Chaeopsestis ludovicae LE CERF, 1941, is a very rare thyatirid moth described from North Vietnam, Tonkin, Chapa, as a new genus and a new species, and there has been appeared no subsequent record in literature since its original description. When I cited this genus in my previous paper on the genus Neotogaria MATSUMURA, 1933 (YOSHIMOTO, 1984), it was merely based upon the examination of the photographs of moth and male genitalia of the type specimens preserved in Museum National d'Histoire Naturelle, Paris. Through the courtesies of Dr. S. MORIUTI, University of Osaka Prefecture, and Mr. S. SUGI, Tokyo, I could have a good opportunity to examine a rich material of this rare moth brought from North Thailand by the Japanese Expedition to Thailand 1985, organized by University of Osaka Prefecture. In this short note, I first record this species from North Thailand and describe the male and female genitalic structure.

The genus Hydatocapnia WARREN, 1895, of the subfamily Ennominae, has been represented by the following three species and one subspecies: H. marginata (WARREN, 1893), the type species of the genus, from N. India and Taiwan, H. marginata demensa PROUT, 1935 from Java, H. fumosa WARREN, 1897 and H. subapicata WARREN, 1904, both from Niger. In the present paper, I will describe two new species of this genus from Sulawesi and the Philippines, respectively. In writing this paper, I must express my cordial thanks to Dr. M. OWADA, the National Science Museum (Nat. Hist.), Tokyo, for his kind permission to use invaluable specimens from the Philippines, and also to Mr. Y. KISHIDA, Tokyo, for his kindness in offering me valuable specimens from Sulawesi. My sincere appreciation is also due to Dr. H. INOUE, Otsuma Women's University, Iruma, for his constant advice in the cource of my study.

Final (5th) instar larva of Mycalesis francisca formosana FRUHSTORFER from Taiwan (Formosa) is distinguished morphologically from that of M. francisca perdiccas HEWITSON from Japan in following points : 1) a pair of head projection longer ; 2) abdominal colouration not dark brown but ochre-yellow or light brown ; 3) dorsal line darkened in the 6th-10th abdorminal segments.

Morphological characters of Neope niphonica kiyosumiensis TAKAHASHI et AOYAMA(Lepidoptera: Satyridae) from Boso Peninsula, Chiba-ken (Prefecture), Central Japan, were compared with those of N. n. niphonica BUTLER from the prefectures of Shizuoka, Yamanashi and Kagoshima. Egg of the subspecies kiyosumiensis is smaller in diameter than that of the subspecies niphonica. Head width of the 1st inster larva of kiyosumiensis is also smaller than that of niphonica and a dark brown lateral band around the head is recognized in many individuals of the 1st instar larva. Along the dorsal line of the 2nd-4th instar larvae of kiyosumiensis, a row of prominent dark brown patches is found in many individuals. This characteristic is unknown in other subspecies of this butterfly. The pupa of kiyosumiensis is smaller and lighter than that of niphonica and has less dark patches.

In order to study the interspecific relationship between Parnassius glacialis and P.hoenei, the authors carried out hybridizing experiments between P. glacialis ♀ and P. hoenei ♂ by hand-pairing and field surveys in search of natural hybrids in some localities where these species concur together. The F_1 hybrids obtained experimentally developed normally into the adult stage, producing large specimens of both sexes. The morphology of the larva, pupa or adult of F_1, including that of the external genitalia, revealed precisely intermediate features. Wild specimens comparable to the F1 adults collected in some localities in Western Hokkaido accounted for 6 to 22 percent of the total population. These adults are considered to be interspecific hybrids because of their similarity to the experimentally raised F_1 hybrids. A wild last instar larva collected in one of these habitats, and its pupal and adult stage were similar to those of the experimentally obtained F_l. As a result, it is presumed that natural interspecific matings occuring frequently in these localities.

A total of 163 adult males of P. bianor complex were collected in 1986 at three localities on the mainland of Japan, on the main island of Okinawa, and on Ishigaki Island. The butterflies collected from these localities are classified taxonomically into separate subspecies and make up a P. bianor complex. Fluid extract of the individual male was analyzed with gel-electrophoresis at six isozyme loci. The gene flow and genetic distances between these populations were examined using the resultant allelic frequencies. Specific alleles were fixed independently, both in the alcohol dehydrogenase locus and in the acid phosphatase locus between the three populations. There was no indication of geneflow between the populations. The remaining four isozyme loci depicted similar patterns of divergence, but with less prominence. Genetic distances, calculated by the formula of NEI (1972), were 0.896 between populations on the mainland of Japan and on the main island of Okinawa, 0.737 between populations on the mainland of Japan and on Ishigaki Island, and 1.268 between populations on the main island of Okinawa and on Ishigaki Island, respectively. The magnitudes of these distances strongly suggest that the divergence observed in the island populations of P. bianor complex is significantly greater than that of interpopulationals within a single species. Allopatric speciation is in progress with the aid of random fixation of genes due to the limited number of individuals in island populations of P. bianor complex.
