518 ANALYSIS. 



I have thus attempted to find characters for the natural 

 groups which appear on disposing the Gymnopleuri ac- 

 cording to their affinities $ but the proper method of con- 

 sidering them all is, as referable to one or other of forms 

 which may be expressed by the five following species : — 



1. azureus. 



2. flageliatus. 



3. c&rulescensi 



4. Kcenigiii 



5. miliaris. 



In almost every group which has been set before the 

 reader, he must have perceived that one of the five minor 

 groups, into which it is resolvable, bears a resemblance to 

 all the rest ; or, more strictly speaking, consists of types 

 which represent those of each of the four other groups, to- 

 gether with a type peculiar to itself. This is visible in the 

 composition of the Acrita, among the divisions of the Ani- 

 mal kingdom ; in that of the Ametabola, among the classes 

 of Annulosa \ and of the Coleoptera, among the orders of 

 Mandibulata. It is a disposition also which can scarcely 

 have escaped our notice on examining the genus Phanaus, 

 the fifth type of which contains insects resembling all the 

 other types, together with P. Carnifex, which has a form 

 peculiar to this fifth type. What this fifth type is to Pha- 

 nceus, Gymnopleurus is to the genus Scarabaus ; that is, 

 while it has a form peculiar to itself in G. Jiagellatus, it 

 contains insects varying in the structure of those parts 

 which remain constant in the other sub-genera. 



To minds that delight in tracing design amidst those 

 circumstances which seem in our eyes the least to require 

 it, it will always be interesting to observe the limits by 

 which nature has circumscribed the locality of animals,
