Brazilian Baring 3 8 5 



(d") evenly and moderately arcuate, as long as the elytra, finely but distinctly, 

 sparsely punctate, the antennae dark rufous, or ( 9 ) two-thirds as long as the 

 shorter elytra, more arcuate, the basal half cylindric, more closely punctate than 

 in the male and rather thick, the apical half— beyond the antennae— much thinner, 

 smooth, straight and distinctly flattened, the lateral groove beyond the antennae 

 distinct' for some distance ; prothorax conical, the sides basally and feebly arcuate, 

 evidently longer (cf) or a little shorter ( 9 ) than wide, the infinitesimal punctules 

 very feeble; lobe and scutellum as in the preceding genus; elytra twice as long 

 as wide (<?), two-thirds longer than wide (9), elongate-suboval, barely wider 

 than the prothorax and four-fifths longer; striae as nearly as possible obsolete, 

 deep at apex; male abdomen with a deep elongate impression medio-basally, 

 extending further than in the preceding genus and almost to the apex of the second 

 segment, its slopes with very few remote and extremely minute prostrate hairs. 

 Length 9.3-12.3 mm.; width 3.3-4.0 mm. Brazil (Santarem, Para and Ben- 

 evides). June and July. Fourteen specimens. 



This species differs from the type, named quadriplagiatus by 

 Lacordaire, in its much smaller size and different habitat, that 

 species being an inhabitant of French Guiana — a region evidently 

 separated from the Amazon Valley— and 15 mm. in length, excluding 

 the beak as usual. 



Eutoxus Schon., is another genus allied apparently to Pseudo- 

 madarus and Conoproctus, but there the male prosternum is very 

 broad and armed, and the pygidium is only half free in the male and 

 indistinct in the female. A number of Central American species 

 assigned to Eutoxus by Mr. Champion, probably belong to other 

 genera, undescribed as yet. 



Stripenia n. gen. 



The body in this genus is small, oblong-oval, convex, shining and 

 glabrous above, but densely clothed with large yellowish-white 

 scales throughout beneath. The beak is rather slender, equal, 

 feebly and evenly arcuate, separated by a very feeble impression 

 and with the mandibles dentate within, but only feebly decussate ; 

 they are prominent when closed. Antennae medial, short, the first 

 funicular joint as long as the next three, the second not quite as 

 long as wide, 3-7 very short, transverse, compactly joined and 

 gradually wider to the base of the club, which is very large, ovoidal, 

 thickest beyond the middle, nearly twice as long as the entire shaft, 

 with its basal segment half the length and obconic, with straight 

 sides, and is finely, densely pubescent throughout. The prosternum 

 is flat, separating the coxae by one-half more than their width, and 

 with broadly truncate posterior lobe. The legs are moderate and 

 normal, the prothorax strongly but not abruptly tubulate, with the 

 basal lobe short and broadly truncate, the scutellum wider than 

 long, triangular and punctured and the elytra deeply, evenly 

 grooved, feebly umbonate and with moderately tumid humeri.
