''Papilio forbesi'' is a butterfly of the family Papilionidae. It is endemic to Sumatra. ==Description== ''P. Forbesi'', Henley Grose Smith, Entomologist's Monthly Maqazine, xix., p. 234 (March, 1883) ; Forbes, " Naturalist's Wanderings," p. 275 (1885). Upperside. Dark brown, almost black, the margins between the nervures with lunular white spots ; very narrow on the anterior wing ; much broader on the posterior wing, which is without tails. Anterior wings with longitudinal rays on each side of the nervures, of light brown, extending from the middle to the exterior margin. Posterior wing with a row of three brownish-grey lunular spots between the median nervules, and a spot at the anal angle, above which is a row of three small faintly marked spots of same colour. Underside. Anterior wings rayed as above, but paler. Posterior wing with a longitudinal red spot at the base, divided by the precostal nervure, which is black, and a small red spot below the costal nervure ; a broad band of ochreous yellow with a row of black spots in the middle, extending across the wing between the median nervules, and a small spot of ochreous-yellow beyond ; a black spot at the top of the band next the anal angle ; three blue spots near the exterior margin from the costal nervure to the median nervule. " Exp. 4 inches. Hal). Bandang Agang, Sumatra (Forbes). In the Collection of Henley Grose Smith. "This species belongs to the Memnon group, in which, however, there is nothing which resembles it."(H. G. S.. in Entomologist's Monthly Mayazine,l.c.).Described from two male specimens, almost identical in colour and markings. It is, perhaps,most nearly allied to ''Papilio Lampsacus'', Boisd. The red spot at the base of the hind wings is not completely divided by the curved black stripe which runs up along the precostal nervure.〔Henley Grose-Smith and William Forsell Kirby,1887-1902 ''Rhopalocera exotica; being illustrations of new, rare, and unfigured species of butterflies''.London :Gurney & Jackson.〕 The wingspan is 90–100 mm. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Papilio forbesi」の詳細全文を読む スポンサード リンク
