Genera of the Scoliidte. 477 



truncate, a smooth obliquely depressed triangular truncation 

 from the centre to the apex. Head closely and rather finely 

 punctured, most closely on the front ; the inter-antennal 

 prominence absent, only represented by a small tubercle on 

 each side above the base of the antennai ; eyes widely and 

 rather deeply emarginate ; the ocelli small, the posterior pair 

 rather nearer to tlie eyes than to each other. Aiitennie as 

 long as the thorax and median segment combined ; the scape 

 shining, very sparsely punctured beneath and no longer than 

 the third joint of the ^agellum; the joints cf the tlagellum 

 gradually increasing in thickness to the apex, the apical 

 joint nearly twice as thick as the basal. Thorax deeply but 

 sparsely punctured, the mesopleurge more coarsely punctured ; 

 pronotum a little shorter than the mesouotum, considerably 

 narrowed anteriorly ; scutellum large and subtriangular, very 

 narrowly truncate at the apex. Median segment a little 

 shorter than the scutellum, almost vertically truncate at the 

 apex, more closely punctured, with a longitudinal depression 

 in the middle, the sides rugose. Abdomen slendtr, tapering 

 slightly at the extremities, about one quarter longer than the 

 head, thorax, and median segment combined ; the basal 

 segment smooth and shining, depressed anteriorly, with a 

 short petiole ; the other segments deeply but sparsely 

 punctured, broader than long; the seventh dorsal segment 

 deeply and narrowly emarginate at the apex for the reception 

 of the long recurved aculeus ; the ventral segments shining, 

 with a few fine scattered punctures. Radial cell more than 

 two and a half times as long as its greatest breadth, extending 

 for about two-fifths of its length beyond the third cubital 

 cell; the stigma a little more than half as long as the radial 

 cell on the costa. Second cubital cell rhomboidal, more than 

 twice as long on the cubital as on the radial neivure, the 

 third cubital cell twice as long as the second on the radial, 

 and more than half as long again on the cubital nervure ; 

 the two recurrent neivuies received slightly beyond the 

 middle of the second and third cubital cells. 



Bh.ck, with sparse white pubescence; the mandibles 

 (except at the apex), a triangular mark at the apex of the 

 clypeus, a minute spot above the base of each antenna, the 

 pronotum with a large black mark reaching from the anterior 

 margin to beyond tlie middle, the tegul^e, a broad transverse 

 band at the apex of dorsal abdominal segments 1-6 slightly 

 sinuate anteriorly on the first segment, the tibise, tarsi, and 

 the apex of the femora yellow ; the first dorsal abdominal 

 segment and the second more obscurely, ferruginous.. Wings
