wing and patagium light steel-gray; before the middle of the wing is a 

 straight perpendicular light steel-gray fascia, bordered on both sides 

 with black scales: apical third of the wing light steel-gray, edged 

 basally with a narrow line of black scales ; the apical metallic gray 

 color reaches along the dorsal edge to the middle of the wing. First

 Alar expanse, 8.5 mm 



Habitat Williams, Arizona: TT. S. Berber, collector. 



Type U. S. National Museum No. 12270. 



A remarkably fine species, typical of the genus in oral and 

 pterogostic characters, but at once distinguished from all de- 

 scribed American species of the genus by its complete trans- 

 verse fascia.

Lord Walsingham and Mr. Durrant have already published :;: 

 the generic synonomy indicated above, as worked out during 

 m,y stay at Merton Hall last year. By fixing chenopodiella 

 Httbner as type of Sc\thris, .Irotrura Walsingham and 

 Colinita Busck became synonyms of that genus. The specific 

 identity of Arotrnra eburnea and Holcocera arirjonella Kearfott 

 did not occur to me in 1 ( ^07, but is at once established by the 

 examination of the types.
