Protosticta gracilis .

Exp. al. 62 millim.; long. corp. 51 millim. Male. Head black; labrum above yellow; thorax bronzy black on the sides, green in the middle above, in some lights, an oblique yellow stripe below the fore wings; the under surface, especially behind, and the legs yellow, the latter with long slender hairs; abdomen long and slender, thickened towards the extremity, bronzed above, the last three segments pale (probably blue or green in life); under surface with a long yellow spot at the base of the first 7 segments. Wings hyaline, with black nervures; pterostigma large, twice as long as broad, covering two cells, oblong, but the inner and upper angle truncated, making the upper side shorter than the lower; a double row iff cells beyond the pterostigma. Fore wings with 21- 22, and hind wings with 8 postnodal cells. Median and subnodal sectors rising just before and after the nodal cross-nervure respectively; the nodal sector rising 5 or 6 cells beyond, and the ultranodal one or two cells further. Trapezium regular, about twice as long as broad, its upper sector extending to the level of the origin of the nodal sector; its lower sector absent. Two basal postcostal nervures, the first halfway between the base and the first antenodal cross-nervure, the second just before the level of the second antenodal cross-nervure. Two cells between the trapezium and the first descending nervure. Upper anal appendages as long as the 9th segment, incurved, the lower ones shorter, but their exact structure not visible. Hal). Menado, Celebes {Wallace). The generic characters differ a little from those assigned to Protosticta simplicinervis, Selys (also from Celebes), which is not before me, and I have therefore included them in the description.
