158 THE ENTOMOLOGIST. 
could very quickly have taken hundreds, had I felt so disposed. 
Iam accustomed to take them very commonly here, but I never 
saw them so abundant as I did in Orkney. Our knowledge of the 
Lepidoptera of these northern isles apparently being so limited, 
I thought it might be interesting to add even so common a 
species as B. quercus to the entomological list of Hoy. -ArTHuR 
Horne; 75, Rosemount Place, Aberdeen, N.B., May 6, 1886. 
IiMYDIA CRIBRUM IN DorsETsHIRE.—In the notes on Lepi- 
doptera in Dorsetshire (Entom. 118), I notice Hmydia eribrum, 
mentioned as “flying on the heath towards dusk.” As this is 
by no means a common insect, it may be of interest if I state that 
with a friend I took this insect freely last year on a Dorsetshire 
heath, but not towards dusk. All our specimens were captured 
in the heat of the day between 11 and 2, and we never once 
saw one later in the day.—Jonn LEA; 1, Claremont ‘Terrace, 
Hampstead, May 20, 1886. 
NyssIA ZONARIA IN LANCASHIRE.—I have captured this year 
many specimens of N, zonaria on an old pasture at Crossens, 
near Southport. The larve (in this district) feed on knapweed 
(Centaurea nigra), not on yarrow, as stated in many works.— 
Ricuarp Cosy; Town Hall, Southport, May, 1886. 
TEPHROSIA CREPUSCULARIA, [Hb., AND T. BIUNDULARIA, Bork. 
—In his notes on these species (Kntom. 98), Mr. Tutt has very 
carefully followed the times of emergence of each in a state of 
nature, and to some extent bases his argument upon them; but, 
in addition to this, a glance at their behaviour in confinement 
may not be without interest, and will, I think, perhaps assist in 
reconciling the very opposite views held by some entomologists 
as to the possibility of distinguishing the one from the other by 
the markings and coloration of the imagines. Tephrosia crepus- 
cularia is the earlier of the two to emerge in the spring, and ova 
are usually deposited by the end of March or the beginning of 
April. The larvee feed up rapidly, and pupate by the end of 
May; a portion of these emerge during the following month, 
and form the summer brood, which is, as a rule, comparatively 
small, both in point of numbers as well as size; but the remainder 
lie over as pup until the following spring, before assuming the 
imago state. These are then among the first to appear, and are
