Etoblattina sp. Pl. LXXIV, fig. 9. 
Dorsal border concave near the base, arched convex farther 
out, apex rounded; inner border full; radius reaching almost 
to the tip, with four or five superior branches; media with 
inferior branches filling the apex; cubitus with six or seven 
closely placed simple branches; anal furrow nearly straight. 
This species conforms closely to the typical Htoblattina type of 
hind wing. and more nearly resembles the Coal Measure hind 
wings than do any of the other types described from the Per- 
mian. The anal area is incomplete, the inner part only being 
preserved. Length of wing, 10 mm.; width, 5 mm. 
Formation and locality: Wellington shales, Banner City. 
Type, No. 769, author’s collection. 
Etoblattina sp. Pl. LXXIV, fig. 7. 
A much larger species is indicated by the basal part of a 
single hind wing. The part preserved is 11 mm. long. The 
full length of the wing was probably not less than 13 to 14 
mm. The wing is strong and all of the veins deeply im- 
pressed. The subcosta lies at the top of a sharp fold. The 
veins are closely crowded at the base, the subcosta, radius and 
media lying very close together. The first anal vein gives off 
three branches, the first two of which are forked. It is possible 
that this hind wing belongs with the associated large tegmina 
of Ktoblattina permiana. 
Formation and locality: Wellington shales, Banner City.

Etoblattina sp. Pl. LXXIV, fig. 1. 
Hind wing of medium-sized cockroach; costa submarginal; 
subcosta with two or three branches; radius reaching to the 
rounded tip; first branch of the media originating early, twice 
forked, second branch with two inferior divisions; cubitus and 
branches lax, first cubital vein forked; vein occupying the 
anal furrow once forked; first anal vein giving off three 
branches, the first of which is twice forked; wing broad, apex 
obtuse, veins not closely crowded at the base. The cubitus of 
this species is unusually lax, and the medius is differently 
branched from any of the associated species. 
Formation and locality: Wellington shales, Banner City.
