with short black hair. In fore wings the first apical sector arises 

 before the middle of discal cell, the latter scarcely as long as its pedicel 

 and narrowed at tip; the radius downcurved and then upcurved 

 before the pterostigma ; arculus nearly straight, not angulate at end of 

 cubitus, but the branch from median is angulate to meet the arculus. 

 In hind wings there is a cross-vein from discal cell to radius, and the 

 first sector arises from the middle of this cross-vein; the discal cell 

 is very short, the third apical cell narrowed at base. The tibiae of 

 legs have only a few short black spines; those on the hind tibiae not 

 more than one-half the diameter of the joint. 

 Expanse, 38 mm. 



One specimen from St. Anthony Park, Minn. (Pettit). 



Neuronia canadensis, n. sp. 



Head black; face with erect golden hair; posterior warts rufous, 

 bearing rufous hair ; palpi pale ; antennae reddish brown ; lobes of pro- 

 thorax yellowish, and with long yellowish hair; thorax black, lateral 

 lobes pale, and the scutellum rufous, with golden hair; legs yellowish, 

 with golden hair and black spines, femora blackish on bases ; abdomen 

 black. Wings yellowish, fore pair densely irrorate with brown, a larger 

 spot before and after pterostigma, and at ends of veins, and at arculus ; 

 venation brown; membrane finely granulate, and with sparse golden hair. 

 Hind wings yellowish hyaline, a brown spot before pterostigma, and 

 beyond a few brown irrorations, and dark at ends of veins. Fore 

 wings broad, broadly rounded at tip ; discal cell about three-fourths as 

 long as pedicel ; first apical cell as long on discal as width of latter, 

 fifth not extending back as far; the arculus angulate; cross-vein from 

 median to cubitus ends beyond forking of latter vein. 



Expanse, 28 mm. 



One specimen from Guelph, Ontario, Canada (Jones). Dif 

 fers from nearly all others by fork i arising beyond middle of 

 discal cell ; from stygipes and pafdalis by pale hind wings ; from 

 lapponica and dossuaria by broader, more densely irrorate 

 wings, and curved arculus.
