irregular short recumbent setae. Legs with pale subrecumbent 

 setae; the tibiae not denticulate internally; the second joint of 

 the front ta.rsi longer than broad. 

 Length, 14 mm. ; breadth, G mm. 



Colombia. 



Described from a single specimen. 



Exorides septemcostatus, sp. n. (Plate IV, fig. 3.) 



$. Integument black, with dirty grey scales in the punctures. 



Head with uneven fine punctation and scattered larger punctures ; 

 the fovea small and lying in a shallow depression; the upper and 

 anterior margins of the eyes deeply impressed. Rostrum as long as 

 its basal width, the sides subparallel to the middle and then slightly 

 dilated to the apex; the dorsum with a shallow median furrow 

 (which is very shallowly united with the frontal depression) and a 

 deep oval impression on each side of it; the interantennal space 

 simply depressed ; on each side of the median furrow a longitudinal 

 row of punctures, the rest of the surface more finely and unevenly 

 punctate. Antennae with the scape rather broad and reaching the 

 prothorax, gradually widened to the apex, not squamose but with 

 subrecumbent pale setae ; the joints of the funicle in order of length : 

 (1, 2), 3, 4, (5, 6, 7), the apical joints as long as broad, bead-like. 

 Prothorax broader than long, gently rounded at the sides, widest a 

 little behind the middle, and more narrowed in front than behind ; 

 the apical margin truncate, the gular portion not sinuate; the 

 dorsum with a broad median depression, bounded on each side by 

 a well-marked and finely punctate costa ; the lateral areas narrower 

 than the median one and all of them rugosely foveolate. Elytra 

 ovate, very slightly rounded at the sides, a trifle broader at the 

 middle than at the shoulders, the apices jointly rounded, the 

 shoulders obtusely prominent; the dorsal outline gently convex, 

 the declivity with a slope of about 60°; the shallow striae with 

 large quadrate punctures which are regular throughout ; intervals 1, 

 .3, 5 and 7 regularlj^ and evenly costate and with dense fine punctures ; 

 the setae sparse, short and recumbent, not longer or raised behind. 

 Legs finely and closely punctate, with grey scaling and short sub- 

 erect setae; the tibiae not denticulate, and the hind pair not 

 mucronate ; the second joint of the front tarsi slightly transverse. 



Length, 9 mm. ; breadth, 4 mm. 



Colombia. 



Described from a single female. 



In general form this species much resembles E. lindigi
