Fore wings yellow-buff, so sprinkled with brown scales as to appear

 ated by the vein, the sixth very small ; the sixth row is of nine spots, all 

 white but the costal, the first, second and ninth very small, the seventh

 others. The last spot in four of these rows is below the submedian vein. 

 Fringes brown, with buff at the ends of the veins. Hind wings pale buff, 

 a pale stain spot at the end of cell and at the apex. 



Head yellow in front, brown between the antennje, antennae pale yellow

Collected in Colorado by Mr. David Bruce. Described from one 

 male. This species is near H. Scapidaris Stretch, but differs in size, 

 colour and markings. In Scapular is all the spots are white, and the 

 ground color is brown, with the thorax brown instead of buff. These are 

 a few of the differences between the two species.
