branches arising from the wing base; Rs arising just before the end 
of Sc; CuA with several terminal branches; iA extending well 
beyond 2A and sending several short branches to the hind margin; 
cross veins usually straight, only rarely branched. Pterostigmal and 
apical areas of wing pigmented. 
Type-species: Promartynovia venicosta Tillyard. 
I have been unable to find sufficient differences between Pro- 
martynovia Tillyard and P er.melcana Sharov to justify generic sep- 
aration. Promartynovia was very incompletely known to Tillyard, 
who placed it in the order Neuroptera, and his description of P. 
venicosta was unsatisfactory, for the reasons given below. The type- 
species ( sojanense Sharov) of Permelcana Sharov is known by a 
nearly complete fore wing, which lacks only the apical region. Sharov 
had little reason to associate his fossil from the Upper Permian of 
the USSR with Promartynovia , although I had pointed out in 1943 
(p. 61) that the latter genus was orthopteroid not neuropteroid. I 
strongly suspect, also, that Proelcana Sharov, based on an apical frag- 
ment ( uralica Sharov) from Lower Permian deposits of Tchekarda, 
USSR, will turn out to be a synonym of Promartynovia; the amount 
of anastomosis between Rs and M, and the detailed arrangement of 
the branches of these veins, used by Sharov as generic characters, 
are highly variable within this group of orthopteroids.
