about 1.35 as long as second segment; otherwise structurally similar 

 to female of punctatum, but possibly a little less strongly punctate. 



Black. Colored as in punctatum except that legs are a little paler 

 fulvous, apical 0.12 ± of hind femur strongly infuscate, hind tibia 

 entirely fuscous, hind tarsus dark fuscous, and front and middle 

 tibiae infuscate apically. 



Specimens (18 d 1 , 109): From Maine (Bangor, Echo Lake on 

 Mount Desert, and Orono); Michigan (Presque Isle Co.); Minnesota 

 (Basswood Lake in Lake Co.); New Hampshire (Franconia, Mount 

 Madison, and Pinkham Notch); New York (Bemus Point, Boreas

Male: Front wing 4.5 to 9.5 mm. long; first segment of flagellum 

 about 1.4 as long as second segment; all segments of flagellum unusually 

 short and stout; punctures on mesoscutum small, separated by about 

 2.5 their diameter; propodeal teeth about as long as their basal 

 width; punctures on front and hind faces of hind femur separated 

 by about their diameter on upper half, becoming sparse or very 

 sparse ventrally, separated by about 3 to 5 times their diameter 

 near lower edge; hairs on hind femur often unusually long; second 

 segment of middle tarsus about 2.8 as long as deep; fifth segment of 

 hind tarsus about 1.4 as long as second segment; second tergite 

 smooth, polished except for a little fine wrinkling and weak micro- 

 reticulations basally, its punctures fine, sparse, but evenly distributed, 

 separated from each other by about the length of the hairs.
