and rotten wood in the cage, of which they very readily availed 
themselves. Some of the larve also spun up on the outside of 
the husks of the nuts. About the middle of June, 1878, the first 
imago made its appearance, and up to the second week in July I 
had not bred more than six specimens. No more appeared 
during the year, which I thought very strange, considering the 
number of cocoons I had. I placed the cage in the garden, 
exposed to the weather, thinking that some would lie in pupa 
until the following year, as many other species do. Some of the 
readers of the ‘Hntomologist’ may remember there were no 
beech nuts in 1878. I visited localities in four different counties, 
but, strange to say, not a single nut could be found. I called the 
attention of some very observant entomological friends to the 
fact, who also never saw any beech fruit. Now, if the insects had 
all appeared, as is usual with many species, the species must have 
become extinct, or found some other food as a substitute, which 
is rather unlikely. In April, 1879, I was thinking of my Grossana, 
and upon opening a cocoon, instead of finding a pupa as I 
expected, I was surprised to find a larva as fresh as though it 
had not been there more than a few days, so I opened another 
with the same result; altogether I opened five, so thought I 
had destroyed enough. In less than two months from that time 
I bred thirty more specimens. ‘There are many Tortrices which 
pass the winter in the larval state, as most of your readers know, 
but I never before knew of this insect remaining so long a larva.

To all corresponding entomologists the need of a special 
directory must often have been felt, and not unfrequently has 
the want of an address been the means of stopping many com- 
munications. Not long since the ‘Entomologist’s Annual’ aimed 
at supplying this want amongst British entomologists. Inter- 
national communications are now more frequent, and let us hope will 
be; the ‘Annual’is no longer published. Dr. Katter has just issued 
Part I. of the ‘Index Entomologicus,’ in which he attempts to 
give the addresses and specialities of all Kuropean entomologists, 
together with a list of entomological societies and periodicals.
