GRAPTA I. 



in all eggs laid by one female was the same, but Mrs. Peart found that in a string 

 I sent her the topmost egg had eleven ribs, while all the rest had but nine, as 

 shown on the Plate, Fig. a*. The young larvje do not consume their egg shells, 

 as many species do. They eat holes in the leaf, each for itself, and during the 

 first two stages feed about the margins of these. During all stages they are 

 unprotected, except as they lie beneath the leaf. They are not gregarious as a 

 rule, though doubtless where the species is abundant, and the food plant local, 

 their numbers may suggest gi-egariousness. But so many as are hatched on the 

 leaf keep together for two or three stages, then scatter about the plant.
