154 RHYNCHOPHORA. 
wider than the prothorax at the base, narrowing from a little below the rounded shoulders to the apex, 
flattened on the disc anteriorly, compressed laterally ; coarsely punctate-striate, the interstices convex and 
faintly punctulate. Femora each with a long triangular tooth, and a minute tooth exterior to this ; tarsal 
claws with a long tooth. 
Length 4, breadth 13 millim. (<¢.) 
Hab. Panama, Tolé (Champion). 
One specimen. Smaller and less robust than L. fusiformis, the eyes more narrowly 
separated, the prothorax parallel at the sides behind and without median vitta, the 
elytra without patches of denser pubescence at the base, this latter being reduced to a 
broad median fascia and two irregular fascie beyond it. 
5. Lonchophorus verruciger, sp.n. (Tab. IX. figg. 15, 154, 3.) 
Elongate, somewhat fusiform, shining, rufo-piccous, the apex of the abdomen testaceous ; sparsely clothed 
with rather long, decumbent, fulvous hairs, the pubescence on the elytra irregularly scattered and confined 
to the depressed portions of the disc, covering a curved space at the base of each; the under surface and 
the base of the femora with white hairs. Head finely punctate, deeply foveate above the eyes; rostrum 
feebly curved, about twice as long as the prothorax, seriate-punctate at the sides to beyond the middle 
and sparsely punctulate thence to the apex, the antenna inserted at two-fifths from the tip, joint 1 of the 
funiculus as long as 2 and 8 united. Prothorax transverse, compressed laterally and transversely 
depressed behind, constricted aud abruptly narrowed in front and slightly widened at the base ; closely, 
finely punctate, the disc with six small smooth tubercles—four in a transverse row before the middle and 
two behind them. Elytra elongate, gibbous, very much wider than the prothorax, greatly compressed at 
the sides (which are vertical from about the fourth row of punctures), and gradually narrowing in a 
straight line from the broadly swollen, subangularly prominent humeri; very finely punctate-striate, the 
striee much interrupted on the disc and deeply impressed at the base only, each elytron with eight large 
oblong or rounded smooth prominences on the inner part of the disc—one at the suture some distance 
below the base, six others (placed in pairs) between (and exterior to) this and the apex, and one on the 
fifth interstice below the humeral callus,—the interstices smooth and quite flat exterior to them. First 
ventral segment depressed in the middle at the base. Femora each with a triangular tooth, that on 
the anterior pair large, and also with a minute tooth exterior to this ; tibiw sinuate within, the anterior 
pair only unguiculate; tarsal claws with a long tooth. 
Length 74, breadth 34 millim. (d.) 
Hab. Costa Rica, Rio Sucio (Rogers). 
One specimen. A very remarkable species and difficult to describe in an intelligible 
manner. ‘There is an allied, unnamed form from South America in the British Museum. 
6. Lonchophorus nitidus, sp.n. (Tab. IX. figg. 16, 16a, 3.) 
Elongate, subfusiform, shining, varying in colour from black to ferruginous, sometimes piceous or nigro-piceous 
with the suture ferruginous; above very sparsely, and beneath somewhat thickly, clothed with rather long, 
white, decumbent: hairs, the hairs on the elytra here and there clustered together in small fascicles*. Head 
finely punctate, foveate above, smooth between the narrowly separated eyes; rostrum ( ) slender, nearly 
twice as long as the prothorax, finely seriate-punctate to beyond the middle and thence to the apex sparsely 
punctulate, (@) longer and more curved, the antennew inserted at about one-third from the tip in the ¢, 
and at about two-thirds from it in the @, joint 1 of the funiculus as long as 2-4 united. Prothorax 
transverse, narrowed and constricted in front and slightly sinuate at the sides behind, the entire surface 
coarsely, irregularly punctate. Elytra elongate-triangular as scen from above, much wider than the 
prothorax at the base, compressed laterally, so as to appear gibbous beyond the middle, and abruptly 
* The hairs are not shown in our figure.
