804 REPORT OF THE HARVARD AFRICAN EXPEDITION 
Aponomma laeve Neumann 
Aponomma laeve Neumann, 1899, Mém. Soe. Zool. France, XI, p. 190 (7 9; Patagomia, Amon- 
zette (?), and off Dasypeltis fasciolata at Banana, Belgian Congo); 1911, ‘Das Tierreich, Liet. 
26, Acarina, Ixodidae,’ p. 95 (<7 9). Nuttall, 1916, Bull. Ent. Res., VI, 4, p. 339. 
Liperia.— Paiata, one male and one female, off a snake, Dendraspis viridis 
(Hallowell), October 18, 1926 (D. Linder). 
BELGIAN Conco.—Mai Ivwi, north of Ruchuru, one female, off a snake, 
Bitis arietans (Merrem), March 31, 1927 (R. P. Strong), together with Ambly- 
omma marmoreum. 
TANGANYIKA TERRITORY.— Zengeragusu, forty miles from Mkalama, off a 
snake, Dasypeltis scaber (Linnaeus) [‘‘this snake was literally covered with 
ticks, seventy-five of which I collected” (A. Loveridge, 1923, Proc. Zool. Soc. 
London, p. 881)], November 3, 1921 (Arthur Loveridge). Kilosa, off Rham- 
phiophis oxyrhynchus Reinhard, May 20, 1923 (Arthur Loveridge). 
Two species of the genus Aponomma occur in the Belgian Congo: A. exor- 
natum and A. laeve. Only A. laeve is known thus far from Liberia. 
Hyalomma aegyptium albiparmatum P. Schulze 
Hyalomma aegyptium albiparmatum P. Schulze, 1919, Sitzungsber. Ges. Naturf. Fr. Berlin, pp. 194 
and 196 (&@ 9; Tanganyika Territory, without more definite locality). Chodziesner, 1924, 
Zool. Jahrb., Abt. Syst., XLVII, p. 553 (@ 9). 
Hyalomma aegyptium Donitz, 1910, Denkschr. Med.-Naturw. Ges. Jena, XVI, Pl. XVIa, fig. 4 (#7). 
(Not Acarus aegyptius Linnaeus). 
Kenya CoLony.— Ithanga Hills, near Lake Naivasha, several males and 
females, off buffalo, Syncerus caffer (Sparrman) (W. R. Zappey). 
I have followed Miss Margot Chodziesner’s recent revision of the genus 
Hyalomma in referring these specimens to the subspecies albtparmatum.1 I am, 
however, by no means satisfied that the distinction between H. a. albiparmatum 
and H. a. impressum Koch is based upon more than individual variation; it 
is probably not of subspecific significance. In the lot from Ithanga most males 
have a white spot on the “‘parma,”’ or median dorsal festoon, but others lack 
this spot. 
According to Miss Chodziesner, H. a. albiparmatum was known only from 
Tanganyika Territory, although she lists it also from Ruanda, which is now 
part of the Belgian Congo. Hyalomma aegyptium has also been recorded from 
several other localities in the Belgian Congo (Kasongo; Mandoko; Kamima, 
Lomami; and Elisabethville). Probably all these specimens belonged to the 
subspecies H. a. albiparmatum, which I have recognized in a lot from Man- 
doko. Miss Chodziesner identified as H. a. impressum specimens collected by 
vy. Falkenstein at Chinchoxo, at the mouth of the Shiloango River, in the Portu- 
guese territory of Cabinda.”

der Gattung Hyalomma Koch.’ Zool. Jahrb., Abt. Syst., XLVI, pp. 505-572, Pl. VII (map). 
2 Chinchoxo lies in 5° 15’ lat. S. and 12° 15’ long. E. and is not in the Gaboon, where Miss Chod- 
ziesner places it on her map. Hyalomma aegyptium is a species of the savanna and there is no evidence 
that it has ever been found in the West African rain forest.
