great difference in colour, the sliglitly porrect clypeus, the 

 slightly broader pygidial area, and the shorter petiole are 

 quite sufficient distinctions.

Chjtemnestra having been used by Dana for Crustacea in 

 1847, it cannot be used here. 



I cannot see that Smith's genus is distinct from Spinola^s, 

 the tubercle on the second ventral segment of the male 

 being almost the only good character for separation. The 

 statement of Ashmead that the anterior tarsi in the female 

 of Miscothyris are without a comb is entirely erroneous. 

 As I understand the genus, it would include Handlirsch^s 

 groups bipunctatus, chilensis, and thoracicus. The type of 

 Cliteinneslra is gayi, Spin. The genus is only represented 

 in America and Australia. Handlirsch includes it in 

 Gorytes in his revision of that genus, but I think it is more 

 convenient to treat it as a separate genus. 



I have not seen M. megalojihthalmus, Handl., but, according 

 to Handlirsch, both recurrent nervures are received by the 

 second cubital cell, though in other points it is nearly
