Atustrdblattvla ip&viciensis, n.g. et sp. (x7i). Left tegmen. Upper Trias 



of Ipswich, Q. Drawn from Specimen No. lOoa. 



Humeral area of moderate width, without veins or markings 

 of any kind. 8c a straight, simple vein, bounding the humeral 

 areadistally. Main stem of R giving off eight primary branches, 

 exclusive of its apical continuation; of these the first two are 

 simple veins, the third forked near its base, the fourth simple, 

 the fifth forked, the sixth three-branched, the seventh and eighth 

 simple (as far as preserved). Sc, R and its branches are formed 

 of strong, thick veins, as in Samaroblatta blabe/lo'ides, n.sp.; M 

 and Cu are only moderately strong veins, each of which gives off 

 seven branches to the wing-border. Vena dividens very strongly 

 arched; the first anal vein complete, simple, ending on the pos- 

 terior border just below the apex of the area; the other anal 

 veins only partially indicated towards their bases and apices.
