LEPIDOPTERA. 



The station of this order in the sub-kingdom of Annulosa, is clearly indicated in 

 the Horae Entomologicae. The Lepidoptera are here arranged in the class of 

 Haustellata, between the orders of Diptera and Homoptera. In the diagram which 

 exhibits a view of the classes of the Annulosa, they meet the order of Trichoptera, 

 and thus form a connexion between the classes of Haustellata and Mandibulata. 

 See Hor. Ent. p. 390. The relation of the Lepidoptera to the Homoptera is more 

 particularly pointed out in page 375 of the same work ; and that to the Diptera, in 

 page 379. I therefore refer the reader, for a more detailed exposition of Mr. 

 Macleay's views of the natural situation of this order, to the pages cited ; where the 

 analogy of the Lepidoptera to the other orders of Annulosa is likewise pointed out, 

 in a tabular view ; see page 392. 



The Lepidoptera are chiefly distinguished from the other orders of Annulosa, by 

 their mouth, wings, and metamorphosis. The acute observations ofM. Savigny show 

 that the mouth is provided with lips, mandibles, and maxillae. The latter by their 

 union form the proboscis, and are thus described : mandibles, at their base, intimately 

 united with the lower lip, elongated, canaliculated, forming together by the union of their 

 plates, a tubular spirally-convoluted proboscis, which is concealed by the palpi. The 

 mandibles are very minute, distant, slightly or not at all moveable, and unfit for masti- 

 cation. There are four palpi, of which two are maxillary and two inserted at the base
