Nomada crawfordi lachrymosa
WYOMING: 1 <.;? (type): Jackson, about 6300 ft. alt., along Cache Creek, among vegetation of moderately moist pasture-land type, July 15,1920; 1 <.;?, Rawlins, about 6800 ft. alt., among sagebrush on a hill near town, June 2.), 1920; 1 <.;?, Medicine Bow, about 6600 ft. alt., among sagebrush on the ridges having a few Pinus scopulorum, June 23, 1920. <.;? .-Length about 11 mm.; general color of head, thorax and legs bright ferruginous, of abdomen bright yellow; eyes pale reddish gray; mandibles simple, black at end; labrum yellow; lower border of clypeus and sides of face sufTusedly yellow; face broad; cheeks with pale red hair; front red; antennre entirely brightferruginous or darkened apically, third joint long, b.ut shorter than fourth; mesothorax dull and densely punctured, dull red, with a black mark posteriorly; tubercles and upper border of pro thorax yellow; pleura red, with a small yellow mark, not always present; scutellum strongly bigibbous, it and the postscutellum red; metathorax with a pair of dull pale yellow spots, and often a black shade in center of basal area; tegulm orange, with a yellow spot; wings reddish, stigma bright ferruginous, nervures fuscous; basal nervure going a little basad of transverse median; anterior tibire faintly suffused with yellow at base; hind femora with a broad black area behind; hind tibire with an apical outwardly projecting emarginate lobe; hind basi tarsi with shining golden hair on inner side; abdomen yellow with four narrow red bands, first segment red at base; venter yellow with bases of segments red, and first segment all red; second segment broadly emarginate posteriorly. A Xanthidium, running in the tables near to zebrata and rufula, but quite distinct. It closely-resembles N. crawfordi Cockerell, differing by the broad continuous yellow band on first abdominal segment, whereby it resembles 1"1. rhodoxantha Cockerell. The proportions of the antennal joints are as in crawfordi, and after close comparisons I must regard it as a race or variety of that species, rather than an independent species. Swenk refers to a form of crawfordi from Nebraska, with a complete yellow band on first abdominal segment. Swenk suggests that the males which I described as N. gillettei and N. ednce represent variations of crawfordi. I have no gillettei but, on comparing the type of edn~, it seems to me to be specifically distinct, though very closely allied. The name of this variety is in allusion to the tear-like yellowish suffusion on anterior orbits.
