carina with interantennal prominence, on which there is a very 

 fine longitudinal carina. Head finely rugulose on front, finely 

 punctured on occiput. Thorax finely rugulose, densely punctured 

 on disc of mesonotum, scutellum elevated with a depressed trans- 

 verse line at base. Median segment obliquely truncate from 

 postscutellum, surface of truncation concave. Abdomen punc- 

 tured above and beneath, elongate-conical, first segment obliquely 

 truncate anteriorly, concave at base and narrowed, as broad at 

 apex as second, beneath prominent in middle, subtuberculate, 

 with a triangular truncation at apex. Sixth segment with a 

 spine at apical angles beneath. Dorsal plate of apical segment 

 longitudinally striated, rounded at apex; hypopygium trans- 

 versely striated above, with a spine on each side near base, 

 thence gradually narrowed, terminating in a slightly recurved 

 apical spine. Black; mandibles except at apex, clypeus, two 

 oblique lines between antennas, margins of eyes interrupted at 

 apex yellow; base of fourth and the whole upper surface of the 

 following abdominal segments flavo-ferruginous. A little thin 

 grey pubescence on head and on sides of median segment. Wings 

 fusco-hyaline at base, hyaline at apex. Length 19-28 mm. 



9. Head smooth on vertex, front and clypeus punctured, 

 clypeus with a very short carina at base; a densely punctured 

 space between the antennas clothed with fulvous pubescence. 

 Pronotum as broad as head, nearly twice as broad as long, 

 slightly narrowed and broadly emarginate on posterior margin, 

 smooth and shining, with a few scattered punctures, a row of 

 punctures along anterior margin with long fulvous hairs; a large 

 but not deep depression on each side of pronotum, touching 

 anterior margin. Mesonotum and median segment, sparsely 

 punctured, median segment short and vertically truncate pos- 

 teriorly. First abdominal segment vertically truncate anteriorly, 

 pubescent at base, with two transverse carinas before apex and 

 apical margin recurved. Second segment with about eleven 

 transverse carinae, including the recurved apical margin, basal 

 carinas curved to centre, leaving a few interrupted ones at sides 

 near base; the remaining segments sparsely punctured above,
