 Syn. hamamelis Smith's List Lep. Bor. Am., 1903, No. 6844. 



Face and palpi whitish. Antennae whitish ocherous, annulate with dark brown. 

 Tuft reddish orange. 



Thorax and forewings deep reddish orange. An oblique white streak from the 

 inner angle to the fold is black margined externally. There are two straight, 

 oblique, parallel, silvery bands black margined externally, the first at the basal 

 fourth, and the second at the middle of the wing length. At the beginning of 

 the costal cilia is a silvery spot, black margined externally. Opposite it is a long, 

 very oblique dorsal streak, parallel to the termen, also black margined behind, 

 and uniting in the apex of the wing with a short apical streak, dark margined 

 at its apex and above and below. Marginal line in the cilia of the wing color. 

 Cilia reddish, becoming gray at the tornus. Expanse 7 mm. 



Hindwings and cilia reddish gray. Abdomen dark gray above, ocherous gray 

 beneath. Legs pale brownish red, tarsal joints white, tipped with black. 



This species is distributed throughout the Atlantic States wherever 

 the food plant, Hamamelis Virginiana L. (witch hazel), occurs. The 

 mine is a whitish blotch, sometimes almost circular; the pupa of the 

 summer brood is formed beneath a flat silken cocoon. 



Although it is very closely related to aceriella, it may be separa- 

 ted from that species by the deeper and more reddish color of the 

 tuft and wings, and by the more distinct marginal line in the cilia. 

 The hind tarsi of hamameliella are also very distinctly tipped with 

 black, whereas, in aceriella, they are either faintly blackish tipped 

 or entirely pure white. The oblique dorsal streak, which has been 

 used to separate hamameliella from aceriella, cannot be relied upon, 

 as this streak is often as oblique in aceriella as in hamameliella.

 "Head silvery white. Antennae fuscous, slightly annulated with white; basal 

 joint pale saffron. Forewings pale saffron, with two silvery white moderately 

 broad bands, black margined externally, one near the base, and the other on the 

 middle of the wing, and both somewhat oblique; cilia of the general hue. Hind 

 wings dark grayish, cilia the same. 



"The larva belongs to the second larval group of this genus, but the body is 

 much more contracted than that of any other larva I have seen. Its form is 

 almost that of a flattened ovoid, the rings separated by the deep incisions, and 

 each forming in the sides a projecting mammilla.
