In Japan, the generic name Scolioplanes has been applied to a group of Geophilidae ever since, but the author holds the same view with CRABILL JR. and other European authors who have been using Strigamia instead of Scolioplanes for the genus. Two new species S. platydentata spec. nov. and S. bicolor spec. nov. are described here.

While there are a few reports on myriapod fauna of Tôhoku District (the Northern Part of Honshû), there seems to be no report on myriapods of Towada District. Towada District here, is meant by the area around the big lake, Towada which measures 48km. round, spreading over Aomori and Akita Prefectures. The junior author, Shinohara, had a chance to visit the Lake and, although he could collect only five species of Diplopods and four species of Chilopods, he was lucky in founding among them two new species. Descriptions on them is stated herebelow. What is learnt as a result of consideration on generic diagnoses of Genus Kopidoiulus and Genus Ikahoiulus is also stated. We also added remarks on myriapods found in Irimizu Limestone Cave, Fukushima Prefecture.Epanerchodus towadaensis Shinohara sp. nov.Body length about 18-28mm, width of postcephalic somites 2.5-3.5mm. General color of dorsum darkish brown but legs and somites are yellowish brown. Collum semicircular.Carinae are more or less narrow and produced at caudal end in a short after about the sixth postcephalic plate, and more strongly produced in posterior segments.Tibiotarsus of gonopods of male clubbed with distal portion of it divide in two blades. Distal end of main blade is a little inflated and short bifurcated, but shorter blade rolled outside. Femuroprocess large, and horn long and slender.Holotype: a male (body length 25mm) obtained at Towada, Aomori Prefecture on Oct. 9, 1955. Allotype: a female (body length 28mm). Data same as above. Type specimens were collected by Shinohara and are preserved in his collection.Fusiulus komatsui Shinohara sp. nov.Body length about 17mm. Body width about 1.0mm. General colour brownish black and legs are yellow with darkish brown spots. Number of segments 48 in male. Repugnatorial pores light yellow, fixed the position behind the suture of segments.Setae of the first pair of legs are (1)+(3-4)+(3+5). Inner base and distal end of the second joint of the first pair of legs are areolate, and process of the knee is projected slightly. Penis bifurcate and projects over the anterior margin of coxae of the second pair of legs.Pregonopod of male resembles to that of F. quadratus, but inner angle of distal margin more or less like a protuberance. Postgonopod with thin blades on distal end, and outside of it with two uncertain processes but without cilia on the whole surface of gonopods.Holotype: a male obtained at Towada on Oct. 9, 1955 by Shinohara. The type is preserved in Shinohara's collection.

The train millipedes, Parafontaria laminata group, are endemic in Central Japan and notorious for stopping trains during their outbreaks. Recently, it was established that the train millipede contains 3 species and 1 subspecies (P. laminata laminata ATTEMS, P. laminata armigera VERHOEFF, P. kuhlgatzi VERHOEFF and P. echizenensis SHINOHARA). The distribution of each species is restricted to a certain locality. P. laminata armigera is distributed in the mountainous region of Central Japan. Outbreaks occurred in autumn, at 8 year intervals, or in both 7th and 8th years in this region. The outbreak population consisted mainly of adults, but also 7th instars at times. The adult P. l. armigera laid eggs early in the next summer and died. The eggs hatched in the summer and the 1st instar larvae hibernated in the winter without molting. The larvae lived in the soil, molted once a year, and became adults after the 7th molt. The adults and some 7th instars swarmed on the soil surface in autumn, which was regarded as the outbreak. The swarming records of the other train millipedes were arranged according to the locality, although the periodicity of the outbreak is not clear.

Nedyopus venustus sp. nov. Body Iength about 18mm, width about 1.3mm in the male. General colour is brown with a wide light longitudinal stripe extending on the middorsal surface the collum to the tail excluding the head. The keels, sternites and legs are yellow but tibia and tarsus of legs have a brown tinge. The dorsal surface is glabrous, and many conspicuous furrows are present on lateral and upper surfaces of the keel. The lateral carinae extend from the first to the sixth dorsal segment, the seventh and posterior segments having none. The fifth sternite of the male possesses a hairly flat lamina, the anterior margin of which curved in slightly. Gonopod of male : Hairly prefemur has a small process on the inner surface of its distal end. the base of femur is not retrograde as is that of N. tambanus, but expands markedly in a proximal direction as shown in the figure. The seminal groove branch runs forward or downward. Ratio of length to width of the male gonopod excluding the prefemur is about 2 : 1. Holotype : One male, Mt. Kirishima of Pref. Kagoshima, April 22, 1956 collected by Mr. S. Koshiyama, and preserved in the auther's collection. Kopidoiulus longus sp. nov. Body length is about 38mm in the male. The general colour is darkish brown, but metazonite possessas brown spots, and the dorsum seems to have many lateral stripes on account of the light stripes on the posterior of each segment. The sternites and the legs are yellow. The anal segment is deep brown. The number of segments is 49. The crypeus is hairly, but setigerous foveolae possess 2 + 2. Ocelli number about thirty. Few transverse furrows are present on the prezonites, and the striate portions of metazonites exist below the level of the repugnatorial pores, the dorsal surface being smooth. The first legs are transformed into long, stiff and stick-like five articles curved deeply as a whole. At the distal end of the fifth article is situated a very small process which is probably a degenerate claw. Gonopod : The anterior gonopod consists of a telopodite and a coxal process. Telopodite is spindle shaped having a seta on the inner surface of the distal end. The coxal process is long, with a small blade situated on one side of the distal half, and a few short seta-like processes on the basal half. Posterior gonopod is a long, slightly bent slender blade, with a ciliated end. The gonopods of the male are represented in the figure. Holotype : One male, Mt. Daisetsu, Hokkaido, July 24, 1957, collected by Dr. H. Kobayashi, and preserved in the auther's collection.

The Japanese pill milliped, Hyleoglomeris stuxbergi, showed photo-orthokinetic, thermoorthokinetic and photo-klinokinetic responses under various light and temperature conditions. Although this species is nocturnal (Fig. 5-9), over-all activity was stimulated by light (10-2000lux) (Fig. 1-3) and higher temperature (5-41℃) (Fig. 4). But this contradiction is easily explained when the 15 patterns of responses of this species were classified in two categories of positive (favorable) and negative (fugitive) ones (Table 1). The enhancement of activity under a brighter condition was largely due to a decrease of positive response as virtual inactivity. Negative responses as vigilance and defensive responses also increased under the light (Table 2 and Fig. 8). This milliped is nocturnal because it shows negative response in the daytime and positive response in the night.
