art, 1893; Lithoptilus Lameere, 1917. No other genera are known 
except for an undescribed specimen of Megaptilus in the Museum 
of Comparative Zoology from the Westphalian of Rhode Island. 
Megaptilus Brongniart 
Megaptilus Brongniart, 1885: 61; Brongniart, 1893: 373; Handlirsch, 1906: 
80; Lameere, 1917: 156. 
Type species: Megaptilus blanchardi Brongniart, 1885 (SD 
Handlirsch, 1 906 ) . 
This genus was established by Brongniart for three species, 
Megaptilus blanchardi, brodiei and scudderi. Handlirsch (1906, 
p. 98) referred brodiei to a new genus, Megaptiloides , and placed 
it in the family Breyeriidae; he referred scudderi (1906, p. 118) 
to another new genus, Paramegaptilus , and transferred it to the 
Palaeodictyoptera incertae familiae; and he erected a new family, 
Megaptilidae, for blanchardi. 
The following account is based on the type species (fore wing) 
and a hind wing of Megaptilus species (Westphalian of Rhode 
Island) . 
Wing membrane usually dark, sometimes with light oval spots 
arranged in longitudinal rows. Fore wings broad and short, broadest 
at about the middle. Sc long, remote from C in the apical third; 
first branch of Rs originating before the middle of the wing, forked 
several times; m area much larger than cu area. Anal area rela- 
tively small, with several branches. Hind wing with obtuse apical 
part and with very narrowed rs and mp areas. Cross venation 
equally dense in both wings. 
Megaptilus (hind wing) differs from Lithoptilus Lameere (hind 
wing) by Sc, R, and stem of Rs being parallel and curved, with the 
more dense cross venation with more anastomoses.

This species was erected by Brongniart upon specimen 21-3, a 
large fore wing fragment. Using glycerin, I was able to work out
