(From the Quick Laboratory, University of Cambridge.) 
(With 4 Text-figures.) 
The new species herein described are of interest, although we can 
only deal with females, as is so frequently the case with this genus. 
One species (I. kempi), allied to the North American I. angustus, comes 
from a hitherto unexplored region on the north-east frontier of India, 
having been collected by the Abor Expedition. Two species (I. daveyi 
and I. oldi ) are from Africa, and offer a peculiarity of structure in that 
they possess anal grooves having the form of a horse-shoe, an appearance 
only hitherto observed in three other species of Ixodes, all of which are 
African. The fourth species (I. ricinoides) is from China, and is allied 
to our I. ricinus: 
Ixodes kempi ? , from Kobo, Abor Country. (Indian Mus., Calcutta, 1247/17.) 
,, daveyi ¥ , from Rusvenzori, Uganda. (Imperial Bur. of Ent., 470.) 
,, oldi ? , from Komatendu, Sierra Leone. (Imperial Bur. of Ent., 604:) 
,, ricinoides ? , from Wen-chwan-hsien, China. (Our Collection, 1401, 1402.) 
Ixodes kempi n. sp. 1 
(Fig. 1.) 
Male: Unknown. 
Female : Hard parts blackish-brown (as in I. ricinus). (Dorsal 
aspect.) Scutum with pointed scapular angles, emarginate, longer than 
1 Named after the collector.
