notes with a discussion of the segmentation of the abdomen in lepi- 
doptera,” which is printed in extenso in this volume. 
March 18th, 1913.— Gynandromorphous Smerinthus populi. —Mr. 
L. W. Newman, a specimen bred from Bexley pupa, March, 1913, the 
gynandromorphism being complete, left side $ , right side ? . 
Nemeobius lucina. —Mr. Y. E. Shaw, a long series bred from ova 
collected from the leaves of primrose at Clandon, one specimen being 
a nice variety in which the two transverse rows of white spots were 
very minute. 
Camptogramma bilineata. —The species being under discussion this 
evening, the following members exhibited it:—Mr. S. J. Bell, speci¬ 
mens from Chalfont; Mr. J. Riches, specimens from North London; 
Mr. A. \V. Mera, specimens from various southern localities, those 
from Mucking, Essex, being the darkest, and probably referable to 
Gumpenberg’s infuscata. Dr. E. A. Cockayne, a great number from 
various localities. In those from the coast of Sutherland, many of 
the males showed a tendency to black spotting of the lines—five black 
spots, three on the outer and two on the inner line, and the upper 
wings are of a brown tint. In those from the Shetlands both upper 
and under wings were brown in striking contrast to the yellow race from 
the southern localities. 
Cidaria corylata and var. albo-crenata. —Dr. E. A. Cockayne, a 
series from Argyleshire, where he had found it plentiful. 
Discussion. — Dr. E. A. Cockayne opened a discussion on 
Cawptogramnia bilineata, specially confining his remarks to the fine 
exhibit he had brought. In Sutherlandshire he noticed the species in 
large numbers, where for preference they rested on rocks and in shady 
places, but very few being beaten from the hedges. He had met with 
it a good deal in Aberdeenshire, finding the males very ordinary, but 
the females variable in ground colour as well as in darkening of the 
band. The Forres specimens had distinctly brown forewings. The 
Shetlands produced a wholly brownish race, losing the rich yellow 
colour. On the whole he considered it a species which would repay 
the diligent worker. Mr. Sabine said that in his experience of two 
seasons in the Shetlands, it w T as scarce and local, and that he could 
corroborate Dr. Cockayne in its preference for rocks as resting places. 
April 1st, 1913.— South-Eastern Union of Scientific Societies. 
—Dr. E. A. Cockayne was appointed as the Society’s delegate to the 
1913 Conference at Hampstead. 
Bryophila muralis. —Dr. Cockayne, a long and variable series 
from Cork, some being almost identical in markings and size to B. par. 
Leucania extranea.— Mr. R. G. Todd, two specimens taken at 
sugar in Devonshire, August and September, 1912. 
Caluimorpha dominula var. rossica. —Mr. L. W. Newunan, living 
specimens just bred from pairings of the $ and of the variety. 
The larvae had been forced in a heat of 60° to 65° from January, and 
the pupal stage only lasted three w'eeks. 
Nyssia hispidaria.- —Mr. W. E. King, specimens from Epping 
Forest, some showing a melanic tendency.
