aid in working out venational details. I am also grateful to Dr. 
Jarmila Kukalova, of Charles University in Prague, who studied 
these fossils with me during her visit to Harvard University in 1964 
and who prepared several of the drawings which are included in the 
present paper. 
Order Miomoptera martynov 
This is an order of small insects, apparently related to the Pro- 
torthoptera. The fore wings were membranous and the hind wings, 
which lacked an expanded anal area, had the media arising from the 
cubitus and had CuA and CuP anastomosed for their entire lengths, 
forming a strong concave vein. The order is known from Upper 
Carboniferous and Permian strata. 
Family Metropatoridae Handlirsch 
Metropatoridae Handlirsch, 1906, Proc. U.S.N.M., 29: 681 
Metropatridae Martynova, 1962, Osnovy Paleont. :286 1 
Related to the Archaemiopteridae and Palaeomanteidae. Hind 
wing nearly oval ; Sc short, weakly developed and close to R, as in 
Palaeomanteidae; Rs forking before mid-wing, forming 6 terminal 
branches; MA arising independently of CuA at the base of the wing 
and forked almost to the level of origin of Rs; CuA + CuP with 
short terminal fork. Fore wing and body unknown. 
Genus Metropator Handlirsch 
Handlirsch, 1906, Proc. U.S.N.M., 29: 682 
Hind wing: R4+5 more deeply forked than R2 + 3 ; R3 with a 
deep fork, R2 with a very shallow one; Mi +2 forked distally, 
M3 + 4 forked twice. Type-species: Metropator pusillus Hand- 
lirsch 
The generic name Metropator is obviously derived from the identical 
Greek word for “maternal grandfather”. The genitive of this is Metropa- 
toros , providing the root Metropator- and, therefore, the family name 
Metropatoridae. 
In changing the name to Metropatridae, Dr. Martynova was apparently 
misled by the normal Greek word for father (pater), which ordinarily has 
the stem patr- ; pater, however, as used in the compound metropator, does 
not follow pater in declension, although it means the same thing and is 
merely a collateral form of that word. Since Handlirsch used the generic 
name Metropator, there is no question about the root or the spelling of the 
family name. I am indebted to Mr. Charles C. Porter for providing me 
with this etymological information.
