326 JAS, J. SIMPSON—-ENTOMOLOGICAL 
by Dr. W. D. Inness. The following species from the surrounding districts were 
also collected by Dr. W. D. Inness :-— 
Glossina palpalis at ‘ Yelwa Ford on the Kontagora River” (5. x. 09). 
Glossina tachinoides ,, _“* Kontagora River, 1 mile 8. W. of town ” (26. viii. 09), 
- . » “Valley of Kontagora R., between Mudangi and 
Adala” (7. viii. 09). 
s 3 . ‘Banana plantation at Adala, on Kontagora R.” 
(8. viii. 09). 
= 3 3 ‘* Yelwa Ford, Kontagora R.” (5. x. 09). 
Glosina submorsitans ,, the first three lidalittes cited for G. tachinoides, on 
the same dates. 
Mr. P, de Putron, the Assistant Resident at Bussa, also collected specimens of 
G. palpalis at Kulfu, and Tabanus par at Jeri. Both these places are in the 
Bussa District of the Kontagora Province. All the above records have been 
included on ihe map. 
From Kontagora to Yelwa, the country varies in character at different parts, 
and is much more hilly than the previous section, especially when nearing the 
valley of the Niger. The first part of the road, namely to Osubu,* is fairly level 
and swampy, with a considerable amount of scrub. One specimen of Glossina 
palpalis, the first on this trip, was caught close to one of the swamps, in a cluster 
of dense bush. The headquarters of the Kontagora Province used to be at 
Osubu, but were removed in 1905 for various reasons, one of which, according to 
the Resident, being the enormous mortality of horses in the station. The roads, 
grass and bushes were swarming with small ticks, and a walk in the grass resulted 
in one’s legs being simply covered with them; it is often stated that these will 
not bite man, but the writer’s experience does not in any way bear this out. 
The species found were Rhipicephalus sanguineus, R. simus and Haemaphysalis 
leachi. G. palpalis occurs in numbers in Osubu. 
The road to Massamabu passes through open country with abundant high 
grass and thin scrub. About half-way, the River Kontagora, which runs south- 
west and joins the Niger nearly opposite the junction of the River Oli with the 
latter, has to be crossed by means of rafts. While waiting here, I secured one 
specimen of G, palpalis. At and around Massamabu the following blood- 
sucking insects were caught :-—Tabanus subangustus, Haematopota bullatifrons, 
H. lacessens, H. puniens, Glossina palpalis, G. tachinoides and Simulium sp, 
Simulium was especially troublesome between 4 and 6 in the evening. When 
this insect has finished feeding, a small drop of blood is generally left adhering 
to the wound. The position of the bite is afterwards indicated by a bright 
red spot, surrounded by an irregular discoloured purplish area which remains for 
several days. 
Heavy rain fell throughout the night, but early in the morning it cleared up. 
No sooner, however, had we started for Anaba than a downpour commenced, and 
continued the whole day. Work was impossible, so a halt was made at Ibeto, 
No flies of any description were seen, About 10 o’clock next morning, the rain 
having partially stopped after 39 hours’ continuous downpour, a start was again 
* Osubn is not marked on the map, but lies about four miles from Kontagora.
