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

 the pup^e 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 INIr. L. O. Ploward, Assistant U.S. Entomologist, who pro- 

 nounced it a Chalcid flv belonging to the genus Spathiiis.
