MAY FLIES AND MIDGES OF NEW YORK 305 



in some lights shining cinereous ; black bristled, especially on the 

 sides in front of the wings; scutellum obtuse, black bristled. 

 Abdomen black and black-haired, the anal segment obtuse, flat- 

 tened (after death), the appendages bearded. The wings cinereous 

 whitish, toward the costa somewhat infuscate, the tip hairy, espe- 

 cially in the radial cell, the remaining surface nearly bare; the 

 posterior margin ciliate. Halteres fuscous black. The legs fus- 

 cous black and long-haired except the fore tibiae and tarsi, which 

 are short pilose; fore metatarsus one third shorter than its tibia. 

 Female. Tne thorax and abdomen with pale setae, the wings 

 somewhat hairy; the halteres fuscous black or sometimes pale 

 fuscous. Length 3 to 4 mm. Holmgren, loc. cit. (Greenland, 

 Lundbeck.) 



Lundbeck (1898 p.284) in a note states, " The wings are very 

 sparsely haired and only toward the apex, the wing of the female 

 being a little more hairy between the branches of the radius 

 than that of the male. The hairs seem to rub off readily, and 

 hence many specimens are found with only a trace."

Black, not shining; the anal segment of the male wider than 

 the preceding one. Forceps small, its arms rather robust. Palpi 

 and antennae black, the hairs of the latter sometimes tinged with 

 brown. Legs black, or pitchy; fore metatarsus about one half as 

 long as its tibia. Wings pale brownish or whitish according to 

 the incidence of the light ; the hairs dark, more perceptible at the 

 tip ; fork of the cubitus distad of the small crossvein. Halteres of 

 the male black, of the female pale. Length 3 to 4.5 mm. Schiner 

 and V. d. Wulp, loc. cit. (Greenland, Lundbeck.) 



The species described by Zetterstedt appears to be different, 

 judging from the different relative lengths of fore tibia and 

 metatarsus.
