REPORT OF THE STATE ENTOMOLOGIST I918 183 
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 1 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.
