S00 REPORT OF THE HARVARD AFRICAN EXPEDITION 
corded as mites by Allen and Loveridge, 1927, Proc. Boston Soc. Nat. Hist., 
XXXVIII, p. 419); also off a rodent, Otomys kempi Dollman, at Nyingwa, 
Uluguru Mts., Tanganyika Territory, October 18, 1926. 
A hexapod larva and two nymphs of a species of Zvodes were found on 
a shrew, Scutisorex congicus Thomas, at Bumba, Belgian Congo, December 
31, 1926; a nymph also on a tree squirrel, Funisciurus pyrrhopus leonts 
Thomas, at Lenga Town, Liberia, August 13, 1926, and off Aethosciwrus poensis 
musculinus (Temminck) at Paiata, Liberia, October 1926. 
The above records of larvae are of interest because they indicate the ex- 
istence in Liberia of a species of /vodes, a genus of ticks not yet reported from 
that country. 
Six species of Jxodes are known from the Belgian Congo: J. rasus Neumann, 
I. rubicundus var. limbatus Neumann, I. ugandanus Neumann, I. cavipalpus 
Nuttall and Warburton, J. daveyi Nuttall, and J. stemplex Neumann. 
Amblyomma tholloni Neumann 
Amblyomma tholloni Neumann, 1899, Mém. Soe. Zool. France, XII, p. 242 (% 9; off elephant, 
Congo; Upper Ubangi; regions of Lake Nyasa and Lake Tanganyika); 1911, ‘Das Tierreich, 
Lief. 26, Acarina, Ixodidae,’ p. 81 ( ¢?). Nuttall, 1916, Bull. Ent. Res., VI, 4, p. 338. 
Robinson, 1926, ‘Ticks, Part IV, Amblyomma,’ p. 249, figs. 123-124, Pl. VI, fig. 1 (0 9). 
LrpErta.— Paiata, several males and females, off elephant, Loxodonta afri- 
cana cyclotis (Matschie), together with Dermacentor circumguttatus, October 
10, 1926. 
BruGian Conco.— Ingerosa near Irumu, several males and females, off 
Loxodonta africana, May 24, 1927 (R. P. Strong). Karibumba near Beni, off 
Loxodonta africana, March 21, 1927 (H. Coolidge). Semliki Forest, near old 
Beni, off Loxodonta africana, May 18, 1927 (R. P. Strong). 
This appears to be the most widely distributed of the elephant ticks, being 
known from Sierra Leone, Liberia, Cameroon, Portuguese Congo, Belgian Congo, 
Uganda, Anglo-Egyptian Sudan, Tanganyika Territory and Nyasaland. Most 
of the large series seen by Robinson came from elephant; but he saw also speci- 
mens off a leopard, and Neumann lists the horse and an undetermined species 
of antelope among the hosts. In the Belgian Congo this tick is quite common 
(J. Schwetz, 1927, Rev. Zool. Afric., XV, 1, p. 92).
