Blackwall's name for this spider has, as we here see, prece- 

 dence of Koch's. — This species seems to be rare in Sweden ; I 

 have only met with it in Germany, at Travemiinde. 



Th. riparium approaches very near the two preceding "species, 

 Th. tepiclariorum and Th. formosnm , and together with them forms 

 a separate little group within the genus Theridium (vid. Thor., On 

 Eur. Spid., p. 93). It is widely separated from the species of the 

 genus Ero by the form of the cephalothorax and by the absence of 

 spines on the legs.

This species does not any more than Phyllonethis (Theridium) 

 lineata etc. belong to Sundevall's Steatoda, on which genus vid. Thor., 

 On Eur. Spid., p. 93. — The only Swedish locality for Th. pictum 

 mentioned by Westring, is Qvickjock in Lappland, whence I also 

 have received a specimen from Dr. H. Widegren. But I have also 

 several specimens of both sexes, which I have myself taken at Satra 

 in Westmanland. The northern specimens are perfectly similar to 

 the German from Niirnberg, which I received from Dr. L. Koch.
