the funicle; prothorax as in the preceding, except that it is more distinctly 

 wider than long and with more conspicuous punctures on the basal lobe; 

 scutellum similar, quadrate; elytra similar in form and proportion, though a 

 little narrower and somewhat more narrowly rounded at apex, with the striae 

 and punctures slightly more distinct, the second stria similarly ending at 

 base in a small elongate fovea; posterior legs and the abdomen nearly similar 

 in both sexes, the external tibial tooth moderate. Length 9.1-9.8 mm.; 

 width 5.9-6.35 mm. Brazil (Chapada). Eight specimens., .porcinus n. sp. 



Body rather large, subrhombic, convex, smooth and very shining, black, the upper 

 surface dark piceous, gradually black on the elytra apically; beak three- 

 fourths as long as the prothorax, distinctly and evenly arcuate, rather thick, 

 the flattened sides coarsely and closely, the upper surface more finely and 

 rather closely punctate throughout; head deeply, not densely punctate, 

 more finely and sparsely between the eyes; antennae rather behind the middle, 

 the club not quite as long as the funicle; prothorax barely wider than long, 

 the sides slightly converging and feebly arcuate, more arcuate anteriorly to 

 the arcuate tubulation, which is a little more than a third the basal width; 

 surface subumbonately prominent at the summit of the flanks medially; 

 basal lobe with scattered punctures, broadly rounded, feebly sinuate medially, 

 without lateral impressions; scutellum smooth, quadrate, feebly and evenly 

 convex, the apex sinuate; elytra cuneate, with arcuate sides and broadly 

 rounded humeral prominences, longer than wide, two-thirds longer than 

 the prothorax and only a fifth wider, remotely punctulate; striae fine and 

 almost obliterated; abdominal concavity strongly, densely punctate and 

 coarsely setulose, smooth at base; subbasal tibial spines acute. Length 

 9.7 mm.; width 6.25 mm. Brazil. Desbrochers des Loges . .longicollis n. sp. 



Body subrhombic, narrower, black, the upper surface rufo-piceous throughout, 

 shining, though faintly alutaceous; beak rather long, almost as long as the 

 prothorax and evenly, somewhat strongly arcuate, cylindric, rather finely, 

 loosely punctate; antennae submedial, piceous, with the club black and long, 

 as long as the funicle; prothorax nearly a third wider than long, the con- 

 verging sides barely at all arcuate, more so anteriorly to the tubulation; 

 basal lobe with a few fine punctures and feeble impressions laterally, the apex 

 truncate; surface subevenly convex; scutellum quadrate, finely, sparsely 

 punctate, black, shining, the apex feebly sinuate, with rounded angles; 

 elytra slightly elongate, fully a fourth wider than the prothorax, cuneiform, 

 the humeral prominences broadly rounded; striae very fine and subobsolete, 

 remotely punctulate; basal abdominal area transversely concave and smooth 

 at base, the remainder broadly convex and rather finely, loosely punctate, 

 impressed medially toward apex; subbasal tibial spines strong and .sharp. 

 Length 8.3 mm.; width 5.4 mm. Brazil (Chapada). December. 



ordinatus n. sp. 



Body smaller but of nearly identical outline, coloration and lustre; beak similarly 

 rather strongly, evenly arcuate and subcylindric, but rather more slender, 

 about as long as the prothorax, the punctures rather small, not dense but 

 distinct; head evenly, somewhat closely punctate, with a small punctiform 

 fovea between the eyes; antennal club a little stouter and less elongate; 

 prothorax as in the preceding, but with more evenly and strongly arcuate 

 sides from base to tubulation, the surface evenly convex; basal lobe with 

 rather strong punctures marginally, and with very faint lateral impressions, 

 the apex less broadly truncate; scutellum almost smooth, parallel, somewhat 

 longer than wide, sinuato-truncate at tip, the surface feebly declivo-concave 

 posteriorly; elytra in form and sculpture nearly as in the preceding, but with 

 slightly more obtuse tip and rather less broadly rounded humeral projections; 

 basal abdominal plaque strongly but loosely punctate, smooth and feebly
