? . — Colour black (when dry banded with pale green), the 

 lower half of the face ochraceous ; antennae and legs testaceo- 

 fuscous. 



Face smooth, with a strong transverse groove between the 

 eyes. 



Collum with its inferior portion strongly narrowed and 

 reaching behind the gnathochilarium almost to the base of 

 the first pair of legs, the anterior border of this lateral portion 

 strongly emarginate, deeply sulcate, like the rest of the 

 segments. The rest of the segments with a very deep and 

 complete transverse sulcus, the area behind which is dorsally 

 elevated and for the most part smooth, but laterally it is 

 strongly striate or ridged nearly up to the pore in the front of 

 the body, but not so high behind, while the area behind it is 

 transversely ridged from summit to base and is furnished with 

 a fine median dorsal carinule. Pores conspicuous, situated 

 above the middle of the body and nearly halfway between 

 the sulcus and the posterior border. 



Anal tergite scarcely at all produced behind, its posterior 

 border being widely rounded ; valves convex, with edges not 

 compressed ; sternal plate widely convex. 



J . — Thinner than the female, the collum laterally stouter, 

 the second segment of the mandible squared and notched, and 

 a small tooth-like outgrowth on the promentum of the gnatho- 

 chilarum ; the legs of the first pair long, thick when seen 

 from behind, but rather slender in profile. The protruded 

 portions of the copuUitory apparatus consisting of two pairs 

 of processes — an anterior, each half of which is thickly clotiied 

 internally and for half its length externally with long setaj, 

 and a posterior pair, which consists of two simple, shorter, 

 tongue-like pieces. 



Number of segments in female 58, in male 55.
