124 NEW AND RARE BRITISH SPIDERS. 



the sides and under side arc mixed yellowish and grey on a dark 

 yellowish-brown to blackish ground. 



The female resembles the male in general characters and mark- 

 ings, but is altogether lightly coloured, though the white pattern on 

 the abdomen is less distinct, the hairs forming it being more of a 

 dull yellowish than white colour, and the sides of the abdomen 

 have several more or less distinct oblique black stripes. The palpi 

 are yellow, and the form of the genital aperture is very distinct and 

 characteristic. The relative length of the legs appears to differ 

 from that of the male, being 3, 4, 1, 2. 



Adults of both sexes of this fine addition to our British spiders 

 were sent to me in June, 1888, by Colonel Le Grice, by whom they 

 were found at Folkestone in that month. It appears to be an 

 exceedingly active spider, and the extent of its leaps is wonderful. 

 It lives among stones and rubbly chalk near the shore, and comes 

 out during the hot sunshine. The very striking pattern on the 

 abdomen will serve to distinguish it a glance from all our other 

 British Salticids. It is common in many parts of France, Switzer- 

 land, and Germany.

Male. The cephalothorax is oblong-oval, truncated in front, of a 

 flattened form, with the hinder slope not very long, biit moderately
