lature, like Virgil's sorceress, incessantly repeats,
enchanting: Duvitc, ah urhc dnnmrn. men cnr»nna, durifc
Daphuim! and brings us by many lures to her home in
wood and field. Under the spell exercised by the display
of Butterflies and Moths, we may behold the Entomologists,
chasing their treasures by day through the meadows, in the
evening waiting for them by beds of scented flowers, at
ni'ght watching by bait and light the coming of their tiny
prey. The study combines Art and Science in a peculiarly
seductive manner. Even in flowers we have no more
beautiful patterns and colors and here these may be preserved
for the most part perfectly and for a life time in a Collection.
Tints which we do not find in Art often brought together,
are here harmoniously blended, as the blue and green in
the Wandering Hawk Moth, Argons hibnisccw, and the pink
and yellow of the Eosy Dryocampa. The moths afford
superb instances of the blending of neutral tints, unspeakably
soft broAvns and grays, as in the Smrrinthinae and the
"False Hawk Moths", the species of the Bombycid genus
Apatehdes. These two, A. aru/flica and A. fonrfacta, are
remarkable for their casual resemblance to certain un-
ocellated Smcrhdhinac, no less than for the delicacy of
their shaded neutral colors. It is owing to the natural
constitution of the human mind, that it is pleasantly occupied
in observing the diiferent forms, in solving the many questions

6

which the structure and lives of these tiny creatures suggest.
In the case of the Indo-Germanic peoples there is, to aid
this, a decided tendency to the study of Natural History,
to investigate the material constitution of the world in Avhich
we live and of which we form a part.

Collecting with the net over flowers in the evening,
when the Hawk Moths are active, is a very alluring pursuit.
Verbena beds, Avhere the flowers are of the white variety,
against which the hovering j\Ioths art; more easily seen,
I have found very productive. An intelligent and charming
writer, Mrs. C. H. Fernald, has given us a list of the
cultivated plants attractive to these insects. I may be
forgiven for ([uoting her words: ..Most people love flowers
and cultivate them for their beauty and fragi-ance, but to
collectors of insects some of them have a double charm,
for they attract some of the most beautiful and rare
Lcpidopfrfd. The common lilac, Si/rii/f/a rulffaris and the
Tartarian and Sil)erian Honeysuckles, when in full bloom,
during the hottest hours of a bright, sunny day, are a
perfect paradise for several of the Lei)idoptera, as Avell as
numerous Hymenoptera and I)ii)tera. The gaudy I'djnUo
tiiruHs sails proudly over the highly scented flowers, fre(iuently
dropping down to sip the nectar: and Hcmori.^ diffiuis and
ihiisbo, with an occasional <fr(iri/ls, whiz about the flowers
as "busy as the bees." Tlien, at twilight, the larger Sphinx
moths, (/(irdi/is and cliiniKiciiciii, and i-arely /Nscifiosa. dart
swiilly from shrub to shrub, and from flower to floAver,
requiring a ([uick eye and hand to capture them, /fcliojtliila
alhiUiH'a, P/usid si m pier, and jn-crdfioiiis, and occasionally
a hiniac/ildfd are also taken on these flowers. I have
captured more insects o]i Ocudthcra LaiiHirc/ciaiut, than on
any other plant. A plot about three feet square gives from
fifty to one hundred fresh flowers about four inches in
diameter ever}- evening, and if the seed pods are picked
off, they may be kept in bloom for three months." In addition
to the Omothcra, or Evening Primrose, of which Mrs. Fernald
writes, my kind friend Mr. L. W. Goodell of Amherst, Mass. ,
notes the cultivated varieties of Datura, Mignonette, Alyssum,

and Pinks as being very attractive to Motlis. On Staton
Island, where the wild Ddho-a flninifniiin)/, or Janu'stown
Weed, is common, T have tak(;n several Hawk ]\I()ths on its
white and pnrple llowers. Also on different sorts of Axvlcpias,
or Milkweeds, the leaves of which are eaten by the larvae
of DniifiKft ph'xi})})Hs and FjkIkh'Ics ciiIc, and are gi^nerally
very attractive jilants to bees and beetles and buttcMflies.

