epicranial suture deep ; cranial lobes hemispherical, with scattered 

 hairs. 



" The pupa measures .45 of an inch. It is light pea green, 

 turning white before the moth escapes. There is a clear dorsal 

 space with an interrupted white line in the middle ; also white 

 lines on the lateral faces. The tubercles are set with hairs ex- 

 actly as in the larva, so the pupa is quite conspicuously clothed ; 

 the head and thorax support shorter hairs arising singly from the 

 surface ; short, dusky hairs stand in rows on the wing covers, ap- 

 parently outlining the veins ; there is a similar row on the antennae 

 covers. The pointed cremaster ends with many booklets, which 

 fasten the pupa securely to the leaf, on which a tuft of silk has 

 been spun by the larva. The thorax is quite obliquely truncated ; 

 seen from below, it is slightly bilobed, rendered so by the promi- 

 nent origin of the antennae covers ; between the lobes there is a 

 slight tufted tubercle." (Kellicott.) 



PTEROPHORTJS BRUOEI, n. a. 



Expanse of wings, 24-26 mm. Head and thorax pale ashy 

 gray, with the tegulae much lighter. 



Fore wings white, with a few brown scales scattered over the 

 surface, most numerous basally and along the costa. An elon- 

 gated brown spot on the cell near the basal third of the wing ; a 

 triangular brown spot on the end of the cell immediately before 

 the fissure, indistinctly connected with an elongate brown spot on 

 the costa above the end of the fissure; a similar spot occurs 

 near the middle of the costa of the first lobe. Fringe of first 

 lobe whitish on the costa and fuscous from the base of the cleft to 

 the apex, immediately before which it is cut with white, and there 

 is a brown spot on the wing at the base of the white. Fringe of 

 second lobe fuscous within the cleft and whitish elsewhere. Hind 

 wings pale fuscous, with the fringes a little darker than the sur- 

 face of the feathers. 



Early stages and food plant unknown. 



Described from three examples collected in Colorado by Mr. 

 David Bruce, whose work in the west has enriched many museums 

 and private collections.
