bearing, where the conservation of foliage or fruit crops is of importance. I 
have myself witnessed that certain water beetles, namely Dytiscus margi- 
nalis and several species of Colymbetes, have dropped down on hothouse 
frames protected by glass. They made this mistake by taking the glass to 
be their native element; theirs was an error of sight. Assuming that 
insects injurious to fruit-trees often discern their positions by sight, it seems 
worth while to offer the suggestion that, the means which attracted the 
water beetles might possibly be made use of for keeping away such insects 
as avoid water, and which might possibly be scared away by any object 
simulating that element.”

Exhibitions, &c. 
Prof. Westwood exhibited living examples of Argas reflexus, from 
Canterbury Cathedral, of which he brought dried examples before the 
meeting on the 5th ultimo; also another species of the same genus collected 
by Dr. Livingstone in Central Africa, remarkable for the rounded tubercles 
with which its surface is studded. This latter species, according to Dr. 
Livingstone’s observations, enters the feet of the natives, between the toes, 
causing pain and inflammation. 
Mr. S. Stevens exhibited an apparently undescribed species of Phycita, 
taken near Gravesend, bearing much externalesemblance to certain species
