joining the internal margin midway between tlie angle and the base of the 

 transverse posterior line. It is of an intense deep brown with a thread-like 

 white outer border. The gray terminal space is thus divided by it into unequal 

 portions. An interrupted black terminal line; the gray fringes are a little 

 produced at the extremity of the nervules. Hind wings obscure ochrey white, 

 with a light brownish diffuse exterior shade ; the nervules incompletely marked 

 with dark scales and a subcontinuous marginal black line ; fringes whitish 

 with an internal dark line. Tegulae gray, contrasting with the light brown 

 collar and thoracic disc and tuft ; abdomen colored like the secondaries. Be- 

 neath the wdngs are pale, shaded with reddish over the apices and costal mar- 

 gins, sparsely dusted with dark scales, with a common exterior line emphasized 

 on the veins and faint discal dots more apparent on the hind wings ; a faint 

 subterminal line appears contrasted by the difference in tone of the subterm- 

 inal and terminal shades.

^ . — At first sight, and with a different locality, the specimen I re- 

 gard as belonging to this species, would not be considered as refera- 

 ble to it. The thorax and fore wings are uniformly gray sprinkled 

 with darker scales. The reniform is coucolorous and both spots rel- 

 atively larger. The most prominent difference is expressed by the 

 absence of the contrasting light and brown color of the subterminal 

 space, which is here coucolorous. The subterminal line is, however, 

 here brown, distinct, and in its general course the same as in the 

 opposite sex ; it forms a more evident W-shaped< mark by its denta- 

 tions on veins 4 and 3 ; it runs backward above vein 8 to costa, 

 leaving the apices gray; however a faint trace of this action is visi- 

 ble in the female, in which the apices are coucolorous and apparently 

 fused with the subterminal space. The hind wings are more whitish 

 with a more determinate darker band and beneath the specimen 

 lacks the reddish shade of the female, with an otherwise similar 

 appearance of the wings.
