Affinities. — The sub-costal vein reaches the costal margin at 

 about 12 rnm. from the apex of the wing — a feature noted in 

 Fouquea. The radial sector originates nearer the base of the 

 wing than is shown in Handlirsch's figure. The actual junction is 

 not shown in Allen's figure. It must have been near the base of 

 the wing, much nearer the base than is seen in Fouquea. The 

 characters of the cubital and anal veins definitely remove the 

 species from Fouquea, as I have already noted ; indeed, the cha- 

 racter of the cubitus, with its strong anteriorly-directed twigs 

 and its feeble inner branches, is wholly unlike that of any other 

 insect, and would alone suffice to justify new generic rank. So 

 far I am in agreement with Handlirsch ; but I regard the 

 enlarged areas between the inner divisions of the radial sector 

 and the cubitus, and between the cubitus and the anal veins, as 

 more suggestive of the Proto-Orthoptera, notably Tlwronysis 

 ingbertensis Amnion. 



More than this cannot be said, and JPseudqfotiquea cambrensis 

 must be regarded provisionally as Palgeoclictyopteroid, with a 

 possibility of Proto-Orthopteroid affinities.
