larva. Polistes and Diptera were chased from the coveted 
spot, the Chlorion making short threatening rushes at what it 
considered intruders. Ants were not in favor either, but were 
driven away with a show of unwillingness on the part of the 
wasp, which made gingerly digs at them with its mandibles 
until the desired object was obtained. 
The Peckhams* have observed Chlorion caeruleum storing 
its nest with the cricket Gryllus abbreviatus. At Tribune, 
Greeley County, Kansas, August 17, 1910, we observed a fe- 
male of this species running up a clay bank, carrying a mature 
female Ceutophilus near bruneri (Locustidae). The wasp was 
evidently striving to reach a sufficient altitude to fly to its nest 
with its somewhat heavy burden. 
The habits, therefore, of Chlorion seem to vary somewhat 
as regards the provisions used, and though the latter with this 
species are probably always an Orthopterous insect, the spe- 
cies must to some extent be determined by the abundance or 
scarcity of certain Orthoptera. 
No tunnels of Chlorion were dug out; the Peckhams, how- 
ever, figure one in their book on Solitary Wasps; it is large, 
trending obliquely and terminates in a pocket. 
Family BEMBECIDAE 
Bembex sayi Cress. 
Atwood, Rawlins County, Kansas, July 19, 1910. 
A burrow of this species which was dug out of a sandy 
slope was about eighteen inches in length, sloped slightly 
downward and terminated in a chamber, which contained a 
quarter grown Bembex larva abundantly supplied with dead 
flies, among which were three Tachinids (Archytas analis 
Fabr.), a Stratiomyid allied to appiculata and meigeni; a 
Tabanid of the genus Chrysops, one Musca domestica, two 
flesh flies and the remains of several other flies. 
A species of Bembex found in Wichita County was taken 
from a burrow at the depth of two and a half feet.
