Identification | |
Extracted from: Fowler, C. (1899). California Bees of the Genus Nomada. Academy of Natural Sciences, Philadelphia Vol. 10 no. 6.
Female. Differs from the male in that the pubescence on the face
is much shorter ; the third joint of the antennae is about one-half the length of the fourth.
In all of my specimens the first segment of the abdomen is black at the extreme base, both above and beneath, the two
black spots mentioned by Cresson sometimes fusing with this. Sometimes there is a little black on the apical margins of
segments 2—4
