Front of the head green. Eyes dark brown, very large, and placed near
each other. Thorax green, having on each side two transverse yellow
stripes. Abdomen of the male blue, with small yellow indented marks on
the sides; that of the female yellow; the former having two little horny
substances like tails at the extremity, which are wanting in the female.
Wings reticulated and transparent; the middle of each being of a very
dark blue colour, occupying about a third part, and crossing them from
the anterior to the posterior edges, which by the reflection of white
