Full-grown male specimens of "Ph. anreolus Blackw." and" Ph. 

 cespiticolis id." sent me by Cambridge, I can distinguish from each 

 other only by the inferior process of the tibial joint being in the 

 former abruptly truncated straight across at the apex, but in the 

 latter very obliquely, so that the process is nearly triangular. From 

 Dr L. Koch I have also received specimens of what he calls Ph. au- 

 reolns and Ph. cespiticolis , completely agreeing with those sent me 

 by Cambbidge under the same names. Of the males in my collec- 

 tion (partly from Sweden and partly from Germany) I have been 

 able, by means of the characteristics thus given by the inferior pro- 

 cess of the tibial joint, to refer some to "Ph. anreolus" and others 

 to "Ph. cespiticolis ;" but some specimens are transition-forms between 

 both, and which I cannot with certainty class as belonging more to 

 the one than to the other of them The females of these "Ph. anreolus" 

 and "Ph. cespiticolis" I am quite unable to distinguish. I am there- 

 fore very much inclined to believe that they are not specifically dif- 

 ferent. Blackwall's figure of the palpi of his "Ph. cespiticolis" d 1 

 exactly suits "Ph. anreolus" cf: for in that figure the inferior 

 process of the tibial joint is quite rectangularly, not obliquely trun- 

 cated. — That Clebck's Ar. anreolus, as well as Sundevall's and 

 Westbing's Phil, anreolus, comprises both these so-called species, ap- 

 pears to me certain; but that Ph. cespiticolis Walck. (on which see 

 also the next article. Ph. cespiticolis Westb.) is the same as Ph. ce- 

 spiticolis Cambe. and L. Koch, is not equally sure: Westbings "Ph. 

 cespiticolis Walck." is at least quite another species, and the same 

 as Ph. auro-nitens Auss. 



The ground-colour of the female varies from dark brown to 

 light yellow, and the markings are also very diversified. I possess 

 several specimens of this species from North Germany, Austria and 

 Switzerland, which perfectly agree with the Swedish. The form "au- 

 reolas" appears to be the most common in Sweden, whereas the Ph. 

 cespiticolis of Cambridge and L. Koch seems to be rarer. — See also 

 next species.
