anteriorly, anterior margin raised and produced at lateral angles. 

 Median segment rounded, with a fine longitudinal sulcus from 

 base, finely punctured at base, very finely rugulose before apex, 

 extreme apex smooth. First abdominal segment obliquely con- 

 cave, truncate anteriorly, segments 2-5 with a strongly impressed 

 transverse line near base, all the segments closely and shall owly 

 punctured above, more finely and sparsely beneath. First seg- 

 ment beneath deeply parted from second at apex, with a strong 

 median carina, produced at apex into a blunt tubercle; second 

 segment with an indistinct median carina. Hypopygium with 

 a prominent tubercle on each side near base, thence narrowly 

 produced, sides almost parallel, conical at apex with a short spine. 

 Black; anterior margin of face and clypeus, narrowly interrupted 

 in centre, and a small spot at base of mandibles on the outer side 

 yellowish-white. Wings fusco-hyaline, nervures black. Length 

 14-17 mm. 



£, Clypeus transverse, with a very short median carina from 

 base, not reaching apex. Head wider than thorax, broader than 

 long, strongly rounded at posterior angles, convex, shining and 

 "very sparsely punctured, a short longitudinal sulcus between 

 antennae; front round base of antennas concavely depressed. Pro- 

 notum about twice as broad as long, anterior margin straight, 

 finely and sparsely punctured. Mesothorax and median segment 

 sparsely punctured, median segment short and obliquely truncate 

 posteriorly. First abdominal segment strongly punctured, with 

 a transverse carina before apex, apical margin slightly recurved. 

 Second segment with five transverse carinas, including the 

 recurved apical margin, the carinas irregular and broken on sides. 

 The remaining segments and all segments beneath smooth at 

 base, punctured at apex; fifth segment beneath coarsely rugose. 

 Pjgidium narrow, elongate, about four times as long as wide, 

 rounded at apex, lateral margins subparallel; strongly depressed 

 and almost vertically truncate; a median carina from base of 

 truncation reaching to apex, lateral margins also raised, forming 

 marginal carinas. At base of truncation are one or two delicate
