obtuse. Costal area only slightly broadened; Rs originating well 
before the middle of the wing, with four branches. Anal area small, 
with five branches. Hind wing length 64 mm, width 18 mm. There 
are minor venational peculiarities in the wings of this fossil but 
these are almost certainly individual traits and not specific ones. 
For example the level of the division of M is anterior to the origin 
of Rs in the fore wing but it is posterior to the origin of Rs in the 
hind wing. 
Body structures: length of head 5 mm, width about 9 mm. 
Antennae composed of many short segments. The length of the 
beak, incompletely preserved, 8.6 mm. The palpi orginate beneath 
the stylets, probably under the inner pair; segments of palpi with 
longitudinal, rugose ridges; first segment length .8 mm, Tnd 3.9 
mm and 3rd 2.3 mm.

This species was based by Meunier on an isolated, incomplete 
fore wing with a well preserved archedictyon that forms numerous 
twigs. In the collections of the Institut in Paris I found another 
fore wing, completely preserved, which I am referring to the same 
species. 
Comparing the type specimen of agnita with the type of fayoli 
(originally referred by Meunier to S. gaudryi Brongniart), I was 
unable to find any significant differences. Both the specimens are 
very similar in venation, in the details of the form of the posterior 
margin, in the nature of the archedictyon and the general shape of 
its cells. I am therefore synonymizing fayoli with agnita. 
The following account is based on all three specimens of agnita . 
Fore wing: length 70-74 mm, width 15.5-18 mm. Anterior 
margin convexly curved proximally, then almost straight. Posterior 
margin with two concavities between iA and CuP and at the end 
of CuA. Apical part of wing gradually narrowing. R-rs area broad ; 
Rs originating before mid-wing, with 4-6 branches; MP simple or 
with an additional branch. Anal area with six veins. Archedictyon 
dense, strong, forming extra twigs. Many anastomoses between 
cross veins.
