MESOZOIC INSECTS OF QUEENSLAND, V., 



AlUSTOPSYCHE SUPERBA, II. Sp. (Tex t-fig.25). 



Greatest length of fossil, 24 ram. (representing a complete wing 

 about 25 mm. long, with a small piece of the extreme base miss- 

 ing); greatest breadth, 8'2mm. 



This fossil is perfectly preserved, except for a small portion of 

 the base and anal area; the wing had evidently been torn trans' 

 versely across the anal veins before becoming fossilised, so that 

 these veins are all slightly displaced basally. A weak, irregular 

 curved line below the basal portion of Cuj appears to represent 

 the crinkle in the wing-membrane due to this displacement The 

 first vein lying below this crinkle should be Cu„, the second 1A, 

 and the third 2A, 3 A being apparently obliterated owing to the 

 poor state of preservation of the wing near the base anally. It 

 might be maintained, however, that these three veins were the 

 three anals, Cu 2 being represented either by one of the two 

 oblique descending branches from Cuj, or possibly even by the 

 weak, curved line which I have preferred to interpret as a crinkle 

 in the membrane.

 0, distal end of short costal vein; rest of lettering as usual in Com-

Cross-veins present are :— two between the costal border and 

 the short separate vein C; five between the costal border and 

 Sc, of which the most basal is bent backwards towards the tip of
