46 Psyche [April 



of posterior half blackish; hase shaded with olive-brown; apical 

 area marked nearly as in the typical form except that the sub- 

 marginal line is broader and more suffused; posterior half showing 

 an absence of the black bars found in typical virginiensis except 

 for a slight trace in the cubituSj cell near a submarginal white spot 

 usually found in the typical form. Secondaries : Ground color as 

 in primaries; submarginal row of blue eyelike spots represented 

 by a row of small indistinct white blotches which run into a suffu- 

 sion of white toward the anterior margin; exteriorly without the 

 submarginal black line found in typical virginiensis; fringes as in 

 typical form. 



Under side. Primaries: ground color whitish with the olive- 

 brown markings of virginiensis much reduced; disk pale apricot- 

 orange, pink in typical form, showing a white spot exteriorly and 

 wanting the black bars of the typical form; base with a double 

 black mark; costa with two black bars, as in virginiensis. Second- 

 aries : ground color nearly white ; a basal band and two bars on the 

 cell approximate anteriorly, one medial, the other apical, blackish, 

 veined with white ; anal area delicately shaded with blackish scales ; 

 submarginal eyelike spots characteristic of virginiensis much re- 

 duced, the anterior almost obliterated; subapical black line heavier 

 than in typical forms ; other markings found in virginiensis absent. 

 Described from one male taken by Mr. J. A. Kusche in Golden 

 Gate Park, San Francisco, California, November 11, 1911. Type 

 in collection of the California Academy of Sciences. Named for 

 the Ahwashtee tribe of Indians formerly inhabiting the peninsula 

 of San Francisco. 



This variation of V. virginiensis corresponds with the form 

 muelleri of Vanessa caryce in the markings of the upper surface, 

 while beneath, by its Avhite color, it approaches Vanessa cardui 

 elymi Eamb.^ In the type specimen there is a slight folding of 

 the primaries making the outer margin appear to be too deeply 

 notched below the apex. 



• This form is quite distinct from var. fulva Dodge and from tlie aberration 

 mentioned by Mr. H. M. Simms in Entomological News, XXV, p. 33, 1914.
