sieve, Huon 3. 
Heaa with the same surface sculpture as the thorax, but less pronounced; 
the eye circular, situated low down on the sides, removed from the front 
border of the prothorax ; beak longitudinally striate, as long as head and 
thorax together, apically imperfect in the single specimen, very gently and 
regularly curved; antennz inserted distinctly before the middle of the beak, 
the seape attaining the middle of the eyes, the club stout oval ; joints of the 
funicle not clearly determinable. Prothorax one-third higher than long, 
gently tapering forward, with prominent hind angles and the surface closely 
and rather coarsely and distinctly punctate. Elytra less than twice as long 
as broad, broadly rounded at tip, exposing the pygidium, very sparsely and 
feebly punctate, each puncture at the base of a short hair and with only 
the feeblest and vaguest signs of any longitudinal striation.

Tribe ANTHONOMINI. 
This tribe, now represented in America by a considerable number of 
species, though not rich in generic types, and entirely absent from European 
Tertiary deposits, is one of the most important of the Curculionine in the 
Tertiaries of America, the number of generic types which have been dis- 
covered being as great as now, Elleschus being the only one not recognized, 
and its place is made good by an extinct type, Cremastorhynechus, with a 
single species. Acalyptus, Orchestes, and Macrorhoptus have each a single 
species, Coccotorus two, and all of these come exclusively from Florissant; 
as in the existing fauna, however, Anthonomus is far the best represented, 
being in fact the richest species of any of our fossil Rhynchophora, having 
ten species tolerably numerous in individuals, and all but two, which come 
from the Gosiute fauna, are likewise restricted to Florissant.
