 short close pile ; the middle joints thicker than the basal 

 and apical ones ; the 3rcl and 4th joints nearly equal, the 

 others becoming gradually shorter ; the colour black. 

 Head black, small, narrower than the mesothorax, the 

 front depressed, smooth and shining, the sutures scarcely 

 visible, the clypeus truncated at apex, the labrum rounded. 

 Thorax red, a small spot on the fi-ont of the mesonotum, 

 the posterior half of the sternum and of the pleuras (except 

 above) black; the cenchri Avhite. Abdomen much longer 

 than the head and thorax, rounded, black, Avith a bluish

 tarsi grooved, punctured ; the basal joint of the tarsus is 

 as long as the other four ; the tarsus itself being longer 

 than the tibia ; the calcari are short. Wings longer than 

 the body, narrow. The first marginal cellule is rather 

 narrow, longer than the second ; the nervure is straight 

 and issues from near the apex of the long thin stigma. 

 The first submarginal cellule is small ; the second is 

 double the length of the first, and has a small horny point 

 near its centre ; the third is more than double the length 

 of the second, and is very slightly Avider at the apex than 

 at the base ; the fourth is shorter than the third, and is 

 considerably Avidened at the apex. The first recurrent 

 nerA^ure is receiA^ed a little in front of the second sub- 

 marginal cellule ; the second in the basal fourth of the 

 third. The colour is blackish, with a hyaline space a
