recall those of some of the Spilapteridae but they have no other 
characteristics of that family. A separate family may eventually be 
needed for Madera ; for the present it seems advisable to place it in 
the family Lycocercidae rather than to add another family to the 
long list of those in the Palaeodictyoptera which are monospecific 
and based upon unique specimens. 
Madera mamayi, n. sp. 
Figures 1 and 2 
Fore wing: length, as preserved, 15 mm (estimated wing length 
15.5 mm) ; width of fore wing, 5.5 mm. Hind wing: length, 14 mm; 
width, as preserved, 5 mm. Fore and hind wings with six conspicuous 
transverse bands of dark pigmentation, as shown in the photograph, 
Figure 1. The venational details are included in Figure 2; the 
number of branches on Rs and MP differs slightly in the fore and 
hind wing but this is only consistent with what has previously been 
noted in other Palaeodictyoptera. 
The prothorax and fragments of some of the legs are preserved 
in this specimen but not well enough to allow me to make out details. 
The terminal portion of the abdomen is also preserved ; this clearly 
terminates in a pair of conspicuous cerci, which are bow-shaped
