Cockerell — Eocene Fossils from Green River. 447 



Art. XLII. — Eocene Fossils from Green River, Wyoming / 

 by T. I). A. Cockerell. 



Plants. 



Firmianites gen. nov. (Buettneriaceae.) 



Rather large globose capsules, with apparently five carpels 

 (three visible in the type, one side of which is exposed), the 

 surface smooth. 



Firmianites aterrimus sp. nov. 



Capsule about 13-J- mm , long and broad, as preserved shining 

 coal-black, the longitudinal sutures evident, slightly raised 

 above the general surface. 



Hab. — On red shale, in the insect-bearing beds, Green River, 

 Wyoming. (Eocene.) These fruits closely resemble those of 

 the living genus Firmicma, found in China and Japan, and 

 extending in a single species to Africa. It is not impossible, 

 perhaps, that they actually belong to that genus, but it is no 

 doubt much more likely that they represent some allied type 

 no longer living. Among the described fossil fruits, there 

 is a distinct resemblance to Apeihopsis, which, however, has 

 many more divisions. 



An apparently related fruit is Palmocarpon corrugatum 

 Lesouereux, Tertiary Flora, pi. xi, f. 11. As this has more 

 than three carpels, it cannot be a palm ; it must be known as 

 Carpolithes corrugates. It is from the Basal Eocene at 

 Golden, Colorado. 



Coleoptera: Otioehynchid.e. 



Syntomostylus (? ) fortis n. sp. 



Length (excluding rostrum) 10-§- mm ; rostrum about 2^ mm y 

 robust ; elytra 7J- mcn long and 3 broad, with seven rows of very 

 large and strong punctures, becoming small and feeble apically ; 

 about the middle of the elytra there are about two punctures 

 to one mm.; eyes elongate ; thorax much broader than long, 

 rugose ; anterior femora moderately swollen ; hind femora 

 slender basally, but apically much swollen, their apices 

 nearly level with the tip of the abdomen ; elytra pointed 

 apically. The following measurements are in /jl : 



Greatest width of hind femora (near apex) 900- 



Breadth of rostrum about 850" 



Length of eye about 850* 



Breadth of eye about 375- 



Hao. — On red shale of Eocene age, Green River, Wyoming ; 

 collector unknown. This is much the largest of the Green
