INTEODUCTOKT EEMAEKS. 11 



thinking of their larvce, I discovered that each of my groups, as 

 far as my knowledge of them went, had a peculiar character,'' — 

 which he then briefly describes on p. 422. 



Referring to the detailed description of the larvae of Coleopterous 

 Insects which he has detected, and arranged in five groups, it is 

 sufficient for my present purpose to state, that the first group, 

 examples of which are Carabus and Dytiscus, are represented 

 analogically by the Chilopodiform Ametabola ; the second type, of 

 which Scarabaeus is an example, is represented analogically by the 

 Chilognathiform Ametabola. The third type, of which Curculio 

 and Cerambyx are examples, is represented analogically by the 

 Vermiform Ametabola. ^\yQ fourth type, of which Coccinella and 

 Chrysomela are examples, is represented analogically by the Ano- 

 pluriform Ametabola ; and the _^M type, an example of which is 

 Meloe, is represented by the Thysanuriform Ametabola.* 



To guard against any misapprehension of the characters of the 

 relations here pointed out, Mr. Macleay gives the following caution 

 (see H. E. p. 423) : " The distinction, however, between affinity 

 and analogy, is perhaps nowhere in Entomology more necessary to 

 be attended to than here ; since, in terming larvre Chilognathiformes 

 or Chilopodiformes, it is not meant that they are Scolopendra^ or 

 Jidi, or even near to them in affinity, but only that they are so 

 constructed that certain analogical circumstances attending them 

 strongly remind us of these Ametabola." 



Considering, therefore, the determination to which Mr. Macleay 

 has arrived regarding the primary groups of Coleoptera, and their 

 analogical relations with certain divisions of Ametabola, according 

 to which the whole Order resolves itself into five natural divisions, 

 I submitted the entire series of illustrations of the Metamorphoses 

 of Indian Lepidoptera contained in the Company's Museum to a 

 rigid examination ; reserving the indications afforded by this 

 examination, so far as regards the whole Order, to a future stage of 

 this Catalogue ; it is sufficient for my present purpose to state, 

 that in the first Tribe of this Order, the Diurnal Lepidoptera, or 

 Papiliones, I discovered five decided types of form, each of which 



* To illustrate the five types of form observed in the first Tribe of Lepidoptera, 

 the ]*apilione.s, and the corresponding analogies with the Ametabola, I have pre- 

 pared the accompanying plate exhibiting the larva and the analogous Ametabola.
