Labial palpi, head, thorax and fore wings light gray, washed somewhat with 

 fuscous and heavily sprinkled with blackish scales, giving to all a blackish gray 

 appearance; basal field with two black spots along inner margin ; middle field 

 more heavily blackened over inner half, becoming often a blackish band ; outer 

 field lightest along outer margin, on which the blackish veins show distinctly ; 

 lines generally very distinct, white, lined on both sides with black ; the basal 

 narrow, twice dentate, somewhat oblitiue; the outer also dentate below costa 

 and near inner margin, and more finely between these two. Discal spot a white 

 lunule. Hind wings light pellucid fuscous, darker on veins and outwardly. 



The larva bores into and feeds upon Pines. It does not seem to 

 be very coniraon in America, though it is said sometime* to cause 

 great destruction to Pine forests in Europe. I have seen no descrip- 

 tion of the larva, but it probably resembles very closely in appear- 

 ance and habits that of P. Zhnmermanni Grt. Dr. Frey (Lep. Sch. 

 J). 273) says it lives in the pitch of Pine trees, and Siebke, in 

 "Schneider's Insects of Norway," says the adult larva hibernates 

 under mosses. The insect flies in June and July, and has been taken 

 generally in the Eastern States as well as in Texas and Colorado.

 costa as far from base as on inner margin ; middle space cinereous fuscous out- 

 wardly ; outer line white, angulated ; outer space with reddish, except at costa 

 and posteriorly; a marginal line of well-marked black dots and a black discal 

 spot on middle field; hind wings dark fuscous; margin black; all fringes light
