I cannot trace any distinction betwixt the two supposed spe- 
cies I have ventured to unite. Our specimens vary in having 
the base of the elytra more or less bituberculate, and the upper 
surface, though most frequently piceous, has often a brassy tint.— 
This is quite consistent with Miiller’s character, “ fusco vel piceo- 
zeneus, coleopteris basi obsolete bituberculatis.”—J. H.
