182 JAS. J. SIMPSON — ENTOMOLOGICAL 



Between Sembehun and Senahu the country is fairly level, swampy in places, 

 and covered with low bush. At Senahu the following were caught : — G. palpalis, 

 T. fasciatus, T, besti var. arbucklei, and a new species of Haematopota. 



From Senahu to Rotifunk (on the railway) the country is undulating and is 

 covered with low bush with abundant oil-palms. G. palpalis was caught at the 

 River Male, and T. besti var. arbucklei not far from Rotifunk. At this town one 

 male specimen of Tkaumastocera akwa, a very rare species, was obtained. The 

 following note on the colour of the eyes in the fresh specimen was made at the 

 time of capture. " The upper two-thirds of the eyes is yellow with irregular 

 bronze spots, while in the lower third the pattern is the same but the colours are 

 reversed ; in both cases the spots are irregularly disposed." 



(9.) Rotifunk to Waterloo via Rokell. 



Rotifunk stands on a small river, the Bumpe, which joins the River Walle, 

 on which Senahu is situated, before it enters the sea. From Rotifunk to 

 Robarri the country is undulating and covered with low thick scrub ; there 

 are extensive clearings for cultivation and numerous swamps. All along this 

 road Tabanus besti var. arbucklei was plentiful. At Robarri, which stands on 

 the Ribbi River, the vegetation is much thicker and continues so to Rokell. 

 Glossina fusca was caught at several places in this region, along with T. besti 

 var arbucklei. 



Rokell is situated on the left bank of the river of the same name, opposite 

 the town of Mabile. Large canoes ascend from the sea to this town, but 

 although the tidal influence is felt there, it is not brackish water and con- 

 sequently there are no mangroves. G. palpalis is to be found all along the 

 river banks, and T. besti var. arbucklei is very common. 



Between Rokell and Ropat the road follows the river for the greater part of 

 the way at varying distances from it. The same two species mentioned above 

 were caught there, but in addition to these Tabanus fasciatus was also seen. 

 From Ropat to Songo Town the country is covered with low bush and there is 

 abundant cultivation. T. besti var. arbucklei and T. fasciatus were both plentiful 

 along this road. 



At Songo Town Rhipiceplialus sanguineus was found on dogs, and at Newton 

 Station Haemaphysalis leachi was taken from a bush-shrike (Dryoscopus turetii) 

 shot there. The road from Songo Town to Waterloo follows the railway ; at 

 the latter town G. palpalis and T. fasciatus were obtained. 



(10.) The Peninsula :— Waterloo to Freetown, via Kent. 



The road from Waterloo to Kent, which is situated at the extreme south-east 

 point of the Peninsula, passes along the base of the mountains from which Sierra 

 Leone takes its name. With the exception of G. palpalis at Kent no blood- 

 sucking flies were seen on this trek. 



A visit was made to a small group of islands known as the Banana Islands, 

 which form a continuation of the Peninsula ; there are only two towns of any 

 size on these islands, namely, Dublin (Plate XXII, fig. 2) and Ricketts ; G. 

 palpalis was found to be common along the beach and in both these towns.
