1 1 is with a feeling of melancholy that 
we read the preface of this volume, and 
then turn to the “ contents.” Certainly, 
for our own part, we are not to be num- 
bered among the “contents,” — we are 
decidedly “ non-content.” 
The present volume of the ‘ Lin ri tea ’ is 
the first which contains no treatise from 
the pen of Professor Zeller. Has the 
sun of the Glogavian Professor set? Still 
in the prime of life and activity, has he 
retired from the labour of instructing 
others? We cannot for a moment be- 
lieve it. 
Look at his magnificent contribution 
to the tenth volume of the ‘ Linntea,’ — 
the genus Bulalis ; that genus, which, 
like many others, seems placed as a sort 
of touch-stone of the human discrimina- 
tory powers, — a species of test-glass, — to 
show how utterly incompetent ordinary 
men are to separate species which they 
know must be distinct. Does that paper 
on Butalis indicate any falling off in the 
powers of the writer? The veriest Gil 
Bias couldn’t pretend to say that it 
“ sent de l’apoplexie.” Wherefore, then, 
are we now to be told that we are to read 
no more from the pen of this illustrious 
writer? Candidly we admit it would not 
be easy for Professor Zeller to have sur- 
passed his last effort, and perhaps he 
thinks, under such circumstances, he may 
advisedly “let well alone.” 
If the sun, after shining so brilliantly 
for ten years, giving a dazzling light 
which has penetrated throughout Ger- 
many, and even to the remotest corners 
of Europe, — for has it not even reached 
Ultima Thule? (a disciple of the great 
Lepidopterist having only last year ran- 
sacked the treasures of Iceland), — must 
withdraw its light; though, we protest, 
once and again, we see no must in the 
case, still, if the genial presence of the 
luminary was to be withdrawn, no more 
worthy substitute could have been found 
than the new star which has appeared in 
the south-west of Europe, on the shores 
of the Lake of Zurich, in the person of 
Professor Frey. 
But, before commencing the considera- 
tion of Professor Frey’s paper on Nepli- 
cula in the volume before us, it may be 
as well to call the attention of some of 
our readers to the last paragraph of the 
preface, from which we find that the valu- 
able treatises that have appeared in the 
first ten volumes of the ‘Linuasa’ are 
now, if a sufficient number of subscribers 
are obtained, to be reprinted, only with 
this difference of arrangement, that the 
papers which treat exclusively of one 
order are to be printed together and sold 
separately from those on the other orders, 
and that thus all the Lepidoptera papers 
can be purchased by those who do not 
trouble themselves about Coleoptera, and 
vice versa. 
As it happens, we know of many per- 
sons who have bought several volumes to 
obtain a series of papers on one particular 
Order, and, probably, there are many 
others who have been thinking of taking 
some similar step, and will now be very 
glad to hear that the Coleoptera , Lepi- 
doptera, & c., papers can be had per se, 
and of course at a proportionate reduction 
of price. 
The contents of the present volume of 
the ‘Linnaea’ are three papers relating 
to Coleoptera. 
One of which, on the Aleocharini, a 
family of the Brachelytra, is from the 
pen of Dr. Kraatz ; who has also com- 
municated a short notice of the Co- 
leoptera found in the nests of the white 
ants, or to speak more technically, of the 
Tennitophilous Coleoptera. 
Dr. Suffrian has a long and very ela- 
borate treatise on the African Cryplo- 
cephala ; and the extensive class of our
