440 ME. E. I. POCOCK ON SOME OLD-WOEID 



whereof the external extends almost to the anterior margin of 

 the tergite, and the internal has its posterior granule much larger 

 than the rest. 



Sternites : anterior three smooth, fourth weakly granular only 

 at the sides, the fifth weakly granular throughout and furnished 

 with four posteriorly complete, anteriorly abbreviated granular 

 keels. 



Tail moderately strong, not elongate, almost parallel-sided ; 

 intercarinal spaces weakly granular ; all the keels of the first 

 four segments strongly granular; the first segment furnished 

 with ten complete evenly granular keels, whereof the four superior 

 are more strongly developed behind than in front ; the second 

 segment also furnished with ten keels, but the median lateral 

 keel is weaker than the rest, each of the four superior keels 

 elevated behind into a large tooth, these teeth on the superior 

 keels greater than those on the superior lateral keels ; third and 

 fourth segments furnished with eight granular keels ; the superior 

 keels of the third developed behind into an enormously long and 

 strong erect tooth ; a similar, but smaller tooth on the superior 

 keels of the fourth segment ; superior lateral keels of the third 

 bearing distally a large tooth, the corresponding keel on the 

 fourth segment evenly granular throughout ; fifth segment con- 

 vex above, with a shallow median sulcus, the superior keels very 

 weakly granular, a few strong granules only close to the vesicle, 

 inferior lateral keels evenly granular throughout ; inferior surface 

 very convex, the median keel well expressed and strongly granular, 

 almost tubercular behind ; in the anterior half the granules on 

 each side of it form a single longitudinal series, and posteriorly 

 there are on each side a few irregularly arranged large tubercles. 

 Vesicle slender, granular and costate beneath, the spine well de- 

 veloped; the aculeus of the ordinary form. 



Palp. — Humerus with the upper keels granular and the well- 

 developed space between them very feebly granular ; jDosterior 

 surface with weakly granular keel ; anterior surface bearing 

 several large tubercles and a finely granular keel below. Brachium 

 above with three well-developed keels, whereof the two posterior 

 are only subgranular ; anterior surface armed with a few large 

 and sharp tubercles ; inferior surface subcostate and weakly 

 granular. Manus much rounded and swollen, wider than the 

 brachium, very feebly granular and subcostate above. Digits 

 long and slender, curved and subcostate ; the immovable digit at
