Eiicosma bobana sp. uov.

Head: pale clay-yellow; palpi same, dusted with fuscous outwardly, apical 

 joint fuscous.^ antenna pale clay-yellow, the segments dusted with brown ; thorax 

 pale clay-yellow, shaded with bright ochreous-brown in front and at base of 

 patagia ; thorax and legs whitish-gray, the latter dusted with light browu. 



Forewing: alternate bands of bright ocherous and dark reddish-brown, these 

 bands are broken and their direction changed at the middle of the wing, giving 

 the surface a checkered appearance. The extreme base is narrowly white, fol- 

 lowed by a wider ochreous baud, then by a white band, marked below fold with 

 an ochreous spot and on upper vein of cell with a brown spur from the next 

 outer fascia, the latter begins at inner fifth on costa as a blackish streak, becomes 

 narrow below costa to middle of wing, then widens to dorsal margin which it 

 reaches at inner quarter, below the costa it is ochreous and browu, outwardly 

 edged with dark brown. It is followed by a broader ochreous fascia, interrupted 

 just above middle by a spur from the succeeding dark fascia. The latter begins 

 as a rich brown spot on costa to upper vein of cell, where it is cut by a horizon- 

 tal streak of black and brown scales, the downward continuation of the fascia 

 starts from outer end of this streak, and is rich brown, having a strong lobe on 

 its outer edge. Beyond this, above middle of wing, is a large patch of ochre- 

 ous and white scales, with two brown dots on costa. Beyond it is a subapical 

 brown and black patch, triangular in shape, with a point touching costa, an inner 

 spur below the yellow patch before it, and a curved streak along the lower half 

 of termen, this latter streak becomes yellow shortly before the middle. On tlie 

 lower half of outer fourth is a curved ocherous 'patch, with a small dash of fus- 

 cous scales at anal angle. The ochreous patches and fascise are all outlined by 

 white, and the brown patches usually outlined by black or darker browu. Cilia
