DIORHINA. 29 



of the fore-wings is perfect. This sub-section includes some 

 of the largest and handsomest species of Lemoniincz. Most of 

 them are tailed species, and some of these are very like Zeonia 

 in shape, though generally with narrow white bands, instead of 

 broad transparent ones. These include the types of the old 

 genus Erycina^ and therefore some of the most typical forms 

 belonging to the Family. The fore-wings are usually short and 

 broad, scarcely extending beyond the hind-wings, which are 

 long, and often more or less tailed.

This genus is closely allied to the next, and is chiefly dis- 

 tinguished from it by the longer palpi, the usually longer tails, 

 which are less curved outwards, and the absence of metallic 

 colour on the under side, notwithstanding that the males are 

 usually more or less blue above. 



The type is
