female, where it is smaller and narrower than in the female of latus; abdomen 

 nearly similar. Length 7.7-8.5 mm.; width 3.15-3.45 mm. Brazil (Cha- 

 pada — campo). October and December. Six specimens. .. .chapadae n. sp. 

 3 — Body smaller than in either of the preceding, nearly similar in color, lustre 

 sculpture and general structural characters, the beak (cf) not quite so thick 

 and somewhat more closely punctured, not quite as long as the head and 

 prothorax, the latter almost as long as wide, the moderately converging 

 sides very gradually and only moderately arcuate anteriorly, the tubulation 

 somewhat more abrupt and parallel-sided; sculpture nearly similar; elytra 

 almost as in the two preceding throughout, except that the feebly oblique 

 sides are perhaps somewhat more arcuate; pygidium (d 71 ) nearly as in 

 chapadce, but less transversely semicircular; abdominal impression in this 

 and chapadce much narrower and more acute along the bottom than in latus. 

 Length 7.4 mm.; width 3.28 mm. Brazil (Minas Geraes); Desbrochers des 

 Loges. One specimen reductus n. sp. 



The locality and dimensions of biplagiatas Boh., are not given 

 and, as there are evidently a number of rather closely allied species, 

 it is impossible to select any one of those at hand as being definitely 

 biplagiatus; it is therefore necessary to leave the decision of this 

 point to one having the actual type before him. 



Eudamarus n. gen. 



The body is here smaller and more rhombic than in the preceding, 

 highly polished and almost completely sculptureless above, deep 

 black and with the elytra immaculate. The beak is rather thick, 

 cylindric and feebly arcuate, feebly separated from the front and 

 with stout, bifid and decussate mandibles. Antennae inserted well 

 beyond the middle, with deep scrobes, rapidly becoming inferior, 

 and rather long scape, the first funicular joint somewhat longer 

 than the next three, the outer joints compactly joined, gradually 

 more transverse, the club subevenly oval, as long as the preceding 

 six joints, being relatively much larger than in Madams, and not 

 very evenly divided by the moderate sutures. The prosternum is 

 feebly convex, even and separates the coxae by evidently more than 

 their own width, the posterior lobe, in typical Eudamarus, with its 

 entire base broadly and strongly, evenly and angularly emarginate; 

 but in the subgenus Damarites, it is only very feebly sinuato- 

 truncate. The legs are shining, well developed, the femora normal 

 and mutic throughout in the type, but with the upper margin of 

 the posterior broadly angulate near basal third in vernicatus; the 

 tarsi are rather slender, the third joint larger in impressirostris, 

 notably small in vernicatus, the claws long and strong in the former, 

 shorter in the latter, widely diverging. The prothorax is very 

 gradually and feebly constricted apically, not at all sharply tubu- 

 late, the basal lobe prominent and angulate to broadly rounded, the 

 scutellum in close contact and transversely lunate and the elytra
