The two new species of fleas described in this paper are of unusual interest. The first belongs to the well-known genus Catallagia Rothschild (Hystrichopsyllidae: Neopsyllinae), but is notable for the extreme modification of the male genitalia, a condition not reflected in the female; the second, a bird flea, belongs to Ornithophaga Mikulin (Leptopsyllidae: Amphipsyllinae), a remarkable genus recently described from the U.S.S.R. on the basis of one female specimen.
