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 cacruleum storing 

 its nest with the cricket Gryllns abbrcriatus. 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 bruncri (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 mcigcnii; 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.
