 pylades and bathyUus in the shape of the valve, and the fact that 

 the aedoeagus is as in the subgenus Phoediniis, instead of a 

 single thoi-n present, as in the balance of the species of the 

 Thorybes group which we have examined. 



It does, however, agree with the others of the Thorybes grouji 

 in that the terminus of the uncus is Ijifurcate.

 Biologia, plate S], fig. 6. 



This species has an extended range from Texas into South 

 America. We have it from Brazil, ]\Iexico, Colombia and 

 Colon, Panama, February 19, 1912, (Williams). 



The aedoeagus of this and the two following species encloses 

 numerous short spines.

The types from Texas are in the Academy Collection. The 

 terminus of the uncus of this species, the two following and 

 caicus is not split, l)ut on the contrary there is a similar single 

 beaked terminus as though che double ends were fused together.
