Culjcoides eriodendroni, C. I. & M., outlines of male hypopygii view, a—forceps and harpes; b—aedoeagus. Gold Coast: Nsawam, August and October, 1920; reared from larvae obtained from rot-holes in the stump of a silk-cotton tree and of another tree. Cidicaides grahami, Aust. Several specimens of this species were reared from material taken from the base of a banana stump. The pupal pelt of one female was recovered, and as it was in some respects peculiar and showed several characteristic features, a brief description of it is given. Pupa. Length 16 mm., moderately well chitinised. Respira- tory trumpets long and curved; length about 017mm. Stalk or pedicle moderately long. The trumpets are of almost uniform width throughout their length, and are irregularly ringed. The main tracheal trunk gives off during its course through the trumpet a few short lateral branches which terminate in small tubercles scarcely projecting above the general surface level, and ends distally in a fan-like arrangement of the usual form.
