THE CANADIAN ENTOMOLOGIST. 207 



is too round, and perhaps the example sent for drawing was altered by the 

 alcohol in which it was immersed. The egg really is like that of Comma 

 figured on Plate of Dry as. The number of ribs varies from 8 to lo. 

 Where a string of eggs is laid, the number of ribs is same in all. It is 

 almost needless to say that the young larvae do not consume their egg 

 shells. A lady correspondent says : " The Graptas scramble through their 

 scuttles in headlong haste, totally regardless as to who may take possession 

 'of their late tenements, leaving whole hamlets to prove their presence in 

 the vicinity." The larva attacks the leaf, eating a hole through it, each 

 for itself, and during the first stages feeds about the margin of this hole. 

 During all stages it lives unprotected, except as it lies under the leaf, in 

 contrast with the habit of Cof?ima, which after 2nd moult draws the edges 

 of a leaf together at base and finds concealment beneath the awning thus 

 made.

 of abdominal, short so that the middle of the body is arched a little in 

 walking. After eating the color of the body is pale grayish green. The
