evenly curved, the pulvilli shorter than the claws. Genitalia; basal clasp segment 

 long, moderately stout; terminal clasp segment short, stout; dorsal plate short, 

 deeply and triangularly emarginate, the lobes truncate or very broadly emarginate 

 and sparsely setose; ventral plate long, broad, broadly and roundly emarginate, the 

 lobes short, narrowly rounded; style long, slender. 



Female. Length 2.5 mm. Antennae extending. to the fifth abdominal segment, 

 sparsely haired, fuscous yellowish, yellowish basally; 14 segments, the fifth with a 

 stem thi-ee-fourths the length of the cyUndric basal enlargement, which latter has a 

 length thrice its diameter and shghtly constricted near the basal thu'd; terminal 

 segment, basal enlargement with a length thrice its diameter, the appendage stout, 

 fingerlike. Palpi; first segment irregular, short, the second with a length nearly 

 thrice its diameter, the third as long as the second and the fourth about one-thu-d 

 longer than the third. Face yellowish. Mesonotum reddish brown, the submedian 

 lines fuscous yellowish, sparsely haired. Scutellum and postscutellum mostly deep 

 red. Abdomen pale yellowish orange. Halteres pale yellowish, the knob reddish. 

 Coxae yellowish; femora and tibiae fuscous straw, the tarsi darker, the pulvilli 

 nearly as long as the moderately stout claws. Ovipositor yellowish, stout, about 

 one-half as long as the abdomen; terminal lobes lanceolate and sparsely setose. 

 Cecida 2252. 



Prodiplosis fitchii n. sp. 



The specimens described below were found in association with larvae 

 and shrunken wheat kernels in the New York State collections, la- 

 beled "wheat midge" in the handwriting of Doctor Fitch and in all 

 probability date back to the serious outbreaks of this insect studied 

 by him, particularly as the color characters agree closely with his 

 excellent account of this insect. We prefer to regard this species 

 simply as one of the destructive forms, though it may possibly be 

 only an associated midge. Though the specimens are in poor condi- 

 tion, the insect is tentatively referred to the above genus and charac- 

 terized in the hope that its description will aid in establishing the 

 identity of the midges injurious to American wheat. 



Male. Length 1 mm. Antennae fully one-half longer than the body, thickly 

 haired, whitish; 14 segments, the fifth binodose and having the stems respectively, 

 two and one-half and three times their diameters. Distal node slightly produced, 

 with a length one-fourth greater than its diameter; circumfili apparently rudiinent- 

 ary or wanting. Distal segments possibly binodose, wanting. Palpi; first and 

 second segments probably short, the third with a length about four times its diameter, 

 the fom-th a little longer than the third, narrowlj' oval. Face pale yellowish trans- 

 parent, eyes large, coarsely gi-anulate, black. Body a nearly uniform pale yellowish, 

 the scutellum, pleurae and tip of abdomen pale yellowish orange. Wings hyaline, 

 somewhat whitish. Halteres and legs mostly whitish. Genitalic structure indis- 

 tinct, apparently similar to that of P. floricola Felt. 



Female. Length 1.25 mm. Antennae probably nearly as long as the body, sparsely 

 haired, whitish; 14 segments, the fifth with a stem three-fourths the length of the 

 cylindric basal enlargement, which latter has a length two and one-half times its diam- 

 eter and sparse whorls of long, slender setse subbasally and apically. Mesonotum 

 yellowish. Abdomen pale yellowish white. The ovipositor stout, apparently with 

 a length about half that of the abdomen; terminal lobes missing. Claws slender,
