 Blackw. — From the synonyms given under this species, those taken 

 up under "Var. should be effaced, as this "Var. /?" appears to be 

 a separate species: see next article. See also preceeding page.

I have these last years received several English and German 

 specimens of M. albimacula Westr., preserved in spirit of wine, and 

 have thus been able with greater precision to study its sexual or- 

 gans, which appear to show, at least in the male, such differences 

 from those of M. segmentata, that it cannot well be doubted that it 

 is a good species. As however Westring only by a mistake gave 

 this species the name albimacula, taking it to be identical with- 

 Zilla albimacula C. Koch {E, cliodia Walck.), there is certainly no 

 reason to retain that name, and I therefore call this spider Meta 

 Mengei (Blackw.). — In both M. segmentata and M. Mengei the 

 bulbus genitalis of the male, on the outer side, near the apex, exhibits 

 a horny, generally brown band or half-ring, which curves from the 

 upper (outer) margin of the lamina to the apex of the under side of 

 the bulbus; this band becomes broader towards the apex in M. seg- 

 mentata, but in M. Mengei it becomes narrower towards the apex. 

 The hairless process of the tibial joint is in both species provided 

 with a tooth, which in M. segmentata is situated at the base, in M. 

 Mengei near the middle of the process. The females are more diffi- 

 cult to distinguish. In M. segmentata the vulva consists of a little 

 transversal area close to the rima genitalis, which by two small de- 

 pressions or notches in the posterior margin is divided into three 

 parts, of which the two exterior are small and formed each of a 

 low dark tubercle, the middle part is larger, transversal, limited be- 

 hind and at the sides by an elevated , in general yellowish edge and 

 slightly excavated on both sides above. In M. Mengei the vulva 

 has the same appearance, excepting that it is longer, and its po- 

 sterior edge not so distinctly three-lobed: the middle part is occu-
