IN THE PROVINCE OF MOZAMBIQUE, EAST AFRICA. 4] 
been through that portion of the district known as Maganja da Costa, and 
informs me that in nearly all parts of this region G. morsitans is to be found, I 
have examined his specimens, and find that he has both G. morsttans and 
G. pallidipes from Maganja. He also reports G. brev/palpis* from one locality 
in Maganja. Austen has belts located near Chinde, at the mouth of the 
Zambesi river, and also at the mouth of the Shiré river. These no longer exist. 
The coastal region is also quite free from fly. Cattle trypanosomiasis was 
present in herds at Mopea on the Zambesi in 1908-9, and also on the southern 
banks of the Zambesi to the westward, toward the Tete district, but a careful 
search in the adjoining regions failed to disclose any fly. The natives were quite 
ignorant of it. All the facts went to indicate that the disease had been intro- 
duced in cattle brought from Nyasaland and had then been spread through the 
herds by local biting flies such as Stomoxys or TABANIDAR. 
The Tete district, while not having as many fly-belts as one would be led to 
expect, has several well-known fly-areas in the central and northern parts. The 
western portion seems to be fairly free from fly. Drivers who have brought 
cattle across this portion, in the vicinity of Zumbo, from North Hastern Rhodesia 
into Southern Rhodesia, report that there is no fly until they arrive at the 
escarpment in Southern Rhodesia, some distance south of the Tete boundary, 
where the land suddenly rises to a higher level. Here in the kloofs fly is to 
be found. 
Dr. Sant’Anna has also recently visited the Tete district, and kindly gave us 
his notes on the fly-belts which he found. <A belt of G. morsitans exists on the 
road leading to the north from Tete to Villa Coutinho, near and north of the 
course of the Inyamandzi river, an affluent of the Revugwe river. A second belt 
was found near the Lingove river, another affluent of the Revugwe river. 
A third occurs about six hours south of Inyamandzi, while a fourth occurs two 
hours west of a place known as Muchina, in the same general region. 
The district belonging to the Companhia de Mocambique has several 
fly-belts. In the northern part there is apparently a considerable amount of fly. 
While the south bank of the Zambesi river is itself quite clean, tsetse probably 
occurs at several places some distance inland. ‘Trypanosomiasis has occurred 
among cattle along the river in the vicinity of Sena, but no fly is present at 
least within a considerable distance of the river, where the cattle graze. At 
Lacerdonia there is fly one hour’s distance south from the river. About 
half-way between the Zambesi and Beira, toward the coast, is a place known as 
Chirugoma, in the vicinity of which are fly-belts of both G. morsttans and 
G. brevipalpis. 
Twenty to twenty-five miles from Beira, near the railway line, is a belt of 
morsitans ; another belt occurs about thirty miles south of Sofala; a third 
is known to occur near the Rhodesian boundary in the vicinity of Melsetter ; 
* [In his manuscript the author refers to this species under the name of G. fusca ; but it is 
now recognised that the large Hast African Glossina, to which this name was formerly applied, 
is specifically distinct from the purely western G'. fusca, and it has been descrined as G. brevi- 
palpis, Newstead. In the British Museum there are specimens of this species taken at Bamboo 
Creek, on the Beira Railway, by Mr. L. E. W. Bevan, of Salisbury, Rhodesia ; this record has 
been added to the author’s map.—ED. |
