plate rising very sharply from the petiole, sometimes at a right angle 

 or even less. 



Wings: Quite uniformly fuliginous with violet to purple reflection; 

 larger veins dark; smaller ones light brown; tegulae black, sometimes 

 rather piceous, particularly on the margin ; shining. 



Legs : Rather stout, with scattered, coarse punctures and hairs on 

 coxae, trochanters, femora and near the base of the tibiae; tibiae and 

 tarsi weakly whitish sericeous; tibial and tarsal spines stout; pulvilli 

 absent or very small; claws pale. 



Male. — I have seen but one male which I consider as certainly this 

 species. Possibilities as to the male are discussed below. 



Very small: Ciypeus quite elongate downward, its front margin 

 evenly rounded on its outer third, the central third transverse, even 

 slightly emarginate; surface of ciypeus and of frons (particularly^at

the sides of the latter) silvery pubescent well up toward the ocelli: 

 body rugosities fine (probably because of the small size of the speci- 

 men) ; petiole about three-fourths as long as the hind coxa and trochan- 

 ter together; wings less strongly fuliginous than in the female; legs 

 almost piceous, rather than black; pulvilli large. No trace of ferru- 

 ginous anywhere. 



Length. — Female, 12-20 mm. (one pigmy of 10 mm.); male, 9 

 mm. (only one seen). Over 350 specimens examined. 



Distribution. — Found practically everywhere in the Northern 

 United States and the Southern Canadian territory. I have seen 

 specimens from Nova Scotia and every Province of Canada west to 

 Vancouver; and in the United States from Maine, New Hampshire, 

 Vermont, Massachusetts, Michigan, Wisconsin, Minnesota North 

 Dakota, Montana, Idaho, Washington, Oregon, and California south
