This species is represented by a single specimen and its reverse in 

 wliicli the wings and an obscure and detached fragment of the abdomen are 

 present. The wing appears to be devoid of markings. The auxiUary vein 

 does not fairly impinge upon the first longitudinal vein, but bends toward it 

 and then vanishes ; in other respects the neuration of the base of the wing 

 is precisely as figured by Winnertz for Brachypeza ; so, too, are the origin, 

 course, and position of all the principal veins and the cross-vein, but the 

 branches of the fifth longitudinal vein unite perhaps a little farther from the 

 base, viz : scarcely nearer the base than the point of separation of the united 

 third and fourth longitudinal veins from the second ; the sixth longitudinal 

 vein is perfectly straight, and terminates quite as far from the base of the 

 wing as the small transverse vein ; the anal vein is regularly curved, about 

 as long as the sixth longitudinal vein, runs parallel to the border beside it, 

 and terminates on the lower margin. 



Length of wing, 4"'° ; breadth of same, 1.35'"'°.

Brachypeza procera.

Brachypeza procera Scndd., Rep. Progr. Geol. Surv. Can., 1875-1876, 272 (1877). 



The single specimen of this species is in a very fair state of preservation, 

 almost the entire neuration of the wings being preserved, as well as frag- 

 ments of the body and other appendages. The wings are fuliginous, more 

 deeply next the costal border. The neuration of the extreme base is lost, 

 and the remainder difi"ers from that of B. abita only in the lower half of 

 the wing ; the branches of the fifth longitudinal vein unite nearer the base 

 than in that species, resembling, in this respect, the illustration of Brachypeza 

 given by Winnertz ; the lower branch curves strongly toward the tip, diverg- 

 ing unusually from the upper branch ; the sixth longitudinal vein is straight,
