The antennae are scarcely so long as the body in tlie 

 female, and the legs are somewhat shorter. M. Chevrolat, 

 in his " Clytides d'Asie,^' has placed six species in this 

 genus besides the type. For me, so far as I know them, 

 they belong to Demonax. The latter genus he retains, 

 but he has given no reasons for doing so.
