moderate, simple and with slightly inflated femora. The prothorax 

 is tubulate at apex, the basal lobe small and truncate, the scutellum 

 moderate and free and the elytra finely, sharply grooved. The large 

 vertical male pygidium is subquadrate-oval, evenly convex and very 

 finely, densely punctulate. The abdomen (cf) is almost unmodified 

 at base, but the fifth segment has a large deep median cavity. The 

 species are apparently two in number as follows: 



Body subcylindric, polished, glabrous, with polished greenish-brassy lustre; beak 

 fully as long as the head and prothorax in both sexes, the antennae piceous; 

 prothorax a fifth wider than long, the sides parallel and broadly arcuate, 

 gradually broadly rounding beyond about the middle, the tubulation short, 

 half as wide as the base; punctures sparse and very fine, a little more distinct 

 laterally and subrugulose at the extreme sides; scutellum flat, obtriangular, 

 very free; elytra nearly three-fourths longer than wide, parallel, or with 

 very feebly converging and slightly arcuate sides and rapidly obtusely 

 rounded apex, barely at all wider than the prothorax and more than twice as 

 long, the humeri very feebly swollen; intervals flat, with some feeble infini- 

 tesimal punctulation. Length 645-6.8 mm.; width 2.75-2.85 mm. Brazil. 

 Two specimens, without further indication of locality, sent by Desbrochers 

 des Loges. [ 9 Baridias nitidus Gyll.] pyritosus Germ. 



Body throughout almost as in the preceding, but a little less slender and bright 

 pale cupreous in lustre above, black, with seneo-viridate lustre beneath; 

 beak ( 9 ) very little longer than in the preceding and somewhat longer than 

 the head and prothorax, similarly sculptured, the antennae evidently longer; 

 prothorax more elongate, about as long as wide, and with the gradually 

 formed apical tubulation distinctly longer, the sculpture and the scutellum 

 almost similar; elytra of nearly similar form and structure but broader, the, 

 fine grooves posteriorly much more distinctly punctate; pygidium somewhat 

 larger than in the female of pyritosus and with the punctures less minute 

 and less dense, more distinct. Length 7.4 mm.; width 2.95 mm. Brazil 

 (Rio de Janeiro). December cupreolarus n. sp. 



The species described as cupreolatus, from the female alone, is 

 closely allied to pyritosus, but is apparently not the same ; the male 

 would probably settle this point more decisively however. 



Glyptobaris Csy. 



Glyptobaris is a genus of wide geographic distribution, but, like so 

 many others, does not occur in the Pacific coastal regions, nor, in 

 South America, apparently south of the Amazon regions. The 

 body is rather stout, with subcuneiform elytra, and the surfaces 

 above and beneath are very coarsely sculptured, the pronotum 

 densely and uniformly, longitudinally rugose. There seems to be 

 scarcely any sexual disparity, and the sculpture of the under surface 

 sometimes becomes very dense, as in some of the Ampeloglypterids. 

 I cannot identify the two following species with anything hitherto 

 described :
