1 62 Memoirs on the Coleoptera 



Legs pale and bright rufous. Body nearly as in sparsellus in size but decidedly 

 narrower and more elongate; beak short, strongly arcuate, closely squamu- 

 lose and as long as the head and prothorax, the antennae pale rufous; pro- 

 thorax nearly a third wider than long, the sides almost as in sparsellus, the 

 apex relatively somewhat wider, almost three-fifths as wide as the base; 

 basal lobe small, abrupt and rather narrowly rounded; elytra much narrower 

 and more elongate, nearly one-half longer than wide, evenly elongate-oval 

 and fully twice as long as the prothorax, the sides from the small and very 

 feebly prominent humeri longer and more feebly oblique to the base than in 

 the two preceding; sculpture and vestiture nearly similar. Length i. 6-1.65 

 mm.; width 0.65-0.85 mm. Brazil (Entre Rios). Two examples. The 

 female is stouter than the male mansuetus n. sp. 



3 — Form narrow and elongate-oval, moderately shining, black, the legs black, 

 rather short; beak thick, strongly arcuate, closely sculptured and squamulose 

 and as long as the head and prothorax, the antennae rufous; prothorax a 

 third wider than long, the sides moderately converging and subevenly, 

 feebly arcuate throughout; basal lobe small, gradual, short and obtuse; 

 elytra three-sevenths longer than wide, elongate-oval, only very little wider 

 than the prothorax and fully twice as long, the sculpture and vestiture almost 

 as in the preceding species. Length 1. 7-1. 75 mm.; width 0.75-0.8 mm. 

 Brazil (Entre Rios). Three specimens summissus n. sp. 



Form more broadly oval and distinctly larger in size, black, but with the surface 

 lustre faintly aeneous, the legs short, bright rufous; beak thick, shorter and 

 less arcuate than in the preceding and not as long as the head and prothorax, 

 the antennae rufous; prothorax fully two-fifths wider than long, the sides 

 more strongly converging and only very slightly, subevenly arcuate through- 

 out, the apex truncate as usual and four-sevenths as wide as the base, the basal 

 lobe narrower and more prominent, very small; elytra more broadly oval, 

 relatively more strongly rounded at tip, slightly wider than the prothorax 

 and about twice as long, the striae finer than usual, the flat intervals wider and 

 with the loose punctulation rather more confused. Length 1.9 mm.; width 

 0.9 mm. Brazil (Entre Rios). One specimen gravidulus n. sp. 



The species are probably numerous, but seem to be closely allied 

 among themselves. The Entre Rios specimens were all taken in 

 September. 



Starcus n. gen. 



The type of this genus is a very small species of suboval outline 

 and extremely coarse sculpture, having long sparse slender white 

 squamules, arranged in single regular line on each strial interval. 

 The beak is rather slender and strongly sculptured, not separated 

 from the front by an impression, the mandibles prominent, straight 

 within, not at all decussate and when closed form an acute promi- 

 nent angle. The antennae are medial, with rather slender funicle, the 

 basal joint of which is as long as the next three, the others subequal 

 in length among themselves and closely joined, the outer gradually 

 a little wider, the club notably large, elongate-oval, with indistinct 

 sutures and about as long as the entire funicle, somewhat as in 

 the preceding genus. The anterior coxa? are small, separated by 

 very nearly their own width, the prosternum feebly channeled, the
