Genus Haemapln/ sails 



with its posterior border almost straight dorsally, but with a ventral 

 retrograde spur directed outward ; lateral contour of articles 2 and 3 

 continuous and concave outwardly ; article 2 twice as long as article 3 ; 

 hypostome 2 2. Legs with a sharp internal spur on all the coxae. 



Through the courtesy of Professor Neumann we have been able 

 to study and figure one of his type specimens ((/ ), the species having 

 been founded by him on 5 </ and 1 o from Spermosciurus sp., Sichi Baz, 

 Abyssinia, collected by Hilgert (received in 1901 from Erlanger).

 with coxae and trochanters, spiracle and tarsus IV. (N. 1224.) Original, N. C. del. 



Neumann, 1910, p. 173, records 2 cT and 8 $ from a squirrel, 

 Ros^res, Upper Blue Nile, Egyptian Soudan, 1906, coll. C. Alluaud 

 (Paris Mus.). The female as described and figured by Neumann (1910) 

 does not agree so closely with the male as do our specimens ; we do not, 

 therefore, reproduce his figures. 



Our description of the adults and nymph is based on specimens 

 (N. 1203, 1224), 4 ci" 2 $ and 1 o, from Xerus rutilus, Biacobaba, 

 Somaliland, iv. 1901, presented by Dr E. Brumpt, and the study 

 of a type (/.

Haemaphysalis calcarata var. houyi 

 Nuttall and Warburton, 1915, n. var. 



Male : Resembles the typo but foi- its somewhat sturdier build and 

 the fact that the trochantal spurs arc short and blunt, the palps being 

 somewhat shorter and more massive.
