This genus is undoubtedly close to Blattinopsis but differs from 
it by having ( i ) distinctly few cross veins over the wing in general 
and especially in the distal portion and (2) clearly defined grooves 
in the wing membrane between the branches of Rs and M. Sindon 
Sellards and Pursa Sellards seem to me to be inseparable from 
Glaphyrophlebia; as shown below, the type-species of both of these 
genera possess the venational characteristics of Handlirsch’s genus. 
Glaphyrophlebia is represented by one species ( clava Kukalova) from 
the Lower Permian of Moravia and two species ( uralehsis Martynov 
and rossicum Martynov) from the Permian of USSR, both orig- 
inally described in Sindon. 
Glaphyrophlebia speciosa (Sellards) 
Text-figure 8 
Sindon speciosa Sellards, 1909, Amer. Journ. Sci., 23:154, fig. 1. 
Fore wing: length, 8 mm., width, 3.8 mm. (neotype). Sc ter- 
minating at mid-wing; Ri strongly sigmoidal; Rs with seven main 
branches, each forked distally; M (in type, probably variable) forked 
only near wing margin; oblique part of CuA slightly basal to the 
origin of Rs; CuA with only about six branches leading to the hind 
margin; costal veinlets unbranched (in type), separated by spaces 
about equal to their length; cross veins in the area of the subcosta 
and Ri with similar spacing; veinlets from Ri to the costal margin 
beyond the end of Sc somewhat more numerous and closer together; 
cross veins in the area of Rs, M and CuA widely spaced ; no reticula- 
tion between CuA and CuP, although two rows of cells occur in 
that area basally; anal area without a reticulation. 
The holotype specimen, No. 85 in the Sellards collection, was 
studied by me in 1927, at Austin, Texas. Since this fossil has sub- 
sequently been lost, I designate as the neotype specimen No. 6303, in 
the Museum of Comparative Zoology. This was collected at Elmo, 
by F. M. Carpenter in 1927; it consists of a complete and well pre- 
served fore wing. Sellards figure of the original type was slightly 
in error in showing Sc too long and in showing too many branches 
from CuA to the wing margin. The neotype is very close to the 
original type except that in the latter the fork of M was much 
deeper. As pointed out by Kukalova (1965), the branching of M is 
subject to much fluctuation within the species of Blattinopsidae. 
The venationai details of this species are shown in text-figure 8. 
So far as I am aware, this is the only species of the Blattinopsidae 
known from a co?nplete wing.
