New Genera and Species of Neotropical Curculionidae. 209 



The very remarkable outgrowth from the tubercles on 

 the elytra looks as though it might possibly be due to a 

 fungus; but Mr. J. Ramsbottom, of the British Museum, 

 lias kindly examined it and reports that the substance of 

 which it is composed is certainly not of fungous origin ; 

 and the same is true of the reddish moss-like filaments 

 that are to be found in the same position in E. wagneri 

 Har. and E. p)raeteritus, sp. n. 



Exorides obesuSj sp. n. (Plate IV, fig. 12.) 



$. Integument black, the upper surface of the thorax and the 

 elytra covered with greenish grey scaling, the elevated ridges being 

 bare ; the head, rostrum, legs, sternum and venter also bare, except 

 for a few scales near the eyes and at the sides of the mesosternum. 



Head with a few very shallow punctures, a large rounded frontal 

 fovea and two smaller ones on the vertex ; the eye- margins impressed 

 in front. Roslrum a little shorter than its basal width, gradually nar- 

 rowed from base to apex, the sides quite straight ; the interantennal 

 area evenly excavated ; the dorsum with a very shallow median im- 

 ]>ression on the anterior half, a shallow longitudinal furrow on each 

 side, and a few sparse punctures. Antennae missing. Prolhorax 

 broader than long, parallel- sided for a short distance from the base, 

 then strongly narrowed, the sides rounded and with a distinct 

 apical constriction ; the gular margin feebly sinuate ; the dorsum 

 with a very deep broad uneven median impression, the adjoining 

 costae and the lateral areas very rugose, the latter shallowly im- 

 pressed near the base. Scutelhim strongly transverse, oblong, very 

 convex longitudinally, and bare. Elytra very broadly ovate, 

 strongly rounded at the sides and broadest at the middle ; the basal 

 margin jointly sinuate, the shoulders very oblique, followed by a 

 small sinuation, the apices jointly rounded; the dorsal outline 

 gently convex, the posterior declivity very steep (80*^); the foveae 

 very irregxilar, shallow, mostly ill-defined, and often transversely 

 confluent, the 9th row (beneath the shoulder) deejily impressed for 

 one-fourth from the base; interval 3 forming a sharp sinuous 

 carina, the flattened sutural area having several fine transverse 

 ridges; the outer dorsal areas shallowly impressed and broken b3' 

 two very ill-defined ridges, the front one a little before the middle 

 and transverse, the other a little behind the middle and oblique; 

 the suture distinctly elevated at the top of the declivity and the 

 posterior callus forming a small tubercle; the setae minute and 

 only discernible with difficulty. Legs with scattered shallow 

 punctures and sparse oblique pale setae ; the tibiae sparsely denti-
