jiound-color of the wings, and in the outer edge of the middle band being 

 straight From the, costa to the median vein; while, in P. prunata, it is 

 deeply curved in. It varies in the width of the bands, especially (lie dark 

 median band, the scallops of which are sometimes deeply cul in, and in the 

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

 of t he band, whence the name disjunct-aria, under which it was iirst described. 

 The apical oblique line, and dark cloud beneath, and adjoining while zigzag 

 line, are much as in V. prunata. It is. in New England, much less common 

 than P. truncata, 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. miata (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 Mr. Willis. 



A Cidaria disjunctaria lias been described by La Harpe (Contributions 

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