SUPPLEMENTARY NOTES ON THE TSETSP:-FLIES

the river banks are swarming with cattle, and there are large encampments of herdsmen in the dry season. 
After the rains have commenced the fly is present on the river in sufficient numbers to be an annoyance 
to travellers, and continually bites the canoe-men. In the dry season, however, which lasts from October 
to April, it is much less numerous. 
' On the banks of the Benue River within the area in question almost the only species of game to be 
found is Kobus kob, which is very numerous indeed. West African buffalo, waterbuck, and reedbuck are 
met with in the swamps near the river ; but in the Benue Valley there are, in the immediate vicinity of 
the river, more kob than specimens of all the other species of game put together.' 
According to Dr. Brumpt, 7 on the Shari River and on the shores of Lake Chad 
Glossina decorsei (that is, Glossina tachinoides) seems to be exclusively confined to the 
water's edge. The author in question further writes as follows : — 
' The stab of Glossina decorsei is disagreeable, as is that of all the species of Glossina, but not very 
painful ; it causes some time after the bite a rather acute itching. Both sexes feed on blood . . . The 
natives of the Shari dread the effects of the bite of the Glossina on their herds ; like the inhabitants of 
many other countries, they have recognized the existence of a close connexion between the presence 
of nagana and the bite of this fly. Nagana is very widely spread on the Shari, where it was stated to occur 
by Morel, and met with again by the Chevalier Expedition.' 
Glossina pallidipes (Austen) and Glossina longipalpis (Wied.) 
There is nothing to add to the account of these species given in the Monograph. 
Additional specimens of the former, however, have been received from Colonel Bruce, 
including six individuals collected by Dr. Moffat at Simba, East Africa Protectorate, 
in a carriage on the Uganda railway, and six examples from Busoga, Uganda. The 
latter is a new locality for Glossina pallidipes. In addition to the foregoing, a long 
series of Glossina pallidipes from Kibwezi, East Africa Protectorate, has been presented 
by Dr. Nabarro. 
Glossina fusca (Walk.) 
Since the publication of the Monograph the specimens of this species in the 
National Collection have been augmented by a large number of examples from 
Kibwezi, East Africa Protectorate, received from Dr. Nabarro. Besides these, five 
specimens, also from Kibwezi, collected in a railway carriage by Dr. Moffat, have 
been presented by Colonel Bruce ; while three specimens, obtained on the Congo by 
the Trypanosomiasis Expedition of the Liverpool School of Tropical Medicine, have 
been received from Dr. Christy. Of the specimens last mentioned, which are all 
females, two were captured near Leopoldville, on December 26, 1903, and February 
6, 1904, respectively, while the third was taken at Leisha on April 14 last. With 
reference to these flies Dr. Christy has been good enough to furnish me with the 
following notes : — ■ 
' During our stay at Leopoldville three specimens of Glossina fusca were collected. One was brought 
in by a native alive, folded up in a leaf; another was captured among Glossina palpalis by our juvenile fly 
brigade, and the third was caught under the following circumstances : — On April \\, while sitting after 
dinner with two State officials, as late in the evening as 10 p.m., under the verandah of the Chef de Poste
