eyes remarkably large and prominent, situated above the middle of 

 the head. Thorax rather long, the pro- and rnesonotum forming 

 one convexity subequal with the metanotum forming the other 

 convexity, the meso-metanotal suture dividing them broad and 

 well-impressed. Node of pedicel somewhat thick, inclined for- 

 wards ; abdomen broad and short, anteriorly somewhat truncate 

 and gibbous, with a very distinct groove for the reception of the 

 node. 



Length, 3-5 mm.

$ . Head and abdomen brownish yellow, thorax dull reddish 

 yellow, antennae and legs dingy yellow of a lighter shade than the 

 thorax ; head, thorax and abdomen lightly minutely punctured,

 abdomen, less so to the thorax. Head rectangular, the sides 

 straight, a little longer than broad, posteriorly slightly emarginate ; 

 mandibles finely sculptured, armed with 6 teeth ; clypeus polished 

 and shining, very convex and subcarinate down the middle, with 

 the margin anteriorly slightly emarginate ; antennae long, but not 

 so long proportionately as in P. lonyicornis, the scape passing 

 beyond the top of the head by about one-fourth of its length ; 

 eyes not prominent, placed about the middle of the sides of the 

 head and a little to the front. Thorax in profile somewhat re- 

 sembling the thorax in species belonging to the genus Iridomyrmex, 

 Mayr ; the thoracic suture distinct but feeble, the meso-metanotal 

 suture slightly emarginate, and containing t\vo somewhat pro- 

 minent stigmata; metanotum raised a little, the basal portion 

 passing by a short and rounded curve to the apex. Pedicel as in
