integris impunctatis, niarginali ad medium postice abbreviata ; epipleu- 

 ris modice excavatis, impunctatis, stria laterali profunde impressa ; tibiis 

 anticis fortiter 5-dentatis. Long. -22. 



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

 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 stria3 being very short. 



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

 tulatus, tborace stria laterali 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 If. 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. (Platysouia) aequiis. Elongatus, parallelus depressus, niger 

 nitidus, tborace dense subtiliter punctate-, elytris punctulatis Btriis pro 

 fundis, integris 2nda autice subobliterata ; tibiis anticis 4-deutatis, me- 

 sosterno stria niarginali antice obliterata. Long. - 12. 



Southern States, rare. This species is not wider than //. 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.

22?. S. seminitens. Ovalis convexus, aeneus, medio nitidus, capita 



linea transversa profunda, superiore arcuata obsoleta, tborace nun-,. 

 punctato, plaga basali transversa L-evi, elytris stria suturali integra cum 

 dorsali interna arcuatim conjuncta, dorsalibas extrorsum Rensim longi- 

 oribus, externa sinuata fere integra, niarginali interna utrinqae valde 

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

 ultra striam dorsalem externam baud extensia ; tibiis anticis fortiter 

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