202 Bishopp — Some New North American Ixodidfe. 



arranged in irregular concentric rows ; five rows between the macula and 

 marginal cells at the widest point and two rows at the narrowest; mar- 

 ginal cells much smaller than goblets, close together and somewhat 

 rectangular; macula oval, slightly elevated above smooth area surround- 

 ing it ; this area is depressed slightly below the goblet covered portion. 



Body pale yellow, punctate, rather densely covered with moderately 

 short pale yellow hairs ; genital aperture opposite coxae III; anal groove 

 broadly round in front of anus and divergent behind it; anal frame about 

 one-half as broad as long. 



Male. — Capitulum (Fig. 11), length 517m (from tip of hypostome to a 

 line connecting postero-lateral angles of basis capituli) ; basis capituli dark 

 brown, greatest width at base of palpi (41(>m) slightly narrowed from this 

 point to posterior angles which are 301 ;"■ from center to center; these 

 angles prominent; on the ventral side of the basis capituli is a nearly 

 semi-circular ridge curving backward from near the base of each palpus 

 where it is very prominent ; palpi very short and broad (length 351 a*, 

 width 194 m); the third segment broader than long, the second nearly as 

 broad as long. 



Scutum, length 2.58 mm., width 1.28 mm., brownish yellow, darker in 

 front over an area corresponding to the shield in the female, sides nearly 

 parallel, broadly rounded behind; surface shiny with a very few short 

 pale hairs, closely covered with large deep punctures at anterior end, 

 these become small and more scattered posteriorly to the middle of the 

 shield where they disappear; the posterior half of the scutum has a few 

 exceedingly minute punctures; lateral carinae strong, running from 

 angles of capitular emargination to edge of scutum one-fifth of its length 

 back ; as in the female, shield is depressed immediately mediad of the 

 lateral carinae ; cervical grooves indistinct, shorter than lateral carinae, 

 only distinctly visible toward their posterior ends. 



Legs (Fig. 12.) moderately short and rather slender, yellowish brown; 

 tarsi III and IV gradually tapering at tip, others rather abruptly nar- 

 rowed ; all coxae with a distinct apical tooth and coxae I with a short 

 stout spine (about 86 /j. long ). 



Stigmal plates Longitudinally oval (287/* x 251 m); 90 goblets per plate, 

 medium sized and rather more scattered than in female; arranged in 

 concentric rows, five rows at the widest and two at the narrowest point 

 between the macula and marginal cells ; a much smaller area is left with- 

 out goblets around the macula than in the female; marginal cells about 

 one-half the size of the goblets and somewhat rectangular; macula oval, 

 situated ventro-anteriorly from center. 



Body (Fig. 12), marginal strip around scutum extends forward to 

 opposite second pair of legs, pale yellow, punctate and with numerous 

 short pale hairs ; venter yellow, plates highly chitinized and without 

 punctures except the lateral ones (which have the stigmal plate located 

 at their anterior end), the punctures on these lateral plates are moder- 

 ately large and close together along their outer halves, the inner halves 

 are free from punctures except a few ventrally from the stigmal plates ; 

 anal groove straight (transverse) in front of anus, the length of this
