tpnnns are a little more slender, but as there Is a slight cUfTerence in the antenna; 

 (leprjnding on sex, this is not an obvious character ; they are scarcely longer than 

 the head and thorax, and the outpr joints are closely connected. T.he spurs of 

 the posterior tibice are equal and slender.

 one, and slightly obtuse.

Pennsylvania : Dr. Mel.<heimer. This species resembles closely the preceding, 

 but differs in the o;ray pubescence and in the form of the thorax, which is here 

 longer than wide : the antenn.e are less slender; the spurs of the posterior tibiae 

 appear to be more slender. The head in my specimen is dull black, very ob- 

 scurely sanguineous at the base and on the vertex.

One specimen : Kakabeka Falls, Lake Superior. This species differs from 

 C. pensylvanica in bein;; larger and more finely punctured; the antennre are at- 

 tenuate 1 towards the apex, and the spurs of the posterior tibiae are slender, equal 

 antl slightly obtuse. In the form of the body, which is more robust than C. pen- 

 sylvanica, as well as in the deep emargination of the labrum, it resembles the 

 next species.
