outwardly near its apex, the second very strongly curved out- 

 wardly near its base ; the second cubital cell is half as long on 

 the radial nervure as the third. 



Black ; the apex of the fifth abdominal segment and of the 

 pygidium testaceous, the tegul^e testaceous brown. Wings hyaline, 

 the apex very faintly tinged with fuscous ; nervures fusco- 

 ferruginous.

5 . Mandibles rather deeply incised on the outer margin ; the 

 clypeus opaque at the base, with a carina from the base to the 

 middle, clothed with short, fine, silvery pubescence, very broadly 

 rounded or almost truncate at the apex, the apical margin broadly 

 smooth and shining. The second joint of the llagellum equal in 

 length to the third and more than twice as long as the first. 

 Eyes separated on the vertex by a distance eqiial to the length of 

 the second and half of the first joints of the flagellum. Head 

 opaque, the front clothed Avith very short silvery pubescence. 

 Pronotum very steeply sloped, much higher in the middle than at 

 the sides ; the mesonotum microscopically punctured, depressed 

 in the middle anteriorly, the sides and posterior margin clothed 

 with very pale golden pubescence. Median segment opaque, with 

 short transverse strife at the apical angles, vertically truncated 

 posteriorly, the face of the truncation transversely striated, with 

 a longitudinal sulcus from the base to the apex. Abdomen sub- 

 opaque, the apical margins of the four basal segments with bands 

 of silver-grey pubescence, broadly interrupted in the middle on 

 the fourth ; the pygidial area almost pointed at the apex, long 

 and narrow, shining and sparsely punctured at the base, finely 

 punctured and clothed with short, pale, fulvous pubescence at the 

 apex. The first recurrent nervure is received almost as far from 

 the second as from the base of the second cubital cell ; the second 

 is moderately rounded outwardly. The second cubital cell is much 

 longer than the third on the cubital nervure and equal to it in 

 length on the radial nervure, the third transverse cubital nervui-e 

 oblique and scarcely curved, the radial cell short and broad, 

 obliquely ti-uncate at the apex. 



Black ; the mandibles, the scape beneath, and the anterior 

 femora and tibiae beneath fu.sco-ferruginous, the apical margin of 

 the abdominal segments narrowly testaceous. Wings hyaline, 

 faintly tinted with fuscous at the apex, most strongly in the 

 radial cell ; nervures black, the stigma fusco-ferruginous. 



Length 10 mm.
