posterior border ; median groove enlarged in front of the median 

 eyes, distinctly forked anteriorly, the triangular area long and nearly 

 smooth, the T-shaped depression behind the median eyes with a few

Terga very minutely granular, the segments nearly smooth in the 

 middle and furnished with a longitudinal keel ; last segment coarsely 

 granular at the sides and behind, with traces of lateral crests, finely 

 granular on the low, broad, median elevation in front. 



Sterna smooth and polished, finely punctate, the last segment 

 without traces of keels. 



Gaud a moderate ; the upper surface granular in segment 1, nearly 

 smooth, with a few minute granules in segments 2-4, smooth in 

 segment 5 ; upper crests granular, the terminal tooth enlarged in 

 segments 2-4 ; upper lateral crests granular, absent from the 

 posterior half of fifth segment ; infero-lateral and median keels 

 smooth in segments 1-3, granular in segment 4, serrated in segment 

 5 ; lateral surfaces of cauda smooth and polished in segments 1 and 

 2, sparsely and finely granular in segments 3 and 4, coarsely granular 

 in segment 5 ; vesicle smooth. 



Palps. All the crests of the humerus well developed, coarsely 

 granular, the upper, lower, and anterior surfaces also coarsely 

 granular, the lower posterior crest reaching to near the distal end of 

 the humerus ; upper crest of brachium nearly smooth ; anterior 

 surface of brachium finely granular, the posterior surface with 

 several smooth and granular crests, weakly granular between the 

 crests ; hands large, cordate at base, the inner part of the upper 

 surface depressed, very moderately convex, thickly covered with 

 punctate anastomosing elevations, which are scarcely raised above 

 the level of the surface, without a trace of secondary keels ; outer 

 part of upper surface of hands coarsely granular, with traces of a 

 secondary keel in the distal part ; finger-keel strong, smooth ; inner 

 edge of hand bluntly granular ; width of hand considerably exceeding 

 the length of hand-back. 



Legs. Anterior surface of femora finely granular, the lower edge 

 coarsely so ; tarsi of the two last pairs of legs with 2-3 external and 

 5-6 internal spines below, in addition to the 4 external and 5 internal 

 spines on the terminal lobes ; the superior process shorter than the

 not cleft longitudinally. 



Pectines with 19 teeth, scape rounded at the base behind and free
