Las Zorras ; December and January. At light.

 series of blackish spots ; fringe traversed by a grey 

 stripe ; body sordid-white. Expanse of wings, 28 mm.

 spots on the primaries, and by the colour of the 

 secondaries ; primaries above j)ale granite-grey, the 

 veins becoming black towards the tips ; an oblique abbre-

 almost to the median vein ; costal margin dusky towards
