On the Ethiopian Simuliidae

The object of this paper is to supply a means to the worker in the field for determining the S imuliidae that he may collect, with reasonable accuracy, until such time as he can have them identified by a systematist. A key to the females is given, and Mr. A. W. J. Pomeroy's figures of male genitalia and pupal filaments are reproduced. In this connection the worker is urged not to depend solely on the key to the females, which could no doubt be greatly improved upon when more materialis available, but to make use of the figures of male genitalia and pupal filaments where possible.
