PERMIAN AND TRIASSIC INSECTS FROM N.S.W. 



(?enus P E R MO FU L G o II, n.g. (Text-fig. 3). 

 Characters as for tlie family, witli the following additions. 

 Tegmen of delicate structure, not tuberculate, broadest not far 

 from the base: costal border slightly convex. Veins of the 

 clavus very strongly de\ eloped; those of the corium much weaker, 

 and not easy to make out. Veins 1 A and 2 A apparently both 

 two-branched from near their bases. Sc present, but ending up 

 on the costal border well before half way along the wing. K, M, 

 and Cu apparently all closely united near their bases. R leaves 

 M to run obliquely towards the costal border, and, at a level a 

 little before the end of Sc, divides into Rj and Rs, the latter 

 continuing the line of the main stem, while Rj arches upwards

towards Sc, then runs parallel to the wing-border for some dis- 

 tance, and finally meets it in an upward curve; about halfway 

 along Ri, a cross- vein connects it with Rs. M runs straight 

 below R, gradually approaching the costal border, but not reach- 

 in"- it. Cu diverges from M, becoming subparallel to lA; Cu 

 gives off an anterior branch Cuj a little beyond the level of the 

 origin of Rs; the main stem (Cu.,) is broken a little further on, 

 at a point where a long, oblique cross-vein connects it with lA, 

 and shortly afterwards divides into Cuoa and Cu.2b: At about 

 two-thirds of the wing-length, Rs, M, Cu^, and Cu2a are con- 

 nected by a set of three oblique cross veins, forming the bases of 

 three apical celh^ of which the two uppermost, at least, are again 

 divided by oblique cross-veins nearer to the apical border. [Hest 

 of tegmen missing].
