270 LEPIDOPTEBA INDICA. 



Cyaniris and Zizera. The dorsal portion (tegumen) consists of a central piece, with 

 two horns jointed to it, both of very similar form and structure to those of Everes 

 (Cyaniris and Zizera have the dorsal armature in two lateral portions, the actual 

 dorsum being merely part of the chitinous ring of the ninth abdominal segment with 

 no armature). The claspers have the two processes (characteristic of Lycsenids) of 

 nearly equal size, each being very long and slender, but reminding one a good deal of 

 Everes. In Cyaniris and Zizera the ventral soft (i.e. unarmed with spicules or teeth) 

 process is nearly or quite obsolete (Chapman).
