The anterior antennae are not longer than the first 

 body-segment, stout, and scarcely tapering towards 

 the apex, first three joints broader and longer 

 than the rest ; distal half densely clothed with 

 rather long setae, most of which are strongly plumose 

 (fig. 4). Posterior antennae (fig. 5) very stout, 

 3-jointed, longer than the first pair; basal joint very 

 large, about four times as long as the second, and 

 twice as long as the third joint, bearing on its upper 

 surface two hairs, and on the under a 4-jointed 

 secondary branch ; the second joint has 2 strong 

 spine-like setae at the apex, one of which is armed 

 with three long lateral spines near its point, the other 

 being densely clothed with short marginal setae ; the 

 last joint bears four strong curved terminal spines, the 

 two smaller of which are densely fringed with short 

 cilia, the other two with strong divaricate spines ;
