 line between the antenna- are two-median single bristles, and one on each side composed 

 of three rays; projecting from the front of the head are two Hat cnrved spines ending in 

 three digit-like processors (b) ; the clypcus (c) is ai iitcly triangular, the bases are <lrawn 

 down on each side, the lateral serrations nnmerous and small ; just in fnjnt of the eyes is

The thorax bears long ilense lateral iiliunosc tufts, witii smaller short simple tufts in 

 four rows dorsally. 



The first three abdominal segments iicar a tuft of siviial plumose ehietic on each side, 

 the fourth three seta-, and the next three two seta'. The siphon (a) is short and thick, and 



bears two combs of seven long, 

 thick, thorn-like spines; the axial

The impa is 5 mm. long, the

 large and much expanded, one 

 free border being raised into a
