with narrow, elongate, overlapping white, ochreous, and dark brown scales (those on the elytra arranged 

 in about two rows along each interstice and one along each stria), the prothorax with a dense cluster of 

 larger, imbricate white scales in the middle behind (covering the scutellum), and the elytra with two 

 oblong patches of similar scales along the suture — one near the base, indistinct, the other, larger, broader, 

 and sharply defined, beyond the middle ; the vestiture of the under surface and legs white and ochreous, 

 the scales on the meso- and metasternal side-pieces larger and pure white. Rostrum arcuate, rather 

 stout, closely punctate, the antennae inserted far beyond the middle. Prothorax transverse, deeply 

 sinuate at the base, the sides subparallel behind; densely punctate. Elytra much wider than the 

 prothorax, feebly rounded at the sides, somewhat flattened on the disc anteriorly, strongly and separately 

 rounded at the apex ; finely punctate-striate, the interstices densely, rugulosely punctate,

6 (a). Sibinia solarieUa, sp. n. 



Short ovate, black, the base of the antennae, and the tarsi in part, ferruginous ; somewhat thickly and 



uniformly clothed with narrow, hair-like, whitish-cinereous scales, which are condensed into a faint 

 streak along the basal portion of the elytral suture, the elytral interstices each with a line of slightly 

 raised setiform scales down the middle ; the scales on the under surface larger and wholly white. 

 Rostrum arcuate, a little longer than the prothorax, closely punctate. Prothorax transverse, arcuately 

 narrowing from near the base, densely punctate. Elytra wider than the prothorax, separately rounded 

 at the apex ; punctate-striate, the interstices wider than the striae, closely punctate.

Ildb. Nicaeagua, Managua (Solari). 



Five specimens. Separable from the allied S. americana, Ch., and S. melina, 

 Faust, by the conspicuous line of raised setiform scales down each elytral interstice.

6 (b). Sibinia albidula, sp. n. 



Ovate, narrow, nigro-piceous, the rostrum, antennae, and legs ferruginous ; rather sparsely clothed with fine, 

 hair-like, white scales, the elytral interstices each with a line of conspicuous white setae. Eostrum about 

 as long as the prothorax, tapering outwards, bare and shining at the tip. Prothorax transverse, 

 narrowing from the base, densely, finely punctate. Elytra wider than the prothorax, separately rounded 

 at the apex ; punctate-striate, the interstices about as wide as the striae, densely punctate.

Hab. Nicaragua, Corinto (Solari). 



One specimen. Smaller than S. solarieUa, the vestiture finer, sparser, and wholly 

 white, the prothorax somewhat conical, the legs ferruginous, &c.
