OF THE ANNULOSA. 399 



of feet sliall be here increased above the usual number in 

 a Winged insect; in which case we must bear in mind a 

 maxim of the Philosophia Eutomologica, " Ubiplures quam 

 sex pedes adsunt, anteriores sive pectorules tantum veri 

 pedes, reliqui omiies spurii et mutici." Finally, M. La- 

 treille, in describing the /:^??2e«q/?if era, says " Leitrs larves, 

 ressemh/eut a nn ver, et sont depoiwviis de pattes." 



But if the entomological reader can divest himself of 

 the notion of absolute divisions, and if he will recollect 

 the great difference there is between a tendency towards 

 any construction and the actually attaining it, I would re- 

 commend, in preference to being guided implicitly by such 

 examples, his studying the figures and descriptions of 

 larvae given in the works of Reaumur and Degeer, and 

 then judging for himself. 



Relations of analogy, however, are not rigorously con-, 

 fined to contiguous circles, but may sometimes be carried 

 on to the corresponding points of others widely distant. 

 Thus, on referring to the table of analogies, a comparison 

 may be instituted between the larvee of the Mandihiilata 

 and the corresponding orders of Crustacea, though we 

 must expect that the force of the resemblance should be 

 here much weakened by the intervening distance. Never- 

 theless, between the Amphipoda and the larvee of OrtJiO'- 

 ptera it is particularly striking; for, if we take no account 

 of the leaping Talilrus Locnsta, which bears such a gene- 

 ral resemblance to the Gryllidce, we have the larvae of 

 Mantes and even of Phyllia represented most closely by 

 some of these Crustacea. Such forms being far from di-r 

 ■stinct among the Ametahola, it would appear that Na-» 

 ture was resolved that they should not be lost, but be re- 

 produced in the ne?-t circle and in their proper analogical
