THE GEOGRAPHICAL RACES OF TROIDES RHADAMANTUS (LUCAS) (LEPIDOPTERA: PAPILIONIDAE) OKANOMasao and OHKURAJozaburo Several’forms’ allied to Troides rhadamantzas have been described from the Philippines and Talaud lslands, Ndrthern Sulawesi: rhadamantus LucAs (1835)’ and nePhereus GRAy (1856) from the Philippines, hesiodus FRuHsToRFER (1911) from Mindoro,. bazilanicus FRuHsToRFER (1908) from Bazilan, belzanor’FRuHsTbRFER (1911) from Joro, Plateni STAuDIN.GER (1888) from Palawan, and doherty.i RippoN (1893) and vordermanni SNELLEN (1895) from/Talaud. lt is・very difficult problem to determine their taxonomic situation, ’ ≠獅п@opinions about the determination are divided amopg. different entomologists. JoRDAN (1909) placed nePhereus and ba2ila- nicus in symonymy with PaPilio rhadamantus, and regarded Plateni and dohertyi as subspecies of P. rhadamantus. ERuHsToRFER (1911) treated hesiodus, bazilanicus, belzanor, Plateni, and dohertyi as subspecieS of P. rhadamantus. BRyK (1929) enumerated all the forms as follows: TrOides rhadamantus.(=nePhereus); var.’Plateni, Var. ba2ilanii us, var. hesiodus, var. be12anor, and var. dohertyi (=vordermanni). D’ABRERA (1975) placed hesiodus, bazilanictzs, ’and belzanor in synonymy with T. rhadamantus, and restored Plateni and dohertyi to specific rank. ln this . paper we treat bazilanicqs, belzanor, ・Plateni, and dohertyi as the geographical races or the subspeeies. of T. rhadamantus. Before going further we wish to express ou; hearty ehanks to Mr. T..G. HowARTH and Prof. Dr. TL SHiR6zu for .their・ kindness rendered in various ways; thanks are also due to Mr. K. OKANo and ・Mr. Y.

There is considerable variation among individuals in the extent of black scaling on the golden area of the hindwing recto as shown in text-fig. 1, A-C: among 32 S we examined, 9 S as A, 178 as B, and 6 S as C. The golden area near the distal margin of the hindwing verso is not invaded by black scaling.
