I found one specimen of this species on the foliage of 
a low tree, at Caripi, near Para. Unfortunately it was 
not reserved for my private collection, and I have drawn 
up the above diagnosis from the type specimen in the 
British Museum, which was found by Mr. J. P. Gr. 
Smith, also at Caripi.

Two female examples only of this beautiful species

dor, entirely of a beautiful greenish-blue colour, and 
rather more coarsely sculptured.
