The green casque could refer also to the 'scarab' in these lines from Canto
74:

    the great scarab is bowed at the altar
    the green light gleams in his shell


The katydid's another candidate:


   being given a new green katydid of a Sunday
   emerald, paler than emerald
                  minus its right propeller

Here we find also the intersection of 'war' with 'green world', in 'its
right propeller'.
