Cubitus of hiuil wing originating beyond the

2. First recurrent nervure received close to the

Both recurrent nervures received by the second

Genus Miscothyris, Sm.

 Dana). 



Clytemuestra having been used by Dana for Crustacea in 

 1847, it cannot be used liere. 



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 lor separation. The 

 statement of Ashmcad that the anterior tarsi in the female 

 of Miscothyris are without a comb is entirely erroneous. 

 As 1 understand the genus, it would include Ilandlirsch's 

 groups hipunctulus, chilensis, and thoracicus. The type of 

 ('l.itemnestra is gayi, Spin. The genus is only represented 

 in America and Australia. Handlirsch includes it in 

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

 convenient to treat it as a separate genus. 



I have not seen M. meyalophthabnus, Ilandl.^ but, according 

 to Handlirsch, both recurrent nervures are received by the 

 second cubital cell, though in other points it is nearly
