rather deeply impressed, traceable almost to the middle, the surface 

 thence to the sides feebly convex, flat at base; elytra oblong-oval, not 

 three-fifths longer than wide, about a fourth wider than the prothorax, 

 the sides gradually a little more rounded basally, the humeri finely 

 denticulate; striae coarse, very deeply impressed, smooth, not in the 

 least punctulate; subscutellar puncture distinct, with a short oblique 

 scutellar stria; intervals equal throughout, rather strongly convex; 

 prosternal process margined. Length (9) 12.8 mm.; width 5.0 mm. 

 A single example unlabeled in the Levette collection and probably from 

 Indiana. 



Belongs to the adoxus group, but much shorter and stouter than 

 any member of that small eastern group known to me, and it may 

 be distinguished by the absence of the short sinuation of the thoracic 

 sides at base; in zephyrus Csy., which also belongs to this group, 

 the sides are sinuate at base for a notably great distance; rejeclus 

 Lee, seems also to be distinct from adoxus in its more elongate 

 form of body; the other varietal forms described by LeConte, 

 named suharcuatiis and sustentus, I have not seen, but by de- 

 scription at least, they do not seem to approach sufflatus in any 

 way closely. 



Euferonia Csy. ' 

 The species of this genus are rather numerous and have a very 

 distinctive appearance; they appear to be peculiar to eastern 

 North America; the following has been sent me recently by Mr. 

 Chas. Dury, of Cincinnati: 



Euferonia roanica n. sp. — Narrower and more elongate than coracina, 

 convex and deep polished black, the tarsi and palpi piceous; head slightly 

 elongate, fully three-fifths as wide as the prothorax, with rather promi- 

 nent eyes; anterior impressions deep and straight, parallel and broad; 

 last palpal joint slender, much shorter than the third, narrowly truncate 

 at tip; antennae but slightly compressed, a little longer than the head and 

 prothorax, the latter fully as long as wide, the sides subparallel, almost 

 evenly arcuate, strongly, equally reflexed, the basal angles very obtuse, 

 blunt at tip; base arcuate laterally, not quite as wide as the moderately 

 sinuate apex having rounded angles; transverse impressions obtuse and 

 feeble; foveae deeply concave and somewhat punctured, parallel, nearly 

 twice as long as wide, the surface separating them from marginal gutter 

 elevated and subcariniform; median stria deeply impressed and sub- 

 entire; elytra parallel, with feebly arcuate sides, more rounding basally, 

 nearly three-fourths longer than wide, between a third and fourth wider 

 than the prothorax, gradually rounding in almost apical third, the 

 sinus very distinct; striae coarse, very deeply impressed, smooth or not 

 definitely punctulate; intervals very convex, subequal throughout, the
