  • 1Dryomyia shawiæ, sp. n., the larvæ of which inhabit the leaves of the New Zealand native shrub Shawia paniculata, is described, and differences noted between this species and the associated midge, Oligotrophus oleariæ Mask., inhabiting, in the larval stages, bud-galls on the same plant.
  • 2A brief account of the bionomics of D. shawiæ is given, and the presence of two Hymenopterous parasites noted.
  • 3A short comparative account follows of the morphology of the larva and pupa and the anatomy of the larva and imago, special attention being given to the points in which D. shawiæ differs from Oligotrophus oleariæ Mask.
