Brazilian Baring 127 



joint long and cylindric, almost as long as the next three, the second barely 

 longer than wide, the outer joints transverse, the club rather well developed; 

 prothorax two-thirds wider than long, the large tubulation more than three- 

 sevenths as wide as the base, the basal lobe very convex as a part of the 

 discal gibbosity, punctate apically, the rounded apex faintly subsinuate 

 medially, the lateral impressions oblique, distinct; scutellum transverse, 

 subquadrate, well developed and flat; elytra scarcely as long as wide, as 

 usual much wider than the prothorax and three-fourths longer, the oblique 

 sides more arcuate medially, the apex moderately narrow and rounded; 

 humeri only moderately prominent; striae feeble and slightly impressed, the 

 punctures remote but evident, the second with a small deep basal dilatation; 

 abdomen strongly, uniformly convex, minutely and sparsely punctate. 

 Length 4.0 mm.; width 2.7 mm. Brazil (Santarem). One female. 



gibbosus n. sp. 



Inferior flanks with much smaller and sparse punctures; body subrhomboid-oval; 

 beak slender, moderately arcuate, about as long as the elytra, finely, sparsely 

 punctulate, a little more strongly so in the male, especially toward base, the 

 male beak also a little thicker; antennae black, submedial, the first funicular 

 joint scarcely longer than the next two, the second obconic and nearly one- 

 half longer than wide, the club moderately narrow, gradually pointed, longer 

 than the preceding four joints; prothorax three-fifths wider than long, the 

 tubulation two-fifths (cT) or three-sevenths ( 9 ) as wide as the base, the 

 basal lobe margined and with more abundant transverse punctures; scutel- 

 lum nearly similar; elytra slightly (d") or not at all ( 9 ) longer than wide, 

 three-fifths to two-thirds longer than the prothorax, the outline nearly as in 

 gibbosus but with more prominent humeri and more feeble medial arcuation 

 of the oblique sides; strise very fine and feeble, not (9) or broadly (a*) 

 impressed toward the sides, the second feebly dilated at base; male with two 

 slender diverging prosternal spines, visible from above, the first ventral 

 feebly impressed and sparsely punctate medially; female with the abdomen 

 uniformly convex and very finely, sparsely punctate, the first segment very 

 feebly and broadly impressed along the middle. Length 4.8-5.1 mm.; 

 width 3.2-3.3 mm. Brazil (Santarem). Six specimens honestus n. sp. 



37 — Beak rather thick, strongly, longitudinally sculptured, at least in the male, 

 where the prosternal spines are very small and erect, the first abdominal 

 segment flattened and somewhat finely, sparsely punctate 38 



Beak much more slender, smoother and more cylindric in both sexes; prosternal 

 spines of the male similarly very small and erect • • • -39 



38 — Prothorax moderate in size, as usual in this section; form rhombic-oval; 

 beak ( d" ) rather thick, strongly arcuate, almost as long as the elytra, strongly, 

 longitudinally sculptured; antennae black, nearly as in the next species; 

 prothorax a little more than one-half wider than long, the sides slightly 

 converging and moderately arcuate, gradually broadly rounding and much 

 more converging beyond about the middle, the tubulation pronounced, 

 nearly three-sevenths as wide as the base, the basal lobe smooth, with its 

 rounded apex feebly subsinuate medially; lateral impressions strong; scu- 

 tellum well developed, strongly transverse, rather less broad at base than at 

 apex; elytra not as long as wide, parabolic, much wider than the prothorax 

 and three-fourths longer, with distinctly prominent humeri; median part of 

 the sides a little more arcuate; apex not very narrowly rounded; striae 

 very fine and subobsolete, feebly impressed, indistinctly punctate, coarse 

 and grooved apically, second and third slightly dilated and deep basally; 

 under surface sparsely and coarsely punctate, the femora strongly but loosely 

 so. Length 4.2 mm.; width 3.0 mm. Brazil (Espirito Santo). H. Rolle.
