Thus, there cannot be any doubt about the fact that, in the hind 
wings of the Manteodea, the vein which is situated behind R is Rs y 
which is characteristic also for the hind wings of the Paleozoic and 
Mesozoic Blattodea. 
In the hind wings of the Manteodea a free base of MP, which 
Smart (1956) designates as the “oblique cross-vein”, is preserved. 
Among the Polyneoptera a similar vein is preserved in the hind wings 
(After Smart, 1956, with changed designations of the veins.) 
of Plecoptera and Orthoptera. Its homology with the same vein 
in the fore wings, in the cases where it is preserved, seems obvious.
