152 THE CANADIAN ENTOMOLOGIST. 



behind is a fan-shaped dark brown patch at the base of the apical cilia. 

 ■Ciliae silvery, (7;/^/ not containing a black streak from t/ie apical spot to the 

 apex. 



The italics above indicate the differences between it and A. splcndori- 

 ferclla, and besides, it is much smaller than either that species or A. eila, 

 ha\ing an alar ex. of less than yi of an inch, and thus smaller than 

 Nepticula niicrot/ieriella, which, Mr. Stainton says, is the smallest hereto- 

 fore known Lepidopteron. Besides, the antennae are not so distinctly 

 fuscous as in splcndoriferella, and the golden portions of the wing are not 

 so deep or reddish golden as in that species. It resembles that species 

 more closely than either A. ella or A. lucifluclla. The pupa case is 

 oblong ovate, brownish, not so much pointed at the anterior end as that 

 of A. Jiiglandiella, and is a little smaller. 



Dr. Clemens found a mine and larva in the leaves of the White Willow 

 ■(SaUx alba)^ which he called A. saliciella, but he was not acquainted 

 with the imago. I have not met with that mine, my species having been 

 bred from the Weeping Willow. But as I have no doubt that it is the 

 same species, I have adopted his name.

In the description of this species I have used the word "before" where 



I should have written " behind," as to the location of the costal streaks \ 



and the whole description is so unsatisfactory that I wish to redescribe 



it. It is, however, difficult to get a good description of a species which 



•does not present the same appearance in any two views of it. 



Head, palpi, thorax and basal half of the priniaries pale grayish 

 silvery. Antennce fuscous above, silvery beneath. Apical half of the 

 primaries black along the dorsal margin, the black spreading over the 

 middle of the apical portion of the wing to the golden yellow costal part 

 of the apical half of the wing. This golden yellow costal portion 

 extends along the entire costo-apical margin, and along the middle of the 

 apical portion of the wing it passes gradually into, or blends with, the 

 blackish dorsal portion. (Perhaps a more correct description would be : 

 apical half of the wing golden along the costal half, blackish along tlie 

 dorsal half, the two colors meeting and blending with each other in the 

 middle, and the black passing into tlie base of the dorsal cilia.) In some 

 lights the golden is strongly tinged with red, and the black becomes a 

 deep golden brot\'n. /// the Uack dorsal poi'tion, behind the middle of the 

 dorsal margin, is a triangular silvery streak ; and opposite to it, in the
