218 . Dr. CUiy A. K. Marshall on 



shallow punctation and a deep round frontal fovea ; the eye margins 

 not impressed. Rostrum rather longer than its basal width and 

 gradually widening towards the apex, sculptured like the head, 

 Avith a very shallow median longitudinal impression and a short 

 oblique one on each side of it; the interantennal area shallowly 

 impressed. Antennae Tvith the scape exceeding the eye, very finely 

 punctate, mth sparse recumbent pubescence and a few erect pale 

 setae; the funicular joints in order of length : 2, ], 3, 4, (5, 6, 7), 

 the apical joints longer than broad and pear-shaped. Prothorax 

 as long as broad, parallel-sided from the base to the middle, thence 

 gradually narrowed and with a distinct apical constriction ; the 

 apical margin truncate above and not sinuate beneath ; the dorsum 

 with three broad longitudinal impressions, the lateral ones shallower 

 and more uneven than the median one. Scutellum circular, with 

 dense narrow scales. Elytra elongate oval, in the (^ sloping from 

 the basal angle to the shoulder and thence gradually narrowed to 

 the apex; in the $, the shoulders nearly rectangular and the sides 

 subparallel to the middle; the base shallowly and jointly sinuate, 

 the apices separately produced into a long stout pointed process, 

 these being rather more divergent in the $ than in the (J; the 

 dorsal outline almost flat, the declivity with a slope of only 35°; 

 the dorsum with large shallow foveolae which are for the most part 

 ill-defined and irregularly confluent; interval 3 costate throughout, 

 and 7 for a short distance in the middle only ; the setae short stout 

 and recumbent, being most numerous between intervals 3 and 7, 

 and becoming finer, longer and more erect at the apex, especially 

 on the processes. Legs slender, densely clothed with blue-black 

 scaling and with scattered green scales, which form denser patches 

 at the base of the femora and on the thickened portion ; the tibiae 

 not denticulate and the hind pair not mucronate ; the second joint 

 of the front tarsi much longer than broad. 

 Length, 13-25-17 mm. ; breadth, 3-6-5-5 mm. 



Colombia : Bogota. 



Described from five specimens. 



Very closely allied to E. quadrivittatus Kirscli, but in 

 addition to the characters given in the key that species 

 differs in having the shoulders of the elytra more rounded 

 and less prominent, and the setae on the disk are much 

 shorter and finer.
