hardly rises over the surface of the bulbus. The vulva in T. inqui- 

 lina is composed of two long, thin, parallel, elevated lines, separated 

 only by a fine furrow, and which at the rima genitalis bend out- 

 wards almost at a right angle, thus forming together a narrow 

 anchor or ^. 



Of the synonyms given by Walckenaer to his L. fabrilis, L. sa- 

 bnlosa Hahn does not belong to it, but to T. andrenivora or barbipes. 

 He erroneously takes up L. melanogaster Hahn under both his L. 

 (Tar.) narbonensis and his L. captans (H. N. d. Ins. Apt., I, p. 

 283, 306). L. narbonensis Walck., or T. melanogaster (Latr.), which 

 Westring supposes to stand in close relationship with T. fabrilis., is 

 an incomparably larger spider: the cephalothorax of a specimen in 

 my collection is near 14 millim. long, whereas in T. fabrilis it rarely 

 exceeds 7 millim. L. captans Walck. , on which see the next fol- 

 lowing species , more nearly resembles T. fabrilis (Clerck).
