This bark borer is not without its enemies. I found fully one hall 

 the pupae cases examined, contained nothing but the remains of a para- 

 site that had destroyed the pupa, and had itself failed to escape. The 

 perfect fly was also seen passing over the surface of the bark, seeking a 

 favorable point to make an attack on her victim. Specimens of this fly 

 were sent to Mr. L. O. Howard, Assistant U.S. Entomologist, who pro- 

 nounced it a Chalcid fly belonging to the genus Spaihius.
