Brazilian Baring 443 



parallel and feebly arcuate, gradually rounding beyond the middle, the tubulation 

 half as wide as the base (tf) or more ( 9 ); punctures moderately coarse, dense, 

 gradually slightly separated medially, the smooth median line biabbreviated ; 

 elytra fully a fourth longer than wide, barely at all wider than the prothorax, 

 three-fourths longer, the sides parallel and very feebly arcuate, rapidly very 

 broadly obtuse at apex; grooves deep, fully half as wide as the intervals, which 

 are coarsely, closely and uniseriately punctate, with narrow smooth sides; ab- 

 domen strongly, sparsely punctate, the last three segments finely and very densely 

 cribrate, as in some of the Ampeloglypterids. Length 375-3-9 mm.; width 

 1 .8-1 .9 mm. Brazil (Santarem). Two specimens. 



The two examples at hand seem to represent male and female, 

 but there are no special sexual modifications. 



Eugivenius n. gen. 

 The body in this genus is stout, oblong, convex, densely punctate 

 and with fine scattered squamules as in Baris. The beak is rather 

 thick, arcuate, compressed and coarsely, very densely punctate 

 throughout, not separated by a definite sulcus, but with an obtuse 

 impression along the sides beyond the antennas, which are medial 

 and moderate, the first funicular joint as long as the next two, the 

 outer joints compact and more transverse, the club somewhat 

 gradual, thick, oval, about as long as the four preceding joints and 

 very densely, coarsely pubescent. The prosternum has a wide and 

 very feebly concave, not sharply defined longitudinal impression, 

 and separates the coxa by less than half their width, the posterior 

 lobe moderate, not extending to the mesocoxal tangent and feebly, 

 medially sinuate at apex. The prothorax is not tubulate, the basal 

 lobe short and very obtuse and the scutellum is peculiar, being free, 

 twice as wide as long, very densely punctate and rectihnearly 

 parallelogramic, the elytra deeply grooved. The pygidium (o 71 ) is 

 evenly oval, feebly convex and much more than twice as wide as 

 long. Legs moderate, the tibiae notably short, the two posterior 

 pairs very acutely dentate externally near base, and the tarsi are 

 short and broad, the claws closely contiguous for most of their 

 length, thick and smooth. The type is the following: 



Eugivenius cribrosus n. sp.— Oblong, parallel, convex, only feebly shining and 

 dark piceous-brown in color; beak (cf) evenly arcuate, very feebly tapering, 

 fully as long as the head and prothorax and very densely punctate, with a narrow 

 smooth median line above; prothorax convex, a third wider than long, widest 

 behind the middle, the sides arcuate, less so and gradually oblique anteriorly, 

 the apex fully half as wide as the base; punctures coarse, deep and very close 

 but not contiguous, without well defined smooth median line; elytra oblong, 

 parallel and nearly straight at the sides, rapidly very obtuse at apex, between a 

 fourth and third longer than wide, subequal in width to the prothorax and twice 

 as long, the large humeral swellings very faint; grooves a third to fourth as wide 

 as the intervals, feebly catenulate at the bottom, gradually coarser basally but 

 not at apex; intervals very coarsely, densely and confusedly punctate basally
