 horizontally they are of the same length.

This genus includes the larger species of the group Miopteriges. Although occa- 

 sionally very elongate and slender, the body is somewhat more robust than in the other 

 genera. The spines of the anterior tibiae are generally very regular, but they are 

 sometimes unequal in length ; the innermost spine is placed in its usual position, and 

 is not transferred upwards to near the insertion of the claw as in Mionyx. 



To this genus belong the following species '.—Thespis conspersa, Sss. (South 

 America) ; vicina, Sss. (Colombia) ; and 1 infumata, Serv. (Brazil).
