34 LLOYD'S NATURAL HISTORY. 



species are more varied in their markings, though rarely 

 spotted, and are never transparent. 



The possession of a horny pouch in the females of many 

 species is remarkable, for it is a character which attains its 

 maximum of development in Parnassius, and other genera of 

 Papilionincz. The common Australian Acrcca andromache 

 (Fabricius) is mimicked by the female of Eurycus cressida 

 (Fabricius), a species belonging to a genus allied to Parnassius^ 

 and which, curiously enough, likewise possesses a pouch. 



The genus Acrcza was divided by Doubleday into six sec- 

 tions, which later entomologists have treated as genera or 

 sections according to their various views ; and one or two other 

 genera have been proposed since. But the genus Alczna pro- 

 posed by Boisduval for a small South African species, has 

 lately been removed from the Acrczincz^ as it proves to belong 

 to the Lyccznidcz*
