velvety black, with long pink bristles. Sternum and coxfe 

 dark chestnut-brown ; faices greyisli. 



Carapace longer than wide, slightly longer than patella and 

 tibia i. or iv. ; fovea deep, recurved. 



Ocular tubercle very high, twice as wide as long. Eyes 

 o£ the anterior row distinctly procuived, the anterior edge 

 of the medians at the level of the centre of the laterals, 

 the medians much the smaller, separated from each other 

 by a spaca which equals 1^ diameter, and separated about 

 two diameters from the laterals ; posterior medians not 

 much smaller than the anterior medians, and not very widely 

 separated from them, closer to posterior laterals, which are 

 much smaller than the anterior laterals and separated from 

 them by a space which is not quite equal to the long diameter 

 of the latter. 



Stridulating-organ on coxa i. consisting of very many 

 short plumose bristles, forming a triangular pad upon the 

 suture, almost touching the distal end. 



Sternum almost as wide as long, with conspicuous sub- 

 marginal sigillse. Protarsal scopula disposed as in Lasiodora 

 erytliiocythara^ mihi. Tibia i. with 1 apical spine; ii. with 

 3 apical, 1 lower, and 1 inner; iii. with 3 apical, 1 lower,

Integument of the carapace mahogany-brown, with close

Cephalothorax longer than wide, as long as patella and 

 tibia iv., much shorter than patella and tibia i. ; fovea deep, 

 strongly recurved. Ocular tubercle very high, almost twice 

 as wide as long. Eyes of the anterior row very strongly 

 procurved, the anterior edge of the medians being much 

 behind the centre of the laterals, separated from each other 

 by a space which surpasses their diameter, and from tlie 

 laterals by about two diameters ; posterior medians about as 

 large as the anterior medians, nearly at the same distance 

 from them and from the posterior laterals, which are much 

 smaller than tlie anterior laterals and separated from them by
