 one-third times as long as its apical width; second and third tergites 

 of subequal length and of equal width, about twice as v^de as long; 

 the first tergite with a few poorly defined punctures; second and fol-

 vex, polished; propodeum shining with a few poorly defined punc- 

 tiu-es; areolations of the propodeum indicated by strong carinae;

 slightly curved carina; the basal lateral and median lateral areas not 

 differentiated; carinae of the first tergite extends a short distance
