ing towards the discal dot. Discal dot very large, white, conspicu- 

 ous, partially bordered with black. Exterior line black, distinct, 

 commencing on the costa a short distance before the apex. There 

 are three acute projections on each of the costal nervules. From 

 the third costal nervule to the inner margin, the principal feature of 

 the line is two broad inward curves. The first is much the smaller, 

 having two lobes; extending to the second median nervule, from the 

 second to the third median nervule the line is nearly straight ; from 

 the third median nervule to the inner margin it forms a broad in- 

 ward curve, consisting of three lobes, the central one being the 

 largest, and nearest to the interior line. The entire central portion 

 of the wings, between the interior and exterior lines, uniform brown, 

 slightly lighter and with perceptible striae on the costa. Exterior 

 line, bordered externally with a broad white band. Entire submar- 

 ginal region of the wings, beyond the white band, covered with 

 brown spots and striae. A subapical, darker blotch, situated on the 

 border of the white band. Fringe dark brown, interrupted with 

 whitish, between the nervules. Posterior wings above (in all the 

 specimens I have seen except one), without any trace of lines or 

 discal spot. In one specimen the exterior line is quite visible in the 

 centre of the wings. Numerous brown atoms, particularly near the 

 outer margin. Outer margin and base of the fringe light yellowish 

 brown. Fringe white, interrupted with brown at the termination of 

 the nervules. Anterior wings beneath with the markings above 

 partially reproduced, costal margin and apex more distinctly, yellow- 

 ish brown. Posterior wings beneath, very thickly sprinkled with 

 brown atoms. Exterior line present, distinct, brown, dentate, 

 followed by a whitish band free from atoms. Discal dot absent.

This species is very different from any described North American 

 Cidaria. It can be recognized at once by the conspicuous white 

 discal dot, and by the distinct lines of the anterior wings above, 

 bordered with white.
