insects are very abundant in this region) would not be as likely 
to climb up the clay tube. Perhaps again, O. annulatus con- 
structing fewer cells than its near relative, it would be im- 
perative that these should be better protected. 
Odynerus foraminatus Sauss. 
Oberlin, Decatur County, July 19, 1910. 
Several of these Eumenids were dug out of the same stump 
as Crabro interruptus, previously referred to. The cells of 
foraminatus were larger than those of Crabro and separated by 
partitions of mud, instead of wood chips as in the case of the 
latter insect. The biood was apparently just emerging, but 
what their burrows had been provisioned with was not ascer- 
tained. 
Family VESPIDAE 
Polistes variatus Cresson, Trans. Am. Ent. Soc. IV, 247, 1872. 
A number of specimens of this wasp were taken near Atwood, 
Rawlins County, in July. Trees and houses being rather scarce 
in Northwestern Kansas, the nests of these insects can be found 
suspended in the tunnels of rodents, exposed by erosion, in the 
face of cliffs. Such a nest was found five or six inches inside 
a shallow pocket in a bank. The five adults pertaining to this 
nest were taken. The comb consisted of thirteen capped and 
a large number of open cells, the latter surrounding the for- 
mer. 
The genus Polistes is well represented in Kansas by at least 
eight species ; these are commoner, however, in the eastern half 
of the state. During the late fall females are often found in- 
doors in their instinctive efforts to secure a comfortable place 
for hibernation.

Halictus occidentalis Cress. 
Rarely met with. We dug out a tunnel of this species from 
a clay bank in Wallace County. The hole went straight down 
for 14 inches and ended in three pockets filled with pollen.
