but especially to C. lapidicolus, from which, however, it 

 differs in its markings more than C. lapidicolus does from 

 C.maculatus. The ground-color is reddish brown, and the 

 spots which make up the mottling are distributed more 

 regularly than in the preceding. It differs from it further 

 in the greater length of the antennas, and in the presence 

 of spines upon the under side of the hind femora ; these 

 are spined both upon the inner and outer edge, those of 

 the inner edge being minute, regularly arranged, and of 

 equal size, while those of the outer edge to the number of 

 5-8 only, are much larger, longer, of unequal length, and 

 irregularly arranged. As the only female I have seen 

 wants the hind femora, I cannot tell whether the males 

 and females differ in the character of these spines as is the 

 case in some species. The hind legs of this species are 

 proportionally longer than in any previously mentioned. 



Average length of body .65 inches ; average length hind 

 femora .70 inches ; length of antennae about Ih inches ; 

 length of ovipositor .35. Z $ 1 9 .

This is the only described species of the genus which 

 I have not seen. The darker portions of the hind femora 

 of all the species have scabrous surfaces.

6. C. DIVERGENS, UOV. Sp. 



A species recalling C. lapidicola by its coloration and 

 markings, which in general appearance it much resembles, 

 but from which, as from all others I know, it may be dis- 

 tinguished by the peculiar disposition of the spines upon 

 the posterior tibia?, which, in addition to the row of min-
