ORTHOPTERA. 
II. GRASPERS. ( Orthoptera raptoria.) 
These, which consist of the Mantes , called praying mantes 
and soothsayers, from their singular attitudes and motions, 
and camel-crickets, from the great length of the neck, are 
chiefly tropical insects, though some of them are occasionally 
found in this country. Moreover, they are exclusively pre- 
daceous insects, seizing, with their singular fore legs, cater- 
pillars, and other weaker insects, which they devour. 1 hey 
are, therefore, to be enumerated among the insects that ate 
beneficial to mankind, by keeping in check those that subsist 
on vegetable food. 
III. WALKERS. ( Orthoptera ambulatoria. ) 
To this division belong various insects, mostly found in 
warm climates, and displaying the most extraordinary forms. 
Some of them are furnished with wings, which, by their 
shape, and the branching veins with which they are covered, 
exactly represent leaves, either green, or dry and withered ; 
such are the walking-leaves, as they are called ( Pliylliam 
pulchrifolium, siccifolium, &c.). Others are wingless, of a 
long and cylindrical shape, resembling a stick with the baik 
on it, while the slender legs, standing out on each side, give 
to these insects almost precisely the appearance of a little 
branching twig, whence is derived the name of walking-sticks, 
generally applied to them. The South American Bacterid 
arumatia , rubispinosa , and phyllina , and two species of Bia- 
pheromera ? 1 described and figured in Say s “ American 
Entomology,” under the names of Spectrum fewiorattim (big. 
67, male) and biuittatum, are of the latter description. These 
insects are very sluggish and inactive, are found among trees 
[ i Two species of Phasma are noticed. The first is Bacunculus femoratus, Say, 
which lias also received the name of Bacunculus Sayi, Harm., and under which 
name it is best known to European authors. The latter was long ago figured by 
Stoll, in his great work upon the Orthoptera, and his name preoccupied that of 
Say and should be retained for it; it is Amisomorpha Buprestoules. The former 
lias been found in most of the States east of the Mississippi, while the totter is 
peculiar to Florida and some of the Southern States. — Um.icu ]
