Dark Synopsia abruptaria. —Mr. T. H. Hamling, Synopsia abrup- 
taria of a rich brown colour, obtained from inbreeding. Mr. A. W. 
Mera also exhibited some dark forms of this species and some also 
rather paler than normal. 
Variation op Plebeius ®gon.— Mr. G. H. Heath, a series of 25 5 
PUbeius aer/on, all of which were different. They had been caught 
without any special picking at Eynsford, Kent, and were remarkable 
for their large size and blue tinting, some being referable to the ab. 
Corsica. 
Lepidoptera from Argentina.— Mr. L. B. Prout, a miscellaneous 
box of insects just received from Mr. A.. F. Bayne, in the Argentine. 
PoLYOMMATUS BEELARGUS PROM FOLKESTONE.- Mr. W. J. Kaye, a 
series of Polyommatus bellaryus from Folkestone, "with one $ particu¬ 
larly well shot with blue. Mr. C. P. Pickett also showed P. bellaryus 
from the same locality. 
Plusia moneta from several localities.— Mr. Pickett further 
showed a long series of Plusia moneta from Clandon (Surrey) and 
Bexley (Kent). The former were markedly lighter in colour. Dr. 
Chapman, in speaking on this series from Clandon, said that if all the 
larvae came off one plant, the locality need not have exerted any 
influence on the species, and was not the prime cause of variation. 
Mr. T. H. L. Grosvenor, a series of P. moneta from Redhill. 
New Zealand exhibits.— Mr. Ambrose Quail, a series of the New 
Zealand Tortricid Epalxiphora axenana, no two of which were alike, 
so extreme was the variation. AFo a remarkable instance of a 
predatory Pompilid fly Salius monarc,lius, which successfully attacks 
the spider Pyrrhotele antipodiana. Mr. A. Bacot, in commenting on 
this exhibit, said it did not matter whether the fly killed the spider or 
not, as the larvae of the former could live and thrive on decomposing 
animal matter. 
Homceochromatic butterflies from S. France.— Dr. Chapman, 
the three butterflies Satyrus dry as, Coenonympha oedipus, Heteropterus 
morpheas, all of which were noticeably alike in colouring, and which 
were stated to have been found together in a small swamp at Guetary, 
S. France, other species not being in evidence at the time. It was 
suggested that here was possibly an association formed under stress. 
Notes from the Argentine.— -Mr. A. F. Bayne communicated, 
through Mr. L. B. Prout, a short paper on the “Physical features of 
the Argentine.” A vote of thanks to Mr. Bayne was proposed by Mr. 
S. J. Bell, seconded by Mr. J. A. Clark, and passed by all present. 
Oct. 20th, 1903.— Exhibition and Discussion on Plusia moneta. 
—A.large number of members exhibited specimens of Plusia moneta 
to illustrate the discussion held. Mr. Pickett, specimens and cocoons 
of P. moneta. Dr. Chapman called attention to the black patch of the 
pupa, and thought that that part was stouter and more like an ordinary 
noctuid pupa case than the other transparent portion. Mr. V. Eric 
Shaw, a very remarkable aberration of P. moneta, which had the whole 
of the wings suffused with rich brown with only the uniform stigmata 
left golden. The forewings were narrower and more pointed than in 
normal specimens. Mr. A. W. Mera, a fine set of Plusias, including 
P. bractea and P. moneta, the former were from Enniskillen and Kin- 
kardineshire. Dr. Sequeira, Mr. A. Bacot, and Mr. S. J. Bell all
