Occasionally the larvae have a tendency to mine within the 

 leaf. ' Usnally they are exposed, but sometimes covered by a 

 slight Aveb. The cocoon is made on the surface of the leaf. It 

 IS not so distinctly of an open network structure as is usual 

 with Plutella, tho there is a tendency for it to be of fine net- 

 work with a thin outer covering. It is denser than usual for 

 Plutella, but thin enough so that the pupa can be made out 

 inside. 



The lot of larvae brought in by Mr. Bridwell, from which 

 the 20 moths wei-e reared, proved to be very highly parasit- 

 ized by Chelonus hlacl-hurni. Thirty-three of this parasite 

 issued from the lot, making a parasitism of 62%.
