422 MESOZOIC INSECTS OF QUEENSLAND, iu., 



While placing this fossil as more closely allied to Epiophfebia 

 than to any known Dragonfly, fossil or recent, it seems to me 

 that the characters exhibited by it require its elevation to sub- 

 family rank. But, if the area below the quadrilateral had pos- 

 sessed an anal bridge, I should have been content to place it in 

 the subfamily EpiojMehiiiuf. 



The Lestid affinities of the fossil appear to me to be beyond 

 doubt. As it appears that some students of the Odonata have 

 been unwilling to accept my removal of Epiophlehia to the family 

 Lesticke^ I should now like to draw their attention to this fossil, 

 which was unknown at the time that I made this suggestion. 

 The combination of Epiophlebiine characters from the quadri- 

 lateral distad, with the extreme reduction of the base, which 

 characterises this fossil, should surely be regarded as a further 

 link in the chain of evidence for the Lestid affinities of 

 Epiophlebia. 



Type, Specimen No. 205rt, (Coll. Queensland Geological 

 Survey). 



Horizon: Upper Triassic, Ipswich, Q. 



Odonata iNCEKTiE sedis. 

 Genus Perissophlebia, n.g. (Text-fig. 13). 



Between C and R, beyond pterostigma, an irregular double row 

 of cells. Between R and Mj, beyond level of pterostigma, at 

 first an irregular triple row of cells, followed by a more regular 

 double row. Below Mj, a strong convex sector is developed 

 towards the apex of the wing, three rows of cellules from it. 

 This is probably Mja- Close below this sector, and only a single 

 row of cells' width from it, there is a parallel concave sector. 

 Both the above sectors converge towards M^ as they approacli 

 the apex of the wing. Some three or four rows of cells below 

 the concave sector, there is a divei-ging convex sector, which is 

 probably Mo. 



[Only a fragment of the wing is preserved, embracing a por- 

 tion beyond the pterostigma]. 



Genotype, Perissophlebia midtiseriata, n.s^. (Upper Tri- 

 assic, Ipswich, Q.).
