The length of the pectoral canal and the finely granu- 

 late eyes are the principal diagnostic characters of this 

 genus. In regard to the latter character, however, 

 Lacordaire ascribes the same to Chcetectetorus ; so far as 

 C. bifasciatus* is concerned, he is certainly in error. 

 The distinction, of course, is comparative, but when 

 examined together the difference is very marked.

One of my two specimens is of a dull gray, slightly 

 clouded with brownish; the other is dark brown, almost 

 ap]iroaching to black, a baud, however, in the line of 

 the posterior tubercles, and a large triangular patch over 

 each shoulder, running up to the largo middle tubercle, 

 being gray; the legs also are varied with gray and 

 brown.

* Of the other two species, I am not certain of the correctness of my 

 determination of C. setosus, Boh., and C. spinipennis, Waterh., is unknown 

 to me (the type has disappeared from Mr. Waterhouse's collection).
