56 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
eye, the funiculus and club together slightly shorter than the thorax; eye 
circular (represented too large on the plate). Prothorax much higher than 
long, truncate at each extremity, with no fimbrize, the surface punctato- 
rugose. Elytra not very elongated, well arched posteriorly, with linear 
series of rather large circular punctures widely separated from each other 
and represented in the cast by rather pronounced lenticles, separated from 
ach other by considerably more than their own diameter over most of the 
elytra, but subconfluent, forming ridges (or strie) toward the apex. ‘The 
hind femora nearly reach the tip of the abdomen. 
Length, including rostrum, 7"; of head and rostrum, 1°75"; of elytra, 
41"; height of body posteriorly, 2°8™". 
This species, though not very closely resembling our living 0. epicae- 
roides Horn, seems to agree with it in all generic features, excepting in the 
somewhat shorter antennal scape and the completely circular eye; the sec- 
ond abdominal segment appears, also, to be relatively longer, and when 
more fully known, it may have to be generically distinguished. 
Florissant, Colorado. One specimen, No. 6544. It is possible that 
another but a poorly preserved specimen, No. 5075, may belong here.

The six fossil species from America referred to this tribe are equally 
divided between Phyllobius and Scythropus, and being altogether absent at 
Florissant, may be regarded as typical of the Gosiute fauna. Curiously 
both genera may be regarded as gerontogeic. The tribe is represented in 
European Tertiaries* by Phyllobius and Polydrosus, said by Burmeister to 
occur in amber. 
PHYLLOBIUS Schénherr. 
This is an Old World type, with numerous species largely confined to 
the northern hemisphere A single European species has been found, per- 
haps occurring by accident, in Canada, and another is credited to Mexico. 
Very close to this genus, if not belonging to it, are three fossil species in 
the Roan mountains, White river, and Green river Tertiaries, but none 
are found at Florissant. Burmeister says he has seen a species of Phyllo- 
bius in amber, but otherwise it has not before been recognized among the 
fossils.
