Ash gray, median space strongly and variably snftnsed with black ; 

 a costal patcili in s. t. space dusky. Transverse lines <listinct, single; 

 t, a. line upright, very little waved; t. p. line finely crenulate, about- 

 ])arallel to the outer margin ; s. t. line even, preceded by a series of 

 sagittate black dashes. A basal black streak. Claviforin distinct, 

 black. Ordinary spots distinctly outlined, gray; renitbnn witlv a cen- 

 tral dusky line. Orbicular variable in size, usually small ; round. 

 Cell filled with black. Secondaries dusky ; a darker discal and termi- 

 nal shade line and <liscal lunule. lieneath pale, with a distinct, broad, 

 powdery, transverse line, and a distinct discal lunule on each wing. 

 Head and thorax concolorous ; collar with a broad black shade. 



Expands 3'2-37""" ; 1.1*5-1.50 inches. 



II ABIT AT. —New Hampshire, Mount Washington, Labrador. 



Mr. Grote was coirect in referring opipara and islandica Moeschl. {nee 

 Stgr.) as synonymous. The error is Moescihler's, in failing to recog- 

 nize the distinction between the forms, and Mr. Grote's for so positively 

 condemning Mr. Morrison's species on insuflicient ground.s. Mr. Morri- 

 son was also <!orre('t in describing his specimen as distinct. The Lab- 

 rador specimen before me is smaller, rather shoiter winged, than the 

 Mount Washington specimens, but not otherwi.se distinct. Fufortu- 

 nately all are females, and I can not find in literature any descrij)tion 

 of a male. It is barely possible, therefore, that the species does not 

 belong to this group.

Pale, somewhat luteous gray, the transver.se' lines obsolete; s. t. 

 line indicated by a row of fuscous spots. A basal black dash. Ordi- 

 nary spots concolorous, large, incompletely outlined; a triangular 

 black spot before orbicular ; a quadrate patch between the spots.
