64 TERTIARY RHYNCHOPHOROUS COLEOPTERA, 
not so long as even the apical breadth of the rostrum. Scrobes straight or 
gently arcuate, terminating at the eye, which they strike just above the lower 
edge. Second abdominal segment not longer than the two following to- 
gether, at least on the sides. 
A single species is known.

The head and prothorax are densely and rather finely subrugulose, on 
the head, excepting the rostrum, complicated by fine, close, transverse 
striations, and on the prothorax faintly showing signs of a longitudinal 
arrangement, and slightly coarser than on the head; the prothorax also 
shows, laterally, an arcuate rounded plica. The elytra are each about two 
and a half times longer than broad with straight linear series of rather large, 
deeply impressed rounded puncta separated in the same row by rather less 
than their own diameter; feeble signs in some places show that the inter- 
spaces were covered with semi-erect, not very fine hairs. 
Length, excluding rostrum, 85"; rostrum, 1-4"; height of body,

EUDIAGOGUS Scehonherr. 
This is a tropical American type with a meager number of species of 
which two occur in our Gulf states. A single species occurs fossil in 
America, first recognized at Green River, but since found also at White 
river and the Roan mountains, so that it is probably characteristic of the 
Gosiute fauna.

Three additional specimens which appear to belong here have been 
obtained from new localities, each specimen consisting of a pair of fairly 
preserved elytra or a single elytron only.
