Anacreons ode to the Cicada. 
Happy creature ! what below 
Can more happy be than thou? 
Seated on thy leafy throne, 
Summer weaves thy verdant crown, 
Sipping o'er the pearly lawn 
The fragrant nectar of the dawn. 
Mirthful tales thou love'st to sing, 
Every inch an insect king: 
Thine the treasures of the field, 
All thy own the seasons yield. 
Nature plants for thee the year, 
Songster to the shepherds dear, 
Innocent, of placid fame 
Who of man can boast the same, 
Thine the lavished voice of praise, 
Harbinger of fruitful days. 
Darling of the tuneful nine, 
Phoebus is thy sire devine, 
Phoebus to thy notes has given 
Music from the spheres of heaven. 
Happy most, as first of earth, 
All thy hours are peace and mirth. 
Cares nor pains to thee belong, 
Thou alone are ever young, 
Thine the pure immortal vein, 
Blood nor flesh thy life sustain, 
Rich in spirits, health thy feast, 
Thou'rt a demigod at least.

e above-mentioned species was origin- 
ally described by Dr. Fitch (N. Y. Rep., 847), 
wlio had not seen the winged form, as Byr- 
socrypta ulmicola. The winged individuals 
were first described by the late Prof. Walsh, 
who removed it to li Thelaxes Westw." 
Judging alone from the original description 
of Thelaxes in the " Synopsis of British 
Genera of Insects," it would be almost im- 
possible to say whether this insect is a The- 
laxes or not; but Prof. Wesrwood states in 
his " Arcana Entomologiea." (IL, p. 64) that 
his genus Thelaxes is synonymous with 
Vacuna Kalt. ; and since, in addition to 
other differences, Vacuna has five-jointed 
antennas, it is evident that our insect can not 
belong to that genus, and as I can find no 
generic description which will at all agree 
with this, either in our American authori- 
ties or in Koch, Kal ten bach and Passerini, I 
have presumed it to be new and described 
it accordingly. 
The bibliography of this species really 
seems like a " Comedy of Errors." Dr. 
Fitch placed it in a wrong genus; Mr. 
Walsh removed it to Thelaxes and refers to 
N. Y. Pep., II., 257, instead of IL, 347. "The 
American Entomologist " omits to index it 
for p. 224. Mr. Packard (Guide, p. 525) men- 
tions Thelaxes ulmicola Walsh, while on the 
next page he speaks of Pemphigus ulmicola 
(Fitch), and refers to figure 525, which is 
from an electrotype of the identical wood- 
cut first published by Messrs. Walsh and 
Riley in the "American Entomologist," un- 
der the name of Thelaxes ulmicola Fitch. 
Mr. Packard's figure 525 is, therefore, evi- 
dently my C. ulmicola, and, indeed, I have 
have so far failed to find any other mention 
of & Pemphigus ulmicola Fitch. — [Canadian

The Academy of Science. 
The Academy of Science met at the Poly- 
technic Institute, Monday night, December 
17th. Prof. C. V. Riley, President in the 
chair. 
A very interesting paper on " Migratory 
Butterflies," was read by the President: 
Many quadrupeds that multiply rapidly of- 
ten acquire the migratory propensity. Many 
insects, normally non -migratory, also excep- 
tionally congregate and migrate in vast 
swarms, and this is especially the case with 
butterflies, flights of which, and particularly 
of the yellows (Callydrias and Golias), and 
the whites (Pirns), have been reported from 
Equatorial and South America, and from dif- 
ferent parts of Europe. Vast flocks have also 
been observed at sea. The newspapers in 
the Southwest, and the Signal Officers were 
constantly reporting the passage over Iowa, 
Kansas, Missouri and Texas, of swarms of 
butterflies during the months of September 
and October last. These consisted, in every 
case where determinations were made, of the 
Archippus butterfly (Danais Archippus), 
which is the principal species none to thus 
migrate in North America. 
In an account of the swarming of this but- 
terfly, published in 1870 (Third Mo. Ent. 
Rep., p. 151), I wrote as follows: "It would 
be difficult to give any satisfactory reason 
for this assembling together of such immense 
swarms of butterflies. u Mr. Bates, (Natur- 
alist on the River Amazon, Vol. I, p. 249.) 
gives an interesting account of the uninter- 
rupted procession of butterflies belonging to 
the genus Callydrias, which passed from 
morning to night in a southerly direction, 
across the Amazons, and as far as he could 
ascertain, these migratory hordes were com- 
posed of males." As I have abundantly 
pro\ed by examination of specimens since 
the above was. written,' the individuals com 
posing the swarms of our Archippus butterfly 
comprise both sexes; if anything the females 
prevail. The flights almost always occur in 
the autumn, when the milk- weeds (asclepias) 
upon which the larva of this butterfly feeds, 
have parished. The instinct to propagate is, 
1. iit^-oiY.re, -it the time -in abejfhuce. The but- 
U'iric-5,, unable to supply themselves with 
sweets from flowers, are either altracted in 
quantities to trees that are covered with 
honey-secreting plants, bark-lice, or else 
they must migrate southward, where flowers 
are yet blooming. The Archippus butterfly 
hibernates within hollow trees and other 
sheltured situations. Southerly timber re- 
gions Offer most favorable conditions for such 
hibernation. Under the most favorable con- 
ditions, a large majority perish. A small 
portion of the females survive the winter. 
