The antennae of the male are as broad as the head, and nearly 

 twice as long as broad, sensibly dilated from the base to the 

 apex ; at the middle curved inwards (concave in the inner side, 

 convex on the outer side) ; the antenna of the female are rather 

 shorter, on the internal side almost straight — on the outer side 

 a little curved, towards the apex (for one-third of its length) the 

 sides are parallel ; apex truncate ; prothorax subquadrate, an- 

 terior angles rounded, the sides behind the middle a little con- 

 verging inwardly, a short longitudinal fossula on the middle, 

 not touching either the base or the apex of the thorax.
