only slightly more than twice as wide as long, the apex scarcely 

 more than two-thirds as wide as the base, deeply sinuate, the 

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

 coming straight toward apex, the punctures longitudinally coales- 

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

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

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

 ^*' ^ rounded and apex acutely ogival, the flanks vertical, with an 

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

 ^ tures fine, feeble, irregular, muricate, coarsely so laterally ; abdo- 

 men finely, sparsely punctate. Length 7.0 mm. ; width 3.8 mm. 

 California (San Diego) inflatus Lee. 



Body less broadly and more oblong-oval, the prothorax less narrow^ed 

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

 black or piceous-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 apex three-fourths as wide as the base, otherwise in form 

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

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

 little wider, rather acutely ogival at tip, the sides less arcuate than 

 in tnjlatus, similarly sculptured, the impression at the side margin 

 very much smaller, less elongate and feebler ; abdomen similarly 

 finely, sparsely punctured, the third segment of the female with a 

 I'ounded 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 2.62—3.42 mm. California (near San Diego and at Re- 

 dondo Beach) ovif ormis n. sp. 



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



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

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

 ovif ormis but with coarse and still sparser sculpture ; prothorax 

 as in oviformis but with the punctures fine, feeble and sparse, the 

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

 longitudinally plicatulose laterally ; elytra in outline nearly as in 

 oviforjuis 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 

 5.2—5.9 mm. ; width 2.S-3.15 mm. California (Los Angeles Co.).
