in the Forest, and of these, three sat on a single trunk. We have never 
seen fagi on the wing, naturally. One, however, that was at rest, was 
startled by being touched on the head, and showed that they can fly; 
it flew very swiftly, almost in a straight line from the place on the 
trunk where it sat, to a point 30 or 40 yards off on the ground, and 
was found only by the sound of its falling amongst the dry leaves. 
The Rev. Bernard Smith considers wet seasons are favourable to the 
moth; in 1860 and 1862, he took more larvge of this species than ever 
before or since. Assembling :—With regard to the habit of assembling, 
Rev. Bernard Smith (“ Notes on the Notos.”) says that a 2 “ taken into 
a wood, and hung up in a cage of muslin, will attract many males 
between 11 p.m. and 1 a.m., on a warm night.” He states, however, 
that “the insect is difficult to pair,” and that “ the second night after 
the 2 has emerged, seems the only favourable one.” The same 
gentleman, in the Ent. Record, i., 67, gives a short account of an 
“assembling” expedition many years ago, when a 2 was taken to an 
elevated spot on the ridge of a hill, and was hung in a muslin cage on 
the branch of an oak about four feet from the ground. The night of the 
expedition was “warm and still,” and at “ about 11 o’clock, a $ came 
flying past the cage, rapidly, and after three or four turns, allowed 
himself to be netted.” About half-a-dozen were taken of some two 
dozen seen. He goes on to say “ One was admitted into the cage, but 
strange to say, immediately became quiet, for this insect is very difficult 
to pair in confinement.” Mr. Holland’s experiences, however, do not 
bear out all these conclusions. His impresssion is, that possibly, 
Mr. Bernard Smith’s strain is weak, from in-and-in breeding, and may 
not perhaps be depended on to act naturally. He writes, “ I have 
always found them pair on the first night, and have had them 
sometimes emerge in the evening and copulate before they were 
quite dry, like Liparis dispar .” I have touched on “ oviposition,” 
when dealing with the ova. Mr. Holland tells me that whenever 
he wanted eggs “ he placed a $ in a good-sized cardboard box, 
where, as soon as it grew dark, she began to fly about and deposit 
eggs here and there about the box.” “ In no case,” he continues, 
“ were all the eggs laid in one night—several nights were needed to 
complete the business.” Of three 2 from which we got ova, one laid 
only eight and then died ; another laid some twenty ; and the remain¬ 
ing one 70 or so; but these two occupied several nights in ovipositing. 
The 2 which laid the 70 did not commence laying until three days 
after capture, and was, when found, in very poor condition. Light :— 
I am indebted to Dr. Buckell for the following records of the occurrence 
of S. fagi at “ light.” I suppose the reason why we get so few records 
of captures at this attraction, is that the usual haunts of the species are 
far from the glare of towns. In Entomologist, 1880 (p. 282), Mr. Pirn 
records the capture of a specimen on a gas-lamp at Dulwich, on 
June 21st, 1880. In the Zoologist for 1843, Mr. J. W. Douglas records 
a specimen on a gas-lamp at Clapham Common, on May 7th, and 
Mr. Edward Doubleday records one on May 10th, at Mr. Low’s Nursery, 
Upper Clapton, but suggests that it was probably brought in the pupal 
state in some moss from Hertford. In the Eiit. Mo. Mag., 1886, 
Mr. J. Hellins (either Exeter or Plymouth) took, on June 28th, a 
wasted A sitting, in the middle of one of the lower panes of a dining¬ 
room window, at 9 a.m. A lamp had been burning in the room till
