This species varies greatly in size and in the thickness of the antenri?e, 

 and somewliat in colors and distinctness of markings. 



The less mature specimens are pale dull ochreous, faintly shaded with 

 black, aud with the black of the connexivuiu obsolete. The old speci- 

 mens are almost black ; the fine deep punctures of the surface are quite 

 black ; the autennte are wholly black, and vary in the amount of erect 

 pubescence upon the joints, and in such specimens the pale bands of the 

 conuexivnni are very distinct.

This species is quite variable in colors, and somewhat in proportions. 

 Specimens from Cuba and San Domingo are suffused with red and more 

 distinctly pubescent than the others from Texas and Dakota. At the 

 time when w^e described our C. viridicatus, the materials were not at hand 

 in this country to connect the varieties with C. hyalinus, Fab. Speci- 

 mens from the foothills of Colorado, by Lieutenant Carpenter.
