Genus CLUBIONA, Latr. 

 Spiders usually of a yellowish or reddish yellow colour, 

 generally without distinct abdominal patterns, (C. compta and 

 C. covticalis are striking exceptions). The tibial apophysis of the 

 male is very variable in form. The epigynal armature of the 

 female is, as a rule, obscure, specimens of this sex being often 

 very difficult to identify specifically. The genus is well repre- 

 sented in Epping Forest, eight out of the fifteen British species 

 having been taken within its boundaries. 



Clubiona terrestris, Westr. — Common over the whole of 

 of the Forest, including Edmonton Marshes. It is usually 

 found under debris and flood-refuse. 



. Clubiona grisea, L. Koch. — Males have occurred, but 

 rarely, in several localities. 



Clubiona reclusa, Cb.— A male taken at Theydon Bois. 



Clubiona corticalis, Walck.— Not uncommon at several
