APION SMITHII. 
Pliy,) Pig. 2. 
This, the largest of the Florissant ‘species, differs strikingly from the 
others and from all modern species known to me in the great length of the 
head, as well as in the great length and looseness of the antennal club, so 
that I question whether it should fall here. The general form appears to be 
as in the group Ventricosum. The head is considerably longer than the 
thorax and longer than broad, tapers with full sides and rounded front nearly 
from the base, and is nearly smooth but transversely wrinkled; the rostrum 
is only alittle longer than the head, very stout (for Apion) and equal, scarcely 
arcuate, well rounded at the tip, with no expansion except at extreme base; 
the loose club occupies nearly two-fifths of the antennee, which are longer 
than the beak by the length of the apical joint. Thorax very short and 
transverse, broadest at the base but scarcely tapering, a little arched above, 
the surface very distantly, rather coarsely but not heavily punctate. Elytra 
not clearly and fully preserved in any specimen, but the striation appears 
to be feeble, and their punctuation rather coarse. Legs with.very stout and 
large fore femora, but in no way abruptly clavate.
