THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER.

entomologists Lave made search for the 
eggs or young larvae of the insect, and I 
have now before me two juvenile larvae 
of Assimilella ; thus proving most con- 
clusively that not only is the egg laid, 
but the larva is hatched in the autumn. 
My best thanks are due to Messrs. Healy 
and Killiugback for their exertions to 
clear up this point.

Depeessabia Nanatella. 
The egg of this species is probably 
laid in autumn, as the larvae may be col- 
lected as early as the middle of April, 
when they have already obtained some 
size. The larva mines, or rather bur- 
rows, amongst the hairs on the upper 
surface of the leaves of Carlina vulgaris , 
forming with the silk it spins a complete 
gallery ; the two edges of the leaf being 
also drawn together nearly in a tubular 
form, by this it happens that the whitish 
under sides of the leaves are brought 
into view, which enables the collector 
more readily to discover the hiding-place 
of the larva. The larva grows rather 
slowly, and is not full-fed till near the 
end of June, when it assumes the pupa- 
state, ordinarily without quitting its bur- 
row; several larvae generally occur on 
the same plant. The perfect insect ap- 
pears from the middle of July to the 
beginning of August, but in Italy it 
has occurred as early as the middle of 
May.

POSTAL GUIDE. 
The Post Office now publishes quarterly 
a very useful little shilling volume, 
termed the 1 British Postal Guide.’ We 
regret, however, to find that this work, 
which we belive we consult nearly every 
day, is not so well known to entomolo- 
gists as we could wish. Many defer 
communicating with foreign entomolo- 
gists from day to day and from week to 
week, from some vague feeling of un- 
certainty as to the period of transit which 
the letter or pamphlet would occupy, the 
rate of postage, See. Even with our own 
book post we are continually meeting with 
men of science who are still unaware 
that manuscript, unless it be a “com- 
munication of the nature of a letter,” 
can be conveyed by the cheap regula- 
tions of the inland book post. It 
must, however, be borne in mind that 
this does not equally apply to the 
foreign book post, which, with a single 
exception, is restricted solely to printed. 
matter. 
The facilities now afforded for inter- 
changing our lucubrations with our 
French, Belgian, American and many 
German correspondents, are scarcely used 
one-tenth as much as would be the case 
were they more generally known and 
understood. 
Thus to Belgium and France a packet 
of printed papers under 4 oz. costs only 
3d., under 8 oz. only 6d., under 1 ft. 
only Is. Printed books can also be sent 
to Sardinia and Spain for little over the 
above rates, and to Central Italy ( via 
France and Sardinia) at twice the above 
rates; but no bound books can be sent 
through the post to Spain. Printed 
matter can also be sent at the French 
rales to many parts of Germany, pro- 
vided it is addressed “ via France,” but 
is liable to some additional charge on 
delivery. 
Any pamphlet not weighing more than 
8 oz. may be sent to the United States
