ARISTOTELIA ARGENTIFERA, newr species. 

 AristoteUa (irgentlfcra Busck, Dyar's List Anier. Lep., No. 5583, 1903. 



Antenna^ .slightl}' serrate toward the tip, black, with silvery-white 

 annulation.s. Labial palpi, second joint light brown, with two incom- 

 plete white annulations; terminal joint blackish brown, with extreme 

 tip and three narrow annulations white. Face whitish, ting-ed with 

 brown; head and thorax light brown, intermixed with slate-colored 

 scales. Forewings clear, deep brown, ov^erlaid on costal half with dark, 

 blackish brown. From near base of costa is" an outwardl}^ directed 

 oblique white fascia, reaching nearly to dorsal margin, and edged and 

 continued by strongly metallic silvery and bluish iridescent scales. 

 At middle of wing is a costal white dash, continued downward and 

 slightly inward nearly to the dorsal edge by a fascia of metallic scales. 

 At beginning of costal cilia is a similar larger white dash, continued 

 obliquely inward and downward by a line of metallic scales. Between 

 the lirst and the second fascia is an additional smaller white costal 

 spot, edged by metallic scales, and at the extreme apex is an ill-defined 

 small group of white scales. From the very base of the wing out- 

 ward and downward is a thin line of iridescent and silvery white 

 scales, and single iridescent scales are found irregularly and sparsely 

 in the other part of the wing. Cilia whitish, mixed with brown. 

 Hindwings light silvery fuscous; cilia, with a golden-brown tint. 



Abdomen brown with each joint tipped with silvery white. Legs 

 blackish brown with silvery white bars and annulations; spurs silver}^ 

 white. 



Alar expanse.— 10.5 to 11.5 mm, 



Ilahitat. — San Francisco County. California. 



Type.—^o. 6350, U.S.N.M. 



Described from 10 well-preserved specimens collected in October, 

 probably by Mr. Koebele, judging from the elegant mounting. 



I found a single specimen of this species in the Museum of Com- 

 parative Zoology in Cambi'idge, labeled l)y Lord Walsingham 

 '"'' GclecMa argentlferaC^ which appropriate name I am pleased to 

 adopt. 



ARISTOTELIA COCKERELLA, new species.

Antennae dark brown with yellow annulations. Labial palpi yellow, 

 second joint sparsely sprinkled with black. Face, head, and thorax 

 light greenish yellow. Basal two-thirds of forewings light j^ellow, 

 concolorous with thorax; apical third dark purplish brown with a 

 slight touch of 3^ellow on costal edge before apex. The limit between 

 these two colors is oblique and sharply drawn, forming a straight line 

 from the beginning of costal cilia obliquely inward to apical two-fifths
