Forew/»i/s : jiale dull yellow; the lines i'lUiit, rust-coloui-; tirst at one-fonrtli, 

 curved outwards above and below the median vein; exterior line obliiine, starting 

 from a large red-brown costal spot shortly before apex; cell-spot i'ainlly darker; 

 fringe concolorous. 



Hindtvings : with a single central brown line. 



Underside bright lemon-yellow, with some rust-colonred tleeks; forewings with

Expanse of wings: 32 mm. 



Several from Costa Rica. 



Along with the type-form occurs another, in which the lin(!s are more strongly 

 marked; both wings are thickly speckled with ferruginous, and the marginal area

Antennae of c? simple, faintly pubescent; palpi short, porrect; second joint 

 hairy; third short, pointed; tongue and frenulum present; hiudtibiae with four 

 spurs. 



Neuratioii: forewings, cell two-thirds of wing; discocellular vertical; first

 oblique and straight inwards to inner margin at one-third, preceded by a pale line 

 of ground-colour; second line from costa at two-thirds, oblique outwards towards 

 the middle tooth, there forming a blunt angle, and sinuate inwards to inner margin 

 at two-thirds; cell-sjiot blackish; beyond this fascia two or three obscure dark lines 

 are visible, and a snuill si)ot above the jirojection; fringe olive-grey. 



Hindtvings : whitish, simply dusted with grey; cell-spot large, blurred; two 

 dark grey sjiots ou inner margin above anal angle, denoting the commencement of
