810 Handl'wsch — New Paleozoic Insects from the 



would be the case with Propteticus infernus Scudder, if the 

 drawing of the subcosta should prove to be wrong. The same 

 thing is true of GamptopJdebia clarinervis Melander and 

 Paracheliphlebia externa Melander, perhaps also of Miamia 

 bronsoni and Dieconeurites rigidus Scudder. All these forms 

 need careful reexamination. 



Dieconeura Scudder. 



Dieconeura mazona, new species. Fig. 15. 



Body conspicuously long and slender. The 3 segments of 

 the thorax nearly equal in length; prothorax narrow, about 



Fig. 15. 



Fig. 15. Dieconeura mazona. x 2 - 5. 



one and a half times as long as broad, 3 - 5 mm long. The head

 shorter from the first to the fourth, then increasing to the 

 eighth and ninth. Apex of abdomen extending beyond the 

 wings.
