The tibial joint of the palpus in cf is not double as long as it 

 is broad, somewhat shorter than the patellar joint. The bulbus has at 

 its outer margin, near the apex, a tolerably long, almost straight 

 process or blunt spine, directed inwards and somewhat backwards. 

 The vulva is formed of two small, obliquely situated, oval fovea?, 

 separated by an interval or septum narrow in front and rapidly di- 

 lating backwards.

That De Geer by his Ar. ruricola, under which species he er- 

 roneously classed Ar. cuneatus Clerce , understood this spider, so com- 

 mon throughout all central Sweden, cannot with the least appear- 

 ance of reason be doubted, and although he, like many later wri- 

 ters, may have confounded the next following species, 2r. terricola 

 (2r. trabalis C. Koch) with it, that cannot supply any reason for rob- 

 bing Westring's L. ruricola of the specific name, which has priority 

 before all others, and by which it is known to most foreign and 

 all Swedish arachnologists. L. ruricola Latr. and L. agretyca Walck., 

 under which Ar. ruricola De Geer is cited, are probably collective 

 appellations for both species, and the same is the case with L. ru- 

 ricola Sund. The size assigned by Walckenaer in H. N. d. Ins. 

 Apt. to his L. agretyca (6 or 7 lines), seems to suit best with Tr. 

 ruricola: his statement (Faune Franc., Arachn., p. 19) that the last 

 joint of the palpi in $ is black, agrees only with Tr. ruricola; his
