Swezey bred a number of males and females, determined as 

 above by Ashmead, from cocoons obtained from the Fulgorid, 

 Onuciiis pruinosa. He rightly concluded that they were sexes of 

 one species, as was subsecjuently confirmed by breedings hun- 

 dreds of both sexes from icocoons sent from N. America by 

 Koebele. Copulation was observed on many occasions. The 

 males retained by Swezey do not in any way agree in the struct- 

 ure of the antennae with Ashmead's description of these parts 

 in the original example of Labco typhlocybac, bred by Riley from 

 a Typhlocyba on Ccltis. Tf that description is correct, it is not 

 only utterly impossible that the type of L. typhlocybac can be- 

 long to the same species as the male of Dryinus oinciiidis, but 

 further, it cannot be placed in the same genus in my opinion.
