ing this species to Colonel Bingham in acknowledgment of his 
kindness in redescribing and figuring Smith’s types. 
“1, Differs from the female (P. affinis which Smith regarded as the female of this 
bee.—J. H. L.) conspicuously in color of the abdomen, which is exactly the color 
of a peeled horse-chestnut, in the more slender shape of the body and in the head 
and thorax being clothed somewhat thickly with short, erect, whitish hairs. The 
more minute differences in color and sculpture are as follows: Clypeus and the 
raised triangular area above it, the tibize of the fore- and the tarsi of all the legs, 
yellow; the pronotum without the yellow transverse line above. Head slightly 
wider than the thorax not so long as in the female; antenne proportionately longer, 
the basal joints of the flagellum not markedly moniliform. Thorax: the mesono- 
tum without the impressed lines, the triangular space at base of the median segment 
very closely and coarsely punctured, not longitudinally rugose as in the female. 
Abdomen: basal segment with more minute and scattered punctures and on its 
basal half somewhat thickly covered with erect hairs. Length 6 mm.; expanse 
10 mm.” 
For the two excellent figures of Smith’s types illustrating this 
paper I am indebted to Colonel Bingham. Fig. 1. represents the 
female of P. affinis, and Fig. 2 the form wrongly supposed by Smith 
to be the male of this species, to which I have given the name P. 
binghami.

This species occurs throughout the northeastern states, and 
I have before me specimens of both sexes taken at Falls Church, 
Va., by Dr. Nathan Banks. I am not aware that it has ever been 
reported from Colorado, New Mexico, or the extreme southern 
states. It is not a common species in this locality. The female 
has been collected on the garden blackberry, June 24-25; Soli- 
dago, August 9-20; male on the garden blackberry, June 24; 
and Solidago, August 9-21. This species has been repeatedly 
identified as P. affinis Sm., but as has already been shown the two 
forms not improbably occupy different areas.
