476 RHYNCHOPHORA. 
S. Acalles quadrituberculatus, sp. n. 
Oblong-ovate, narrow, convex, shining, black, the antenne and tarsi ferruginous; thickly clothed (except 
upon the sides of the prothorax and elytra) with rather coarse brownish-ochreous scales, with scattered 
coarser scales or sete intermixed, the latter clustered together on the elytral elevations, the legs setulose. 
Head and rostrum densely, rugulosely, the tip of the latter more sparsely, punctate ; antenne inserted at 
the middle of the rostrum, joints 2-7 of the funiculus closely articulated, 2 much shorter than 1, the club 
ovate. Prothorax a little broader than long, constricted and narrowed in front and slightly narrowed 
behind; densely, finely punctate, the disc transversely depressed in front and flattened along the middle 
thence to the base. Elytra gibbous, ovate, not wider than the prothorax at the base, produced at the 
apex ; coarsely seriate-punctate, the third interstice with an oblong setigerous prominence below the base 
and another at the commencement of the apical declivity. (the latter oblique), and the fifth also a little 
raised before the middle, the outer ones almost flat. Ventral segments sparsely,somewhat coarsely punctate, 
1 and 2 connate, 5 long. Legs rather elongate, the femora unarmed, the anterior tibie sinuate within. 
Length 3, breadth 14 millim. 
Hab. Mexico, Oaxaca (/H6ge). 
One specimen. Very near A. rufotuberculatus, but a little less elongate, the scales 
shorter and more rounded, the setz coarser, the submedian prominence on the third 
elytral interstice setose and the other not reaching so far forward, the elytra not 
conjointly sublobate at thé base. 
9. Acalles rugulosus, sp. n. 
Oblong-ovate, shining, black, the antenne and tarsi ferruginous ; thickly clothed with oblong, intermixed 
brownish and fulvous scales, and also with a few scattered decumbent sete, the legs finely setulose. 
Head and base of the rostrum densely, the rest of the latter sparsely, punctate ; antenne inserted at the 
middle of the rostrum, joints 1 and 2 of the funiculus subequal in length, the club ovate. Prothorax 
nearly as long as broad, moderately rounded at the sides, narrowed and feebly constricted in front, 
subtruncate at the base; densely, finely punctate. Elytra convex, oblong-ovate, produced at the apex, 
scarcely wider at the base than the prothorax ; coarsely seriate-punctate, the interstices rugulose, 3-7 
here and there longitudinally raised, 2 also a little raised beyond the middle. Ventral segments sparsely, 
finely punctate, 2 nearly as long as 5, 3 and 4 very short, the first suture arched. Legs stout, short, the 
femora unarmed. 
Length 4, breadth 13 millim. 
Hab. GuatemaLa, Calderas 7000 feet, on the slope of the Volcan de Fuego 
(Champion). 
One specimen. Separable from most of its allies by the non-sulcate disc of the 
prothorax and by the presence of longitudinal elevations on the disc of the elytra. It 
approaches A. fulvovittatus. 
10. Acalles cunctans. (Tab. XXIII. figg. 16, 16 a.) 
Acalles cunctans, Boh. in Schénh. Gen. Cure. viii. 1, p. 418°. 
Hab. Mexico, Vera Cruz (Mus. Holm.). 
Distinguishable by its ovate form; the carinate rostrum; the strongly transverse, 
densely punctate prothorax, the sides of which form an almost continuous outline with 
those of the elytra; the feebly raised seriato-granulate elytral interstices ; the rather
