ON NEW AND RARE BRITISH ARACHNIDS. 75 



Laseola inornata, Cambr. 



Laseola dissimilis, Cambr., female, Proc. Dors. 

 F. Club, Vol. XXV1L, p. 84, fig. , Vol. 

 XXVIII., p. 126, and XXIX., p. 170. 

 The identity of Laseola dissimilis, Cambr., female, and 

 the female of L. inornata, Cambr., seems to be certain. 



Leptyphantes nigrescens, sp.n., pi. A, figg. 11, 12, 13. 



The adult male was contained in a collection of spiders 

 received from Dr. Carr, University College, Nottingham, 

 and found by his nephew, Mr. Lancelot Carr, near 

 Lichfield, in 1911. This genus is now very numerous in 

 species, but I believe the present to be quite distinct and 

 hitherto undescribed. In the male sex the form and 

 structure of the palpi and palpal organs furnish the 

 strongest characters for the identification of the species. 

 (For full description see postea, p. 90). 



Bathyphantes explicata, Cambr., pi. A, figg. 14, 15. 



BatJiyphantes explicata, Cambr., Bulletin Roy. 



Gard., Kew, 1911, p. 370. 



Among other spiders received in 1898 from the Royal 

 Gardens at Kew, an adult male was overlooked at the 

 time. I quite believe it to be an indigenous species. It 

 differs from all of this genus known to me in the form 

 and structure of the palpi. 



Hilaira nu big en a, Hull. 



Hilaira nubigena, Hull, Trans. Nat. Hist. Soc., 

 Northumberland, Durham, and Newcastle- 

 upon-Tyne, n.s., Vol. IV., p. 47, pi. ii., figs. 1. 

 4, 5, 6, 7, 13, 1911. 



Both sexes of this very distinct new species and fine 

 addition to our British List were received from the 

 Rev. J. E. Hull, by whom they were discovered at 

 Killhope Lane, Northumberland, in 1910 and 1911.
