side, situated just in front of the transverse sulcus but on the 

 posterior higher smooth portion of the tergite ; the hinder edge 

 of the tergites, at least in the posterior two thirds of the body, 

 armed with a series of fine, distinctly separated teeth; sterna 

 striolate. Anal tergite angled above, not projecting beyond the 

 valves; valves convex, margins simple and not compressed; 

 sternite large, with convex margin. Legs with a single seta on 

 the lower surface of eacli segment. 



No. of somites 45. 



Length 32 mm. 



A single example (immature 9 , with the 4 posterior somites 

 apodous) from S. Tenasserim (E. W. Gates). 



This species differs from all hitherto considered in possessing 

 8 labral punctures. In this respect it comes near the Javan 

 heteroporus of Porath but it may be at once distinguished by 

 the presence of the minute denticles along the hind margins of 

 the tergites. 



14. Spirolbolus feae , sp. n. 



Closely allied to S. spiculifer. 



Colour black, the posterior border of the tergites with a red- 

 dish tinge ; antennae and legs ochraceous. Head smooth , with 

 median sulcus; 6 or 8 labral pores. Eyes of large size, separated 

 by a space about equal to twice a diameter. Antennae very 

 short, much shorter than head. Collum laterally evenly narrowed, 

 projecting nearly as low as the second tergite. The lower sur- 

 face of the 2."'^ produced into a strong downwardly directed 

 process on each side. The rest of the tergites smooth behind 

 on the dorsal side, thickly marked with crescentic, semicircular 

 or horse-shoe shaped impressions behind. The transverse sulcus 

 nearly obsolete, represented by shallow transverse depression. 

 Pore situated behind this depression ; the lateral part of the 

 tergites obliquely striate in front, longitudinally striate behind. 

 Anal tergite smooth above or nearly so, produced behind into 

 a posteriorly rounded caudal projection, which just surpasses the
