? . Palpi flat dorsally, with convex margin; tooth 
on first segment well developed. Scutum : brown, 
eyes flat, belly uniform colour. Scutum as broad as 
long, or a short oval ; anal margin not fringed with 
white. Scutum : with distinct, somewhat unequal, 
fine punctations. Marginal furrow clearly marked. 
Porose areas as a rule separated by twice their diameter. 
Pathogenicity. —Transmits P. parvum (p. 283). 
(2) Eu. simus. — 3 . Marginal furrow single, the 
median and accessory furrows in front of the hind 
margin very slightly, if at all, indicated (characteristic). 
Marginal festoons are long, and are separated by deep 
furrows. Adanal shields not pointed. Ext. spiniform 
‘ shield ’ present. Eyes flat, large, and yellow. Scutum 
brilliant reddish brown ; punctations large and equal, 
arranged more or less in four rows with or without 
additional fine, hardly visible, punctations. 
3 . Eyes flat, scutum broader than long, puncta¬ 
tions distinct, unequal, the fine ones little visible. 
Porose areas separated by a distance equal to their 
diameters. Lateral angle of the rostrum not con¬ 
spicuous. It is the ‘ black-pitted tick 5 of S. Africa. 
Pathogenicity. —Transmits P. parvum. 
(3) Eu. evertsi. — 3 . Shield shagreened; uniform 
deep brown colour with red border. Marginal furrow 
simple. Eyes spherical. Characteristic are the legs, 
saflron red. Eleven marginal festoons unbordered with 
white as in Eu. capensis. 
2 . Shield shagreened. Eyes brilliant and 
spherical. Legs red. The ‘ red-leg tick ’ of S. Africa. 
Pathogenicity. —Transmits P. equi. Larvae and 
nymphs which have fed on infected animals transmit 
in the adult stage (p. 286). 
Bionomics. —Passes the first moult on, the second 
moult off the host. It attacks the regions around the anus.
