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. G. 

 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.
