Species of the Genus Liriienitis. 465 



VII. Troilus Group. 



Allied to the highly mimetic Anchisiades Group, with 

 gregarious larvse. 



Contains only two species, of which one is mimetic and 

 the other probably non - mimetic, although incipient 

 mimicry is possible on the under surface. 



85 a. P. troilus troilus, L. 



From Georgia to Canada : westward to Texas and the 

 Mississippi plains : north-westward to N.W, territory of 

 Canada. 



85 b. P. troilus texamis, Ehrm. 



Florida, in spite of the name. Probably a more primitive 

 form in which the mimetic resemblance is less advanced 

 than in 85 a. 



86 a. P. palaniedes j^alamedes, Drury. 



Florida to Philadelphia, and westward to Mississippi 

 plains. 



86 b. P. palamedes leontis, Rothsch. and Jord. 

 A small form. Monterey, Mexico. 



Limenitis astyanax. — The distribution is thus given by 

 Scudder : — " It ranges from the Atlantic westward to the 

 Mississippi Valley, and from the Gulf of Mexico northward 

 to about the 43rd parallel of latitude." A closely allied 

 species or more probably a form of the same species is 

 recorded by Godman and Salvin from Mexico. 



Argynnis (Semnopsyche) diana, Or. — Scudder describes 

 the distribution of this species as follows : — " An inhabi- 

 tant of the hilly country of the south, following the 

 Alleghanies, and a comparatively narrow belt westward 

 at about the 38th parallel of latitude." How far westward 

 it extends is unknown (p. 1801.) 



The account given above shows that there is a very 

 close coincidence between the distributional areas of the 

 six species. When the area is comparatively restricted, as 

 in the case of A. diana, it is still, as Scudder points out, 

 altogether included within that of the species which its 

 female most closely resembles, viz. Limenitis astyanax.
