After examining the figures given by Walckenaer in the Faune 

 Franc, of his Lyc. andrenivora, I am perfectly satisfied that Black- 

 wall has done right in assigning the specific name of andrenivora 

 Walck. to the spider before us. In that of Walckenaer's figures, 

 which represents the male, the tibiae of the first pair are not, it is 

 true, thickened, as they are in L. andrenivora Blackw. and L. barbipes 

 Westr., but they are not so either in specimens of L. inquilina C. 

 Koch from Bavaria, which I have received from Dr L. Koch, and 

 which in every other respect agree with the Swedish specimens of 

 L. barbipes Westr. and L. andrenivora Blackw., of which last Cam- 

 bridge has been kind enough to send me $ and 2 ad. from England. 

 Dr Zimmermann has also favoured me with a $ and $ ad. of his T. 

 barbipes, which accurately agrees with the form occurring in Sweden. 

 Between the females of the spiders, which Blackwall, Westring and 

 C. Koch describe under the above names, I can discover no differ- 

 ence whatever. It therefore appears to me certain, that the form and 

 hairy covering of the male s fore-tibia vary in this species: in the nor- 

 thern specimens, as also in those from England and Silesia, these 

 tibiae are considerably thicker than those of the succeeding pairs, 

 (but cylindrical, not egg-formed, as in T. cuneata cf) and thickly 

 covered icith black hair, especially on the under side, whereas these 

 tibia? in south-German, and probably also in French and south-Eu- 

 ropean males generally, are little, if at all, thickened, and with the 

 liairy covering but little thicker than that of the succeeding pairs. In 

 the males of a few other species, f. inst. T. pulvendenta and T. 

 acrdeata, I have observed that the fore-tibia? are often a little thicker 

 in specimens from the most nothern localities of Scandinavia, than 

 in individuals from other parts of Europe. 



From Simon I have received a ? jun. from Paris under the 

 name of L. andrenivora Walck., which I cannot distinguish from 

 L. barbipes Westr. — Ohlert's desciption of "Tar. inquilina" appears 

 to be only an extract from C. Koch's. — The figure given by Hentz 

 of his Lycosa ocreata bears so strong a resemblance to our Swedish 

 "Lyc. barbipes", that I could not but include that American spider 

 among the synonyms of the latter.
