OF THE ANNULOSA. 399 



of feet shall be here increased above the usual number in 

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

 maxim of the Philosophia Entomologica, " Ubiplures quam 

 sex pedes adsunt, auteriores sive pectorales tantum veri 

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

 treille, in describing the Hymenoptera, says " Leurs larves 

 ressemblent a uri ver^ et sont depourvus ch 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 

 larva? 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 larva? of the Mandibulata 

 .■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 larva? of Ortho- 

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

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

 ral resemblance to the Gryllida, we have the larva? of 

 Mantes and even of Phyllia represented most closely by- 

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

 stinct among the Ametabola, it would appear that Na- 

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

 produced in the next circle and in their proper analogical
