This beautiful little insect is not unlike the pre- 
ceding both in its form and colours. It belongs to 
a section of Polyommatus, in which the upper wings 
of the male are marked with an orbicular spot, of a 
cottony appearance, and frequently a good deal im- 
pressed. The expansion of the wings does not 
exceed an inch and a half. The colour of the surface 
is brilliant blue, the costa and outer margin of the 
wings black, and the disk of each marked with two 
ferruginous points in the male. Beneath, the colour 
is likewise green, richly glossed with golden yellow, 
the anterior portion of the under wings transversely 
streaked with narrow black marks. The tails are 
wholly black. 
All the examples hitherto brought to Europe seem 
to be from Surinam.
