ally on the upper side. Feet and legs also gray moiiled with black. Antennce witli 

 the shaft white, pectinations blackish. Primaries with a buff patch at the base, in 

 which aie a few black scales. Behind this a gray band, edged before and behind with 

 black, and sprinkled with black scales. Then a rather wide buff or fawn-color shade, 

 through which runs a waved rather indistinct blackish band. Behind this fawn-color 

 band is another of white or silver-gray, edged with a conspicuous dentate black line, 

 with some black scales towards the apex. The space behind the dentate line is pale 

 gray. Fringe whitish, flecked with black. Secondaries yellowish gray, shading 

 into dark smoky towards the margins. Underside .sordid white, dark on the apex of 

 primaries, with faint traces of a median band. E.xpanse of wings 30 mm. Length 

 ofbodyl2mm. 3 cf > ' 9- Denver, Colorado, lly. Edwards, I (^, Montana,

Gluphisia rupta n. sp. 



Head and thorax above white flecked with a few black scales, white beneatli. 

 Abdomen and antennce wanting in my unique specimen. Primaries with basal space 

 white with black central cloud. A very strongly marked black line runs quite across 

 the wing a little behind the basal third, and from its junction at the internal margin, 

 another line fainter and more oblique, and slightly dentate inwardly reaches the costa 

 at the apical third. The space between these two lines is stained with buff, and there 

 are a few black scales nearest the inner margin. Behind this is a broad space 

 limited by the dentate submarginal band, and clouded heavily with black. Second- 

 aries smoky, a little paler at their base. Fringes of both wings white, spotted with 

 black at the intersection of the nervules. Underside sordid white, the primaries with 

 a broad smoky submarginal band. Size of G. ridenda. i (^. Denver, Colorado.

The single specimen I possess of this species, was partially eaten by 

 cockroaches after its capture, but an early examination enabled nie to 

 pronounce positively as to its sex. 



Gluphisia albofascia n. sp. 



Ground color of primaries white with a yellowish tinge. Behind the small basal 

 space is a rather broad black band, narrowing a little towards the costa. On this arc 

 a few whitish scales. Then a broad yellowish white space, widest on the costa. 

 where it is stained with black, and behind this to the margin a blackish cloud, grow- 

 ing faint at the margin, and enclosing a dentate submarginal line. Secondaries pure 

 white, with a black shade at the anal angle. Fringes white with black spots at 

 the intersection of the nervules. Underside clear white, the markings of the upper 

 surface plainly visible. Fore tarsi distinctly banded with black. Expanse of wings 

 32 mm. Length of body 14 mm. 2 (^. Salt Lake City, Utah. Hy. Edwards. 



Gluphisia formosa n. sp. 



Size and appearance of the l.ist species, of which it may be but an extrenu- 

 variety. There is however, a very distinct .shade of buff crossing the middle of tin.- 

 wing, and the lines are all very faint, giving the in.sect a yellowish-gray appearance. 

 The primaries are only very sparsely covered with black scales, and the black anal 

 spot of the secondaries is wanting. IScnealh, a very distinct smoky median band 

 crosses the primaries, and appears on the costa of the secondaries in the sliape of two 

 spots. 4(1^,19. Salt Lake City, Utah. Hy. Edwards. '
