SPIDERS OF NORTHUMBERLAND AND DURHAM : 



SOME NOTES OF RECENT CAPTURES. 



Rev. J. E. HULL,

The records here set forth are supplementary to those contained 

 in my ' Catalogue of the Spiders of Northumberland and 

 Durham' (Natural History Transactions of Northumberland, 

 Durham, and Newcastle-on-Tyne, Vol. 13, Part 1). In that list 

 192 species were recorded for the two counties. The additions 

 now made will bring- the total up to 210, nineteen species being- 

 added and one removed. 



Of these nineteen, one is new to science. 



Diplocephalus spinosus sp. n. Nearly allied to D. permixtus 

 Cb., but may be distinguished by the following- characters : 

 Cephalothorax, leg's, and palpi yellowish, clouded with 

 black ; abdomen almost black, clothed with dark hairs. 

 Cephalic lobes, clypeus, and situation of eyes, as in D. per- 

 mixtus, but the transverse furrow is deeper, the lobes are 

 yellowish tinged with black at the summits, and the eyes 

 are situated on black spots. The tibial process of the 

 palpus is somewhat similar to that of D. permixtus, but has 

 three spines instead of two. 



A sing'le adult male was found among moss at the edge 

 of a bog- on Plenmellor Common, July 1901. 



Tapinopa unicolor Cb. (Prpc. Berwicksh. Nat. Club, Vol. 7, 

 No. 2, p. 317). Must disappear as the name of a separate 

 species, becoming- a synonym of T. longidens Wid. (Pickard- 

 Cambridg'e, k List of British and Irish Spiders,' 1900). Of 

 this form of T. longidens I took an adult female in June of 

 this year. 



The other eighteen species which have turned up since the 

 publication of my list in [896 are as follows : 



Clubiona brevipes Bl. Adult male, Haltwhistle. 



Agroeca brunnea Bl. Fairly common among the heather on 

 the fells. 



Hahnia mo'ntana Bl. In woods, near Feather-storie Castle. 

 Hahnia nava Bl. Two females, Feajtherstone. 

 Pedanostethus arundinetus Cb. Haltwhistle. 

 Taranucnus setosus Cb. Boggy places, near Haltwhistle.
