witli the so-called scobina, t^c. Probably most nearly related to 

 S]). crchrcstriatus of Humbert, whicli it somewbat resembles in sculp- 

 turing and in possessing the so-called scobina. It may, however, be 

 recognised by the much greater convexity of the margins of the 

 anal valves, and by the strongly -angled border of the anal stcrnite, 

 and by the diflerences of colour. 



Spirobolus longicolUs, sp. n. 

 (PL ii, fig. 10.) 

 Colour (in alcohol) ; pale testaceous throughout, the anterior half 

 of the somites only being of a deeper greyish tint. 



Head nearly smooth, the face marked with a short longitudinal 

 sulcus ; two widely separated pores on each side of the labral region ; 

 eyes widely separated, composed of about 30 indistinctly defined 

 ocelli ; antennce very short, scarcely reaching to the margin of the 

 coUum. 



Somites without scobina ; collum punctured throughout, produced 

 laterally beloiu the inferior extension of the succeeding somite, 

 narrowed to a rounded apex with convex posterior border and 

 straight anterior border, the apex and the anterior border as high as 

 the eye defined by a groove, the rest not sulcate ; the second and 

 succeeding segments divided into an anterior and posterior portion 

 by a groove ; the posterior portion is more elevated than the anterior, 

 punctured and obscurely and irregularly striolate above, longitudinally 

 striate at the sides, the anterior portion marked laterally and 

 inferiorly with oblique close-set strise, which becoming more and 

 more curved dorsally, eventually pass into elliptical and crescentic 

 areas on the upper surface ; pores, all on a level above the middle of 

 the side, in the posterior half of the somites well behind the trans- 

 verse groove ; anal somite punctulate, the upper surface produced 

 posteriorly into a stout, blunt, cylindrical, slightly down-turned 

 caudal process which projects a little beyond the anal valves ; mires 

 convex with strongly but narrowly compressed borders ; siernite 

 transversely elongate, with nearly straight hinder border. 



Legs slender, with a single seta on the under surface of each 

 segnnent. 



Number of segments 38 or 40 ; length about 28 mm. 

 Two female specimens from Punduloya (Mr. Green).
