Gen. Cure. iii. p. 392°. 
Elongate, ferruginous, shining; a median vitta on the prothorax, a common, X-shaped patch on the elytra, 
extending from the humeri to near the apex, and the scutellum, densely clothed with appressed whitish 
pubescence, the rest of the surface clothed with scattered, decumbent, whitish hairs. Head finely 
punctate, carinate between the eyes; rostrum curved, rather slender, about as long as the entire body, 
seriate-punctate and quadrisulcate in its basal half, finely punctulate thence to the apex, the antennz 
inserted slightly before the middle, joint 1 of the funiculus very elongate. Prothorax broader than long, 
constricted and much narrowed in front and slightly widening behind, coarsely, confluently punctate, 
except along the space occupied by the median vitta, which is flattened and finely punctate. Elytra 
elongate, one-half wider than the prothorax at the base, compressed laterally, somewhat flattened on the 
disc and subtriangular as seen from above, the humeri flattened and broadly subangularly dilated ; 
coarsely punctate-striate, except upon the flattened space occupied by the dense white pubescence, the 
interstices convex and sparsely punctate, the fifth slightly callose at its apex. Legs elongate ; anterlor 
femora moderately clavate, armed with a large triangular tooth, which is feebly notched on the outer 
edge; intermediate and hind femora with a smaller triangular tooth ; tibie sinuate on their inner edge ; 
tarsal claws with a long tooth.

Hab. Nicaraaua, Chontales (Belt)—Braziu?, Rio Janeiro }. 
One specimen of this insect has been sent us from Nicaragua. Easily recognizable 
by the dorsally flattened, elongate-subtriangular elytra (which have a large, common 
X-shaped, white patch on the disc), and the extremely elongate rostrum in the female *. 
2. Lonchophorus fortis, sp. n. (Tab. IX. fig. 11, ¢.) 
Elongate, robust, shining, piceous, the head, rostrum, prothorax, and legs (the knees excepted), and a large 
patch at the base of each elytron, ferruginous, the apex of the abdomen flavo-testaceous ; the prothorax 
with a narrow median vitta, the elytra with a humeral patch, an irregular common fascia before the 
middle, and a very large apical patch, and the scutellum, thickly clothed with appressed whitish or 
ochreous pubescence, the rest of the surface with scattered, decumbent, long, whitish hairs. Head sparsely 
punctate; rostrum feebly curved, about twice as long as the prothorax, moderately slender, flattened 
above, sparsely punctate and carinate towards the base, for the rest smooth, the antenne inserted slightly 
before the middle, joint 1 of the funiculus elongate. Prothorax broad, transverse, rounded at the sides, 
much narrowed and constricted in front and slightly widening behind, coarsely, confluently punctate, 
except along the median line, which is finely punctate. Elytra elongate, much wider than the prothorax, 
flattened on the disc towards the base, lateraliy compressed, narrowing from the arcuately dilated humeri 
to the rounded apex, the humeri depressed within; deeply punctate-striate, the interstices convex and 
* Chevrolat incorrectly identified the sexes, and his figure no doubt represents a 2, and not a ¢ as stated.
