A lectotype is designated for L. striata LEECH, a pest of sorghum and maize, and one new species, L. substriata, is described. Descriptions of male and female genitalia are given to another related species, L. insecuta WALKER.

Matsumuraeses capax RAZOWSKI et YASUDA which was taken in the subalpine gravel zone (alt. 2400 m) of Mt. Fuji is new to the Japanese tortricid-fauna. The mature larva of this species was found in the pod of Astragalus membranaceus BUNGE in the early of September and emerged in October but a part of them hibernated in the pupal stage.

In this paper, the subspecific characteristics of the eggs, larvae and adults of lunar moths, Actias gnoma (BUTLER) and A. artemis(BREMER et GREY), are described. Results of inter-subspecific crossing of the moths and discussion on the zoogeography of the two species are also given. 1. In adults, A. gnoma mandschurica from Hokkaido and A. gnoma gnoma from Honshu are similar but A. gnoma miyatai from the Izu islands is definitely different from them. The latter has smaller body and fore-wing with small eye-spot and soft curved apex than the former two. The adults of two subspecies of A. artemis, A. a. artemis from Hokkaido and A. a. aliena from Honshu, show no detectable differences in the morphological characters. The male of subsp. artemis has blue wings instead of yellow ones found in A. a. aliena. While, the non-diapausing pupae of A. a. artemis, reared at high temperature (25℃) and long-day conditions, yield yellowish males which are similar to the summer form of subsp. aliena. 2. There are obvious differences in the coloration among the 1st inster larvae of Actias subspecies. The head, prothoracic shield, setae and body surface are black in A. gnoma mandschurica and A. artemis artemis from Hokkaido blackish-brown in A. gnoma gnoma, yellowish-brown in A. artemis aliena from Honshu and pale reddish-yellow (Hachijo-jima) or reddish-brown (Kozu-shima and Miyake-jima) in A. gnoma miyatai from the Izu Islands. The variation of the larval coloration can be regard as adaptation to temperature in their habitats. 3. The male genitalic structure of A. g. miyatai is different from the other subspecies. In the former, the uncus has dorsal lamellar plates which are laid to overlap each other and incurved, while in the latter two, uncus has broad lamellar ones which are recurved. The length of the juxta in subsp. miyatai is shorter than in subsp. gnoma and the processes from juxta in the former are nearly symmetrical but those of the latter are asymmetrical, that is, the right process is longer than the left. The symmetrical juxta of the former may be considered more primitive than the latter, because asymmetrical ones are found related species, A. selene and A. neidhoeferi. 4. Hybrids of crossing among these subspecies showed the intermediate characters of their parents in the first (F_1) and the second (F_2) generations. 5. The difference of geographical distribution of the two species may have been due not only to differences of their food plants but also to difference of their invasion periods into Japanese Islands in Old ages (perhaps in cold climate Pleistocene). A. artemis is general feeder of broad-leaved deciduous trees. On the other hand, A. gnoma is oligophagous on alders (Alnus species). As was pointed out by PEIGLER (1986), A. gnoma would have changed it's food plant into alders in the glacial period. Perhaps, a factor preventing immigration of A. gnoma to Kyushu might have been effuse distribution of the food plant. 6. The allopatric distribution of two ssp. of A. gnoma, A. g. miyatai from Kozu-shima to Aoga-shima Islands and A. g. gnoma from Honshu to Izu-o-shima Islands, is particularly interesting. This phenomenon seems to be the result of difference of historical ages of the invasions of the two subspecies. It seems that A. g. miyatai did not specialize in the Izu Islands but arose in somewhere in the Continent Asia. After the settlement of miyatai, the Izu Islands were isolated and the new dominant subspecies, gnoma, could invaded only Izu-o-shima which is volcanic and the closest to Honshu.

In this paper I describe two new species of Telorta WARREN, 1910, from Taiwan. Both species are closely related to T. divergens (BUTLER, 1878), the type-species of the genus, from Japan, E. Siberia, Primorye, Korea and the continental China.

Euplexidia HAMPSON, 1896, is a genus established for a sole species, Euplexidia noctuiformis HAMPSON, 1896, of Assam, and has not so far been revised taxonomically. In this paper, I enlarge the category of this genus to include Himalayan Dianthoecia literata MOORE, 1882, now associated with Euplexia STEPHENS or Trachea OCHSEN-HEIMER, and at this time, I describe four new species similar to or in part formerly confused with literata, and one new subspecies of literata from Thailand.

Nigilga WALKER is a small group, including five known species only, i.e., adjectella WALKER, limata DIAKONOFF and ARITA, seyrigella VIETTE, talhouki DIAKONOFF and toulgoetella VIETTE, from the Ethiopian, Oriental and Palaearctic Regions. In the present paper, a new species of the genus is described from a male specimen captured in the island of Sulawesi. This is the first record of the genus from the Australian Region. I wish to thank Dr. S. MORIUTI of University of Osaka Prefecture for reading the drafts of this paper.

The genus Herculia belongs to the Pyralinae and is represented by four species in Japan. However, no information on the immature stages of the genus has been available so far. Fortunately I got the larvae and pupae of Herculia pelasgalis which will be described in the following lines. Those specimens were reared from eggs laid by a captured female and were treated in 10% KOH solution and preserved in 70% ethanol for the examination.
