the base of the rostrum ; punctuations unequal, a few large ones 
in median area and forming part of lateral grooves, hut the 
greater part fine and distant from each other ; eyes in the 
middle of the length or slightly posterior of middle ; cervical grooves 
■elongate, nearly reaching posterior margin ; lateral grooves deep and almost 
meeting cervical grooves at posterior end. Dorsal surface glabrous or 
.almost glabrous ; in the young female, four anterior grooves, sometimes not 
well marked, three posterior grooves. Ventral surface glabrous ; festoons 
.slightly marked ; stigma tic plates oval, with a short postero-dorsal pro- 
longation. Rostrum with base wider than long, lateral angles large and 
.sharp, giving it a width twice that of the posterior margin ; porose areas 
large, elliptical, close together ; palpi not so short and massive as in male, 
and not so angular on 'outer edge ; the three articles bearing spines as in 
male ; inner ventral margin of article I projecting inward ; hypostome with 
six rows of teeth of about 12 teeth to a row ; mandibles (X, k) with process 
of inner apophysis tridentate; 'but teeth not so pronounced as in male ; outer 
apophysis tridentate, anterior tooth sub-terminal and small. Legs rather 
slender, deep brown in colour ; coxae longer than wide, coxae II, III, and 
IV, with two small spines on posterior margins, as in male, but the outer 
spine is not so strong as in male ; stiff hairs on all the articles ; especially 
on dorsal and ventral margins of articles III to VI ; tarsi II, III, and IV 
with only one ventral spur, proximal spur represented by a blunt tuberosity. 
Nymph. — (Phaulixodes rufus.) Body elliptical, a little compressed, 
.greyish, reddish brown or blackish, often 5 mm. in length. Dorsal shield 
very small, elongate pentagon, lateral margins almost straight, not divergr 
ing very much ; surface irregularly reticulated ; cervical grooves diverging 
only behind ; eyes on lateral angles, near posterior third. Dorsal surface 
of abdomen with four anterior grooves, the outer ones shorter; three 
posterior gooves, the median straight and the outer ones curving outward. 
On the ventral surface , sexual pit, imperforated, opposite coxae II ; sexual 
grooves well marked ; ano-marginal groove long ; stigmatic plates circular. 
Rostrum very short, base a little widened behind insertion of palpi. 
Mandibles almost like those of female ; hypostome with two rows of teeth 
on each half ; palpi a little valvate, with a few scattered hairs ; articles a 
little prominent on the outer edges, article IV relatively long. Legs short, 
slender, coxae I with division not very deep ; the others as in female ; tarsi 
without spurs.

This tick is of very wide distribution over Europe, Africa, and Asia, 
even extending into Central America. It seems to be of fair occurrence 
in the Transvaal, but is confined mostly to the northern and eastern
