Brazilian Barin^e 131 



finely and sparsely punctate medially, with a very faint and obtuse median 

 stria. Length 5.7 mm.; width 3.65 mm. Brazil (Rio de Janeiro). One 

 specimen — apparently female ruficollis Boh. 



Sides of the prothorax strongly rounding and converging from behind the middle; 

 elytra finely striato-punctate 46 



46 — Body rhombic-oval, black and shining, the prothorax rufous; beak slender, 

 moderately arcuate, cylindric, smooth, roughly sculptured only at the sides 

 basally, not quite as long as the elytra; antennae just behind the middle, 

 slender and rather long, the first funicular joint much shorter than the 

 second, which is nearly as long as the next three, the club small, but little 

 longer than the preceding three joints; prothorax rather less than one-half 

 wider than long, the sides converging from the base, gradually, subevenly 

 rounding to the tubulation; basal lobe strongly rounded, with a narrow deep 

 impressed sinus at the middle of the apex; scutellum subquadrate, strongly 

 transverse and flat; elytra triangular, with broadly arcuate sides and strongly 

 rounded apex, distinctly longer than wide, much wider than the prothorax 

 and three-fourths longer; striae fine and feeble, sometimes slightly impressed 

 and always very distinctly though distantly punctate; abdomen evenly 

 convex, polished, extremely minutely and sparsely punctulate; sexual 

 characters apparently feeble, the prosternal spines wanting in the male. 

 Length 5.9-6.8 mm.; width 3.75-4.2 mm. Brazil (Rio de Janeiro). Five 

 specimens. [ Cryptorhynchus sanguinicollis Germ.] .... sanguinicollis Germ. 



Body smaller and narrower, similar in coloration, subrhombic in form; beak 

 cylindric, smooth, moderately slender and arcuate, slightly thicker and 

 roughly sculptured basally, not as long as the elytra; antennae slightly 

 behind the middle, well developed, piceous, the first funicular joint not as 

 long as the second, which is longer than the next two, the third one-half 

 longer than wide, the club gradually pointed, not quite as long as the pre- 

 ceding four joints; prothorax three-fifths wider than long, nearly as in 

 sanguinicollis throughout, but with the small sinus at the apex of the basal 

 lobe much more minute and inconspicuous; scutellum similar; elytra more 

 distinctly longer than wide, with the oblique sides much less arcuate, the 

 apex more narrowly obtuse and the humeri more narrowly rounded; striae 

 even finer and feebler, but subsimilarly punctulate; under surface finely and 

 remotely punctulate; femora with rather coarse but well separated punctures; 

 abdomen convex and even, very minutely, sparsely punctate — apparently in 

 both sexes, the male without prosternal spines. Length 5.0-6.0 mm.; 

 width 2.8-3.7 mm. Brazil (Rio de Janeiro). November. Four specimens. 



testaceicollis n. sp. 



Body as in the preceding in general form and in coloration, very slightly stouter 

 but much less so than in saguinicollis ; beak longer and more slender, especi- 

 ally toward base, distinctly and evenly arcuate and as long as the elytra, 

 nearly smooth, but coarsely and unevenly sculptured at the sides toward 

 base; antennae distinctly behind the middle, still longer, the first funicular 

 joint longer, though distinctly shorter than the second, which is a little 

 longer than the next two, the third one-half, the fourth a third, longer than 

 wide, the club narrow, gradually pointed, barely longer than the preceding 

 three joints; prothorax nearly as in the two preceding, the impressed sinus 

 in the apex of the basal lobe as distinct as in sanguinicollis and even wider, 

 very much more conspicuous than in testaceicollis, the scutellum very smooth, 

 rather less transverse and more narrowed at base than in either; elytra 

 nearly as in the preceding, more elongate and much less arcuate at the sides 

 than in sanguinicollis, about a fifth longer than wide; striae fine but very 

 distinct, the inner three finely groove-like and less distinctly punctured than 

 those thence to the grooved ninth and tenth, the striae not attaining the
