there was certainly no marked difference, and the ova were similar. 
Commenting on the material exhibited, Mr. Nicholson said that there 
did not seem to be a single character in the imago sufficiently con¬ 
stant, as far as he could see, to infallibly differentiate quercus from 
callunae, or callunae from spartii, although, generally speaking, the 
two latter seemed, on the whole, darker than quercus, and more 
closely allied to each other than to it. It seemed to him that the 
three so-called species were, in all probability, simply local or racial 
varieties of one species, and Mr. Tutt’s remarks would appear to con¬ 
firm or, at any rate, strengthen this view. Mr. Prout stated that he 
had found a female callunae (?) drying its wings on a plant of heather 
(Calluna ), at the end of July, 1894, near Lyndhurst. Mr. Horne (of 
Aberdeen) sent for exhibition a representative series of Aberdeenshire 
callunae, consisting of eight males and ten females. Two of the males 
were of a dark buff colour, with the usual markings rather darker 
buff. These were justly admired. Mr. Bayne asked if anyone 
knew whether there was any form corresponding to callunae found 
in mountainous localities on the Continent. Mr. Warburg said 
he thought Milliere would have described it, if such a form 
existed. Mr. Tutt, however, stated most distinctly that B. callunae 
occurred in the mountainous districts of Southern Europe. He 
said that he captured a larva in August, 1894, on Mont de 
la Saxe (above Courmayeur), that it spun in due course the 
following month, and produced a fine typical female callunae the 
following summer. Mr. Bacot exhibited specimens, and read the 
following notes :—“ 2 ^s. Pupae received from Aberdeen Nov. 1894, 
emerged June, 1895, as typical callunae. 2 2 s. Larvae taken on 
Exmoor, Aug., 1890, hybernated as pupae and emerged May, 1891, 
one a cripple, the other a pale callunae form. 1 $ . Taken on Lundy 
Isle, Devon, Aug., 1887 (typical quercus). lj. Larva taken at 
Folkestone, Aug., 1891, hybernated as pupa and emerged the following 
year, in 1892 (? June), as typical quercus. 1 $ . Taken at Lyme, 
Dorset, July, 1893 = typical callunae upper side, tends rather to quercus 
coloration underneath. 1 $ . Larva received from St. Anne’s-on-Sea 
in May, 1892 ; emerged same year, and resembles the last. 1 $ , 2 J s. 
Larvte taken in Essex, May, 1894, emerged July, 1894, as typical 
quercus. The basal patch is probably a remnant of the inner or basal 
band, B. trifolii, representing a transition form between callunae and 
B. rubi. It (the basal patch) appears to be present in nearly the 
whole of the callunae exhibited, and is absent in all the quercus, save 
one specimen, exhibited by Mr. Prout, from Southend, and others from 
St. Anne’s-on-Sea; none of Mr. Warburg’s South of France quercris 
and spartii showing the slightest trace of this marking.” Mr. 
Garland exhibited two female Bornby.v quercus, bred from pup* found 
at Eastbourne; one of them was nearly colourless in the hind- 
wings, but somewhat crippled ; also two female Polyommatus icarus, 
in one specimen taken at Riddlesdown, 1896, the wings were of a 
brighter blue than usual ; the other taken at High Beach, 1896, 
having the fore-wings splashed with streaks of white and of a bright 
blue colour.
