This active spider is of frequent occurrence in the woods of 

 North Wales, running with great rapidity among the foliage of 

 the trees, and sometimes concealing itself under the lichens 

 which grow upon their trunks and branches. In June the female 

 deposits about 157 spherical eggs of a pale yellowish white co- 

 lour, not agglutinated together, in a lenticular cocoon of white 

 silk of a very fine texture, measuring y^ths of an inch in dia- 

 meter ; it is inclosed in a sac of the same material, attached to 

 the inferior surface of a leaf, the sides of which are curved down- 

 wards and are held in that position by silken lines connecting 

 them with the sac. The female generally places herself on or 

 near the cocoon, but speedily abandons it on being disturbed.

According to Dr. Leach this spider has been taken once in 

 England, near Cheltenham. See the Supplement to the 4th, 5th

Specimens of this handsome species have frequently come under 

 my observation when exploring the woods and commons of Den- 

 bighshire. In July the female constructs a cell of white silk of 

 a compact texture among the stems of gorse, heath, or the leaves 

 of plants, which she curves about it and secures in that position 

 by means of silken lines. In this cell she deposits about 140 

 eggs of a deep yellow colour, not agglutinated together ; they are
