This species was reared October 8, 1907 from a very small, fusiform, 

 pale green gall occurring mostly on the underside of the terminal 

 leaves of Solidago rugosa and taken by Miss Cora H. 

 Clarke at Tamworth, N. H. A few galls of apparently the same 

 species were received from Miss Clarke from Magnolia, Mass. 

 Similar galls were also sent September 20, 1907 by Mr T. D. Jarvis 

 of Ontario, Canada, and taken by him on Solidago cana- 

 densis. We took this gall on Solidago canadensis at 

 Asheville, N. C, September 29, 1906. 



Gall. This is a minute, fusiform, greenish, or purplish-striped, 

 frequently ribbed gall arising from the underside of the leaf about 

 midway between the midrib and the edge. It is only about 1.6 mm 

 long, a variable greenish and dark brown and sparsely clothed 

 with rather coarse, whitish hairs. See plate 16, figure 1 and also 

 New York State Museum Bulletin 175, plate 1, figure 21 and 21a for 

 illustrations. 



Male. Length 1.75 mm. Antennae about as long as the body, 

 sparsely haired, dark brown; 19 segments, the fifth with a stem 

 three-fourths the length of the basal enlargement, which latter 

 has a length about twice its diameter; terminal segment reduced, 

 narrowly oval and slightly fused with the preceding. Palpi; one 

 slender, irregular segment with a length about four times its dia- 

 meter. Mesonotum dark reddish brown, the submedian lines 

 sparsely haired. Scutellum reddish orange, postscutellum yellowish. 

 Abdomen rather thickly haired, dark brown, the distal segments 

 lighter. Wings hyaline, costa reddish brown. Halteres yellowish 

 basally, light fuscous apically. Coxae and femora basally pale 

 yellowish, the distal portion of femora and tibiae yellowish straw; 

 tarsi a variable reddish or fuscous yellowish. Claws slender, strongly 

 curved, the pul villi as long as the claws. Genitalia; basal clasp 

 segment long, obtusely rounded; terminal clasp segment long, 

 tapering; dorsal plate broad, deeply and triangularly incised; ventral 

 plate long, broadly rounded apically. Harpes short, broad, truncate. 



Female. Length 2 mm. Antennae about two-thirds the length 

 of the body, sparsely haired, fuscous yellowish, basal segment and 

 face fuscous; 17 segments, the fifth with a stem one-fifth the length 

 of the basal enlargement, which latter has a length two and one- 

 half times its diameter; terminal segment produced, tapering, obtuse.
