126 New Species of Ticks 
(hence aciculifer ) longer than the ai’ticle itself, and narrow from its 
origin ; slight progressively diminishing trochantal spurs; tarsus IV 
tapering rather abruptly ; pads rather long. 
Female : Scutum : Cordiform, slightly longer than broad (0'8 x 0 7 
mm.), widest ^ from antei’ior end; punctations (in the single speci¬ 
men, which is young and apparently not fully chitinised) small and 
inconspicuous ; cervical grooves well marked, slightly converging, visible 
for about § of scutum ; emargination fairly deep. 
Gapitulum: Basis much broader than long, cornua strong ; porose 
areas oval and far apart; palps as in the </, especially as regards their 
internal contour, but the dorsal protuberauce on article 3 is more 
marked and pointed, almost amounting to a spine; hypostome 4 4. 
Fig. 5. H. aciculifer $ , capitulum (dorsal and ventral aspects), scutum, anus, spiracle, 
coxae and trochanters. (N. Cunliffe, del.) 
Venter: Spiracle sub-circular; anal groove slightly ogival. 
Legs: Coxa I with fairly sharp internal spur; coxae II-IV with 
slight protuberance near the middle of the posterior border, strongest 
on coxa IV; tarsi as in the </. 
Described from 1 </ and 1 $ taken, in company with Rhipiceplialus 
appendiculatus, from Cobus thomasi (an antelope), on the N.E. shore of 
Lake Edward, Uganda, x. 1911, by S. A. Neave.

The entire absence of anything in the $ corresponding to the long, 
needle-like spine on coxa IV of the caused some hesitation in 
attributing these two specimens to the same species, but they agree 
very completely in"general structure, especially in the conformation of 
the palps. In those species in which the has a long spine on coxa IV, 
this is always much reduced in the $.
