BREEDING HAUNTS OF GLOSSINA MORSITANS. 359 
At Sinombi, the Sinyama River is met by a tributary stream, and the valleys 
run north, south and west. Along these valleys and on the actual banks of the 
streams a number of fine shady trees are found which are in full leaf in August, 
and here the tsetses congregate. On the hills around, the forest is leafless and 
affords but little shade. Puparia, for the most part empty, were found at the 
bases of the shady trees, mostly on sharply sloping ground, but not invariably. 
The list of the situations where the puparia were found is as follows :— 
(7) One empty puparium found at the base of an unidentified tree, on the 
sharply sloping bank of the river; position shaded by bushes; soil sandy and

loose, with much humus, ete. 
(8) Baobab tree (Adansonia digitata) on sharply sloping bank of river. Thirty- 
nine empty cases and three live pupae were obtained, mostly under exposed roots 
on the sloping side. Soil loose and sandy, with abundant humus, ete. (Pl. XX, 
fig. 2). Two empty cases and one live pupa were taken from a small hollow in
