Brazilian Barin^e 4 j 5 



with shining blackish antennae, the outer half of the club paler; prothorax nearly 

 as long as wide, the sides subparallel basally, thence broadly, evenly rounded 

 to the tubulation, the sides of which are oblique; apex not quite half as wide as 

 the base; punctures coarse, very close-set though narrowly separated, with a 

 distinct narrow median smooth line; scutellum glabrous, very feebly impressed; 

 elytra oval, a fifth longer than wide, slightly wider than the prothorax and scarcely 

 one-half longer; surface opaque, feebly impressed along the suture, scarcely at 

 all declivous apically, the grooves a little less than half as wide as the intervals, 

 which are strongly, closely and confusedly punctate, the grooves very gradually 

 less coarse from base to apex; abdomen convex, the first suture obsolete medially, 

 the last three segments largely glabrous along their bases; legs finely, sparsely 

 squamulose. Length 4.3 mm.; width 1.85 mm. Brazil (Santarem). One 

 specimen. 



The sex of the type is probably male, as the pygidium is con- 

 spicuously prominent behind the elytra.

There are few genera more remarkably isolated than this, even 

 in the entire subfamily, the very small straight conical beak and 

 acute thoracic side margins, being its most noteworthy characters. 

 The body is small, convex, oblong and slightly oval, glabrous, rather 

 finely sculptured and convex, the broadly angular thoracic base 

 having medially a small prominent lobe, with its apex narrowly 

 truncate as a rule, the scutellum very small, closely fitted, flat and 

 triangular, the elytra grooved, sometimes shallowly. The pygidium 

 in cuneirostris is peculiar, being large, oblique, rather longer than 

 wide and strongly rounded at tip in the male, without propygidium, 

 but, in the female, it is small, vertical, transverse, convex, less 

 closely but more deeply punctured and separated from the elytra 

 by a very large oblique propygidium. There is but little sexual 

 difference in the beak, which is conical and straight, finely, loosely 

 sculptured and only two or three times as long as wide, the antennae 

 short but rather slender, the scape extremely short, subbasal, the 

 outer funicular joints a little longer and obconical, nearly as in the 

 preceding genus, the club small, broadly oval, about as long as the 

 two preceding joints, with its basal segment smooth, shining, 

 glabrous and slightly more than half the mass; the scrobes are very 

 short, basal and foveiform, prolonged forward slightly by a narrow 

 impression along the sides, the mandibles large, bifid and broadly 

 decussate. The eyes are. large, approximate beneath and rather 

 more coarsely faceted than usual. Prosternum short, broadly, 

 shallowly concave and separating the coxse by about their own 

 width, the posterior lobe broad, flat and truncate, attaining the 

 mesocoxal tangent and with the intercoxal suture obsolete. The 

 legs are very short, the femora mutic, the tarsi very slender, with
