ginning of August. Doubtless there is a second brood, 

 which, however, I could not observe. The moths vary much 

 in the sharpness of the markings on the anterior wings, and 

 specimens that are almost of an unicolorous yellowish, or are 

 very faintly marked, are the most plentiful. (1859.) 



BuccuLATRix BoYERELLA, Dup., Heydcn (E. Z. 1863, 

 p. 112). This larva in its entire appearance is rather differ- 

 ent from those of other species of the genus. It gnaws the 

 leaves of the elm at the end of August, and, like the allied 

 species, moults beneath a flat cocoonet. To undergo its 

 change to the pupa state, it constructs, beneath a rather flat, 

 thin, oval, yellowish-grey silken covering, its grey, slightly 

 ribbed, caraway-seed shaped cocoon. The perfect insect 

 appears in the following summer. Around Frankfort, and 

 subsequently also found at Mayence. (1841.)
