Genus Ceroplatus, Box = | 
Fic. 29.—Ceroplatus Lineatus. A. Palpus. 
The larvee (Fig. 148) of this genus resemble in habits Scophi/e larve, 
living in webs on the under surface of the pileus of tree fungi. Before 
the larvee (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 
pupz, which even shine through the silken cocoon. Dufour} figures
