classification of the Breyeriidae has been reviewed by Kukalova 
(1959); there now seem to be only two valid genera, Breyeria 
Borre and Strobbsia Handlirsch. The latter is known from the 
Upper Carboniferous of England but Breyeria is represented in 
the other European deposits mentioned under the family and is the 
genus to which the North American species belongs. 
Genus Breyeria Borre 
Breyeria Borre, C. R. Soc. Ent. Belg., 1875: 7; synonyms: Borrea Brongniart, 
1893; Megaptiloides Handlirsch, 1906; Pseudoborrea Handlirsch, 1919; 
Breyeriopsis Laurentiaux, 1949. 
Breyeria rappi, new species 
Plate 8 ; text-figure 1 
Fore wing: length 81 mm.; width 25 mm. Costal margin smooth- 
ly curved; costal space with a short longitudinal vein basally; costal 
space not broadened basally; Sc terminating on Ri just beyond the 
first fork of Rs; Ri extending to the very apex of the wing; R 
arising at the level of the fork of M, with six terminal branches; 
MP with three terminal branches; cross veins mostly straight, a 
very few branched in the area between Rs and MA; small circular, 
cuticular thickenings occur between some of the branches of Rs, be- 
tween Rs and MA, and between MA and MP. 
Etolotype: No. 158550, U.S.N.M., Washington, D.C.; collected 
by Mr. Robert Rapp in the “Pewee” Coal Seam at a strip mine 
near Peach Tree Gap, Anderson Country, Tennessee. The speci- 
men (Plate 8) consists of a virtually complete wing, lacking only a 
few millimeters of the apex, and it is perfectly preserved. The 
species is named for Mr. Rapp. Dr. Mamay has informed me ( pers . 
com.) that, on the basis of the fossil plants which Mr. Rapp col- 
lected in the Pewee Coal Seam, he considers the deposit to be of 
Lower or Middle Allegheny age. This would correspond closely to 
the Westphalian C Stage of the European Upper Carboniferous. 
This species differs from others in Breyeria by a series of minor 
(but presumably specific) characters, such as the general shape of 
the wing, the number and arrangement of branches of Rs and the 
pattern of cross veins. The fossil shows no sign of color markings, 
The fossil which Keller (1935) described as Breyeria constantini from 
the Upper Carboniferous of the Ruhr Valley in Germany is so fragmentary 
that its assignment to any family is problematical.
