across the wings ; the fore-wings are arched, and not longer

 hind-wings. It is found at Rio Janeiro, but is not a very

Type, C. eurylochus (Cramer). 



The species of Caligo are large broad-winged insects resem- 

 bling Morpho, but they may be at once distinguished, not only 

 from Morpho, but from all other Butterflies, by the huge black 

 eye, with a bluish or whitish crescent in the middle, and a broad 

 yellow outer ring, which is placed on the under surface of each 

 hind-wing, a little below the middle. The wings are generally 

 dull blue or buff, with broad black borders, and one or two 

 have orange mai kings towards the tip of the fore-wings, or on 

 the hind-margin of the hind-wings.
