Thc hody is tolerably convex, ovate, totally smooth, a little 

 morc than twicc as long as broad (ol : 15). 



The head is verv broad, ncarly half as broad as the fourth 

 pereional segment (2o:50); the midth of the anterior margin 

 is feebly projecting; it is scarcely more than twice as broad 

 as long (23 : 11), not immersed; fully as long as the lirst pe- 

 reional sesment. 



The eyes are tolerably large, verv distinet, transversally 

 ovate. 



The first pair of antemue (Pl. II, fig. 22) are six-jointed, 

 the three lirst joints subequal in length, the lirst very thick 

 almost infiated, the fourth and lifth joints are subequal but 

 narrower than the third, the last joint is very minute; they 

 reach only a little beyond the anterior margin of the first 

 pereional segment. 



The second pair (Pl. 11, fig. 22) are louger and more 

 slcnder than the first, eleven-jointed, thc first joint is thick, 

 the second very short, the third to sixth subequal in length, 

 the five last ones very short, subequal, scarcely as long as thc 

 two preceding togethcr. They reach a little beyond the midth 

 of the first pereional segment. 



The labrinn is verv deep and large, rounded below, hanging 

 down as a courtain. 



The rnandibles (Pl. 11, fig. 23) are long, narrow, with the 

 free lower end almost spirally bent aroimd thc maxilla?, and 

 ending in a feebly hollowed, long tooth. Thc three-jointed 

 palp is comparatively slcnder, the first joint the longest, the 

 second much shorter, the third almost as long as the first, 

 tipped with three longer and four to six shorter bristles. 



The first pair of rnaxilloi are simple, long, slcnder as in N. 

 philippcnsis, but armed at thc tip with one strong tooth and 

 two bristles. 



The second pair are exactly of thc same building as iii 

 N. philippensis, but more soft, and armed with shorter, hookcd 

 spines.
