 impressed : the metanotum short, the basal portion extremely 

 short, transverse ; the metanotal spines at the posterior lateral 

 angles proportionately rather long, curved inwards and slightly 

 downwards, the apical portion of metanotum concave. Pedicel 

 short and broad, the 1st joint flat above, semicircular anteriorly 

 and arched at the sides ; 2nd joint seen from above with a trans-

 $ . Ergatoid, wingless, the formation of the thorax being almost 

 identical with that in the ^ ; the mesonotum, however, is large and
