PHIDOLE. 239 



vertex ; mandibles very powerful, triangular, smooth and shining, 

 with a few fine shallow punctures, but not striate ; clypeus smooth, 

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

 riorly transverse ; antennal carinae short and divergent, continued 

 as divergent stria margining the well-marked antennal hollow or 

 groove for the reception of the scape ; this 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 raised, hut 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 above, 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, I/ slightly over 6 mm. 



Hob. I procured a single I/ on the maidan at Calcutta. It 

 was wandering about a nest of P. rliomtnnoda, with the and 

 I/ I/ of which it seemed to be on quite friendly terms.

11. Head yellowish red, antennas, thorax aud legs yellow, 

 abdomen yellow shaded with fuscous brown. Head, thorax and 

 abdomen covered with somewhat sparse, erect, pale yellow hairs. 

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

 dibles as it is broad posteriorly ; occipital emargination very 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 media 

 triangular portion slightly depressed, smooth and shining; antennal 

 carinrc short, divergent posteriorly, but continued as a margin tc 

 the long broad antennal furrow, which curves towards the eyes so 

 as to contain a portion of the flagellum as well as the scape ot 

 the antenna, the scape falls short of the apex ot the lobes 

 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 marg, 

 transverse, narrow, slightly emarginate; posterior node somewhat 

 thicker and broader, but transverse, rounded above ; abdomen 

 broadlv oval, smooth, polished and shining.
