and with the costal space abruptly narrowed basally; hind wing 
narrower at base than the fore wing and with the costal margin nearly 
straight basally. Rs with five or six main branches, one of these 
usually having a short distal branch. MP usually forked, CuA and 
CuP unbranched. 
Type species: Caloneura dawsoni Brongniart. 
Confusio was based upon royeri, which Meunier described in the 
palaeodictyopterous genus Homaloneura, and which I consider a 
synonym of dawsoni.

This species was originally based on the single specimen figured in 
Brongniart’s 1885 paper but was later known to Brongniart by five 
additional fossils, all illustrated in his Recherches (1894). Five other 
specimens (here designated as C1-C5), which have not previously 
been mentioned in the literature, are contained in the Museum 
National d’Histoire Naturelle in Paris. To these may be added the 
specimen of dawsoni described by Bolton (1925), and the type of 
royeri Meunier. Since I am convinced for reasons given below that 
these thirteen specimens, all of which I have been able to examine, 
are one species (dawsoni) , I have used them as a basis of the following 
account of this insect. 
Wings (Figure 1) : The fore wing, which is completely preserved 
in several specimens, is from 45-48 mm in length, and from 10-12 mm 
in width. The type specimen has a fore wing length of 45 mm and a 
width of 10 mm. The hind wings of the several specimens are about 
the same dimensions as the fore wings but are somewhat narrowed 
basally. The costal area of the fore wing narrows abruptly just at the 
level of the separation of CuP and iA. In the hind wing the costal 
space is not narrowed at this point, continuing its full width as far as 
it is preserved in all specimens.
