the exception of the neighbourhood of London, where a dark 
grey form is found, as shown in the series from Epping 
Forest. The Delamere Forest insects ranged from a rather 
light colour to a melanic form, with intermediates showing 
a complete gradation from one form to the other. The 
lighter insects were bred very sparingly from collected larve, 
from 10 to 11 per cent. of melanic forms agreeing more or 
less closely with the form robsoni, Collins, being obtained, 
the remainder, about 90 per cent., disclosing the dark grey 
form. In answer to a question by Mr. H. Rownanp-Brown, 
the exhibitor said that the undergrowth in Delamere Forest 
was chiefly bracken, and the surface of the ground covered 
with the decayed remains of this plant. Beneath this is sand, 
which occurs over a large area of the Forest, and also gravel, 
gravel-pits being somewhat extensively worked. The larve 
of A. nebulosa seemed fairly well distributed wherever young 
birches, whitethorn, or bramble occurred. 
A discussion followed relative to the appearance and increase 
of melanic forms in a restricted area like Delamere: Forest 
within the last fifteen or twenty years, in which Dr. T. A. 
CHapman, Mr. G. A. K. Marswati, Mr. J. W. Tutt, Mr. 
A. W. Bacot, Mr. W. G. SHELDON, and other Fellows 
joined. 
Rare CoLeoPpTeRA FROM THE ISLE or WiGuHtT, ETc.—Mr. 
R. 8. Mrirrorp exhibited two ¢ specimens of Cryptocephalus 
bipunctatus, taken by him at Niton in the Isle of Wight 
in July 1907, while sweeping the grass on the slopes of the 
Undercliff. He observed that the specimens were two forms 
of varieties which he understood were well known on the 
Continent, but that neither had ever been found in Britain 
before. No other specimen was met with, although the spot 
was well worked. The locality seemed to be a strange one 
for this beetle, as there were no hazel or birch trees in the 
neighbourhood. 
Mr. Mirrorp also showed Paracymus xneus, Germ., which he 
had obtained from Mr. Harwood of Colchester, who had believed 
these specimens to be P. nigroxneus. The examples shown 
were captured on the North Essex coast in June 1898, and 
there could be no doubt that P. xneus must be regarded as a
