the base by a strong black bar, a terminal line of black dots between the veins, 

 and a suffusion of black powdering tending to produce a faint terminal band, 

 fringe white. 



Expanse: about 38 mm. 



The present species is closely related to A. nchardsoni but pre- 

 sents an entirely different habitus, is larger, lacks all trace of orange 

 and ochreous scaling, while the whole appearance of the primaries is 

 more suffused and less contrasty; beneath, the strong black bar. on 

 the secondaries, connecting the discal spot with the wing base is only 

 faintly indicated on some males of richardsoni. 



A single specimen has been in the Barnes Collection for many 

 years. Mr. Engelhardt captured another specimen, which he gave to 

 the authors. 



Type localities and number and sexes of types: Holotype 5 , Bullion 

 Peak, Hall Valley, Colo., 13,000 ft., 30-VIII-22 (George P. Engelhardt) ; Para- 

 type, 9 , "Colo. Bruce", probably taken by Barnes and Bruce on Bullion Peak. 



Anarta lagganata sp. nov. 



Head and palpi dull smoky-brown with an admixture of some white. 

 Thorax dull smoky-brown. Abdomen dull smoky-brown paler toward the tip. 

 Primaries: dull smoky-brown; basal line obsolete; t. a. line obsolescent, visible 

 as a slightly darker, outwardly oblique shade ; orbicular practically obsolete ; 

 claviform obsolete; reniform obsolescent, visible as a darker blotch at the end 

 of the cell ; t. p. line not well defined, outwardly oblique from costa to about 

 vein 6, slightly excurved around cell, thence nearly parallel with the outer mar- 

 gin to the inner edge of the wing; terminal line obsolescent; fringe concolorous 

 with the primary. Secondaries : disc white ; a broad smoky-brown terminal 

 band ; considerable smoky-brown scaling on the basal area and along the inner 

 margin ; some smoky-brown scaling on the veins ; discal dot, distinct, large, 

 erect, elongate, blackish-brown ; fringe smoky-brown at the extreme base, else 

 white. Beneath : white ; the primary marked by smoky-brown along the costal 

 and outer margins and with some smoky-brown scattered suffusion over the 

 disc, reniform showing through, marked by blackish-brown, fringe as on upper 

 side; the secondary white with scattered smoky-brown suffusion mainly on the 

 basal area, discal spot, terminal band, and fringe as on upper side. 



Expanse: 9, 32 mm.; $, 28 mm. 



The present species is tentatively placed in the genus Anarta 

 because the eyes are somewhat constricted, but they are not as much 

 constricted as in many species of Anarta, being less than twice as long 

 as wide. It is not at all unlikely that further specimens may show 

 that the insect is more closely related to some species of Lasiestra,
