Trishormomyia shawi Felt 
1913 Felt, E. P. Psyche, 20:145 (Hormomyia) 
This species is separated from the allied T. consobrina Felt 
by colorational characters and the extremely slender second palpal 
segment. It was received from C. W. Johnson of the Boston 
Society of Natural History and labeled: “‘ VIII-20, 1909, Hampton, 
Ne 69.7. SAW, 117. 
Trishormomyia saturni Felt 
1914 Felt, E.P. N.Y. Ent. Soc. Jour., 22:133 (Hormomyia) 
The midge was taken August 24, 1909, by C. P. Alexander in th® 
Adirondacks, altitude rs40 feet. It may be separated from the 
related T. shawi Felt by the darker abdomen and the distinctly 
longer stems of the flagellate antennal segments. 
Trishormomyia fenestra Felt 
1915 Felt, E. P. Can. Ent., 47:231-32 (Hormomyia) 
The midge is closely related to T. shawi Felt, from which it is 
easily distinguished by marked differences in color characters and 
in the structure of the basal clasp segment. Both sexes were taken 
by C. P. Alexander, August 22, 1910, at Woodworth’s Lake, Fulton 
aay 
county, N. Y.
