holes were evidently the work of Coleopterous larvae, a spe- 
cies of which was taken. 
A number of these holes were occupied by the Crabro, sev- 
eral adults of which were dug out. The stump was quite soft 
and it is possible that Crabro utilized the galleries of other in- 
sects, modifying them according to its needs. 
The nests (Pl. XIV, fig. 4) had their several cells separated 
from one another by partitions of wood dust. Each of the 
occupied cells had been provided with moths, almost all of the 
species L. sticticalis (for moth see Pl. XVI, fig. 7), perhaps 
also with L. commixtalis Walker, which were not as abundant 
as the former, and one or two other small species of moths. 
No larvae of Crabro were found, but several unopened co- 
coons examined later contained dead adult wasps. The brown, 
paper-like cocoon itself was enveloped and hidden by the moth 
wings arranged in a more or less shingled manner and other 
portions of the consumed moths. The base of the wings of 
the moth always faced the distal end of the cell, showing that 
Crabro always brought its prey in head first. 
Early in 1911, several of the Crabro cocoons were opened 
and two revealed a Hymenopterous larva, evidently one of the 
Parasitica. 
It may be of interest to know that Lorostege sticticalis and 
commixtalis, occur in Europe as well as in America, and may 
be therefore an importation from the Old World. These two 
moths, particularly the first mentioned, are abundant in North- 
western Kansas and undoubtedly have a wide range in the 
United States. The larva is considered an alfalfa pest by the 
farmers, and was found to be very abundant on the obnoxious 
Russian thistle (Salsoka kali), and in Wichita County were 
observed moving in armies of considerable magnitude. 
The Peckhams in their book “Wasps, Solitary and Social,” 
report a Crabro sp? as provisioning its nest with white moths 
which it packs lengthwise of the cell. They found four species 
of moths in the nests opened.
