Also recorded in the literature from Canada, and various localities not men- 

 tioned in the above list, but many of these records refer to the allied 

 species. 



Variations. — This species is quite variable in coloration. In the 

 males the front of the head varies from a deep blue to a greenish 

 blue, the middle of the pronotum bronzy green to bronzy brown, 

 with the sides greenish, bronzy, or bluish, and sometimes the elytra 

 has a violaceous tinge. The median depressions on the pronotum are 

 more or less variable, sometimes they are rather deeply depressed, 

 and again the depressions are scarcely indicated. The prehumeral 

 carinae are also variable in length, but always distinctly elevated. 

 The hind tarsi vary somewhat in length, and the anterior margin of 

 the prosternal lobe is subtruncate or more or less emarginate in front. 

 Length 4 to 5.75 millimeters. 



Host. — This species has been reared a number of times by dif- 

 ferent workers from hickory {Hicoria species) , which seems to be its 

 common host plant. 



This species is badly confused in nearly all collections, and the 

 citations to it in the literature usually refer also to a number of the 

 allied species, and great care should be used in citing any of the 

 older records of this species. 



Say says in the original description that the front of head is but 

 slightly punctured except on the vertex. In fact, the lower half is 

 rather densely, finely punctured, but the surface is concealed by the 

 long, white pubescence, and if this were denuded, the surface would 

 be almost impunctate under a low power lense. Specimens were 

 examined from near the type locality, and were identical with the 

 one used as a neotype, but it seemed advisable to use the examples 

 from West Virginia, since both sexes were reared, and the female 

 is known to be of that species. 



The males of this species can be separated from those of the 

 allied species by the following combination of characters: All of
