on the hind wings ; it is similar on both surfaces of the 
wings. This specimen was also bred by Doubleday in 1842, 
in liis garden at Epping. Another male in his collection 
has some additional black spots adjoining the transverse 
series in the fore wing. In the Dale collection is an almost 
entirely black female. Specimens have been recorded having 
the normal ground colour replaced by whitish, similar in 
colouring to the white aberration of the Small Copper, ab. alba . 
It may be of interest generally to allude to the probable 
number of British L. dispar existing in collections. In the 
Lancashire Naturalist, November, 1910, Mr. J. R. Charnley 
published an interesting paper, " An attempt to enumerate 
the British Chrysophanus (Lycaena) dispar” stating: " The 
total number of specimens recorded is 936, of which 574 are 
males and 362 females. Of these only 165 have data ; 128 
being from Whittlesea Mere, 16 from Yaxley Fen, 12 from 
Holm Fen, 8 from Bardolph Fen." 
There are, undoubtedly, several examples in private col¬ 
lections, which for various reasons Mr, Charnley was unable 
to enumerate. It is probable, therefore, that the total number 
of British L. dispar existing at the present time is somewhere 
in the region of one thousand specimens.

Haunts and Distribution. The flight of this active little 
butterfly is short but rapid. It is fond of settling on the 
foliage of Bramble, Furze, Hawthorn, and other bushes, and 
suddenly darting off for a short flight around the branches 
and back again to another leaf. When at rest with closed 
wings on a leaf, it is very inconspicous owing to its green 
under surface. 
It frequents a variety of situations, the openings and 
borders of woods, flowery banks, rough hillsides, chalk downs,
