106 STATES OF INSECTS. 



I shall begin by calling your attention to the charac- 

 ters of the fast of these divisions : the second, which is 

 by far the most numerous, will be afterwards considered. 



I. The first division includes the larvae of Scorpions, 

 Spiders, Cockroaches, Grasshoppers, Lanthorn-jlies, Bugs, 

 &c. ; or generally, with the exception of the Flea and 

 Crustacea, the whole of the Linnean Orders Aptera and 

 Hemiptera. All these larvae, 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 larvae 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, Podura, sugar- 

 lice (Lepisma), mites, centipedes, millepedes, &c. come 

 under thefirst subdivision. The larvae 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.
