Hab. Celebes, Borneo.
This insect, a female, is 5 lines larger than M. iridipennis; but I can point out no other distinction beyond a slight difference in the colour of the wings: the specimen from Borneo has a metallic bluish-green iridescence, the Celebes insect has a violet iridescence; notwithstanding which I am inclined to regard them as one species.
2. Mygnimia fumipennis. M. aurantiaco-rubra, alis obscure fuscis.
