wings distinct and rather long, pleura pubescent, mcsoplcura spotted 

 with black, scutellum rugose and punctate, each puncture bearing a 

 hair as on head and mesothorax, black at base, fovea? indistinct. 

 Abdomen smooth, shining, faintly punctate, all the segments clothed 

 with long, straight, pale yellowish pile, but dorsally and laterally bare 

 in spots, rotund but ridged dorsaliy, 2nd segment occupying half its 

 length, 3rd and 4th segments also wide, ventral valve large, triangular, 

 with broad apex, bearing a large tuft of hairs, dorsal valve also hairy at 

 tip. Legs pale brown and clothed with hairs. Wings large, hyaline, 

 pubescent, veins brownish, black, subcostal, radial, anal and cross 

 veins thickened, the radial vein incrassate at tip, radial cell open and 

 rather short, vein at base angulate and clouded, areolet large and dis- 

 tinct, cubital vein reaching almost to basal, clouded area at base of 

 cubital and discoidal cells and at break in anal vein, the cubital cell 

 with 12-15 black spots. Length 4.5 mm. 



Gall. Small, dark brown, globular galls in clusters of ten to twelve 

 on terminal twigs of Qucrcus lobata, 8 mm. in diameter, more or less 

 irregular in shape due to compression, the exposed surface rugose. 

 Monothalamous, the small, round larval cell, 2 mm. in diameter, 

 imbedded centrally in spongy tissue. 



Habitat. Palo Alto, Cal. (Miss Bertha Wiltz). Kern 

 County, California. (Beutenmuller.) 



Beutenmuller describes the gall of this species as "covered 

 with a dense, short and compact woolly substance and hairs." 

 He states also that it occurs on leaves. His specimens are 

 obviously different from mine, although specimens of the fly 

 from my collection which he has compared with those in his 

 possession, he states are similar.
