The larv£e(Fig. 14B) of this genus resemble in habits SciopJiihs. larvse, 

 living in webs on the under surface of the pileus of tree fungi. Before 

 the larvae (which are white and slimy) pupate, they leave this web 

 and spin a silken cocoon, near at hand ; the cocoon is truncate 

 at one end, and, according to Wahlberg,* closed with a lid. 

 This observer also noticed the phosphorescent character of the 

 pupae, which even shine through the silken cocoon. Dufour I figures
