Handlirsch to the genus do not exist; Sc, for example, was described 
as extending to the wing apex, but it actually terminates just beyond 
mid-wing, as in Diaphanoptera.

This species was based on a single, well-preserved wing, 38 mm. 
long and 1 1 mm. wide ; on the basis of the shape, I assume it is a hind 
wing. Its venation is shown in plate 32, fig. A, which is drawn directly 
from the type specimen in the Laboratoire de Paleontologie. All main 
veins are clearly preserved and their convexities or concavities distinct. 
Brongniart’s figure of the wing, although very small, correctly repre- 
sents the venation except in two areas : ( 1 ) The proximal parts of Sc 
and Ri are distinctly bent, as in other primitive Diaphanopterodea; 
and the stems of R and M are independent, not in contact, as suggested 
in Brongniart’s drawing. (2) MA, distinctly convex, arises from M 
at about the level of origin of Rs and then diverges abruptly towards 
Rs. These two veins do not, however, quite coalesce, as is shown in 
Brongniart’s figure; there is, in fact, a narrow space between them, 
even at the point of closest association. Handlirsch’s figure of C. 
munieri (1906), crudely copied from Brongniart’s work, shows the 
basal piece of MA as very weak and nearly transverse. This illustra- 
tion, which is definitely incorrect, has been reproduced in various publi- 
cations on wing venation and fossil insects (e.g., Comstock, 1918; 
Rohdendorf, 1962). Forbes’ figure (1943), although based on Brong- 
niart’s, is somewhat altered, depicting a broader, more oval wing, and 
representing the base of MA by a broken line. Actually, the basal 
origin of MA and its divergence to and away from Rs are clearly 
preserved in the fossil. 
Like the other diaphanopterids, munieri shows several large spots 
on the wing. Brongniart indicated six of these in his figure and I find 
this number in the fossil ; but I believe he included one which is actu-
