The family name Kukalovidae Demoulin is consequently a syn¬ 
onym of Protereismatidae and the generic name Kukalova is a syn¬ 
onym of Protereisma. However, since there are adults of several 
species of Protereisma known in the Midco beds, and since there is 
no way of correlating the nymphs specifically with the adults, a 
different specific name is needed for the nymphs from the Midco 
beds. For this, of course, the name amerieana must be used. I can 
make no definite comment about the systematic position and 
nomenclature for the Moravian nymphs described by Kukalova and 
named by Demoulin. Examination of the original nymphs would be 
necessary to clear up the uncertainties of the venation. However, on 
the basis of Kukalova’s figure, I think it unlikely that the nymph 
which Demoulin named Kukalova moravica is a protereismatid. 
Figure 8. (above) Protereisma permianum Sellards. Diagram of venation of fore 
wing of neotype, MCZ 3405, Permian of Kansas. Convex veins are shown in heavy 
lines, concave veins in thin lines. Compare with figure 9. Lettering as in figure 2. Al, 
first anal vein; IR2, IR3, IMA, IMP, and ICUA, intercalary veins. 
Figure 9. (below) Protereisma americartum (Demoulin). Drawing of fore wing- 
pad, based mainly on MCZ 8637. Length of wing-pad, 5 mm. Compare with figures 8 
and 10. Lettering as in figure 8, but only convex veins labeled.
