Hosts : On the bird known as Burchelhs Coucal, C entropies burchelli. 
Habitat : Manhiga, Lourengo Marques District, Portuguese East 
Africa. 
The above description was made from four males, one engorged 
female, three engorged nymphs, and six engorged larvae, taken from a 
BurchelTs Coucai ( (Jentropus burchelli), shot at Manhiga, in the northern 
part of the district of Lourengo Marques, Province of Mozambique', on the 
3rd of June, 1908. It seems rather remarkable that all four forms, i.e. 
males, females, nymphs, and larvae should be found on the host at the 
same time. 
So far as we know at present only one other species of Ilaemapliysalis 
occurs in South Africa. This is H. leachi, a common pest of dogs and the 
transmitter of Piroplasmosis of the dog. II. afrveana can he easily 
separated from H. leachi by the following characters : — 
11 . leachi . — 
1. Male with body elongate and slender. 
2. A large tooth projecting posteriorly on both dorsal and ventral 
sides of the lateral prolongation of article 11 of the palpi, in male, female, 
and nymph. 
3. Females large and more or less ovoid in outline ; dorsal shield oval 
in outline. 
4. Shield of nymph pentagonal. 
5. Larva with palpi similar to those of the adults, bearing the promi- 
nent lateral prolongation of article II. 
II. africana . — 
1. Male smaller, lighter coloured, and not so elongate and slender, 
punctuations on the dorsal shield larger and fewer in number. 
2. No ventral posteriorly projecting tooth on article II of the palpi, 
and the dorsal tooth largely reduced. The same fact is true in the nymph. 
3. Females small and quadrilateral in outline ; the dorsal shield is 
nearly circular in outline. 
4. Shield of nymph nearly circular in outline. 
5. In the larva the palpi do not have such a prominent lateral pro- 
longation ; this prolongation is shorter and wider, making the palpi 
appear short spindle shaped. 
The type specimens are in my private collection.
