Philodromus cespiticolens. Walck. Hist. Nat. des Insect. Apt. t. i. p. 555. 



This species occurs in woods in Denbighshire. In July the female fabricates 

 a cell of compact white silk among the leaves growing near the extremities of 

 the stems of shrubs, curving them about it and retaining them in that position 

 by means of silken lines. In this cell, which she usually occupies, she con- 

 structs two lenticular cocoons of white silk, of a delicate texture, depositing 

 in each from 40 to 100 spherical eggs of a pale yellow colour. The cocoons 

 frequently differ considerably in size, the larger one measuring about \ih of an 



inch in diameter.
