veins dark stigma and costa pale; legs testaceous, coxae and tro-

Male. — In structure and color much like female but differing 

 markedly in color as follows: entire face, malar space, lower cheeks, 

 orbits except a very narrow interruption on cheek, mandibles, 

 scape and pedicel beneath, propleura, triangular spots at origins of 

 notauli, spots on pronotum immediately below these, scutellimi 

 laterally, postscutellimi, tegula, spot below, another spot lower on 

 mesopleurum, and an irregular elongate spot before middle coxa 

 yellow; front and middle coxae except at base behind, their trochan- 

 ters, a large spot on upper outerside of hind coxae toward apex and 

 a smaller one on the upper inner side, apical joint of hind trochanter, 

 front and middle legs otherwise except testaceous streak on upper 

 side of femora and blackish apical joint of middle tarsus, basal half 

 or more of hind tibia and its tarsus largely yellow to stramineous; 

 hind femur piceous; first tergite black except a narrow piceous apical 

 margin in which are two small transverse yellow spots; second and 

 fourth tergites red medially black laterally, third entirely red except 

 black spiracular streaks, tergites beyond fourth entirely black. 



Type-locality. — Godbout, Quebec. 



Type.— C&t. No. 27685, U.S.N.M. 



Described from nine females and six males all taken at the type- 

 locahty by E. M. Walker on July 25, 1918. 



The only variations of moment are in the extent of the yellow 

 markings in the male; the yellow spots on postscutellum, first tergite 

 and the inner one on the hind coxae sometimes wanting and the first 

 tergite entirely black. In other specimens these markings as well as 

 the others are larger than in the allotype.
