The material contains a few g jun. of equal size with + with ova. They differ in no respects from the V with the exception that ant. 2 (ant. 1 is broken) has a great number of very short joints, but the total length of ant. 2 is not greater than in 9- The species belongs to the group with short, narrow, not projecting epistomal plate; it may be deter- mined by the Key (see above p. 66) § 4 seq. *6o. Orchomene laevipes 11. sp. (Fig. 12 partim). Occurrence. This new species was once secured by the "Ingolf". W. of Iceland: St. 95. 65°i4'N., 30°39'W. 1318 m., temp. °. 2 V abt. 7—9 mm. $ 9 mm. (without marsupial plates). Body rather slender. Head shorter than the first mesosome segment ; lateral corners narrow and highly projecting. Eyes colourless and very indistinct. Ant. 1: 1. joint in the peduncle cylindrical, flagellum 8(9?)-articulate, accessory flagellum abt. s/3 the length of the flagellum, (>-arti- culate. Ant. 2 only a trifle longer than ant. 1, flagellum 8-articulate. Epistomal plate very little projecting. P. 1—p. 4 almost totally as in P. 5—p. 7 with almost even hind edge of 2. joint (there are only a few, 5—7, extremely small rounded teeth); for this reason I propose the specific name: Icrvipcs). The hinder process on 4. joint is long an
