MESOZOIC INSECTS OF QUEENSLAND, VI., 



connect up with an}^ other vein. The fourth and fifth anals are 

 unbranched and nearly straight; the sixth a weaker vein, slightly 

 curved, and with a short distal fork. The seventh is a weak 

 vein, brandling into two not far from its base; each branch forks 

 again near its distal end. The fused distal ends of the second 

 and third anal veins appear to end up almost exactly upon the 

 apex of the area; all the veins below these end upon the pos- 

 terior margin (pm). Traces of a true archedictyon are evident 

 in this fossil, hut have been omitted from the drawing in 

 Text-fig. 33.

TriassohlattaC.) intermedia, n.sp. ( x 11). Left teamen, anal area. Upper 

 Trias of Ipswich, Q. Drawn from Specimen No. 216.

 Survey). 



Horizon: Upper Trias, Ipswich, Q. 



The anal area described above is intermediate in size between 

 those of T. typica, n.sp., and /'. insiynila, n.sp., and probably 

 belonged to a tegmen about lb' mm. in length. In showing 

 traces of an archedictyon, it comes closest to the anal area of T. 

 insignita. The arrangement and branching of the anal veins is 

 very distinct, and should alone enable us to recognise the species 

 again, if by any chance a more completely preserved specimen be 

 one day found.
