OBTAINED IS EGYPT AND THE SOUDAN. 301 



green ; legs and lower surface of tlie trunk quite pale, the palpi 

 with tlie coxa, trochanter, and femur pale, the tibia, manus, and 

 digits (except the tips) strongly infuscate. 



Carapace resembling that o£ dimidiatus, except that the 

 interior median crests are represented by two distinct oblique 

 rows of granules, the posterior of which is not continuous with 

 the posterior median crest. 



The tergites resemble those of dimidiatus. The tail is like 

 that of dimidiatus in the development of its keels, the median 

 lateral crest being imperceptible on the 4th and almost absent 

 on the 3rd segment ; but the tail differs very noticeably in the 

 thickness of its anterior segments, these being normal in JayaTcari 

 and not so thickened as in dimidiatus ; consequently the tail appears 

 to be more parallel- sided. The diff"erence in the narrowness of 

 the 1st segment may be estimated by the fact that in dimi- 

 diatus its width is equal to the length of the 3rd segment, whereas 

 in JayaTcari it is very much less {cf. measurements). 



Sterna like those of dimidiatus, the external of the four keels 

 on the 5th being either about half the length of the internal or 

 about two-thirds. 



Chelce like those of dimidiatus but more thickly hairy, and 

 with the inferior median crest on the brachium obsolete ; hand 

 a little wider than brachium, its width less than length of hand- 

 baek, which is less than half the length of the movable digit ; 

 digits scarcely sinuate, the movable furnished with 16-17 median 

 rows of teeth, the teeth of the internal series not far removed 

 from the apices of the median rows behind them and lying well 

 behind the middle of the rows that pass in front of them. 



Legs hairy, crests on the femora granular, on the rest of the 

 segments smooth ; feet armed below with two parallel series of 

 short, close-set spines, there being 5 on each row on the anterior 

 foot and 8 on the posterior ; some similar but rather larger 

 spines, which gradually pass proximally into slender setae, occur 

 upon the distal tibial segment. 



The pectines are furnished with 33-34 teeth and extend 

 beyond the apex of the coxa. 



In the S the digits are basally lobate but still contiguous, 

 and the hand is a trifle wider than in the 5 . The pectines, 

 moreover, extend to the distal apex of the 4th trochanter and 

 have 39-41 teeth.
