Feniseca tarquinius is widely distributed over North America, 

 from Canada to Florida. It measures rather less than an inch 

 and a half across the wings. The male is dark brown, with an 

 irregular longitudinal tawny band on the fore-wings, marked 

 with a dark line interrupted towards the base. There is a 

 broad tawny patch in the middle of the hind-margin of the 

 hind-wings, marked with a sub marginal row of black dots. 

 The fore-wings of the female are tawny, irregularly bordered 

 with brown, and crossed by two interrupted longitudinal black 

 bands. The hind-wings are bordered with tawny, and marked 

 with a double row of black dots. The under side of the tore-

 reddish-yellow, with darker spots, slightly surrounded with 

 white. 



The larva is green, with white longitudinal lines ; it is ex- 

 clusively carnivorous, and feeds on aphides. Ants, which are 

 in the habit of milking the larvae of other Lycanida, attack 

 and destroy these. The pupa is greyish, the back darker and 

 tuberculated, the hinder extremity pointed and slightly curved.

 and form than any other of our Chrysophanides, the abdomen 

 being basally hunched, and laterally expanded, and the seg-
