ADDITIONS TO THE COLLECTIONS IN 1Igo5. 
A very fine and interesting series of butterflies from the 
following localities in the British East African Protectorate 
and in the adjacent German territory to the south, were 
presented by the captor, the Rev. K. St. Aubyn Rogers, 
M.A., Wadham College :— 
Mombasa (1904-5): 115 specimens, of which 66 are cata- 
logued, and many others added to the collection. The species 
include Neptidopsis fulgurata, Acraea crystallina, and Hypoly- 
caena pachalica, all greatly wanted. <A bred set of elenois 
severina is also of great interest in estimating the amount of 
variability within the limits of a single family. 
Taveta, about 2,500 ft. (1905): 647 specimens (including 
three moths), of which 311 are catalogued and many others 
added. The collection includes a fine representative series of 
butterflies from this most interesting locality, Four specimens, 
exhibiting injuries probably inflicted by enemies, have been 
added to the bionomic series. A Lycaenid butterfly, Pentila 
amenaida, and Geometrid moth, Petovia dichroaria, captured 
on the same day, Dec. 9, 1905, have been placed in the 
mimicry collection. They are described by the donor as 
closely resembling each other on the wing. The case is of 
special interest, inasmuch as this same species of moth was 
found by Mr. Guy Marshall in Natal, flying with and closely 
resembling on the wing a Lycaenid of a different genus— 
Alaena amazoula (Trans. Ent. Soc. Lond., 1902, pp. 497-8). 
It is probable that the resemblance is Miillerian (synapo- 
sematic) in both cases. 
Taita, 3,000 ft., and Dabida, 3,500 ft. about 100 miles 
N.W. of Mombasa (May, June, 1905): a set of 13 butterflies 
(2 catalogued). 
Forest near Pangani River, Kitovu, S.W. of Taveta (Dec., 
1905): seven butterflies, of which the 4 catalogued include 
a pair of Lachnoptera ayresit. 
Maketan, about 3,800 ft., between Burra and Taveta (May, 
1905): eleven butterflies, of which Acraea chilo is the only 
one catalogued.
