Carpenter — Caloneurodea 
I5i 
(1925) was in error in describing a large precostal area in this fossil ; 
he apparently did not realize that more than two wings were over- 
lapped, resulting in a confused jumble of veins. 
Apsidoneuridae, new family 
Fore and hind wings similar. Sc extending to about the apex of 
the wing; CuA and CuP very close together and nearly parallel; MP 
forked broadly and unevenly, the anterior branch (MP 1+2) arch- 
ing strongly away from MP 3 + 4; 3 anal veins; cross-veins numerous. 
Body unknown. 
This family is related to the Caloneuridae but differs in the length 
of Sc, the number of anal veins and the nature of the fork on MP. 
It is based on the type-genus Apsidoneura Carpenter (Permian, Kan- 
sas), which was originally placed in the Permian family Paleuthy- 
grammatidae. Study of additional specimens of Caloneurodea from 
Permian strata of Oklahoma and of the type of similis from Commen- 
try has led me to conclude that Apsidoneura and Homaloptila represent 
a distinct family. 
Genus Homaloptila Handlirsch 
Homaloptila Handlirsch, 1919, Denkschr. Acad. Wiss., 96:36. 
Rs with four main branches, one of these usually having a terminal 
fork; MP 3 + 4 continuing in a nearly straight line the stem MP, 
which arises from CuA at a considerable distance from the separation 
of CuA from R. In Apsidoneura , MP arises from R or the junction 
of R and CuA. 
Type-species: Homaloneura similis Meunier. This is the only 
species known in the genus.

Fore wing: length, 30 mm., maximum width, 7 mm. Rs with four 
main branches, at least two of which are forked distally. MP 1+2 
arched away from MP 3 + 4 as characteristic of the family, but 
curved strongly towards MP 3 + 4 distally. There is a tendency for 
the formation of an irregular network of cells in the distal parts of Rs 
and MP. Base of wing slender but not as slender as in Apsidoneura 
flexa. Hind wing: similar to the fore wing in size and venation but 
having a straight costal margin towards the base. The venational 
pattern is shown in figure 2.
