the prosternum subglabrous, broadly and shallowly concave, and 

 the tarsal claws are rather long and strongly basally connate. 

 The type is as follows: 



Leptogarnia polita n. sp. — Oblong-oval, moderately convex, deep black, smooth 

 and polished', glabrous throughout; beak ( 9 ) fully as long as the elytra, evenly 

 and moderately arcuate, the antennae submedial, moderate, with oval club; 

 prothorax a fifth wider than long, the subparallel sides broadly arcuate, gradually 

 rounding more apically to the strongly tubuliform and truncate apex, the tubu- 

 lation abrupt though with oblique sides, three-sevenths as wide as the base; 

 surface with remote and infinitesimal punctulation, the inferior flanks with coarse 

 and ruguliform sculpture; basal lobe small and rather abrupt, truncate, without 

 lateral impressions; scutellum well developed, quadrate, flat, slightly transverse, 

 clq,se-set at the sides but widely free apically; elytra a fourth longer than wide, 

 only a sixth wider than the prothorax and three-fifths longer, oval, rather strongly 

 rounded at apex, the humeri broadly rounded and scarcely at all prominent; 

 grooves sharply defined, deep, punctulate along the bottom and not very coarse, 

 all attaining the basal edge without dilatation; intervals flat, broadly convex 

 toward the suture, especially basally; under surface moderately and rather loosely 

 punctate, the met-episterna subscabrous; femora slightly inflated, minutely and 

 sparsely punctate. Length 4.4 mm.; width 2.3 mm. Brazil. Deyrolle. 



I received the type of this species from Desbrochers des Loges, 

 under a manuscript name. 



Tenemotes n. gen. 



This and the following genus are distinguished from any others 

 of the Centrinini by having a very acute spiniform tooth on the 

 outer side of each tibia near the base, a character rather common 

 in the Diorymerini. In Tenemotes the body is broadly suboval 

 and convex, glabrous above, except at the thoracic apex, where the 

 scales are interrupted medially, but with conspicuous dense whitish 

 squamules on the basal thoracic lobe and scutellum; each puncture 

 beneath bears a minute and slender squamule, these becoming 

 coarse, dense and conspicuous on the prosternum, which has a 

 moderate concave channel, not sharply defined at the sides, and 

 large, close-set coxae. The beak is nearly straight, densely sculp- 

 tured and micro-squamulose, the antennae medial, with extremely 

 small club, this being smaller than in any other genus to be recalled 

 at present. The mandibles are not decussate, their inner margins 

 slightly denticulate and, when closed, have a rounded outline; the 

 tarsal claws are connate and moderate in size, the femora rather 

 thick but subparallel. The entire upper surface is distinctly punc- 

 tate, and the elytral grooves are very coarse. The abdominal 

 sexual characters are rather conspicuous. There are at hand three 

 species as follows: 



Body oval, convex, deep black and moderately shining; beak nearly straight,
