Palaeochrysa creedei Carp. 
Palaeochrysa creedei Carpenter, 1935, Journ. Paleont., 9: 
265, fig. 3. 
This species, although similar to the following, is char- 
acterized by the extraordinary length of the basal Banksian 
cell of the fore and hind wings. 2 The holotype is No. 
4316 ab, Museum of Comparative Zoology. 
Palaeochrysa stricta Scudd. (Fig. 1)

There are ten Chrysopids (4462-4471) in the Creede col- 
lection which seem to be identical in every way with this

species, previously known solely from the Florissant shales. 
Since this is the only Creede species of those so far deter- 
mined which appears to be common to the two beds, I have 
included drawings of its venation. It should, however, be 
borne in mind that among the Recent Chrysopidae the vena- 
tion of closely related species usually shows no differences. 
2 In my account of the fossil Chrysopidae (Journ. Paleont., 9: 259-271, 
1935) the captions for figures 2 and 7 should be interchanged.
