. 



Elongate, depressed, shining, nigro-piceous, the rostrum, base of the antennae, and tips of the tarsi ferruginous. 

 Head depressed between the eyes, the latter small, transverse, and separated above by considerably less 

 than the width of the rostrum ; rostrum feebly curved, cylindrical, comparatively slender, about three-

fourths the length of the prothorax, sparsely, finely punctate, the punctuation coarser at the base, the 

 antenna) inserted just behind the middle. Prothorax as long as broad, somewhat conical, rounded at 



the sides posteriorly, the subapical constriction conspicuous on the flanks, scarcely traceable above ; 

 densely, rather coarsely punctate, the punctures becoming more diffuse along the middle of the disc. 

 Scutellum smooth. Elytra long, wider than the prothorax, parallel in their basal half, bluntly, conjointly 

 rounded at the tip ; coarsely, deeply punctate-striate, the interstices narrow, convex at the apex, and 

 finely uniseriate-punctate. Anterior coxae separated by their own width. Beneath somewhat coarsely, 

 closely punctate ; metasternum flattened down the middle posteriorly, ventral segments 1 and 2 with a 

 shallow median groove. Anterior tibiae angularly dilated and ciliate at the middle within. Third tarsal 

 joint widened and sub-bilobed. 

 Length 2-f, breadth -| millim. ( <5 .) 



Hab. Guatemala, Purula in Vera Paz (Champion). 



One specimen, evidently a male, to judge from the ventral excavation. More 

 elongate and less convex than S. armatus, the rostrum longer, smoother, and more 

 slender, the antennal club less acuminate, the transverse subapical groove of the 

 prothorax obliterated above, the elytra longer, more coarsely and not so deeply 

 punctate-striate, the tibiae less acute at the inner apical angle.

rufo-piceous. Head almost smooth, flattened between the eyes, the latter transverse, oval, and slightly 

 prominent ; rostrum moderately stout, curved, rather long, closely punctate, the antennae inserted just 

 beyond the middle, the club acuminate-ovate. Prothorax a little longer than broad, gradually narrowing 

 from near the base to the strong subapical constriction ; densely punctate, except along the narrow, 

 smooth, abbreviated, median line. Elytra considerably wider than the prothorax, parallel at the base, 

 gradually narrowing from about the middle, conjointly rounded at the apex ; punctato-sulcate, the sutural 

 stria broader and deeper than the others, the interstices becoming very narrow outwards, convex on the
