SPIDERS 



LYCOSID,E 



The members of this family are to be found 

 running freely over the ground, and carrying the 

 egg-sac attached to the spinners. Many of the 

 larger species make a short burrow in the soil and 

 there keep guard over the egg-sac. Eyes and 

 tarsal daws as in the PiiauriJ<e, with slight 

 differences.

 autumn. The female frequently excavates a re- 

 treat for herself and her egg-cocoon in the soft 

 earth. Known also under Trochosa and as Ljceia 

 agretyca, Blackwall.

AGELENID^) 



Spiders with eight eyes, situated in two trans- 

 verse rows. Legs with three tarsal claws. The 

 species of this family spin a large sheet-like web, 

 and construct a tubular retreat at the back of it, 

 which leads to some crevice amongst the rocks, 

 the roots of herbage, or the chinks in the walls of 

 outhouses, wherever the various species may happen 

 to be found. The posterior pair of spinners i* 

 usually much longer than the other two pairs. 



30. Crypbceca sihicola (C. L. Koch). 

 Teesdale (J. E. H.). 



Common in the hill districts, in the fell walls 

 and beaten from furze. Known also as Tegenaria 

 tylvicola, Blackwall. 



3 1 . Cryphceca diversa, O. P.-Cambridge. 

 Durham, Pelaw Wood (J. E. H.).

 under a stone in the spring of 1893. 



32. Garbles atropos (Walckenaer). 



Durham ; Teesdale ; Wolsingham (J. E. H.). 

 Very common under stones on the fells and in 

 woods all the year round. Adult males are most 

 frequently met with in the spring ; for the rest of the
