diameters anteriad, gradually and evenly becoming minute and' remote in 

 about basal half; scutellum subsimilar; elytra two and one-half times as 

 long as wide, barely visibly wider than the prothorax and two and a third 

 times as long, the sides parallel and straight, arcuate distad, the apex almost 

 rectilinearly truncate; sculpture nearly as in the preceding; pygidium very 

 oblique, only slightly over twice as wide as long; deeply punctate, less finely 

 and more loosely than in arcuatus; abdomen in the type without trace of 

 longitudinal impression, the fifth segment with a rounded central impression, 

 the hind margin broadly and evenly arcuate. Length 6.4 mm.; width 



1.65 mm. Brazil (Santarem). One specimen lubricus n. sp. 



Body not quite so slender, subcylindric, polished and black, the legs more or less 

 piceous; beak rather thick, evenly cylindric, evenly and feebly arcuate, 

 finely, somewhat sparsely punctate and four-fifths as long as the prothorax; 

 antennae piceous, at three-fifths, the outer funicular joints broader, the club 

 stout, oval, less abrupt, rapidly pointed and about as long as the five pre- 

 ceding joints; prothorax about a sixth longer than wide, evenly conical, the 

 sides scarcely visibly less than straight; apex somewhat over half as wide as 

 the base; punctuation very nearly as in lubricus; scutellum hexagonal, 

 slightly transverse; elytra scarcely two and one-half times as long as wide, 

 very slightly wider than the prothorax and between two and three times as 

 long, the sides just visibly oblique and feebly arcuate, gradually more so 

 toward the truncate apex; sculpture somewhat as in the preceding species; 

 pygidium oblique, rather closely punctate, between two and three times as 

 wide as long and circularly rounded; abdomen strongly, evenly convex, the 

 fifth segment in specimen at hand with a large and shallow rounded central 

 impression, the apex broadly arcuate. Length 6.8 mm.; width 1.85 mm. 

 French Guiana (Cayenne). Desbrochers des Loges. One specimen.

In the last three species the anterior coxae are subcontiguous, but 

 in seriatellus they are distinctly though narrowly separated. My 

 material is so scanty that I am unable to obtain any clear idea of 

 the male sexual modifications of the beak, abdomen and other 

 parts; sometimes, as in arcuatus, these characters however become 

 very evident. 



Strongylotes Schon. 



The body is here more parallel than in Madopterus, with much 

 coarser sculpture, coarsely striate elytra and squamose integuments. 

 The beak is slender, cylindric, nearly straight, being feebly arcuate 

 distally, feebly sculptured, not separated from the head by any 

 kind of impression and short or very moderate in length. Antennae 

 rather slender, medial in insertion, with slender and feebly capitate 

 scape, almost attaining the eye, the first funicular joint as long as 

 the next three and the club oval, pubescent, subequally segmented 

 by the sutures and only as long as the three or four preceding 

 joints. The prosternum is short, almost flat, separating the coxae 

 by scarcely a fourth of their width, truncate behind and with the 

 median line behind the coxae slightly tumid. Prothorax subquad- 

 rate, rapidly rounding at apex, not tubulate and with the basal
