 beak (cf) somewhat longer than the prothorax; antennae medial, the nrst 

 funicular joint one-half longer than wide, the others moderately transverse, 

 not very compact, the club as long as the six preceding joints, the nrst 

 segment about half the length, obconic, with only its extreme base glabrous; 

 prothorax two-fifths wider than long, inflated basally, just visibly narrower 

 at base than at a little beyond, the sides arcuate, oblique and nearly straight 

 in more than apical half; apex nearly three-sevenths as .wide as the base; 

 punctures coarse and unevenly close laterally, less coarse and somewhat 

 widely separated discally, smaller and closer apically and with a very uneven 

 vacant space near lateral fifth; median line broadly impunctate feebly 

 impressed except apically; elytra a third longer than wide, a fourth wider 

 than the prothorax and more than twice as long; surface not undulated but 

 transversely prominent near the apex; coarse punctures well separated and 

 crenulating the intervals, which are convex and finely, sparsely and con- 

 fusedly punctate; male abdomen with a very large shallow basal impression, 

 the fifth segment tumid at the middle of the apex and with minute iguWerous 

 sinus. Length 8.9-10.9 mm.; width 47-5-8 mm. Brazil (Chapada). 



October and January. Three specimens regaus n. sp. 



Body decidedly smaller, more narrowly suboval, black, with dark blue metallic 

 lustre scarcely evident however on the pronotum, except in the teebly 

 impressed smooth median line; beak (cf ) deep black, nearly as in the pre- 

 ceding but somewhat shorter, not quite as long as the prothorax; antennae 

 almost similar, the club very large; prothorax narrower, about a third wider 

 than long, widest at base, less rapidly inflated basally, the sides broadly 

 arcuate, only a little less so anteriorly; apex barely three-sevenths as wide 

 as the base; punctures similar in arrangement but less. coarse throughout; 

 scutellum quadrate, smooth; elytra similar in general outline and sculpture 

 but narrower, even more obtusely rounded behind, the deep reentrant sutural 

 angle similar; strial punctures even more completely coalescent basally; 

 pvgidium tarnsversely oval; male abdominal impression large and shallow, 

 but more acute along the median line, the fifth segment scarcely tumid 

 but with the small deep sinus, bearing a parallel hgula, well defined. Length 

 83 mm.; width 4.35 mm. Brazil (Chapada). November. One specimen. 

 praastans n. sp. 



3-Form rather more oblong-oval, convex; beak ( 9 ) very evenly cylindric and as 

 long as the prothorax, evenly and moderately arcuate, coarsely, closely punc- 

 tate, gradually finely and sparsely so distally ; antennae long and rather slender , 

 piceous, submedial, the first funicular joint elongate, dilated at apex more 

 rufous in color and as long as the next three, the outer joints not dilated, 

 fully as long as wide, the club abrupt, elongate-oval and rather longer than 

 the preceding four joints; scape rather slender, rufous, blackish basally; 

 prothorax a third wider than long, the sides parallel and nearly straight near 

 the base, then broadly rounding, becoming oblique and almost straight in 

 anterior two-thirds; apex only two-fifths as wide as the base; punctures 

 nearly as in regalis in arrangement and size, the smooth median line more 

 dilated centrally and less impressed; scutellum with a few punctures; elytra 

 three-sevenths longer than wide, nearly a fourth wider than the prothorax 

 and much more than twice as long; humeri prominent; sculpture nearly as 

 in regalis, except that the strial punctures are coarser and closer, circular 

 pygidium nearly as long as wide, circularly rounded feebly carmate. Length
