balf tbe length of the head, and not extending beyond the 

 collum. 



First tergite nearly smooth, at most very finely punctiilate ; 

 very vs'idely rounded laterally, with a conspicuous marginal 

 sulcus. Second tergite flat below or even a little excavated. The 

 rest of the somites very finely transversely striolate in front ; 

 the inferior part above the legs longitudinally striolate, tbe 

 striae in front of the transverse sulcus being directed obliquely 

 upwards; the transverse sulcus visible inferiorly, becoming 

 obsolete above and losing itself in a shallow transverse depres- 

 sion, which separates the anterior dorsal part from the posterior 

 dorsal part of the somite ; the dorsal part finely punctulate or 

 minutely striolate. Sterna transversely striate. Scohina ex- 

 tending to about the 23rd somite. Fores conspicuous, situated 

 above the middle of the side in a line with the sulci, the sulci, 

 however, curve round them posteriorly ; there is, moreover, a 

 faintly marked stria running from the pore backwards to the 

 hinder border of the somite. Anal somite small ; tergite ob- 

 tusely and roundly angled, not projecting beyond the summit of 

 the valves ; valves lightly compressed, with margins simple ; 

 sternite more than twice as wide as long, with convex posterior 

 border. 



JOegs short and thick, with a single seta below each segment ; 

 those at the anterior end of the body thickened, with the coxae 

 slightly produced. 



The anterior median lamina of the copulatory feet flat, nar- 

 rowed inferiorly, with lightly sinuate sides, the apex widely 

 rounded, the anterior lateral laminae not extending inferiorly so 

 low as the median, but surpassed by the posterior lateral. 



Number of segments 44. 



Length about 32 mm.
