<Tioiiii(l-f()l<>r iirtlic wiiiifs, and in the outer edge of the middle band l)eiiig 

 straiiilil from (lie costa to the median vein; while, in P. pnwafa, it is 

 deeply curved in. It varies in the width of the hands, especially the dark 

 median hand, the scallops of which are sometimes deeply cut in, and in the 

 suhmedian space forming an elongate, oval, black spot, separated from the rest 

 of the baud, whence the name disjunrtdiiii, under which it was first described. 

 The apical ol)lique line, and dark cloud beneath, and adjoining white zigzag 

 line, are much as in P. pn/)nifa. It is. in New England, much less common 

 than /'. trunratd, and perhaps more so than P. prunata, which seems to be 

 a more boreal and subalpine species. Whether it may not prove identical 

 with some European species is a question. It seems to be allied to the 

 European P. m'lafn (Linn.), which, according to Staudinger's Catalogue, 

 inhabits Central and Northern Europe, Piedmont, Southern and Western 

 Turkey, and the Ural Mountains. 



This agrees well with Walker's description and a drawing of his type 

 received from IMr. Willis. 



A Cidnria disjundaria has been described by La Harpe (Contributions 

 k la Faune de la Sicile, Lausanne, 1860).
