 hoei from China (Cliefoo). 



Spirostreptoidea. 

 Alloporus sulcatulus, sp. n. 



? . Colour of body and head deep black ; antennas and 

 legs reddish yellow. 



Head with deep frontal groove; rugose above, coarsely 

 wrinkled between the antennas and the adjoining area, smooth 

 just above the labial margin ; distance between the eyes 

 rather less than the diameter of an eye ; eyes acutely angular, 

 internally composed of about 52 ocelli arranged in about 8 

 transverse series. 



Antennas moderately long, segments gradually decreasing 

 in length from the second to the sixth. 



First tergite wrinkled, punctured and irregularly sulcate 

 above and at the sides ; lateral process much enlarged, pro- 

 duced forwards into a large rounded angle, with a deep mar- 

 ginal sulcus, above which there is another very strong sulcus 

 following nearly the same curvature, with a third strong 

 sulcus on its postero-inferior angle. The rest of the segments 

 with posterior part separated by a distinct groove from the 

 anterior, and strongly though somewhat irregularly longi- 

 tudinally sulcate from base to summit, as well as ornamented 

 with less definite sculpturing, the sulci becoming fainter 

 towards the hinder end ; but anteriorly the areas that they 

 define become at the sides of the body cariniform or tubercu- 

 liform, as in Lophostreptus ; anterior part of segments trans- 

 versely cristulate behind, smoother in front ; sterna smooth. 



Pores small in the middle of the posterior part of the 

 segments. 



Anal somite. — Tergite punctulate and rugose, scarcely 

 angular ; valves with thickened and strongly sulcate margin j 

 sternite with posterior border nearly transverse. 



Number of segments 47. 



Length about 70-75 millirn., width 7. 



Loc. Giriama, near Fuladoya. A single female specimen.
