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.

3種の素材(ムシロとビニールムシロ, ダンボール)を使用したバンドトラップを異なる環境のマツに設置し, 捕獲された害虫と天敵, クモを調査して, 慣用されている"こも巻き"法を再検討した.1)全捕獲個体の63.2%が昆虫, 34.6%がクモであった.マツ害虫と天敵はほぼ同個体数が捕獲された.前者ではマツワラジカイガラムシ, マツノホソアブラムシ, マツオオアブラムシとマツカレハが優占種で, 後者の91%はヤニサシガメであった.クモは20科43属51種が確認され, フクログモ科, エビグモ科, ハエトリグモ科が優占的であった.2)設置環境別では, 害虫と天敵, クモはともに林地など植生が比較的豊富で, 下草ないし落葉などで地表がおおわれている環境では捕獲数が少なく, 公園や施設構内など植生が貧弱で地表が落葉などでおおわれていない環境では多く捕獲された.3)害虫はダンボールで圧倒的に多く捕獲された.天敵はムシロで多く捕獲されたものの, ビニールムシロとダンボールでもかなり捕獲され, 有意差はなかった.この傾向は両昆虫群の中の主要種でも同様であった.マツカレハ幼虫はアブラムシとカイガラムシほど素材間で顕著な差はなく, ダンボール, ビニールムシロ, ムシロの順で捕獲された.クモの捕獲数は素材間で有意差はなかった.4)バンドトラップ法の効率化には, 越冬に入る前の早期設置と翌春の脱出前の早期回収が必須であり, ついで, 対象昆虫群に対応した素材の選定が要請される.

The species-group of O. yasumatsui KISTNER of the genus Oligota MANNERHEIM is dealt with. It is composed of the two species, Oligota yasumatsui KISTNER and O. kashmirica CAMERON, whose adult and larval stages are predaceous on the red spider mites. A new subspecies, O. kashmirica benefica, is described. Illustrations of important characters of the species and the biological notes are also given.

Males of a Japanese paper wasp, Polistes jadwigae DALLA TORRE, defend mating territories. Males waited for females at cracks opened on walls or corners of eaves and some of these places were used by females as hibernacula. These males bent their abdomens upwards on warm and sunny days from middle October to middle November. Abdomen-bending males were dispersed evenly. Waiting males chased off other males which approached the cracks or corners of eaves and copulated with females which came to these places. In cases where change in ownership of territories resulted, physical contacts between males were always observed. The duration of territorial possession by a male was, as a rule, within a single day. The radii of territories ranged from 20 to 50cm.
