We may term this the Javanese Swallow-tail, for in 

 that and the other Indian islands it appears to be not 

 uncommon. We are indebted to the elegant Cataloyue 

 above quoted, for our figures of the larva and pupa , 

 and to the rich collection of Mrs. Children for the exam- 

 ination of the perfect insect. 



Entomologists will doubtless feel surprize that this and 

 the Protesilaus on our last plate, should be placed as 

 distinct types in two different genera. We have not 

 done this without long deliberation ; but we cannot, in 

 a work of this nature, enter into those details which 

 would demonstrate these divisions to be truly natural, 

 in the most rigid acceptation of the word. We desire 

 not, however, that Entomologists should adapt our views, — 

 at least for the present. We hope, indeed, that they 

 will not, because experience has shewn, that until a theorj 

 has been fully explained, more injury than good results 

 to science, from injudiciously adopting, and hastily applying, 

 a system not understood. We only desire, in short, to 

 record our views, that they may be comprehended hereafter. 

 We consider this as the Thrysanuriform type of the sub- 

 genus, and our English Papilio Machaon of authors, as 

 the Heliconian. — Tempus ducamus.
