from yellowish brown to pitchy-black. The abdomen is 

 dull black or piceous, with short grey hairs ; the sides 

 and base are usually paler, and sometimes yellowish 

 brown. The wings are narrower and more pointed at 

 the apex than in H. struthionis, with the nervures finer, 

 and there are three distinct nervures crossing the wing 

 obliquely to the hind margin. The legs vary in colour 

 from piceous-brown to pale brownish yellow ; the claws 

 are black, and differ from those of Hippobosca in being 

 acutely bidentate from the base ; the inner tooth is as 

 fine and nearly as long as the outer one ; the feet thus 

 appear to have four ungues, or claws, on each. The head, 

 thorax, apex of the abdomen and the femora have, 

 besides the pubescence, some long brown bristles or 

 setae. The expanse of the wings is 13 15 millm.

The specimens sent over of the fly described and 

 figured above were taken from tame pigeons by Mr. J. 

 Crawford, of Port Elizabeth, and similar flies are said 

 to be found on wild birds. These being (like the Ostrich 

 Flies mentioned previously) of the family of the Hippo- 

 boscida, they have the same method of increase, and 

 similar principles of treatment would be applicable to 

 keeping down great amount of infestation. E. A. 0.
