This species, originally described from a near-by locality in 
the Lawrence shales, is found to be represented in the present. 
collections. The type specimen seems to have been somewhat 
larger than is the average for the species. 
Formation and locality: Le Roy shales, Upper Coal Meas- 
ures, Lawrence, Kan.

A new species of cockroaches in the Le Roy shales is repre-- 
sented by one specimen and its counterpart. The slender teg- 
mina is unusually coriaceous, the veins, except those of the: 
anal area, being entirely obscured. The most marked char- 
acters are the extreme slenderness of the tegmina, its thick 
texture, the rounded prominent shoulder at the base, and the 
squarrose appearance of the anal area. The form is evidently 
specifically if not generically distinct from any heretofore de- 
scribed. Length of tegmina, 20 mm.; width 7 mm. 
Formation and locality: Upper Coal Measures, Lawrence, 
Kan. Type No. 115, University of Kansas collection. 
Etoblattina fulva sp. nov. Pl. LXX, figs. 4, 6, 9; pl. LX XIX, fig. 3; 
pl. LXXXI, figs. 3, 6. 
Medium-sized cockroaches with tegmina preserving as 
brownish colored impressions. Subcostal area reaching hardly 
beyond the middle of the wing. The main vein curved and. 
giving off arched simple branches. The radius falls a little 
short of the apex. The media branches before reaching the 
middle of the wing. Its branches are strong and longitudinal, 
forking at the tips. The cubitus reaches beyond the inner 
angle of the lower border. The anal furrow is well marked. 
The area is provided with eight to ten simple veins. 
Formation and locality: Le Roy shales, Upper Coal Meas- 
ures, Lawrence, Kan. Nos. 130, 142, 192 and 28, University 
of Kansas collection; Nos. 37 and 80, Yale collection. 
Etoblattina permiana sp. nov. 
Subcostal area broad, but short, hardly reaching beyond the 
middle of the wing; branches numerous, mostly simple, arched 
in passing from the main vein to the border. Radius and 
branches prominent. First and second superior: branches
