70 CASEY 



and not very closely punctate, the punctures sharply muricate and 

 minutely setigerous ; a few very irregular and more convex 

 longitudinal lines are evident; prosternum sparsely, shallowly 

 punctate; anterior tibiae strongly but very obliquely prolonged 

 externally at tip, the external edge but feebly sinuate and finely, 

 inconspicuously spinulo-serrate ; epipleurae subconcave basally, 

 sparsely punctate and hairy throughout. Length 8.0-11.0 mm. ; 

 width 4.8-6.6 mm. California (San Diego) difficilis Lee. 



Form nearly as in difficilis but less broadly oblong-oval, opaque, 

 glabrous, the punctures less evidently micro-setigerous, the sides 

 beneath much less ciliate, the hairs of the epipleurae and femora 

 much shorter and less conspicuous ; head nearly similar but with 

 the reflexed clypeal margin still more feeble and very shallow, 

 the lateral notches very small but more evident ; prothorax nearly 

 similar but with the sides rather less strongly converging from 

 base to apex, the punctures almost similar; elytra more evidently 

 elongate, as wide as the prothorax, parallel, nearly straight at the 

 sides, with more numerous and narrower longitudinal lines of 

 slight convexity, the surface less coarsely and more feebly rugose, 

 with much smaller, sparser and rather less strongly muricate 

 punctures ; prosternum densely and rather finely punctato-rugose ; 

 anterior tibiae nearly similar but more strongly sinuate externally 

 beyond the middle ; epipleurae flatter, with the outer margin less 

 deflexed basally, rather less coarsely, very sparsely punctate ; 

 flanks of the elytra above the epipleurae more prominently rounded 

 in profile than in other species except difficilis. Length 9.7 mm. ; 

 width 5.9 mm. California (Los Angeles Co.)...agnatus n. sp. 



13 Body oblong, convex, rather narrow (c?) to very stout (?), dull 

 in the former, more alutaceous and with the elytra rather shining 

 in the latter, glabrous, ciliate at the sides, the femora with short 

 and sparse yellow hairs ; head with moderately strong punctures, 

 gradually close toward the transverse suture, the apex of the 

 clypeus very feebly reflexed, not at all so near the median sinus, 

 the lateral notches obsolete ; prothorax nearly as in difficilis but 

 less transverse, strongly narrowed with evenly arcuate sides from 

 base to apex, the apex evenly, deeply, circularly emarginate, with 

 rather pronounced and only narrowly blunt angles, the basal 

 angles and explanate sides nearly as in difficilis^ the explanate 

 surface flat but diminishing in width at the basal angles, the fine 

 raised margin similar; surface convex, more minutely, sparsely 

 punctured, the punctures slightly larger and micro-setigerous 

 laterally though smaller and much sparser than in difficilis ; 

 scutellum rather evident ; elytra slightly elongate, equal in width 

 to the prothorax, with some feebly convex longitudinal lines, the 

 punctures, irregularly disposed for the most part between these 

 smooth lines, unusually coarse, numerous, moderately muricate 

 and micro-setigerous; prosternum sparsely punctate, especially 

 strongly so on the process, feebly and sparsely f ulvo-pubescent ;
