2-6 with a smooth longitudinal keel ; segment 7 with a low, 

 smooth, median elevation in front, minutely granular on each side 

 of this, coarsely granular laterally and on the pair of posterior 

 elevations ; behind the median elevation of seventh segment is a 

 smooth transverse depression. 



Sterna. All the segments smooth and polished, finely punctate ; 

 the last not carinate. 



Cauda rather weak ; its upper surface smooth and polished ; the 

 upper crests granular, obsolete in the posterior half of the fifth 

 segment, the terminal tooth enlarged and spiniform in segments 

 2-4 ; upper lateral crests granular, weak on segment 5, and present 

 only on the anterior half of the segment ; inferior lateral crests weak 

 in the anterior segments, smooth in the first 3 segments, weakly 

 granular in segment 4, serrated in segment 5 ; infero-median crests 

 obsolete on segments 1-3, weakly granular on segment 4, denticulate 

 on segment 5 ; ventral surface of cauda smooth, polished and finely 

 punctate in segments 1-3, nearly smooth and hollowed out between 

 the keels in segment 4, with a row of coarse granules on each side of 

 the median crest in segment 5 ; lateral surface of cauda sparsely and 

 finely granular ; vesicle smooth. 



Palps. Crests of the humerus coarsely granular, the infero- 

 posterior crest developed only in the proximal half ; upper surface 

 of humerus coai'sely granular ; anterior surface flat, large, nearly 

 as broad as the upper surface, with well-marked upper and lower 

 crests and coarsely but sparsely granular in the proximal half ; 

 lower surface of humerus with a few weak granules ; upper crest of 

 brachium composed of a row of coarse granules, posterior surface of 

 brachium with a number of low, rounded granules ; hands moderate, 

 convex above, finely punctate and shiny, the upper surface covered 

 with low, rounded, anastomosing tubercles ; finger-keel moderate, 

 nearly smooth ; the inner part of upper surface of hand with a 

 single, low, broad, longitudinal elevation extending from the base to 

 the finger, and representing the secondary keels ; outer part of 

 upper surface with a secondary keel, composed of a row of enlarged 

 granules ; width of hand scarcely exceeding the length of hand- 

 back ; inner edge of hand denticulate. 



Legs. Anterior surface of femora nearly smooth, with a few 

 minute granules, lower edge of femora granular ; tarsi very bristly, 

 the terminal tarsi of the last two pairs of legs with 1-2 external and 

 4 internal spines below, in addition to the 4 external and 5 internal 

 spines on the terminal lobes ; anterior claw of each foot very long, 

 much longer than the posterior claw ; superior terminal process of 

 iarsi very large, longer than the lateral lobes, provided with 6-8
