NO. 1441. AMERICAN PALEOZOIC INSECTS— HANDLIRSCH. 803 



Through various manipulations the original is somewhat disfigured, 

 and in consequence seems actually like a hemipteran wing, while th<' 

 counterpart makes a quite dili'erent impression. In all prol)a))ility it 

 may belong to a Protorthopteron or to a similar t'oi'in.

This gigantic insect has been placed ])y authors in most heteroge 

 neous groups, but in my opinion it will only be rightly interpreted 

 when an entire example, with the l)ase and the posterior margin of 

 the wing, is at hand.
