Brazilian Barinte 119 



Form more broadly rhomboid-oval, the thoracic tubulation relatively much 

 smaller, about a third as wide as the base; prothorax relatively much larger. 



18 



18 — Beak ( 9 ) nearly as long as the elytra, moderately slender, feebly arcuate 

 and rather strongly sculptured, or (d*) very little shorter and more arcuate, 

 somewhat thicker, closely and still more strongly sculptured and somewhat 

 more compressed at base; antennae medial, rufo-piceous, not very elongate, 

 the first funicular joint but little longer than the second, though thicker as 

 usual, the third only slightly elongate and much shorter; club about as long 

 as the four preceding joints; prothorax only a third wider than long, the 

 strongly arcuate sides gradually becoming subparallel through about basal 

 half, the finely punctulate tubulation a fifth the total length; basal lobe 

 nearly smooth, obtusely rounded, feebly impresso-sinuate at the middle of 

 the apex; lateral impressions very feeble; scutellum transverse, truncate, 

 minutely, sparsely punctulate; elytra not longer than wide (9), barely so 

 (o 71 ), three-fifths to two-thirds longer than the prothorax respectively, evenly 

 parabolic in outline, rather obtusely, evenly rounded at apex; humeri 

 rounded, only moderately prominent, not callous above; striae very fine and 

 obsolete, not at all defined, the punctures very small and widely separated, 

 rather evident; striae I, 9 and 10 deep, 2 and 3 slightly dilated and deep 

 basally; under surface sparsely punctulate, the femora with strong and well 

 separated punctures; male with two short curved ante-coxal processes and 

 a small deep well in the posterior part of the deep canal. Length 7.0-7.5 

 mm.; width 4.4-4.7 mm. Brazil (Rio de Janeiro). November. Four 

 specimens gravidulus n. sp. 



Beak (c?) not quite so long, a little thicker and more arcuate than in the male 

 of the preceding species, similarly strongly sculptured; antennae nearly black, 

 not very elongate, the second funicular joint not quite so long as the first 

 and much thinner, the third but little longer than wide, the club narrow, as 

 long as the four preceding joints; prothorax not two-fifths wider than long, 

 the strongly arcuate sides gradually becoming parallel in nearly basal half, 

 the constriction moderately punctate; basal lobe smooth, very gradual, 

 with rather deep lateral impressions, the apex feebly impresso-sinuate at 

 the middle; scutellum transverse, feebly sinuato-truncate, smooth, somewhat 

 convex, a little wider at apex than at base; elytra scarcely as long as wide, 

 much wider than the prothorax and two-thirds longer, parabolic, with 

 somewhat narrowly rounded apex and feebly undulate flanks; striae very 

 fine, feebly punctulate, more groove-like and punctured laterally, the sutural 

 deep as usual, 2 and 3 feebly deepened and subdilated at base; inferior 

 thoracic flanks punctured only toward the coxae; metasternum coarsely 

 striate centrally; male with the first abdominal segment feebly impressed 

 and with close punctures bearing small squamules, the presternum nearly 

 as in gravidulus, but with the rather short and slender spines straighter. 

 Length 7.2 mm.; width 4.8 mm. Brazil (Chapada). December. One 

 specimen grandicollis n. sp. 



Beak (o 71 ) nearly as in gravidulus in form and sculpture, but scarcely so long and 

 just visibly more arcuate; antennae piceo-rufous, somewhat more slender, the 

 funicular joints proportioned almost similarly, but with the seventh smaller, 

 the elongate-oval and pointed club more abrupt, rather longer than the four 

 preceding joints; prothorax large, more transverse, more nearly as wide as 

 the elytra, fully one-half wider than long, the strongly arcuate sides in 

 similar way gradually becoming parallel in nearly basal half; tubulation and 

 basal lobe nearly as in grandicollis; scutellum similar but flatter and narrowed 

 basally — not subparallel as in gravidulus; elytra somewhat narrower than in 

 either of the preceding and slightly longer than wide, more triangular, with
