sulcus beginning on the 2'"' segment, strongly developed and 

 not inesially sinuate, nearly-smooth, only very lightly rugulose. 

 The anterior furrow lightly beaded. The caudal process triangular, 

 truncate, with bifid apex. The lateral surface of the keel-bearing 

 portion of the somites closely and finely granular at the anterior 

 extremity of the body but becoming gi-adually less and less 

 strongly so towards the posterior end; the inferior keels (or 

 ridges above the base of the legs) almost absent except on the 

 2'^'', 3"^ and 4^''. Sterna deeply impressed longitudinally. Anal 

 sternite with a small tubercle on each side, not projecting beyond 

 the middle of the convex posterior border. 



Legs with a small claw, femora about twice the length of 

 tibiae, scarcely longer than tarsus and not three times the length 

 of the trochanter. 



Length 33 ; width 4 mm. 



A single female specimen from Palon. Collected by Sig. L. Fea.

9 . Colour; antennae and head black, the latter llavous below ; 

 dorsal surface of somites mesially black, the keels and the adja- 

 cent area of the tergite pale yellow ; on the Ijlack median band 

 there are traces of a fine fiavous band on each side; lateral 

 surface with its upper half l)rown, lower half flavous; legs and 

 sternal areas flavous. 



Upper surface of segments smooth but not highly polished, 

 granular above the base of the keels in the anterior end of the 

 body. Keels small, anterior border and angle small, convex, 

 lateral margin considerably tliickened; posterior angle acute, 

 produced, surpassing the posterior border of the tergites on all 

 the segments. Transverse sulcus strong, not sculptured, mesially 

 angled, extending from the 5*^' to the 18*; anterior constriction 

 deep, finely beaded. Lateral surface finely granular; inferior 

 crest present only on the anterior segments. Caudal process with 

 acute and long apical tubercles.
