Feltiella spinosa Felt 

 191 1 Felt, E. P. Econom. Ent. Jour., 4:550-51 (Mycodiplosis) 



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. a c e r i - 

 folia and M. p i n i 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 i). The 

 wing is shown on plate 8, figure 9. Type Mycodiplosis 

 V i b u r n i 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.

The unique male was taken June i, 1906 on the common sheep 

 berry. Viburnum lentago, in Washington Park, Albany, 

 N. Y. It has been collected on white pine. Pin us strobus. 

 This species was also taken at North Adams, Mass., August 1907
