick, not evidently longer than the tibiae; sterna closely 

 pubescent. Female slightly larger and stouter than the male, 

 otherwise nearly similar, except that the head is scarcely half as 

 wide as the prothorax, the eyes a little smaller and the antennal 

 club small, not quite half as long as in the male; pygidium less 

 transverse, smaller and less convex, smoother, sparsely and feebly 

 rugulose, sparsely pubescent basally. Length (cf 9 ) 13.0-14.3 mm.; 



width 5.9-6.4 mm. California abrupta n. sp. 



Elytra at base not abruptly wider than the prothorax 2 



2 Last joint of the maxillary palpi stout, the scar-like marking on it? 

 upper surface broadly oval, flat and opaquely scabriculate. Body 

 (cf) elongate-oval, very convex, smooth, pale brownish-flavate 

 throughout, the elytra still more flavate; head slightly more than 

 half as wide as the prothorax, convex, black, the punctures strong 

 but separated, larger, shallower and confluent anteriorly; clypeus 

 as in the preceding but only two-fifths wider than long, the apex 

 extremely reflexed; surface coarsely, transversely rugose, becoming 

 smooth in the deeply concave apical part, the median line canalicu- 

 late; suture fine, feebly defined, sinuate at the middle; eyes separated 

 by three times their width; antennal club strongly curved, very 

 much longer than the stem; prothorax two-thirds wider than long, 

 the sides rounded, feebly, then more strongly, converging anteriorly, 

 the basal angles very broadly, gradually rounded into the sides, 

 obliterated; basal bead distinct and entire, not at all interrupted; 

 punctures fine, sparse, becoming rather coarse and close-set laterad; 

 scutellum ogival, finely, sparsely punctate; elytra oval, not quite 

 one-half longer than wide, at the middle distinctly wider than the 

 prothorax, circularly rounded in apical two-fifths; punctures fine, 

 feebly impressed, more distinct and lineate laterad, lineate every- 

 where except near the suture, the series unimpressed; pygidium not 

 very transverse, strongly convex, scabriculate, the sparse hairs
