162 RHYNCHOPHORA. 
gibbous, nodose elytra by the tarsal claws being armed with a very small tooth, these 
appearing simple at first sight. The vestiture of the prothorax is very sparse on the 
median third. The dark elytral fascie are angulated and interrupted, and the humeri 
are very prominent. The claw at the apex of the anterior and intermediate tibie 1s 
unusually long. 
A, sextuberculatus-group. 
6. Anthonomus sextuberculatus, sp.n. (Tab. IX. figg. 22, 22a, 2.) 
Oblong, rufo-piceous, the rostrum (except at the tip), the antennex, the anterior femora and tibie in part, the 
intermediate and hind legs, and the apex of the abdomen ferruginous ; clothed with a scattered pallid or 
ochreous squamiform pubescence, which is coarser on the prothorax, the larger elevations on the elytra 
each with a dense cluster of long, erect, ochreous setee and the ninth interstice also with a small cluster 
of sete beyond the middle; the pubescence of the under surface whitish. Head rugulose, the eyes small, 
rounded, prominent ; rostrum slender, shining, feebly curved, very elongate, tricarinate in its basal half, 
almost smooth beyond, the antenne inserted at about the middle, joint 1 of the funiculus twice as long 
as 2. Prothorax broader than long, rounded at the sides, narrowed behind and narrowed and constricted 
in front, transversely convex at the middle, densely, finely punctate. Elytra moderately long, one-half 
wider than the prothorax, subparallel in their basal half, with obliquely truncated, angularly projecting 
humeri; deeply and rather coarsely punctate-striate, the interstices rugulose, convex, 3 with a large, 
oblong, setigerous prominence a little before the middle, and 2 with a smaller one nearer the apex, 
5 strongly raised at its point of termination, and 4 with a subangular prominence below the base. 
Anterior femora strongly clavate, armed with two triangular teeth, the inner one very large, the outer 
one small; intermediate and hind femora each with a small tooth ; tarsal claws with a long tooth. 
Length 33, breadth 13 millim. (Q.) 
Hab. Mexico (Salié). 
One specimen only of this curious species has been received. It is readily recog- 
nizable by the large setigerous tubercles on the elytra and the angularly projecting 
humeri. A. seatuberculatus somewhat resembles the N.-American Tuchypterus 
quadrigibbus (Say); but in that insect the hind tibie are unguiculate at the apex, 
the anterior femora are more feebly clavate, the rostrum is stouter, and the elytral 
elevations are fewer in number and without sete. 
7. Anthonomus nodifer, sp.n. (Tab. IX. figg. 23, 234, 3.) 
Oblong, rugulose, opaque, rufo-piceous, the rostrum, antenne (the club excepted), and legs testaceous, the 
femora mottled with fuscous at the middle; thickly clothed with small scales, which are mostly ochreous 
in colour, the elytra with a few small whitish spots and with oblong bare spaces on each interstice, the 
larger elevations setose, the squamosity of the prothorax somewhat coarse and mottled, the legs with rather 
long hairs. Rostrum feebly curved, slender, considerably longer than the head and prothorax, finely 
punctate and faintly carinate, smoother and shining at the tip, the antennz inserted at one-third from 
the apex, joint 1 of the funiculus twice as long as 2; eyes prominent. Prothorax a little broader than 
long, rounded at the sides, narrowed and constricted in front, and slightly narrowed behind. LElytra 
oblong, convex, much wider than the prothorax; finely punctate-striate, the interstices feebly convex, 
2 with a very prominent setigerous tubercle at about the middle and another towards the apex, 4 with a 
smaller subangular prominence below the base and another on the apical declivity, and the others here 
and there feebly nodose, the humeri obliquely swollen. Anterior femora strongly clavate, and armed
