 (See Proceedings, January, 1860, p. 11.)* 

 The diagnosis of this genus was made from two specimens 

 of A. splendoriferella. In insects so extremely small and 

 fragile, even when relaxed by moisture, it is no simple task 

 to make a correct diagnosis from a single examination. The 

 reader will therefore please correct in the January number of 

 the Proceedings as follows :f Labial palpi extremely short and 

 slender, much separated. Tongue naked and scarcely as 

 long as the anterior coxce. 



jflAflf- A. lucijiuella. Head silvery. Antenna? rather dark fuscous. 

 Fore-wings silvery from the base to the middle, and thence 

 to the tip dark fuscous varied with golden. Near the tip are 

 three short, costal silvery streaks adjacent to each other; the 

 first is longer than the others, with converging dark margins, 

 and a golden patch on its internal side; the second with 

 straight dark margins, and a golden patch beneath and 

 adjoining it; the third is unmargined, except by the external 

 margin of the second streak, which separates them. Opposite 

 the first costal streak is a dorsal, tapering streak of the same 

 hue, and placed in the dark-fuscous portion of the wing. 

 From the second golden spot to the middle of the hinder 

 margin is an oblique silvery streak, sometimes separated into 

 two spots. At the extreme apex is a deep black triangular 

 spot ; the cilia grayish, tinged with pale brownish. 



The larva maybe found in September and October, mining 

 the leaves of hickories. The head, first and second segments 

 are brownish, with a reddish tinge; body brownish-green, 

 with a dark green vascular line and three blackish dorsal 

 spots on the middle segments. Early in October the larva 

 cuts out an oval disk and enters the pupa state, to appear as 

 an imago early in June. The perfect insect is larger than 

 Splendoriferella.
