found, they each fasten their tail by a web, and 

 carry a strong thread of the same round their body 

 near the head ; and, thus firmly secured, hang a few 

 hours, when the chrysalis becomes perfectly formed, 

 and divested of the caterpillar's skin. In fourteen 

 days after this the fly is on the wing. The cater- 

 pillars of this latter brood arrive at full growth, and 

 change to chrysalids in September, in which state 

 they remain through the winter till the beginning ot 

 the following May. During this time we often see 

 them hanging under the copings of garden walls, 

 under pales, and in other places where they can 

 have tolerable shelter from the inclemency of the 

 weather. 



The general colour of this Butterfly is white, but 

 the male differs from the female in having: a few 

 dark spots on his wings *. — The most effectual way 

 of clearing the cabbage and cauliflower plants of 

 caterpillars is to send children into the gardens, as 

 soon as they appear in any numbers, to pick them 

 off, and destroy them. This may seem a trouble- 

 some and expensive mode, but it has been found to 

 answer, even to the extent of clearing many acres of 

 field cabbages.
