A HISTORY OF NORFOLK 



ATTIDiE 



The spiders of this family may be recognized in a general way by their mode of progres- 

 sion, consisting of a series of leaps, when alarmed. More particularly they may be known by 

 the square shape of the cephalic region and the fact that the eyes are arranged in three rows 

 of 4, 2, 2 ; the centrals of the anterior row being much the largest and usually iridescent. 

 Otherwise these spiders are simply specialized Chiiionids, with two tarsal claws and other 

 minor characters possessed in common with members of this latter family. The commonest, 

 Salticus scenicus, will be well known to all observers, running and leaping on the walls of houses 

 in the bright sunshine.

Also known under Hentz's generic name 

 Epihlemum. 



47. Marptusa muscosa (Clerck). 

 (O. P.-C.) ; Norwich (F. P. S.). 



One of the largest and most beautiful of our 

 Attida^ often abundant under the bark of old 

 wooden palings, or among the loose stones of 

 walls, such as those which cross the down- 

 lands. 



48. Attus: puhescens (Fabricius). 

 Norwich (F. P. S.). 



49. Attus caricis, Westring. 



(O. P.-C.) ; Merton Hall (Lord Walsingham). 

 Very rare ; both sexes found on rushes in 

 a marshy spot.

5 1 . Dendryphantes hastatus (Clerck). 



(O. P.-C.) ; Drayton Drewray (F. Edw.irds). 



PISAURIDiE 



Spiders with eight eyes in three rows, and three tarsal claws. The first row of eyes 

 consists of four small eyes which are sometimes in a straight line, sometimes recurved and 

 sometimes procurved. Those of the other two rows are situated in the form of a rectangle 

 of various proportions. Pisaura runs freely over the herbage carrying its egg-sac beneath its 

 sternum, while Dolomedes is a dweller in marshes and swamps. 



52. Pisaura mirabilis (Clerck). 



(James Edwards) ; Norwich (F. P. S.) ; Cromer, Ormesby Broad and West Runton (H. W. F.). 

 Known also as Dolomedes, or Ocyale, mirabilis. 



LYCOSID^ 



The members of this family also have eight eyes, similarly situated to those of the 

 Pisauridie, but the first row is straight. Tarsal claws three. The spiders are to be found 

 running freely on the ground and carrying their 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. 



53. Lycosa ruricola (De Geer). 



Norwich (F. P. S.) ; Watton (H. W. F.) ; 

 Mousehold Heath and Ridgland (J. Ed- 

 wards). 

 A very common species. The male has a 

 claw at the end of the palpus. 



54. Lycosa terricola (Thorell). 



(O. P.-C.) ; Norwich (F. P. S.)!; Watton (H. 

 W. F.). 

 Also very common. The male has no claw 

 at the end of the palpus. 



55. Lycosa spinipalpis, F. P. -Cambridge. 



Ormesby Broad (H. W. F.). 



Females only have been taken of this rare 

 species ; the males may be known by the 

 cluster of spines beneath the tibia of the pal- 

 pus. These three species are also known 

 under the generic name Trochosa. 



56. Lycosa leoparda (Sundevall). 



(O. P.-C.) ; Ormesby Broad (H. W. F.).
