 emarginate ; apex of mandibles red ; prothorax angularly 

 emarginate posteriorly ; wings with a broad, dusky, apical 

 band, 3rd submarginal cell narrowed at the top ; abdomen 

 elongate, Ij times as long as the thorax, apical segment 

 beneath narrowly rounded at the apex, very convex, 6th 

 notched at the apex, with an impression on each side of 

 the notch, 5th almost entire, not depressed in the

2 , head and thorax with a silvery gloss ; apical 

 margin of the clypeus slightly emarginate, slightly 

 raised and margined at the sides, largely and irregularly

So like (jihhus that it is only necessary to point out the 

 distinguishing characters. 



(? difi'ers in having the 5th and 6th segments of the 

 body beneath longitudinally depressed, the 4th emargi- 

 nate, the 5th deeply and squarely notched, and the 

 6th trilobate, the central lobe slightly emarginate at the 

 apex. 



$ differs in having the clypeus very smooth and 

 shining in front, its margin not raised at the sides, and 

 with only two stiff sette projecting from above the 

 glabrous margin ; the apical segment of the body is much 

 more densely covered with black hairs, and the 3rd sub- 

 marginal cell is more triangular.
