New Genera and Species of Neotropical CurcuUonidae. 211 



tibiae; the tibiae subdenticulate internally, the hind pair not 

 mucronate; the second joint of the front tarsi broader than long. 

 Length, 12-14-75 mm.; breadth, 4-75-6 mm. 



EcuADOE : Macas {Buckley). 



Described from one pair. 



Allied to E. {Coinjjsus) lindigi Kirscli, but in tliat species 

 the rostrum is parallel-sided, the thoracic impression is 

 broader and deeper, the elytra are not costate, and the 

 second joint of the front tarsi is not broader than long. 



Exorides pyriformis, sp. n. (Plate III, fig. 2.) 



$. Integument black; the sides of the rostrum, head, prothorax, 

 elytra (outwards from interval 5), sternum and venter, clothed with 

 pale metallic green scaling; the dorsum of the head prothorax 

 and elytra with grey scales; the femora (except the apex) and the 

 lower surface of the posterior pairs of tibiae green, the rest gvcj. 



Head finely and very closely punctate, with scattered larger 

 punctures, each containing a short recumbent flattened seta; the 

 forehead with a faint transverse dei^ression and a round median 

 fovea ; the eye margins scarcely impressed. Rostrum a little longer 

 than the basal width and somewhat dilated at the apex ; the inter- 

 antennal area broadly and deeply imj^ressed; the dorsum with a 

 broad triangular impression in the anterior half containing a faint 

 median costa, and a short oblique sublateral impression on each 

 side in the basal half ; the sculpture like that of the head. Antennae, 

 vv'itli tlie scape reaching well beyond the eye, with grey scaling and 

 erect pale setae; thp joints of the funicle in order of length : 2, 1, 

 3, (4, 5, 6, 7), the apical joints much longer than broad, clavate. 

 Prothorax subcylindrical, longer than broad, widest at the base and 

 very gradually narrowing anteriorly, the sides almost straiglit ; the 

 gular margin with no trace of sinuation ; the dorsum with the usual 

 three longitudinal impressions, the outer ones being shallower and 

 more rugose than the median, the intervening costae broad and 

 fairly even, with dense minute punctures and a few larger ones. 

 Scutellum cordate, densely squamose. Ehjtra pyriform, broadest 

 far behind the middle, subacuminate behind, with the apices jointly 

 rounded, the basal margins slightly curved, and the line from the 

 external basal to the humeral angle straight and sloping ; the dorsal 

 outline markedly convex, the posterior declivity very steep (80°); 

 the rows of reticulate foveolae fairly regular throughout and trans- 

 versely subconfluent in pairs; interval 3 forming a strong sinuous 

 carina from the base to the top of the declivity, int. 7 much less 

 elevated and twice deeply interrupted near the base; numerous
