Brazilian Barin^e 445 



finely, sparsely punctulate; prothorax nearly similar, but only a fifth wider 

 than long, similarly sculptured; elytra broadly oval, a fourth longer than 

 wide, proportioned almost as in the preceding, but still somewhat more 

 obtuse behind; striae a little coarser and notably deeper, not evidently 

 punctate, the interstitial punctures similar and subunilinear; pygidium with 

 the transverse angulation less sharply defined; medio-basal abdominal 

 impression of the male nearly similar. Length 3.1 mm.; width 1.6 mm. 

 Brazil (Santarem). One specimen fusiformis n. sp. 



The anterior femora are feebly bent distally, and the tibiae are 

 also very slightly curved. This genus, with the next, seems to 

 stand distinctly alone, and it is not closely allied to the Pseudo- 

 barid series. 



Plasilia n. gen. 



This genus is allied only to the preceding, but the body is shorter, 

 more narrowly rounded behind, strongly convex and evenly oval, 

 glabrous throughout. The legs are short and thicker, but the 

 femora are similarly bent distally. The beak is still shorter, very 

 thick and wide and feebly arcuate, the antennas somewhat similar, 

 but with the club thicker, oval, very abrupt and as long as the 

 preceding six joints, the ashy vestiture erect and bristling, similarly 

 sparser or partially wanting on the basal segment, its distinct 

 sutures dividing it subequally. The prosternal impression is shal- 

 lower and short, the broad and very abbreviated posterior lobe 

 nearly similar, as are the tarsi and tarsal claws. The prothorax is 

 more rounded at the sides and very feebly gradually subtubulate at 

 apex, the basal lobe larger, with relatively smaller, shallow apical 

 sinuation; the scutellum differs in being obtrapezoidal, free and in 

 great part occupied by a shallow opaque impression; the elytra 

 are finely grooved. The pygidium is similarly small and transverse, 

 but is more densely punctate and is feebly, transversely concave in 

 the female, the concavity limited beneath by a feeble transverse 

 ridge. The only known species is the following: 



Plasilia latinasus n. sp. — Very evenly fusiform, convex, glabrous and polished, 

 rufo-testaceous in color throughout; beak ( 9) only about three-fourths as long 

 as the prothorax, which is fully a fourth wider than long, the sides broadly, 

 evenly arcuate to the tubulation, which is much more than half as wide as the 

 base; punctures very sparse throughout, fine, a little stronger near the sides; 

 scutellum free, not closely-fitted as in the preceding genus; elytra a fourth longer 

 than wide, the sides oblique and rather strongly, very evenly arcuate from the 

 more prominent humeri to the narrowly rounded apex; grooves sharply marked, 

 not very deep, about a fifth as wide as the intervals, becoming coarse and exarate 

 at apex, the surface also differing from that of the preceding genus in having the 

 subapical umbones distinct; intervals with remote and subserial, infinitesimal 

 purictules; under surface rather coarsely and conspicuously punctate. Length 

 2.75 mm.; width 1.5 mm. Brazil (Chapada — forest). August. One specimen.
