 Head and thorax fuscous gray or cinereous; dorsum of thorax rich, deep 

 chestnut brown, widening toward base. Thorax fuscous, silky, with a slightly 

 darker dorsal line and a series of indefinite paler lateral spots. Primaries ash 

 gray, shaded and maculate with fuscous brown. Basal space pale, with a dusky 

 shade, crossed by an indistinct whitish baud. A little beyond basal third of costa 

 adusky, outwardly oblique band crosses the cell, widens into abroad shade below, 

 acutely angled below vein two, thence inwardly oblique to the inner margin 

 about two-fifths from base. A tolerably even, not very definite whitish shade 

 runs from apical fourth of costa to the inner margin about one-third from hind 

 angle. Within this, just beyond the cell, is a still more indistinct light fuscous 

 shade line parallel to it; below the cell the space between the augulated basal 

 line and the outer pale oblique line is dark fuscous brown ; a pale, yellowish 

 discal lunule, dividing a small discal spot; veins marked with yellowish beyond 

 the cell. Beyond the whitish shade line the wing is darker, crossed by a lightly 

 scalloped and somewhat sinuate pale band inwardly margined with darker fus- 

 cous ; a powdery, pale subterminal gray shade widening at anal angle and at 

 apex. Throughout, the costal region is suffused with gray. Secondaries rosy 

 red, the margins fawn colored ; a large ocellate spot near anal angle black ringed, 

 blue centred and with a black pupil ; connected with anal angle by a black spur 

 from the outer black ring. Beneath, the primaries are rosy at base, the yellow 

 discal mark prominent, outwardly fuscous, with gray powderings, the macula- 

 tion of primaries reproduced. Secondaries gray, with fuscous powderings, outer 

 margin ratlier darker, two parallel, fuscous transverse lines. Expands 3 — 3.15 

 inches ; 75 — 79 mm.

This species is so extremely rare that very little cau be said of it. 

 The specimens have been very generally captured at light, and the 

 early stages are entirely unknown. The side piece of the male 

 seems broader than in its allies, the corneous processes very much 

 as in ophthalmicus. 



The species was long considered as synonymous with geminatus as 

 no further specimens were obtained, but there is not the slightest 

 doubt of its distinctness. It has also borne most of the generic 

 terms proposed for this grou}), until it was finally made typical of a 

 distinct term. It is rather more powdery than any of its allies.
