LEPIDOPTERA. 119 



crowded. This division is exemplified in the following species of 

 this Catalogue, viz. : — 



Papilio Sarpedon (No. 22G). [ Papilio Agamemnon (ISTo. 229). 

 Papilio Antipathes (No. 232). 



And the metamorphoses of the same species, which are figured on 

 Plate III., figs. 8, 9, and 10. 



The larva of this division is smooth, slightly attenuated towards the 

 extremities, somewhat broader or arched in the middle, and marked 

 with regular transverse bands ; but its chief character consists in two 

 projecting points from the abdomen. It forms the Thysanuriform 

 division of the genus Papilio. 



The three divisions of the genus Papilio which have here been 

 defined from the materials in the Museum, afford an indication of 

 several distinct types of form, which in the larva state have an 

 evident affinity to the Chilognathiform, Chilopodiform, and the Thy- 

 sanuriform Ametabola ; while, in each of these separate groups, the 

 imago manifests a character which reciprocally confirms the distinct 

 character of these divisions. 



Whether in collections of greater extent and from more extensive 

 regions, the Yermiform and Anopluriform representatives may be 

 discovered, is a subject which remains for future research. 



The general principle on which these divisions have been esta- 

 blished, is in perfect consistence with the law above cited ; namely, 

 that in groups of consecutive minor value, the same principle is often 

 found to prevail: of which, Messrs. De Haan and Vigors aflford 

 ample confirmation. 



Without entering on further details, I submit this poi»t to the 

 consideration of Entomologists. — (Horsfield.)
