The Sphegoidea of Nebraska 37 
Both sexes were taken at Glen, during the expedition of 1906 
(P. R. Jones, H. S. Smith). Very distinct by the red basal ab- 
dominal segments. ;

One male, Lincoln, July (H. S. Smith) ; one male, West Point, 
June 28 (P. R. Jones). A beautiful species, recognizable by the 
strongly convergent eyes and black pubescence of male. 
Philanthus gloriosus Cresson.

Two females, Lincoln and West Point, June 25 (P. R. Jones). 
The yellow bands described by Cresson as occurring on the ven- 
tral segments are wanting in these specimens. I have also three 
males, West Point and Glen, August (H. S. Smith) ; this sex is 
heretofore undescribed so far as is known to me. The abdomen 
is considerably more slender than that of the female, front more 
prominent, the yellow mark between and above the bases of the 
antennae extends up higher and the tibiae and tarsi are yellow. 
The femora are either red or black; the antennae are not reddish 
beneath. The specimen with the red femora has two ferruginous 
spots on the first dorsal segment of the abdomen. The pubescence 
varies from gray to brown.
