Certain variations in material at hand suggest the need for 

 more specimens from various parts of Africa for further morpho- 

 logical study. 



Females ; Engorged specimens measure from 6.0 mm. to 6.5 mm. 

 long, and from 4.0 mm. to 4.5 mm. wide; tmengorged, they are about 

 2.5 ram. long and 1.5 mm. wide. The scutal length equals or only 

 slightly exceeds the width (0.8 mm. to 0.9 mm. long, 0.7 mm, to 

 0.9 mm. wide); the posterior margin is broadly rounded; cervical 

 grooves are long, deep, and converging; punctations are small and 

 inconspicuous. Palpal features are most distinctive (Figures 130 

 and 131). There is no dorsal projection on palpal segment 3. 

 Coxae I to IV each have a small posterior spur and, in addition, 

 coxa I has a small outer posterior spur; the spur of IV is short 

 and wide thus differing greatly from that of the male. Palpal 

 and scutal characters easily separate females from all other 

 African species. 



The larva and nymph have been described and illustrated by 

 Theiler (T^^).
