Head elongate, depressed, smooth, with two stemmata in the an- 

 terior angles near the base of the antennae. Antenna 4- 

 jointed, the basal joint short and stout ; second elongate, cylin- 

 drical ; third equal to the second in length, growing gradually 

 thicker, but suddenly narrowed towards the apex ; terminal 

 joint slender, elongate, growing gradually thicker to the apex, 

 which is furnished with short bristly hairs, and a small protu-
