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.
