culate internal]}', the hind pair iiot mucronate; the second joint 

 of the front tarsi about as long as broad. 

 Length, 16 mm. ; breadth, 8 mm. 



Colombia. 



Described from one female. 



Allied to E. rugosus Tasch., which is however a much 

 narrower insect, with the sides of the elytra not sinuate 

 behind the shoulders and bearing recumbent white setae. 



Exorides abruptecostatus, sp. n. (Plate IV, fig. 7.) 



i^$. Integument black, the elytra with obscure blackish scaling. 



Head with very sparse fine punctures and a large round frontal 

 fovea; the upper margin of the eyes impressed, the anterior one 

 more deej)ly so. Rostrum about as long as its basal width, gradually 

 dilated from base to apex, the sides straight; the dorsum sparsely 

 punctate, with a broad median furrow, which narrowly unites with 

 the frontal fovea, and a shallow stria on each side of it ; the inter- 

 antemial space with a broad shallow curved impression in the usual 

 depressed area. Antennae with the scape not exceeding the eye, 

 clothed only mth sparse pale recumbent setae; the joints of the 

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

 as long as broad, bead-like. Prothorax as long as (9) or a little 

 longer than broad ((J), parallel-sided from the base to three-fourths 

 its length in (J, the sides slightly convergent from the base in 9 ; 

 the dorsal depression very shallow and comparatively narrow, this 

 and the lateral ones very coarsely foveolate, the spaces separating 

 them not carinate, but either smooth or transversely wrinkled and 

 with sparse small punctures; the apical margin truncate above, 

 the gular portion very shallowly sinuate. Elytra oblong-ovate in 

 (J, broader and the sides slightly rounded in $, the apices jointly 

 rounded; the dorsal outline slightly curved from the base to the 

 top of the declivity, which has a slope of about 70° ; the shoulders 

 very obliquely rounded and the sides not sinuate behind them; 

 the shallow striae with regular rows of quadrate punctures, except 

 between striae 5 and 8 behind the middle where the jjunctures are 

 somewhat confused; intervals 3 and 5 raised into smooth costae 

 which terminate rather abruptly at the top of the declivity, intervals 

 7 and 9 carinate for a short distance at the base only ; the intervals 

 with irregular dark recumbent setae, which become longer and 

 suberect towards the apex. Legs piceous, devoid of scaling, with 

 rather large scattered setigerous punctures, the interspaces smooth 

 or coriaceous on the femora and closely and finely punctate on the
