 irer. labeled YpsijH-tcs sordidata Fal)r. rai:, is not dis1in!,niishal)le by any char- 

 acters that I can see. Other Californian siie(nniens with shorter lore wings 

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

 color; the green shade being replaced in the Iceland examples by daik 

 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 tbllowing localities in Europe in his Catalogue : 

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

 and Amur. 



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

 being common and very variable, appearing in July. 



The interesting variety originally described as a distinct species under 

 the name Hi/jjsijjcfes nuhUofasclata (pi. 8, fig. 31) not uncommonly occurs. 

 The fore wings are yellowish-white, and crossed by nine l)auds ; the linear 

 basal line is directed obli.quely outward from the co.sta, 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 v\avy 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, snujky band ; a black- 

 ish, ol)lique, apical streak. Beneath, the bands are very faintly reproduced 

 on l)oth wings; l)ut their terminations on th.e costa of the fore wings fn-m 

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



Specimens of H. californmta 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 (])1. S, fig. 34), which I am, now that I have 

 had more material i'or study, inclin(>(l to regard as a variety of the present 

 species, was oi-iginally described by me as Hypsipcles albifasciata. 



This sinyular varicfy is more nearly allied (o var. nnhilofaxciata than
