NO. 1506. REVISION OF MOTH GENUS ARGYRESTHIA—BUSCK. 17 



Hindwings li^ht ocherous gray. Veins T and 8 in the forewings 

 stalked. 



Alar expanse. — 1(> mm. 



Hah itat. — Texas . 



The species is nearest A. j)ed)n<))della Chambers, but differs from it 

 by its ocherous coloration and is easily recognized by the brown trans- 

 verse striation. 



The types are in the Museum ot" Comparative Zoolog}^ and in Lord 

 Walsingham's collection. In U. S. National Museum is an identical 

 specimen, which I have compared in both these places and which I 

 believe belongs to the original type series. 



ARGYRESTHIA ALTISSIMELLA Chambers. 



Argyredltia aUixgimclla Chambers, Bull. U. S. Geol. Surv., Ill, 1877, pp. 130, 147; 

 IV, 1878, p. 130.— Dyar, Bull. 52, U. S. Nat. Mus., 1903, No. 6454. 



I quote Chambers'" description: 



Of a leaden hue, except that the vertex is whitish, the antennfe annulated with 

 white; the palpi are a little darker than the general hue, except the under surface 

 of the second joint, which is whitish. Cilia paler than the wings. Expanse of wings 

 scant 6 lines (about 12 mm. ). In some lights the forewings appear silvery or pale 

 golden. Taken in July among dwarf willows on the side of Mount Elbert, Colorado. 

 Altitude 11,000 feet. 



This species is unknown to me except from the unique type in the 

 Museum of Comparative Zoology, on which 1 made the following note 

 in October, 1902: 



Type No. 1412, unique, labeled Colorado; in rubbed condition. Probably a true 

 Argyrestlda, but different from any known to me; forewings, which are much rubbed, 

 appear to have been uniformly golden fuscous, with strong metallic reflexions. 



Closer study of this type is required, but if, as I believe, it belongs to 

 the present genus, the species should be easily recognized when met 

 with.

Palpi, face, and head yellowish-white; antenn^y annulated with dark

 dark purplish-brown with dorsal [)art to tornus white; on the middle 

 of the dorsal edge is an outwardly oblique blackish-brown streak, 

 which loses itself in the dark costal part. Costal edge is strigulated 

 with yellowish white, and shortl}^ before apex is a larger white costal 

 dash. Apical cilia blackish-brown; dorsal cilia ocherous fuscous.
