NEW AND BARE BRITISH SPIDERS 57 



A single adult female was taken by my son, Mark Reginald, 

 at Fenham, Northumberland, in May, 191 1. 



Cnephalocotes incurvatus Cb. (?) 



Plate II., fig. 10. 



Female. — Total length, r86 mm. Abdomen greenish black, 

 broad oval, with the usual four impressed reddish spots on the 

 anterior half. Underside a trifle paler, with two parallel 

 longitudinal rows of pale spots. The rust-coloured indurations 

 are present only in front of the spinners and on either side of the 

 genitalia. The general characters are those of Cnephalocotes, 

 and the only tangible specific character is the structure of the 

 epigyne. In this it approaches most nearly to C. pit stilus, and 

 the general form — as will be seen from the figure — is suggestive 

 of Lophocarenum rather than of Cnephalocotes. The most dis- 

 tinctive features are a pair of tiny reniform openings towards 

 the posterior margin and very wide apart. 



This spider is identified with C. incurvatus only con- 

 jecturally. It corresponds with the male sufficiently well and 

 seems to occupy the same geographical area. Two specimens 

 were taken in 19 10 — one by Mr. W. Flowers on the coast 

 sandhills near Cresswell, Northumberland, in June ; the other 

 by myself on the sandhills at Findhorn in August. The latter 

 is now in the possession of the Rev. O. Pickard-Cambridge, 

 who agrees with me in thinking that it is probably the missing 

 female of C. incurvatus Cb.
