364 BRITISH oeibatidj:. 



Colour bright chestnut-brown. 



Texture polished in appearance, really very finely 

 punctured. 



Gephalo thorax rather small and not very clearly 

 marked off from the abdomen. Rostrum rather small- 

 pointed but not sharp ; slightly trifid. Rostral hairs 

 large, curved, set far back. Lamellas long narrow- 

 blades on edge, narrower at the distal than the proximal 

 ends ; no cusps. Translamella a mere line, not con- 

 spicuous. Lamellar hairs rather long, setiform, directed 

 forward almost horizontally. Pseudo-stigmata hidden 

 by the advancing corners of the abdomen. Pseudo- 

 stigmatic organs with slender peduncles of moderate 

 length and more or less recurved fusiform heads. Inter- 

 lamellar hairs very long, setiform, almost perpendicular. 

 Tectopedia well developed. Apodemata joined to the 

 sternum. 



Legs rather short, fourth pair not reaching the hind 

 margin. Femora with blades ; each front tibia has a 

 large rounded elevation in the anterior end of the 

 median line from which the tactile hair springs. Glaivs 

 monodactyle. Tactile hairs to all the legs ; most joints 

 bear a whorl of slightly thickened or fine curved hairs 

 near the distal extremity, tarsi thickly clothed as usual. 



Abdomen rather long, not very round posteriorly ; 

 progaster very slightly undulated ; the antero-lateral 

 angles project very much and are rounded ; there is an 

 inward (concave) curve behind them, and then they are 

 carried back and fade into the notogaster. Notogaster 

 plain, without markings, but with a row of very fine 

 hairs near the margin, and two longitudinal rows of 

 similar hairs nearer the median line. Genital and 

 anal plates at opposite extremities of the ventral plate, 

 the former small, pentagonal, with the point forward ; 

 the latter large and almost square. 



Distribution. — Generally distributed, chiefly found 

 in dead leaves and moss ; it has doubtless usually been 

 mistaken for N. tibialis.
