AMERICAN LEPIDOPTERA, 287 



On the same days I took about fifty Arfhemis, all except two or 

 three being males, and just from chrysalis. I have never known Ar- 

 themls so abundant in that locality. The variation among so many 

 was remarkable, particularly in the width of the white band and size 

 of the russet spots above and below; in half the specimens these spots 

 were wanting above, in others there were two or three and from that 

 up to a complete series of large rounded spots ; the color of under side 

 ran through all shades, from blackish to brown, cinnamon and russet. 

 LyciENA viOLACEA, Edw. (Proc. Ent. Soc. 186G). 



Female. Upper side uniform slate-color. Under side similar to male. 



This species was exeedingly abundant on the Kanawha in April and 

 May of the present year (1867), and I took at least one hundred fe- 

 males, all but six of which were as described above. These six were 

 of the more usual type of the female Lycsenidte, that is, blue, with a 

 broad black border to the hiud margins. 

 Hesperia Pilatka, n. sp. 



Male. Expands l^''^^ inch. Upper side. Primaries honey-yellow in 

 the disk, with a very broad, black hind margin, the edge of which is 

 irregular within, and with a slight sinus opposite the stigma; at the 

 base a few black scales along the nervures ; the stigma is narrow and 

 straight, but broken, the anterior half above the line of the other and 

 resting upon it at the fracture. 



Secondaries have the costal and hind margins as broadly edged with 

 blackish ; the disk more obscure, much covered with brown hairs, and 

 the nervules black. 



Under side of secondaries uniform brown, immaculate; of primaries 

 a shade lighter, with a ferruginous patch on the disk, inclining to yel- 

 low next hind margin ; a black patch at base joined to the stigma ; 

 inner margin deeper brown; legs brown; palpi soiled-white; antenna) 

 brown above, pale ferruginous below; club ferruginous. 



From one male, taken at St. Augustine, Florida. 



This distinct species is allied to //. Bidenta, judging from the plate 

 in Boisduval and LeConte, and the description of Godart given by 

 Morris, a species I have not yet seen. 

 Hesperia Nortonii, n. sp. 



Male. Expands ly^^ inch. Upper side uniform glossy brown ; pri- 

 maries have three minute semi-transparent spots on the costa near apex, 

 a similar spot at the extremity of the cell and another near the end of 

 the stigma; the stigma is long, convex without, while the inner edge 

 is nearly straight, giving it a crescent shape.
