f E remains unbranched until well beyond half-way along the wing. 



Mesoscytina, n.o-. 



E branches into two slightly before the level of the branching 



of M. Mesodiphthera, n.g. 



E unbranched ; the series of veinlets between it and the costa ex- 

 tending from base to apex. Tjriassoscarta, n.g. 



E branched just before half-way ; the veinlets between it and the 

 costa beginning just beyond the dichotomy of E, and continuing 

 to the apex, with a series of cross- veins beneath them, between 



the two branches of E. Permoscarta Till. 



(Upper Permian of Newcastle, N.S.W.) 



I First dichotomy of E placed closer to the origin of E from~M than 

 to the second dichotomy of E ; only two veinlets from the most 

 anterior branch of E to the costa. Mesocixius, n.g. 



First dichotomy of E much closer to second dichotomy than to 

 the origin of E ; a series of parallel veinlets from the most an- 

 terior branch of E to the costa: Trjassocixius, n.g. 



Subfamily SCYTINOPTEEINAE. 

 Genus Chiliocycla, n.g. (Text-fig. 2) . 



Basal two-thirds or more of the tegmen covered with a re^ 

 markably strong sculpture of small, flat, circular tubercles set 

 closely together. R with a single posterior branch arising a 

 little before half-way; this branch connected to M 1+2 by a 

 single cross-vein above the median cell. M branches dichotom- 

 ously at a level only slightly nearer to the base than the apical 

 end of the clavus; the lower branch of M again divides, and the 

 median cell is closed by a cross-vein from M 1+2 to M 3 . Cii]
