Show 1880.] ON NEW PAPUAN BUTTERFLIES. 613 costa and extending within the transverse band to nearly the apical angle of secondaries and gradually becoming narrower. 3Ius. nostr. This species is much like the last, but differs in having the outer half ot both wings black, curtailing to a much greater extent the reddish-fulvous of the basal portion of the wings. The blue spots on the primaries, instead of forming a distinct band across the wing, form the lower end of the apical series of white spots which in D. dascon are only indicated near the costal margin. The female is not unlike that of D. comriei, but is smaller, has a more restricted white patch on the primaries, and the base of the wings is of a richer fulvous tint. PIERIS ORNYTION, sp. nov. (Plate LVI. fig. 5.) 3 . Exp. 2-5 in. Upper surface white, apex of primaries, extending nearly to the anal angle, and cilia of secondaries, black : beneath, apical third of primaries black, tipped with yellow, the rest white; secondaries black, with a strong crimson dash extending from the base some distance along the costal region, and a fine submarginal line of the same colour (in some specimens almost obsolete) commencing shortly beyond this and running to the anal angle. 5 like 3, but costa and apical half of primaries black, secondaries greyish, with broad black outer margin ; beneath, the black is broader than in the male, and the submarginal red line of the secondaries is but faintly indicated. Mus. nostr. PAPILIO GOLDIEI, sp nov. (Plate LVI. fig. 6.) 2 • Exp. 3*5 in. Wings dusky black, primaries beneath the median nervure (and also above, occupying nearly half the cell) creamy-white, divided into four long stripes by the median branches, which are edged with black ; a row of submarginal whitish spots commencing near the end of the cell extends to the anal angle; within this are four subapical irregular-shaped spots of the same colour ; secondaries have a broad creamy patch, extending from the basal half of the inner margin to beyond the cell, divided by the nervules, which are strongly marked, and a submarginal row of six white spots; beneath as above, but with four small white spots (one on the primaries, three on the secondaries) at the base of the wings. Mus. nostr. Mr. Goldie has sent four examples of this insect, all of which are females : three of these are precisely similar, and correspond to the description given above; in the fourth (fig. 6) the black extends over the greater portion of the wings, the whitish markings being reduced to a very narrow compass. In the absence of more specimens, we are inclined to regard this as merely a dark variety. In form the species resembles Papilio leucothoe of Westwood, from |
