4. ZETJZEBA Latreille 



Male antennae broadly bipectinate on basal two-fifths, the rest simple. Female 

 antennae simple; vestiture woolly, largely mixed with long spatulate scales and hair; 

 both wings (fig. 295) with stem of M 3 running directly across to the lower side of 

 the cell, making the intercalated cell nearly rectangular. Hind wing with R 2 rudi- 

 mentary, but risible in a well-bleached wing, functionally replaced by a secondary 

 crossvein at end of cell; all veins arising well separated, from end of cell. Frenu- 

 lum strong; palpi rudimentary, hind tibiae with end spurs only. Larva white, 

 cervical shield very large, rough, and black; tubercles black, skin white; last 

 spiracle raised. Larva boring in the twigs the first fall, then moving down to 

 the trunk or larger branches (fig. 295).
