NEW GALL MIDGES. 



BY E. P. FELT, ALBANY, N. Y. 



Below are given descriptions of a miscellaneous lot of gall 

 midges showing a varied food habit and originating in widely 

 separated portions of the world. 



Dasyneura sassafras, n. sp. 



The midge described below was reared by W. A. Ross, August 

 12, 1915, from larvae curling sassafras foliage at Gordon, Ont., 

 and submitted for identification by Arthur Gibson, Chief Assistant 

 Entomologist of the Department of Agriculture, Ottawa, Can. 

 The species runs in our key to D. apicata Felt, noticed in detail 

 on page 152 of New York State Museum Bulletin 175. It is easily 

 separated from this form and also the somewhat similar Dasyneura 

 smilacifolia Felt by structural and colorational characters. 



Female — Length .75 mm. Antennae extending to the second 

 abdominal segment, sparsely haired dark brow^n; 16 sessile seg- 

 ments, the fifth with a length two and one-half times its diameter, 

 the terminal segment compound, with a length four to five times 

 its diameter and a more or less distinct constriction near the 

 middle. Palpi; first segment subquadrate, irregular, the second 

 with a length more than twice its diameter, the third a little longer 

 than the second, more slender, the fourth one-half longer than 

 the third, more slender. Mesonotum light yellowish brown, the 

 submedian lines and scutellum yellowish, postscutellum reddish 

 yellow.' Abdomen sparsely haired, pale yellowish. Wings hyaline; 

 hal teres pale yellowish. CoxcC and femora mostly pale yellowish, 

 the distal portion of femora, tibiae and tarsi dark brown, the tarsi 

 almost black; claws slender, strongly curved, the pulvilli nearly as 

 long as the claws. Ovipositor pale yellowish, fuscous apically, as 

 long as the abdomen, the terminal lobes with a length nearly four 

 times the width, broadly rounded and sparsely setose apically. 

 Type Cecid. a2676. * 



Dasyneura gossypii, n. sp. 



The small midges described below were forwarded under date 

 of July 7, 1915, by Prof. T. Bainbrigge Fletcher, Imperial Ento- 

 mologist of the Agricultural Research Institute, Pusa, Bihar,
