brown, leaving' only the basal third of co.stal margin and the outer 

 margin really greyish; the inner margin darkest to postmedial line; 

 traces of a dark basal line; three black antemedial wavy lines; a liuui- 

 lar greyish brown streak at end of cell; a postmedial, geminate, dark 

 brown line from costa to vein 3, divided b}^ a grey shade; from below 

 end of cell the line is only partly geminate; the postmedial is followed 

 by a brown shade on which is a series of dark velvety streaks between 

 the veins above 3, and most heavily marked toward costa; submarginal 

 brown irrorations; a marginal black line, wavy below vein 3; fringe 

 whitish mottled with dark grey. Secondaries whitish; the costal and 

 outer margins broadly black; the inner margin shaded with dark 

 brown; fringe white. Underneath primaries, ])lack; some white 

 markings on costa near apex. Secondaries as above, but the inner 

 margin white. 



Expanse. — 38 mm. 



Ilahltat. — St. Laurent, Maroni River, French Guiana. 



What I believe to be the male of this species has the primaries 

 lighter grey, and the antemedial and postmedial lines shaded on inner 

 margin with 3"ellow and white; some yellow at end of cell, and at base 

 below median vein.

RIFARGIA MERITA, new species. 



I described " as the female of Rifargla plcta a species which turns 

 out to be quite distinct. As I now have males and females of both 

 forms, showing that the markings of the sexes agree, it will require a 

 name. The specimen 1 described as a female is really a male, the 

 antennae being fasciculate; the female antenna? are simple. 1 propose 

 the name me'rlta.
