106 STATES OF INSECTS. (Larva.) 
ters of the first of these divisions: the second, which is 
by far the most numerous, will be afterwards considered. 
I. The frst division includes the larvae of Scorpions, 
Spiders, Cockroaches, Grasshoppers, Lanthorn-flies, Bugs, 
&c.; or generally, with the exception of the Flea and 
Crustacea, the whole of the Linnean Orders Aptera and 
Hemiptera. All these larvze, however remotely allied in 
other respects, agree in the general similarity which they 
bear to the perfect insects which proceed from them. 
The most acute entomologist, untaught by experience, 
could not even guess what would be the form of the 
perfect insects to be produced from larvee of the second 
division, while they can recognise the form of the spider, 
the cricket, the cockroach, the bug, and the frog-hopper, 
in that of the larvae. There are, however, differences in 
the degrees of this resemblance, according to which we 
may, perhaps, divide this tribe in their second state as 
follows :— 
i, Those that resemble the perfect insect, except in 
the relative proportions and number of some 
of their parts, 
ii. ‘Those which resemble the perfect insect, except 
that they are apterous, or not yet furnished 
with organs of flight. 
i. Spiders, Phalangia, scorpions, lice, Podure, sugar- 
lice (Lepisma), mites, centipedes, millepedes, &c. come 
under the jist subdivision. The larvee of the first six 
tribes here mentioned differ at their birth from the per- 
fect insect, only in size and the proportions of their parts. 
Thus the larvee of spiders have their legs of a different
