Céphalothorax with its frontal portion nearly flat and sparsely beset 

 with some larger and smaller granules, the anterior border slightly 

 emarginate in the middle; the ocular tubercle situated in the anterior 

 half of the céphalothorax , smooth and undivided, the lateral eyes sub- 

 equal in size and in contact, a series of granules separates the ho- 

 rizontal frontal portion from the depressed lateral portion, which is 

 finely and sparsely granular; the post-ocular portion sparsely granular, 

 deeply sulcate longitudinally in the middle, the median sulcus twice 

 branching transversely, once in the middle of its distance and again 

 at its hinder end. 



Abdomen; tergites finely and sparsely granular with a single larger 

 tubercle on each side of the middle line on the posterior border; the 

 last tergite with two such tubercles in front of the posterior border, 

 of which the lateral is the termination of a series of granules; ster- 

 nites smooth, finely punctured; stigmata circular or subcircular. 



Tail moderated slender, slightly thicker at the base than at the fifth 

 segment; 1 st segment smooth beneath, the inferior and lateral inferior 

 keels obsolete , the lateral median keel fully developed and sub-granular, 

 the lateral superior and the superior strongly developed and granular; 

 the 2 nd like the l 3t except that the lateral median keel is entirely absent 

 and the lateral inferior visible, but weakly and sparsely granular ; the 

 3 nd like the 2 nd , but with the lateral inferior keels still more developed 

 and the inferior keels appearing; the 4 th like the 3 Qd , but with the 

 lateral inferior and the inferior still more developed so that it is fur- 

 nished with eight sub-tubercular keels and a slight indication posteriorly 

 of the lateral median keel; 5 th segment with five complete keels, the 

 three inferior of which are denticulate and the superior granular, the 

 lateral median keel incomplete behind: the circum-anal border of the 

 5 th segment is also denticulate ; the intercarinal spaces of the tail are 

 weakly granular , and the upper surface of the segments only shallowly 

 excavated. Vesicle large, smooth, pyriform, tapering gradually to a 

 point posteriorly, the aculeus very short and lightly curved. 



Palpi; humerus finely and sparsely granular, its anterior and upper 

 surfaces also furnished with tubercles ; brachium subcostate posteriorly, 

 smooth posteriorly and beneath , granular and tubercular in front ; ma- 

 nus wider than , but not twice as wide as the brachium , much longer 

 than wide, furnished above with three equal keels which take their 

 origin from the immovable digit, the keels and the spaces between
