Hana lineata, n.sp. 
Figures 6b and 7 
This species is based upon the proximal half of the longest and 
narrowest wing known in the Megasecoptera (see reconstruction, 
fig. 6b). The subcostal area is proximally partially superimposed 
across R. In figure 7 the venation is shown restored to its normal 
position. 
Wing: length about 96 mm, width 8.3 mm. Posterior margin 
convexly bent at the end of all branches of CuP ; Rs originating 
beyond mid-wing; first branch of MP long, starting before mid- 
wing; CuP with a series of 3 short branches; archedictyon and cross 
veins similar to those of filia, but finer. Wing membrane densely 
covered with small tubercles. A few dark spots occur in the sub- 
costal area. 
This species differs from filia in its narrower wings, finer mem- 
brane and its series of 3 CuP branches. 
Holotype: no. 28/1974 (wing fragment, length 58 mm, width 
8.3 mm; reverse). Paleontological Institute of Charles University, 
Prague.

Family Arcioneuridae, riew family 
Nymphal wing: petiolate, narrow, broadened at about mid-wing; 
posterior margin undulated. No coalescing veins; Sc short; Rs di- 
verging from R 1 well before mid-wing; MA and MP with several 
branches; CuA and CuP with few short branches. Cross veins 
numerous, forming intercalated sectors.
