little-known British Spiders. 167 



Palpi very characteristic and quite similar in the two 

 speciineiis. 



Centromerus sf/lvaticus, Bl. 



Tineticus sylvaticus, Bl., Camb., List of British & Irish Spiders, 1003. 

 Tineticwi serratus, Camb., Proc. Dorset Nat. Hist. & Antiq. Field 

 Club, vol. xxviii., 1907, pp. 143-144, pi. B, tigs. 45-48 (female onlj). 



Centromerus prudens, (lamb. 



Tmeticus prudens, Camb., List of British & Irish Spiders, 1900. 

 Tineticus serratus, Camb., Proc. Dorset Nat. Hist. & Antiq. Field 

 Club, vol. xxviii., 1907, pp. 143-144, pi. B, figs. 45-48 (male only). 



I have examined the British examples of the supposed 

 C. serratus, Camb. The male is C. prwiens and the female 

 G. si/lvaticus. They differ markedly from the true 0. serratus, 

 of which 1 possess French examples, and which, among other 

 things, is a very much smaller spider. 



Centromerus siinilis, Kulcz, 



Tmeticus similis, Kulcz., Camb., Proc, Dorset Nat. Hist. & Antiq. Field 

 Club, vol. xxvi., 1905, pp. 02-63, pi. A, figs. 12-13. 



I have examined this small female, which is unknown to 

 me, though certainly ei Centromerus. It is not, 1 believe, 

 C. similis, Kulcz., and more closely resembles C. incilium, 

 Li. Koch ; but, since it has not been compared with that 

 species, I do not advise altering the name under which it 

 stands on the British list at present. 



Micryphantes rurestris, C. L. Koch. 



Microneta rurestris, C. L. Koch, Camb., List of British & Irish Spiders 



1900. 

 Eupolis e.vcavata, Camb., Proc. Dorset Nat. Hist. & .Intiq. Field Club, 



vol. xxi., 1900, pp. 26-27, pL, figs. 7 «, b, c, d. 



I examined the type-female of E. excavata. In my opinion 

 this is certainly a decolourize i female of M. rurestris, C. L. K. 

 The depression at the occiput is, I believe, due to trauma. 



Micryphantes heatus, Camb. 



Microneta beata, Camb., Proc. Dorset Nat. Hist. & Antiq. Field Club 

 vol. xxvii., 1906, pp. 90-91, pi. A, figs. 27-31. ' 



Bathyphantes explicata, Camb., Proc. Dorset Nat. Hist. & Antiq. B"'ield 

 Club, vol. xxxiii., 1912, p. 75, pi. A, figs. 14 & 15. 



The type of B. explicata exactly resembles M. heatus in
