Mycodiplosis cucurbitae Felt 
1911 Felt, E. P. Econom. Ent. Jour., 4:550 
One female was obtained in association with _ Itonida cucur- 
bitae, from which it can hardly be separated with a hand lens. 
It is recorded as having been reared July 10, 1876 from orange 
larvae on a squash, presumably by the late C. V. Riley, and was 
described through the courtesy of Dr L. O. Howard of the United 
States Bureau of Entomology. The affected squash had a curious, 
rough, fulvous appearance.

The claws not bent at right angles, the anterior unidentate and 
the binodose antennae of the male with three well-developed circum- 
fili indicate a relationship with Mycodiplosis Rubs. and its allies, 
from which it is easily separated by the triarticulate palpi. It is 
readily distinguished from Xyphodiplosis Felt by the terminal clasp 
segment not being greatly produced and the short, broad ventral 
plates wly.pe DWercoccd Felt.
