108 DESCRIPTIONS OF NEW SPECIES. 



behind the middle to the base, with the hind angles obtuse but 

 not rounded, and by the regular series of punctures on the elytra. 



372. E. texaniis. Alatus, elongato-ovalis, minus convexus, piceus 

 subnitidus, capite thoraceque confertim fortiter punctatis, hoc latitudine 

 fere duplo breviore, a basi antrorsum angustato, lateribus niodice rotun- 

 datis, angulis anticis acutis, posticis rectis, basi bisinuata ; elytris striis 

 punctatis vix impressis, iuterstitiis parce subtilius punctatis ; antennis 

 palpis pedibusque obscure ferrugineis. Long. "30. 



Two specimens, from Texas. This species is quite different by 

 the less convex body, and by the more distinct elytral stria?. The 

 wings are well developed both in it and in E. longulus, and the 

 metasternum is therefore longer than in the other species. Other- 

 wise I detect no structural difference. 



EPITRAGUS Late. 



373. E. aCUtllS. Obscure seneus, subnitidus, tenuiter cinereo-pubes- 

 cens, capite confertim punctato, thorace latitudine longiore, antrorsum 

 angustato, angulis anticis prolongatis, acutissimis, parallelis ; elytris 

 punctulatis, vix obsolete striatis. Long. >46 — '50. 



Texas, Kansas, and Mexico. This species is distinguished 

 from the next by the proportions of the thorax. The thorax of 

 the female is densely and finely punctured, the sides are very 

 slightly rounded, and not thickened, and the anterior angles are 

 prolonged and parallel. 



In the male the thorax is less densely punctured, the sides are 

 absolutely straight, the margin is thickened, the anterior angles 

 prolonged and parallel, the disc flattened and excavated, with two 

 elevations extending to the apex which is moderately emarginate 

 between them : the middle of the excavation is feebly carinated. 



374. E. a rti iid in is. Obscure ieneus, subnitidus, tenuiter cinereo- 

 pubescens, capite confertim punctato, thorace latitudine haud longiore, 

 antrorsum angustato, angulis anticis prolongatis, acutissimis ; elytris 

 punctulatis, obsolete striatis. Long. '40. 



Middle States ; on salt marsh, and on coarse grass near the 

 ocean. The thorax of the female is slightly rounded on the sides, 

 less densely punctured than in the preceding species, not longer 

 than its width, and feebly channelled in the middle. 



In the male the thorax is sculptured as in the preceding, but 

 the excavation is deeper and scarcely carinated ; the elevations
