II, Egg-laying. 
This is a title suggesting a good many 
inquiries, e.g . — 
1. How best to induce the insect to 
lay. On this point your ingenious and 
agreeable correspondent “ Q ” has made 
some valuable observations. I should be 
glad to hear from any one who has suc- 
ceeded in getting the lively Hawk-moths 
(such as M. Stellatarum or D. Galii) to 
lay freely. 
2. The numbers of eggs laid by dif- 
ferent species. 
3. The place, mode and time of laying ; 
where, whether by day, dusk or night ; 
how long the process is continued, and 
whether its continuance depends on her 
age at the lime of marriage. 
4. How long the female survives the 
operation. According to my experience 
the process leaves her in a very exhausted 
condition, death soon ensuing. Males, 
on the other hand, seem to retain their 
vivacity after pairing; and so they should, 
if it be generally true that they are ready 
for a second marriage. By-the-bye, is 
this an admitted fact? I do not re- 
member that I have anywhere seen it 
asserted, and had rather inferred the 
contrary, till ray own experience con- 
vinced me that it was at least partially 
true. 
6. The lime of hatching. 
6. The Tnode of fertilization. I believe 
the general impression is that the male 
element is accumulated in a reservoir in 
the female’s abdomen, and fertilizes the 
egg as it is laid. This theory seems 
supported by the facts (so far as my ex- 
perience goes) that where the eggs are 
laid at intervals {e.g. on different nights) 
there are corresponding intervals in the 
hatching, and that eggs e.xtracted by 
the Caesarian operation are infertile. 
The following notes will possibly throw 
light on some of these questions. 
A. B. 
Brighton ; March, 1861. 
A. Arctia Menthastri. The female 
mentioned (Int. ix. 165) began to lay as 
soon as she parted from her mate^_ The 
first night she laid between 300 and 400 
eggs, the next night about 100 more, and 
by the end of the third night she had 
laid more than 600. At dusk of the foL 
lowing day the lady expired. Her eggs 
were scattered in batches of from one to 
fifty over the leno bag ; not one was laid 
on the marigold. The larvae, which 
hatched in about a week, ate the mari- 
gold as readily as mint. 
B. Nolodonta Ziczac. A bred female 
laid me 193 eggs the first night (afier
