 the first segment of gaster has shallow punctures among the fine striae, 

 and the second segment has fewer and shallower ones. The anterior 

 border of the clypeus has a somewhat more pointed form, and the head 

 is not quite so emarginate behind as in typical forms.

addition to those already described might readily be named, but in all 



])robability many of these slight variations are found in the same colony, 



especially the colour variations. The metallic sheen ranges in all shades 



from red and purple to green and blue.
