Genus Ixodes 



Fig. 219. I. pilosus ? : oapitulum in ventral and dorsal aspects. From the same ? as in 

 Fig. 218. (Original, G. H. F. N. del.) 



Nymph (Fig. 220): resembles the $, especially in the horseshoe- 

 shaped anal groove and a slight external concavity of the palps. The 

 scutum is somewhat more angular, and the coxae have a fairly distinct 

 external spur. 



Fig. 220. I. pilosus o (unfed) : dorsum, part of venter, tarsus 4, spiracle. Specimen 

 from Cape Colony, sent by C. P. Lounsbury, 1906. (N. 921. Original, G. H. F. N. del.) 



Larva (Fig. 221): the palps are slightly concave externally. The 

 anal groove is generally obsolete, but when visible it conforms in shape 

 to that of the $ and o.
