golden costal portion, is another, the two ahiiost meeting so as to form a 

 fascia, and both dark margined on both sides ; behind the costal streak, 

 at the end of the golden portion and before the apex, is another small 

 costal silvery streak, which is distinctly dark margined before by a straight 

 line, and faintly behind by an oblique one. Apical spot black, and 

 behind and adjoining it is a fan-shaped, dark brown spot, behind which 

 is a straight dark brown streak in the ciliae, extending to the apex. The 

 apical spot is margined before and on each side with brilliant, metallic, 

 silvery scales, as in splcndorifcrdla. 



At. ex. 2 lines or less. Same as in spleudorifcreUa, but this species is 

 slenderer than that. The first costal and the dorsal streaks are as in that 

 species, but there is much less golden in the apical half of the wing, and 

 much more blackish or dark brown. The apical spot aud adjoining fan- 

 shaped patch and apical streak are as in splendoriferella, but in splejidori- 

 ferella there is but one costal streak. It is, in fact, less like spUndoriferella 

 than any of the other species. The pupa case is nearly an ellipse, slightly 

 oval, golden yellow, marked with small brown dots. 



I was at first in doubt whether this might not be Clemens'" A. lucifluella, 

 which mines Hickory leaves. But I cannot reconcile it to the require- 

 ments of his description, which says that luciJIueHoi is larger than 

 splendor if erella,2in6. has three costal streaks. I have met with the larva of 

 liicifluella, but have not succeeded in raising it. \jx. Clemens met with 

 another mine in the leaves of the Hornbean, which he called A. asiryac- 

 foUella, but the maker of the mine is still unknov\'n. Possibly it may 

 prove to be this species. 



[Since the foregoing remarks were written, I have observed that the 

 microscopic hairs (vegetable) on the surface of the case of A. clla are 

 identical with those on the under surface of Hickory leaves, and this 

 tends to the conclusion that this is Clemens" lucifluella ; but other leaves 

 may have similar hairs. The fact that I can not recognise it in Dr. 

 Clemens' description is by no means conclusive, for my own first descrip- 

 tion is certainly defective, and the shades of coloring vary so with the 

 play of the light, that it is a very difficult species to describe satisfactorily.!'
