(L. H. Weld). The midge is closely related to T. helianthi 
Brodie from which it may be separated by its smaller size, longer 
stems of the antennal segments of the male and the distinctly longer 
palpi of the female. 
Trishormomyia proteana Felt 
1914 Felt, E.P. Psyche, 20:113 (Hormomyia) 
The midge was collected by C. W. Johnson at Auburndale, Mass., 
May 28th, and is easily distinguished from other large Hormomyias 
by the antennal segments and specially the cylindric basal flagellate 
antennal segments.

This species was reared in early April from galls (fig. 50) on shad- 
bush, Amelanchier canadensis, taken in September 
1907, by Cora H. Clarke at Magnolia, Mass., the deep 
orange larvae deserting the galls in the fall and hibern- 
ating in the soil. It has been recorded from Spring- 
field, Masse and) occurs) about Albany. IN oY: 
Torymus ? ebria O.S5S. has been reared from 
this gall. 
Gall. Length about 5 mm, projecting on the un- 
der side of the leaf, mostly greenish and tapering to 
a deep reddish lipped extremity. The upper surface 
of the leaf is marked by a slightly rounded elevation 
with a thick, whitish, woolly covering. The galls 
Fig. 50 Tris- are monothalamous and may occur singly or in 
hormomyia clusters. 
canadensis, Female. Length 3 mm. Antennae extending to 
lipped _galls_ the third abdominal segment, sparsely haired, yellow- 
on Juneberry ish brown, fuscous basally; fourteen subsessile cy- 
leaf (author’s Jindric segments, the fifth with a length about 
illustration) twice its diameter; circumfila at the basal third, near 
the middle and subapically, the loops with a length 
about equal to one-half the distance between their bases; terminal 
segment reduced, narrowly rounded. Palpi; the first segment stout, 
irregularly oval, the second more than twice the length of the first, 
tapering apically. Face fuscous brown. Mesonotum dark reddish 
brown, the submedian lines sparsely haired. Scutellum dark reddish 
brown, postscutellum reddish; pleurae a variable fuscous orange and
