TERTIARY FOSSIL WING FROM QUEENSLAND—TILLYARD. LY 
In Scolypopa Stil, all these have been eliminated 
with the exception of a complete set which forms 
a second or discal gradate series, and one or two 
more basally situated between M and Cu. 
(4) In Scolypopites n.g., Rs is strongly branched not far 
from its origin. In Scolypopa Stil, Rs. is either 
reduced to a simple vein, as in Text-fig. 2, or it 
does not branch until about midway along the 
wing. 
(5) The manner of branching of M and Cu, in Scolypopa 
is very variable. Text-fig. 2 is taken from a speci- 
men in which the branching of M. is trifurcate, as 
in the fossil. Many specimens, however, show the 
two veins M labelled M, and M, arising from a single 
stem which is itself a dichotomy with the vein 
marked M,+, ; it is for this reason that these 
veins are so named. I think, therefore, that the 
trifurcate forking of M in Scolypopites n.g. may be 
only an individual character of this particular 
wing, and so I do not propose to include it in the 
generic definition. For the same reason I omit 
mention of the particular form of branching of Cu, 
and its manner of connection with M,, since these 
also are highly variable in Scolypopa.

The fossil consists of the tegmen or forewing only, well 
preserved, but with the clavus or anal area entirely absent, 
as is very usually the case with fossil Homoptera, owing to the 
- deepness of the impression of the vena dividens (Cu,), which 
causes the wing membrane to split, so that the clavus usually 
drifts away from the rest of the wing and becomes fossilised 
by itself. Total length 15 mm. ; greatest breadth (measured from 
tornus to costa at right angles to the latter), 95 mm. The 
impression is on a dark ochreous-brown sandstone rock, rather
