Dec, 1919.] Felt: New Gall Midges from the Adirondacks. 279 



The coloration of the male is presumably very similar to that of 

 the female. At least no differences were noted prior to the making 

 of the microscopic preparations. 



Konisomyia borealis new species. 



The female described below was taken by Mr. Howard Notman at 

 Keene Valley, September 14, 1917. It is closely related to K. fusca 

 Felt, from which it may be separated by differences in color and size 

 and especially variations in antennal structure. 



Female. — Length 1.5 mm. Antennae hardly extending to the base of the 

 head, sparsely haired, dark brown, probably nine segments, the second some- 

 what enlarged, the fifth with a length a little greater than its diameter, the 

 terminal segment produced, evidently compound and with a length about three 

 times its diameter. Palpi ; first segment irregularly quadrangular, the second 

 z little longer, irregular, the third a little longer and stouter than the second, 

 the fourth one half longer than the third and somewhat dilated. Eyes black. 

 Mesonotum dark reddish brown. Scutellum and postscutellum dark brown. 

 Abdomen dark yellowish brown, darker apically. Wings hyaline and nearly as 

 in K. fusca except that the fork of the fourth vein is a little shorter and some- 

 what broader. Plalteres fuscous yellowish. Legs a nearly uniform dark yel- 

 lowish brown. Claws moderately stout, strongly curved. The pulvilli nearly 

 as long as the claws. Ovipositor short, stout, the lobes triarticulate, the ter- 

 minal segment broadly rounded and sparsely haired. There is in this species 

 as in K. fusca submedian globose appendages ventrally on the eighth abdominal 

 segment. Type C. 1700. 



Neptunimyia flavida new species. 



This midge was taken August 25, 1917, by Mr. Howard Notman 

 at Keene Valley, N. Y., and is tentatively referred to this genus, 

 though in the type species the third vein joins costa near the distal 

 fourth and the fourth vein is distinct, while in this new form the third 

 vein is well separated from costa, uniting with the margin near the 

 apex of the wing and the third vein is very indistinct. However, 

 antennal characters and the rather thickly haired wings indicate 

 affinities with Neptunimyia and the species is therefore tentatively 

 placed in this genus. 



Female. — Length 1 mm. Antennae extending to the third abdominal seg- 

 ment, thickly haired fuscous ye'lowish, 10 segments, the fifth with a stem a 

 little longer than the somewhat pyriform basal enlargement, which latter has 

 a subbasal whorl of stout setae, a smaller subapical whorl of similar setae and
