proved to constitute a separate genus. It seems to me that the differences 
are quite sufficient for that, and I have therefore followed Lahille in retain- 
ing it. 
There is only one species belonging to this genus in South Africa, 
Neumaniella transversale. I have never see a specimen, hut have followed 
Neumann in the following description : — 
NEUMANIELLA TRANSVERSALE. (LUCAS.) 
Python Tick. 
Ixodes transver sails, Lucas (1844, 1845). 
Aponomma transversale , (Lucas) (Neumann, 1899)., 
Plate XVI , figures n (a, 5, c, d). 
Male. — -Body hat, narrow in front, very wide behind, wider than long, 
3 mm. wide by 2.75 mm. long (rostrum not included). Shield reddish 
brown, glabrous, smooth, without punctuations or with punctuations very 
fine and few in number ; cervical grooves straight, parallel behind, then 
two large pits, and at the periphery five to seven short, radiating grooves ; 
marginal grooves not ver}^ apparent, but marking off a light coloured 
marginal area, narrow in front, wide behind, where it is divided into eleven 
poorly defined festoons. Ventral surface reddish yellow, concave, with very 
short, scarcely visible hairs * sexual opening opposite second inter-coxal 
space; sexual grooves very short; anus near the posterior third of the 
length of the body ; no anal groove ; ano -marginal groove well marked ; 
stigmatic plates nearly transverse, short comma shaped. Postman 1 mm. 
long, base large, a little wider than long, dorso-posterior angles fairly 
prominent ; mandibles [ XVI, n (a)] with inner apophysis bear- 
ing a process with two teeth, and with base elongate 
longitudinally, and nearly half as long as- the apophysis ; outer 
apophysis with four teeth, the posterior strongest, and the base of the 
apophysis narrowed to a point; hypostome [XVI, n (c)] wide, spatulate, 
emarginate at tip, which is furnished with a very large number of small 
denticles, extending over the anterior third of the hypostome ; two rows 
of seven to eight large teeth in each row along each outer margin ; palpi 
thick, third article equal in length to two-thirds of the length of the second 
article, both articles with a few hairs on their margins. Legs short, thick, 
chestnut brown in colour ; coxae rather strong, a short spine in the centre 
of the posterior margin of each; tarsi thick; tarsi IV twice as long as 
wide, each tarsus provided with two small terminal spurs, followed by a 
similar spur near the distal third of the ventral margin on tarsi II, III and 
IV ; tarsi I bears Haller’s organ in the middle of its length, false articula- 
tion near the middle of the length in tarsi II, III and IV [XT r J, n (d)\ ; 
short hairs on all of the articles. 
Female. — Body swollen ; very wide, ordinarily 1.5 mm. long by 2.5 
mini wide, but may reach a size of 6 mm. in length and 8 mm. in width ; 
glabrous ; reddish brown or dirty green in colour. Shield [XVI, n (b)] ; 
cordiform in outline, angles rounded, except the posterior angle, which is a 
little emarginate ; lateral margin very convex ; colour reddish brown ; no 
hairs and no punctuations ; cervical grooves deep, nearly straight, and 
pointed, reaching posterior margin, and dividing the surface into three- 
oarts, median of which is rectangular in outline, the laterals triangular, and
