New Genera and Sjjecies of Ncotroj)ical Curcidionidae. 215 



produced into a fairly long and very sharp process; the shoulders 

 sharply and rectangularly prominent, the sides being markedly 

 sinuate behind them; the dorsal outline rising from the base, then 

 quite flat to the top of the declivity, which has a slope of 45° ; the 

 dorsum unevenly foveojate, the foveolae in fairly regular rows next 

 the suture and on the inflexed margins, elsewhere quite irregular; 

 interval 3 strongly elevated and sinuous, terminating in an obtuse 

 tubercle at the top of the declivity, and emitting about the middle 

 an oblique carina which reaches interval 7; the setae irregular, 

 short and subrecumbent on the disk, longer and more raised towards 

 the sides and apex; each scale with a central impression. Legs 

 rather slender, with obliqiiely raised pale setae; the tibiae not 

 denticulate internally, the hind pair not mucronate; the second 

 joint of the front tarsi longer than broad. 

 Length, 11-13 mm.; breadth, 4-5-25 mm. 



Venezuela (type). Colombia. 



Described from ten specimens. 



The relatively broad elytra, sharply angulate shoulders 

 and very sharp apical processes give this species quite a 

 distinctive appearance. 



Exorides masoni, sp. n. (Plate IV, fig. 4.) 



$. Integument black, with rather thin, grey or eartli-brown 

 scaling on the dorsvim, intermingled with green scales towards the 

 dorsal margin; on the inflexed margins of the elytra and on the 

 sides of the sternum and abdomen the green scales predominate; 

 the median portion of the lower surface bare. 



Head with very shallow sparse punctation and without any 

 frontal fovea, the ocular margins not impressed and the eyes rathci- 

 less convex than usual. Roslrum about as long as broad, parallel- 

 sided ; the dorsum with a broad triangular impression on the basal 

 half, wth a short longitudinal furrow on each side of it, and the 

 interantennal area absolutely flat. Antennae with the scape exceed- 

 ing the eye, with fine shallow punctures and recumbent pale setae ; 

 the funicular joints in order of length : 2, 1, 3, (4, 5), (6, 7), the apical 

 joints longer than broad, pear-shaped. Prothorax as long as broad, 

 parallel- sided from the base to the middle, then gradually narrowed 

 to the apex, without any apical constriction ; the basal margin 

 strongly rounded, the external angles obtuse; the front margin 

 truncate above and not sinuate beneath ; the dorsum with a broad 

 shallow uneven median impression bounded on each side by a low 

 costa, which is continuous with interval 3 on the elytra ; the external 

 areas very shallowly impressed on the basal half. Scutcllum circular.
