THREE NEW ANTS FROM MEXICO AND 

 CENTRAL AMERICA.! 



By William Morton Wheeler. 



Pheidole tisiphone sp. nov. 



Soldier. Length 5.6 mm. 



Head large; from above subrectangular, longer than broad, a little broader in 

 front than behind, with nearly straight sides and very feebly excised posterior 

 broader and a short, shallow occipital groove; in profile truncated anteriorly, flat- 

 tened above in front and feebly convex below, with a narrow and very deep scrobe 

 on each side, running obliquely backward and downward just over the eye to the 

 outer border of the gula and ending abruptly at the middle of the head. The edges 

 of the scrobes are sharp and parallel, the upper edges passing anteriorly into the 

 frontal carinae which are very widely separated. Frontal area small, deeply im- 

 pressed, rounded behind. Frontal groove obsolete. Eyes small, about 1-6 the 

 distance from the anterior to the posterior border of the head. Clypeus short and 

 very convex, with a faint, median, longitudinal impression, and entire and deflected
