than the club, the latter as in subacutus, the oblique pseudo-suture of 

 the eleventh joint, beyond the middle, deep and distinct; prothorax 

 shorter than in either of the preceding, much more than twice as 

 wide as long, much less than half as long as the elytra, which are 

 unusually short, barely longer than wide, without distinct impressed 

 lines, the very shallow lunate punctures everywhere widely separated, 

 serial and broad but well separated laterally; metasternal process 

 circularly rounded at tip, the bead rather flat and even but broader 

 than in the preceding species. Length 1.35-1.63 mm.; width 0.8 

 i.o mm. New Mexico (Luna). Erroneously placed with simplex 

 formerly by the writer validiceps n. sp. 



14 Body rather broadly oval in outline, narrowly parabolic behind, the 

 legs and antennae obscure testaceous; head very minutely, sparsely 

 punctulate; antennae only moderate in length, the third joint not 

 quite as long as the next two combined, the club as long as the entire 

 funicle; prothorax rather short, evidently less than half as long as 

 the elytra and much more than twice as wide as long; scutellum a 

 third wider than long; elytra barely at all longer than wide, the 

 punctures extremely shallow and feebly marked, broad and somewhat 

 confused postero-laterad; metasternal process scarcely extending 

 beyond the coxae, broad, circularly rounded and finely, evenly 

 margined throughout at tip. Length 1.55-1.7 mm.; width 0.95-1.0 

 mm. Colorado (Boulder Co.). Two examples. . .mediocris n. sp. 



Body less broadly oval, strongly convex, very small in size : not very 

 narrowly parabolic behind, the legs and antennae piceous; head finely 

 sparsely punctulate; antennae moderate, the club long, rather less 

 dilated than usual; prothorax short, very much more than twice as 

 wide as long; elytra slightly elongate, much more than twice as long 

 as the prothorax, the punctures extremely feeble, not quite so broad 

 as in the preceding and more clearly separated postero-laterad; 

 metasternum broad, extending rather beyond the coxae, the apex 

 circularly rounded, moderately beaded. Length 1.33 mm.; width 

 0.78 mm. Northern Illinois (Highland Park) illini n. sp. 



15 Form broadly oval, very obtuse behind; legs and antennae piceous, 

 the latter with the third joint about as long as the next two, the 

 club as long as the funicle; head finely and sparsely but rather deeply 

 punctulate, well developed, half as wide as the prothorax, which is 

 rather large and but little more than twice as wide as long; scutellum 

 three-fifths wider than long; elytra barely at all longer than wide and 

 scarcely twice as long as the prothorax, the reticulate ground sculp- 

 ture traceable to the base but becoming subobsolete, the series 

 composed of small and very shallow, lunate punctures, less feeble 

 and larger laterally toward tip, the serial punctures extending to 

 base but becoming very minute; metasternal process extending 

 rather beyond the coxae, variable in width perhaps sexually, rounded 

 and beaded at tip. Length 1.28-1.65 mm.; width 0.75-1.05 mm. 

 California (San Diego). Five examples conjunctus Csy. 



Form more elongate-oval, broadly parabolic apically, larger in size, very 

 convex, the legs and antennae piceous-black; head minutely, sparsely 

 punctate, rather less than half as wide as the prothorax, the apex
