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

 than the hind-wings, which are very broad. In colour 

 it is dark brown, with a connected row of pale sulphur-yellow 

 spots on the fore-wings, and a very broad orange border to the 

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

 common insect. 



The largest species of the Sub-family belong to the 



GENUS CALIGO.

 Diurn. Lep., p. 340 (1851); Schatz, Exot. Schmett, ii., 

 p. 193(1889). 



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.
