APONOMMA LATUM. (KOCH.) 
Amblyomma latum , Koch (1844, 1847). 
Aponomma politum , Neumann (1899). 
Amblyomma laeve , Neumann (1899). 
Aponomma latum (Koch) (Neumann, 1901). 
Male. — Body oval, flat, 5 mm. long (without rostrum), 4 mm. wide, 
ochreous yellow in all its parts. Shield covers all the dorsal surface, uni- 
colour, glabrous ; cervical grooves short, concave ; no lateral grooves ; 
posterior festoons elongated, with separations deep and curved outward ; a 
few punctuations, very fine, more sparsely scattered about the periphery of 
the shield ; on each margin at the level of legs IT, a smooth area, repre- 
senting an obsolete eye. Ventral surface clothed with very short, trans- 
lucent hairs ; stigmatic plates comma-shaped. Rostrum 1.3 mm. long ; 
hypostome with three rows of teeth on each half ; first pair of coxae pro- 
vided with two short, blunt spines ; coxae III with a large dentate plate ; 
the other coxae unarmed ; tarsi short, with a bosse near their outer 
extremity ; claws long, caruncle short. 
Female. — As wide as long (2.7 mm.), hut widest behind ; when fully, 
engorged it may become as much, as 9 mm. long by 6.5 mm. wide ; colour, 
reddish brown. Shield reddish brown, uni-colour without spots, heart 
shaped, almost as wide as long, smooth and shining, punctuations very 
fine, almost invisible ; cervical grooves reduced, only extremities present. 
Dorsal surface deep reddish yellow, a little lighter on the edges,, and 
smooth, a little shining ; usual grooves replaced by shallow depressions ; 
jDosterior festoons rather prominent. Ventral surface lighter coloured, than 
dorsal, a few short hairs and punctuations present. Rostrum reddish in 
colour ; base rectangular, almost twice as wide as long ; hypostome 
elongate, rounded at the tip, three rows of teeth on each half ; palpi long, 
flat, narrow, hairs present ; porose areas not very deep. Legs slender, of 
medium length ; coxae like those of male, tarsi longer than those of male, 
and bosse less prominent. 
Hosts. — Serpents, Python molurus. 
Habitat. — East Indies, Durban. 
This species I have never seen. The description is compiled from those 
given by Neumann. 
Genus NEUMANIELLA. (LAHILLE.) 
N.eumaniella, Lahille. 
Body wider than long ; narrow in front, and very wide behind ; palpi 
elongate, but shorter than in Aponomma ; no eyes ; sexual grooves very 
short or entirely lacking ; no anal groove. 
This genus was established by Lahille on the species Aponomma 
transver satis, Lucas, a South African species. It is very closely related to 
Aponomma, and differs from it mainly in the shape of the body, wider than 
long, whereas the species of Aponomma are as long as wide, and by the very 
short sexual grooves on the ventral surface, or entire absence of them, and 
the entire absence of the anal groove. When Neumann described this type 
species (1899) he drew attention to the fact that it differed considerably 
from the typical Aponomma, and suggested that it might eventually be
