ART. 14 THE CHALCID-FLY GENUS CALLIMOME HUBER 71 



Type locality. — Toronto, Canada. 



Host. — Philonix pezomachoides (Osten Sacken) . 



Type.— C&t. No. 25347, U.S.N.M. 



This species was originally described from three specimens. It 

 is now represented in the National collection by one male type and 

 the head and thorax of a female allotype. I have redescribed it 

 from these specimens. The gall of its host occurs on Quercus alba 

 Linnaeus.
