Japanese species of the genus Peromitra Enderlein are revised. Five species are recognized and four of them are described as new to science : P. fimbriata sp. nov., P. purpurea sp. nov., P. pilosa sp. nov. and P. hikosana sp. nov. A known Japanese species are redescribed and discussed. A key to Japanese species is provided.

To elucidate the diapause pattern of Lepisma saccharina Linnaeus, strains collected in Hirosaki were kept under controlled conditions of photoperiod and temperature. The interval between moults was uniformly short in the first two instars, but tended to increase in the later instars and showed a very large variation owing to the occurrence of diapause in some individuals but not in others. When reared at 25℃, this insect started oviposition in the 9th or 10th instar but thereafter continued to grow and moult. Some individuals survived 2.5 years or more and moulted more than 30 times. The incidence of diapause as defined by the instar duration of longer than 50 days was affected by temperature, photoperiod and age. The duration of diapause was highly variable among individuals, lasting more than 180 days at 25℃ in extreme cases. Diapause may occur in any larval and adult instar but not in the first two instars, and may be repeated in separate or consecutive instars. Some individuals underwent 8-9 diapause instars in 600-800 days. At 20℃, diapause occurred in the younger (3rd and 4th) instars at a higher frequency, and a photoperiodic response of the long-day type was manifested more clearly, than at 25℃. A high temperature of 28℃ prevented diapause at least in the larval stage under both short (12h) and long (16h) photoperiods.

Field observations showed that the gall-parasitic flea weevil Rhynchaenus hustachei often parasitized the pouch galls of the aphid Paracolopha morrisoni on Zelkova serrata leaves in the Kinki District, Central Japan. The eggs of the weevil were laid into the gall walls and hatched larvae entered the galls. Each parasitized gall contained only one weevil. The inside of the gall wall was heavily grazed by the weevil larva, resulting in destruction of the aphid colony. These observations suggest that the weevil is an obligatory cecidophage. At three of six study sites, weevil parasitism was the greatest mortality factor for the aphids. A facultative hyperparasitoid, Eupelmus urozonus (Eupelmidae) and Pteromalus sp. (Pteromalidae) parasitized the larvae and pupae of the weevil.

Mepleres suzukii (Okamoto, 1910) (Psocoptera: Pseudocaeciliidae) was redescribed. Mepleres Enderlein, 1926 had been incorrectly treated by some authors as an invalid synonym of Pseudoscottiella Badonnel, 1946. Thus, Pseudoscottiella was appropriately treated here as a junior synonym of Mepleres. Meniscopsocus Li, 1993 was newly synonymized with Mepleres. All new species combinations resulting from these taxonomic treatments were listed. Within Mepleres, African and Oriental-Pacific-Australian species groups had been recognized, with Mep. suzukii assigned to the latter group. However, monophyly of the latter group could not be justified, whereas the African group was regarded as monophyletic. A key to Japanese Mepleres was provided.
