thin, inconspicuous; posterior angles carinated, very slightly excurved, acute. 

 Scutel convex, acute and slightly elevated behind. Elytra whitish, with 

 striae of dilated punctures; the exterior edge black, and an elongated black 

 spot upon the suture, widest behind, and suddenly attenuated before the mid- 

 dle, extending in a mere hue [page 71] nearly to the scutel. Feet piceous; 

 tarsal joints progressively shorter and smaller to the last, not lobed beneath; 

 claws simple. 



"This apparently new species nearly resembles the lugubris of M. Pal. de 

 Beauvois in form; but it is a much smaller insect; the thorax is more polished, 

 with the punctures less apparent, the hinder margin not so deeply emarginated 

 for the base of the elytra, and the posterior angles rather more excurved. The 

 elytra, taken together, are widest just before the middle, and are not so much 

 contracted until towards the tip. The antenna) and tarsi are widely different 

 in these two species." (This is 4231 [Henshaw], E. militaris Harris.)

 From New Hampshire. Inhabits New Hampshire, Pennsylvania, and Ill-

 says that 'it is the verticinus, Beauvois,' also, and that he 'does not know which 

 [name] has the priority.'^ It is not to be found described in the 12 livraisons of 

 M. Pal. de Beauvois's ' Insectes,' the last of which was published in 1818; and as 

 Herbst published the 10th volume of his work in 1806, the name rubricollis, 

 given by him, has undoubtedly the priority, over that of rerticinus." (This is 

 4229 [Henshaw], E. rubricollis Herbst.)

 in Mr. Say's Manuscripts, under the name of Eucnemis humeralis. Besides 

 these two species, Mr. Say refers to the [page 74] same genus his Elaters mus- 

 cidus, unicolor, and clypealus, his Melnsis ruficornis, and eight new species, 

 inhabiting the I'nited States." (This is a misidentification=4050 [Henshaw],
