Indian Ticls 
Vente7'. Pregenital shield elongate, rathei’ indented anteriorly. 
Genital grooves gently diverging to reach the posterior border. Anus 
rather near the posterior border, the anal groove with the sides curved 
and slightly diverging. Genital orifice between coxae III and IV. 
Spiracles rather large, oval or slightly reniform. Legs long. Coxae I 
bidentate, like those of a RJiipicephalus or Hyalomma, protruding in 
front of the body and visible dorsally. Coxae II—IV with a slight 
external tooth and a more blade-like internal edge. All the coxae close 
together and occupying little more than the anterior third of the length 
of the body. Tarsi long and tapering, only slightly gibbous dorsally. 
Legs 4 extend beyond the posterior end of the body by their two distal 
articles. 
Female unknown. 
Described from two specimens in the India Museum, Calcutta 
(no. and no. ?), taken at Punkabani, Darjiling District, E. Himalayas 
(no host recorded). 
This fine species—the largest male Ixodes known—may very likely 
prove to be the I of Ixodes acutitarsus (Karsch) 1880, but it is unsafe 
at present to attribute it to that species. Its coxal armature is unique 
in this genus. 
RHIPICEPHALUS BREVICEPS, n. sp. 
(Fig. 3.) . 
Male unknown. 
Female. Apparently about half gorged, 5 mm. long, long-oval. 
Scutum. Long-oval (I'o x 1‘3 mm.), broadest at the eyes, which 
are large, black, well-defined, and rather nearer the posterior than the 
anterior border; dark and highly chitinised, with confluent punctations 
and rugae on the anterior half and small discrete punctations posteriorly. 
Cervical grooves rather faint, converging at first, then diverging, to 
disappear about the middle of the scutum. Lateral grooves curved, and 
reaching the posterior border, marking off a prominent external ridge 
finely punctate. 
Gapitulum. Excessively short; base three times as broad as long, 
with small shallow porose areas separated by more than their diameter. 
Palps no longer than in Boophilus. 
Venter. Vulva very anterior (somewhat ill-defined in the specimen) 
between coxae I and II. Spiracles medium, short-comma-shaped.
