H. parmata 421 



This species is closely allied to H. hystricis Supino. 



Our description is based especially upon the examination of (N. 1899) 

 adults from Sierra Leone and of co-types (N. 2887, 2888 cf $) from 

 Cameroon ; the immature stages (N. 2354), now first described, came 

 from the Congo Free State. 



Geographical Distribution and Hosts. 



We have received or examined and determined the followdng 

 specimens from Africa : 



Uganda : (N. 884 c) 2 ? from bushbuck in. 1909, and (N. 877) 1 ? 

 from cattle which came from Bukedi to Mpumu, Chagwe, ix. 1909, both 

 lots having been sent us by Sir David Bruce. J. H. Ashworth's 

 collection contains 1 % from a bushbuck shot at Toro. British East 

 Africa : (E. 307 6) 1 ? from Jackson's hurtebeeste. Upper Nzoia River, 

 North Kavirondo, collected vi. 1911, by S. A. Neave. Congo Free 

 State : (Liverpool N. 45 a) 1 % from antelope, Kasongo, collected i. 1905, 

 by Drs Button and Todd; (N. 2354). cf Os and larvae from antelope, 

 Kimaka, 15. Vl. 1913, and (N. 2906) a large cT from buffalo, Beni, 31. VI. 

 1913, collected by F. Barker. Gold Coast : (N. 504) 2 c/ 1 $ 2 o, 

 collected in 1908 at Prahsu by Dr W. Graham. Sierra Leone : 

 (E. 584 = N. 1899) cTs $s os from harnessed antelope, Port Lokko, v. 

 1912, and (E. 106 a) a % from Cross River, Obubura, vi. 1912, both 

 collected by Dr J. J. Simpson. J, H. Ashworth's collections contain 1 % 

 from cattle, Securella, 19. ii. 1913, collected by Dr J. Y. Wood. 

 Cameroon : Prof Neumann has presented us with co-types (N. 2887 

 </) from Bos taurus, Njanga, 1904, and (N. 2888 %) from Capra hircus, 

 Mbula, 1904, collected by Dr Ziemann, who also found the adults on 

 sheep and pig in this region. [Ziemann (1905, pp. 116-117), whose 

 specimens were determined by Neumann, records that the tick occurs 

 on cattle at Lagos (Coastal Region), on pigs in Cameroon, on cattle and 

 goats in Duala (Coastal Region), on cattle, goats and pigs in and about 

 the Bakossi Mountains and on cattle in the Cameroon Mountains. 

 Ziemann, i. 1912, p. 58, states that he found specimens on cattle, goats 

 and dogs in the Cameroon Coastal Region. We learn b}' correspondence 

 that he also found the tick on " pigs " i.e. Potamochoerus porcus L., at 

 Akonolinga, 6. vii. 1910 ; he informs us that the latter were determined 

 either by Neumann or Donitz.] 



[Galli-Valerio, 1909, p. 539, states that DrNarbel found H. parmata 

 on a monkey in Sumatra, 1909, but the determination appears to us 

 doubtful, as the species has not hitherto been found outside Africa.] 



The types are in Toulouse, the co-types in Cambridge.
