Brazilian Baring 481 



undulations; grooves coarse, deep, a little coarser and subpunctate basally; 

 intervals rather strongly punctate; pygidium small, semicircular, slightly 

 convex and with erect whitish hairs; abdomen (c?) feebly impressed medially 

 at base. Length 2.8 mm.; width 1.5 mm. Brazil (Chapada). March. 

 One specimen balteata n. sp. 



The species named balteata is made the type of a subgeneric 

 group, as above, and it is probable that mendozensis should also be 

 so treated, because of the position of the antennae and brevity of 

 the scape, together with certain habital peculiarities. In balteata 

 the transverse elytral fascia is flexed slightly anteriad toward the 

 suture. 



Trogatia n. gen. 



In this distinct genus the body is parallel and only moderately 

 convex, with minute, sparse and decumbent setae, which are very 

 inconspicuous on the pronotum and under surface and extremely 

 minute in single series on the elytra. Beak short, cylindric, not 

 separated by an evident impression, the antennae slightly beyond 

 the middle, the funicle short, with thick and moderately elongate 

 basal joint, the club very abrupt, oval, entirely pubescent and as 

 long as the five preceding joints, the sutures feeble. Prosternum 

 flat, moderately separating the coxae, with its hind margin feebly 

 angulate at the middle and having, in the male, two minute acute 

 tubercles. Prothorax briefly and narrowly tubulate, the basal lobe 

 very short and broadly rounded, the scutellum small, free, sub- 

 quadrate and with a broad polished canal, the elytra grooved. 

 Pygidium well developed, vertical semicircular, nearly flat and very 

 finely, closely punctate. The legs are normal and slender, the tarsi 

 slender and with slender diverging claws, very moderate in length. 

 The type is the following: 



Trogatia reversa n. sp. — Body perfectly parallel, with straight sides, moderately 

 shining, black throughout, with red elytra and legs; beak feebly arcuate, rather 

 closely punctate, longitudinally bisulcate above and two-thirds as long as the 

 prothorax, the antennae obscure rufous, with ferruginous club; prothorax quad^ 

 rate, about as long as wide, the sides parallel and just visibly arcuate, rapidly 

 rounding in about apical third to the short tubulation, which is barely half as 

 wide as the base; punctures moderate, dense and longitudinally rugose at the 

 sides, separated by between once and twice their widths medially, with a feebly 

 defined smooth median streak centrally; elytra almost a third longer than wide, 

 the parallel sides gradually and feebly rounding from behind the middle, about 

 as wide as the prothorax and two-thirds longer, the humeri small and feeble; 

 grooves not very deep, moderately coarse, finely, catenulately punctate along 

 the bottom, attaining the base but not dilated; intervals not very flat, with 

 single series of moderate, close-set punctures; abdomen very feebly impressed 

 medially at base. Length 3.35 mm.; width 1.3 mm. Brazil (Santarem). One 

 specimen.
