New Genera and Species of Neotropical Curculioyiidae, 217 



impressed and divided down the middle by a low ridge ; the dorsum 

 with a median furrow that is deepest in front, becoming shallower 

 behind and not reaching the base, the lateral impressions shallow 

 or nearly obsolete; the mandibular scar situated at the end of a 

 long stout triquetrous peduncle which projects 0-7 mm. beyond 

 the apex of the rostrum. Antennae vnih. the scape exceeding the 

 eye and with subrecumbent setae ; 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 base to 

 middle, then narrowed to the apex and wth a shallow apical con- 

 striction; the apical margin truncate above and feebly sinuate 

 beneath; the dorsum with a deep smooth impression forming a 

 furrow in front and widening out behind, there being a large raised 

 triangular area in the middle of the base; the lateral areas very 

 shallowly impressed and almost smooth. Scutellum slightly longer 

 than broad, ovate, bare. Elytra ovate, the basal margui jointly 

 sinuate, the shoulders almost rectangular, the sides gently rounded, 

 and the apices each produced into a long conical process; the 

 longitudinal outline distinctly convex, forming a contmuous curve 

 with the posterior declivity, which has a comparatively gentle slope 

 of about 35° or 40°; the rows of punctures regular but shallow; 

 the sutural area flattened so that interval 3 forms a low costa and 

 with a marked depression at the base, the area between ints. 3 

 and 7 shallowly depressed from the base almost to the middle and 

 bounded behind by a rudimentary transverse costa. Legs slender; 

 the tibiae not denticulate internally, the hind pair not mucronatc; 

 the second joint of the front tarsi a little longer than broad. 

 Length, 15 mm. ; breadth, 5-5 mm. 



Ecuador. 



Described from three specimens, for which I am indebted 

 to M. Albert Bovie, of Brussels. 



Another member of the quadriviltatus group, but readily 

 distinguished by its mandibular processes. 



Exorides caudatus, sp. n. (Plate IV, fig, 1.) 



(j'9. Integument black, not very densely clothed above with pale 

 metallic green scales, often intermingled with whitish scales on the 

 middle of the disk, the scales on the more elevated areas and on 

 the apical processes blue; interval 3 of the elytra more or less bare 

 ( ? abraded) ; the lower surface with similar mingled green and blue 

 scales. 



Head very shiny when the scaling is removed, with very fine
