scaled. If however a wedge of the wing be cut out witha 
pair of sharp scissors, the resulting edge of the wing showed 
hardly a trace of any overlapping scales, the scales them- 
selves being actually sheared. 
Several species of butterflies from British Guiana were also 
shown with injuries to the wings in the region, of the abdo- 
men. These included Heliconius burneyi ee we Stalachtis 
phedusa, Bia actorion and Methona confusa, the last-named 
being a most conspicuous injury just above where the abdomen 
is held when at rest. Such injuries to Danaine butterflies 
were quite rare. 
Locusts AND THEIR Foop.—The PrestpEen? exhibited photo- 
graphs of a large locust (Catacanthacris rubella) from the 
Congo Free State, which was captured holding a small mouse 
(Leggada %) with its front and middle legs, and was apparently 
devouring it. He read the following note from the Rev. M. 
H. Reid, who found it. ‘‘I never knew that a grasshopper 
would eat flesh, but seeing was to believe. I went to see 
several of the chiefs . . . during that time great swarms of 
locusts devoured every green thing. While looking at the 
locusts crawling over the native huts I observed the one I 
gave you. It held a mouse firmly, and had actually fastened 
its legs about the mouse so that there was no way of escape. 
. . . Some of the locusts had great spiders and others great 
roaches (cockroaches), and in fact anything which would make 
food.” ‘The specimen is now in the Natural History Museum. 
A discussion followed on the carnivorous habit of the 
Acridiidx, it being considered a very unusual phenomenon. 
The Rev. F. D. Moricz mentioned an occasion on which he 
had found wearing apparel devoured by grasshoppers in 
Switzerland, and other Fellows followed. 
ReEorprocaL CoNVERGENCE IN Limenitis.—Professor Poutron 
exhibited 7 males and 4 females of Limenitis (Basilarchia) 
lorguint from Vancouver’s Island; 11 males and 1 female 
from British Columbia; 4 males from California; also 4 
examples of the Californian form of Adelpha bredowt, together 
with 5 specimens of the same species from Mexico and | from 
Guatemala. He also exhibited 2 males of the species which 
probably represents the ancestor of lorquini, viz. Limenitis
