This species is very unmistakable. Hence the absence of synonyms. 



For the sake of those who have not access to C. Koch's work, I 

 give the following short diagnosis : 



Colour J upper surface piceous, rufo- or olivaceo-piceous ; legs and 

 caudal vesicle clear yellew, ochraceous, or ferruginous. 



Cephalothorax usually about as wide as long, sometimes a little 

 longer than wide or vice versa ; in ? as long as the 1st + 2nd + 3 

 of 3rd caudal segments, in c? a very little longer than the 1st -f- 2nd ; 

 the frontal lobes and sloped lateral portions sharply granular, the 

 upper portion mostly smooth ; the ocular tubercle in the middle or a 

 little behind the middle, manifestly cleft, smooth, the eyes small, 

 separated by a space a little less than a diameter ; the lateral eyes 

 sub-equal in size, either nearly evenly spaced or (usually) the pos- 

 terior more separated from the median than the anterior. 



Tergites more or less finely granular postero-laterally, the last more 

 coarsely granular, with sometimes indications of the lateral keels. 



Sternites entirely smooth. 



Tail robust, in c? about 3| or of the length of the cephalothorax, 

 in ? a little more than 3^, the superior and supero-lateral keels 

 denticulate or granular, the lateral area sparsely granular, the lower 

 surface of the first 3 segments entirely smooth, of the 4th granular 

 or sub- denticulate on the keels, the 5th with strongly denticulated 

 keels and a few sharp tubercles on the inter-carinal areas ; the vesicle 

 moderately large, furnished beneath with strongly granular keels. 



Palpi robust in $ , generally more slender in 6 , the humerus 

 sparsely but coarsely granular above in the proximal two-thirds of 

 its surface, the keels in front and behind denticulate ; hrachium sub- 

 costate and rugulose, sometimes weakly granular above, denticulate 

 in front; maiins covered above with smooth, rounded, sometimes 

 slightly anastomosing tubercles, the inner border denticulate, the 

 lower surface sparsely but coarsely granular, some of the granules 

 forming two distinct series or keels ; the upper surface either convex 

 or nearly flat, the sharpness of the inner edge varying with the con- 

 vexity, the area immediately above the keel of the 'hand-back' 

 nearly at right angles to the plane of the upper surface and more or
