oil 
of the genus Haemaphysalis of the Ixodidae. 
Capitidum : base rectangular, twice as broad as long, with 
strong sharp cornua. Palps: article 2 fairly salient but not 
sharply angular externally; lateral contour of articles 2 and 3 
continuous ; no dorsal spines ; ventral border of article 2 having 
a somewhat prominent retrograde angle ; a distinct retrograde 
spine, directed inwards at the ventro-lateral angle of article 3. 
Hypostome 4/4 on its distal half, then 5/5, the additional teeth 
being median. (Thus in the specimen described, probably vari- 
able between 4/4 and 5/5.) 
Legs: a fairly strong blunt spur on coxa 1; shorter blunt 
spurs on coxae 2 and 3 ; a long sharp spur — longer than the 
width of the article — at the inner angle of coxa 4. Tarsi 4 rather 
short, about 3 times as long as broad, tapering gradually. 
Female : all yellow when young, the scutum a bright yellow 
when the body is dark and distended ; the largest specimen 
measured 8'5 mm. 
Scutum exactly as broad as long, lxl mm. in one specimen, 
•9 x '9 mm. in another, broadest at the posterior bright yellow, 
with numerous fairly large punctations. Cervical grooves long, 
concave externally, beginning somewhat behind the anterior border 
as fairly deep depressions and continuing faintly to the postero- 
lateral margin. No lateral grooves. 
Venter : spiracles white, circular, with blunt dorsal protu- 
berance. 
Gapitulum : base comparatively broader than in the f , and 
with short blunt cornua ; porose areas large, oval, converging 
anteriorly, their interval ecpial to their long diameter, a few
