284 MESOZOIC INSECTS OF QUEENSLAND, viii., 



an inadvertence, the Text-figures ol' Part 7 were not so numbered. P'orty should 

 be added to the number of each Text-fig. in Part 7, so that the last one is 64, not 

 24. Thus this Part begins with No. 65. In the same way, the figure on the Plate 

 accompanying Part 4 should be number 15, and the two figures on the Plate 

 issued with the Queensland Geological Survey reprints of Part 5 shoula be Nos. 

 16 and 17.
