Cresson described this from nine males collected in Colorado. It is very variable, both in size and markings. At Troublesome, Colorado, alt. 7345 ft., June 9th, 1908, l\fr. S. A. Rohwer took both sexes. The female runs in my table of Rocky :Mountain Nomada (Bull. 94, Colo. Expel'. Sta.) to N. agynia, male, but is quite distinct from that species. As is usual in the group to which the species belongs, the female N. civilis is very unlike the mala, agreeing, however, in the very broad face, with the orbits diverging above. The following characters of the female are distinctive :
Lower part of face, including labrum and supraclypeal mark, lemon-yellow; orbital margins above middle of face broadly ferruginous, this continuing over to the cheek, on the lower half or more of which it gives way to yellow; scape ordinary, yellow in front, antennm otherwise wholly ferruginous, without black or dusky; mesothorax rough, black, with a little red at extreme sides; tegulae light ferruginous, with a yellow spot in front; tubercles and upper margin of prothorax yellow; pleura ferruginous, with a suffused yellow patch; scutellum and postscutellum yellow, with reddish hair; metathorax black, with a pair of large round light red spots, varying to slightly yellowish in the middle; legs clear ferruginous red, the apices of the femora and anterior and middle tibim conspicuously marked with yellow; abdomen bright lemon-yellow, with clear ferruginous bands above and below; on the first segment the yellow is reduced to a mark (one-third of a band) on each side, and there is a black subbasal median spot; on the second segment theyellow is much narrowed in the middle.

Female. Length about 11 mm.; similar to the Corvallis, Oregon, form of
civilis, but differing as follows: Scape wholly light red; tegule reddish (instead of yellow); mark on pleura suffused with red, and reduced, its posterior .lobe obsolete or almost; yellow on scutellum reduced, with a median black line; metathoracic marks reddish, very
small; yellow of legs mainly replaced by red; apical half of first
abdominal segment red, with a small obscure yellowish spot on each
extreme side; second and third segments very broadly red in the
middle. The nervures and stigma are bright ferruginous, and the
second submarginal cell has the characteristic broad form, with the
r. n. joining it beyond the middle. (The venation indicates its relationship with N. civilis, and distinctness from the rather similar 2V.
