In the vicinity of Boston young examples of this species begin 
to appear in May, and adults in July (juv., — May 14, South 
Natick, Mass.; May 24, Dedham, Mass.; adult, — July 10, Sud- 
bury-, Mass.; July 23, Sher-

It is quite possible that a 
third species, A. davisi, will

THE CAVE-CRICKETS, CAMEL-CRICKETS, OR STONE-CRICKETS 
— CEUTHOPHILUS, ETC. 
These curious insects have received a variety of names refer- 
ring to their appearance or habits: Camel-crickets, because of 
their high, arched back; Cave-crickets and Stone-crickets from 
their habit of hiding themselves in caves and holes beneath stones, 
in hollow trees, and similar dark, moist places. 
They have relatively soft-walled, hump-backed bodies, lacking 
even the rudiments of tegmina and wings; extremely long and 
delicate antennae; and usually long but powerful hind legs and 
spiny tibiae with which they make prodigious leaps when dis- 
turbed. Their coloring is unobtrusive, chiefly of chestnut, choco- 
late-brown, or fuscous markings on a ground-color of pale yellow,
