3 — Form narrower, inflated anteriorly, deep black, polished and smooth, the 

 elytra feebly undulated; beak in the type not so thick as in any of the 

 preceding and longer, distinctly more than half as long as the body, cylindric, 

 evenly and moderately arcuate, not compressed, rather strongly sculptured, 

 longitudinally impressed at the sides basally and sulcate beyond the antennae, 

 which are blackish, median, longer than in the preceding forms and with 

 shorter oval club, this being as long as the four or five preceding joints; 

 prothorax large, scarcely as long as wide, the parallel sides evenly and feebly 

 arcuate, rapidly rounding and oblique in apical third or fourth to the more 

 definite tubulation, which is distinctly more than half as wide as the base; 

 basal lobe moderately prominent, broadly rounded; punctures infinitesimal 

 and remote, forming irregular distant ruguliform but not evidently punctulate 

 lines at the sides; scutellum ogival, wider than long, sinuate at base as usual; 

 elytra nearly one-half longer than wide, the moderately oblique sides feebly 

 arcuate, the apex rapidly rather obtuse, not quite as wide as the prothorax 

 and somewhat less than one-half longer, the humeri and umbones moderate; 

 striae extremely fine but evident and obsoletely impressed, minutely punctate, 

 more impressed but only a little coarser at apex; single loose lines of inter- 

 stitial punctures so infinitesimally minute as to be scarcely discoverable; 

 pygidium vertical, as long as wide, feebly convex and rather sparsely punc- 

 tured, much less strongly or closely than in any of the preceding; abdomen 

 very evenly convex in the type, the prosternum as usual. Length 4.6 mm.; 

 width 1.7 mm. Brazil (Santarem). One specimen subcuneata n. sp. 



It is not practicable to state definitely the sex of any one of the 

 above four unique types, as there are no decisive characters evident 

 beneath, and the pygidium is almost similar in shape throughout. 

 It is certain, however, that no two of them are very closely related 

 specifically. 



Ampeloglypter Lee. 



This genus, like Onychobaris , is of very wide distribution in the 

 western hemisphere and is composed of small to very small, rather 

 elongate, posteriorly very obtuse, glabrous and smooth shining 

 species. The beak is moderate, with bifid decussate mandibles, 

 cylindric and separated by an impression often obsolete in the male 

 but distinct in the female. The antennae are short, submedian, 

 with rather elongate first funicular joint and moderate, narrowly 

 oval club. The prosternum has a large shallow shining excavation, 

 which sometimes takes the form of a rounded fossa, and the generally 

 densely punctate broad posterior lobe approaches very close to the 

 mesocoxal tangent, the anterior coxae separated by their width to 

 one-half more. The legs are rather slender, the femora usually 

 mutic, but sometimes the anterior and middle femora are feebly 

 dentate beneath; the tarsi are narrow, with moderate connate 

 claws. The prothorax is generally tubulate at apex, but not sharply 

 constricted, the basal lobe small, very gradual and broadly rounded 

 or subtruncate, and the scutellum is small, closely fitted and equi-
