small variations in the pattern of Papilio dardanus. 661 
“Buddu, W. shore of the Lake ”—7 specimens; Toro— 
5 specimens; Unyoro—1 specimen; “neighbourhood of 
L. Wamala ’”—1 specimen; the Semliki valley—1 specimen. 
These 18 specimens, all collected by Mr. 8S. A. Neave, 
seem rather a heterogeneous lot, but the average size of the 
spot is practically the same as in the West Coast forms, viz. 
65°2 %. Individuals range.between 39°7 % and 86°9 %. 
From the northern shore of the lake in the neighbourhood 
of Entebbe, from the islands, and from the neighbourhood 
of Kisumu on the Eastern shore come altogether 85 speci- 
mens. From Entebbe Mr. C. A. Wiggins sent 55 specimens, 
and Mr. Sheffield Neave contributed 8, and 5 more from 
Kampala. There is a single specimen from the Mabira 
forest (Wiggins) and 8,—seven of them represented on 
Plate XX XIX—from Bugalla Island (G. D. H. Carpenter). 
From the neighbourhood of Kisumu on the E. shore of 
the lake come 7 specimens contributed by C. A. Wiggins 
and one by A. Vincent. These specimens are included 
with those from Entebbe rather than with the other speci- 
mens from EH. Africa which are of the subspecies tebullus, 
Kirby, and come from localities far removed from the 
E. shore of the lake. 
The average for these 85 specimens is not far from the 
West Coast average: but there is a greater range of 
variation, viz. from 38 % to 102 % (Plate XX XIX, fig. 9). 
Passing eastwards we come now to the locality of the sub- 
species tibullus, Kirby, and polytrophus, Jordan. These 
are represented by 11 hippocodn caught by K. St. A. Rogers 
near Mombasa, 2 by the same collector on the slopes of 
Kilimanjaro, 1 from Taveta by C. A. Wiggins, 4 from 
Kikuyu Escarpment by W. Doherty (these latter belong 
to the subspecies polytrophus), and a single specimen (Don- 
caster) from German East Africa. I have also included 
in this group, perhaps unjustifiably, a single specimen 
collected by S. A. Neave in Eastern Usoga, in the far E. 
of Uganda, whose spot-cell ratio was 78°2 °%. The average 
figure for these 20 specimens is 78 %, and they are a fairly 
uniform lot, all coming between 71:4 % and 90°5 %, with 
the exception of one at 62°5 %. 
There is another fine series of the subspecies tebullus 
collected by C. F. M. Swynnerton at Chirinda, Gazaland, 
S.E. Rhodesia. These 21 specimens have an average 
spot-cell ratio of 80 %, and are also a very compact group, 
ranging from 70°4 % to 91:2 %.
