nate, and to it are attached the orbicular and claviform spots. It 

 is notched on the costa, then joining the orbicular spot, and below 

 the latter forming one outward lobe to the inner margin. Orbicular 

 spot elliptical, strongly contrasting, whitish, with an internal green 

 shade spot; it opens into a basal, costal, greenish white shade. The 

 lower part of the basal space is less green, and contains a large, deep 

 brown spot situated in the lobe of the interior line. Claviform spot 

 concolorous, with its upper line alone distinct; extending, as well as 

 the orbicular, to the median shade, which is seen as a thick black 

 line parallel to the border of the dark space. The outer half of the 

 wing is clearly whitish in the median space, shading into light green in 

 the subterminal and terminal spaces. Reniform spot barely percepti- 

 ble. The lines sub-obsolete. The exterior line is most clear opposite 

 to the cell; there it is dentate, of the usual shape, and followed by 

 dark points on the nervules. The subterminal line is white, irregu- 

 lar, forming two blunt, Hadena-like teeth on the second and third 

 median nervules. The upper portion of the subterminal space 

 slightly darker. A longitudinal black dash on the first median nerv- 

 ule in the terminal space. A series of fine black lunules at the base 

 of the fringe, which is dark, intercepted with ochreous, and with a 

 continuous central dark line. Posterior wings whitish, with a discal 

 dot, a twice angulated median line, and a diffuse blackish terminal 

 shade. Fringe concolorous. Beneath, the anterior wings are dark, 

 lighter along the inner margin and in the terminal space. The reni- 

 form spot and the exterior and subterminal lines are faintly repro- 

 duced. Posterior wings whitish, with a discal dot and exterior line.

This species can be easily identified by its strongly contrasting 

 markings and colors, which resemble in their disposition those of 

 the only other and closely allied species of this genus, the European 

 Demas Coryli.
