soft; the outlines of most of the veins are distinct, but the 
impression is slightly blurred here and there. Dotted portions 
of R, and Cu in Text-fig. 1 indicate restorations where the 
impression is not clearly visible. 
The principal specific characters are as follows :—The large 
size, the length and breadth being almost twice that of Scoly- 
popa australis, and very much larger than usual for the family. 
In the venation, the very strong basal arching of the costa, 
and its slight waviness beyond the end of Sc ; the less rounded 
apex compared with that of Scolypopa australis; the greater 
number and closeness of the costal and marginal veinlets, and 
the larger number of forkings of most of the principal branches 
of the main veins; also the weakness of the closure of the disc 
from the end of Se to the top of the marginal gradate series 
near the apex. 
The clavus has been restored, in Text-fig. 1, much on the 
lines of that of Scolypopa australis Stal. Weak irregular cross- 
veins, little more than mere impressions on the membrane, are 
generally present in the clavus of this species, and may well 
have been present also in the clavus of the fossil, but it has not 
been thought worth while to indicate such in Text-fig. 1. For 
a full comparison of the two types of venation, see Text-figs.

In conclusion, I wish to thank Mr. W. C. Davies, Curator 
of the Cawthron Institute, for the excellent photographic 
enlargement of the fossil wing from which the Plate has been 
prepared ; owing to the dark-brownish colour of the rock it 
proved by no means an easy task to photograph this specimen.
