LARENTIDM-EUPITHECIA. 1 5 J. 



a dull white subterminal line ; cilia pale brown, dashed with 

 white. Hind wings narrow, rounded behind, white with 

 two black or brown sj^ots on the dorsal margin near the 

 base, and following them two to four rippled black-brown 

 partial transverse lines; beyond these are two or three 

 browner and much angulated lines or stripes ; cilia pale 

 brown, dashed with white. Female similar, or sometimes 

 larger and having the markings more distinct. 



Underside of the fore wings shining silvery whitish-grey,
