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 
reappears again in August and September. 
Argynnis Bellona, Fabricius. Bellona Butterfly. (Figs. 1 13, 1 14.) 
Wings tawny above, with two rows of black spots around

wings beneath, and under side of the hind wings, brownish,

latter, which are variegated with dark brown lines and spots. 
Expands from If to lA inch. 
Very closely resembles the Myrina in form and color of 
the upper surface of the wings, but is easily distinguished 
from it by the want of the silvery spots beneath. It is found 
on flowers in the latter part of July.

the hind wings is usually checkered with various colors, but 
not ornamented with silvery or pearly spots. Their cater- 
pillars arc very different, being covered with blunt tubercles

various kinds of plantain. The chrysalids are of the same
