Notes on Ticks 
short, convergent, lateral grooves include two festoons and extend 
forward to two-thirds the body-length; posteriorly a median groove and 
two lateral depressions, two longitudinal grooves anterior to the latter 
extending forward to half the length; festoons short; punctations few, 
inconspicuous. Capituluni: 1. 0'4-0’5 mm., base sub-rectangular, wdth 
concave dorsal ridge connecting stout, somewhat convergent cornua 
having rounded points; base bulges ventrally. Palps longer than 
broad, being broadest at the distal end of article 2, Avhich is about a 
third longer than article 3. Hypostome broad, 4 : 4, with corona followed 
by 8 distinct teeth per file. Venter : genital orifice between coxae II; 
spiracle longer than broad, with recurved dorsal margin. Legs short, 
stout. Coxae I-IV each bearing a stout spur, longest on coxae IV 
and concave externally. Trochanter 1 with very large dorsal blade. 
Tarsi remarkable, the distal portion bulging dorsally and ventrally, 
tapering rapidly, bearing a spur. Pad half as long as the claws. 
Female (Fig. 6). Bodg (unfed), L. 2‘3 mm.\ with marginal groove 
including the second festoon and almost attaining the scutum. Scutum : 
/. 1'2-1‘6, IV. 1'4-1'6 mm., cordiform, cervical grooves not attaining the 
posterior border, postero-lateral border almost straight, few inconspicuous 
punctations. Capitnlum: 1. 0'8-0'9 mm., base broader than long, with 
sides angular, the antero-lateral borders converging, dorsal ridge concave, 
wavy, connecting short stout cornua; porose areas long oval, converging 
anteriorly, far apart, in some specimens separated by a median de¬ 
pression ; viewed ventrally, the base bulges markedly. Palps atypical, 
very long, with article 1 distinctly visible dorsally, article 2 about twice 
as long as 3, the palps being broadest at the juncture of articles 2-3. 
Hypostome broadly spatulate, 414 or 5 1 5, with emarginate corona, 
about 10 distinct teeth per file. Venter: vulva between coxae II when 
unfed, facing second intercoxal space when replete; spiracle as long as 
broad, somewhat angular, with slightly marked postero-dorsal angle. 
Legs resembling those of cT, the spur on coxa IV less developed.
