vertex ; mandibles very powerful, triangular, smooth and shiniDi,^ 

 with a few tine shallow punctures, but not striate ; clvpeus smooth, 

 the medial portion broadly triangular, well-defined posteriorly, ante- 

 riorly transverse : antennal carinte short and divergent, coutinued 

 as divergent striae margining the well-marked antennal hollow or 

 groove for the reception of the scape ; tiiis latter somewhat coarsely 

 sculptured within ; antennae short and slender, the scape falling 

 short of the top of the head by more than one-third of its length : 

 eyes small, placed in the anterior half of the head. Thorax : the 

 pro- and mesonotum form one convexity, not raisyd, but slightly 

 convex above, the pro-mesonotal transverse groove barely indicated, 

 the transverse ridge or carina behind it obsolete ; the basal 

 portion of the metanotum short, slightly convex above, the 

 metanotal spines very acute and erect. Pedicel : the 1st node 

 fine, narrow but transverse, and not emarginate aliove, without 

 appendix beneath ; 2nd node from above subquadrate, as broad as 

 long, the angles rounded and the sides not produced into cones ; 

 abdomen depressed, broadly oval. 



Length, 1/ slightly over 6 mm. 



Hah. I procured a single 1/ on the muidan at Calcutta. It 

 Avas wandering about a nest of P. rhombinodn, with the ^ ^ and

%. Head yellowish red, antenna?, thorax and legs yellou-, 

 abdomen yellow shaded with fuscous bro\A^n. Head, thorax and 

 abdomen covered with somewhat sparse, erect, pale yello\A' hairs. 

 Head remarkably narrow and long, twice as long without the man- 

 dibles as it is broad posteriorly ; occipital emargination verv deep 

 and narrow, the posterior lateral angles of the head very blunt 

 and rounded ; head longitudinally striate, more distinctly on the 

 anterior half, the apex of the posterior lateral lobes smooth and 

 shining ; mandibles sparsely punctured ; clypeus with a medial 

 triangular portion slightly depressed, smooth and shining; antennal 

 cariniB short, divergent posteriorly, but continued as a margin to 

 the long broad antennal furrow, which curves towards the eyes s.j 

 as to contain a portion of the flagehum as well as the scape of 

 the antennae, the scape falls short of the apex of the lobes of 

 the head by about one-third of its length. Thorax emarginate in 

 profile at the meso-metanotal suture ; the pro- and mesonotum 

 form one convexity, the pronotum laterally tuberculate ; meta- 

 notal spines short, erect, acute. Anterior node of the pedicel 

 without appendix beneath, in profile triangular, upper margin 

 transverse, narrow, slightly emarginate ; posterior node somewhat 

 thicker and broader, but transverse, rounded above : abdomen 

 broadly oval, smooth, polished and sliining.
