from the costa to the upper part of the second line are bluish- 

 grey. The sub-terminal line is yellowish, edged within by a 

 black line, and a row of black dots. The hind-wings are 

 lighter brown, with two slightly curved brown lines in the 

 centre, the pale marginal area being bounded by a zig-zag 

 yellowish line. There is an angular tooth on the hind margin 

 of all the wings, and the sub-terminal line is similarly angulated 

 outwards ; on the hind-wings this angle contains a brown 

 spot. 



GENUS FOCILLA. 



Focilia, Guende, Spec. Gen. Lepid. Noct. iii. p. 333 (1852) ;

 projection on the hind margin below the tip), and a strong 

 angular tooth or short tail in the middle of the hind margin on 

 the hind-wings.
