Brazilian Baring 403 



Form more oblong, much smaller in size, deep black and polished; beak (9) 

 rather thick, evenly and feebly arcuate, very evenly cylindric, not tapering, 

 minutely, sparsely punctate throughout and rather short, barely as long as 

 the prothorax; antennae nearly normal and just visibly behind the middle; 

 prothorax a third wider than long, the sides very feebly converging and 

 just visibly arcuate, more rounding but only feebly oblique in apical third 

 to the very broad and gradually formed tubulation, which is nearly two- 

 thirds as wide as the base; surface remotely and very finely punctulate, 

 somewhat more evidently toward the sides, the sides sparsely rugulose; 

 elytra parabolic, a third longer than wide, at the rather tumid humeri just 

 visibly wider than the prothorax, three-fourths longer; striae very fine and 

 subobsolete, represented by series of fine punctures, moderately grooved at 

 apex; pygidium rather larger, semicircular, the deep punctures well sepa- 

 rated; under surface strongly punctured; legs rather short, the anterior 

 not longer in the type and with slender and non-fimbriate tarsi; femora not 

 spiculate beneath; abdomen evenly convex, the first suture fine but distinct 

 throughout. Length 3.8 mm.; width 1.65 mm. Brazil (Santarem). One 

 specimen simplex n. sp. 



The species described above under the name subulirostris, al- 

 though similar to gradatus and the other species in its general 

 habitus, exhibits some very peculiar and aberrant characters relating 

 to the beak and antennae. 



Piperis n. gen. 



The body here is elongate-oval, convex, glabrous, polished and 

 very feebly sculptured, the beak long, rather thick, evenly and 

 strongly arcuate, separated from the head by a rather deep sharp 

 impression, the mandibles bifid, arcuate and decussate. Antennas 

 median, rather short and thick, the first funicular joint longer than 

 the next two, the second one-half longer than wide, 3-7 short, 

 compact and transverse, gradually scarcely wider, the club more 

 than twice as long as wide, gradually pointed and as long as the 

 preceding six joints ; along the sides of the beak beyond the antennae 

 there is a very deep cavernous groove, extending almost to the tip. 

 Prosternum transversely and evenly convex, sparsely punctured 

 and without trace of suture; it is prolonged posteriorly in a long 

 pointed cone, extending behind the posterior mesocoxal tangent and 

 free at apex. Legs simple, rather short; tarsi moderate, with very 

 long fourth joint and strong connate claws, the femora mutic. 

 Prothorax gradually feebly tubulate, the basal lobe gradual, prom- 

 inent and broadly rounded, the scutellum closely fitted, flat, trans- 

 versely sublunate, angulate behind, the elytra with very fine striae, 

 stronger but not coarse at apex, and the pygidium well developed, 

 vertical, rounded, very little wider than long, evenly and strongly 

 convex, finely, sparsely punctate and glabrous. The first ventral
