voured by L. Koch and Obleut, is identical with Leimonia riparia 

 Ohl. (non C. Koch). It is however easily distinguished by the legs 

 being thickly and distinctly anuulated, especially in the male, and 

 by the cephalothorax of the female having the three pale longitu- 

 dinal bands covered with yellowish- or reddish-white hair, so that, 

 as far as regards colour , the female much resembles L. monticola 

 (Clerck). L. prativaga is sligthly larger (the cephalothorax about 

 3 millim.) than L. puUata. The vulva, in L. prativaga, consists of 

 an area broader than it is long, and broader in front than behind; 

 in the anterior part it exhibits two large, almost triangular fovea? 

 situated at a pretty good distance from each other, with their apices 

 directed outwards, and immediately behind them, and somewhat nearer 

 together, two oblong, short, bright elevations, forming a continua- 

 tion of the posterior angles of the above-mentioned fovese; between 

 these two elevations or costse is a third, which is almost triangular, 

 with the apex pointing forward and connected with the interval be- 

 tween the fovese. The male's bulbus genitalis shows no easily observ- 

 able difference from that of L. pullata; nevertheless the finer spine, 

 which in L. pullata shows itself in front of the usual, coarser one, 

 is in L. prativaga scarcely discernible, and for the most part con- 

 cealed by the coarser spine. See L. Koch, loc. cit., as also above, 

 p. 304. — L. prativaga, which had not hitherto been recognised as a 

 Swedish spider, I have myself met with at Soderkoping; it has also 

 been captured in Skane by Mr Eisen and Mr Koth. 



L. riparia C. Koch') is nearly allied to L. pullata and Z*. pra- 

 tivaga: it is about the same size (cephalothorax 3, patella + tibia of 

 the 4 th pair 3'/ 2 millim.), and the colour is also nearly the same, 

 only somewhat paler. The legs are marked with very distinct dark 

 rings, at least in the female, the coxae of which are yellow. (In 

 the only male specimen I have seen, only the thighs are distinctly 

 annulated). The male's palpi are almost totally black; the bulbus 

 is scarcely swelled on the under side at the base; the ordinary spine 

 is brownish, quite uncommonly long, issuing near the inner margin 

 of the bulbus; it is directed forwards and outwards, and reaches 

 beyond the outer side of the apex (or solid, not excavated part) of

 scribed a North American species under the name of Lyc. riparia as early as 

 1844 (Descr. and fig. of the Aran, of the U. States, in Boston Journ. of Nat. 

 Hist., p. 389, PI. XVII, figg. 13—15). This species appears however not to be- 

 long to Lycosa sensu strict., but to Pirata.
