rugulosely punctate. Prothorax strongly transverse, rounded at the sides, about equally narrowed in 
front: and behind, densely, rugulosely punctate. Elytra oblong, considerably wider than the prothorax, 
subparallel in their basal half, the humeri rounded; very finely and shallowly punctate-striate, the 
interstices almost flat, faintly punctulate, and each with a row of setigerous impressions similar to those 
of the strie. 
Length 24 millim.

UDEUS, gen. nov. 
ostrum rather slender, parallel-sided, about as long as the prothorax, the scrobes descending to the lower 
anterior margin of the eyes; antenne inserted at the middle of the rostrum, the scape reaching to beyond 
the middle of the eyes, the funiculus 6-jointed—joint 1 rather stout, 2-6 slender, very slightly increasing 
in width, all longer than broad,—the club ovate, acuminate; eyes lateral, rounded, large, prominent, 
coarsely facetted ; head convex, sunk into the prothorax to near the eyes; prothorax narrow, transverse, 
convex, truncate at the base and apex; scutellum very small, triangular; elytra oblong, truncated at the 
base, much wider than the prothorax, coverimg the pygidium ; anterior coxe globose, separated by a very 
thin lamina; anterior portion of the prosternum rather broad, truncate in front; ventral segments 1 and 
2 connate at the middle, 3 and 4 shorter than 2 or 5, the sutures straight; femora clavate and each 
armed with an acute triangular tooth; tibie narrow, obliquely truncate at the tip; tarsi slender, 
sparsely villose beneath, the third joint bilobed, the fourth very slender and as long as 1 and 2 united, 
the claws simple, divergent ; body oblong-ovate, pubescent. 
This genus includes a single species from Mexico and Guatemala. It is nearest 
allied to HKugnomus, a New Zealand form, but has a slender 6-jointed funiculus to the 
antennz, the antenne themselves being inserted at about the middle of the rostrum, 
and the head is more deeply sunk into the prothorax. ‘The vestiture consists entirely 
of fine pubescence. ‘The insect has much the facies of a small pallid Rhynchites.

Rather depressed, shining, somewhat thickly pubescent, testaceous, the eyes black. Head finely punctate, the 
rostrum smoother, the latter feebly curved and somewhat flattened. Prothorax subcylindrical, transverse, 
abruptly narrowed and constricted in front, transversely grooved before the apex, the surface closely, very 
finely punctate, the disc sometimes with a shallow transverse depression on either side and a smooth 
longitudinal space in the centre. FElytra oblong, about twice the width and three and one-half times the 
length of the prothorax, punctate-striate, the interstices flat and very finely rugulose. Beneath finely 
punctate. Venter in the g with a large, oblong, subquadrate depression in the middle at the base 
extending to near the apex of the second segment. ‘ibis very feebly mucronate at the inner apical 
angle in the d. 
Length 24-3 millim. (¢ @.)
