hinder part : mandibles very long and toothed at the 
extremity ; palpi very long and slender, composed 
of long joints, the maxillary pair terminated by a fleshy 
wart, (not an acute spine, as stated by Mr. Grey ;) 
legs long, especially the hinder ones, the thighs of 
which are much thickened ; tibiro strongly spined ; 
tarsi four-jointed, but having a fleshy lobe at the base 
of the radical joint on the under side, by which cha- 
racter it is associated with the present family, and 
not with that of which we are next to speak.

abdomen conical and compressed, the female without 
projecting ovipositor. The males are without a 
circular spot at the base of the tegmina, and their 
stridulent note is therefore entirely produced by the 
friction of the thighs against the tegmina and wings. 
Such, concisely, are the most marked distinctive 
features of a tribe of insects which have long been 
objects of historical celebrity on account of their ex- 
tensive depredations. As they are very numerous, 
and present considerable differences in external cha- 
racters, the genera into which they are divided are 
necessarily many. The ravages of locusts have been 
often described, and the accounts given by travellers of 
their astonishing multitudes and powers of destruction 
are calculated to excite our astonishment. It is also
