Status same as that of Eudoromyia. 
Parexorista cheloxl*: Rond.

1908. Recovered in immediate vicinity of colony site in 1908 and in larger numbers 
in 1909. Not recovered in 1910. Establishment very doubtful on account of hybridi-

PlMPLA IXSTIGATOR Fab. 
First received in 1906 and colonized in 1906 and 1907 unsatisfactorily. Establish-

American species.
