palpal organs simple, but prominent, situated far back beneath, 

 the digital joint and extending also beneath the radial. 



Abdomen, rather elongato-oval, of a dull greyish or yellow- 

 grey hue, bordered laterally on the upper side with a broadish 

 but dull brown band, and with a longitudinal central tapering 

 one of a reddish brown or blackish hue. Sides and under side 

 dull clay-coloured yellow. 



The sexos do not differ greatly in colours and markings ; but 

 the dark marginal border on the upper side of the abdomen of 

 the female is darker and better defined than in the male, and the 

 central band is rather obsolete, or else forms only a short oblong 

 marking at the fore extremity. 



Both sexes were found on a wall at Freshwater, Isle of Wight,

 from St. Helena, and other distant localities. It seems, there-

 ish-brown one. Legs strong, 1.4.2.3., especially those of the first 

 two pairs, provided with hairs and strong black spines, of a yellow- 

 ish-brown colour, with a longitudinal black line along the upper 

 part of the femora, genua, and tibiso. Abdomen oviform, 

 pointed at the spinners, and densely clothed with short, yellowish- 

 brown hairs, interspersed with long black ones. A faint red- 

 brown line passes from the spinners along the middle of the 

 upper side for more than half its length, and then separates into 

 two diverging branches, which run to its fore extremity, form- 

 ing a very acute angle ; those red-brown lines have an obscure
