178 JAS. J. SIMPSON — ENTOMOLOGICAL 



Between Dumballa and Goraun the country is hilly and forms part of the 

 watershed between the Rivers Bum and Jong. Goraun stands on the River Lia 

 or Jaya, which flows into the Taia, which further on becomes the Jong. No 

 blood-sucking flies were seen there. At a small town called Kennema a pony in 

 good condition with no signs of trypanosomiasis infection was seen. 



From Goraun to Jarra the road passes along the bank of the River Lia for 

 the first part, and after that crosses numerous streams which run into the Bum 

 The country is composed of low rounded hills which are for the most part covered, 

 with grass with very little bush. Evidently the whole of this district is devastated 

 annually by fire in the dry season. At Jarra Tabanus rvficrus and Simulium 

 damnosum were caught. 



Between Jarra and Gendema, a small town situated on the bank of the Sewa 

 River, the road is undulating and numerous swamps and streams have to be 

 crossed. At Jagbwima, where the River Sewa is first encountered, Glossina 

 palpalis is common, and this species is to be found all along the river bank to 

 Gendema. At the latter town G. palpalis was found along with T. ruficrus, 

 T. besti var. arbucklei, and T. postacutus, Aust. i. 1. 



From Gendema to Kamboma the country consists of low rounded hills covered 

 with grass and low bush ; large granitic bosses occur in parts and there is 

 abundant cultivation. This area is extensively burnt in the dry season. No 

 blood-sucking insects were seen during this trek, and the only species obtained at 

 Kamboma was Simulium damnosum. 



Onwards from Kamboma to Tungea the country is more thickly covered with 

 bush, and there are numerous swamps in the valleys. Glossina fusca was captured 

 in the thick bush, and Hippocentrum murphyi in the swampy places where there, 

 was dense shade. The last-named species had not been described at the time of 

 capture, and extended notes were made by the writer, hut since then Austen has 

 named it, and given a long specific description* from specimens caught by 

 Dr. Murphy. It is unnecessary to quote my notes in full, but the following 

 observations will supplement the description given by Austen. Descriptive : — 

 The eyes of this species when alive are of a dull bronze green, and are traversed 

 by four yellow horizontal zig-zag bands. Habits : — It is the most vicious biter 

 yet encountered by the writer ; in its mode and determination of attack it reminds 

 one more of an infuriated wasp than a Tabanid ; its dart is sudden and it seems 

 to insert its proboscis before it actually alights. It appears to prefer shady 

 places similar to those in which G. palpalis is found, but especially in the vicinity 

 of swamps. 



At Tungea in addition to Glossina fusca, T. besti var. arbucklei was caught. 

 Between Tungea and Bewama the country is hilly and several swamps have to 

 be crossed ; it is covered for the most part with thick bush but is forest-like in 

 places. In the more densely-shaded portions Glossina fusca is found, while in 

 similar situations near the swamps Hippocentrum murphyi is common. At 

 Bewama G. palpalis was caught on a small stream, a tributary of the River 

 Taia, and in the town itself T. besti var. arbucklei and T. postacutus, Aust., i.l., 

 were obtained. A species of Amblyomma was found on grass.
