348 Memoirs on the Coleoptera 



denser toward the sides; on the elytra much broader, though linear, confused 

 and rather dense throughout the intervals; beneath large, whiter and very 

 dense throughout; beak in the type rather thick, only feebly tapering, 

 moderately and evenly arcuate, dull, punctulate, squamulose basally and 

 scarcely as long as the head and prothorax, the piceous antennae barely visi- 

 bly beyond the middle; prothorax more than a fourth wider than long, the 

 parallel sides feebly arcuate, gradually rounding beyond the middle, the very 

 briefly and feebly subtubulate apex half as wide as the base; punctures rather 

 coarse and very dense throughout, without trace of smooth median line; 

 elytra very obtusely oval, the sides only just visibly oblique, nearly a fourth 

 longer than wide, distinctly wider than the prothorax and three-fourths 

 longer; grooves coarser than in the preceding, but shallower and not so 

 sharply defined ; intervals coarsely, closely and confusedly punctate; pygid- 

 ium but little wider than long, oblique; abdomen and prosternum wholly 

 unmodified. Length 2.8 mm.; width 1.33 mm. Brazil (Chapada). June. 

 One specimen, of undetermined sex, the beak and antennae indicating the 

 male, the oblique pygidium and absence of abdominal and prosternal modi- 

 fications the female, as shown by the other species vestitus n. sp. 



8 — Prothorax large and finely, sparsely punctured, except toward the sides as in 

 obesulus and suturalis. Stout, shining, rather broadly oval and convex, 

 blackish-piceous, the pronotum laterally and beak distally rufescent, the 

 legs rufous; squamules above yellowish, slender and well separated on the 

 pronotum, wanting in a broad median area; very distinct and in single lines 

 throughout the elytra, but confused toward the scutellum; larger, whiter 

 and dense on the under surface of the hind body, but fine and well separated 

 on the prothorax beneath; beak (<?) rather thick and strongly, evenly 

 arcuate, sculptured and squamulose, as long as the head and prothorax, or 

 ( 9 ) much more slender, smoother, less arcuate and much longer than those 

 parts; antennae submedial ( 9 ), a little beyond (cf), slender, dark rufous; 

 prothorax (cf) fully a fourth wider than long, the parallel sides feebly arcuate, 

 gradually rounding beyond the middle to the feeble tubulation, the punctures 

 small and sparse, larger and roguliform toward the sides, or ( 9 ) not so large 

 and with the punctures medially much stronger, though well separated; 

 elytra oval, only a little longer than wide, very little wider than the prothorax 

 and two-fifths (c? 1 ) to one-half ( 9 ) longer; grooves deep and abrupt, rather 

 more than half as wide as the intervals, which have somewhat strong uni- 

 seriate punctures; male abdomen scarcely impressed but finely, sparsely 

 squamulose medio-basally, the slender testaceous prosternal spines fully as 

 long as the prothorax. Length 2.75-3.2 mm.; width 1. 35-1. 55 mm. Brazil 



(Santarem). Eight specimens ovatus n. sp. 



Prothorax moderate in size and more uniformly punctured 9 



9— Prothorax short, barely more than half as long as the elytra and alutaceous 

 in lustre. Body rather stout, oval, only moderately convex, red-brown in 

 color, the elytra black and slightly shining; yellowish squamules on the 

 pronotum rather large and close basally and toward the sides, more slender 

 apically, elsewhere denuded in the type ; on the elytra they are slender and 

 in single series; whiter and dense beneath; beak ( 9 ) slender, feebly arcuate, 

 much longer than the head and prothorax, rufous, the antennae barely 

 visibly behind the middle; prothorax nearly one-half wider than long, the 

 parallel sides nearly straight, rounding in about apical third; apex distinctly 

 more than half as wide as the base; punctures rather coarse, clearly defined 

 and well separated toward the punctureless median line, gradually coarser 

 and dense laterally; elytra oval, a fifth or sixth longer than wide, evidently 

 wider than the prothorax and more than three-fourths longer; grooves deep
