Because the characteristics ofthe specimens from the Malay peninsula and Sumatra which we recently obtained are different from those of the Javanese specimens, the trgnis complex should be treated as two spocies, E agnis and E tinna, as shewn by Fruhstorfer (1906, 1913).

Introduction According to Tsukada (1991), Euthalia agnis (Snellen van Vollenhoven, 1862) has been recorded from the Malay peninsula, Borneo, Sumatra and Java, and is a rare species in any locality. Recently some male specimens of the agnis complex similar to Bornean tinna Fruhstorfer, 1906 (hereafter referred to a tinna-type) were obtained from North and West Sumatra, and these were different from a Sumatran subspecies moclesta Fruhstorfer, 1906 known before, Yokochi, one of the authors, preserves two males from the Malay peninsula: one is the tinna-type from S. Thailand, and the other from Cameron Highlands in Malaysia is similar to Javanese agnts (hereafter referred to an agnts-type). Therefore, beth types are sympatrically distributed in Sumatra and the Malay peninsula, We call the agnis-type and the tihna-type the agnis complex for sake ofconyenience in this paper, and revise here the classification of this complex on the basis of research en the type series preserved in The Museum National d'Histoire Naturalle Entomologie in Paris (MNHN), The Nationaal Naturhistorische Museum in Leiden (RMNH), The Natural History Museum in London (BMNH) and The Department of Zoology of the National University of Singapore (NUS).

L.: Kinabalu, N, Borneo) Descriptions of how the agnis complex has been treated taxonomically are as fbl!ows (refer to the synonymic list). I. Snellen van Vollenhoven (l862) Adohas agnis Snellen van Vol]enhoven, 1862 Snellen van Vollenhoven (1862) describe(i crgnis from Java as the first taxon of this complex. A female was figured in the original description, but the number of specimens in the type series is unknown. Its type series is preserved in RMNH, and we examined them. The designation of the 1ectotype has not been done. 2, Fruhstorfer (1906) Fruhstorfer described tihna and its two subspecies and one subspecies of agnis in 1906. This shows that he already recognized two species in this complex. 1) Euthaha tinna Fruhstorfer, 1906 Described based en two males and one female from Mt Kinabalu in North Borneo. Male and female were figured in the original description. The type series is preserved in MNHN, and of the type series we designate one male as 1ectotype here (Figs 13-14).

A female was figured in the original description, and it is clearly a tihna-type, A female of the type series is preserved in MNHN, but the other three males have not been located. We designate one female as lectotype here (Figs 21-22), Lectotype \, here'designated [exainined], labeled "Type (Red)ltinna agnijZ)rmis Fruhst./Sumatra, Deli, ex coll.

The paper says that the holotype is in The Singapore Museum (all the materials there were transported to NUS in 1957), but we cannot find it. It was neither found in BMNH nor MNHN, 4) Euthaha agnis modesta Fruhstorfer, 1906 Described based on three females from Battak Mts irt Nerth Sumatra. They were not figured in the original description. The type specimens are clearly the agnis-type and preserved in MNHN, and we designate one female as lectotype here (Figs 7-8).

We failed to find in the map of Sumatra, but Fruhstorfer (1904) describes Euthaha adonia sumanana based on one male from Montes "Deli, Battak, and the holotype is labeled Sumatra". ･Therefore, Deli is located in the Battak NII-Electronic Library Service The LepidopterologicalSocietyLepidopterological Society of Japan Euthaha agnis and Euthatia tinna, Two Distinct Species 21 Mts, 3. Fruhstorfer (1913) Euthaha agnis (Snellen van Vollenhoven, l862)' ssp. agnis (W. Java) ssp. modasta (N.Sumatra) Euthaha tinna Fruhstorfer, 1906 ssp. tinna (N, Borneo) ssp. trgnCt?)uais (N. Sumatra) ssp. paupera (the Malay peninsula) Fruhstorfer (1913) again treated this complex as tw6 species in Seitz vol. 9 on the basis of the presence ofboth species in Sumatra. And, in pl. 129, rovy b, he showed the figure ofthe male of agnijZ)nnis deseribed in 1906. 4. Corbet (1941) Euthaha agnts: Corbet, 1941 Corbet (1941) ¢ ompared agnis (Java) to tinna (Borneo), and he thotight they were the same specles, 5, Corbet (1945) Euthaha crgnis modesta: Corbet, t945 Corbet (1945) showed modesta as a subspecies of Euthaha crgnis. No figure was shown, but the male genitalia were presented. 6. Fleming (1975, 1983) ･ Euthaha agnts paupera: Fleming, 1975 Euthaha agnts paupeTzz: Fleming, 1983 Fleming (1975, 1983) showed paupera from the Malay peninsula as a subspecies of Euthalia crgnts. Male and female were presented, and the male was the tinna-type and the female was the agnis-type, 7. D'Abrera (1985) Euthaha agnis paupera: D'AbTera, 1985 Euthaha agnis tinna: D'Abrera, 1985 Euthaha agnijbnuis: D'Abrera, 1985 D'Abrera (1985) treated paupera and tinna as subspecies of agnis, He reported agnij?)nnis C`I as an independent species, but later threw doubt in its status: am almost certain that tinna is synonymous with ejther EL agnts or most unlikely, with El mena." 8. 0tsuka (1988) Euthaha agnts modesta: Ostuka, 1988 Otsuka (1988) said Euthalla agnis modesta was distributed in Borneo. But niociesta is from North Sumatra and his spocimen(s) should be called tinna, for there is no description of treating tlnna as a synonym of modesta in the report. Male and fernale are figured (tinna- type).
