Dr. Boisduval attacks M. Godart for considering this the female 

 of T. evippe, Linnaeus ; it is, however, not improbable that it is only 

 a variety of that species, inasmuch as it chiefly differs from it in the 

 possession of a black dot at the end of the discoidal cell ; it cer- 

 tainly is the female of the A. evippe of Boisduval; the female described 

 by the latter author is not even nearly related to this species, but is 

 probably identical with, or nearly allied to, T. gavisa.

One of our female examples of T. arethusa is intermediate between 

 the figures of Drury and Cramer.

 This is probably the rarer form of T. arethusa ; the males of the 



two forms are almost identical.

 male, with broad carmine apical area ; underside with a well- 

 marked discal series of subocellate spots.

This variety has the basal area of the male less strongly suffused 

 with grey, and the under surface of the secondaries of a creamy 

 colour.
