Material examined: Holotype No. 2042 (Museum of Compara- 
tive Zoology, Harvard University), Oligocene of Florissant, Colo- 
rado. 
Family Argidae 
Sterictiphora konowi (Rohwer) 
Figure 3 
Schizocerus konowi: Rohwer, 1908b: 591. 
The venation of this species is very similar to that of Sterictophora 
Billberg; however, it differs in that C is not dilated towards the 
top and by having a long and narrow praescutum bordered by broad 
furrows, with close transverse ribs inside them. 
Material examamined: Holotype No. 4156 (Natural History 
Museum of Colorado, Boulder, Colorado), Oligocene of Florissant, 
Colorado. 
Family Cimbicidae 
Eopachylostictia byrami (Cockerell) 
Figure 4 
Amasis byrami: Cockerell, 1925: 10, pi. 2, fig. 5. 
Eopachylostictia byrami: Malaise, 1945: 14. 
Genus Eopachylostictia was established by Malaise (1945) for 
Amasis byrami Cockerell mainly on the basis of the small photograph 
in Cockerell's paper of 1925. A larger and clearer photograph 
received from Professor Carpenter confirms Malaise’s interpretation 
of the features of this fossil insect. 
Material studied: Photograph of Holotype No. 69181 (United 
States National Museum, Washington), Eocene of Green River 
Shales, Colorado. 
Family Tenthredinidae 
Athalia (?) wheeleri (Cockerell), comb. nov. 
Figure 5 
Eriocampa wheeleri: Cockerell, 1906: 500, fig. 2. 
The venation is similar to that of Athalia Leach, but it differs 
profoundly by the strong C of the fore wing. Other Tenthredinidae 
with such a C (some Selandriinae, Nematinae, etc.) possess quite 
a different venation. The fossil differs sharply from Eriocampa 
Hartig by its venation (especially in the region of the base of 
RS + M) and by the smooth thoracic sclerites. However, too many 
features are indiscernable in the photograph (and probably in the 
holotype) to place this fossil in Athalia with confidence.
