This dark brown species was reared July 11, 1907 from the 

 folded terminal leaves of rose taken at Albany, N. Y. The insects 

 reared agree so closely with the description of the above named 

 European species that they have been provisionally identified there- 

 with. Tory mus ostensackenii D.T. was reared from 

 this midge. 



Gall. The three terminal leaflets of the branch are folded to- 

 gether longitudinally and containnumerous white larvae. The gall 

 is greenish tinged with brown and about 18 mm long. The general 

 appearance is very similar to the illustration given by Connold in 

 his Vegetable Galls. 



Female,. Length 2 to 2.5 mm. Antennae extending to the fifth 

 abdominal segment, sparsely haired, fuscous yellowish ; 14 seg- 

 ments, the fifth with a stem about one-fourth the length of the basal 

 enlargement, which latter has a length about twice its diameter; 

 terminal segment reduced, broadly oval. Palpi; the first segment 

 short, stout, subquadrate, the second more than twice the length of 

 the first, more slender, the third a little longer and more slender 

 than the second, the fourth a little shorter than the third. Heac 

 slightly reddish. Mesonotum dark brown, the submedian lines 

 sparsely haired, fuscous orange. Scutellum fuscous yellowish, post- 

 scutellum lighter. Abdomen sparsely clothed with fine hairs, dark 

 brown, the incisures and venter dark salmon. Wings hyaline, costa 

 light brown; halteres yellowish basally, fuscous apically. Legs a 

 uniform dark brown, femora pale beneath; claws long, slender, 

 strongly curved, the pulvilli a little longer than the claws. Ovi- 

 positor pale salmon, about half the length of the abdomen, the 

 terminal lobes long, slender, narrowly oval. Cecid. ai49i.

The work of this species has been known for several years. 

 The late Dr James Fletcher called the writer's attention to the fact 

 that a noted botanist described the distorted fruits produced by this 

 species as the natural production of Viola dicksonii. This 

 species is evidently widely distributed, since it is usually present 

 though not abundant, according to the late Doctor Fletcher, in the
