Indian Ticks 
Capitidum. Base about twice as broad as long, with long cornua, 
but not so long as in the cT ; porose areas rather large, oval, converging 
in front, separated by more than their diameter. Palps with the same 
characteristics as those of the I, but the ventral spur on article 3 
longer than the dorsal. Hypostome 4 j 4. 
Venter. Spiracle nearly circular, but rather pointed dorso-laterally. 
Vulva between coxae II and III. 
Legs. As in the </. 
Nymph. Without dorsal spur in article 3 of palp ; otherwise like 
the $ in such structures as are present. 
Described from 30 J" taken (in company with H. longipalpis) by 
Mr C. C. Dobell from Tragulus ineminna (the “Mouse Deer”) at Colombo, 
Ceylon, 3, vill, 1909, and 2 $ and numerous nymphs and larvae taken 
from Paradoxurus niger (Palm civet) at Colombo, and sent by 
Dr A. Willey, 16, ii, 1910. 
Though the sexes were taken from different hosts they correspond 
so precisely that there can be little doubt of their relation to each other. 
This species much resembles H. longipalpis in most respects, but it is 
easily distinguished by the capitulum. 
HAEMAPHYSALIS LEACHI var. INDICA, n. var. 
Differs from the type in the following respects: 
Smaller, and shorter in proportion to its breadth. The external 
lateral contour of the palp is slightly concave, and its second article, 
though hollowed over the scapula, is without the characteristic dorsal 
and ventral retrograde processes. Cornua feeble. The scutum of the 
female is shorter and more accurately oval than in the type, where 
the postero-lateral borders are somewhat concave. Hypostome 4 | 4. 
Otherwise as in the type. 
Male. 1-5 X ’8 ram. (without capitulum). 
Female (unfed). 1‘7 mm. long. Scutum '8 x '6 mm. 
Described from several specimens taken from a jackal (Canis aureus) 
in the Museum Compound, Calcutta (tubes -^ff-). 
The small size, less elongate form, and the absence of retrograde 
processes on the second article of the palps seemed, on first inspection, 
to indicate a distinct species, but the close agreement with the typical 
H. leachi in other respects prevents its recognition as anything more 
than a variety. It is perhaps worth noting that another African tick 
now widely spread in India— Hyalomma aegyptiuni —tends in that 
country^ to become smaller and less strongly characterised.
