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.
