Family III. Cecidomyidae. The Gall-gnats havea long slender body, and short, but comparativelybroad wings, with but few nervures.

Cccidomyia destructor, the Hessian Fly, wasthus named in America, because it was supposed tohave been introduced into America during the Warof Indepcndance by the Hessian troops.
