Aehaja is described on same page, and the author says : " This species 

 I received also from Mr. Hoffman, \n\\o fou?id it associated with Dcedahts." 

 The number of specimens examined is not stated. But both sexes of 

 Aehaja were described as alike in color. As the specimens taken by the 

 Geological Survey almost always came in bad condition, especially with 

 the bodies squeezed as flat as a knife blade, it is not surprising that Dr. 

 Behr mistook some of these for males. That his Aehaja agrees with Mr. 

 Wright's females of Dcedahts, is evident from a type specimen which Dr. 

 Behr sent me at about the date of his description, and which still stands 

 in my collection with his label. 



This is the same species also which Dr. Boisduval described, Lep. de 

 la. Cal., 48, i86g, as Rufescens. In my Catalogue of 1877, Dcedalus is 

 set down as a syn. of Icaroides, while Aehaja is given as a dimorphic form 

 of the female of Scepiolus, Rufescens being a syn. of Aehaja. I seem to 

 have overlooked the fact that Boisduval described a blue male with the 

 brown female, or russet female, as the text says, and this word describes 

 the color, perhaps, better than any other. Boisduval certainly must 

 have been misinformed as to the locaUty, as he says " it lives on the 

 plains in the interior, in May." Whereas the species is Alpine, and would 

 be taken in midsummer. It is allied to Scepiolus and Icaroides, both of 

 which are found in lower elevations. 



The synonymy should then be : — 

 DAEDALUS, Behr. 



% Aehaja, Behr. 

 ^ % Rufescens, Bois. 

 Although I am not aware that I have ever before seen an example of 

 Dcedalus $ , I have had several of the $ , or Aehaja, but cannot state 

 from what particular localities they came. 



As the descriptions of both Behr and Boisduval are very short and are 

 scarcely distinctive, and besides are not accessible to most of our collec- 

 tors, I append my own descriptions of both sexes of this Lyccena.
