THE MELITvEA BUTTERFLIES. 287 



The wings and the feelers of this and the following species 

 are proportionally more elongated than in the Idalia and 

 Aphrodite butterflies. The Myrina begins to appear about 

 the last of May, and may be found till the end of June ; it

Argynnis Bellona, Fabricius. Bellona Butterfly. (Figs. 113, 114.) 



Wings tawny above, with two rows of black spots around

Expands from If to l T 9 g- inch.
