Figure 44 
Peromaptera filholi Brongniart, 1883 : 393, pi. 22, fig. 15; Handlirsch, 
1906: 80, pi. 10, fig. 8; Lameere, 1917: 160. 
This species is monotypic, based by Brongniart upon specimen 
22-15, which was represented by a fore and a hind wing. For the 
drawing given here only the photograph was at my disposal. The 
base shows almost surely the stems of R and M touching as in 
Dictyoptilus. The precostal area being only fragmentary in the 
fossil is not so distinct. The hind wing venation unfortunately does 
not show convexities and concavities and has been interpreted ac- 
cording to Lameere (1917, p. 160). 
Fore wing: length about 60 mm,, width about 13 mm (according 
to Brongniart, 1893). Anterior margin unknown, posterior margin 
concave in the middle part of the wing. Subcostal area broad basally ; 
Rs with about 7 branches, first of them forked; MA approaching 
the stem of Rs but not touching it; MP with two short branches; 
CuA independent from the stem of M but approaching it to some 
extent. Six anal veins. 
Hind wing: length about 40 mm, width about 16 mm. Anterior 
margin straight; apical part shortened, apex obtusely rounded, located 
at about the wing axis. Rs very long, with short single branch ; 
MP with a short fork at the end. Cu dividing proximally from M, 
occupying a narrow area. Anal veins far distant from each other, 
probably pectinate. Cross venation in hind wing with irregular 
thickening in the apical part. 
The fore wing of Peromaptera filholi differs from that of all 
other species of Eugereonidae in the much less developed MP. The 
branch of CuA is probably an individual variation only, formed by 
the thickened reticulation which is frequently noted in the related 
family Dictyoneuridae. Also, CuA is simple in the hind wing. Tbe 
shape of shortened hind wing recalls that of V aldeania medeirosi 
Teixeira, 1941 but the venation is completely different from that 
of the fore wing.

Type genus: Archaemegaptilus Meunier, 1908 
This family, being based on a wing fragment, was erected by 
Handlirsch with some uncertainty as to its affinities. Lameere (1918,
