234 ELACTITSTIDJE. 



a rather wavy fliglit. Of the oth.er species of the genus we are 

 not aware of more than one brood, though by analogy a hyber- 

 nating autumnal brood is extremely probable; The larva of Tlli- 

 (jcrellHs (according to Fischer's observations in Treitschkc) differs 

 considerably in habit, feeding singlij on JEgojMdiwii Fodagraria 

 l)etvreen several leaves drawn together.
