Extract

In 1930 Dr. R. H. Emslie turned over to the author a small collection of mayfly nymphs collected by him in streams in Scotland. Among them was a small series of nymphs of Ecdyonurus venosus Fabricius in different instars collected at Tummel Bridge and Bridge of Weir. This species is unique in having prominent postero-lateral extensions of the prothorax resembling the wing-pads of the meso- and metathorax (Figs. 1 & 8).
