﻿RESEARCH IN BRITISH WEST AFRICA. 161 



Dr. W. A. Lamborn, who has collected extensively on the Oni River. The 

 following blood-sucking flies have been received from him : Glossina caliginea> 

 G. palpalis, G. nigrofusca. Tab anus fascialns, T. secedens, T. socialis, T. thora- 

 cinus, Chrysops longicornis and C. silacea. With regard to the last-named 

 species he says : " This is the commonest biting fly found in the houses at Oni 

 Station on Lekki Lagoon." Of the three species of Glossina which occur in 

 this region G. caliginea appears to be by far the most abundant. 



(9) Ijebu-Ode. 



This district lies to the north of the western portion of the Epe district. The 

 country is undulating and for the most part covered with thick forest ; there are 

 no hills of any importance, and the whole region is well watered by small streams 

 and several large rivers. These latter are the higher reaches of those mentioned 

 in the Epe district. 



Bush-cow and some of the larger antelope are found on the Oni river and 

 the surrounding country, but on the whole the district is too thickly forested for 

 game to be abundant. Crocodiles are scarce. Nothing is known of the insect 

 fauna of this district. 



(10) Ondo. 



The district of Ondo is much larger than any of those just mentioned ; it 

 lies to the north of the eastern half of the Epe district, and extends northwards 

 to Ilesha. The country is hilly and undulating, and there are several large 

 dense forests. To the north are the Idanre Hilis, a range of granitic and gneissic 

 rocks, the surrounding country being precipitous on all sides. These hills form 

 the watershed between the river system of the eastern half of this Province 

 and the system of the western half of the Central Province. The whole 

 country is well watered, and there are several large rivers, the most important 

 of which are the Oni, the Owena and the Onishere. The principal creek runs 

 from Agbabu to a point where the Arogbo Creek flows westwards to Mahin 

 and eastwards to Arogbo, and is navigable for steam launches. 



Elephant and bush-cow are found in the Onishere and Idanre forests ; small 

 antelope and leopard in the Ondo and Akure forests ; while crocodiles abound 

 in the lagoons. Sheep, goats, pigs, and a small breed of cattle to which I 

 shall refer later, are to be found in most of the villages. 



The part of this district traversed by the writer was from Igbara-Oke 

 through Akure to Owo. The only blood-sucking insect obtained was Ctenoce- 

 phalus canis from goats at Akure. The forests of this province are probably 

 the largest in the Colony, and would well repay examination from an entomo- 

 logical point of view. 



(11) Oshogbo. 



North of the districts just discussed lie Oshogbo and Ilesha, which extend 

 to the Northern Nigerian frontier. Politically, Oshogbo is a sub-district of 

 Ibadan, but for the present purpose it merits separate consideration, chiefly 

 from the fact that the insect fauna of this area is, after Yaba, the best known 

 in Southern Nigeria. Dr. T. F. G. Mayer, who was stationed here for some