Such hibernated individuals, upon waking 
from their winter torpor, make at once for 
the prairie, where the milkweeds most 
abound. Faded and often tattered, they 
may be seen flying swiftly over such prairies. 
I have no doubt but that they travel thus for 
many hundred of miles, keepingprincipally to 
the north, and ere they parish, supplying the 
4 milkweeds here and there with eggs. A fresb 
brood is produced in less than a mouth, and 
these extend stiil further north, until we find 
the species late in the growing season as far 
up as the Saskatchewan country, where it 
can scarcely successfully hibernate, and from 
•whence the butterflies instinctively migrate 
southward. We can thus understand how 
there are two, three or more broods in south- 
erly regions, but only one toward British 
America. 
The exceptional flights noticed in the 
spring, and which, so far as recorded, take 
place quite early and in the same southerly 
direction, find a similar explanation. They 
may be looked upon as continuations of the 
autumn flights. Hibernating in the temper- 
ate bekl, they are awakened and aroused up- 
on the advent of spring, to find the milk- 
weeds not yet started; and they instinctively 
pass to more southern regions. There is a 
southward migration late in the growing sea- 
son in congregated masses, and a northward 
dispersion early in the season through isolated 
individuals. It is a notable fact that the two 
butterflies which most display this instinct, 
viz: the species in question and the Painted 
Lady (Cynthia Cardui), have the widest 
range of known species. This last is cosmo- 
politan, occuring in all four quarters of the 
globe, while our Archippus, originally con- 
fined to North America, though ranging from 
Canada to Bolivia, appears to be following 
the milkweeds, wherever these are, through 
chance or purpose introduced. It has lately 
spread over some of the islands of the Pacific 
to Queensland and New Guinea, and over the 
Azores to Europe — such spread necessarily 
indicating great power of long-sustained 
flight. Since the milkweeds are not plants of 
commercial value, anditis highly improbable 
that the species has been carried in any of 
the preparatory states on ships. 
It was suggested by the President that the 
State Signal Service might render itself use- 
ful in noting the migration of birds, animals, 
insects, etc. 
Dr. Engieman presented some engravings 
from an English journal, of a species of fun- 
gus, much like that which attaches itself to 
the potato in Great Britian, which had been 
kept preserved in the rocks thousands and 
thousands of years. The Doctor then made 
some interesting observations on American 
firs, of which, he remarked, there were eight 
or nine kinds here. 
In consequence of some official statements 
by Prof. Cook, of the Michigan Agricultural 
College, the President desired it to go on re- 
cord that he totally disagreed with the pro- 
fessor as to there being any connection be- 
tween phylloxera and the rot on the vine. 
Dr. Englcman agreed with the President 
in this view. 
Report; of tfis Botanist 'Ciiarles H. Peck, 
made to the Regents of tlie University 
of the State of New York. 
Mr. Peck is doing good work for the much 
neglected Fungi. This Report contains a list 
of about eighty species, new to science, and 
two hundred new to the herbarium. It is to 
be hoped that our own state will profit by 
the example of New York. In as much as 
many of our readers may never meet with 
Mr. Peck's Reports we will give a short ac- 
count of his method of preserving Fungi. 
The importance of an Herbarium is so great 
to the working botanist that it seems as if 
many plants are studied or neglected just in 
proportion as they can be dried and pre- 
served. 
The method formerly employed for the 
Fungi, was to place them in bottles of vari- 
ous solutions; but this is very expensive, 
and, besides, takes up too much room. A 
number of receipts for the preservative so- 
lutions are given in the " Linnean Transac- 
tions," Vol. II. p. 263. 
Mr. Lugensdorff proposed the plan of 
boiling the fleshy Fungi in mutton fat and 
thus filling the pores and cells, and then 
covering them with a thin coat of varnish, 
but this is troublesome and a disagreeable 
operation, and not only does not preserve 
the color and form, but causes them to oc- 
cupy a vast deal of space in the cabinet. 
Mr. Peck recommends that the fleshy species 
of Agarici Boleti, etc., should .be dried as 
soon as possible in the full rays of the sun 
t or placed near a stove, care being taken 
that they are not discolored by overheating. 
After being thoroughly dried they may be 
relaxed by being placed in a damp atmos- 
phere, until they are flexible enough to be 
pressed into proper shape to lie well upon 
the herbarium sheets. 
Fungi of a dry and coriaceous texture 
usually need no preparation previous to be- 
ing placed in the plant press. Such speci-
