Tue breadth of the Idalia Butterfly is four inches 
and an eighth in extent ; the wings are of a deep 
rusty brown in the centre, with variously-shaped 
blotches of black, around which the whole are broadly 
bordered with black, and spotted with equidistant 
triangular white marks, with a row of these on the 
posterior margin; the lower wings are of an intense 
bluish black, with large, pale, cream-coloured, 
somewhat square-shaped spots; the margins are 
indented, and have a row of white crescent-shaped 
spots near their edges ; a streak of brown extends 
from the insertion of the wings to nearly their 
centre ; the head, eyes, and thorax, are of a burnt 
umber brown colour; the abdomen deep Ant- 
werp blue, and the sides provided with brown 
downy hairs. The under surface of the wings 
have silvery spots. 
This butterfly is a native of many parts of North 
America.
