Genus Argas 



N.B. These points are taken from Neumann's description of 

 A. kochi, based on a single £ from Basutoland, collected by Cristol 

 (Paris Museum). White's description is insufficient, but Neumann 

 found the types (2 females) in the British Museum and they agreed 

 with A. kochi, except in the genital orifice (a sexual character) and the 

 fact that the tarsal protuberance was almost as well marked on tarsi 

 2, 3 and 4 as on tarsus I. If the examination of other specimens of 

 A. transgariepinus should show similar tarsi in both sexes, Neumann's 

 species would become A. transgariepinus var. kochi. (There are 

 3 females (dry specimens) in the British Museum collection. The 

 accompanying figure was drawn from one of these measuring 10 x 7 mm., 

 a smaller specimen measured 8"5 x 6 mm.)

Adults and Nymphs : Body flat, only a few nymphs and males 

 showing the dorsum convex through repletion. The adult ? (Figs. 38-41) 

 attains 20 x 13 mm., average size 15 x 10 mm., nymph or young £ 

 measure 7x5 mm. Sides of the body parallel, its anterior border 

 conical, recalling Ornithodoros; posterior border broadly rounded; margin 

 (Fig. 47) finely striate. Dorsum pitted by symmetrically arranged 

 polygonal depressed areas, bounded by rugose ridges, and containing
