D. lapidosus has been recorded from numerous localities in Ureat 

 Britain, but it is probable that most, if not all, of the Scottish speci- 

 mens are referable to B. cupreus. It is said to occur throughout the 

 entire Holarctic E-egion. 



JDrassodes cvpreus (BL). 



Brassm lapidosus or lapidicolens (in part) of Cambridge and other 

 authors. 



Ulster, Connaught, Munster, Leinster. 



One of our commonest spiders, occurring all over Ireland. Speci- 

 mens have been taken at numerous localities, from the counties of 

 Antrim and Donegal to Skibbereen and Berehaven in the county of 

 Cork and Slea Head, at the extreme west of Kerry ; on Lambay 

 Island, off the coast of the county of Dublin, as well as on Inishmore 

 (Aran), and Inish M'Dara, off the coast of the county of Galway, and 

 A.chill Island, county of Mayo. Males are to be observed in April, 

 May, and June, females from April till !N'ovember, being most plentiful 

 in June and July, when the young spiders are hatched from the 

 •eggs. Cocoons can then be found beneath stones, guarded by the 

 mother. In our list of Edinburgh spiders Mr. Evans and I only 

 recorded adults of this species up to August. In the south of Ireland, 

 however, they last on into November, and at Altidore, county of 

 "Wicklow, I have found a female with her newly hatched brood of 

 young so late as September. 



JDrassodes troglodytes (Koch). 



Drassus clavator, Bl. (Spid. Gr. B.I.). 



Ulster, Connaught, Munster, Leinster. 



Widely distributed, but not common. I have seen specimens from 

 Londonderry ; Portrush ; Clonbrock, county of Galway ; Killarney ; 

 county of Wicklow (Newcastle and south of Wicklow town), and 

 Drogheda. This spider with us is adult in summer ; specimens taken 

 in September are about half -grown. In Great Britain it seems scarce, 

 though widespread — Dorset, Isle of Man, Cumberland, Northumber- 

 land, Edinburgh, Oban, Aberdeen, Inverness-shire ; while abroad it 

 occurs throughout the Pal^arctic Begion from the islands of the 

 Atlantic to Mongolia. 



[The immature spider doubtfully recorded as J), delmqtiens, Cb., 

 from county of Wicklow (Dubl. Nat. F, C, 1896), is probably refer- 

 able to D. troglodytes'].
