Misaki agree well with Forel's description. The long epinotal spines 

 are distinctly divergent and the funicular joints 2-7 are broader than 

 long. These characters serve to distinguish the species from the 

 closely allied P. pungens Mayr of Ceylon and Malacca.

This ant (Plate XLI, Fig. 12), which is known to occur also in Burma 

 and Ceylon, was originally described by Cameron from Nagasaki. Later 

 Mayr showed that it is hardly more than a variety of the Samoan 5. 

 godeffroyi, from which it differs in having curved instead of straight 

 mandibular blades. I have before me a number of workers and a 

 few dealated females collected by Mr. Hans Sauter in the following 

 localities: Negishi, Kanagawa and Yamanaka (1700 ft.). According 

 to a note accompanying the specimens they were taken "in siftings 

 in pine woods. "

I have not seen the typical form of this species, which is allied 

 to the Australian and Indian I. glaber Mayr. It differs mainly in 

 the structure of the epinotum, the basal surface of which "is much 

 longer than in glaber, nearly twice as long as broad, with a transverse 

 impression which makes it appear a little concave in profile. The 

 declivous surface is more inclined than in glaber; it is not longer than 

 the basal surface nor overhung by its posterior edge." The types 

 are from Osaka.
