 the posterior margin of the antennal groove. The antenna of the 

 male much longer and relatively more slender than that of the 

 female. Labial palpus of five segments, the ultimate one very long, 

 slightly curved, apex produced more posteriorly than anteriorly. 

 Labial palpi extending beyond tip of trochanter I, often nearly to 

 the distal end of femur L 



Thorax : Pronotal comb usually composed of 16 teeth. 

 Legs : As for the genus ; mid- and hind-femora with a medial row
