in E. torquatus, are not punctured in £. luridus.

3g @. Black-brown; densely pubescent greyish-white beneath ; pubescence of upperside olivaceous-grey, with 
the head, a triangular mesial area on pronotum from the base forward, and sutural half of each elytron 
greyish-white, the sutural area constricted before middle and again before apex; antenna and legs rufous, 
tip of tibiee and the tarsi more or less black-brown, the latter, however, pubescent-grey ; ninth and tenth 
antennal segments black; sutural and alternate interspaces of elytra with black dots. Rostrum mesially 
impressed at base. Antennal segments 9 and 10 strongly asymmetrical, and more than twice as long as 
apically broad, longer than 11, 10 longer than broad. Pronotum depressed at base, the depression 
gradually disappearing, only vestigial in middle, sides not sinuate before the basal angle, which is 90°, 
with the tip rounded off. LElytra rather strongly impressed at suture, third interspace subcostate, 
especially behind the basal callosity ; fifth and seventh interspaces somewhat convex. 
Prosternum smooth in middle. No punctures on side of mesosternum. Mesosternal process flat, with 
the apex rounded and bent backwards. Abdomen of ¢ a little depressed in the middle, especially 
at base.

Rostrum with a fine mesial carina, generally concealed under the pubescence. Ninth and tenth antennal 
segments nearly symmetrical, the former rather less than half as long again as apically broad, broader 
than long in both sexes, eleventh segment longer than ninth.
