Dog's-tail Grass (_Cynosurus cristatus_).

The _butterfly_ appears in June, but is very local--being either found
plentifully in a place or not at all. It has occurred at Barnwell, and
Ashton Wold, Northants; Kettering; Sywell Wood, near Northampton; near
Peterborough; Clapham Park Wood, and Luton, Bedfordshire; Bourne,
Lincolnshire; Monks Wood, Hunts; White Wood; Gamlingay, Cambridgeshire;
Stowmarket; Milton; Rockingham Forest; Dartmoor; Netley Abbey; Charlbury,
near Enstone, Oxon.

THE LULWORTH SKIPPER. (_Pamphila Actaeon._)

(Plate XV. fig. 4, Male; 4 _a_, Female.)

This plainly-coloured little butterfly, prized by collectors for its
rarity, has, in the male sex, great general resemblance to that of the next
species--the common _P. Linea_--but _Actaeon_ may be distinguished by
having the wings clouded over nearly the whole surface with {166} dull
brown, having something of a greenish cast. The _female_ is, however, very
different from that of _Linea_, having all the wings of uniform dingy
brown, excepting a crescent-shaped row of tawny spots near the tip of the
front wing, and a more or less distinct streak of the same colour near the
centre.

The male _Actaeon_ is further distinguished from the female by the
possession of a blackish streak near the centre of his front wing.

_Beneath_, the wings are clouded obscurely with tawny yellow and a dingy
brownish tint, the yellow tinge predominating in the male.

The _caterpillar_ is unknown.

The _butterfly_ appears in July and August, but is so extremely limited in
its local range that it is only to be met with, so far as is known, in
three spots--all on the same line of coast--viz. Lulworth Cove,
Dorsetshire; the "Burning Cliff," about five miles nearer Weymouth along
the coast; and at Sidmouth, Devonshire. At the present time I believe the
"Burning Cliff" is the locality where the insect is found in the greatest
plenty. It is to be looked for on the rough broken ground covered with
weeds that slopes down to the shore on this coast.

Mr. Humphreys states that in 1835 he saw it in great abundance at
Shenstone, near Lichfield.
