tures in the basal third of the wings. There is usually a thickened 
ridge, resembling a vein, between M and Rs, close to the origin of 
the latter and in an oblique position. From her study of the Com- 
mentry spilapterids, Dr. Kukalova concluded that the ridge was 
present in all Homaloneura but was absent in Spilaptera. In S. 
packardi (type species of the genus), the oblique ridge was absent, 
although normal transverse cross veins were present in the corres- 
ponding area of the wing. In the only other species of Spilaptera 
previously known (libelluloides) the nature of this particular area 
of the wing is unknown because that part of the wing is not pre- 
served. 
In the holotype specimen of S. am eric ana > described above, the 
cuticular, oblique ridge is present (see figure 10), but in the para- 
type there is no oblique structure, only the normal cross veins. In 
view of the very close similarity of these two fossils in other re- 
spects, we are inclined to infer from this scant evidence that the 
oblique ridge is, in fact, a modified cross vein and that the degree 
of its inclination may vary within the species.

In the collection of Helen and Ted Piecko, there is an interesting 
specimen of Eubrodia dabasinskasi , a species originally described from 
a single wing, lacking only the base (Carpenter, 1967). The new 
specimen (HTP433, Pit Eleven) consists of the body, which is
