quarters of the globe. In the New World it is most abundant in the West 
India islands, and only a couple of species occur in the United States east 
of the Mississippi. Two species are found fossil in our Tertiaries—one at 
Florissant, Colorado, the other at Green River, Wyoming.

TROPIDERES VASTATUS. 
Phin, ies: 
A single specimen, not very clearly preserved, lying upon its side, 
represents this species. It is clearly related very closely to Tropideres, if 
it does not belong to the genus in the restricted sense in which it is used by 
LeConte. It seems to have been moderately stout, uniformly black, and 
uniformly, densely, and very delicately granulose, or shallowly punctate, it 
is hard to say which. The beak is moderately stout, shorter than the head; 
it is badly represented in the plate, having an appearance wholly unlike a 
Tropideres; the antennze not much longer than the beak, the club composed 
of three subequal joints, fully twice as broad as the preceding, together 
forming an oval mass about two and a half times longer than broad; the 
eye is round oval, entire, transverse, and moderately prominent. The pro- 
thorax.is largest, though but slightly, at the prebasal ridge, and tapers for- 
ward remarkably little; the elytra have rather finely punctured strize, so 
closely crowded as to give the striz the appearance in the cast of nearly 
continuous ridges. 
Length, 6™"; height, 2°75™™; length of antenne, 1-6™.

TROPIDERES REMOTUS. 
Pl. xu, Fig. 14. 
A single specimen, in which, unfortunately, the antenne are not pre- 
served, seems to belong here. The head is smooth, twice as broad as long, 
with rather small, circular, prominent eyes; the beak a little broader than
