the enigmatic Dictyocicada antiqua, from the Commentry shales; an 
account of this specimen will be included in another article dealing 
with Dictyocicada and related genera. 
Order Protodonata 
Very few specimens of this order have been found in the Upper 
Carboniferous deposits of North America. Up to the present, only 
five species have been described and all are known by single 
specimens. These are as follows: 
(1) Paralogus aeschnoides Scudder, 1893, Family Paralogidae, 
from East Providence, Rhode Island (Allegheny Series, comparable 
to the Upper Westphalian of Europe). (2) Palaeotherates pennsyl- 
vanicus Handlirsch, 1906, incertae familiae, from coal beds near 
Pittsburgh, Pennsylvania (Upper Pottsville, comparable to the 
Middle Westphalian of Europe). (3) Paralogopsis longipes Hand¬ 
lirsch, 1911, incertae familiae, from near Mazon Creek, Illinois 
(Carbondale Formation, comparable to Upper Westphalian of 
Europe). (4) Typus durhami Carpenter, 1960, Family Meganeuri- 
dae, from coal beds in Durham, Georgia (Lower Pottsville, com¬ 
parable to Lower Westphalian of Europe). (5) Oligotypus makow- 
skii Carpenter & Richardson, 1971, Family Paralogidae, from Pit 
11, near Braidwood, Illinois (Carbondale Formation, comparable 
to the Upper Westphalian of Europe). 
We are now able to add a sixth specimen, collected in Schuykil 
Co., Pennsylvania, and contained in the Klose collection. Although 
a fragment, consisting of the basal part of a fore wing, the fossil is 
worthy of a formal description and a specific name. I have assigned 
the species to the genus Palaeotherates, the family position of which 
has been very problematical. Since the new species does not provide 
sufficient additional information to enable a family diagnosis, I still 
consider the genus incertae familiae. 
Palaeotherates Handlirsch, 1906 
The type-species, pennsylvanicus, is known from a distal frag¬ 
ment of a wing with typical protodonate features. Since the new 
species, described below, is based on a basal fragment of a wing, 
there is no way of knowing how closely these two species may be 
related. I have placed the new species here in order to avoid the 
naming of another genus at this time.
