 spiracle of first abdominal segment higher than the others, the tubercle 

 above it absent; three tubercles on mesothorax. First stage single- 

 haired, with tubercles i and ii united. Pupa not seen. Moth with 

 antennae pectinate to tip ; R 2 stalked beyond the origin of R G .

in part) 



Body very stout, especial!}' in male, and woolly ; male antennae with abou^ 

 8 simple joints at apex. Fore wing of male triangular, the outer edge nearly 

 straight, and fully as long as inner; hind wing with apex acute, outer margin 

 strongly concave at middle, and anal angle lobed; wings translucent. Female

 detached before pupation and are woven into the cocoon. A few additional 

 species occur in South America.
