Brazilian Baring 397 



rapidly rounding and convergent near the apex, which is strongly tubulate; 

 surface with remote infinitesimal punctulation, gradually more distinct later- 

 ally and rugose at the sides, the basal series very distinct and entire; scutel- 

 lum very small, equilatero-triangular; elytra barely longer than wide, para- 

 bolic with feebly tumid humeri, slightly narrower than the prothorax and 

 barely one-half longer; surface less undulate than in any of the preceding, 

 the grooves coarse and deep, finer suturally, the sculpture as defined above; 

 subapical umbones small but prominent; pygidium as usual; under surface 

 very coarsely, densely punctured, the first abdominal segment rather strongly 

 and closely, the others feebly, the first suture obsolete at least medially. 

 Length 2.6s mm.; width 145 mm. Brazil (Santarem). One specimen. 

 & seriatus n. sp. 



10— Body small, cuneate, polished, black, with strong aeneous lustre above, the 

 elytra with a very nearly entire transverse medial, nubilously red fascia; 

 beak rather slender, very evenly cylindric, evenly arcuate, finely, loosely 

 punctulate and as long as the head and prothorax; antennae somewhat 

 beyond basal third; prothorax moderately convex in profile, two-fifths wider 

 than long, the sides parallel and moderately arcuate, rounding rapidly and 

 becoming subtransversely convergent beyond the middle, the strong tubula- 

 tion narrow, only about two-fifths as wide as the base; sculpture and the 

 scutellum nearly as-in the preceding; elytra but slightly longer than wide, 

 parabolic, with slightly tumid humeri, not quite as wide as the prothorax 

 and one-half longer; grooves deep, somewhat crenate, fine suturally, the 

 intervals smooth in about inner, strongly and closely, confusedly punctured 

 in outer, half, except toward apex and on the humeri; scutellum finely, 

 closely punctate, twice as wide as long and circularly rounded; under surface 

 nearly as in the preceding, the punctured first abdominal segment with a 

 very small and feeble medial impression; middle and posterior femora with 

 small simple acute inferior denticle. Length 2.4 mm.; width 1.35 mm. 

 Brazil (Chapada). November. A single male specimen. . . .balteatus n. sp. 



Oblongulus evidently constitutes a distinct subgeneric group, not 

 only in the more elongate first funicular joint, but more especially 

 in the extraordinary first abdominal suture. Because of the long 

 first funicular joint and transverse scutellum, it is probable that the 

 Nicaraguan caseyi Solari, is allied to oblongulus, but the beak is 

 much shorter and the sculpture quite different; caseyi is united with 

 cuneatus Csy., by Mr. Champion, but it bears no close resemblance 

 to that species, differing besides in the scutellum and in antennal 

 structure. Seriatus and balteatus, together with fasaatus Kirsch, 

 also form a very distinctly characterized group of the genus, to 

 which the central Brazilian rufescens and maculatus of Solari may 



also be assigned. 



Paramadarus n. gen. 



A single species of moderately large size and very peculiar appear- 

 ance alone constitutes this genus at present. The body is oblong- 

 suboval, somewhat cuneiform in the male, with vestiture of complex 

 design, and, in profile, the upper surface ascends upward anteriorly 

 from the base of the prothorax. The beak (cT)is long, straight 

 arcuate in about distal half, not separated from the head and with
