The-caterpillars of this fly feed on cabbage, or any of the varieties of the cole 

 plants, and are frequently to be met with in gardens. The butterflies make 

 their firft appearance the middle of May. The caterpillars from thefe arrive at 

 their full fize, as at fig. 1, the end of June; when they feek a place adapted for 

 the fecurity of the chryfalis, where they fix themfelves by the tail, and round the 

 middle, with a ftrong web. Thus fecured, the caterpillar flips off its fkin by 

 degrees, and the chryfalis appears as at fig. 2. In fourteen days time after this 

 change, the fly is fporting in the air. This lays its eggs, and in a few days the 

 caterpillars are bred. Thefe caterpillars feed till the end of September, when 

 they change to chryfalides ; in which ftate they remain till May following. This 

 is a very common butterfly, but not more fo than the two fpecies laft defcribed.
