This pale yellowish species was reared August 5, 1908 from a woolly, 

 oval leaf gall on the lateral veins of shadbush, Amelanchier 

 canadensis, taken by Cora H. Clarke at Coolidge Point, 

 Magnolia, Mass., the last of the preceding June. Two Curculionids 

 were also reared from these galls, namely, Tachypterus quad" 

 rigibbus Say and Pseudanthonomus crataegi 

 Walsh. This gall midge is easily separable from allied forms by 

 the long, broadly and roundly emarginate ventral plate, in con- 

 nection with the produced stems of the fifth antennal segment and 

 the form of the ventral plate. 



Gall. Length i to 1.5 cm, an oval swelling on the lateral veins 

 (fig. 35), with a yellowish discoloration and small slit on the upper 

 surface and a broadly rounded, white, woolly, swelling beneath.
