Sexual behavior of the horned beetle, Allomyrina dichotoma septentrion-alis in plastic boxes was observed under three conditions : male-female, male-male, and female-female interactions. The courtship behavior showed the same pattern and consisted of the following five phases under any condition : approaching, abdomen shaking, mounting, licking, and abdomen bending. The male-male and the female-female courtship behavior were "homosexual" behavior. There were significant differences in the one-cycle time of abdomen shaking among the observed individuals. None of the males courted by the "homosexual" ones used their horns as weapons. The horns may be useless in preventing the courtship of "homosexual" males. Both males and females often fought against individuals of the same sex. However, none of the individuals courted by the "homosexual" ones attacked these "homosexual" ones. In A. d. septentrionalis, the "homosexual" behavior may inhibit the fighting behavior of individuals of the same sex.

Some experiments and field observations were conducted in 1970 and 1971 in Ino, Kochi, to assess the effect of micryphantid spiders, mainly Oedothorax insecticeps, upon the larval colony of the tobacco cutworm, Spodoptera litura. In the taro field, the density of the micryphantid spider was high in the rainy season, i.e. June to early July, but it decreased rapidly in early July. The low density was maintained during the summer season, although the spider was very abundant in wet places overgrown with weeds. On the basis of the functional response of the spider, it was estimated that the maximum number of hatchlings which can be eaten by a spider was 96 individuals during the 1st instar. Survivorship curves of the spider-free larval colonies in cages of nylon gauze were compared with those of colonies exposed to the spider in the cages. Sixty and 18 per cent of mortality were observed by the next day of hatch in exposed and spider-free cages, respectively. Of 60 per cent mortality, only 4 per cent was accounted for by the actual predation which was assessed by the number of head capsules left on the taro leaf. Since 18 per cent of hatchlings were dead in spider-free cage, remainder, i.e. 60-18-4=38 per cent, was loss by larval dispersal out of the leaf induced by the spider's attack. Egg masses composed of various numbers (100-900) of eggs were placed on taro plants, and changes in number were followed during the 1st instar. In the period from late June to early July when micryphantid spiders were abundant, the survival rates of 1st instar larvae were 2-3% regardless of the number involved in the colony up to 900 individuals per colony. Taking consideration of the maximum number of prey could be eaten by a spider, i.e. 96 individuals, almost all of the hatchlings would be killed indirectly by the disturbing effect of spiders.

The genus Rocalia TAKEUCHI is transferred from the subfamily Heterarthrinae to the Selandriinae because of such unique biological characters as the piercing-type of oviposition and the host-plant association with ferns. A new tribe Rocaliini is erected for this single genus based on derivative morphological characters, viz. the large posttergite, the deeply incised propodeum, the absence of prepectus and the tridentate mandible, on the peculiar larval feeding habit restricted to the spores of ferns, and on the specialized karyotypes consisting of many telocentric chromosomes. A second species, R. japonica n. sp., is described from Japan.

This paper presents the life histories and biologies of the two bagworms, Eumeta japonica HEYLAERTS and E. minuscula BUTLER, and comparative investigations of their parasite complexes. Thirty-five species of primary parasites and hyperparasites were reared from the two bagworms, 16 of which had not previously been reared from either host. Levels of parasitization of pupae are much higher than for larvae, but pupal parasites showed a strong preference for male Eumeta pupae, and this, coupled with the high fecundity of Eumeta females, limits the impact of pupal parasites on Eumeta populations. The differences found in the species composition and the rates of parasitization of the parasite complexes of E. japonica and E. minuscula are related to phenological, morphological, physiological, and/or chemical differences between the hosts and between the parasites.

Six braconid species are dealt with as parasitoids of the gall-making Cecidomyiidae in Japan. All of them, Bracon asphondyliae (WATANABE), comb. nov. (=Ipobracon scurra FISCHER, syn. nov.), B. sunosei sp. nov., B. tamabae sp. nov. (=Ipobracon scurra auct. partim), Simplicibracon curticaudis sp. nov., Testudobracon longicaudis sp. nov., and T. pleuralis (ASHMEAD), comb. nov., belong to the tribe Braconini of the subfamily Braconinae. They are all described and keyed. B. tamabae and B. curticaudis parasitize the leaf gall midges on broad-leaved evergreen trees, while the others parasitize the fruit, pod or flower gall midges on various Dicotyledoneae.

Habits and life histories of 5 Japanese species (see p. 1) of Chlaenius observed in confinement are summarized as follows : (1) Adult beetles feed on various kinds of living small insects or fresh meat, and under full supply of such food reject vegetable substance. (2) The female beetle deposits its eggs in mud cells, which are generally oblong, rounded and rough in surface, and occur on pebbles, grass leaves (Pl. 1, f. 3) or stems (Pl. 1, f. 1), dead grass stems (Pl. 1, f. 6), slim pieces of wood or bamboo (Pl. 1, f. 2, 7&8), or on the wall of a china pot in which the beetles are confined. Each cell contains one egg and is placed singly, but in a limited place it happens that many are crowded in a cluster (Pl. 1, f. 1). (3) The mud cell of C. pallipes is most dexterously constructed ; it is somewhat quadrate and has a side opening which is closed with a thin lid in a complete cell. The lid is represented, before the deposition of the egg, by a flap projecting from the upper edge of the opening (Pl. 1, f. 4). The hatching larva makes its emergence by breaking open the lid. The inner form of the cell is ellipsoidal and smoothfaced ; the 8th and 9th abdominal segments of the female seem to take part in its construction. The female does not oviposit within the year of its emergence, but does, after hibernation, from May to July. (4) Mud cells of C. circumdatus xanthopleurus and C. pericallus are similar to those of C. pallipes, but inferior to in elaborateness. Cells of C. inops and C. sericimicans are very roughly made. (5) Eggs are generally white, oblong and smooth. They are characterized in their striking softness, so that it could be thought that the protection of the mud cell had vital importance for them. Egg periods are shown in table 1. (6) The larvae of all the 5 species moult thrice and, with the exception of the case of C. circumdatus xanthopleurus, more or less change their coloration with stages. (7) Food of larvae is restricted to small living insects or fresh meat. (8) The full-grown 3rd stage larvae enter the soil, making a round cell for pupation. Duration of larval and prepupal stages is given in table 2. (9) Pupa is generally white and smooth, emits a bad smell. Duration of pupal stage is given in table 3. (10) C. pallipes takes about a month from oviposition to emergence of adult. (Tab. 4).

A new tribe of the family Tachinidae is proposed for a new genus comprising 3 new species from Japan, Taiwan and Vietnam : Leptothelairini tribus nov. (type-genus : Leptothelaira gen. nov.) ; L. longicaudata sp. nov. (type-species), L. meridionalis sp. nov. and L. orientalis sp. nov. This tribe seems to be close to Thelairini. Anechuromyia nigrescence, a new genus and species of the tribe Blondeliini, parasitic on an earwig Anechura harmandii in Japan, is described. Gibsonomyia CURRAN is synonymized with Phyllomya ROBINEAU-DESVOIDY. A synonymic note on Phyllomya aristalis (MESNIL et SHIMA) is given.
