126 THE CANADIAN ENTOMOLOGIST. 



The specimen in Mr. Belanger's collection differs from all of my 

 specimens in having the dorsal spot prolonged towards the apex till it 

 meets in the apical part of the wing with the second costal streak, in 

 having the apical spot more definite, and the dusting in the ciliae so 

 arranged as to form two short hinder marginal lines. I have no doubt it 

 is the same species. The pattern of ornamentation (not the colors^ of 

 this species is almost exactly that of the right wing in Mr. Stainton's 

 figure of B. demaryclla, but the left wing in the figure is very different.

In the collection received from Mr. Belanger is a single specimen of 

 this species, together with the mined leaf of poplar, from which it 

 was bred. It has heretofore been found only in Willow leaves. It is an 

 exceedingly variable species, some specimens being so densely dusted with 

 brown or gray brown scales as to suggest a resemblance to the European 

 species L. populifoliella, whilst others are almost free from dusting, and 

 may be described as having a ground color of pale golden or saffron 

 marked with white. In the former description of this species I was led 

 by the resemblance of the more densely dusted specimens to L. populi- 

 foliclla, as figured by Mr. Stainton in Nat. Hist. Tin., v. 2, and the position 

 in which L. pastorella is there placed in his classification of the species 

 of this genus, to suggest that it might be identical with pastorella. Per- 

 haps the following description may convey a better idea of an average 

 specimen than the one previously given. 



Thorax and primaries bright golden or saffron yellow, according to the 

 light, or even sometimes dull brownish yellow, the thorax and basal 

 portion of the dorsal margin of the fore wings being largely intermixed 

 with white and dusted more or less with black ; sometimes the inner angle 

 is of the general ground hue, scarcely dusted or marked with either white 

 or dark brown, and then there is a median white basal streak which meets 

 at an acute angle with a dorsal white streak about the basal fourth of the 

 wing length. Both of these white streaks and all other white markings 

 on the wings are more or less dusted with dark gray brown, sometimes so 

 much as to obscure the white. Before the middle of the costa is a long 

 white streak, which attains the middle of the wing, curving backwards ; a 

 little behind this, on the dorsal margin, is a large dorsal white streak, wide
