Westring considers Linne's synonym as uncertain, but most assu- 

 redly without sufficient reason. In the above cited passage, Lin- 

 ne's description of A. bipunctata is as follows: "A. abdomine globoso, 

 atro, punctis chiobus excavatis. Habitat in fenestris. Rete disperse- " 

 all which fully agrees with the species before us. The subsequently 

 made addition in the 2 ncl Ed. of the Fauna Suecica (p. 486): "per 

 thoracem et abdomen ducitur linea ... ad anum usque sordide testa- 

 cea," is certainly founded in error, for no spider, which Linne's de- 

 scription with that addition suits, can be said to "habitare in fene- 

 stris" in this country. — Already in 1765 the species was very fully 

 and well described by Strom (loc. cit.) under the appellation of "Ar. 

 bipunctata Linn." — Linne's Ar. qitadripunctata is the same as Drassus 

 serioeus Sund., Westr. (Z>. medius L. Koch) , of which more hereafter. 



Phrurolithus ornatus C. Koch (loc. cit.) is without question 

 nothing more than" the young of Steatoda bipunctata, as has been 

 also assumed by Blackwall. Theridium thoracicum Hahn (Die Arachn., 

 I, p. 88, fig. 66), which Walckenaer ') places among the synonyms 

 of this species, as well as of his Titer, tmiste {Lithyphantes dispar 

 (Duf.)), certainly belongs to neither, but is probably a species 

 of Erigone or Walckenaera ( Micryphantes). — Ar. nocturna Linn. 

 ( = Pytiionissa maculata C. Koch) has been erroneously taken up as a 

 synonym of this species by C. Koch (Die Arachn., XII, p. 99). — St. 

 bipunctata, according to Blackwall 2 ), is also found in North America.
