I. ricinus var. scapularis 



157 



Ixodes scapularis Say, in Banks, 1904, p. 144 (occurrence in Florida); 1908, 

 pp. 25, 26, PL IX, Figs. 1, 2 ; PL II, Fig. 15 ( $ unfed, inaccurate ; sexes 

 in copula ( <J attached too far posteriorly), $ venter and capitulum, details 

 fairly accurate (Fig. 15 very sketchy). Hooker, 1908 a, observed copulation. 



Male: (according to Banks, 1908, p. 25) " L. 2 mm. Dark coloured 

 as in female; the palpi are very short, second and third joints no longer 

 than broad ; shield with sub-parallel sides, densely punctate and very 

 hairy ; legs and coxae as in the female ; the stigmal plate large and 

 elongate." 



Female (Fig. 149) : Scutum rather more elongate-oval than in the 

 type, with grooves very faintly marked. Capitulum : base rather 

 narrower than in the type, with more distinct cornua ; porose areas 

 rounder and nearer together ; palps somewhat more pointed anteriorly. 

 Legs : tarsus 4 tapering rather more abruptly. 



Apparently common in the United States (Florida, Texas, Virginia, 

 Iowa, N. Carolina, Maryland, Indiana), where it occurs on man, dog, 

 cattle, and various wild mammals. Neumann's aflinis was found by 

 C. Curtice on Felis pardalis in Costa Rica.
