(3) R. evertsi, Neumann, 1897. Characterized by its dark brown scutum, bead- 

 like eyes and reddish yellow legs (fig. 22). It is commonly known as the 

 red-legged tick in South Africa. For biology see p. 345. 



R. evertsivsiT.albigemculatus, Warburton, 1915 (n. var.), received by us from 

 the Lower Congo, only differs from the above in having banded legs. On 

 superficial examination it might easily be confounded with Hyahmma 

 aegyptium.

(original, L. E. Robinson). 



(4) R. falcatus, Neumann, 1908. Scutum very coarsely punctate ; sickle-like 



adanal shields (fig. 23). 



(5) R. lunulatus, Neumann, 1907. Adanal shields with two points (bifid) at the 



posterior margin (fig. 24). Otherwise the species resembles R. simus (no. 7).
