Labial palpi, face, and head o-olden white; antennae white with 

 black annulations. Thorax pale golden. Forewings shining- white 

 with golden reflections, sometimes sutfused with pale golden; an out- 

 wardly oblique, somewhat curved coppery-golden fascia from base of 

 costa; another similarly colored on the middle of the wing is strongly 

 furcate at costa, and a third inwardly oblique fascia at apical third, 

 parallel with the outer fork of the second fascia, emits a lobe into the 

 apical part of the wing, sometimes connecting with the coppery -golden 

 apex. Hindwings dark gra}'. Forewings with viens 7 and 8 separate. 



Alar eXj^xmse. — 11-18 mm.

The American specimens, which, w^ithout hesitation, I refer to this 

 species, as Lord Walsingham and others have done before, average 

 slightl}" larger than the European specimens and the color of the head 

 and thorax is somewhat lighter than in the European series at my 

 connnand. 



Chambers recorded the species from Colorado. In the U, 8. National 

 Museum are, in addition to a good European series (Hofi'mann collec- 

 tion), specimens from California, determined by Lord Walsingham, 

 and a large series collected by Doctor Dyar on alder in British Colum- 

 bia; also specimens from Center Harbor, New Hampshire (Dyar), and 

 from Pecos, New Mexico (Cockerell).

Labial palpi, face, and head golden white; antennii? annulated 

 with brown. Thorax golden-white; patagina golden. Forewings 

 white sutfused with pale golden; a darker golden streak on the fold 

 from ))ase to a golden dorsal spot at basal third; an outwardly oblique 

 oolden streak from the middle of the dorsal edge reaches bevond the 

 middle of the wing and at tornus is a golden spot. Hindwings fuscous. 

 Forewings with veins 7 and 8 separate.

This striking species was tirst recorded from America by the late 

 Prof. C. V. Riley. In the U. S. National Museum are specimens from 

 British Columbia (Dyar) and from Seattle, Washington (Kincaid), 

 which I can not ditierentiate from the European series of tliis species.
