OF THE ANNULOSA. 373 



Having now obtained a general notion of the Mandi- 

 bidata, our thoughts ought to be employed on the best 

 method of quitting them. For this purpose we must be 

 guided by the excellent observations of Mr. Kirby, with 

 respect to the similarity of the organs of nianducation in the 

 Trichoptera, or Mouches PapilloJiacees of certain writers, 

 and the Lepidoptera ; those of Baron Degeer as to the cor- 

 respondence between the forms of their wings, and be- 

 tween the internal organizations of their larvse ; and finally 

 by those of Reaumur as to the affinity visible in the gene- 

 ral appearance of the insects themselves. In this manner 

 we shall enter among the 



Haustellata, 

 or Insectes Suceurs of M. Cuvier. In all his various works 

 M. Latreille assigns a place to the Lepidoptera immedi- 

 ately after Hymenopterous insects, and immediately be- 

 fore the Diptera. He has thus differed entirely from 

 Linnaeus, with whom the Lepidopterous insects are situated 

 between his orders of Hemiptera and Neitroptera. If, 

 however, it be asked what direct affinity the French 

 entomologist was able to detect between a butterfly and 

 the Hymenopteru, or what direct affinity, on the other 

 hand, Linnaeus could have detected between it and the 

 LibellulcB (the insects which he places nearest to the Lepi- 

 doptera), I fear that the patience of the inquirer will be ex- 

 hausted long ere he can obtain any satisfactory answer. 

 The maxilla indeed of certain Hymenopterous insects form 

 a proboscis or trunk, having some similarity to that oi Lepi- 

 doptera; but this solitary character might with equal pro- 

 priety be used to connect the latter order with certain Coleo- 

 ptefa, as the genera Nemognatha and Gnathium. Upon the 

 whole, therefore, the celebrated Swede has the advantage
