The form described as a variety may prove to belong to a different species : we 

 possess only one female of it. 



Ob St — Signor Griffini (Bollett. dei Mus. di Zool. di Torino, xi. p. 30) treats X saltator 

 as a variety of X. fasciatum, and we are inclined to be of the same opinion, the number 

 of spines on the hind femora being variable.
