Mesozoic insects of Quernsland, i.. 



The polygonal inesliwork of ridges is absent from all recent 

 Mecoptera. Microtrichia, however, are abundant all over the 

 wing-membrane, though excessively minute in some genera (e.g., 

 Fanorpodes). Macrotrichia are present only towards the distal 

 end of the wing, especially in the pterostigmatic region. In the 

 polygonal cells formed between Rs and Cuj, there may be seen, 

 in certain genera (e.g., Panorpa)^ two or three irregular rows of 

 macrotrichia. 



In the figures given in Plates viii.-ix., I have purposely 

 shaded-in the pterostigma, in order to distinguish it from the 

 rest of the wing-membrane. In the actual fossils, it is not 

 darkened in colour. 



Type, forewing. Specimen No. 120*^6; hind wing, Specimen 

 No. 1.06a (Coll Queensland Geol. .Survey).
