There has been controversial issue on the classification of Chitoria sordida (Moore, 1866) and C. naga (Tytler, 1914). These species are similar to each other at a glance, but easily distinguishable. The diagnosis of each species is described. Chitoria sordida, ranging from Sikhim-Bhutan-Manipur to N. Myanmar (ssp. sordida) and from N. Vietnam to E. Laos (ssp. vietnamica) prefers lower altitude, ca 500m, whereas Chitoria naga, ranging from Nagaland-N. Myanmar-S. Yunnan-N. Thailand to N. Laos prefers higher altitude, ca 1,000-2,000m. The recently described C. sordida hani Yoshino, 1999 is sunk to a junior synonym of C. naga (Tytler, 1914). In addition, Chitoria modesta (Oberthur, 1906), often regarded as a subspecies of C. sordida, is separated from these two species.

Japanese species of the genus Geogepa are reviewed. A new species Geogepa monticola is described based on specimens collected in subalpine forests of central Honshu, Japan. The species is very closely related to G. stenochorda (Diakonoff, 1948).

Four species of plume moths (Pterophoridae) are dealt with. Three of them, Hellinsia tephradactyla (Hubner, 1813), Hellinsia didactylites (Strom, 1783) and Oxyptilus chrysodactyla ([Denis & Schiffermuller], 1775), were recently recorded from Japan, Hokkaido (Arenberger, 2002; Ijima & Kawahara, 2003), and adults and genitalia are illustrated. Albino specimens of Cnaemidophorus rhododactyla ([Denis & Schiffermuller], 1775) are recorded from Hokkaido and adult and genitalia are also illustrated.

Larvae of Sabahan Papilio memnon L. and P. polytes L. were reared under a photoperiod of 12L-12D or 14L-10D at 20℃. In both species, photoperiods affected pupal development, although there was no significant difference in the mean larval stages between photoperiodic conditions. In P. memnon, the pupal stage under the short day (23-27 days) was slightly but significantly longer than that under the long day (23-24 days). In P. polytes, four of nine individuals prolonged their pupal stages under the short day (29-92 days), while all individuals developed without arrest in development under the long day (19-21 days). The results show that these Papilio butterflies inhabiting the tropics near the equator have the ability to delay pupal development in response to a short photoperiod at the moderate temperature.

This study examined tortricids reared from two cecidomyiid fruit-galls collected in late autumn. 1) The fruit galls of a cecidomyiid on the herb Achyranthes japonica (Amaranthaceae) were sampled on 16 October and 20 November, and reared in the laboratory. The galls were fed on by the larvae of two tortricid species, Lobesia aelopa Meyrick and Adoxophyes dubia Yasuda and the attack rate was less than 5%. In addition, since the larvae of the gall midge had already matured on 16 October and most larvae had egressed from the galls by 20 November, the tortricids imposed little negative effect on the cecidomyiid larvae. 2) Adoxophyes dubia emerged from the fruit galls of a cecidomyiid, Asteralobia sp. on the liana Trachelospermum asiaticum (Apocynaceae). The larva of A. dubia bored into and fed on gall tissue and the gall was considerably damaged. However, most cecidomyiid larvae matured or had already exited the galls. In addition, the attack rate was 8.3% (N=12). These two tortricid species are facultative cecidophages that primarily utilize normal plant tissues rather than plant galls. The tortricid larvae may feed on gall tissues as an alternative food source due to a dearth of fresh leaves in late autumn.

The photoperiodic response was investigated in two newly established populations of Papilio memnon in Shizuoka and Kanagawa Prefectures, central Japan. Critical photoperiods for inducing pupal diapause were about 13hr and 13hr 15min in the Shizuoka (35°02'N) and Kanagawa (35°16'N) populations, respectively, and these were not different from those of temperate populations in western Japan. Results show that the distribution of this species has been expanding from western into central Japan without any remarkable changes in such a physiological trait as the critical photoperiod for inducing pupal diapause.

Leucania irrorata Moore, 1888 is considered to be a good species distinct from Mythimna griseofasciata (Moore, 1881). As the former becomes a junior secondary homonym of Mythimna irrorata (Moore, 1881) (=Axylia irrorata Moore, 1881), a new replacement name, Mythimna decipiens, is proposed for it. The male and female genitalia of these two species are illustrated and described.

Anchinia cristalis (Scopoli, 1763), a poorly known moth in Japan, is redescribed on the basis of specimens reared from larvae on leaves of Daphne jezoensis Maxim. (Thymelaeaceae) in Hokkaido, northern part of Japan. Information on its larval and pupal habit is given on the basis of observations on the Hokkaido population, throwing a doubt on previous reports. Proposals on the family-group placement of the genus Anchinia that were suggested in the past 30 years are reviewed and compared with each other. The proposal of Leraut (1997), placing Anchinia in the subfamily Hypercalliinae of the Oecophoridae sensu lato, is regarded as the most reasonable one at present.
