A very fine and valuable collection of butterflies from Macao, 
S.E. China, were presented by J. C. Kershaw, Esq. Through 
Mr. Kershaw’s generosity the Department is rapidly acquiring 
a full and complete collection of butterflies from this most 
interesting part of the world. The data are precise and de- 
tailed, and the donation includes a long series of the species 
with profound seasonal changes, such as Precis almana and its 
entirely different wet form, asterie. Furthermore, the captures 
have, as far as possible, been effected right through the year ; 
so that the replacement of one form by the other and the 
amount of overlap can be studied in the only way in which 
sound conclusions can be reached, viz. by the investigation of 
a large mass of material, carefully collected and accompanied 
by the fullest data. There are also included specimens by 
means of which Mr. Kershaw has proved that the well-known 
Euploeine butterfly, Crastia godarti, is a form of C. amymone. 
In spite of the conspicuous differences between these insects, 
Mr. Kershaw shows that they are connected at Macao by 
a long series of transitional forms, and he has now even suc- 
ceeded in breeding one well-marked form from the other (Proc. 
Ent. Soc. Lond., 1904, p. 1xxxvi). 
Up to the present time 664 butterflies (the great majority 
captured in 1904), 1 moth, and 3 Coleoptera have been added 
to the Collection, together with 13 butterflies from Macao 
and 2 from Hong Kong, collected by the same naturalist, and 
presented by his brother, G. W. Kershaw, Esq. 
Two male specimens of Papilio laglaizet and 2 specimens 
of its model, the Uraniid moth, A/czdzs aurora, from Dutch 
New Guinea, were presented by the Zoological Museum, Tring. 
This is a most beautiful example of mimicry, new to the 
Bionomic Series. The colour of the under-side of the body 
of the moth is reproduced on the wings of the butterfly, 
tingeing the parts which probably cover the body of the mimic 
in the position of rest. 
A specimen of Papilio menestheus, from the Gold Coast, 
was also presented by the same Museum. 
A valuable little collection of 56 insects of various Orders,
