The midge, previously unknown, produces a subgobular, yel- 

 lowish gall, about the size of a large pea, on Helianthus leaves. 

 The deformities are about equally prominent on both sides of the 

 leaf and located irregularly, though usually near the mid rib. This 

 species has been recorded from the Province of Ontario by the late 

 Dr. Brodie, and has been reported as common at Evanston, 111., 

 by Mr. L. H. Weld, who reared the adults described below, July 

 23, 1907, and who states that the gall occurred commonly at North 

 Evanston, 111., on plants growing in a deep, black, rich soil along 

 with compas plants. The gall of H. helianthi Brodie Mr. Weld 

 reports as very local at Evanston, 111., it being found by him in 

 September, whereas the gall of H. bulla occurs in July. Unfor- 

 tunately, the account by Walsh gives only an incidental mention 

 of the gall of H. bulla, and we are therefore unable to credit him 

 with having characterized the species. The midge is closely allied 

 to H. helianthi Brodie, from which it may be readily separated by 

 its smaller size, longer stems of the antennal segments in the male, 

 and the distinctly longer palpi of the female. 



Male. — Length 1.5 mm. Antennae extending to the third ab- 

 dominal segment, sparsely haired, pale yellowish; 14 segments, the 

 fifth with stems \}^ and 1^ times their diameters, respectively; 



August, 1014.
