latter has a length one-half greater than its diameter and is thickh 
clothed with a long, stout, strongly curved setae; fourteenth seg 
ment reduced, the fifteenth long, slender, swollen basally. Palpi 
first segment short, irregular, the second with a length about thric 
its diameter, the third and fourth, each subequal, about one-hal 
longer than the second, the fourth somewhat dilated. Thorax anc 
abdomen a variable yellowish brown. MHalteres yellowish. Leg: 
mostly fuscous yellowish; the first tarsal segment, the base and thi 
apex of the second, the apex of the third and fourth broadly whit 
margined, the fifth white. In some specimens the basal bandiny 
of the second tarsal segment is much reduced. Claws slender 
strongly curved, the anterior unidentate. Ovipositor short, stout 
the terminal lobes broadly oval and thickly setose. Type Cecid

Members of this genus have the anterior tarsal claws unidentate 
and may be separated from the allied Mycodiplosis by the more o1 
less conspicuous, setose or nearly glabrous basal lobe at the internal 
basal angle of the basal clasp segment. The ventral plate in the 
type species is as long as the style and broadly rounded apically, 
while the harpes are strongly chitinized. Type Mycodi plosis 
lobata Felt.
