74 LLOYD'S NATURAL HISTORY. 



above, with red spots at the anal angle of the hind-wings ; 

 beneath, it is white, with a slender incomplete red line. The 

 thick rounded pupa is remarkable for being " attached with 

 silk, by the tail only, horizontally on the under side of a leaf ' 



( Trimen). 



GENUS SITHON.

The types of this genus are confined to the Indo-Malayan 

 Region, and may be known from their allies by the sub-costal 

 nervure of the fore-wings having only three branches, the 

 first impinging on the costal nervure. The wings are rather 

 short and broad, and the hind-wings have a slender tail, and 

 the anal angle produced into a long lobe. 



With these insects are frequently associated a number of 

 East Indian and African Butterflies, sometimes called Sithon 

 or Myrina, varying in the number of branches of the sub-costal 

 nervure ; most of them are remarkable for having a very long 

 tail on the hind-wings, and frequently a much shorter and more 

 slender one on each side. The Eastern species of this section 

 have been divided into a variety of genera (Biduanda^ Cheritra, 

 &c.) by Distant, Moore, and others. Most of these genera 

 will doubtless be retained ; but we have not space to discuss 

 them in detail here. 



The true type of the genus Sithon is 



SITHON NEDYMONDA.
