 sition begins. The eggs (Fig. 2, a) are not all laid at once, but are 

 deposited in clusters of from three to ten or more, usually being laid side 

 by side in a row. The period of oviposition probably extends Over two 

 weeks or more, as the adults can live seven weeks, though most of them 

 die within a month. One female was dissected; she contained over eighty

 is quite soft and readily flattens upon contact with other eggs, or the leaf 

 upon which it is laid, so that it is usually flattened upon several sides to a 

 greater or less degree. At first the egg is a pearly white, but it gradually 

 turns to a slate colour.

The eggs hatch in about ten days, and the larva begins to feed upon

longer proportionally than in the full grown larva. About a week after
