Voi River, about 2,c00 ft. (June, 1905): a fine male of 
Papilio dardanus (merope), sub-sp. t2bullus. 
Nairobi, 5,500 ft. (Dec., 1904): sixteen butterflies, of which 
7 are catalogued. 
Kilimanjaro: several sets of butterflies and a few moths 
from this interesting mountain were presented by the same 
generous donor :— 
Slopes of the mountain (Dec. 15-31, 1905); native col- 
lectors: 57 butterflies and 1 moth, of which 37 are catalogued 
and several others added. A useful and varied series of 
specimens, 
S.E. slopes ; Marang State (Sept., 1905); collected by the 
donor: 18 butterflies, of which 11 are catalogued. 
S.E. slopes; Mamba State (Sept., 1905); collected by the 
donor: 135 butterflies, of which 51 are catalogued and many 
others incorporated. The series includes a fine set of Colas 
electra:—5 males, 8 orange females, and 8 white females ; 
also a set of 8 dry-season (one from Marang State), I inter- 
mediate and 1 wet-season, Precis sesamus, captured Sept. 19-25. 
Nearly all except the wet form were more or less chipped 
and worn, and had evidently been upon the wing for a con- 
siderable time. The single wet-season specimen was a male, 
and it was captured 27 coz¢# with a worn dry-season female. 
It is probable that the specimens of the dry season were 
coming to an end, and that one of the early wet forms could 
find no female of its own phase, and paired with one of the 
other phase, which was still abundant. The donor also sent 
valuable notes on the climate and seasons of Kilimanjaro, 
which will be of great use in the attempt to understand the 
phenomena presented by this extraordinary butterfly. These 
notes and some account of the specimens of Preczs sesamus 
are published in the Proc. Ent. Soc. Lond., 1906, pp. Iviii—-Ix. 
Slopes of the mountain (May, 1905): a set of 16 butterflies 
and 2 moths (6 catalogued). 
Western slopes of the mountain, Kibosa, about 5,000 ft. 
(Nov. 1, 1905): two fine ¢ Charaxes cithaeron and 1? Pla- 
nema gquadricolor. The latter, being in poor condition, is
