Chicago, 111., Sept. 6; Mobile, Ala., Dec. 26; Brownsville, 

 Tex., July 24 (Gerhard). Everglade and Chokoloskee, Fla., May 

 12 — Sept. 1 {Davis). Recorded by Barber from four other sta- 

 tions in southern Florida. Outside of that State it has been 

 heretofore recorded in this country only from Kansas, Colo- 

 rado, Texas, Arizona and California, though known from Co- 

 lombia, Mexico and Cuba. The Chicago specimen was taken 

 near the observatory in Washington Park and was perhaps ad- 

 ventive. The Mobile specimens are brachypterous with mem- 

 brane very small.
