Portmarnock, Tallaght). Adults of botli sexes are to be found in May 

 and June. I), cornutus ranges from Dorset to ]N"orth "Wales and 

 Northumberland. Abroad it inbabits Sweden, Denmark, Germany, 

 Poland, Austria, Hungary, and north-eastern France. 



Bismodicus lifrons (BL). 



WaleTcenaera lifrons, Bl. (Spid. Gr. B. I.). 



Ulster, Connaught, Munster. 



The only known Irish localities for this spider are Islandmagee 

 and Colin Glen, county of Antrim ; Armagh ; Clonbrock, county of 

 Galway ; and Kenmare, county of Kerry. Adults from May till July. 

 The species is scarce, though widespread in Great Britain (Dorset, 

 Inverness), probably commoner in Scotland than in England. On 

 the Continent it seems a northern form, occurring in Sweden, Ger- 

 many, northern France, and northern Hungary.

This species is recorded from Ireland, by Mr. Cambridge, as 

 JV. agrestis {I.e. p. 115), under which name it appears in Mr. Work- 

 man's list. I have seen specimens from Arvagh, county of Cavan; 

 Loughgilly, county of Armagh ; and Achill Island, county of Mayo. 

 Adult male in April, females in December and January. ;S^. fuscus is 

 a widely-distributed spider in Great Britain (Dorset, Oban) and on 

 the Continent (Sweden, Eussia, Hungary, Germany, Italy, France). 



Stylo f horax retusus (WestTc.). 



Neriene rettisa, Cb. (Spid. Dorset). 



Ulster, Connaught, Leinster. 



Mr. Cambridge records this spider as Irish without definite locality. 

 I have seen specimens from Armagh, Achill Island, county of Mayo, 

 JS"orth Bull and Templeogue, county of Dublin. Adults occur both 

 in spring and autumn. Widely distributed in Great Britain (Dorset, 

 Inverness) though scarce, this species has an immense range abroad — 

 jSTovaya Zemla and Siberia to l!^orth Africa. 



1 Mr. Cambridge has shown that the use of Neriene, Bl. (of which iV. ruhens 

 is the type) for this genus by Kulczynsld and Simon cannot be followed. It seems 

 that Stylothorax (Bertkau, 1883), of which Neriene apicata, Bl. is the type, is the 

 correct generic name.
