[A species of CartJinphonut which was afterwards cited by 

 Erichson as Elater anolatua Say, to which it bears no resem- 

 blance. It is the only species from the Atlantic slope of the 

 United States known to me. having the ungues tootheil : Say has 

 given an incorrect measurement ; it should read, length three- 

 twentieths of an inch. — Lkc] 



32. E. SANOUiNiPENNis nob. Jour. Acad. Xat. Sci. — Closely 

 resembles j>rcT;/.s/«s Fabr., which however, has the colors much 

 more vivid ; the punctures rather larger and more dense, particu- 

 larly those of the interstitial lines of the elytra ; the thoracic 

 spines longer ; and the second and third joints of the antennae of 

 our species are more cylindrical. [174]

 longer, and the thoracic punctures more obvious. 



Inhabits also Massachusetts. Harris.

 spot, it may be compared to the fn'i/ it t fat us Yahr., but is not much 

 longer than the head and thorax of that species.
