and very conspicuous, while it is usually nearly obsolete in Plagodis. In 

 coloration, also, the two genera differ decidedly, the cxtradiscal line being 

 produced into a long angle, while in Plagodis there is no angle, but the line 

 is straight in its course. The female antennae are also narrowly pectinated, 

 where they are simple in Plagodis.

12 <? and 3 9. — Pale whitish-ash, with rather thick blackish speckles. 

 An inner curved line pale brown, dilated on the costa, frequently fading out 

 before reaching the hind edge of the wing; the outer line forms a great 

 angle in the first median cell, the point near, but at varying distances from, 

 the outer edge. Beyond the line, the wing is brown, either reddish or umber 

 brown, with dark strigse, and a pair of diffuse black spots just below the 

 third median venule, one just about the point of the outer line, and one just 

 below the costa near the apex, the latter having an oblique, pale, broad streak. 

 Hind wings like the anterior pair; but the outer line is sinuate, not 

 deeply angulated, and the edge of the wing is either clear, like the rest of 

 the wing, or filled with reddish-brown, as on the fore wings. Beneath, as 

 above, but much more thickly speckled, with the four discal dots plainer 

 than above. Veins brown, lines as above (inner line on fore wing wanting).
