Chlorops scalaris (Meig.). Frauenfeld (Verh. zool.-bot. ges. in Wien, 
xviii. pp, 896-396) notices an excrescence upon Triticum repens, from which 
he bred this species. He identifies it with that which Giraud supposed to be 
produced on the same plant by Ochthiphila poly stigma (Meig.); the latter 
supposition is probably erroneous.

of this species in troublesome numbers.
