and rough punctures closely set together. The anterior lobe 

 is a little deflexed, and the lateral strige are almost parallel, 

 and therefore end anteriorly widely apart. The mesosternura 

 in front is transversely bistriate, and the lateral fovege, which 

 constitute the character of a true Hetoirius^ are very shallow. 



Hetcerius trtstriatus, Horn. 



Several of the American Hefcerii are very differently con- 

 structed from those of the Old World. This species is one of 

 them. The presternum is parallel and prominently built out 

 in the central region, and the median part also of the lobe is 

 abruptly built up in the same way ; but the sides of the lobe 

 maintain their normal level, and thus the lobe is tripartite ; 

 the strife are very distinct, parallel, and close together in 

 front, widening out only at the coxae. The mesosternum 

 is marginate in front and bow-shaped ; the lateral pits are 

 shallow. 



Sternoccelis acutangulus^ Lewis. 



Breviter ovatus, brunneo-ferrugineus, sat nitidus : thorace dense 

 ocellato-punctato, angulis posticis transversim productis ; tibiia 

 anticis aspere ocellato-punctatis. 



L. 2-8, c. 3^ mill. 



Head and thorax densely punctate, punctures ocellated, 

 especially behind the neck. Forehead with two lateral strige, 

 which are feebly biangulate and do not meet in front, but 

 continue down part of the clypeus parallel to each other. The 

 thorax is punctate throughout its entire surface, which gives 

 an appearance of opacity ; the anterior angles are obtusely 

 produced and slightly reflexed, the sides are narrowly mar- 

 ginate and somewhat parallel for about three fourths of the 

 length, with the posterior angles produced and acuminate. 

 There is a small, rather transverse fovea at the base of the 

 angle, and the scutellum is smooth and triangular. The 

 elytra have three striae — first complete, second evanescent pos- 

 teriorly, third basal and short ; the dorsal surface is punctu- 

 late throughout, with the apices of the elytra clothed with erect 

 hairs. Prosternum broadly canaliculate, the canaliculation 

 being shining, with a few irregular punctures, deep and some- 

 what narrowed in front, shallow and broad behind, and a little 

 sinuate before the coxae j the base is broadly emarginate, with 

 the angles on either side produced somewhat acutely behind 

 the coxae. The sides of the thorax beneath are densely and
