inland on sandy areas. Its northern limit, so far as known, is the coast of 

 Conn. It provisions its nest with a variety of dead insects, which it gathers 

 up on the sand. 



SUBFAMILY OXYBELINAE 



(Crabroninae) 



Tribe SOLENIINI 



(Crabronini) 



Some species of this tribe nest in the ground, some excavate the pith of plants, 

 some build in solid .wood, and some use deserted burrows or any suitable hole. Mostly 

 the nests are provisioned with flies. The genera and subgenera recognized in this 

 tribe correspond to those recognized by Kohl in his recent monograph of the Pale- 

 arctic forms. The "Artengruppen" of Crabro are here recognized as subgenera, but 

 his "Untergruppen" are not so recognized.
