small piece cut out from the apex of the wing above the upper 

 branch of lis, and slight breaking away of the border distally 

 beyond the end of lA, and also basal ly on the clavus. 



The specimen lies on the smooth, ochi'eous-grey surface of a 

 very hard rock, and is of a somewhat darker colour (ochreous- 

 brown) than the rock-surface. It also carries black, carbonised 

 patches, which are quite absent from the rock itself, and may 

 possibly be due to the carbonisation of an original wing-pigment. 

 These markings take the form of a black band along the cori- 

 aceous border, with irregular patches extending in as far as Rj, 

 a very definite mottling of black specks, inclined to run together, 

 on the distal half of the corium, and a similar but less distinct 

 mottling on the broad basal half of the clavus. 



Type, Specimen No.23 in ColL Mitchell. 



Locality : — Taken from the top of the Dirty Seam, New- 

 castle, iN.S.W., near the Soldiers' Baths, at a level about two 

 feet above present high water-mark. The depth of this horizon 

 below the top of the Permian Coal-Measures is, as has been 

 already indicated, at least 850 feet.

Older HEMIPTERA. 



Suborder Hom.ptera. 



Family PEttMOFULCJOKID^, fam.nov. 



Medium-sized insects, with rather narrow, elongated tegmen, 

 in which certain cross-veins join obliquely with the main veins, 

 so as to simulate dichotomous branchings of the latter, and thus 

 form a series of apical cells, after the manner of recent Cicadidce. 

 Claval area with unspecialised, anal veins; the typical Y-vein of 

 recent Fuhjoridce not formed. Coriaceous border of posterior 

 margin of wing runs on distally beyond the end of the claval 



* This extraordinary character at once suggests {\\g snttirt of the Coleop- 

 terous ehtron. It is possible that we liave here tlie tirst formation oi that 

 structure; but the Honiopterous nature of this fossil seems fairly clear.
