ANTEOS. 149 



This species may be at once distinguished from A. mcerula by the colouring of the 

 upper surface of the wings, which instead of being of a clear lemon-yellow is chalky 

 white with a distinct orange patch extending from about the middle of the costa over 

 the distal half of the cell. In our country its range is very similar to that of A. mcerula, 

 but in South America it extends far beyond Colombia, and is found in Bolivia and 

 Eastern Brazil. Curiously enough neither of these species, nor indeed any member of 

 the allied genera, are found in the Amazons valley. 



All South-American specimens, with hardly an exception, have the orange spot of 

 the primaries of a rather more lemon tint.

The female of A. mcerula varies as to its colour ; some closely resemble the male, 

 others are of a dull orange, others again are drab. Some of these again have the apex 

 of the primaries, and the outer border as well as the ends of the nervures, fuscous. 

 This variation, we believe, has given rise to the supposition that there is more than one 

 species of this form, and we believe that Bhodocera gueneeana of Boisduval 6 was based 

 upon a yellow female of A. mcerula, in which the glandular patch of scales on the 

 secondaries is absent. That Boisduval was at fault respecting the sexes of this species 

 is shown by his remark in his Lepidoptera of Guatemala, in which he suggests that 

 A. clorinde may be the female of his Rhodocera lacordairei. A. mcerula is common 

 throughout the whole of our region up to an elevation of from 4000 to 5000 feet in 

 the mountains ; in South America we only know of its occurrence in Colombia.
