Carboniferous of Pennsylvania, near Trenton. Length of wing fragment, 13 mm.

Caloneurodea, which were long and slender. It is conceivable that 
this fossil might be part of a nymphal wing of a protorthopteron or 
possibly of a caloneurodean. 
One specimen, No. 11030 (K6343) in the William Penn Memorial 
Museum, clearly belongs to the Protorthoptera. It was collected in a 
strip mine along strike, 500 meters west of Blue Coal Braker, 
Audenreid Village, Pennsylvania, and under clay of unnamed 
anthracite, 85 feet above Mammoth anthracite. It consists of the 
distal half of a fore wing, partially covered by plant fragments 
(figure 6). The venation is clear enough over the preserved part of 
the wing, which is 25 mm long, but since only Rl, RS, and part of M 
are preserved, naming the species seems pointless, especially since 
family determination is impossible. The fossil is of interest, how¬ 
ever, because it is only the second insect from the anthracite coal 
field of Pennsylvania that can reasonably be placed in the order 
Protorthoptera. The other species is Hapaloptera gracilis Hand- 
lirsch (see Carpenter, 1965). 
The Blattaria, as mentioned above, are by far the most numerous 
insects in the coal beds. Of the 45 roaches in the collections being 
studied, 21 are small fragments of fore or hind wings, and nothing 
can be done with them below the ordinal level. The remaining 24 
specimens fall into the families Archimylacridae and Mylacridae, 
there being 12 in each family.
