distinctly toward the apex ; median segment longer than the

Length, 7 mm. 



Hab. Barrackpore. 



From P. Wroughtoni which it resembles in colouration it 

 may be known by being stouter, by the head being longer, 

 by the eyes being nearer each other at the top ; by the 

 pronotum not having such a gradual slope to the head, and 

 almost transverse behind, by the abdomen being shorter 

 and broader and stouter.

Black, pruinose with a plumberous hue, the apex of the 

 abdominal segments broadly black, not pruinose, the pruin- 

 osity giving the insect a greyish hue ; wings yellowish 

 hyaline, the apex infuscated. Eyes a little converging 

 beneath, ocelli moderate, not in a triangle ; the posterior 

 separated from each other by a somewhat greater distance 

 than they are from the eyes. Clypeus equally convex all 

 over, short, broad, the sides obliquely truncated, the apex 

 almost transverse ; labrum half the length of the clypeus, 

 bluntly rounded. Occiput transverse, very little developed 

 behind the eyes. Antennae moderately stout, the scape 

 greyish pruinose. Prothorax longer than the head, not 

 much narrowed towards the head, the sides a little 

 convex, at apex arcuate. Median segment concave 

 at the apex ; the sides terminating in stout, somewhat 

 triangular projections, the apex with a thick fringe of 

 pale hair. Abdomen subsessile. Radial cellule short,
