226 Genus Ixodes 



he was mistaken in the length of the <£ I. pilosus, which averages 

 2"8 mm. (and not 3"15 mm. as given in his description), so that the 

 varietal differences almost disappear. The only specimen he was able 

 to send us of /. pilosus var. howardi was a microscopic preparation of 

 the ? , which appears to us identical with the specimens of /. pilosus 

 from Lounsbury's collection. His description of the variety is as follows : 



Ixodes pilosus var. howardi Nn. 1908. 



Lit. : Neumann, 17. VI. 1908, p. 125. 



Howard, C. W., 17. VI. 1908, p. 126 ; also vin. 1908, p. 95, PI. IV, Figs, a-k ; 

 describes (J , ? , larvae, eggs ; figures <J and $ and details thereof somewhat 

 sketchily. 



Male: resembles the type, but is smaller, 2-.3xl - 2 mm. (type measures 

 3*15 x 1*6 mm.; average length 2"8 mm., see top of this page). 



Female : differs from the type as follows : Scutum longer than broad 

 (1*27 x 1*1 mm.), oval; cervical and lateral grooves less marked; punctations 

 finer, less deep, more numerous ; hairs less numerous on dorsum and venter. 

 Anal grooves with branches closer together and forming an open ellipse posteriorly. 

 Capitulum smaller, 0'7 mm. (instead of - 85 in type ; porose areas smaller, shallower, 

 wider apart. Legs much feebler, especially the coxae. General colour, unfed, orange- 

 red. 



Description based on 2 $ s and 12 9 s, found on dogs at Leydsdorp, Transvaal, by 

 Dr Copland and at Durban, Natal, by Dr Theiler, and sent to Neumann by C. W. 

 Howard (Pretoria). The latter subsequently took specimens in various parts of the 

 Transvaal, i.e. in the Marico, Rustenburg, Pretoria, Barberton and Zoutspansberg 

 Districts, and at Piet Retief and Durban in more or less dry or very arid places. 

 Howard states that "most of the localities are in the low bush veldt, but those 

 places on the high veldt (about 4000 feet) where the tick is common, are those 

 parts which are covered with bush, and the tick is apparently lacking in the high 

 grass." 



The principal host is the dog, but Howard has found specimens on a cat, 

 Erinaceus frontalis and Rhinolophus sp.
