on the basal portion of a grape petiole. Unpublished notes, kindly 

 placed at our disposal by Doctor Howard of the Bureau of Ento- 

 mology, give a number of records of this gall or that of a closely 

 allied form being found on petioles of wild grapevines in Virginia 

 and Missouri. There is also a record in these notes of Proctotrypids 

 having been reared from such galls. 



Gall. The gall and the following description of the larva from 

 which this species was presumably reared, have been drafted 

 by Mr Pergande in the unpublished notes mentioned above, sub- 

 stantially as follows: This gall is an oblong, ovate swelling on the 

 basal portion of the petiole and has a diameter about five or six 

 times that of the petiole. Its length varies from 1.3 to 2 cm. It 

 has the same color as the vine or the petiole. The tissues surrounding 

 the cell, which latter is nearly as long as the entire gall, are woody 

 and rather hard. 



Larva. Length 4 mm, milk white with a dark brown breastbone, 

 the forked apex of the latter protruding from the second segment. 



Female. Length 2.25 mm. Antennae . reddish brown, basally 

 yellowish; 28 segments, the fifth with a length less than its diameter. 

 Palpus, one short, stout segment, obtusely rounded distally. 

 Mesonotum deep reddish brown, evidently denuded. Scutellum 

 yellowish brown, postscutellum a little darker. Abdomen dark 

 reddish brown, the basal segment yellowish or possibly thickly 

 clothed with silvery white scales, the second to sixth segments 

 narrowly margined posteriorly with a fringe of rather long, silvery 

 white scales, ovipositor pale yellowish. Wings hyaline, costa dark 

 brown, the third vein uniting with costa at the distal third; halteres 

 slightly fuscous basally, yellowish white apically. Legs nearly 

 uniform yellowish straw, possibly denuded, the distal segments 

 fuscous; claws long, stout, strongly curved, the pulvilli as long as 

 the claws. Ovipositor about one-half the length of the abdomen, 

 the terminal lobes long, narrowly rounded. Type Cecid. 877. 



Mr Pergande, in unpublished notes placed at our disposal, has 

 characterized the adult, presumably from life, as being dark orange, 

 the mesonotum black with silvery hairs anteriorly and yellowish 

 hairs between the wings. The dorsum of the abdomen is black, 

 the first abdominal segment red, being covered entirely with silvery 

 hairs and segments two to six with black hairs", the latter narrowly 

 margined posteriorly and broadly so laterally with silvery hairs; 

 the venter broadly margined laterally with black hairs.

These midges were taken July 16, 1907 on the office window, 

 Albany, N. Y., presumably having been reared from some recently 

 collected material.
