fusiform-compressed, but not very wide, including the radicle about as 
long as the eyes; pedicel large and pyriform, contracted at apex, much 
thicker than the scape or the following two joints; funicle composed 
of one minute ring-joint which is twice as wide as long; club as long 
as the rest of the antenna, three-jointed, strongly fusiform in shape, the 
basal joint about twice as long as wide at the base but increasing in 
width toward the apex; middle joint about twice as long and thrice

apical joint very strongly conical, nearly as long as the preceding joint, 
and provided with conspicuous longitudinal chitinous ridges running the 
whole length and some of them strongly projecting at apex. Mandi- 
bles with two strong acute teeth at apex. Maxillary palpi apparently one-

Thorax seareely as long as wide; pronotum not visible from above; 
the parapsidal furrows strongly developed, the middle lobe of the
