104 ON BRITISH ARACHNIDA. 



Tmeticus affinis, Blackw. 



Neriene affinis, Blackw., Spid. Great Brit, and Ireland, 



p. 259, PI. xviii., Fig. 175 (1864). 

 Tmeticus leptocaulis, Menge, Preuss. Spinnen, p. 185, 



PI. 35, Tab. 85, 1866. 



Examples of this species were received from Hornsea, 

 sent to me by Mr. T. Stainforth in June, 1908. It is widely 

 distributed, but has as yet turned up very sparingly where 

 found. 



Gen. MENGEA, F. O. P.-Cambridge (for 

 Pedina, Menge, pre-occupied) = Tmeticus, 

 Cambr., ad partem. 



Mengea Warburtonii, Cambr. 



This species has been recently met with in East Yorkshire 

 by Mr. W. Falconer. 



Gen. OREONETA, Kulcz = Tmeticus, Cambr., 

 ad partem. 



Oreoneta fortunatus, Cambr. 



A rare and very distinct species (see lists in several past 

 vols. of Proc. Dors. N.H. and A.F. Club), confined, as at 

 present known, to S. Dorset. It will hardly retain its 

 position in the genus Oreoneta when its characters have been 

 more closely studied. An adult male and female were 

 found at Bloxworth on iron railings in October, 1908, and 

 adult females running on the ground on June loth, and 

 22nd on walls at Bloxworth Rectory. 



Gen. CENTROMERUS, Dahl. = Tmeticus, 

 Cambr., ad partem. 



Centromerus rivalis, Cambr. 



Adults of both sexes were received from the Rev. J. E. 

 Hull, Northumberland, in May, 1908.
