108 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
ACALYPTUS Schénherr. 
A genus containing only three or four species, mostly European; but 
one found in the East Indies; one of the European species oceurs also in 
North America, and a single fossil species has been found at Florissant. 
ACALYPTUS OBTUSUS. 
Pl. v1, Fig. 10. 
I refer to this genus one of the smallest of our fossil Anthonomini from 
its close general resemblance to A. rwjipennis Schonh., figured by Du Val, 
with entire agreement in all the details of the structure which can be studied. 
The body is stout and compact, tapering considerably and rather rapidly 
from the middle of the abdomen forward. The head is subeconieal, half as 
high again as long, feebly punctate and below transversely, finely, and 
feebly striate; the eye circular, of about the diameter of the beak, with 
about sixty large facets, each slightly less than 0-015" in diameter; the 
beak is long and slender, somewhat longer than head and thorax together, 
gently arcuate and equal. The antennze appear to be inserted and formed 
precisely as in A. rufipennis, with the same proportional lengths, so far as 
can be seen; the club, however, is obscure. The thorax is well rounded, 
tapering, about half as high again as long, very coarsely punctate. The 
elytra are well arched, much broader in the middle than elsewhere, and 
rather coarsely punctato-striate, and the interspaces show feeble signs of 
sparse and shallow punctuation. 
Length, excluding rostrum, 2-4"; rostrum, 0-7"; height of body at 
base of thorax, 0-77"; at middle of abdomen, 1:2™". 
Florissant, Colorado. -Three specimens, Nos. 490, 4517, 9076. 
COCCOTORUS LeConte. 
This genus was founded upon a single species, which is still the only 
one known, and is found in the United States east of the Rocky mountains. 
It is interesting to find two fossil species both of which occur only at 
Florissant, and hence are probably characteristic of the Lacustrine fauna.