In taking Cloths with the net, the poison buttle should
be kept handy and the insect introduced into it as (piickly
and dextrously as i)ossible, to prevent injury to the wings
and especially to the line fringes which are easily abraided
in fluttering.

The acti(m of chlorofVn-m l)eing very rapid. T have used
a bottle, fastened to the cork of which (inside) was a small
bit of sponge, which I kept moistened with this anaesthetic.
Into this bottle I introduced the insects fr(»m the net,
transferring them in a few moments to the cyanide bottle.
They hardly fluttered and the fringes were preserved. Some
collectors use a needle fastened in a little Avooden handle
as an implement for impaling ]\Iuths resting on fences,
trunks of trees, in the daytime. The pinned ^Moth is then
quickly introduced into a small close box in which a chloro-
formed sp(mge is fastened. The ])in must be carefully used
so as to transfix the moth through the center of the thorax
and avoid destroying the thoracic tufts. If this method is
objected to, the resting Moth may be covered by the chloroform
or cyanide bottle. As cyanide is a deadly poison, too much
care cannot be taken with it. A solution of arsenious acid
and nicotine (extract of tobacco) may be used to kill larger
moths; the pin used for the specimen being first dipped in
this solution. It has been also reconnnended to use a
hypodermic syringe to introduce poisons. I myself have
only used the two sorts of bottles, chloroform and cyanide
and which have answered the i)urpose sufficiently well.
Individual experience must determine the best methods.

The operation of setting Moths for the Cabinet is one
requiring great nicety and care. The specimens must not
be allowed to get too dry, as then the wings cannot be

8

''

broiiglit into tlie required position witliout forcing them too
roughly. The h)ng German pins, made especially for the
purpose should be used, and setting boards of soft pine
wood of dittV'i'ent sizes must be kept in readiness. Black
or silvered i)ins are the best to use. In Germany the
Naturalist shops sell setting boards of which the two sides
are fastened by moveable screws, so that they can be
shifted to suit the size of the insects. They are about
a foot long, a convenient length, with cork beneath for the pin
to enter. A well set Moth should have the hind edge of
the forewings on a line with the thorax behind, and the
liindwings brought up so as to leave the abdomen free. The
wings may be fastened by strips of glazed paper fastened
by pins, and the wings should be carefully brought into
position by a stout bristle fixed in a handle and applied
against the veins of the costae, so as to avoid making holes
in the wing itself during the operation. In this, as in all
pertaining to the practical side of the study, experience will
suggest many things to the collector, Avho will naturally
take pride and intei'est in having his specimens look Avell.

The best months for hunting the larvae of the Hawk
Moths are July and August; and one of the most prolific
spots, a vineyard.

Caterpillars may be prepared for the Collection in their
various stages to illustrate the growth of the species. For
this purpose they must be first killed by being placed in
a chloroform bottle. The dead caterpillar should then be
placed between tAvo pieces of blotting paper and, by a
gradually encreasing pressure of the fingers, the contents of
the body expressed out of the anus, so that at length
nothing is left but the empty skin like the finger of a glove.
Care, by avoiding sudden and unequal pressure, must be taken
not to break the coloring cells of the skin ; with the best
of care, however, green caterpillars lose their color under
the operation. The empty skin is then to be fastened, by
the introduction of a small tube in the vent, to an india
rubber inhalator (such as can be had at any drug store)
and forcing the empty skin gently full of air, keeping it

avail himself of such a plan. As it was. 1 noticed that
many (d' the frailer types of Ztdler had become broken; the
points of the pins blunting or breaking oil and the specimens
sutfering under tliis treatment. In (rermany turf and other
cheaper materials are used as a substitute for cork. All
this may be left to the choice of the collector. The plan
upon which I proceeded, was to make boxes, of a book
shape, being a little longer than wide, having a pane of glass
for the top and one for the bottom. The glass was fitted
in a morticed frame and fastened in position by three-cor-
nered bits of tin such as glaziers use. Tlie boxes were
abotit 12 X 1-^ inches, but their size is a matter of taste.
The frame must be fully 2\/l' inches deep clear of the glass,
to prevent the heads of the pins touching the same. After
fastening in the bottom glass. I arranged small line cut
corks at regular intervals in the box, guiding myself by a
sheet of ruled paper beneath, and fixing the corks by means
of a cemenr, made of goldsize and red lead. Mr. W. T, Davis

