The small, reddish brown species described in the above citation 
was labeled as having been reared from oaks without any indication 
as to locality or date. The species was received from the Bureau: 
of Entomology, Washington, D. C., and is described through the 
courtesy of Doctor Howard. It is closely allied to M. aceri- 
folia and M. pini from which it is easily separated by the 
longer basal portion of the fifth antennal segment in the male.

The midges referable to this genus are small, yellowish, brown- 
banded, allied to Lobodiplosis Felt and easily distinguished by the 
unique genitalia. The stout, basal clasp segment bears a broadly 
dilated, subfusiform terminal clasp segment. The harpes are 
strongly chitinized and very complex (plate 12, figure 1). The 
wing is shown on plate 8, figure 9. Type Mycodiplosis 
viburni Felt. The larvae are presumably predaceous on 
aphids and mites. 
In the female of the type species the stem of the fifth antennal 
segment is one-half the length of the cylindric basal enlargement, 
which latter has a length about three and one-half times its diameter. 
The ovipositor is short, stout, with a length about one-fourth that 
of the abdomen, the terminal lobes tapering to a narrowly rounded, 
setose apex. Near the posterior ventral angles of the dorsal sclerite 
there is a peculiar filamentous, circular, chitinous structure with a 
diameter about one-half the width of the basal portion of the 
Ovipositor.
