Some new Coccid-eating Gall Midges (Cecidomyidae)

In 1930 the available information regarding gall midges as enemies of the Coccidae was summarised in a paper published in the Bull. Ent. Res. (21, 1930, pp. 319–329). Since that time there have been several additions to our knowledge concerning such midges. Some of this knowledge was cited as an addendum in a later paper on gall midges as enemies of mites (Bull. Ent. Res. 24, 1933, pp. 215–228). It is proposed in this paper to bring this subject up to date by referring to published work and by describing some new forms that have been received for identification in the immediate past.
