 decidedy more convex ; the epinotum is much less angular, 

 more rounded, and sloping ; the petiole in profile lower in front 

 and with a more evenly-rounded slope rising to the highest 

 jDoint at the posterior end of the segment ; the petiole, the

 decidedly longer than in adlerzi. 



S . — Length, 6 '5 mm. 



Head, including the eyes, broader than long ; eyes very

 through the wing insertions about as broad as the head 

 through the eyes ; mesonotum without Mayrian furrows, con- 

 vex, broadly elliptical, a little longer than broad, not concealing 

 the pronotum when seen from above. Epinotum rather long, 

 in profile sloping, the base about twice as long as the declivity. 

 Petiole similar to that of the worker, but proportionately 

 shorter. Gaster and legs slender. Head and thorax sub-

7. PoDOMYRMA bimaculata, Forel. 



Two workers from Flat Rock Hole in the Musgrave-
