DESCRIPTIONS OF NEW SPECIES. 



integris impunctatis, marginal! ad medium postice abbreviata ; epipleu- 

 ris modice excavatis, impunctatis, stria lateral! profunde impressa ; tibiis 

 anticis fortiter 5-dentatis. Long. '22. 



Illinois ; Mr. M. Schuster. Resembles in form and sculpture 

 H. civilis, but belongs to a different division of the genus. It is 

 allied to H. marginicollis, but is readily known by the marginal 

 stria of the elytra being obliterated behind the middle, and the 

 internal three dorsal stria? being very short. 



225. H. perplexus. Ovali-oblongus, niger nitidus, subtiliter punc- 

 tulatus, thorace stria lateral! a margine remota, externaque brevi ad 

 angulo antico valde approximata, elytris striis dorsalibus sex integris 

 leviter punctatis, internis duabus antice arcuatim conjunctis, marginal! 

 obliterata ; epipleuris profunde bistriatis et leviter punctatis, tibiis an- 

 ticis 3-dentatis. Long. -20. 



Middle and Western States, rare. Allied to H. americanus, 

 and, like it, having the mesosternum truncate ; it differs, however, 

 by its larger size and more oblong form, as well as by being dis- 

 tinctly punctulate, both above and beneath. 



226. H. (Platysoma) aequus. Elongatus, parallelus depressus, niger 

 nitidus, thorace dense subtiliter punctate, elytris punctulatis striis pro- 

 fundis, integris 2nda antice subobliterata ; tibiis anticis 4-dentatis, me- 

 sosterno stria marginal! antice obliterata. Long. '12. 



Southern States, rare. This species is not wider than H. pa- 

 rallelus, but is as depressed as H. lecontei. The mesosternum 

 is deeply emarginate, and the stria, though bending around at 

 the sides, is not distinct at the middle. Besides the apical tooth, 

 the middle tibia? have two small teeth at the middle, and the hind 

 tibiae a single one, as in H. parallelus. 



SAPRINUS LEACH. 



227. S. seminitens. Ovalis convexus, aeneus, medio nitidus, capite 

 linea transversa profunda, superiore arcuata obsoleta, thorace rugose 

 punctate, plaga basali transversa Isevi, elytris stria suturali integra cum 

 dorsali iuterna arcuatim conjuncta, dorsalibns extrorsum sensim longi- 

 oribus, externa sinuata fere integra, marginali iuterna utrinque valde 

 abbreviata, externa integra, a medio postice confertim punctatis, punctis 

 ultra striam dorsalem externam haud extensis ; tibiis anticis fortiter 

 dentatis, tibiis tarsisque obscure rufis. Long. -13. 



Nebraska; Mr. "Dike. Related to S. sphseroides, but the
