NOTOBLATTITES MITCHEI-M, n.sp. (Text-fig 9). 



Greatest length of fragment, 24 mm. This specimen, \vl>ich 

 shows a remarkably close resemblance to the type-species, N. 

 suhcostalis Tillyard, is a beautifully preserved fragment, showing 

 an area of the tegmen crossed by the distal half of the median 

 vein, with a small portion of the radial sectors above it, and a 

 considerable part of the cubital and first anal veins below it. 

 The forkings of these veins are very regular and narrow, and the 

 spaces between them are closely filled with a typical Palaeodicty- 

 opterous mesh work, which is very well preserved. A compari- 

 son with the figure of the type-species of this genus, shows how 

 closely similar this area of the tegmen is in the two species. 

 Nevertheless, as the second branch of the radial sector above M

in the new species is definitely forked, whereas, at this same 

 point in the type-species, there is only a simple longitudinal 

 vein, I have decided to place this specimen as a new species, 

 which I dedicate to its discoverer. 



In the Collection, there were two specimens, Nos 1 and 2, 

 which contained closely similar fragments of this insect. On 

 fitting these together, I discovered that they wtre part and 

 counterpart, respectively, of the same impression. As the two 

 specimens do not cover quite the same area of the wing, 1 made
