370 MESOZOIC INSECTS OF QUEENSLAND, vi., 



rest apparently end upon the posterior margin of the wing. 

 Second and third anal veins simple, the fourth forking about 

 midway, with an extra distal fork on the anterior branch. The 

 other anal veins not fully preserved, but some of them are 

 evidently forked. Distance between first and second anal veins 

 much greater than that between the others. 



Type, Specimen No. 180a, with its counterpart No. 1806 (the 

 latter shows only about the basal two-fifths of the tegmina). 

 (Coll. Queensland Geological Survey). 



Horizon: Upper Triassic, Ipswich, Q. 



Triassoblatta insignita, n.sp. (Text-fig. 32). 



A fragment of a single left tegmen, including almost the whole 

 of the anterior portion from base to apex, with humeral area, Sc 

 and most of R, also the bases of M and Cu, more than half of 

 the vena dividens, and the upper portion of the anal area. 



Greatest length, 19*5 mm., representing a total length for the 

 tegmen of about 21 mm. Greatest breadth of fragment, 4 mm., 

 representing an estimated total width of tegmen about 8 - 5mm.

Triassoblatta insignita, n.g. et sp. (x5'4). Fragment of left tegmen. 

 Upper Trias of Ipswich, Q. Drawn from Specimen No. 124. 



Humeral area 6 mm. long from base to apex, moderately wide, 

 and having its anterior or costal border strongly thickened; this 

 thickening extends as far as the third branch of Sc. First two 

 branches of Sc simple; distad from these follows a long sector 

 giving off four branches; beyond this is another forked sector, so 

 that the total number of branches sent by Sc to the wing-border 

 is eight. Radius apparently gives off six primary branches to 

 the anterior border, exclusive of the forked end of the main 

 stem. Of these, the first is a forked vein, the second simple, the
