292 MR. R. E. TURNER OX THE [Feb. 15, 



convex and rather broadly truncate at the apex ; median segment 

 rounded a, little longer than broad. Abdomen elongate, the sides 

 nearly parallel, the segments not strongly convex above ; segments 

 2-4 marked with a depressed transverse line close to the base, 

 but not appreciably constricted ; the segments closely and rather 

 shallowly punctured ; the basal segment longer than the breadth 

 at the apex, with a longitudinal sulcus from the base to beyond the 

 middle. Seventh dorsal segment narrow, much longer than broad 

 and very narrowly rounded at the apex, the apical half rugose. 

 Hypopygium small, without basal spines, ending in a spine which 

 alone projects beyond the dorsal segment and is sometimes feebly 

 recurved. Second recurrent nervure received by the third cubital 

 cell just before one-third from the base. 



Black ; the mandibles (except at the apex), clypeus, the margins 

 of the eyes very broadly, narrowing on the inner margin and not 

 quite reaching the summit, the band on the outer margin more 

 narrowly continued and undulating on the posterior margin of the 

 head, the interantennal prominence, the margins of the pronotum, 

 the pleurae, coxae beneath, tegula? and a line above them, a spot 

 bifurcate anteriorly on the disc of the mesonotum, scutellum, post- 

 scutellum, an oblique band curved at the apex on each side of the 

 median segment and a broad transverse band, broadly interrupted 

 in the middle, on both dorsal and ventral segments 1-6 of the 

 abdomen, represented on the first ventral segment by a triangular 

 spot, yellow ; the seventh segment and the femora, tibia?, and tarsi 

 dull ferruginous. Wings hyaline, with a small fuscous cloud at 

 the apex of the radial cell ; nervures fuscous, the stigma fusco- 

 ferruginous. 



Length 14-15 mm. 



2 . Mandibles rather broad and flattened, pointed at the apex ; 

 the clypeus small, without a carina. Head half as broad again as 

 long, rounded at the posterior angles, smooth and shining, with a 

 longitudinal frontal sulcus and a large shallow depression on each 

 side reaching more than halfway from the base of the antenna? to 

 the vertex. Thorax and median segment closely and rather finely 

 punctured ; the pronotum twice as broad as long, nearly as broad 

 as the head, the sides nearly parallel ; scutellum not very narrow, 

 rounded at the apex ; median segment very short, obliquely trun- 

 cate posteriorly. Abdomen broader than the thorax ; the first 

 segment with a broad, shallow, transverse groove close to the apex, 

 the second segment with four strong transverse carina? and the 

 apical margin raised ; the first, third, fourth, and fifth segments 

 closely and finely punctured and covered with short greyish 

 pubescence. Pygidium truncate posteriorly, narrow at the base 

 but not contracted at the base of the truncation, the surface of the 

 truncation elongate-ovate with three longitudinal carina? at the 

 base, the apex smooth and shining ; the hypopygium extending 

 far beyond the epipygium. Fifth ventral segment rugose. 



Black ; the flagellum, the tibia? and tarsi, the dorsal surface of 

 the first abdominal segment, the sides of the other segments, and
