In connection with the re-appearance in Ontario of the wheat midge or "red weevil" in fairly large numbers in 1917 and in lesser numbers this year, it is worth while recording that our species is ThecodipJosis mosellana Gehin, and not as we thought, Cecidomyia, or Diplosis, tritici Kirby.

This summer I reared a considerable number of adult midges from larvte collected in 1917 in Welland and Lincoln Counties and submitted them to Dr. E. P. Felt, who, after making a careful exam- ination, sent me the following re- port: "I have decided that the species is with xery little question Thecodiplosis mosellana Gehin.

I am well satisfied that this is not the Cecidomyia, or Diplosis, tritici Kirby unless the characterizations and illustrations of this insect are erroneous, some- thing we are hardly warranted in ; CATOCALA ULALUME STRECK. VS. CATOCALA CAROLINA HOLLAND. BY G. H. FRENCH, CARBONDALE, ILL. In September, 1877, Herman Strecker described Catocala iilalume in his serial, "Lepidoptera Rhopaloceres et Heteroceres," page 132. In the April number of the Bulletin of the Brooklyn Entomological Society for 1880, page 97, Mr. Strecker describes Catocala dejecta. I have taken both of these in this (Jackson) County, 111., and if my memory serves me correctly a specimen of ulahime was submitted to Mr. Strecker for identificat
