apophysis at its extremity on the outer eido, the point directed 

 inwards. Digital joint very large, of a broad, oval, flattish form. 

 Palpal organs prominent and complex. 



Abdomen elongate-oval, depressed, hairy ; its colour is greyish- 

 brown above, with a longitudinal, central, somewhat irregularly 

 dentated, dark blackish band, emitting some lateral, black, 

 ragged, transverse bars, edged more or less broadly and irregu- 

 larly with yellowish white on their hinder margins ; just above 

 the spinners is a large, triangular, pale, whitish area, marked 

 with two or three dark brown angular lines. Sides dark, black- 

 brown. Under side yellow-grey, spotted with black. In some 

 examples the yellow-white on the upper side prevails, but in 

 its general aspect the spider usually appears to be variegated 

 with black, dark-grey, brown, and yellow-white. 



The sexes are very similar in colours and markings. 



Mr. Blackwall records this fine species from near Lancaster. 

 I have found it myself rather abundantly at Calke Abbey, 

 Derbyshire, in the month of August, 1861, on an old wood- 

 paling fence, in the joints and crevices of which it finds a secure 

 retreat. It is not very active, and its leaping powers seem to be 

 slight. I have also received it from Norfolk and from Sussex, 

 as well as (very recently) from Hoddesdon, in Hertfordshire.
