Brazilian Baring 345 



sometimes dense, or variegated and conspicuous; they are very 

 numerous in central northern South America, but, as in so many 

 other cases, probably do not occur on the Pacific coast. The beak 

 is rather slender and arcuate, cylindric or feebly tapering and varies 

 from rather short to longer than the elytra; it is not separated by 

 a distinct impression and has the mandibles arcuate, dentate within 

 and decussate. The antennae are medial as a rule, the first funicular 

 joint about as long as the next three, the club well developed, oval, 

 subequally divided by the sutures and as long as the preceding four 

 to six joints. The anterior coxae are usually separated by distinctly 

 more than their own width, the prosternum flat, with small anterior 

 fovea and is generally bispinose in the male, the spines not separated 

 by a circular cavity. The legs are moderate and the tarsi somewhat 

 slender, the claws moderate, arcuate, free and divergent. The 

 prothorax is tubulate to virtually non-tubulate at apex, the basal 

 lobe feeble and truncate or sinuate at apex and the scutellum flat, 

 free, subquadrate, narrowed at base, sinuate at apex and with 

 prominent acute apical angles. The elytra are more or less coarsely, 

 deeply grooved and the pygidium small but always distinct, oblique 

 in the female; the body is nearly always smaller in the female. 

 The numerous species in my collection may be known as follows: 



Elytra broadly fasciate just behind the middle. Body stout, oblong-oval, convex, 

 piceous, the elytra and legs rufous; scales above large, whitish, dense in 

 about lateral fourth of the pronotum, at the elytral base and on the sutural 

 interval to apical third, also scattered toward the sides of the elytra; inter- 

 vals 2-4 densely, 5-6 more sparsely, clothed with yellow-brown scales, from 

 a little before the middle to apical third; under surface densely clothed 

 with whitish scales; beak (d") feebly tapering, rather thin, evenly arcuate, 

 as long as the head and prothorax, punctured and squamulose, the antennae 

 rufous, slender, barely beyond the middle; prothorax subinflated, a fourth 

 wider than long, the strongly arcuate sides parallel basally, the non-tubulate 

 truncate apex three-sevenths as wide as the base; punctures moderately 

 coarse, deep and very close-set, the smooth median line well defined, ex- 

 tending beyond the middle; elytra but very little longer than wide, just 

 visibly wider than the prothorax and only two-fifths longer, oval, individually 

 rounded at apex as usual, the humeri not tumid; grooves deep, punctured, 

 fully a third as wide as the intervals, which are finely, rather closely, con- 

 fusedly punctate in the non-squamose parts, pygidium and propygidium 

 distinct; abdomen scarcely modified; prosternal spines straight, subporrect, 

 very slender, rufous and not quite as long as the prothorax. Length 2.75 

 mm.; width 1.33 mm. Brazil (Chapada). May. One specimen.

Elytra neither fasciate nor densely squamose along the suture, except sometimes
