212 JAS. J. SIMPSON—ENTOMOLOGICAL 
itself is surrounded by bush, and the rest-camp, which is situated about 400 yards 
from the river, is separated from it by about 150 yards of clearing. In spite of 
this, however, numerous G. palpalis were seen in the camp, but these may have 
followed the native water-carriers from the village. Auchmeromyia luteola was 
also common in the camp. My pony had been waiting here for me for some days 
during the trip in the Bintang Creek, and on my return several /Zyalomma 
aegyptium were found on it. The road from Albreda to Alijamadu runs parallel 
with the river bank the whole way, passing through Lamin, Tubab Kolon, and 
Sita Kunda. The nature of this part of the country may be described as open 
and park-like in character and there is extensive clearing and cultivation around 
all the towns and villages. Towards Alijamadu, there are large clusters of 
thick bush and Borassus palms similar to those described at Cape St. Mary. 
These may well be palpalis-haunts. The headman of this village, who is extremely 
intelligent, ventured the information that tsetse and large Tabanids may be seen 
here even in the dry season, but are much more abundant during the rains, 
as also are mosquitos. No horses are kept, and only a small herd of cattle, both, 
but especially the former, being subject to a form of disease the description of 
which was very suggestive of trypanosomiasis. I saw one tsetse in the camp, 
and although not certain, am strongly of opinion that it was Glossina morsitans. 
The dogs in this village seem to suffer badly from ticks, and the following species 
were obtained: Rhipicephalus sanguineus, Hyalomma aegyptium and Haema- 
physalis leachi. Bed-bugs (Cimex rotundatus, Sign.) are also very common in 
the native houses ; these the headman brought to me with great pride. 
Shortly after leaving Alijamadu for Berrending, a belt of dense bush is en- 
countered ; this is immediately followed by an extensive swamp intersected by a 
creek, which is bridged. This creek is fringed by mangroves, which extend to 
the river, and is doubtless a palpalis-area. From this onwards to Bakkendik, 
the road passes through dense bush and seems a likely abode for tsetse. Round 
the town of Bakkendik itself, there is a considerable clearing and abundant culti- 
vation. Quite a moderate herd of cattle was seen here, but the natives say that 
the rate of mortality is high. After leaving Bakkendik, the road passes through 
thin open bush and long grass, which is burnt in the dry season, but after about 
two-thirds of the way to Bintang has been passed, very thick bush with aerial 
creepers and a dense undergrowth of low palms, ferns, etc., is encountered. This 
is the top of another creek, and there are numerous pools of stagnant brackish 
water in the dry season. Glossina palpalis was caught here. The rest-camp 
lies about half way between Berrending and Buniadu. At Berrending, I saw a 
small girl with marked signs of advanced sleeping-sickness, and the chief, on 
being questioned, stated that the natives had some months previously assigned 
this case to “ceeno jankaro” ; they do not fear it and the girl lived as usual with 
her family. The road from Bakkendik to Berrending skirts the edge of a dense 
forest—the only one in the Colony—already described on page 190. The main 
route from Berrending to Duniajoe is vid Essau, but there is a bush-path which 
runs through M’Bollett, and as this traverses the outskirts of the forest, I decided 
to go by it in the hope of seeing Glossina fusca, because, if this species does 
occur in the Colony, it must almost certainly be in this region. The path to
