33. APHYCUS BRUNNEUS Howard. 



Aphycus brunneus HOWARD, Bull. No. 5, old ser., U. S. Dept. Agric., Bur. Ent., 

 1885, p. 17. 



The type and only known specimen of this species could not be 

 found. As it was reared from a Diaspine host, Aulacaspis rosae 

 (Bouch6) it can hardly be a true Aphycus and will probably prove 

 to belong to Cocddencyrtus Ashmead. The type locality is Vine- 

 land, New Jersey.
