and roundly emarginate ; the lobes divergent and narrowly rounded ; ventral 

 plate long, moderately broad, broadly and roundly emarginate, both sparsely 

 setose. Type Cecid. 1753. 



Mycodiplosis intermedia new species. 



This species was taken by Mr. Howard Notman August 31, 1917, 

 at Keene Valley, N. Y. It is closely related to M. ccstiva Felt, from 

 which it is easily distinguished by the narrower ventral plate and the 

 distinctly irregularly rounded lobes of the dorsal plate. It is separa- 

 ble from M. obscura Felt by the distinct constriction of the basal 

 third of the distal enlargement of the fifth antennal segment and the 

 distinctly broader ventral plate. 



Male. — Length 1 mm. Antennae J /> longer than the body, thickly haired, 

 fuscous yellowish, 14 segments, the fifth having stems with a length 3 and 3J/2 

 times their diameters respectively. The distal node with a length 1 54 its 

 diameter and distinctly constricted at the basal third. Palpi : first segment 

 short, irregular, the second more than twice the length of the first, the third 

 a little longer, more slender and the fourth Y\ longer than the third and more 

 slender. Mesonotum yellowish brown. Scutellum and postscutellum fuscous 

 yellowish. Abdomen mostly dark brown, the basal segments and genitalia 

 fuscous yellowish. Halteres and coxae whitish transparent. The legs mostly 

 light straw. Claws long, strongly curved, slender, the anterior unidentate, the 

 pulvilli about Yz the length of the claws. Genitalia : basal clasp segment mod- 

 erately long, slender ; terminal clasp segment moderately stout ; dorsal plate 

 short, deeply and narrowly incised, the lobes broad, irregularly rounded and 

 sparsely setose; ventral plate long, moderately broad, roundly emarginate 

 apically. Type Cecid. 1784. 



Mycodiplosis lenis new species. 



This species was taken August 13, 1917, at Keene Valley, N. Y., 

 by Mr. Howard Notman. It is closely related to M. robusta Felt, 

 from which it is most easily separated by the markedly different color 

 characters, the distinctly less produced internal angles of the lobes 

 of the dorsal plate and the longer stems of the fifth antennal segment. 



Male. — Length 1 mm. Antennae twice the length of the body, thickly 

 haired, fuscous yellowish, 14 segments, the fifth having stems with a length 3 

 and z T A times their diameters respectively, the distal enlargement with a length 

 over y 2 greater than its diameter and distinctly constricted at the basal third ; 

 terminal segment greatly produced, the basal portion of the stem with a length 

 five times its diameter, the distal enlargement cylindric, with a length four 

 times its diameter and apically with a long finger-like process. Palpi: first
