82 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
Length, excluding rostrum, 4°"; rostrum, 1"; height in middle of ab- 
domen, 2". 
Florissant, Colorado. Four specimens, Nos. 8592, 8702, 9034, 13619. 
The species is named for the entomologist, Prof. John B. Smith, of New 
Jersey, the latest monographer of the genus in America. 
APION PUMILUM. 
Ply, Rigee7: 
Viewed from the side, the dorsal aspect is strongly arcuate. The head 
is nearly as long as the thorax, rounded conical, the surface transversely 
striate, beneath the eye punctate; eyes circular, not large, lying next the 
base of the beak, which is porrect and slender, but in the single specimen 
known is broken a little beyond the base; so far as can be seen it has exactly 
the aspect of that of A. curiosum. Thorax about half as high again as broad, 
scarcely tapering, very gently arcuate above the surface, with large and 
distant punctures, very different from those of any of the other species. 
Elytra apparently somewhat larger at base than the prothorax, very arcuate, 
fullest in the middle, rapidly descending behind, apparently less than twice 
as long as broad, with coarse, deep punctate striz. Legs obscure. 
Length, excluding rostrum, 2™"; elytra, 16"; height, 1™. 
This is the smallest of the fossil species.

APION CONFECTUM. 
PlSy, Biel 3: Pl x hie. 9: 
A pretty stout species, largest in the middle of the elytra, and behind 
that rapidly narrowing much as in the group Crassinasum of Smith, but not 
quite so rapidly. Head considerably higher than long, tapering with 
slightly arcuate sides, transversely faintly striate, the circular eye at the 
base of the beak and removed by about its own diameter from the front 
margin of the prothorax; beak slender, nearly half as long as the body, 
faintly arcuate, especially next the base where it is also a little tapering.
