remote in single lines on the elytra. Beak arcuate above and be- 

 neath, separated by an impressed sulcus. Antennae medial, short, 

 the scrobes extremely oblique, the scape short, not longer than the 

 club, the first funicular joint slightly elongate, the others transverse, 

 compact and gradually increasing, the club as long as the five 

 preceding joints, thick, oval, with its basal segment nearly half the 

 mass, glabrous and shining. The prosternal channel is broad and 

 extremely shallow, although sharply limited at the sides, without 

 trace of foveee at its anterior end, the posterior lobe moderate and 

 feebly sinuate medially at apex; coxae separated by two-thirds 

 their width. The prothorax is not tubulate at apex, the basal lobe 

 broad and gradual, obtusely rounded, the scutellum transverse, 

 somewhat punctate, not impressed and only slightly free, the elytra 

 coarsely, deeply grooved and the pygidium small and semicircular. 

 The legs are moderate and simple, the tarsi slender and the claws 

 closely connate and feebly strigilate. The type is the following: 



Prantisus ovirostris n. sp. — Evenly oval and feebly shining, deep black through- 

 out; beak but little over twice as long as wide and barely more than half as long 

 as the prothorax, evenly oval in lateral profile, finely, not densely, subrugosely 

 punctate, the antennae obscure rufous; prothorax a third wider than long, the 

 sides converging and feebly arcuate, more rounding beyond about the middle; 

 apex less than half as wide as the base; punctures very close but not crowded, 

 very coarse and less coarse intermingled, with a narrow subprominent smooth 

 line abbreviated anteriad; elytra oval, rather more than a fourth longer than 

 wide, a fourth or fifth wider than the prothorax and three-fourths longer; surface 

 sloping slightly to the base throughout the width from the line joining the feeble 

 humeral prominences; grooves coarse, very deep, punctured along the bottom, 

 equal in coarseness throughout the width; intervals not twice as wide as the 

 grooves, with single series of very coarse, rather close-set punctures, the smooth 

 edges in slight relief; under surface very coarsely, closely punctate, the abdomen 

 more finely and loosely, the first suture fine but evident throughout. Length 

 3.5 mm.; width 2.2 mm. Brazil (Santarem). One female specimen. 



The stout oval form, very coarse close sculpture, remarkably 

 short beak and polished glabrous basal segment of the antennal 

 club, will render the identification of. this species very easy. 



Heterosternus Kirsch 



This is the characteristic Brazilian genus of the Pseudobarid 

 series, and it extends well into the Central American region. The 

 species are very numerous and are much smaller on the average 

 than those of Pseudobaris, but are similar in that respect to several 

 of the subgenera of the latter, as previously defined under Craptus; 

 they are oval to cylindric in form and always rather closely and 

 strongly, sometimes extremely densely, punctate. The beak varies 

 from rather short and moderately thick to longer and slender, 

 especially in the female; the antennae are moderate and with oval
