This species, younger individuals of which Sundevall has con- 

 founded with Ph. (Artanes) fusco-marginatus (De Geer). is nearly 

 related to Ph. aureolus, and probably sometimes not easily distin- 

 guished from it. A $ jun. has been sent to me by Westring, and 

 I have myself found a couple of adult specimens in Upland A cT 

 and a Q from Germany have also been kindly communicated to me 

 by L. Koch under the name of Ph. auro-nitens Auss. 



The Ph. cespiticolis of Walckenaer — or Ph. cespitum Walck., as 

 it ought to be called ') , — considered by Westring as identical with 

 this species, is a very uncertain synonym, and I think it is not im- 

 possible that it is only a variety of Ph. aureolus, perhaps the 

 same that by Cambridge and L. Koch is called Ph. cespiticolis (see 

 preced. spec). Walckenaer takes up as synonyms to it: Thom. 

 Mstrio Latr. 2 ) and Philodr. collimis C. Koch 3 ) , from works that 

 I have not had the opportonity of consulting. He also quotes (er- 

 roneously) Phil, fusco-marginatus Sund. under his Phil, cespitum or 

 cespiticolis. Westring's Ph. cespiticolis is not, as Walckenaer's simi- 

 larly named species is said to be, distinguished from Ph. aureolus 

 by a "moins bombe et plus large" cephalothorax. — In order to avoid 

 further confusion, I have thought it best to give Westring's spider 

 the name under which it has been described by Ausserer: Ph. 

 auro-nitens. 



In colour Ph. auro-nitens closely resembles the darkest varie- 

 ties of Ph. aureolus: the cephalothorax is dark brown, with a broad 

 pale central band, and usually also a short, thick, V-formed white
