 S. blackwallii Thor. {Drassus blackwallii). 



A house-frequenting spider, sometimes found wandering on the 

 walls and ceilings of rooms and outhouses, ur in crannies of walls ; 

 reported from eight widely separated English counties, Edinburgh 

 and Leinster ; abroad it is rare, occurring in France, under bark 

 and in wall crevices, and in Austria and Hungary. AditU, q May and 

 June, 2's linger on to late summer and autumn. First occur-

 Gen. Episiitiis Walck., 1-2

All British examples were referred to this aggregate until the Rev. 

 O. Pickard Cambridge* showed that there were two species included 

 under this name in Britain, Ihe other being E. lugubris Sim., and 

 that they are almost equally distributed. An adult is needed to 

 allocate the undermentioned specimens to its segregate. Episiniis 

 is very rare in Ireland, much commoner in the south of Great Britain 

 than in the north, but extending into Scotland ; widel}' distribTated 

 in Europe. Adult in summer.

 furze.

 through the county, but recorded stations few or none in the hillier 

 districts of the west. Infrequent in the Huddersfield area, Bury 

 Mill and Royal Clough, Scammonden ; but Lepton Common, 

 abundant on furze. 



T. impressuiii L. Koch. 



Very much resembling the last, but less vividly marked, this spider 

 escaped notice as a British species until 1903, f but is now on 

 record for Warwickshire, Dorset, Hereford, Cheshire and the 

 Grampians ; abroad, noticed in Holland and South Russia. Season 

 as in T. sisypliium Clerck.
