308 CASEY 



confluent near the orbital carinae, the sides before the eyes strongly 

 converging and strongly, evenly arcuate, becoming subparallel 

 near the eyes; prothorax large, subequal in width to the elytra, 

 fully four-fifths wider than long, distinctly narrowed toward the 

 broadly sinuate apex, the sides evenly and moderately arcuate ; 

 punctures small but deep and rather close-set, gradually moder- 

 ately coarse and forming long rugae toward the sides ; elytra two- 

 fifths longer than wide, obtusely ogival at tip, just visibly inflated 

 posteriorly, the series laterally composed of only moderately 

 coarse, elongate and approximate punctures, those of the intervals 

 almost similar; abdomen finely and sparsely but strongly punc- 

 tate. Length 7.0 mm.; width 3.15 mm. California (Catalina 

 Island) insulare n. sp. 



Scutellum small or moderate 36 



36 — Sides of the prothorax more or less abruptly, strongly con- 



verging and straight or feebly sinuate toward apex 37 



Sides of the prothorax ev'enly rounded 38 



37 — Body stout, oblong-oval, convex, shining, the elytra slightly 



alutaceous, black, the legs very dark rufo-piceous ; head not 

 very coarsely, irregularly and in great part rather sparsely punc- 

 tate, the sides before the e3'es strongl}' converging, broadly and 

 evenly arcuate ; prothorax four-fifths wider than long, the sides 

 subparallel or very feebly diverging and nearly straight from the 

 basal angles to slightly before the middle, there rather promi- 

 nently rounded, the apex much narrower than the base and very 

 deeply sinuate; punctures strong and close-set, becoming only 

 slightly coarser but dense and longitudinally confluent toward the 

 sides; scutellum transverse, broadly rounded, impunctate; elytra 

 one-half longer than wide, slightly wider than the prothorax, 

 very obtuse at apex, the sides very sliglitly arcuate, the series 

 somewhat uneven, composed of very coarse punctures which are 

 broadly confused basally toward the humeral callus ; abdomen 

 finely rugulose, finely, sparsely punctate. Length 7.2 mm. ; 

 width 3.22 mm. California (San Bernardino Co.). 



gravidum n. sp. 



Body stout, shorter, oblong-oval, moderately convex and shining, cas- 

 taneous, the legs rufous ; head rather coarsely, perforately, some- 

 what unevenly and moderately closely punctate, the sides before 

 the eyes distinctly converging, evenly and strongly arcuate; 

 prothorax widest behind tlie middle, where the sides are broadly, 

 strongly arcuate, thence converging and less arcuate to the base, 

 the apex much narrower than the base and deeply sinuate, the 

 punctures strong and close-set, becoming but little coarser but 

 longitudinally confluent toward the sides ; scutellum small, wider 

 than long, angulate; elytra two-fifths longer than wide, very ob- 

 tusely parabolic at tip, only very slightly wider than the pro- 

 thorax, the sides evidently arcuate, the series in great part very 

 uneven, composed of close-set, moderately coarse punctures,
