"Gall. An irregular, inflated, hard, woody gall, over an inch long 

 and about half an inch in diameter, issuing from a slit in a terminal twig 

 of Quae us ckrysolepis var. vaccinifolia; polythalamous. 



"Gall-fly. Female. Length, 3.4 mm. This species, in color and 

 size, closely resembles //. ficigera, Ashmead, but differs as follows: 

 The 14-jointed antenna?, except the first two joints, pleura, and meta- 

 thorax blackish, shining; the rest of the insect — except the dorsum of the 

 second abdominal segment, which is obfuscated — brownish yellow; the 

 head and thorax punctate, and covered with a glittering white pube- 

 scence. Abdomen highly polished, bare, except the sides of second 

 segment basally; spine of ventral valve short, stout, hairy. Wings 

 hyaline, veins brown, areolet distinct, cubital cell open at base, while 

 the basal vein of radial cell is only obtusely angular. 



"Type No. 3080, U. S. N. M. 



"Two specimens, reared December 6th, 1880, from galls 

 collected by Prof. J. H. Comstock, in California, October 16, 

 1880." (W. H. Ashmead.) 

 ■ I have not seen examples of this species.

 (1909). p. :;s. 



Female. Testaceous, eyes, ocelli, occiput, anterior margin of face, 

 antennae distally from 8th segment, pecten, dorsal and subdorsal vitta?. 

 on mesonotum concurrent with median longitudinal lines and lines over 

 base of wings, median vitta on metanotum and dorsal valve black, 

 vertex and front of head, tibiae and tarsi of legs, and abdomen dorsally 

 fuscous. Head faintly rugose and covered with dense grayish pube- 

 scence, antenna- 14-segmented, 1st and 2nd segments stout, 2nd a trifle 

 longer than broad, 3rd segment longest, longer than 1 and 2 together, 

 4th segment as long as 3rd, succeeding segments to Kith progressively 

 shorter, lilth and following segments subequal except the last, which is 

 somewhat longer than penultimate; all the segments sparsely pubescent. 

 Thorax coarsely punctate and covered with pubescence, parapsidal 

 grooves on mesonotum indistinct, median longitudinal lines reaching 

 half-way to posterior margin, smooth lines over base of wings distinct, 

 scutellum rugose, fovea? inconspicuous, long, narrow and oblique. 

 Abdomen smooth and shining, much compressed, 2nd segment reaching 

 half-way to apex, pubescent at base. 3rd, 4th and 5th segments fairly 

 broad, dorsal and ventral valves thickly pubescent. Wings hyaline, 

 pubescent, veins heavy, black .radial cell long, open at the margin, vein 

 at base of cell decidedly angulate, radius itself almost straight, areolet 

 rather large, cubitus not quite reaching basal nervure. Claws simple
