pointed in front, and of a red-brown colour. Abdomen black, 

 flattish, and very hairy ; the legs rather short and robust. The 

 sexes are alike in colours. 



The radial joint of the male palpus has a strong, tapering 

 sharp-pointed apophysis at its outer extremity ; the digital 

 joint is of moderate sizo, and the palpal organs are simple, with 

 two or throe not very conspicuous processes at their fore 

 extremity. 



I mot with both sexes of this spider in 1 859 on the sand hills 

 near Southport, Lancashire, in early summer, running in sun- 

 shine. I have also more recently received it from Lord 

 Walsingham, by whom it was found near Merton Hall, Norfolk. 



PBOSTHESIMA LUTETIANA. 



Melanophoba ltjtetiana, L. Koch, Die. Arachn. Fam. der. 

 Drassidon, p. 15, pi. vi., fig. 100. 



Adult female, length 3 lines. 



Nearly allied to Prodhesima nigrita, Fabr., but larger. The 

 oephalo-thorax is deep brown, the logs aro of a rather lighter 

 colour, with tho oxtromitios gradually palor still, and of a 

 reddish-brown hue. The abdomen is dark blackish-brown, the 

 pubescence being apparently of a somewhat yellow- brown tint. 

 The form of the gonital aporture boars some resemblance to that 

 of P. nigrita, but is still noticeably distinct, consisting of a 

 longitudinal channel or furrow which divides abruptly, at its 

 posterior extremity, into two strongly divergont portions of equal 

 size. 



An example of this spider was sent me latoly from Dunnoon, 

 Scotland, by Mr. H. 0. Young, of Glasgow; and several others 

 immature, but considered by Mons. Simon to be probably of this 

 species, were recoived some years ago from Mr. W. Farren, by 

 whom they were found in Wickon Fen, Cambridgeshire.
