FAUNA OF THE SOUTH.

covers. They feed on vegetable substances not only in 
their perfect state, but when they are grubs. In this list 
we place the spring beetles {Elater), several species ; Capri- 
corn beetles [Cramhicince) \ snout beetles (Curculiones), 
including the wheat weevil, rice weevil, and pea weevil ; 
and the leaf-eaters ( Chrysomilince). 
Order 2. Bugs. — Bugs do not generally undergo 
metamorphosis, like beetles. They come forth from their 
eggs in a perfect condition, with six legs and a proboscis, 
having no wings. The Cicadce form the only exception to 
this rule. 
In this order we may enumerate the squash bug 
( Coreus iristis), which sucks with its snout the sap of the 
squash and potato plants, and makes its winter quarters 
in the crevices of houses and under the bark of trees; 
tree-hoppers [Membracis), which feed on the leaves of the 
oak, thie hickory, the locust, and the poplar; plant lice 
(Aphis), infesting trees, bushes, and herbs; shield lice 
( Coccus), which suck the sap of fruit trees. 
Order 3. Straight-winged Insects. — We include among 
these the grasshopper, walking-leaves, crickets, cock- 
roaches, earwigs, soothsayers, Avalking-sticks, etc., all of 
which are found in great variety and abundance. 
Order 4. Butterflies and Moths are found in great va- 
riety. The useful silkworm can be raised with less care 
than in the North. We have seen the <Jecropia, the Poly- 
pheme, theZMwa, and the Promethea, forming their cocoons 
upon the leaves of our forest trees, as well as upon the 
trees of the orchards, inviting, as it were, the attention of 
man. We have the millers, the tent-caterpillars, the spaw- 
worm, the canker-worm, the apple-worm, all of which are 
more or k;ss injurious. We are troubled also with the 
bee-moth, the grain-worm, the carpet-moth, and the hawk-
