162 EHOPALOCEEA. 



of both sexes ; they were doubtless individuals of one brood, and exhibit some variation, 

 both as to the sinuations of the inner edge of the black border of the primaries and the 

 extent to which the black outer border of the secondaries is developed. Mr. Smith 

 says that these pupae when living resembled the young undeveloped leaves of the plant 

 to which they were attached. 



We have figured specimens taken at Cordova, Mexico. 



b. Outer margin of secondaries rounded. 



c'. Subcostal branch of secondaries emitted close to the end of the cell. 



a". Submedian area of primaries of the male immaculate. 



a"'. Wings yellow or orange.

We have described specimens from the State of Guerrero, which on an average have 

 the dark border on both wings rather wide, but the difference is unimportant ; Costa 

 Rican specimens have the narrowest border, but can almost be matched by others from 

 the State of Vera Cruz. By some authors this species is supposed to be Papilio 

 thymetus of Fabricius ; but, as Menetries, when describing T. euterpe, long ago pointed 

 out, Fabricius's description is altogether too vague to be recognized with any certainty. 

 T. lisa of Boisduval and Leconte was proposed for the North-American insect ; but as 

 the Antillean and North- American insects appear to be absolutely conspecific, T. euterpe, 

 which was founded on Haitian specimens, must be used for it. In our country it 

 cannot be called a common species, though Mr. Smith's recent collection from the State 

 of Guerrero has supplied us with a fair number of specimens. In Guatemala we only 

 met with it in the highlands in the neighbourhood of Duenas.
