458 CLASSIFICATION OF THE RHYNCHOPHOROUS COLEOPTERA. 
with the next about 4 from the base, or abbreviated at that p 
or interrupted, the continuation commencing behind the 
and extending to the tip. The prothorax is bisinuate at 
(Compsa, Brachystylus and Brachythysus), truncate or feebly 
rounded in Tanymecus, Aphrastus, and the genera with connate 
elytra. The eyes are rounded and the prothorax not lobed in " 
of our genera. 7

Next to this tribe come the Entimini, sale: and brilliant insects 
of South America; the rostrum is stout, not so broad as in the 
last two tribes, deeply emarginate at tip, perpendicular on the 
sides, thickened below at the tip, with the antennal grooves deep 
and oblique; the apical scar of the mandibles is very large, o 
cular and not prominent. The eyes are pointed below, and He 
prothoracic lobes large. The prothorax is comparatively 5 
and bisinuate at base; the elytra at base very broad, with prom- 
inent humeri, gradually narrowed and acute behind; the 0 
most stria is entire. The edge of the elytra and the 
sutures are densely fringed with short hair; the —

Two insects presenting anomalous characters remain to be 
sidered, each indicating a separate tribe. 
The first is found abundantly in Oregon; the beak is two 5 
a half times as long as the head, moderately slendes dilated 
auriculate at tip, which is deeply emarginate; the groo”"

tinctly in an oblique direction; the apical scar of the 1
