in appearance to that made by Asphonclylia monacha 

 O. S. Galls were taken at Jamesburgh, N. J., and West Nyack, 

 N. Y., the latter half of July 1907, adults being reared the 29th 

 and 30th. Some leaves in this material were rolled and it is possible 

 that this species came from these rather than from the galls described 

 below. Apparently the same gall on S. canadensis was col- 

 lected by Dr A. Cosens June 29, 19 16 at Toronto, Can. 



Gall. The gall from which this species may have been reared 

 is a closely adherent pyriform apical leaf gall 1 x .5 cm and identical 

 in every appearance with that commonly producing Asphon- 

 dylia monacha, presumably the normal inhabitant of this 

 type of gall. 



Female. Length 1 mm. Antennae brown, basally yellowish; 

 16 segments, the fifth with a length about one-third greater than its 

 diameter; terminal segment produced, slender, tapering to a narrowly 

 rounded apex. Palpi; first segment short, stout, subquadrate, the 

 second nearly twice as long as the first, narrowly oval, the third as 

 long as the second, slender, the fourth one-half longer than the third, 

 slender; face fuscous yellowish. Mesonotum pale orange. Scu- 

 tellum and postscutellum pale orange. Abdomen light yellowish, 

 the segments sparsely clothed dorsaily with fuscous setae, venter 

 pale yellowish. Wings hyaline, costa dark brown, the third vein 

 uniting with costa at the distal fourth. Halteres yellowish trans- 

 parent. Coxae pale orange, femora mostly light yellowish, tibiae 

 and tarsi mostly dark brown; claws rather long, slender, strongly 

 curved, the pul villi a little longer than the claws. Ovipositor 

 about as long as the abdomen, the terminal lobes long, slender, 

 narrowly rounded. Type Cecid. ai583b.

The single male representing this species was captured on witch- 

 hazel, Hamamelisvirginiana, at Albany, N. Y., June 12, 

 1906. 



Male. Length .75 mm. Antennae dark brown; 18 segments, 

 the fifth with a length about one-half greater than its diameter; 

 terminal segment slightly prolonged, subo void.. Palpi; the first 

 segment short, irregularly subquadrate, the second short, broadly 

 oval, the third a little longer, slender, the fourth one-half longer 

 than the third, more slender. Face presumably dark brown. 

 Mesonotum nearly uniform dark brown, somewhat lighter pos- 

 teriorly, submedian lines rather distinct and ornamented with pale 

 hairs. Scutellum a variable fuscous basally, pale yellowish and with, 

 sparse setae apically, postscutellum dark brown. Abdomen nearly
