Brazilian Barin.e 117 



very fine but evident, the others very coarse; femoral punctures strong but 

 sparse, the spicules minute. Length 7.0 mm.; width 4.8 mm. A single 

 specimen, probably from Brazil, received from Desbrochers des Loges. 



tetricus n. sp. 



Form slightly narrower and more sharply rhombic; beak slender, moderately 

 arcuate, three-fourths as long as the elytra, finely, loosely punctate, more 

 strongly toward base, the upper surface just visibly swollen basally; antennae 

 medial, piceous, rather short, with small and slender club, the second funicular 

 as long as the next two combined, the third but little longer than wide; 

 prothorax two-fifths wider than long, the sides subevenly and strongly 

 arcuate, becoming subparallel toward base, the large tubulation with a few 

 minute punctures; basal lobe smooth, very obtuse, the lateral basal im- 

 pressions somewhat deep and conspicuous; transverse scutellum flat, a little 

 wider at apex than at base; elytra as wide as long, nearly a third wider 

 than the prothorax, more narrowly parabolic than in the preceding, the 

 lateral surface but very feebly undulated; grooves deep throughout, 2-4 

 gradually coarser and deeper basally; under surface very sparsely punctulate, 

 the lower part of the thoracic inferior flanks opaque and impunctate; meta- 

 sternum with a deep, narrow and elongate central fossa; femoral punctures 

 strong but sparse, the spicules minute; first abdominal suture obsolete 

 medially. Length 6.0 mm.; width 3.9 mm. Brazil (Chapada). January. 

 A single specimen — probably female adjutor n. sp. 



15 — Abdomen strongly and closely punctured basally; size very small. Obtusely 

 subrhombic; beak slender, evenly cylindric, feebly arcuate, three-fourths as 

 long as the elytra, finely, rather sparsely punctulate, more strongly, irregu- 

 larly so basally; antennae just visibly behind the middle, the club abrupt, 

 as long as the five preceding joints; third funicular joint one-half longer 

 than wide, the second shorter and much thinner than the first; prothorax 

 one-half wider than long, the strongly arcuate sides becoming parallel basally, 

 the subimpunctate tubulation larger than usual, almost half as wide as the 

 base; basal lobe broadly, obtusely rounded, with some rather strong punc- 

 tures; scutellum transversely subquadrate, flat, with some shallow punctures; 

 elytra longer than wide, with converging arcuate sides and moderately 

 obtuse apex, only a fifth wider than the prothorax, the humeri not very 

 prominent laterally but longitudinally callous above; grooves moderate, 

 deep throughout, not dilated at base; under surface with unusually strong 

 punctures, rather close and coarse on the metasternum, but smaller and 

 sparse on the met-episterna; first abdominal suture very distinct; femora 

 with moderately coarse, loose sculpture, the spicules slender. Length 3.8-3.9 

 mm.; width 2.3 mm. Brazil (Chapada — forest). November. Two speci- 

 mens pullatus n. sp. 



Abdomen finely, remotely punctate, the first suture less distinct 16 



16 — Body not very stout, subrhombic; beak slender, cylindric, as long as the 

 elytra, feebly arcuate, minutely, sparsely punctate, a little more strongly 

 toward base; antennae slightly behind the middle, slender, piceous, the first 

 funicular almost as long as the next two combined, the club small, abrupt, 

 rather longer than the three preceding joints; prothorax two-fifths wider 

 than long, the strongly arcuate sides gradually subparallel basally, the large 

 and sparsely punctulate tubulation three-sevenths as wide as the base, the 

 basal lobe slightly punctured, evenly rounded; scutellum transversely sub- 

 quadrate, broadly and feebly concave; elytra slightly elongate, almost a 

 third wider than the prothorax and two-thirds longer, the oblique sides 

 feebly arcuate; apex strongly rounding; humeri prominent; grooves deep 

 and abrupt throughout, subimpunctate, not dilated at base; punctures 

 beneath distinct, sparsest on the abdomen and sternal side-pieces; femoral
