Cephalo- thorax blackish In-own, minutely punc- 

 tured. Legs pale yellow. Abdomen black. A rare 

 species. 



Entolecara erythropus Westr. ( // 'ah h na, t a 

 , rythropa in " Spiders of Dorset.'') 



Length of male, 2 mm. 



The radial joint of the male palpus is of a curious 

 form, consisting of two branches, which when viewed 

 from above have the appearance of the letter F.

Enteleeara thorellii Westr. ( Walckmaera 

 fastigata Bl.) 



Length of male, 2 mm. 



Cephalo-thorax dark brown. Legs yellowish red. 

 Abdomen brownish black. The cephalic lobe is 

 very prominent and distinct. 



Entslecara trifrons Cb. ( Walckenaera tri- 

 r rons in " Spiders of Dorset.") 



Length of male, 2.2 mm. 



Very similar in general form to E. thorellii, but 

 easily distinguishable by the form of the radial joint 

 of the male palpus, which will be figured. 



GENUS EVANSIA CAMBR. 



The anterior row of eyes is slightly curved, its 

 convexity being directed backwards. The posterior 

 row is strongly curved, its convexity also being. 



directed backwards. The eyes of this row are equi- 

 distant, and almost equal in size. Legs with coarse 



, strongest upon the femora. Tarsi of fourth 

 pair .>f legs much longer than the metatarsi. 



Evansia mersns ( lb. 



Length. Male 2.2=; mm. 



Cephalo-thorax pale brown. Abdomen dark brown, 

 with a darker central stripe and several pale markings 

 towards its posterior part. Legs yellow, tinged with 

 orange. 



A single specimen of this spider was discovered by 

 Mr. W. Evans in 1899. 



GENUS DIPLOCEPHALUS BERTKAU. 



Posterior eyes in a straight line, or in a slightly 

 curved row, having its convexity directed backwards ; 

 equidistant, or the space between the centrals slightly 

 less than that between one of them, and the adjacent 

 lateral. Anterior eyes in a straight or nearly straight

line. Tibias with long erect bristles. The cephalo- 

 thorax of the male in many species is of a most curious 

 conical form, the apex of the projection bearing the 

 anterior central eyes, and having, upon its upper 

 surface, a projection bearing the posterior central 

 eyes.
