$ . Wing shape the same as the female. Fore wings with the ground over- 

 washed with ocherous and gray or entirely gray, leaving narrow white edges to the 

 markings. Discal dot large, reniform, white, edged with black without ; a black 

 triangle with white mark without on middle of costa and spot opposite it on internal 

 margin, both white-edged ; a small spot cut by white subapically, in well-marked 

 specimens joined to the outer edge of reniform and beneath it to the middle costal 

 spot, a fine white line being continuous, though broken in pale specimens ; a black 

 subbasal toothed line : a terminal white line, touching margin at middle, produced 

 inward between the veins, diffused. Hind wing nearly white, a little ocherous 

 shaded ; central lines white, diverging mesially, edged within with gray and enclos- 

 ing a white discal space and a smaller one near margin ; a white terminal space, fol- 

 lowed by a dark line. Markings not sharply defined, varying to subobsolete. Ex- 

 panse, 17 to 21 mm. 



9 . Fore wings suffused and obscured, unicolorous, only slight traces of the 

 markings persistent. Sordid ocherous, brown-gray or dark cinereous, 'very variable in 

 color. Hind wings as in the male but more faintly marked, in white and pale gray 

 only. Expanse, iS to 24 mm. 



Professor Fernald has sent me a specimen purporting to be one of 

 Hulst's types of gyralis, but it is a 9 °f -N. obliteralis Walk, from 

 Texas, a locality not mentioned by Hulst in his original description, 

 and it is obviously a spurious type. The sexes are strongly dimor- 

 phic. Hart correctly identifies the female, of which I have many, 

 taken in company with normal males.
