268 THE CANADIAN NATURALIST. 
Grylli with straight wings^ having long setaceous antennae, 
are generally called grasshoppers ; and those with short stout 
antennae, locusts ; those whose wings are flat on the back, 
and lap over each other, are called crickets. None of the 
species are usually seen in the perfect state much before this 
season : those which are met with, among the herbage, are 
in the earlier stages. This field locust is a clumsy, thick 
species, and its motions are rather heavy. It is extremely 
numerous in our grass fields, and probably the aggregated 
individuals in one field consume no small quantity of herb- 
age. In ploughing round a triangular piece of green sward, 
I have been amused, as I gradually drew near the end, to 
observe the hosts of these field locusts crowded together on 
the constantly diminishing little spot of grass in the centre. 
They would not stay on the furrow, but continually re- 
tired before the plough among the grass ; which, growing 
less and less at every furrow, caused the inhabitants of the 
whole field gradually to collect in this little oasis in the earthy 
desert, where they kicked, and sprawled, and leaped, like 
fishes in a net, until the inexorable ploughshare at length 
turned over their last fragment of turf, and obliged them to 
seek a new home. 
C. — On the road to Compton, I have noticed a large 
locust, with dusky elytra, and bright yellow wings with a 
black border ; it was very watchful, not permitting me to 
approach it, till after many trials and much manoeuvring. 
It flies short distances, and often remains stationary on the 
wing over a particular spot ; and while on the wing, makes 
a noise exactly like that of a watchman's rattle in minia- 
ture. 
F. — -I know it well, and call it the Rattling Locust. 
( (Edipoda Sulphurea ^ ) It is singular to observe the pre- 
dilection which some insects have for particular places. A 
spot on the road to the village, at the foot of a hill, a little
