In the male the basal four joints of the front tarsi are incras- 

 sated and very short, — together scarcely reaching to the apex of 

 the apical process of the tibia. The fifth joint is excessively 

 dilated and as long (without including the claws) as the preceding 

 joints together. One claw is as long as the fifth joint has a very 

 large lamina like appendage at its base and is attached to the 

 apex of the fifth joint in such fashion that it is directed back- 

 wards almost parallel with the tarsus. The other claw is normal. 

 The apex of the basal part of the fifth joint is thickly clothed 

 with long hairs.

I see no reason to separate this species generically from the 

 preceeding although as will be seen by comparing the descriptions 

 the two are not much like each other superficially. The erect 

 (not adpressed) hairs with which it is clothed, its clypeus more 

 evenly rounded in front, its much less transverse prothorax its 

 elytra with distinct traces of costse, its very stout hind tibiae, the 

 much more numerous setse at the apex of each tarsal joint, &c., 

 contribute to make this species extremely distinct from the pre- 

 ceding. Its facies, indeed, is very much that of a Cheiragra, but 

 I do not see how it can justifiably be placed among species with 

 short appendiculate claws while (as is the case) its claws are 

 altogether as characterized in the diagnosis of Cheirrhamphica. 

 Perhaps eventually it may be regarded as the type of a new
