THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
e. Notodcfnta Dromedarius. — On the 
3rd of August a female came out. On 
the evening of the 5th I exposed her in 
a small leno bag in a locality frequented 
by the insect, keeping her there till half- 
past 10. She fluttered a good deal at 
dusk, but no male was attracted. On 
bringing her home I found a male had 
come out. I turned her in with him ; 
but the morning showed no satisfactory 
result. From that time I kept them 
together till the male died (10th of 
August), and the female was moribund, 
sometimes in a leno bag stretched over 
a birch tree, sometimes in a small box, 
but fruitlessly. The female laid plenty 
of eggs, but they all proved unfertile. 
f. Endromis Versicolora. — On the 24th 
of March, 1859, about 10.30 a. m., I 
found a male and a female drying their 
wings ; another female came out about 
1p.m. I was engaged all day until 
about 10 p. m., when I found the three 
separate. I placed one female with the 
male in a large empty cage, and found 
them separate in the morning : I then 
placed them altogether in the large cage, 
and brought them inside the house. The 
female which had been kept by herself 
since 10 p. m. of the 24th soon began to 
lay, and all her eggs proved fertile. Soon 
afterwards I placed the male on a birch 
twig close to the other female, and a 
quarter of an hour found them in cop. ; 
they separated about dusk, and the eggs 
laid by this female were also fertile. I 
afterwards tried to pair off the male 
with other after-born females, but without 
success. I find the females of this spe- 
cies begin to call about three hours after 
their exclusion. On the 28th I had a 
female out, on the 29th another, and 
on the 31st, about 8.30 a. m., a male ; at 
11.30 a. m. I placed them together: I 
placed them in the sunshine, and caused 
them to flutter about, but without effect. 
At 2.15 I placed the male gently on a 
twig, about an inch from the female of 
the 29th : ten minutes afterwards I found 
the male very comfortably suuggled in 
under the female’s wing: they remained 
in that condition twenty-nine hours — till 
about 7 p. m. of the 1st of April, when 
they separated, and the lady began to 
lay eggs, which of course were fertile. 
Another male came out on the 4th of 
April, and about 1 p. m. he formed a 
matrimonial alliance with a female that 
came out on the 28th or 29th of March : 
about 1 p.m. of the 5th of April they had 
separated, and the female had laid nearly 
all her eggs ; they proved fertile. 
G. Arctia Lubricipeda. — In July, 1859, 
I placed some eight or ten bred speci- 
mens in a small glass breeding-cage, 
and left them there till they all died : 
the glass sides were covered with batches 
of eggs, and I found a male and female 
had died iu each other’s embraces. The 
body of the female appeared quite 
empty : it seems from this that the 
female retains the sexual impulse after 
she has laid all her eggs. 
h. Hadena Atriplicis. — I placed to- 
gether in a glass breeding-cage with 
several pot-herbs, some three or four pairs 
of these insects: if they united I did not 
observe it : a few score of eggs were laid, 
but a friend to whom I gave them told 
me they came to nothing. 
I. Ephyra Orbicularia. — At the be- 
ginning of August, 1860, I bred about 
twenty of these from eggs laid by two 
females taken early in June. I kept 
them together in a large glass cylinder 
placed over sallow twigs standing in wet 
sand, and stood this apparatus in my 
garden among some growing sallows; 
they soon laid me some fertile eggs : 
I did not actually see them in cop.; but
