66 THE CANADIAN ENTOMOLOGIST 



This form has the central band of the fore wings clear white, the 

 intra- and extradlscal lines not touching. In most collections it 

 has been placed under truncata, in error, though the resemblance is 

 close, but beneath, on hind wings, the extradiscal line of citrata has a 

 much sharper angle. Punctum-notata Haw. occurs in most of the 

 Eastern States and a few of the Western, and also in British 

 Columbia. Packard seems to have found it quite abundant in the 

 White Mountains of New Hampshire, and has quite a series in his 

 collection from there. Mr. Prout has pointed out the distinctive- 

 ness of this aberration from truncata Hufn., and was one of the 

 first to do so. 



Ab. (b) immanata Haw. (Lep. Brit., U, p. 323, 1809). This 

 form has the prominent, reddish yellow costal spot, with central 

 band solid blackish gray, and brownish variegated outer margins. 

 It appears to be rather a rare form in North America, but it may be 

 more common in the north. I have specimens from Victoria, 

 B.C., received from Mr. E. H. Blackmore, and also from Mt. 

 Washington, New Hampshire. The black, central band will 

 distinguish it at once from all other forms. 



Ab. (c) simpUciata Walk. (List Lep. Brit. Mus., XXV, p.- 

 1422, 1862). 



This form has the central band blackish as in the aberration 

 immanata Haw., but there are white spots at costa and inner 

 margin. I have never taken exactly this form, the white spots 

 in my specimens not being intense enough, but rather grayish. 

 Possibly it is nearer the aberration tysfjordensis Strand. (Nyt. 

 Mag. Nat., XXXIX, p. 62, 1901). The latter form is said to have 

 a gray black central band with gray spots at costa and inner 

 margin. I list these two forms provisionally, but we get aberra- 

 tions which are very close to them if not identical. I believe these 

 to be rather northern forms and not very common. 



Ab. (d) insolida Prout (Trans. London Ent. Soc, p. 59, 1908). 



This form has the central band pale gray, with the inner and 

 outer lines on either side strongly contrasting black. I have two 

 specimens from British Columbia which approach it very closely. 

 The black, contrasting lines on either side of the central band will 

 readily separate this form from all others.
