nier)] show similar patterns. The maculations on the wings of 
suzannaeci are much smaller and are arranged in definite rows, as 
shown in the photograph, Plate 9. 
The only palaeodictyopteron described from the ironstone nodules 
of Illinois that resembles N. suzanneae is Diexodes debilis Hand- 
lirsch (1911), which was based on a small, poorly preserved wing 
fragment. However, the cross veins in debilis (the type of which 
I have examined at the Peabody Museum) are relatively few in 
number and do not ? therefore, form the dense pattern characteristic 
of the Fouqueidae. 
Order Megasecoptera 
Family Brodiidae Handlirsch, 1906 
This family was established by Handlirsch for a single species, 
Brodia priscotincta Scudder from Upper Carboniferous deposits in 
England. From the time of its description in 1881, this species has 
presented numerous problems with respect to both the nature of the 
structures preserved and their phylogenetic interpretation. Although 
numerous specimens (at least 15) have been subsequently found, 
these have consisted only of isolated wings or fragments of wings; 
nothing is known, therefore, of the differences between the fore 
and hind wings or of the body structure. The relationships of Brodia 
have been uncertain. Handlirsch placed the family at first in the
