Other larv£e of Tctraponera {natalcnsis, allaborans, etc.) are not

 frons. Four distinct stages, probably separated by moults, or ec-

 The head is surrounded by a cluster of prominent, tubercle-like ap- 

 pendages. On the prothorax, which is large and forms a great hood 

 over the head, there are three pairs of these appendages, an anterior
