Female. — Length, 13.5 mm.; wing, 10 mm. Like fraternus from 

 which it differs as follows: Clypeus with lateral angles slightly nearer 

 apex than base, apical emargination more shallow, surface finely 

 punctate; furrow in the propodeum inconspicuous, not extending upward 

 to the metanotum; petiole campanulate, nearly half as wide as long, 

 lateral teeth visible dorsally, no conspicuous contraction before the 

 apical cordon; second segment of the gaster nearly as wide as long with 

 the dorsal angle abrupt, more flattened dorsally and more finely punctate 

 than fraternus. Black; larger part of clypeus, a spot on the tegulse, 

 a spot below the tegulce, the spot on either side of the second segment 

 of the gaster elongated into an oblique line, apical margins of all seg- 

 ments of the gaster 1 to 5, yello wish- white ; ends of tibffi, tarsi and wings 

 brown. Covered with grayish pile of medium length and density. 



Male. — Length, 10 mm.; wing, 8.25 mm. Differs from the female 

 as follows: More slender, clypeus narrower, with lateral angles less 

 prominent than those of fraternus. Clypeus entirely, and the margin 

 of the sixth segment of the gaster and more surface of the legs, yellowish- 

 white. Spots below the tegulas and on the sides of the propodeum 

 absent. 



Distribution. — The range of this species overlaps that of 

 fraternus and extends north of it. Saussure records it from 

 Illinois and Wisconsin in the United States and from Great 

 Slave Lake in Canada. In the National Museum are specimens 

 labeled as follows: Waldoboro, Lincoln Co., Me.; Durham, 

 Strafford Co., N. H.; Mass.; N. J.; Ind. and Mich; in the 

 United States, and Montreal, Province of Quebec, and a number 

 of other specimens simply labeled Canada. 



Type. — Probably in the Museum of Geneva, Switzerland. 



Like verticalis, this species is frequently confused with 

 fraternus. In many respects it is much like both of the above 

 species and also like coloradensis. The clypeus in general 

 shape and in its fine punctation resembles coloradensis rather 

 than fraternus or verticalis. The campanulate petiole resembles 

 that of verticalis and coloradensis, while the prominence of 

 the teeth of the petiole resembles that of coloradensis and is 

 unlike that of the others. It resembles fraternus and differs 

 from the other two by having the second segment of the gaster 

 less distinctly punctate than the petiole, by the shining black 

 color and markings of yellowish-white, instead of bright yellow.
