68 PLUTELLID^. 



tlioTiglit some new liliglit had fallen upon their crops, but for- 

 tunately subsequent years have not shown a continuance of the 

 inordinate numbers of this species, which was probably checked 

 by a timely increase of its parasitic foes. 



There are only four British species, of which the first three are 

 very similar in markings. ^ ,_
