groove stopping at the penultimate or antepenultimate festoon ; festoons- 
well marked ; punctuations deep, distant ; hairs scattered, rather long. 
Rostrum as in male, often a yellow spot between the porose areas ; long 
hairs on the palpi. Legs as in male. Engorged female can reach to 
15 mm. long by 11 mm. wide. 
Nymph. — Form of the female, shield relatively wider ; yellow bloom 
less extended. 
Habitat. — Cape Colony. 
Hosts. — Tortoise, deer. 
I have not seen this species, and have taken the description from 
Neumann. 
Genus APONOMMA, NEUMANN. 
Ixodes (ex. p.), Latreille (1796). 
Opiiiodes, Murray (1879). (Name preoccupied.) 
Aponomma, Neumann (1899). 
No eyes. Base of rostrum usually pentagonal, with latero-dorsal 
edges very short. Palpi long. Male with body wider or almost as wide as 
long ; ventral surface naked ; sexual grooves very divergent behind, anal 
groove semi-circular or pointed, opening in front, joining the sexual 
grooves ; ano-marginal grooves median ; dorsal shield covering all the 
upper surface, and usually marked with metallic green spots ; stigmatic' 
plates comma-shaped. Shield of Female shorter or scarcely longer than 
wide, usually marked with metallic green spots, disposed in. a- triangle ;; 
grooves on the ventral surface as in the male ; stigmatic plates shorter, 
less attenuated at the postero-external extremity. 
This genus occurs almost exclusively on snakes and lizards, although 
Aponomma exornatum is reported as having been found in South Africa on 
a dog. From the colouration and grooves on the ventral surface it would 
seem to be closely related to the genus Amblyomma. It differs from that 
genus, however, by the absence of .eyes and the form of the body. The 
absence of eyes and length of rostrum have generally made species of this 
enus rank among the Ixodes , from which they differ, however, by the 
enerai conformation. Only three forms are reported from South Africa. 
Male. 
A. Shield marked with nine metallic green spots . . .. exornatum.. 
A A. Shield uniform, pale brownish, without metallic green spots. 
B. Tarsi II, III, and TV attenuated at extremity 
laeve capense 
BB. Tarsi with a bosse at extremity . . . . . . latum.. 
Females. 
A. Shield marked with three metallic green spots ; shield as long or 
longer than wide ; punctuations fine, close . . . . exornatum.. 
A A. Shield uniform, reddish brown, without green spots ; wider than 
long ; punctuations small and few. 
B. Coxae I with blunt, flat spurs, punctuations on dorsal shield 
obsolete latum.. 
BB. Spines on coxae I sharp ; punctuations small and few 
laeve capense ..
