ON SOME NEW AND RARE BRITISH ARACHNIDA. 91 



The falces have not the protuberant form near the base in 

 front similar to those of M. rurestris. 



The palpi have the fore extremity of the radial joint broad and 

 slightly obtusely pointed, with a small prominent point at its 

 outer side. From this point to the hinder extremity of the joint 

 is a series of minute tubercles, each bearing a slight bristle ; the 

 cubital joint has close to its fore extremity on the upper side two 

 prominent bristles near together and directed forwards. The 

 shortest and least strong of these two bristles is less than half 

 the length of the other, which is tapering and longer than the 

 joint itself. The digital joint is of moderate size and a little 

 prominent near the middle on its outer side ; the palpal organs 

 complex, in general appearance like others of this genus. The 

 paracymbium, or large irregularly formed, somewhat crescent- 

 shaped process close to their hinder extremity on the outer side, 

 is of characteristic shape. 



Abdomen jet black, slender, oval. 



The female is slightly larger and of stouter build than the 

 male, but resembles that sex in general characters. The form 

 of the genital aperture is characteristic, but somewhat similar to 

 that of M. rurestris. (See Fig. 29.) 



An example of the male of this species was received from Mr. 

 W. Falconer from Leeds in 1901 ; one of each sex from Dr. A. R. 

 Jackson from Hexham in 1902 (and also a male in 1906); as 

 well as a male from Epping Forest (Mr. W. Falconer) in 1903.

Although very nearly allied to D.fuscipes, BL, this little spider 

 may easily be distinguished by a different form of the caput, and 

 the structure of the palpi of the male. When looked at from 

 above and behind the outline of the elevation of the caput has 

 on its sides no lateral impression, being quite straight, whereas
