Family Archipanorpid.e, fam.nov. 



Characters as for the Order, with the following additions 

 Large insects, with a wing-expanse of 100 mm. or over. Ptero- 

 stigma longer and narrower in hind wing than in forewing, not 

 reaching proximally to Sc in either wing. 8c ends up on the 

 anterior margin of the M'ing beyond half-way in both wings, but 

 not so far in hindwing as in forewing. Cu^ ends up on posterior 

 margin a little before the level of the pterostigma in forewing, 

 considerably before the same level in hindwing. C'Uo probably 

 present in botli wings. 



Genus Archipanorpa, n.g. 

 (Plate viii., figs. 4-6; Plate ix.) 



Characters as for the family, with the following additions. 

 Forewing broadest at or near pterostigma, hindwing broadest 

 just before half-way, and having the apical third distinctly nar- 

 rower than in forewing. Pterostigma of forewing rather short, 

 irregularly shaped, with R arching up within it, convexly to the 

 wing-border. Pterostigma of hindwing long and narrow, with R 

 running almost straight through it. 



Genotype, Archipanorpa magnijica, n sp. 



Archipanorpa magnifica, n.sp. (Plate viii., figs. 4-6: Plate ix.) 

 This species is represented by two fine fossil wings, Nos. 

 106rt and 120a, in the Queensland Geological Survey's Collec- 

 tion. Of these, No.l06<( is the better preserved specimen. It 

 shows the whole of the wing from the apex to a level slightly 

 distad from the origin of Rs. A transverse fracture of the 

 rock has destroyed the base. The total length of this fragment 

 is 33 mm., its greatest breadth 13 nim. The specimen represents 

 a cant of a left hindwing. 



No. 120a is not so well preserved, there being two pieces cut 

 out from the posterior margin, and two slight cracks running 

 across the wing. The main fracture, which appears to be the 

 same break that cutoff the base of No. 106a, (the two wings were 

 found very close together) has cut off this wing more obliquely, 

 and a little further from the base (see Plate viii., figs. 4-5). The
