printed and added to the specimens. The collection contains 
approximately the following numbers of specimens from the 
various localities visited:—Jamaica, 1,200; Barbados, 62; 
Trinidad, 215; Tobago, 225; Venezuela, 744; Colombia, 
112; Panama, 140; total, 2,698. The numbers are in reality 
ereater, because several specimens, when mounted on a single 
card, are counted as one. 
Two interesting families, bred from mimetic female forms of 
Papilio dardanus, subsp. cenea, were purchased from Mr. G, F. 
Leigh, of Durban. In the first of these the parent, of the 
cenea form, mimicking Amauris echeria and albimaculata, 
was captured Jan. 14, 1907, and laid 42 eggs, Jan. 15 and 16. 
From these, 32 butterflies were successfully reared, and in- 
cluded 15 males (non-mimetic), 16 females of the cezea form 
resembling the female parent, and a single female of the form 
hippocoon, mimicking the very different Asmauris, A. niavius 
subsp. dominicanus. The second family, bred, about the same 
time from a /ippocoon female (the parent, with its data, was 
inadvertently retained by Mr. Leigh, who has promised to 
send it at a later date), consists of 29 butterflies, made up of 
16 males and 13 females, all of the cezea form, and not one 
resembling the parent. The great interest of these families is 
the evidence afforded of the selective power of the model over 
the proportions of the mimetic forms of the mimic. The 
dominant Danaine pattern of Natal is that exhibited by 
Amauris echeria and A. albimaculata, and the corresponding 
mimetic female of P. dardanus is equally dominant. Further 
to the north, where Amauris niavius, subsp. dominicanus, 
predominates over, and in many areas altogether displaces, 
echeria and albimaculata, the corresponding “Azppocoon female 
of dardanus predominates over and finally displaces the 
cenea form, 
ADDITIONS TO THE BRITISH COLLECTIONS IN 1907. 
Mr. W. Holland’s Carabidae, chiefly presented to the 
Department in 1901, but also increased in subsequent years, 
constitute by far the largest part of this section of the British 
beetles. Nearly all the British Carabidae have now been
