176 JAS. J. SIMPSON — ENTOMOLOGICAL 



River Moa had to be crossed by canoe. At this part the river is wide and 

 swiftly flowing, and there is a large island in the centre. While my loads were 

 being carried across this island, G. palpalis constantly attacked the carriers, and 

 the same species was troublesome at Manawa. From Manawa to Komatendu 

 the road is hilly and runs parallel to the River Moa ; at one place it passes close 

 to the junction of this river with the Meli. The country is densely wooded, and 

 Glossina fusca is by no means uncommon. At Komatendu a new species of 

 Tabanus was caught, along with T. besti var. arbucklei. Auchmeromyia luteola 

 was also obtained in the native town. 



On a mongoose {Mongos paludinosus) several ticks were found ; these accord- 

 ing to Professor Nuttall are " apparently Haernaphysalis leachi, but not typical, 

 being much shortened." A new species of Ixodes was also taken from the same 

 host, while the lungs contained several specimens of Porocephalus sp. 



Between Komatendu and Bendu the country is extremely hilly, and part of 

 the watershed between the Rivers Moa and Male has to be crossed. The hills 

 are heavily clothed with small trees and thick undergrowth, and Glossina fusca 

 may be caught at almost any part of this region. The same species occurs at 

 Bendu. From Bendu to Bunbumbo the road runs nearly parallel to the 

 River Male, the country being fairly level. Several G. palpalis were caught at 

 the River Loya, a tributary of the Male, near Bunbumbo. Stomoxys calcitrans 

 was also common at Bunbumbo. A well-made wide road runs from there to 

 Segbwima, on the railway ; no blood-sucking insects were seen during this 

 stage, but Tabanus pluto was caught at the town of Segbwima. 



(6.) Daru to Bo, via Bandasuma. 



The region now to be described lies south of the railway, and the route 

 traversed crosses three distinct river systems. From Daru to Bandasuma the 

 basin of the River Moa is followed, roughly parallel to the river. At Bandasuma 

 the River Moa is crossed, and the road then passes over the low watershed which 

 separates the Moa from the Kittam River ; this last-named takes its origin 

 south of the railway and flows almost due south into Lake Kassa, part of the 

 lagoon which separates Turner's Peninsula from the mainland. At Largo this 

 river is crossed, and near Tikonko the Bum or Sewa is again encountered ; the 

 river basin of the latter is followed until Bo is reached. 



The country between Daru and Juru is mostly level in the parts traversed by 

 the road, but hilly to the east and north-east. These hills form the watershed 

 between the Rivers Moa and Morro ; they are forest-clad, but the level country 

 is covered with short bush and is much under rice cultivation. 



The first town at which a halt was made was Jowati, which stands at the 

 confluence of two small streams which run into the River Moa. There Glossina 

 palpalis and T. besti var. arbucklei were both found in numbers, and from larvae 

 obtained in a "ju-ju" basin on a grave Stegomyia fasciata was bred out. It is 

 worthy of note that from one of the Glossina caught here a semi-deposited pupa 

 of a pale golden yellow colour protruded ; the date was 19th August. 



No blood-sucking flies were seen between Jowati and Mendikama, but at the 

 latter town both G. palpalis and T. besti var. arbucklei were caught. Between