Il

10

informed me that Stratena, a common cement, answers the
purpose ver}' well. The intervals between the corks are
regulated by the size of the specimens to be placed in the
box. TVhen the box is filled, each specimen carefully pinned
in the center of its cork, the top glass may be fitted and
fastened in the frame and the edges pasted over with strips
of paper to exclude dust and mites. The advantages of this
method of preserving the collection are, that both surfaces
of the specimens can be viewed without opening the box ;
that dust and insect enemies, such as mites and Anf/ircni,
are guarded against without the use of poison. These boxes
are also very (dieap and can be simply arranged on shelves
like books. When filled and the specimens are to take their
definitive place in the collection, the glass can be pei-manently
closed and a list of the contents with the Family name at
the head })asted at the back of the box. The objection that
the specimens cannot be readily gotten at is outweighed by
the consideration that they are adequately preserved. Spe-
cimens Avhich are the subjects of study can be kept ad ii/frriiii
in store boxes. So long as I kept my specimens in such
glass boxes, I never lost a single one from museum pests.
If an infected example was by any accident introduced, the
damage Avas always confined to the infected specimen. The
Anthrniit!< larva would fall and, owing to its inability to
crawl on glass, would perish before reaching a second spe-
cimen. The French Entomologist, the late M- Guenee, used
to keep his types in smaller glass boxes of a similar con-
struction for their better preservation, and I had the oppor-
tunity of seeing them at his house in Chateaudun, Each
specimen should have a locality label attached to the pin
and the bottom specimen cf a series should bear the correct
Latin name and the Authority ; written labels are, as a
rule, better, being more evidently authentic, than printed
ones. The collector can pass many happy hours v/ith his
specimens, microscoi)e and notes, and happy hours are always
welcome in this life.

mysterious silences and shadowy vistas in the woods. Even
when the niotlis will n(j longer come to bait, one lins^ers,
waiting for some revelation. The moon has transformed the
prospect and in its weird light an uneasy spirit seizes one
to adventure farther yet. Beyond that tree, half in gloom
and half clothed in gauzy light, some forbidden i)rocession
moves and we have forgotten our entomological (luest in
remembering nursery tales and catch ourselves hoping to meet
the Old World Fairies, as if they, too. had emigrated, under
the pressure of these bad times of incredulity perhaps. But
oftenest I turn the shadows into Indians, and when the
Whip-i)oor-will is suddenly silent. I believe they are coming
at length, with King Phillip leading the last hope of these
ghosts who rebel at fate in their red graves and at the order
of things, the white man with his physical ritle and intellec-
tual cannon of Evolution among othei-. And then my favorite
Indian of them all, Wannalancet, warns me again in time
and I rout all these spectres, res(dving them back into their
true shape with the heartless magic of reason. But I have
often been out all night in the woods, and slept, too, in my
blanket by a little tire, as good an Indian as any of them.
As such time I was not (X)n(;erned chietly about moths. I
was curious to find out v.hat happened and how the world
got along in the dark. It seemed on the whole very
Avell and without any necessity for a doctor. In the dead
of the dark, the pale C^ueen of the Night ^lr//V^s• Lmm) swept
by me, with the green moon-light reflected from her wings.
A strange life these insects lead and one feels like
asking the winged butterfly if it has any recollection of the
time when it crawled about as a worm, or clung tenaciiuisly
to a leaf or branch, the very opposite of this final fantastic
life in the ether. And, again, if it remembers the days
whicli it passed cramped together in its chrysalis :

awaiting, nuimmy-like, Avith iiatience, its day of deliverance.

