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 Entomolog}^ The affected squash had a curious, 

 rough, fulvous appearance. 



DIADIPLOSIS Felt

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 

 plate. Type D . cocci Felt.
