18 ROBERT NEWSTEAD— A REVISION OF THE TSETSE-PLIES (uLOSSINA), 



Legs yellowish brown or buff ; femora broadly and distinctly infuscated, especially 

 the middle and hind pair. Middle and hind tibiae also with a very broad 

 infuscated blotch ; anterior tarsi with the tip of the fourth segment black, last 

 segment dark at tip but not black ; middle tarsi similar ; hind tarsi all dark, but 

 the distal half of the third segment and the whole of the two succeeding ones 

 black ; hairs on ventral surface bright golden brown. 



Female. Differing from the male in having the legs decidedly paler ; the 

 hind tai'si with the last two segments black, the second and third with the tips 

 only black. The thoracic and abdominal markings and also the form and 

 strongly pubescent character of the long terminal segment of the antennae are 

 specifically the same as in the male. 



Described from four examples, three males and one female. One male was 

 taken at Kasongo, Congo Free State, 6. II. 04 {Drs. Ihitton and Todd); 

 another at Suuyani, Ashanti, 5. III. 10, and the third at Atroni, W. Ashanti, 

 16. VIII. 10 {Dr. A. Kinghorn) ; the only female I have yet seen was taken 

 at Odumase, W. Ashanti, 27. IV. 10 {Dr. A. King horn). 



Genital Armature of the male (fig. 5). Superior claspers (.se), free and 

 strongly bidentate ; bristles long and slender ; proximal half of the dorsal 

 surface clothed with finely-pubescent hairs. The editum or extension of the

body-wall (/) with relatively few bristles, the longest reaching to the base of the 

 harpes ; some of the bristles are broken or entirely wanting, and it is highly 

 probable that some of these may prove to be longer than those shown in the 

 illustration. Inferior claspers («•), clothed with numerous long hairs ; distal 

 margin presenting an ogee curve, the base being strongly and broadly produced, 

 the distal angle narrowly produced and narrowly roimded ; proximal margin with 

 a very deep and somewhat elliptical emargination. Median process {mjj)
