 norax, Druce, differs from Cossula and Costria in having veins 7 and 

 8 on primaries stalked. The other species described by Druce under 

 Atbela, I have not been able to examine. 



Givira Walk. 



Antennse pectinated. Palpi extending beyond frons. Primaries : veins lb and 

 Ic connected by a bar ; 2 and 3 far apart ; 5 near 4 ; 6 from upper angle of cell, 7 

 and 8 stalked from areole ; 9 from areole, 10 and 11 from cell. Secondaries 6 and 7
