182 EHOPALOCEEA. 



The first section of this genus is generally distributed throughout tropical America ; 

 the South- American portion of the second section is confined to the north-western 

 part of the continent; while the third is restricted to our region. Their colours 

 are to a great extent independent of those of other butterflies ; but this is hardly the 

 case with E. dione, the female of which resembles in pattern many other species of 

 butterflies.

There appear to be two forms of this butterfly found in Mexico and Central America 

 which occur together in Mexico and Guatemala ; whether they are always definitely 

 separable is perhaps an open question, as signs are not wanting showing that their 

 distinctive markings may ultimately prove to converge ; at the same time, with upwards 

 of eighty specimens before us we are still able to separate the two forms. Fortunately 

 we have paired specimens of both, so that we are able to assign the right females to 

 each. The males of M jethys may always be distinguished from that sex of E. albania 

 by the distinct longitudinal streak of black extending over the region of the median 

 nervure ; this is wholly wanting in the other form. The female has a well-defined 

 spot at the apical angle of the secondaries, usually absent, or at most very faintly 

 represented, in the female of E. albania ; these are the salient points of distinction. 



As a rule the colour of E. jethys is a deep orange ; but we have several Mexican 

 specimens which are of a clear yellow, and we have also transitional forms. In the 

 yellow specimens there is a tendency for the median band of the primaries to become 

 obsolete, but in the most extreme forms a black spot between the median branches 

 still remains. 



E. jethys was described by Boisduval from a male specimen from Mexico, whence we 

 have examples of both sexes, the female agreeing accurately with Felder's description 

 of E. cornelia. In Guatemala it occurs on both sides of the Cordillera up to an 

 elevation of about 4000 feet.
