The last one is proposed to be a new genus. A new subspecies of facoon amrita is also described here. The holotypes are to be preserved in the Osaka Museum of Natural History. Deramas ikedai II. Hayashi, sp,nov. (Figs.1-2,9-11) 6. Upperside forewing alrnost wholly black. A faint streak of sparse bluish green scales in space lb, a few scales in space la. Hindwing black exceptfor faint bluish green streaks in spaces 1,b-4. Ciliachequered. Underside dark brown,with pale-eclged darker brown post-discal lines, A faint black submarginal spot in space lb on forewing, and an orange-crowned black submarginal spot in space lb on hindwing, Forewing length 12mm. MaLe genitalia: Valvae separated into three processes; the upper process or ampulla longer, with serrated tip; the lower process or harpe short, with blunt tip; the costal process dentated, which is joinedto the opposite valva at its proxal end by a membrane. Phallus large and stout, strongly bent ventrally, 9.Unknown. Distributien: Mindanao Holotype S, Mt. Apo, Mindanao, February, 1978,K. Nakarnoto leg. The present new species is apparently silar to Deranias nigrescens Eliot frorn Celebes, but upperside greenish scales are rnuch fainter ancl a subtornal orange spot on underside hindwing present in this new species, while in nigrescens no orange subtornal spot at all. The rnale genitalia in th:,s new species are quite different from those of D. nigrescens, and closely related to those of D. antynax Eliot, but is dissilar to those in the following respects: 1) valva: In ant.vnax, harpe very long, but short in the present new species. 2) Phallus: Strongly bent ventrally, whereas slnuated in antynax, The specific name of this new species is dedicuted to Mr. Masahire Ikeda, who is intate with Mr, I<. Nakamoto and always showing h great kindness, IVdrathura nakarnotoi H. Hayashi, sp, nov, (Figs.3-4)?, Upperside forewing pale blue, whitish in discalarea. Black spots in spaces4 and 5. Borcler 5mrn at apek to 2mm at dorsum. I-Iindwing uniform pale blue. Border narrower than in forewing. Underside pale brown. Markings rather conspicuously white-edged. Forcwing no spot in space 11. A. costal spot in space 10, A discal spot in space 7 on right wing. Discal spots in spaces 4 to 6 broader than those in spaces 2aiid 3. Hindwing with a white streak at base of space8. Spots in spaces 6 ancl 7 in line. Lower part end-cel] spot expanded eutwardly and central 6pot in space lb elongated, Discal band clislocated at vein 2. Tornal blue scales sparse in spaces lb and 2, Originally it had probably a tail at vein 2 on hindwing. Forewing length 22mm, S. Unknown, Distrlbution: ll{indanao Holotype 9, Mt, Apo, Mindanao, February, 1978, K, Nakamoto leg.

3 The LepidopterologicalSociety Society of Japan 166 utlva TY6 TO GA (Trans,Lep.Soc. Jap,) Vol.29,No, This species is described with some hesitatlon,since represented by a single female. Judging from markings on underside,it falls in anthelus group of Ndrath"ra. A spot at base oi space 10 on underside of right wing is vestigial, and there is no such a spot on left wing, So I can not determine which one is proper to this species, Anyway this species isvery unique, and dees not agree with any species in anthelus group ans the related groups of 2Varatht{ra,According to the personal comnication of Lt. Col, J. N. Eliot, he has seen nothlng like this female, I name this new species after Mr. Kazuya Nakamoto who collected the specen, ELIOTIA H. Hayashi, gen. nov. Type-species: Eliotiamioae H. Hayashi, sp, nov. Nearest to Charana Nic6ville, 189e, but differingin the following characters ; Male with a srnall greyish sexual brancloverlying an area around the origin of vein 7 en upperside hindwing. A long black hair tuft along dorsum on underside forewing (withoutsuch secondary sexual charactcrs in Charana), The genus is dedicated to Lt, Col, J, N. Eliot in gratltude of his outstanding kinclnesses and in recognition of his suggestion to erect the genus. Eliotia mioae H. Hayashi, sp, nov, (Figs.5-6, 12-15) a. Upperside forewing deep shining blue, slightly tinged with purple, Black border broad, Hindwlng ground colour as in forewing. A greyish black brand overlying an area around the orlgin of vein 7, Underside greyish white. Post-discal bands broad with dark brown, A long black hair tuft along clorsumon forewing. An orange crown in spaces lb-2prominent, 2 tails at veins lb and 2, Ferewing length 19mm. Male genitalia: Juxta V-shaped. Valvae long, smoothly bent dorso-outwardly and tapered strongly towards apex. Phallus very long, slencler and curving dorsally,two cornutipresent, one long, the other short. 9. Unknown, Distribution : Mindanao Holotype e, Mt. Apo, Mindanao, February, 1978,K. Nakamoto leg. Paratype 6, Mt, Apo, Minclanao, February, 1978, K. Nakamoto leg. The present new species resembles Charana mandarina chotaroi H. Hayashi from Mindanao, but is easily distinguishable from it in the following respects: 1) Upperside ground colour deep shining blue, but shining greenish blue and no purple reflection in chotaroi, 2) Hindwing sex patch ch srnaller than that of chotaroi. 3) Underside ground colour greyish white, while chrome yellow in chotaroi. In the male genitalia, the present new species is quite different from chotaroi in the shapes of dorsum, valvae and phallus. Jacoona amrita toshikoae H. Hayashi, ssp. nov, (Figs,7-8, 16-19) S. Upperside forewing veins 11 and 12 free, veins 8 present, vein 7 ends on the termen. Ground colour paler than forewing, costal area broadly sparsed with greylsh sealing. A largeblack circular brand on the base of vein 7. Tails at veins lb and 2, the former longer than the latter, Underside ground colour white. Forewing apical area slightly ochreous brown, A black circu!ar brand on the basal a-third of space lb with long white hair tuft, Black post-discal and submarginal stripes in spaces la, lb and 2, and an obscure black submarginal stripe in space 3 on hindwing. Forewing length 19mm, Male genitalia : JuxtaV-shaped. Valvae moderate]y large,bent dorso-interiorly and slightly becorning narrow towards apex which is concaved minutely. Phallus steut, aedeagus strongly concave laterally,ventral surface rninutely serrate, a pair of cornuti present, 9, Unknown. Distributlon: Mindanao IIolotype as, Mt, Apo, Mtndanao, February, 1978, K, NakaTnoto leg.
