REPORT OF THE STATE ENTOMOLOGIST I915 1 55 



Male. Length 2 mm. Antennae extending to the fourth abdom- 

 inal segment, sparsely haired, dark brown; 14 segments, the fifth 

 with a length about four times its diameter, about eight low cir- 

 cumfili. Palpi; the first segment short, stout, subquadrate, the second 

 with a length about three times its diameter, narrowly oval, the 

 third a little longer, more slender, irregular, the fourth a little longer 

 and more slender than the third. Mesonotum dark reddish brown, 

 the submedian lines sparsely haired. Scutellum and postscutellum 

 fuscous yellowish. Abdomen sparsely haired, dark brown, the mem- 

 brane and pleurae pale orange; genitalia fuscous. Wings hyaline, 

 costa dark brown; halteres yellowish. Legs mostly dark brown; 

 claws long, stout, strongly curved, simple, the pul villi about two- 

 thirds the length of the claws. Genitalia; dorsal plate short, broad, 

 deeply and triangularly incised, the lobes short and roundly taper-

This Species was erected for a m.ale which the late Dr M, T. 

 Thompson supposed he had reared from a conic leaf gall on hickory, 

 the latter being considered identical with that of Cecidomyia 

 sanguinolenta O. S. It is very probable that this is an 

 error, since all species of Cincticornia known to us have been obtained 

 from oak galls. 



Male. Length 3 mm. Antennae extending to the third abdominal 

 segment, sparsely haired, pale yellowish; 13 segments, the fifth with 

 a length twice -its diameter; 10 low anastomosing circumfili; terminal 

 segment produced, slightly expanded and with an apical knob. 

 Palpi; the first segment with a length twice its diameter, the second 

 broadly oval, the third a little longer than the second, slender, the 

 fourth one-half longer than the third. Face fuscous yellowish. 

 Mesonotum probably fuscous brown, the scutellum and postscutellum 

 presumably yellowish or yellowish orange, the abdomen probably 

 reddish brown. Genitalia fuscous. Wings hyaline, costa light brown. 

 Halteres probably pale yellowish. Legs yellowish brown ; claws long, 

 stout, strongly curved, the pulvilli a little shorter than the claws. 

 Genitalia; dorsal plate short, broad, broadly and triangularly emargi- 

 nate. Type Cecid. 11 14. 



Cincticornia quercifolia Felt 

 1908 Felt, E. P. N. Y. State Mus, Bui. 124:380 



This was reared in the bureau of entomology from a flat gall on 

 red oak, Quercus rubra, leaves collected in the District of 

 Columbia, adtilts appearing April i to 27, 1896.
