as the strengthening vein by fusing with Rs at its very beginning. 
Except for this fusion of MA with Rs, Becquerelia is scarcely dis- 
tinct from Palaeoptilus , both in venation and in coloration. 
The known Commentry species of Becquerelia are superba Brong- 
niart and tincta Brongniart; elegans , as noted above, probably belongs 
in this genus,, but its fragmentary condition does not allow further 
description. 
Becquerelia superba Brongniart

Becquerelia superba Brongniart, 1893: 357, pi. 19, fig. 1; Handlirsch, 1906: 
105, pi. 11, fig. 22. 
This species is based upon specimen 19-1, consisting of a well 
preserved hind wing with a clearly preserved color pattern. 
Hind wing: length 85 mm, width 27 mm; broadest just beyond 
the base; anterior part of cuticular thickening running from the 
beginning of Cu obliquely to the bend of Ai ; posterior part of the 
thickening following Ai for some extent, then parallel to it until 
the bend in Ai ; several supporting cross veins are present between 
the base of MA and R + Rs; color markings forming numerous 
light elongate spots, arranged into about eight transverse bands; 
apical part of wing elongate, the apex rounded, directed posteriorly; 
anal area somewhat enlarged, with about 12 oblique cross veins in 
its distal half; Rs with six very oblique, simple branches; MA with 
about four long branches; MP forked about five times; CuA with a 
series of five long branches; CuP forked twice; anal area, with nine 
simple branches; cross veins less numerous in the anal area, where 
they form rows. 
Becquerelia superba (hind wing) differs from tincta (basal part 
of fore wing) in having the first fork of MP directed more poster- 
iorly, by the presence of long forks on the anal veins, and by the 
patches of additional small light spots near the base of the wing, 
although the latter might be an individual trait, rather than specific. 
Becquerelia tincta Brongniart

105, pi. 11, figs. 23-24. 
This species is based upon specimen 20-3, consisting of the proximal 
third of a fore wing. The color pattern is not distinct. 
Fore wing: length of fragment 24 mm, width 25 mm; light, elon- 
gate spots forming transverse bands; cuticular thickening apparently
