Two Introduced Field Crickets New to Eastern United States (Orthoptera: Gryllidae)

Abstract
The Jamaican field cricket Gryllus assimilis (Fabricius), widely distributed in the West Indies and in South and Central American countries bordering the Caribbean, appears to be established in south Florida. A Japanese burrowing cricket, Scapsipedus micado Saussure, was found in Huntsville, Alabama, in August 1959. Distinguishing characters and song descriptions are given for both species. Their manner and time of introduction are not known: assimilis has been abundant from the Miami area south since 1958, but live pinned specimens dated 1941, 1954, and 1956 have beer seen. The Gryllinae of the eastern United States are listed, common names are suggested, and the probable effect of shipping various kinds of crickets for bait purposes is discussed.
