placed next lo ;i similar example received from Iceland through Dr. Staudin- 

 ger. labeled Ypsipetes sordidata Fabr. var., is not distinguishable l»y any char- 

 acters thai 1 can see. Other Califorriian specimens with shorter fore wings 

 do not differ much from the normal Iceland specimens, except in the genera] 

 color: the green shade being replaced in the Iceland examples by dark 

 reddish smoky-brown: the hind wings in the latter being darker than any 

 American individual. 



We shall look naturally for its occurrence in boreal Northeastern Amer- 

 ica. Staudinger gives the. following localities in Europe in his Catalogue : 

 Central and Southern Europe; Iceland; Piedmont; Italy; the Ural Mountains: 

 and Amur. 



In England, Scotland, and Ireland, Stainton and Newman report it as 

 being common ami very variable, appearing in July. 



The interesting variety originally described as a distinct species under 

 the name Hypsipetes nubilofasciata (pi. 8, tig. 31) not uncommonly occurs. 

 The fore wings are yellowish-white, and crossed by nine bands; the linear 

 basal line is directed obliquely outward from the costa. and sometimes 

 irregularly edged on each side with reddish scales, and is waved and angulated 

 in the median space. This is succeeded by a broad smoky band, widest in 

 the middle; just beyond which is a curved smoky-black band, widening 

 toward the costa and wavy toward the inner edge of the wing, and bordered 

 on both sides with reddish scales. Parallel, and just beyond, is the extra- 

 discal line, but a little narrower and less distinct (sometimes obsolete), and 

 bordered on each side with reddish scales, which do not reach the costa. 

 The median band is usually whitish, and varies much in width. Just beyond 

 this is a broad, sinuate, smoky band, irregular on the edges. The outer edge 

 of the wing is also smoky, forming a broad, marginal, smoky band ; a black- 

 ish, oblique, apical streak. Beneath, the hands are very faintly reproduced 

 on both wings; but their terminations on the costa of the lore wings form 

 five large, square, dusky spots, alternating with light ones. 



Specimens of //. californiata vary in much the same way as this; but it 

 may be distinguished by the outer edge of the fore wings being smoky. 



A rare and singular form (pi. 8, fig. 34), which I am, now that I have 

 had more material for study, inclined to regard as a variety of the present 

 species, was originally described by me as Hypsipetes albifasciata. 



This singular variety is more nearly allied to var. nubilofasciata than
