Notes on some Tabanidae (Diptera) from Madagascar, with descriptions of two new species of Aegophagamyia Austen, subgenus Triclida Enderlein.

Sixteen species of Madagascan Tabanidae from 3 recent collections are dealt with. A. (T.) brunnipes sp. nov. and A. (T.) chaineyi sp. nov. are described (both from material collected in montane rainforest near Ranomafana). Chrysops insulensis is redescribed. The genus Picromyza is resurrected from synonymy with Chrysops to hold 4 species: P. infernalis, P. addita comb. nov., P. croceus comb. nov. and P. pauliani comb. nov. (the latter 3 being transferred from the woodi group of Chrysops). Supplemental descriptions are provided for C. aprugnus, C. madagascarensis, P. infernalis and Tabanus silvanus. A. longirostris is illustrated to aid identification, and distributional notes are provided for 8 other species represented in the collections examined: A. pungens, A. brunnea, A. chopardi, A. nebulosa, C. insulensis, Neavella verstraeteni, Tabanocella scirpea, Tabanus obscurestigmatus.
