REPORT OF THE STATE ENTOMOLOGIST 351 



Natural enemies The larvae are sakl to be exceptionally free from 

 parasitic attack. There is ai)parenily no record of any true parasite 

 having been reared from this species. Mr Siewers (see citation) records 

 an instance where some confined in empty butter tubs were attacked by 

 house ants, which ate nearly through the epidermis, but without fatal 

 results, though the victims of the attack were covered with black spots. 



An innoxious species. It is only exceptionally that this insect is 

 abundant enough to do any material damage, and in consideration of 

 the slight thinning of die foliage attacked by it, it will seldom, if ever be 

 necessary to resort to spraying with the arsenites or to other means to 

 keep it in check.
