The black streak on the clavns will serve to distinguish 

 this species from either of the other two. 



Dr. Power has taken it somewhat commonly on birch, 

 at Birch Wood, in INIay and June ; ]\Ir. Douglas, two or 

 three examples, on fir, in October ; and I have also one 

 from Esher. Messrs. ^^^alker and Haliday also met with 

 it, the latter on the sorrel {Rumex acetosellci). It occurs 

 from May to the end of October.

 lour branches of the arms of the cubitus margined Avith 

 fuscous-broAvn, Avidest at the marginal nerve, and joined
