 angles right and not at all rounded, the sides broadly arcuate, be- 

 coming straight toward apex, the punctures longitudinally coales- 

 cent throughout, small mctlially, very coarse laterally ; elytra about 

 a fifth longer than wide, barely three times as long as the pro- 

 thorax but fully a fourth wider, the sides arcuate, the humeri 

 rounded and apex acutely ogival, the flanks vertical, with an 

 elongate impression at the side margin near basal third, the punc-

 California (San Diego) inflatus Lee. 



Body less broadly and more oblong-oval, the prothorax less narrowed 

 at apex and very much shorter and more transverse. Convex, 

 black or piccous-black, the head and prothorax generally slightly, 

 the under surface and legs more distinctly, rufescent, alutaceous; 

 head coarsely, densely punctato-scabrous, the sides strongly con- 

 verging and straight or virtually so, the epistoma only very feebly 

 prominent; prothorax two and one-half times as wide as long, the 

 sinuate ajjex three-fourths as wide as the base, otherwise in form 

 and sculpture as in injiatiis ; elytra a fifth longer than wide, evi- 

 dently more than three times as long as the prothorax and but 

 little wider, rather acutely ogiv^al at tip, the sides less arcuate than 

 in hiJJatus^ similarly sculptured, the impression at the side margin 

 very much smaller, less elongate and feebler ; abdomen similarly 

 finely, sj^arsely punctured, the third segment of the female with a 

 rounded impression at apex at each side, almost midway between 

 the middle and the margin, the fifth very faintly biimpressed or 

 slightly tumid along the median line. Length 4.7-6.5 mm. ; 

 width 3.63-3.42 mm. California (near San Diego and at Re- 

 dondo Beach) oviformis n. sp. 



4 — Oval but rather more oblong than in oviforynis^ convex, alutace- 



ous but with the elytra more polished than usual, black, rufo- 

 piceous anteriorly and beneath, the legs brighter rufous ; head as in 

 oviformis but with coarse and still sparser sculpture ; prothorax 

 as in ovifor?>iis but with the punctures fine, feeble and sparse, the 

 surface more opaque, the sculpture coarse but not so dense and 

 longitudinallv plicatulose laterally; elytra in outline nearly as in 

 oviforniis but relatively less exceeding the prothorax in width, 

 comparing the male types, in fact only slightly wider than that 

 part, more strongly, though not more closely, and more muri- 

 cately punctate, the sculpture becoming particularly rough toward 

 the sides ; abdomen minutely, sparsely punctate medially. Length
