Galls of this species were sent me by Mr. Trevor Kincaid, of Olympia, 

 Washington, who writes that they were collected from the twigs of 

 Qiiercus garryana. The galls are ellipsoids, from 5 to 7 mm. in greatest 

 diameter; they are smooth, monothalamoiis and snuff coloured, both 

 externally and internally, and are attached by a small projection to the 

 side of small twigs. A few specimens that appear not to be mature are 

 greenish in colour, and have shrivelled somewhat on drying, so that the 

 surface is covered with small, shrunken areas. The substance of the 

 gall is uniformly and densely cellular. Described from 13 galls. 



Gall-fly. — General colour a dark brown, inclined to black. Head 

 small, blackish in colour, tinged with rufous ; antennae of the same colour 

 as the head, 14-jointed, 3rd joint once and a-half as long as the 4th. 

 Thorax finely rugose and rather coarsely punctured, ]iarapsidal and 

 median grooves distinct near the scutellum, the former extending half way 

 to the collar, the latter less than half way. The two parallel lines 

 extending back from the collar and the lines over the bases of the win^s 

 are the blackest parts of the mesothorax. Scutellum rugose, fovese 

 scarcely discernable ; pleura? finely punctured, the punctures giving rise to 

 hairs ; colour of pleurae rufous. Abdomen, except a large patch on the 

 dorsum of the 2nd segment and a narrow line over the succeeding 

 segments, densely set with silky pubescence, the hairs rising from minute 

 punctures. Wings hyaline, 5 mm. long, nervures slender, radial area long 

 and narrow. Feet of a light chestnut colour, the tarsi being darkest, 

 densely set with a fine pubescence. Length, 4 mm. 



Described from one bred female.

Galls of this species were also sent me by Mr. Kincaid, who writes 

 that he took them from limbs of Q. garryana. They are polythalamous, 

 globular, buff-coloured galls measuring from 3 to 5^ cm. in diameter; 

 some of the galls are tinged with salmon. The galls grow in clusters on 

 the limbs, and are in some cases much pressed out of shape. Perfectly
