Brazilian Baring 471 



fifth longer than wide, almost a third wider than the prothorax and scarcely 

 twice as long; oblique sides straight, the. apex not very obtuse, with the 

 usual reentrant sutural angle; large oval fovese along the fine striae close-set; 

 irregularly uniserial interstitial punctures coarse, less so and more distant 

 suturally; pygidium very prominent along the median line distally; male 

 abdomen with a large shallow basal impression, the fifth segment with a 

 small apical sinus, having a minute triangular median tooth. Length io.o 

 mm.; width 5.3 mm. Brazil (locality unrecorded). One specimen, from 

 Desbrochers des Loges humerosa n. sp. 



Elytra much longer than wide, with less oblique and faintly subsinuous sides and 

 obtusely rounded apex 3 



3 — Prothorax with the sides strongly, subevenly arcuate, gradually becoming 

 parallel at base, as in the preceding species. Body smaller and narrower, 

 similar in color and general characters, the broad scales of the under surface 

 smaller, sparser and much less conspicuous, each lying wholly within a very 

 coarse puncture; beak (o 71 ) nearly similar in every way, but with a more 

 distinct lateral- impression extending beyond each antenna, the latter black, 

 with slightly narrower club; prothorax not quite so convex in profile, nearly 

 similar in form and sculpture, the very coarse punctures close throughout, 

 not sparser at the sides of the impression; basal lobe differing greatly, being 

 gradually cuspidiform, with narrow and not very broadly rounded apex; 

 scutellum rounded-quadrate, not at all elongate; elytra nearly a third longer 

 than wide, almost a third wider than the prothorax and distinctly more than 

 twice as long; sculpture and also the pygidium almost similar; male abdomen 

 with the large basal impression relatively narrower and much deeper than 

 in the preceding, the fifth segment with shallower sinus and narrower, more 

 isolated minute tooth; female beak just visibly less thick and a trifle longer 

 than in the male, otherwise similar. Length 9.3-9.5 mm.; width 4.8-4.9 

 mm. Brazil (Santarem). Two specimens impressa n. sp. 



Prothorax more parallel, the sides strongly rounding only beyond the middle, 

 tubulate at apex; scales of the under surface each inclosed within a coarse 

 puncture .' 4 



4 — Scutellum quadrate, flat; body rhombic-suboval, shining, with full bronze 

 lustre; beak ( 9 ) slightly shorter than the prothorax, not very thick, cylindric, 

 evenly arcuate, black and minutely, remotely punctulate, becoming coarsely 

 punctate and bronzy at base; antennal club pointed, as long as the three 

 preceding joints; prothorax strongly convex in lateral profile, a third wider 

 than long; punctures extremely coarse and subconfluent laterally, still very 

 large but circular, deep and slightly separated elsewhere, denser apically, 

 without smooth median line; elytra nearly a third longer than wide, almost 

 a third wider than the prothorax and twice as long; surface rugose, the fovese 

 very large, close-set; interstitial punctures very coarse and uneven, smaller, 

 regularly uniserial and very widely spaced on the first two intervals; pygidium 

 with a thin and strongly elevated carina throughout the length; scales of 

 the under surface widely separated but subquadrate and distinct. Length 

 11.0 mm.; width 5.6 mm. Brazil. One female example from Desbrochers 

 des Loges. [Baridius metallicus Boh.] metallica Boh. 



Scutellum elongate, dilated posteriorly, having a large impressed longitudinal 

 canal; body more elongate, similar in coloration and lustre, the beak ( 9) 

 relatively shorter, not over three-fourths as long as the prothorax, otherwise 

 nearly similar; antennal club ovoidal, conically pointed, longer than the 

 three preceding joints; prothorax as in the preceding throughout, except 

 that the tubulation is less abbreviated and in having an elongate smooth 

 spot on the median line just behind the middle; elytra nearly similar but
