Genus Peremptor, gen. nov. 



Head much produced and grooved in front, and longer at 

 the base of the antennae than at the vibrissas. Eyes bare, 

 widely separated, small, about half the length of the head. 

 Fronto-orbital bristles stopping at the bases of the antennae. 

 Cheeks and facial ridges bare ; vibrissas considerably above 

 the level of the mouth. Antennas very short, the third joint 

 not much longer than the second ; second joint of the arista 

 quite short, the third minutely pubescent. Proboscis and 

 palpi long. Abdomen oval, the middle segments without 

 discal setae. Pirst posterior cell open, and ends rather before 

 the tip of the wing ; the posterior cross-vein is nearer to the 

 margin than to the chief cross-vein ; the length of the last 

 section of the fifth posterior vein is less than a sixth of the 

 length of the preceding section. 



This genus differs from Miltogramma in the head not being 

 swollen, the facial ridges not being thickened, the antennas 

 being exposed, the vibrissas being well developed, as well as 

 by the shape of the abdomen, and the small eyes.
