Form broadly oval, color pale castaneous ; pale area at apex not 



well defined TidullS 



Elytra entirely pale pallidus 



Elytra reticulate throughout. 



Very small, strongly convex, the elytra acutely rounded behind ; 



punctures obsolete ; color pale throughout nitidUS 



Larger, more depressed. 



Pale reddish-flavate throughout ; punctures of the elytral series 



distinct, at least toward the suture aquatilis 



Dark piceous-brown, the apex abruptly paler ; punctures obsolete. 



floridanus 

 Elytra piceous or piceous-black throughout. 



Elytra finely reticulate throughout, larger species, moderate in size. 



Eighth joint of antennae elongate OlJSCUrUS 



Eighth joint slightly transverse, and much shorter than the seventh. 



obtiisus 

 Elytra highly polished, not reticulate ; very minute species. 



naniilus 

 Punctures of the second and third series from the discal stria composed of 

 punctures which are large, deep and distinct in the middle third, but 

 obsolete toward base and apex. 

 Lateral series composed of very minute, nearly obsolete punctures. 



pusillus 

 Lateral series composed of widely dilated, crescentiform punctures. 



modestus 



Spinules at the apex of the prosternal process short II 



Discal stria very short and feeble, not extending beyond the middle ; body 



evenly elliptical, piceous-black, strongly reticulate ....Sllliallltaceiis 



Discal stria normal, obsolete at basal third ; body attenuate behind from 



the base of the elytra. 



Elytra very minutely, transversely strigilate ; color pale testaceous 



throughout. 



Punctures very feeble ; metasternal process very wide, the mesosternum 



in front of it short, transverse and tumid COnTergens 



Punctures distinct and rather distant ; metasternal process narrow, 

 shorter, the mesosternum before it long, rather narrow and flat. 



attentiatus 

 Elytra more coarsely reticulate in transverse wavy lines ; color intense 

 black above ; punctures of the series rather close and very deeply im- 

 pressed throughout the width elongatulus 



S. apicalis Melsh. — Proc. Ac. Phil., II, p. 102. — Oval, strongly convex, 

 very feebly attenuate behind the middle, about two-thirds longer than wide, 

 highly polished, piceous-black ; apex rather abruptly pale testaceous, the 

 general blackish tint being prolonged along the suture nearer the apex ; 

 under surface rufo-testaceous ; legs, antennae and trophi paler and more 

 flavate. Head polished, excessively minutely, feebly and very sparsely punc-
