size, and beset with erect hornlike processes : but the chief charac- 

 teristic of this division consists in two very strongly marked length- 

 ened filiform or spinous appendages at the extremity of the abdomen. 

 The pupa is attached by the tail and suspended perpendicularly, as 

 in the last division ; its head is in general terminated by two points 

 of various form and length. Representing the Thysanuriform 

 Ametabola. 



Fifthly. A cylindrical larva, nearly naked, with a very large 

 head, often globular, and attached to the body by a long neck ; 

 characteristically distinguished from the other subdivisions by its 

 bluntness and abrupt termination behind ; the pupa being covered 

 by a convoluted leaf. Representing the Anopluriform Ametabola. 



These separate groups, agreeably to the plan of Mr. Macleay, in 

 the " Annulosa Javanica," will be denominated stirpes. 



Tabular Review of the Larvm and their Analogies above enumerated. 



1st Division, named according 1 v 'f 



to the form of the larva j 

 2nd Ditto Juliform or Chilognathiform. 



Srd Ditto Scolopendriform or Chilopodiform. 



4 th Ditto Thysanuriform. 



5th Ditto Anopluriform. 



To answer the question which may arise, whether, in applying to 

 one Tribe of Lepidoptera — the Papiliones — the same principle 

 which Mr. Macleay has applied to the whole Order of Coleoptera, I 

 have not departed from his scheme ? I oiFer the following con- 

 siderations : — Mr. Macleay has divided the whole Animal Kingdom 

 into quinary groups, which are again subdivided into groups of 

 consecutively descending value : thus, the Animal Kingdom is 

 divided in descending order into Sub-kingdom, Class, Order, Tribe, 

 and Stirps. This arrangement is fully exemplified in the Diagram 

 of the whole Animal Kingdom, on page 318 of the " Horso Ento- 

 mologies)," and in that of the sub-kingdom the " Annulosa,'' on 

 page 390 of the same work ; to which I refer the reader. The 

 same law of groups of consecutively minor value has been observed 

 to prevail in Birds by N. A. Vigors, Esq., and in Crustacea by 

 Dr. De Haan, of Leyden, who thus expresses himself: — " Methodum 

 quinariam, cujus in hac invertebratorum classi specimen Entomo-
