like the thorax, but much more sparsely.

Plova, Bie: 5: 
To this genus I refer a single species with large transversely oval eyes, 
not closely approximate above, but so closely as to make the front narrower 
than the beak, with obtuse hind angles to the prothorax, and with all the 
aspect and structure of one of the Anthonomini. The head is about half as 
high again as long, with a finely punctate surface; the beak is somewhat 
longer than the prothorax, somewhat arcuate and equal; the antennal serobe 
scarcely attains the eye, and is apparently inserted slightly beyond the 
middle of the beak; the funicle and club together are slightly longer than 
the scape, and slender, the final joints of the funiculus gradually enlarging 
to the gentle club, much as described for M. estriatus Lec., but slenderer. 
Thorax much more than half as high again as long, well rounded, not taper- 
ing greatly, rather coarsely punctate. Elytra fully twice as long as broad, 
subequal, except apically, punctato-striate, the interspaces feebly and finely 
punctulate.

Tribe PRIONOMERINI. 
This small tribe, unknown in the Old World, whether in recent or 
Tertiary times, is represented in our Tertiary deposits by a single species 
of Prionomerus at Florissant.
