M. Perroud's type {T. fJiformis) appears to be a much 

 narrower insect, and to differ in other respects from the 

 species described below. In my original description, I 

 have conveyed an impression which I did not mean to 

 convey, and to which M. Lacordaire has taken a just ex- 

 ception, I have said that the coxae of the intermediate 

 legs are " unusvially large, and placed so apart, that the 

 insertion of the femora can be almost seen from above ; " 

 it should have been that they ai'e extended so much 

 towards the sides, that the insertion of the femora can be 

 almost seen from above. The genus is an abnormal one 

 even in this sub-family.
