Length: female, about 1mm; male about 0.5mm. General colour yellow, brownish yellow, greenish, rose, or violet. Eye-spots large, black. Ocelli 8+8. Antennae purplish violet, slightly longer than the head, with fourth segment not subsegmented. Antennae of male with second and third segments modified to form clasping organs. Abdomen segmented dorsally. Unguis of first and second feet slender, with inner margin unidentate a little beyond the middle; unguiculus extending about one-third as far as the unguis, acute, with a subapical filament as long, to twice as long, as the claw proper. Unguis of third feet one half to three-fourths as long as those of the other feet, somewhat broader feebly curving, without teeth; unguiculus about one half as long as the unguis, broadly lanceolate, with subapical filament exceeding the unguis. Third tibio-tarsi with a peculiar distal sense organ consisting of a pair of slipper-shaped structures, with a stout seta extending beyond the tibio-tarsus. Ventral tube with smooth wand. Furcula, long, almost reaching the mouth. Dentes three times as long as mucrons. Mucrons convergent, spoon-like in general form, elliptical from above, with stout pigmented midrib, and three colourless lamellae as follows: (1)inner dorsal, with radiating ribs terminating in marginal teeth; (2)outer dorsal, with faint radiating ribs due to dorsal ridges, but with entire margin; (3)ventral lamella, narrow and entire. Basal lateral mucronal seta present. Tenaculum with a large anterior lobe extending below the rami, and bearing a pair of long anterior setae and a pair of short apical setae. Integment tuberculate. The material I have studied has been transfered to me by Mr. S. KINOSHITA. Locality: Honjo, Tokyo (June 20, 1916 and Apr. 3, 1919; abundantly on the surface of the water of the pond and on the stone of the pond's edge) Collector: Mr. M. TAKESHITA Distribution: Europe, North America, Japan.
