15. Perigea niveopicta, n. s. 



Primaries above dark fuliginous-brown, with slight 

 violet and bronze reflections ; the ordinary black lines 

 indistinct, the outer one denticulated ; the spots enclosed 

 by these lines also indistinct, those on the interno- 

 median intersi^ace only outlined in black, but the orbi- 

 cular and reniform with white-dotted margins, the 

 "orbicular" Q-shai^ed, the "reniform" f) -shaped, the 

 white edging being absent from the lower extremity ; a 

 discal series of snow-white dots ; a marginal series of 

 small black spots ; fringe traversed by a blackish crenu- 

 lated stripe ; secondaries pale shining bronze-brown ; 

 fringe whitish (white towards anal angle), traversed close 

 to its base by an undulated dark brown stripe ; body 

 fuliginous-brown, with a slight violet tint ; abdomen 

 whitish towards the base ; thorax with lateral zigzag 

 black lines ; wings below fuliginous-brown, shining, 

 whitish at the base ; a dark slightly undulated discal 

 stripe ; a marginal series of black lunules, only visible 

 in certain lights ; costal areas irrorated with dark grey 

 scales ; primaries with whitish internal border ; fringe 

 speckled with blackish atoms, and traversed by a dark 

 crenulated stripe ; secondaries with pearly whitish 

 abdominal area ; a blackish spot at the end of the cell ; 

 fringe whitish, with an undulated stripe as above, but 

 only visible in certain lights ; pectus greyish, but the 

 hairs white underneath ; the legs pinky brown, grey- 

 speckled, and with greyish tarsi banded with whitish 

 above ; venter greyish, with pink reflections. Expanse 

 of wings, 31 mm. 



One male, taken at " Las Zorras in February." — 

 T.E. 



What appears to me to be the female of this species is 

 a moth taken with a variety, or perhaps a very closely 

 allied species, in the same locality, and separated by 

 Mr. Edmonds under a different number : it only differs 

 from the male in its more strongly defined markings, the 

 ordinary lines being represented by black-edged lunular 

 spots of the ground colour ; the interno-median sjDots 

 being dark as well as black-edged, and the discoidal 

 spots white-speckled as well as white-edged ; the discal 

 series of dots is, however, less conspicuous, the dots not 

 being of so pure a white. Expanse of wings, 33 mm.
