NOTES ON NEBRASKA BEMBICIN.t. 



BY CLARENCE E. MICKEL, LINCOLN, NEBRASKA. 



Recently the writer worked over the material of the sub- 

 family Bembicina? in the entomological collection of the Uni- 

 versity of Nebraska. In \\e\y of the fact that there seems to be 

 very little Nebraska material of this sub-family in other entomo- 

 logical collections and since a monograph of the Bembicinae has 

 lately appeared, the time seems opportune to publish a list of the 

 Nebraska species. Some notes on synonym>' are also included.
