sent in the maxima but well-developed in the female, is dis- 
tinct in specimens (b), (e), (g) and (i) and faintly indi- 
cated in some of the others. There is a distinct though 
small metanotal sclerite like that of the maxima (absent in 
the minima), and the foveolse on the pronotum are also 
stronger and more numerous as in that caste. In two of the

larger and broader than in the normal maxima and there- 
fore more as in the female. In (g) even the scutellum of 
the latter seems to be indicated by faint lateral impressions 
but not by a suture marking it off from the mesonotal 
scutum. The petiole of all the mermithergates is like that
