Falls Church, Va., Aug. 7, type (Banks). Herndon, Va., 

 August (McAtee). Argo and Edgebrook, 111., Aug. 13 — 17 

 (Gerhard) ; one of the two specimens from a branch of dead 

 hickory. Ranges from Ontario and New England southwest 

 to Georgia and Texas and west to Iowa and Kansas. One of 

 our most widely distributed species of Empicoris, but the synon- 

 ymy is so confused that the true range is problematical.
