E. creusa L. (= thelebas Cr., irus Cr., ganymede Dbl.) (12 i) is the oldest and largest species known. North Australia, Fiji Islands, New Guinea, Celebes, New Hebrides, Pelau and many of the smaller South-Sea Islands.
The anterior 3 segments are deep blue, the remainder of the abdomen dark blood-red; all segments finely margined with black. Abdomen beneath from the 3rd segment on clear scarlet throughout. Specimens from Ceram and North-Australia have the first abdominal segment occasionally blackish. Looking at them from the side, the hyaline spots of the wings are distinctly blue-green. Seems to be very common in some places.
