SELLARDS. | Cockroaches. 533 
three longitudinal, simple or forked branches which reach the 
border at or below the apex. The cubital vein gives off four 
or five simple, nearly straight branches. Only a part of the 
anal area is preserved. That it presents the structure shown 
by other hind wings is, however, indicated by the small part 
preserved. The first anal vein is seen to give off two lateral 
branches. The parts of the wings preserved indicate a length 
of 814 to 9 mm.; breadth back of the anal area not less than 
4 mm. 
Formation and locality: Wellington shales, Banner City.

A very small hind wing, No. 472, represents a second but 
closely related species. The distribution of the vein areas is 
very similar to that of the species just described. The costa 
is submarginal and extends nearly half the length of the wing. 
The subcosta extends somewhat beyond the middle of the 
wing and gives off at least one branch. The radius, as in the 
last, reaches to the apex, having three superior branches, the 
first of which is forked. The median area is, as in the last 
species, well developed, having four superior branches, the sec- 
ond of which is forked. The origin of the main branch is ob- 
scure but is apparently fused for some distance with the radius. 
Cubitus has three branches. Anal area unknown. Length of 
wing, 6 mm.; width at the extremity of the median area, 2 mm. 
Formation and locality: Wellington shales, Banner City.
