erect seta, those beneath a little coarser, paler and decumbent, but not con- 

 spicuous; beak distinctly shorter than the prothorax, shining, thick, moderately 

 and loosely punctured and convex at the sides, only very little shorter in the 

 male, but more rapidly tapering; prothorax (c?) smaller, a fourth wider than 

 long, with parallel and slightly arcuate sides, or ( 9 ) a third wider than long, 

 with the parallel sides nearly straight, more rapidly, arcuately converging apically 

 to the tubulation, which is short and much more than half as wide as the base in 

 both sexes; punctures deep but moderate and very sparse, becoming notably 

 coarse and less sparse laterally, and with a broad impunctate median area, not 

 attaining the apex; elytra a fourth longer than wide, very obtusely oval, the 

 arcuate sides but slightly oblique, a fourth wider than the prothorax and some- 

 what more than twice as long; surface slightly sloping downward at base; grooves 

 deep, moderately punctate, about half as wide as the intervals, having the moder- 

 ate and uniseriate punctures widely separated; male abdomen minutely, sparsely 

 punctate, rather coarsely toward the sides, very faintly impressed along the 

 median line basally. Length 2.7-3.25 mm.; width 1. 25-1. 6 mm. Brazil (Cha- 

 pada — forest). November. Eight specimens. 



The flattened form and very short beak in this species would 

 seem to indicate some habitat rather confined as to space. 



Sodesia n. gen. 



In this genus the body is subevenly oval, distinctly convex, with 

 very scanty vestiture, the beak moderately long, slender, smooth 

 and cylindric, separated from the head by the feeblest sort of 

 impression, the mandibles rather small and decussate. The anten- 

 nae are behind the middle, with short scape and somewhat long 

 shaft, the first funicular joint as long as the next three, the three 

 outer joints longer, as well as somewhat thicker than the third or 

 fourth, the club abrupt, oval and but little longer than the three 

 preceding joints, its basal segment constituting half the mass. 

 Prosternum flat, separating the coxae by about their own width, 

 the legs exhibiting nothing abnormal, the anterior femora feebly 

 inflated in typical forms. The basal thoracic lobe is small but 

 distinct and is rather deeply and narrowly emarginate at tip, the 

 elytra sharply but moderately grooved. The three species here 

 assignable are as follows: 



Body oval, rather convex, shining, black, the elytra, under surface and legs 

 slightly piceous; pronotum with slender short sparse erect seta?, which are 

 still more remote, though individually longer, medially, the fine short and 

 erect pale fulvous setae of the elytra in single series; under surface with fine 

 and short, sparse paler setiform squamules; beak evidently longer than the 

 head and prothorax, slender, very smooth, shining, cylindric and finely, 

 sparsely punctulate, becoming somewhat thicker, more closely and strongly 

 sculptured and feebly squamulose basally, evenly and very moderately 

 arcuate; antennae rather behind basal third, rufous; prothorax fully a third 

 wider than long, the feebly converging sides moderately and subevenly 

 arcuate, slightly more so anteriorly to the short subtubulate apex, which is 

 nearly half as wide as the base; punctures rather coarse but shallow and 

 somewhat close-set laterally, becoming remote, smaller and deeper medially,
