of the genus Haemaphysalis of the Ixodidae. 517 
articles 2 and 3 unbroken ; no dorsal spines ; a small sharp spine 
under article 3. Hypostome 5/5, with hardly any corona. 
Legs : a short sharp conical spur on all the coxae, longest on 
coxa 4. Tarsus 4 rather short, tapering to a sharp point, pad long. 
Descriptign based on two gorged $ at the British Museum, in 
a tube labelled Haema'physalis papuana. 
Haemaphysalis bispinosa, Neumann 1897, non 1901 and 1902. 
Syn. H. bispinosa, Warburton 1907. 
Male: 2 x l'3mm., yellow or brown (in well-chitinised speci- 
mens), long oval, broadest in the middle, glabrous, uniformly 
punctate with medium inconspicuous punctations; cervical grooves 
very faint, lateral grooves long, well-marked, ending behind spi- 
racles; festoons very long. 
Venter : spiracles white, oval, broadest posteriorly, almost with- 
out dorsal protuberance. 
Gapitulum : base fairly long, broadly rectangular, with straight 
sides and moderate cornua; palps only slightly salient, articles 
2 and 3 about equal in size and equally angular externally; no 
spines on article 2, a short, sharp retrograde spine at the middle 
of the dorsal border and at the middle of the ventral border of 
article 3. Hypostome 4/4 with equal teeth. 
Legs : a moderate, sharp spur on coxa 1; a very slight pro- 
tuberance on coxae 2 — 4. 
Female: scutum yellow or brown, nearly circular, 1 x'9 mm. 
with unbroken contour; cervical grooves beginning rather behind 
the anterior margin as fairly deep furrows which converge and 
then curve outward, almost reaching the postero-lateral border; 
numerous regularly distributed punctations of medium size; 
no lateral grooves. 
Venter : spiracles white, nearly circular, practically without 
dorsal protuberance. 
Gapitulum: base broader than in the f, the sides straight, 
the cornua short and blunt; porose areas fairly large, far apart, 
oval, diverging anteriorly, not very clearly defined. Palps as in 
the f ; hypostome 4/4, with teeth of equal size. 
Legs: coxae as in the f ; tarsus 4 long (at least 4 times as 
long as broad), tapering very gradually. 
Description based on numerous specimens from India and 
Ceylon, where it appears to be common. 
N.B. It appears to us that Neumann has wrongly degraded 
his species II. bispinosa to a synonym of II. hystricis. Our ac- 
quaintance with the latter species rests solely on a female kindly 
lent us by Neumann and another female which we have examined in 
the British Museum. If this, as we believe, be the true hystricis
