finely reflexed at the sides, the punctures remote, fine, though 

 much larger and more distinct than in levettei and slightly more 

 so than \\\ pices cens ; prosternum finely, rather sparsely punctate, 

 the abdomen minutely and obsolescentlv so. Length 12. 5-13. 5 

 mm. ; width 5. 8-6. 35 mm. Probably San Diego Co. 



elliptica Csy. 



A — Form and sculpture nearly as in the preceding but narrower, 

 smaller in size and rather less convex, the elytra generally with 

 some excessively obsolete and broadly tumescent lines, deep 

 black, the elytra slightly more shining than in elliptica. Length 

 12. 0-12. 3 mm.; width 5.4-5.7 mm. Island of Sta. Catalina, 

 — Warren Knaus catalinae n . subsp. 



14 — Body narrower and more convex than usual, glabrous, deep 



black, strongly shining throughout ; head broadly sinuate at apex, 

 not impressed, finely punctured posteriorly, rather coarsely, 

 densely and subrugosely so anteriorly, the anterior canthus broadly 

 rounded, much more prominent than the posterior; prothorax 

 nearly three-fifths wider than long, the sides straight and parallel, 

 broadly rounding slightly before the middle, converging and 

 less arcuate apically, the apex broady and circularly emarginate, 

 almost three-fourths as wide as the base, with the angles right 

 and slightly blunt; surface very minutely, sparsely punctate, but 

 little less minutely or remotely so laterally, the edge strongly 

 beaded ; scutellum but little wider than long, moderate, tri- 

 angular ; elytra rather more than one-half longer than wide, 

 convex, smooth, with three very feeble eroded lines apically, 

 where also there are some coarse creases, very minutely, remotely 

 punctate, the lateral margin finely reflexed ; prosternum not closely 

 punctate, strongly and rather finely so anteriorly, very minuetly 

 on the process; abdomen smooth. Length 13.5 mm.; width 

 6.2 mm. Kern Co laevigata n. sp. 



15 — Form oblong, more parallel, moderately convex, deep black, only 



slightly alutaceous throughout above, still more shining beneath; 

 head rather finely but strongly, moderately closely and subevenly 

 punctate throughout, deeply and broadly sinuate at apex, the lobes 

 feebly impressed, the anterior canthus very broadly rounded, 

 slightly more prominent than the posterior; prothorax three-fifths 

 wider than long, the sides feebly converging from the base nearl}'' 

 to the apex and slightly arcuate, then gradually more arcuate and 

 convergent to the apex, which is broadly sinuate and two-thirds 

 as wide as the base, the angles right, narrowly rounded ; surface 

 minutely, sparsely punctate, gradually rather strongly, deeply 

 and much less sparsely so and micro-pubiferous laterally ; scutellum 

 large and broadly triangular, obtuse at tip ; elytra as wide as the 

 prothorax, fully one-half longer than wide, the sides straight, with 

 the margin more widely reflexed basally, the apex angulate ; sur- 

 face rather gradually declivous behind, nearly smooth though each 

 with about six very obsolete lines of greater convexity, the apex
