of abdomen pale olive-brown to brownish yellow ; carapace along 

 the borders of the interocular area darkened, with dark olive-green 

 or almost black granules; the larger granules and the crests of the 

 palps also nearly black ; anterior face of humerus blackened ; fingers 

 reddish brown to dark olive-green ; legs pale-yellow. 



Carapace depressed, somewhat longer than broad, very broad in 

 front, as long as the first and second caudal segment and half the 

 third ; anterior margin truncated or widely sinuate, rugose and 

 crenulated, not emarginate in the middle ; median groove widened 

 in front of the eye-tubercle and again anteriorly, but not forked, 

 terminated by a small concave lobe projecting from the middle of the 

 anterior edge of carapace, the widened portion of the groove some- 

 times minutely granular ; sides of carapace coarsely granular, 

 especially along the borders of the interocular area, finely granular 

 at the posterior angles ; interocular area smooth and polished, finely 

 punctate ; median eyes one-fourth of the length of carapace from 

 the posterior margin. 



Terga punctate, smooth and shining or very minutely granular 

 in the anterior part of each segment, finely granular at the sides ; 

 last segment coarsely granular at the sides ; segments 2-6 or 3-6 

 with a median longitudinal keel. 



Sterna smooth and polished, finely punctate ; the last segment 

 without keels, weakly granular posteriorly, sometimes nearly smooth 

 with only a very few mesial granules. 



Cauda sparsely granular above in the anterior segments ; the upper 

 crests granular, the terminal tooth in segments 2-4 enlarged ; 

 upper lateral keels granular, terminating posteriorly in middle of 

 fifth segment ; infero-lateral and median keels granular, weak or 

 obsolete in segments 1 and 2, distinct in segments 3-5, the median 

 keels quite and the infero-lateral ones nearly obsolete in first seg- 

 ment ; lateral and ventral surfaces of cauda granular, densely so on 

 the lower side of first two segments ; cauda shorter than the trunk ; 

 vesicle large, longer and usually considerably broader than fifth caudal 

 segment, with a few small granules at the base below. 



Palps. All the crests of the humerus coarsely granular ; its upper 

 and lower surfaces, except quite distally, coarsely and somewhat 

 thickly granular ; anterior surface with a few small and some very 

 large granules, its upper and lower edges defined by strong crests. 



the male the operculurn is completely divided into two separate chitinous plates 

 by a longitudinal cleft, and, in the adult, a pair of chitinous stylets, attached to 

 the middle of the operculum, become visible on lifting the plates from behind. 

 In the female the right and left halves of the operculum are soldered together 

 along the median line, and there are no stylets.
