This color is darker in the costal cells, especially in the interval between the 

 auxiliary and the first veins; costa distinctly incrassate in the region of the 

 stigma ; veins brown. 



"Hab. — White Mountains, New Hampshire. Two specimens. 



"Easily distinguished from the other described species of the genus by its 

 strongly infuscated wings and its large size. The abdomens of my specimens 

 being somewhat shrunken, the measurement I give is only an approximation." 



There are nine specimens of this species in the United States 

 National Museum. The pile of the body is veiy pale yellow, in 

 some forms whitish. In all the abdomen is somewhat shriveled 

 as in the type material. A specimen from San Diego, Texas, 

 October 26, is 8.5 millimeters in length. A specimen from 

 Camel's Hump, Vermont, has very narrow, white, posterior 

 margins on third, fourth and fifth segments of abdomen and no 

 distinct markings on the venter. The legs are uniformly pale 

 brown. A specimen from Tyngsboro, jVIassachusetts, has the 

 underside of the femora and tibiae yellow. One typical specimen 

 from Victoria, Texas, April 5, was collected by E. A. Schwarz. 

 We have also a specimen collected at St. John, New Brunswick, 

 July 8, 1902 (W. Mcintosh), and one specimen from the type 

 locality (Morrison). I have seen specimens from New York, 

 Maine, Massachusetts and Illinois. The specimen collected by 

 Morrison has yellowish legs, yellowish antennae and brown hu- 

 meri. The wings are infuscated but pale. A rather small speci- 

 men from Rociada, New Mexico (Cockerell), has pale wings and 

 legs. A specimen received from Nathan Banks was collected at 

 Falls Church, Virginia, August 21.
