that it formerly enjoyed a much wider range than it does at the 
present day; but my idea is that in favourable seasons it is 
continually extending its range, whereas when the climatic or 
other conditions are adverse it is confined very much to head- 
quarters. Here, it is principally found in one or two places 
where holly is plentiful, and some seasons a specimen is rarely 
seen elsewhere; but at other times it is to be met with in 
gardens and lanes throughout the district, and even in the 
streets of the town; and Dr. Bree has drawn my attention to its 
periodical abundance about the ivy which grows upon Colchester 
Castle. Mr. Harcourt Bath’s own remarks seem to bear out this 
view, for he says, “‘ When the butterfly is very abundant it occurs 
all over the park, and sometimes even in the outskirts, though 
at other times it occurs only in two or three localities;” and it 
seems reasonable to conclude that what is happening at Sutton 
Park and here is also taking place in every county in which the 
species occurs.—W. H. Harwoop; Colchester, March 1, 1886. 
Lycmna arciotus.—This butterfly is of regular and tolerably 
common occurrence in this neighbourhood, where there are few 
hollies, but ivy is plentiful in the hedgerows. As far as my 
Xperience goes there are invariably two broods in the season: 
the first, late in April or beginning of May, nine-tenths of which 
are males; the second, in August, sometimes lasting into 
September, and it was once seen during the first few days of 
October ; I forget the year, but well recollect the circumstance. 
This latter brood seems to consist principally of females. I have 
noticed also that this little butterfly seems much attached to 
a place. There is a small shrubbery at the side of my late 
residence, containing, amongst other trees and shrubs, laurustinus 
and candleberry myrtles, but not any hollies. When the species 
was out, although perhaps none might be seen about on the 
wing at the time, I could yet, in suitable weather, always make 
sure of taking them at this particular spot, and have been 
accustomed to sit down and wait for them, as one does for 
Apatura iris. I took as many as seventeen in an hour one 
morning in this way, several of them off one particular sprig of 
flowers of the candleberry myrtle, on which shrub, as well as on 
the laurustinus, they were very fond of settling. May not the 
larve possibly feed on either or both of these?—EH. Sasrnz;
