Cambridge has kindly sent me English specimens of L. amen- 

 tata, of both sexes, under the name of L. saccata Blackw. Of "L. 

 palndicola C. Koch", I have received of L. Koch specimens from Ba- 

 varia. The species is met with far up in Lappland and the Nor- 

 wegian Finnmark. 



The cephalothorax varies in length between 4 and 3'/ 2 millim.: 

 it is always perceptibly shorter than the tibia + patella of the 4 th 

 pair, which together are 5 — 3 3 / 4 millim. long. By this both sexes 

 are immediately distinguished from L. paludicola, and the female is 

 additionally so by it always distinctly and strongly annulated legs. 

 The organs of copulation are also quite peculiar. The vulva consists 

 of a little depressed area rounded in front and truncated behind, 

 bounded by parallel sides, and little longer than it is broad; in 

 front it exhibits two tubercles or ridges, directed obliquely backwards 

 and outwards, and it is moreover crossed by a longitudinal septum, 

 narrow in front but rapidly and strongly dilated at the posterior 



i extremity : by these tubercles and the septum the area is divided into 

 four small fovea situated almost in square. In the male the tibial 

 joint of the palpi is dilated towards the extremity, and scarcely 

 half as long long again as it is broad at the base, thickly clothed 



! with deep-black hair, which is longer and more outstanding towards 

 the apex of the joint, so that it there looks broader than it is, al- 



i most as broad as the lamina; this latter is short, and black (even 

 at the apex on the under side, in front of the bulbus); the bulbus 

 is also black, and very small. Sometimes however the lamina and 

 bulbus are of a somewhat paler colour. In front of the tumid 

 basis of the bulbus, on the under side, projects a black or dark 

 brown spine, pointing almost forwards, curved outwards and tape- 

 ringe quably to a fine point; this spine, when viewed from the side, 

 is not curved upwards, but straight, and its extremity even rather 

 curved a little downwards. 



In L. hortensis n. or L. saccata C. Koch, which is considerably 

 smaller than L. amentata (the cephalothorax 2'/ 2 — 3 millim., tibia 

 + patella of the 4 th pair 2 3 / 4 — 3 f / 2 millim.), the vulva occupies an 

 oblong area, and consists first of a large, rounded fovea open be- 

 hind and bounded by a fine semi-elliptically curved costa; in this fo- 

 vea, near the ends of the costa, is a small oblong tubercle on either 

 side; the fovea is divided by a longitudinal fine septum, which is 

 continued backwards to the rima genitalis, where it is almost tri- 

 angularly dilated; on each side of this septum, near its posterior
