110 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
CREMASTORHYNCHUS (ypepaoros, puyzos), gen. noy. 
The insect to which this name is given is unquestionably nearly allied 
to Anthonomus and Coccotorus, so far as its structure can be told. But it 
differs from them so clearly in one point, that I venture to separate it, viz, 
in the sinuosity of the suture at the sides of the body between the first and 
second abdominal segments, a character which I do not find in any other 
genus of living Anthonomini. In other respects it closely resembles the 
species I have here placed in Coccotorus. The beak is almost straight, and 
nearly as long as the head and prothorax together; the eye large and trans- 
verse, but not approximate above; all the femora are stout, but more strongly 
clavate, and the segments of the abdomen are of subequal length. 
A single species is known, and comes from Florissant.

CREMASTORHYNCHUS. STABILIS. 
Hy 
Piva, Pies 9: 
The body is rather stout and full, evidently tapering considerably for- 
ward from the base of the thorax. Head very short and fully twice as 
broad as long, the beak straight or almost straight, moderately slender, and 
but little shorter than the head and prothorax together; surface rather feebly 
and finely punctate, the punctures more or less run together longitudinally. 
Thorax rather rapidly tapering from the base, more than half as high again 
as long, rather coarsely and closely punctate, with numerous fine hairs. 
Elytra distinctly punctato-striate, the puncta separated by their own diame- 
ters, the interspaces sparsely and faintly punctate, and sparsely clothed with 
rather coarse hairs, each as long as the width of the interspaces. 
Length, excluding rostrum, 4°75""; rostrum, 1:25"; height at base of 
thorax, 1°65""; at middle of abdomen, 2°35™".

ANTHONOMUS Germar. 
A genus rich in species, over a hundred of which are known. It occurs 
in nearly every quarter of the globe, but is richest in numbers in Ameriea. 
In North America alone we have more than forty species widely distributed,
