Brazilian Baring 371 



thick, densely punctured, squamulose basally, cariniform above, evenly arcuate 

 and four-fifths as long as the prothorax; antennae piceous; prothorax but little 

 wider than long, the sides parallel and feebly arcuate, rounding and strongly 

 converging in apical two-fifths to the truncate apex, which is much less than half 

 as wide as the base, the dense crust of scales not at all interrupted along the 

 median line; elytra one-half longer than wide, equal in width to the prothorax 

 and three-fifths longer, the sides just visibly converging, gradually more arcuate 

 to the rather obtuse apex, with broad and deep reentrant sutural angle; strise 

 observable as moderate partings of the dense vestiture; propygidium short but 

 distinct; abdomen without evident sexual mark, the first suture very fine and 

 barely traceable, the fourth segment as long as the two preceding. Length 4.5— 

 4.7 mm.; width 1.7 mm. Brazil (Rio de Janeiro). Two male specimens. 



When accidentally denuded the pronotal surface is seen to be 

 subalutaceous, finely and densely punctate; the confused inter- 

 stitial punctures of the elytra are also small. 



Loboderinus Solari 



In this rather isolated genus the body is elongate and cylindric- 

 suboval, somewhat as in the preceding, and the beak is moderate, 

 not very slender and strongly sculptured, especially in the male, 

 separated by a very shallow impression and with acute bifid man- 

 dibles, very prominent when closed, but beyond this there is very 

 little resemblance between the two genera, which differ much in the 

 sexually modified male antennal club and widely separated anterior 

 coxae of Loboderinus, among other features. The body is only 

 partially squamose above, the prothorax non-tubulate and with 

 very small and feeble basal lobe, the scutellum slightly free, variable 

 in form but well developed and the elytra with strong punctured 

 grooves; the pygidium is small, flat, closely punctate and oblique 

 (o 71 ), or subvertical (9). The antennae are medial (9) or at 

 about three-fifths (c?), with long scape, the first funicular joint as 

 long as the next two or three and the club rather large and abrupt, 

 evenly oval ( 9 ), or broad, flattened, very obtuse at tip and with 

 greatly dilated basal segment (d"). The prosternum is even, 

 separating the coxae by distinctly more than their width, not spinose 

 in the male; femora mutic. The three species at hand are the 

 following: 



Pronotum clothed very evenly throughout with slender yellowish squamules, 

 rather widely separated among themselves. Body black, narrow, elongate, 

 subcylindric and convex, the elytra glabrous and shining, the scutellum 

 rather large, wider than long, ogival and densely, pallidly squamose; under 

 surface clothed densely with pale sulphur-yellow scales, the femora with fine 

 slender squamules; legs bright rufous; beak (o 71 ) pale rufous throughout, 

 thick, compressed at the sides, nearly straight, arcuate and feebly tapering 

 distally, finely punctate and as long as the prothorax, which is about a sixth 

 longer than wide, the sides feebly converging and straight, gradually slightly
