it not too mucli to say, that if C. edusa could be made to settle down in 
this country, the species would follow the example of G. rhamni, and 
pass into hybernation early in the autumn, re-appear in spring, pair and 
produce the imago during late July, August, and (perhaps in the north) 
September, thus being confined, as in the case of G. rhamni, to a single 
brood. In reply to Dr. Buckell and others, Mr. Hawes stated that he 
understood from Mr. Tutt, that the great home of the species in Europe 
appeared to be among the mountains of Switzerland, at a low level, and 
that the area of the periodic immigrations, therefore included the ad¬ 
jacent lower-lying parts of France, Belgium and Holland, as well as 
Great Britain; in its native region, the species is understood to hyber- 
nate regularly, much in the same way as G. rhamni does in England. 
Replying to a further question, Mr. Hawes gave it as his opinion 
that C. hyale visited this country in the early summer months of this 
year (1892), similarly to C. edusa, though usually in fewer numbers, 
and spread over a more limited, i.e., south-easterly area. Mr. Tutt 
stated that edusa appeared to be a native of the Swiss Alps, 
and there it generally seemed to produce a single brood, the imagines 
being driven into hybernation soon after their emergence by the cold 
weather. From this centre it occasionally migrated to various parts of 
the Continent, including Britain, and then tried to produce a second 
brood in the late autumn, failing to do this it became exterminated. 
He expressed his opinion that if the English winter were to set m 
shortly after the emergence of the August brood, they would hybemate 
at once, and the species would be common the following year. The 
proceedings concluded with a vote of thanks to Mr. Battley for opening 
the discussion. 
Tuesday, 3rd January, 1893.—The Society held its annual Pocket- 
box Exhibition, and several interesting exhibits were made. Among 
others, Mr. Clark exhibited two varieties of Argynnis selene, one with 
the upper side dusted witli black scales, the other having the black 
markings coalescing into a central band; a specimen of A. euphrosyne 
with a pale (xanthic) hind wing; and a small darkly suffused specimen 
of Saturnia carpini. Mr. Bloomfield, a bred series of Papdio rnachaon, 
one specimen having a red inner margin to the black band on the hind 
wings ; a series of Colias edusa , including a female without the yellow 
spots in the marginal band; also spring and summer specimens of 
Selenia iUunaria. Mr. Battlev, a variable series of the undersides of 
Epinephele hyperanthus from Caterham and Xortli Devon. He pointed 
out that the lower spot on the upper wing was frequently absent, and 
that in no case were the two sides exactlv similar in marking's. Mr. 
Jackson, Stauropus fagi, JSIacroglossa bombyliforrnis, Cyrnatophora ridens, 
Cuspidia aim and Ephyra ornicronaria, all taken in the Xew Forest last 
May ; also a specimen of Polyommatus phlceas from Walthamstow, with¬ 
out the band on the hind wings, but with red streaks on the wing rays. 
Mr. Tremayne, a number of species from the Xew Forest, including 
Argynnis paphia var. valezina, Stauropus fagi and Xola strigula, the 
latter being taken on sugar. Captain Thompson, a small dark specimen 
of Tephrosia biundularia from Stafford, Ptilodontis palpina from Halifax, 
and Hepialus sylvinus from Hampstead Heath. Mr. Xicholson, Cheirna- 
tobia boreata, and some strongly marked specimens of C. brurnata, from 
W est Wickham : also Leucania phragmitidis, taken some years ago near
