CALANDRIDA—CALANDRIN 2. 145 
more than half its shorter diameter, the facets distinctly visible with a power 
of 14 diameters, or about 0°02™ in diameter; rostrum very strongly arcuate, 
most strongly in the middle, so that the two extremities are nearly at right 
angles to each other, very slender, and fully two-thirds as long as the body; 
funicle and slender elongate pointed ovate club of antennz together about 
half as long as the rostrum, the first joint of the funicle slightly longer and 
considerably stouter than the second. Prothorax large and stout, scarcely 
half as high again as long, tapering moderately with rounded sides, the 
surface densely and not very finely punctate. Elytra about twice as long 
as broad, with deep and sharp, moderately slender, faintly punctate strize, 
the interspaces flat and very sparsely and faintly rugulose. Legs moder- 
ately long, the tibix not very slender, the third tarsal joint with rather 
large and rather slender lobes. 
Length, excluding rostrum, 6"; rostrum, 4:25™; height, 2:6™™. 
Florissant, Colorado. One specimen, Nos. 12035 and 12765. 
Family CALANDRID “4. 
This family was not very well represented in America in Tertiary times, 
its proportion of species to the whole body of Rhynchophora standing some- 
what below the present proportion. One of its existing subfamilies, the 
Rhininee, represented in America to-day by only a single species, is unknown 
in both the European and American Tertiaries, but the other two subfamilies 
occur in each country, and in proportions not greatly differing from those 
now existing, though in both countries the Cossoninze appear to stand a little 
above, the Calandrinz a little below, their present numerical importance. 
The total number of fossil species known is sixteen, of which the larger 
portion come from America. 
Subfamily CALANDRIN A. 
Of the three tribes into which the existing American species of this 
subfamily fall, the Rhynchophorini alone are not represented in Tertiary 
' deposits; the other two are found both in Europe and America, but with 
more species in the latter. The Sphenophorini are as now, but by no 
means to the same extent as now, the most numerous.
