Bishopp — A New Species of Dermacentor. 35 



except on t lie prolongation, aboul II per plate; the supporting cells are 

 rather large around each goblet and around the margin of the plate where 

 they form a scalloped border, bending slightly outward opposite each 

 goblet; the supporting colls extend <>nt on the prolongation in a very 

 narrow strip; the sides of this cellular area are nearly parallel; niacnla 

 ovate, broadest anteriorly, about 215/* long; aperture elongate, slightly 

 curved. 



Body, genital pore situated between coxae II, genital groove moder- 

 ately distinct; aims broadly oval, transverse, about 215 x 187m, soft por- 

 tions of voider transversely striate, with numerous short pale hairs. 



Female. — Capitulum (Fig. 2)832/* in length; basis capitulidark reddish 

 brown, with considerable white on dorsal surface; 588/t wide; postero- 

 lateral angles moderately long; porose areas broadly elliptical, oblique, 

 rather close together at base; ventrally, basis capitnli is rather long and 

 narrowed at posterior ridge, which is prominent; palpi 488/* in length; 

 article II : >< 1 1 /x in length along internal margin, article III 17'2/j- along 

 internal margin; article I prominent ventrally, bearing four bristles along 

 internal edge, article II with seven such bristles, and article III with 

 three bristles; hypostome broad at tip narrowed proximally, with six 

 rows of teeth ventrally; the three rows of teeth on either side converge 

 toward base and diverge from the median line, the outer row is the 

 longest having about thirteen teeth; internal article of chelicerae 151/* 

 long, slender, with small external subterminal tooth, basal tooth on 

 external article large. 



Scutum (Fig. L' I 1.71 mm. long, 1.53 mm. wide, widest at eyes which 

 are moderately prominent, margin posteriorly is almost a regular curve, 

 there being no marked constriction behind eyes; capitular emargination 

 rather deep, scapular angles narrow but rounded; cervical grooves rather 

 deep anteriorly, converging, then diverging posteriorly, the divergent 

 portion very shallow, and disappearing one-third of the length of the 

 scutum from its posterior tip; most of surface of scutum covered with 

 white which lias a distinct greenish metallic lustre; red streaks along 

 cervical grooves, on scapular angles and around eyes, white is somewhat 

 broken with red on anterior portion between cervical grooves; rather 

 numerous small red points or minute punctures scattered over entire 

 scutum, a few somewhat larger punctures on scapular angles. 



I.egs and coxae dark reddish brown, a strip of white along the dorsal 

 sides of legs except on tarsi; scattering pale hairs on coxae and legs; 

 coxae I with long spurs, internal slightly longer than external; coxae II 

 and III with postero-internal angles slightly raised from body; coxae II, 

 III and IV with long, stout apical spines, trochanter I with short but 

 rather sharp subterminal dorsal prolongation; all tarsi tapering at tips. 



Stigma! plates (Fig. 6) of medium size, greatest dimension 5Cr_X from 

 anterior internal angle to tip of prolongation; broadly oval with a rather 

 long postero-dorsal prolongation extending at about right angles to a line 

 through the macula; plate with a highly chitinized slightly raised border, 

 widest in the external lateral angle where the border widens into a boss
