Length, eight lines. The inferior antennae are rather stout; and 

 the joints of the flagellum are but little longer than half their 

 breadth. The superior antennae are hardly longer than the head, 

 and the flagellum is more than half shorter than the basal portion. 

 The setae or spinules of the legs are more numerous than usual, each 

 set consisting of four to six setules, and those of the upper margin are 

 about as long as those of the lower. The tarsus has a seta just 

 beyond middle of lower margin.
