Etoblattina? sp. Pl. LXXIV, fig. 3. 
The species most common in the Permian is referred with 
some doubt to H'toblattina. There are no less than six recog- 
nizable specimens of this species. The costal border is less 
strongly arched than is that of the species last described. The 
subcosta is submarginal and short, reaching hardly to the 
middle of the wing. The radius is a strong vein. Its basal 
branch is given off early and gives rise to two or three branches 
beyond the subcosta. The third radial branch has also usually 
two or three branches. The media occupies a smaller area than 
does the radius. The cubital vein gives about four simple, 
curved veins. The anal furrow is well marked. The first anal 
vein gives off three branches, one of which is forked. A second 
anal furrow runs through the middle of the anal area, dividing 
it into two approximately equal parts. The branches from the 
first anal vein end on this furrow. Beyond the furrow the 
branches are once more longitudinal, and run parallel to the 
furrow. 
Formation and locality: Wellington shales, Banner City. 
- Etoblattina sp. 
Closely related to the wing last described is that of a speci- 
men having a similar fold with the veins of the anal area 
ending on the anal furrow, and with the veins beyond the 
furrow again parallel. It differs essentially in the more 
numerous branches of the first anal and especially in the pres- 
ence of reticulated cross-veins connecting these branches. The 
veins beyond the fold are more distinctly seen here than else- 
‘where. The first strong vein divides not far from the base. 
The inner of these divisions soon divides, and one of these 
secondary branches again subdivides. All run nearly parallel 
to the furrow, and all end on the inner border. This specimen 
is illustrated in Popular Science Monthly, March, 1906. 
Formation and locality: Wellington shales, Banner City. 
Puknoblattina compacta? 
The association of these wings with Puknoblattina is based 
on their agreement in size and the fact that no other small 
cockroach has been found present at the locality. The costal 
‘border of the wing is very slightly rounded. The subcostal 
area is narrow and extends to or somewhat beyond the middle 
of the wing. The radial vein is strong and sends three or 
four branches to the costal border. The media sends about
