Hemiptera-Heteroptera made by himself in the island of 
Corsica in May and June last. 
The Rey. Theodore Wood exhibited a variety of Saturnia 
carpini, with semi-transparent wings, a large proportion of 
the scales being apparently absent, bred with several examples 
of the type-form at Baldock, Herts; also a pale variety of 
Smerinthus populi, which was said to have been bred, with 
several similar specimens, from larve marked with rows of 
red spots on both sides. 
Mr. R. South exhibited a variety of Argynnis aglaia, 
approaching the form known as var. charlotta, and a variety 
of EHuchelia jacobee, in which the crimson costal streak 
was continued along the outer margin almost to the inner 
margin, taken by Mr. Fowler at Ringwood, Hants, in 1893 ; 
a variety of Argynnis euphrosyne, taken by Mr. Mead in 
Epping Forest, in 1898; and a series of black and other 
forms of Phigalia pedaria, bred during the present year 
from a black female captured last spring by Mr. Rose, of 
Barnsley. 
Mr. South also exhibited, on behalf of Dr. H. G. Knaggs, 
working models of the mechanical decoy and spring net 
described by the inventor in the Entomologist xxvi., pp. 154 
—157, 180—182, 207—210. He remarked that, although 
the apparatus might appear somewhat complicated in 
character, it would be found on examination to be really 
simple in construction. It could be quickly fixed up for use, 
readily taken apart again, and when packed the whole of the 
spring net could be stowed away in a bag measuring only 
twenty-six inches in length, and cight and a half inches in 
eirth, 
So far the contrivance had not been tested in the field, but 
on one occasion Dr. Knagegs had fitted it up on his lawn in 
Camden Road, and caught a specimen of Pieris brassica. It 
would probably be found of the greatest use to collectors of 
Lepidoptera in tropical countries. If specimens of a desired 
species were attracted by the decoy within the area com- 
manded by the net their capture would be certain, as the 
action of the springs was so rapid that the fastest flying 
butterfly would have little chance of escape.
