go ON SOME NEW AND RARE BRITISH ARACHNIDA. 



The fakes are normal and similar in colour to the cephalo- 

 thorax. 



The Maxilla, labium, and sternum are yellow-brown, marked 

 irregularly with deep blackish brown. The sternum is short, 

 broad, nearly round behind, its termination slightly and abruptly 

 produced between the coxae of the fourth pair of legs. 



Abdomen oval, black, thinly clothed with coarse hairs. 



The female is of about the same size, and resembles the male 

 in colour and general characters, and her palpi have the digital 

 joint of normal form ; that is, not protuberant or like the 

 undeveloped digital joint of a male spider. 



The form of the genital aperture and process is characteristic, 

 the latter very prominent in profile. 



A female of this spider was found in 1891 near Weymouth by 

 C. O. Pickard-Cambridge, females in 1901 by Dr. A. R. Jackson 

 at Hexham, and others of the same sex at Huddersfield by 

 Mr. W. Falconer in 1902, with which latter females was the 

 only male I have seen. 



Microneta beata, sp. n. Figs. 27-31. 



Adult male, length rather less than i line. 



This species belongs to the M. rurestris section of the genus 

 Microneta, and resembles it in its slender form and other general 

 characters. The cephalothorax is brown, marked with darker 

 brown ; and there is little or no lateral impression on the 

 margins at the caput. 



The legs are orange-yellow, at times suffused on the tibiae and 

 metatarsi of the first and second pairs with brownish. The 

 height of the clypeus is about equal to half that of the facial 

 space, impressed close to the eyes, and prominent at the lower 

 margin. The eyes are normal ; the four centrals form a 

 trapezoid, whose length is rather greater than its breadth, and 

 its fore-side shortest. The space between the hind-centrals is 

 less than that between each and the lateral eye next to it.
