houses, where it frequents the kitchens, pantries, cupboards, and 
even the bedrooms. It is also found in some of the kitchens of 
houses on the high land. Out of doors too it occurs, generally 
under loose stones, and I have even found it amongst the rocks 
in the neighbourhood of Lot, more than a mile away from any house. 
Mr. Walker states that it also inhabits the West Indies, South 
America, and some of the eastern isles.

Hopper, which is found in houses. It occurs also in Europe, Africa, 
and Asia. 
G. capensis, Fabr. Ent. Syst. ii. 31 (Acheta). the veiy 
common large Field Cricket of St. Helena, where it is found abun- 
dantly in the hay-fields and grass lands of the higher parts, as well 
as under rocks and stones on the lower and warmer portions of the 
Island. It is one of the most familiar insects of the place, due, 
perhaps, to its cheerful chirp, which is heard during almost e\eiy 
evening, and sometimes through the daytime, in the woods and 
fields. It is an inhabitant of most parts oi the world.
