Although the form of the front of this species is nearly thai of Cryptohypnus Bilaceip 

 the shape of the posterior coxae, and the parallel Bides of the prosternum, prevent its as- 

 sociation with that species.

Lake Superior, not raro. This species differs from the description given ofmedianus 

 Germ. (Zeitsch. 1,71) by the impunctured elytral striae. The form of the bod} is as in the 



preceding; the third joint of the antenna' is a little longer than the second, bul both 

 together are not longer than the fourth.

Two specimens found at Ann Arbor, Michigan. Germar describes the strias of the 

 elytra as punctured; in one specimen they appear smooth, in the other they arc feebly 

 punctured; the female does not differ in form from the preceding species; the male has 



the apex of the elytra produced and acute. The third joint of the antennas is one-hall' 

 longer than the second.

Lake Superior, Harbour; found also in Western New York. The less densely 



punctured thorax will distinguish this from the othei of this group. The third 



joint of the antennae is shorter than the fourth, although longer than in the preceding 



: by this character it forms a transition to C. hieroglyphicus. In mj catalogue of 



Lake Superi cts, this is erroneously placed as EI. curialus Say.
