52 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
LACHNOPUS Schonherr. 
A characteristic West Indian genus with about forty species. A single 
one is found in Florida. That two species should occur in the Tertiary 
beds of Florissant is an indication of the warmer climate of Oligocene times 
in that region. 
The species here referred to Lachnopus are among the largest of our 
fossil Rhynchophora and much larger than the single species living in the 
United States, but smaller than many exotic forms. They (or at least the 
best known species) appear to differ from Lachnopus in some important 
features, such as the direction of the antennal scrobes and the length of the 
scape, perhaps also in the form of the thorax; and though the two species 
here described have somewhat differently formed legs, the larger and least 
known species agreeing best with living Lachnopi, they yet agree so well 
in general features that it has seemed best not to separate them.

Pl. u, Figs. 8, 12. 
Form moderately stout, oval. Head and rostrum considerably longer 
than the thorax, very finely and densely punctured, the rostrum consider- 
ably longer than the head, which is scarcely longer than the diameter of the 
large round eye. Antennal scrobes running against and not beneath the 
eye, the scape passing but little the anterior margin of the same; funicle 
and club together about twice as long as the scape, the club oval. Thorax 
almost twice as high as long, truncate at base, slightly fuller in the lower 
part of the sides, the base bisinuate, the surface very compactly and some- 
what finely punctate. Elytra oblong-oval, less than two and a half times 
longer than broad, with rows of moderately large, sharply impressed, circu-
