Bishopp — A New Species of Drrmacentor . 31 



between macula and marginal cells; macula nearly circular, slightly ele- 

 vated. 



Body (Fig. 10) elongate-oval, marginal strip yellowish brown, punctate 

 and bearing numerous long pale hairs; venter, pregenital plate nearly 

 rectangular with rather large punctures; median plate fully twice as long 

 as broad, sparsely covered with small punctures and long yellowish hairs; 

 anal plate in form of truncate cone, height but little greater than width 

 of base, sides slightly convex, with a few small punctures; adanal plate 

 longer than width along median plate, which is greater than width along 

 posterior margin, bearing a very few shallow punctures and long hairs; 

 lateral plates sparsely punctate, punctures medad of stigmal plates very 

 large; scattered large punctures between coxae and ventral plates. 



As the original description of this species by Prof. Neumann and the 

 description by Mr. Banks were based upon but tw r o females, and these 

 mutilated, a few additional descriptive notes on the female are here 

 presented. The species is easily identified, however, by either of the 

 above mentioned descriptions. 



Female. — Capitulum (Figs. 9, 12): length from 717 to 731m (from tip 

 on hypostome to a line drawn between tip of postero-lateral angles) ; basis 

 capituli 410 to 438/* wide, smooth dorsally; ventrally, with two stout 

 sharp spines, 04 to 86m in length, curved ventro-posteriorly ; porose areas 

 shallow and quite uniform in shape in all specimens; palpi 507 to 003m in 

 length; hypostome long, moderately stout and fairly acute at apex; two 

 tiles of teeth on basal half, three files apically and four files near tip. 



Scutum from 1 mm. long by .947 mm. wide to 1.2 mm. long by .938 

 mm. wide, dark reddish brown in unfed specimens, almost black in some 

 fed individuals ; the punctures are quite similar in all specimens, very 

 small and sometimes almost absent anteriorly, rather large and more 

 numerous toward tip; with long, yellowish, scattered hairs ; lateral cari- 

 nae distinct but rounded, running to margin of scutum at its posterior 

 fourth ; cervical grooves distinct, first converging, then diverging widely 

 and disappearing near lateral carinae behind the middle of the scutum. 



Legs very dark reddish brown, lighter in unfed specimens; a consider- 

 able number of long pale hairs on legs and coxae; length of tarsi I 500 to 

 •")74m; length of metatarsi I 287 to 330/*. 



Stigmal plates small (not large as stated by others), from 237 x 172m to 

 215 x 172m; transversely oval; 74 to 87 goblets, of medium size, to each 

 plate, set close together; four rows of goblets at widest and one row at 

 narrowest point between macula and marginal cells ; macula near the 

 center of plate dorso-ventrally but much nearer the anterior than the 

 posterior side. 



Body, margin on dorsum more hairy than scutum and lighter colored; 

 a considerable number of long pale hairs on venter. 



The single unfed female in hand measures 1.74 mm. long (from scapu- 

 lar angles to posterior tip of body) by 1.21 mm. wide. The partially 

 engorged females are elongate and are much darker in color than the 

 unfed one.
