Mexico is very similar, so far as can be seen in the type specimen, 
to that of Permobiella. There is one other genus of the Caloneuro- 
dea which has the short subcosta, this being A nojnalo gramma from 
the Lower Permian of Kansas. However, Rs in this insect has only 
two very short branches and the anal veins are quite differently 
formed. 
Genus Pseudobiella, new genus 
This includes species similar to those of Permobiella but with 
the cross veins normal or relatively weak, instead of very strongly 
convex, as in Permobiella. Both fore and hind wings are marked 
by several strongly contrasting transverse stripes, unlike those of 
Permobiella, which are without markings of any kind. Since the 
basal portion of the wing of Permobiella is unknown, it might be 
noted here that four anal veins are distinctly preserved in the hind 
wing of Pseudobiella fasciata; three anal veins are preserved in the 
fore wing, which, however, lacks the more basal region.

Fore wing: length, as preserved, 11 mm (estimated complete 
length, 1 1.5 mm); width, 2.5 mm. Hind wing: length, as pre- 
served, 10 mm (estimated complete length, 11 mm); width, 2.5 
mm. 
Holotype: No. 170366, U. S. National Museum; collected by 
Dr. Sergius Mamay in May, 1969, at an exposure of the Madera 
Formation in the Manzano Mountains, southeast of Albuquerque, 
New Mexico. 
As can be seen from the photograph (Figure 5), this specimen 
consists of all four wings and parts of the body (the head, antennae 
and thorax) ; the abdomen is completely missing. The venation is 
clear where it is preserved at all and the nature of its preservation 
is very unusual. The veins are distinct in those portions of the 
wings that were originally heavily pigmented but they are completely 
absent from the parts of the wings that were presumably hyaline or 
unpigmented. The symmetry of hyaline areas of all the wings shows 
that this is not just an apparent distribution of pigment but that 
it reflects the original color pattern of the wing. The left fore wing, 
as preserved in the fossil, extends to one side but the other three 
wings are aligned more or less in an overlapping position over the 
abdomen. Since these wings rest at slightly different angles, I was
