Mycodiplosis holotricha Felt 



1908 Felt, E. P. X. Y. State Mus. Bui. 124, p. 401 



The pale yellowish male was reared at Albany in May 1908 from 

 jars containing hickory galls and was supposed to have originated 

 from that produced by C a r y o m y i a holotricha O. S. 

 The species is peculiar on account of the very short loops of the 

 circumfili on the basal enlargement, see figure 80.
