Text-figure 4. Drawing of Parabattelytron subincisum Tillyard, based 
on specimen no. 5827, Mus. Comp. Zool. Lettering as in text-figure 1. 
The venation of the elytron of this specimen (text-figure 4) is 
typical of that of well preserved specimens of Parablatt elytron: the 
veins are about as long as in the Protelytridae but are very faint 
and fade out in their distal portions. The remigia of both hind 
wings are preserved but the anal fans are represented only by the 
more basal parts of the radiating anal veins. The subcosta of the 
hind wing terminates on Ri, instead of on the costal margin as in 
the hind wings of Protelytron and Apachelytron. Ri continues for 
a considerable distance beyond the end of Sc, finally terminating on 
the costal margin not far from the probable apex of the hind wing; 
weakly developed but distinct cross veins are present in the costal 
area along the length of Sc as well as along Ri beyond the end of 
Sc; Rs arises from R just before the termination of Sc and anasto- 
moses for a short distance with M ; thees two veins separate before 
terminating at the apex of the wing; M arises from the base of the 
wing as an indepedent vein and continues very close to R until near 
mid-wing (as in Apachelytron ) , when it forks into Mi and M2; 
Mi continues in a nearly straight line, diverging only slightly from
