following notice of their locality, &c. from {108} personal
observation, is quoted from a communication to the _Intelligencer_, by a
well-known entomologist, Mr. R. S. Edleston, of Manchester. He says:--

"I and my friend, Mr. Hugh Harrison, in the middle of June made the ascent
to Sty Head Tarn; for the first time in my experience, the weather was
everything we could desire--calm and sunshine; this, combined with the dry
season of last year and the long drought for months during this, enabled us
to collect on ground in other years a dangerous morass. The result was, we
captured _Cassiope_ in abundance, some of them in superb condition, just
emerged from the chrysalis. A very short time on the wing suffices to
injure them. They vary considerably in the development of the black spots
on the fulvous patch, almost obsolete in some through all gradations to the
fullest development; the patch varies in like manner, and also in form;
lastly, they vary in size."

The caterpillar is yet _unknown_.

The _butterfly_ has the wings above of a dark brown colour. Each wing bears
near its extremity a bar of deep but dull red, divided into sections where
the brown veins cross. In each section is usually a black spot, but
sometimes these are absent, and a few red spots take the place of the bar.
The hind wings are smoothly rounded in their outline, and not toothed or
scalloped as in the last species (_Blandina_). The _males_ generally appear
towards the end of June, but a few sometimes earlier. The females, however,
come later. {109} being found in July, and some even as late as August. The
following localities for it are recorded:--Rannoch, Perthshire; Lake
District; Sty Head Tarn; Langdale Pikes; Red Skrees Mountains, near
Ambleside; Gable Hill. But other stations for it will probably be added to
our list in time.

THE MARSH RINGLET, OR SMALL RINGLET BUTTERFLY. (_Coenonympha Davus._)

(Plate VI. fig. 6.)

This species, which is another North-country butterfly, varies so much in
its colouring of sober drab or brown, with black eye-spots, that its
varieties have been described as distinct species under the names of _C.
Polydama_, _Typhon_, and _Iphis_, now, however, all placed together under
the name of _Davus_.

These variations appear to depend in great measure upon local differences
of elevation, latitude, &c.

From this excessive variability also it is very difficult to give a clear
