Papilio toboroi

P. toboroi Ribbe (38 c). Whilst in laglaizei almost the whole upper surface of the body and also the sides of the abdomen are blue-grey, toboroi has an entirely black body without any markings. Upper surface of the wings dark blue, with a slight oily gloss; the median band of both wings narrow, the part placed in the cell of the forewing is commonly diffuse and is always at a distance from the apex of the cell; on the hindwing a pale yellow anal spot, the tail entirely black-blue. The under surface in contrast to laglaizei for the most part black; in the forewing a submarginal band, which is anteriorly broad and greyish yellow, posteriorly narrow and bluish, and before the middle a more or less indistinct narrow blue band; on the hindwing a large basal area and a broad submarginal band are grey-yellow, and the black central area is more or less broken up into large patches, the orange-coloured spot before the hindmargin paler than in laglaizei. The female as in laglaizei quite similar to the male; on the upper surface of the hindwing it has from the 3. radial backwards an irregular narrow grey-blue submarginal band, which in the male is only indicated. — Bougainville, Solomon Islands; in the interior of the island, a few miles from the coast, the butterfly is rather common in low situations. …
