104 TERTIARY RHYNCHOPHO RCUS COLEOPTERA. 
NUMITOR CLAVIGER. 
Pl. u, Fig. 6. 
Head feebly punctate, the eye very large, removed from the prothorax, 
rounded ovate, transverse; rostrum moderately stout, moderately and regu- 
larly arcuate, as long as head and prothorax together, apparently feebly 
punctate. Prothorax a third higher than long, tapering only next the apex, 
gently arched above, heavily and profusely punctate. Elytra punctato- 
striate, but apart from that with distant, very deep and sharp, rather small 
circular puncta. Under surface profusely and rather heavily punctate, as 
are apparently the thickened portions of the femora. 
Length, excluding rostrum, 3°5""; rostrum, 1°5"™; elytra, 2°25™"; middle 
femora, 1:75""; height of body, 2™". 
Florissant, Colorado. One specimen, Nos. 11283 and 13616. 
SMICRORHYNCHUS $ (Gyzxpos, pdyzos), gen. nov. 
I venture to discriminate from Smicronyx and its allies among the 
Desmorhines a little weevil having the general form and aspect of Desmoris 
and agreeing well with it in size, but more nearly allied to the minuter 
species of Smicronyx in the equal length of the second and third joints 
of the funicle of the antennee; it differs from all the genera of this group in 
the equality of all three of the basal joints of the funicle. The beak is as 
long as the head and prothorax together, marked by a basal constriction, 
and is slightly enlarged throughout its apical half; the antennz are inserted 
before the middle of the rostrum, but the scape barely reaches the eyes; 
the first, second, and third joints of the funicle are a little elongated, equal, 
and equally slender, each about twice as long as broad; the remaining joints 
are a little shorter, the club rather stout ovate. Prothorax apparently with- 
out postocular lobes. The body is well arched, and highest in the middle 
of the abdomen, behind which the elytra are strongly though not abruptly 
declivent. 
A single species is known, and comes from Florissant.
