But these Ephemerae, like all other naiads, want working out. The species which Mr. Ronalds gives, are most of them, by his own confession, very uncertain. Of the Phryganidae he seems to know little or nothing, mentioning but two species out of the two hundred which are said to inhabit Britain; and his land flies and beetles are in several cases quite wrongly named.

The Rhyacophiles, on the other hand, are mostly of a shining soot-grey, or almost black.

It kills well when fish are gorged with their morning meal of green drakes; and after the green drake is off, it is almost the only fly at which large trout care to look; a fact not to be wondered at when one considers that nearly two hundred species of English Phryganidae have been already described, and that at least half of them are of the fawn-tint of the caperer.
