College, for insects from the Faroe Islands; W. J. Lucas, 
Esq., B.A., for insects from various localities ; Champion B. 
Russell, Esq., M.A., University College, for butterflies exhibit- 
ing injuries probably caused by the attacks of enemies; J. A. 
Finzi, Esq., for a valuable series of Swiss Lepidoptera with 
precise data; Dr. G. B. Longstaff, D.M., New College, for 
Indian Lepidoptera with precise and valuable data (nearly all 
the specimens arrived in the present year); Miss Dorothy 
M. A. Bate, for a very valuable set of insects from Cyprus ; 
and C. B. Taylor, Esq., F.E.S., for a very fine and interesting 
series of insects of many Orders from Jamaica. The Professor 
also presented a few insects from Fontainebleau. 
Special mention must be made of Monsieur Charles Ober- 
thiir’s generous gift of rare examples of mimetic Lepidoptera 
from South-western China and adjacent countries. These 
deeply interesting accessions arrived in part at the end of 
1903, in part at the beginning of the present year. The phe- 
nomena of mimicry in the great northern land-belt as affected 
by the invasion of forms from the tropics presents a most 
fascinating problem for investigation, and Monsieur Oberthiir’s 
great kindness has furnished the Department with the material 
for attacking it. A full account of this invaluable gift will be 
furnished in the next Report, when the specimens will have 
been catalogued. 
Just at the end of the year a deeply interesting accession 
arrived from Natal, presented by George F. Leigh, Esq., F.E.S. 
The gift consisted of a series of specimens of Papilio dardanus 
(=cenea) bred from the eggs ofa single female. Both parents 
were included in the consignment. The various different forms 
of female are the most wonderful examples of mimicry as yet 
known, and this is the first occasion upon which their specific 
jdentity has been proved by breeding.
