The description given by Sundevall of what he considers as 

 the chief form of his L. pusilla, is too indefinite to admit of its 

 being with anything like certainty referred to the same species as 

 his "Var. ^ ," which is undoubtedly the male to L. pusilla Westr. 

 Sundevall has probably under the name of L. pusilla confounded two 

 or more species: it seems however to us reasonable, as one of them 

 can with certainty be recognized, to let that one retain the specific 

 name pusilla, the oldest by which the species has been described, 

 and that which Westring in his "Forteckning" (p. 37) and I in my 

 Kec. crit. (p. 107) restored, with rejection of the newer specific names 

 fuliginea, signata and pratensis. As surely as Blackwall's L. pratensis 

 is = L. hortensis Sund., Westr., so surely is L. fuliginea Blackw. 

 identical with L. pusilla Sund., Westr. Cambridge has sent me from 

 Eugland both cf and 9 of this species , under the name of L. fuli- 

 ginea Blackw. It appears to me certain , that Blackwall committed 

 an error, when he catalogued, as a synonym for his L. pratensis, the 

 spider which Eeuss, C. Koch and Walckenaer describe under that 

 name, but that Westring and Menge were right in identifying with 

 their L. pusilla or Blackwall's L. fuliginea the L. pratensis of Keuss , 

 Koch and Walck. I am however not perfectly sure, that the spider 

 described by Menge as the male of his L. pusilla is really so: its palpus 

 appears to me too simple and too nearly similar to that of L. frute- 

 torum C. Koch. See also the preceding species, L. hortensis. 



Specimens of L. pusilla Sund. , both cf and 9 > I nave collected 

 in Germany at Pyrmont etc.
