truncation finely rugulose. Abdomen elongate-conical, the 

 first segment truncate at the base ; sixth ventral segment 

 with a spine on each side at the apical angles ; seventh dorsal 

 segment produced into a flattened plate, longitudinally striated 

 and narrowly truncate at the apex. Hypopygium with a 

 spine on each side near the base and another at each of the 

 apical angles and a strong apical spine, obliquely striated 

 above. First ventral segment not carinate and not separated 

 deeply from the second. Third abscissa of the radius half as 

 long again as the second; first recurrent nervure received 

 rather near the apex of the second cubital cell, second at one- 

 quarter from the base of the third cubital cell. 



Black; the orbits of the eyes interrupted at the summit 

 and a small spot on each side on dorsal abdominal segments 

 4-5 and of ventral segments 2-5 pale yellow ; the spots on 

 the dorsal segments sometimes absent. Wings pale fusco- 

 hyaline, nervures black. 

 Length 24, exp. 39 mm. 



? . Clypeus transverse, punctured, without a carina ; 

 mandibles falcate, deeply grooved above. Eyes not touching 

 the base of the mandibles ; the antennae inserted further 

 from each other than from the eyes; a deep shining depres- 

 sion above the base of the antennae, extending to the eyes, 

 but not reaching halfway to the vertex. Head deeply and 

 closely punctured, more than half as broad again as long, 

 somewhat flattened, the vertex broadly smootli and shining. 

 Pronotum coarsely punctured, with an obscure, longitudinal, 

 median carina, about one-third broader than loug, rectangular, 

 the anterior margin with a row of long hairs; scutellum 

 small, finely punctured and clothed with long hairs ; median 

 segment shorter than the scutellum, smooth and shining and 

 obliquely truncate posteriorly. First abdominal segment 

 truncate anteriorly, the dorsal surface finely and closely 

 punctured, clothed with long hairs in the middle, the apical 

 margin narrowly depressed; second segment with about 

 twelve transverse carina?, low at the base, increasing in height 

 to the apex, segments 3-5 smooth and shining ; ventral 

 segments shallowly punctured, the fifth coarsely longitu- 

 dinally striated. Pygidium truncate posteriorly, sharply 

 contracted at the base of the truncation, the dorsal plate 

 trilobed, with arched carina? at the base, the lateral lobes 

 almost straight on the outer margin, the angles slightly 

 prominent ; ventral plate projecting beyond the dorsal, 

 rounded, with an emargination at the apex, the lateral 

 margins feebly serrate. Anterior tibia? strongly emarginate 

 at the apex, intermediate tibia? thickened, the first joint of the
