ately converging sides feebly arcuate, more rounding and converging in about 

 apical third;' apex less than half as wide as the base; surface with strong, close 

 punctures and slender, loose, evenly distributed pale gray squamules; basal 

 lobe wide but extremely short and broadly arcuate; elytra ogival, with narrowly 

 rounded tip, a fourth longer than wide, a fifth wider than the prothorax and 

 twice as long, the humeri slightly prominent; striae rather coarse and deep, not 

 punctate, the flat intervals with small and asperulate, loosely confused punctures 

 bearing slender squamules, nearly like those of thepronotum; under surface with 

 larger, paler and dense squamules; abdomen in the type with a strong rounded 

 impression at base, which is more finely and sparsely squamulose. Length 2.15 

 mm.; width 1.1 mm. Brazil (Chapada). March. One male specimen. 



The more striking of the peculiarities of this species, are the 

 denticulate femora, large scutellum, slender antennae with elongate 

 funicular joints, and the contiguous anterior coxae. 



Palocopsis n. gen. 



Another minute species, resembling the preceding in some respects 

 but widely isolated structurally, forms the type of this genus. 

 The body is not so rhombic and is more densely clothed with large, 

 parallel, grayish scales. The beak is short, rather thick and feebly 

 arcuate, similarly not separated from the front by any kind of an 

 impression, the mandibles small, dentate and widely decussate, 

 the antennae notably short and inserted near apical third, the club 

 oval, moderate, the first funicular joint as long as the next two or 

 three combined. The prosternum is wholly unimpressed, except 

 by the deep constriction near and parallel to the anterior margin, 

 and the coxae are separated by fully. a third of their width. The 

 femora are scarcely at all inflated and are without vestige of inferior 

 spicule, the third tarsal joint more dilated than in the preceding, 

 and the tarsal claws are rather small and closely connate basally. 

 The prothorax is not apically tubulate and the scutellum is very 

 small, narrow and squamose. The type is the following: 



Palocopsis tecta n. sp. — Rather narrowly oblong-suboval, very evenly and 

 densely clothed with gray scales, which are somewhat smaller, whiter and more 

 evidently separated beneath; blackish in color, the legs and antennae rufous; 

 beak only as long as the prothorax, somewhat strongly and closely punctate 

 throughout and in great part squamulose; prothorax nearly a third wider than 

 long, only very feebly convex when viewed in lateral profile, the sides broadly 

 and distinctly arcuate, a little straighter and more parallel near the base; punc- 

 tures moderate but very close-set and even throughout, without trace of median 

 line; basal lobe very small and narrow, rounded; elytra obtusely oval, scarcely 

 a fourth longer than wide, very little wider than the prothorax and four-fifths 

 longer, obtusely rounded at apex, the humeri scarcely at all prominent; striae 

 rather fine but deep and distinct, the flat intervals with small and close-set, 

 confused punctures; abdomen in the type with smaller, sparser squamules 

 medially at base but not evidently impressed. Length 2.15 mm.; width 1.0 

 mm. Brazil (Chapada). March. One specimen.