first resting i)laces after the fatigues of the night. On Staten
Ishnid in.v early lising was rewarded by many cai)tures at
the hour when the Cat J3ird sings and betrays, to none but
chosen ears, lier relationship to the many-tuned ]\Iocking
Bird of the South. Later in the day she utters but the
peevish cry which lias suggested the conunon name. On one
such occasion I discov(n-ed. resting on a wild vine, which
grew on the South Beach near the sand and tlie waters of
the Bay, a pair of of the (xreat (jreen vine Hawk, P/iilaui-
j)chis pdHt/ofHs. One, I took, but the other escaped me,
fiying directly over the Bay and out to sea. So far as X
could watch its arrowy Might, over the smooth expanse of
ocean, it kept its course towards the Atlantic, cleaving the
saffron colored air, now turning golden under the rays of the
rising sun. These are tinier f/xihtssiplii/df than the Sea
Swallows. But the sea gathers in all such wanderers, with
othei-, larger prey. They go gaily for a time but the wave
beneath is endless and receives them at last. However, chan-
nels, rivers and bays are safely crossed by our Butterflies
and Moths. Farther u]) towards the hills, on the rocky
bed of a brooklet, I found si)ecimens of that moth-like butter-
fly F(')iis('r(( Tdnpi'miiis, abroad early but yet sleepy, still
carrying into the New World the memory of the rapacious
Roman of the Old, no doul»t with miniature sins of its own
to answer for. My specimens from the j\Iiddle States led
me afterwards to unite J'orscin/a of S('U(hler as not different
and a certain odd impression, that we had to do with a
mas(iuerading moth, to study its structure and make the
new genus for it and take it out of the (;omi)any among
which Btjisduval had scientifically classed it. Thus certain
hours and places, lanes, along which the green tiger-beetle
flew up ever and anon before my boy's feet, marshalling the
way that I should go, come back to me again out of
the years of my early studies, intoxicating my memory.
Poe says that j(ty is not gathered twice in a life, as
the roses of Paestum twice in a year. But I gathered
tlien so much that it lasts until now, when world-griefs
hold me fast.

In tlie Hawk Moths the species are all usually readily se-
parable. I have shown in the Lepidoptera the existence of
Frofioirra, that is of o-eneric groni)S of forms which are
nearer related to each other than is usually the case ; which
are. perhaps, in some stages of growth undistinguishable.
Such genera are HotuJciica, Datdua, Niulata, etc. We may
conclude that these species are of recent separation. In the
Hawk Moths such instances may be offered perhajts by the
typical group of H('iii<(ris aud again b.y fj/i/o. The necess-
ary studies on this i)oint are, however, wanting. We may
regard theoretically all species as only i-elatively stable;
practically we have to iind out the cycle of reproduction
and be guided by these results in our nomenclature.

Butterflies and Moths can be collected every where in
the habitable globe. Even the Arctic regions are not with-
out their species, while it seems likely that certain Moths
still show themselves in the farthest North when the Butter-
flies have ceased to fly. With a change of Continent we
have also a change in the kinds of insects. As we approach
the Tropics, Butterflies und Moths become more plentiful in
kinds. But, even in the same degree of latitude, there is
a difference in the numbers of the individual species to be
observed in different <iuarters of the globe. Thus it has
always seemed to me that Butterflies und Moths were more
plentiful in America than in Europe. And, as a whole, I
think the American Lepidoptera are gayer, nu)re beautiful
and certainly more numerous in species. In this connection
I remember what Lin!.aeus wrote about American plants:
Nescio quae fato facies laeta glabra plantis Americanis !

AMiile I am writing this in my European exile, I hear
a fluttering at my window and I see that a specimen of the
"Kleine Fuchs", as the (lermans call Voncssa rrficnc, has
strayed into my room and is beating against the window
pane. The sight of this species recalls to me the fact that
I am far from home. I have just interrupted my writing
to open the window and let it out and I noticed, as
I did so, that my neighbor, the Poet, was in the garden

14

gathering inspiration from the Koses. He repeated to me
his verses :

Die Rosen gelieii auf

l)or here, the Musician, and we live (piite happily, respecting
each other's foibles and having a large bond of sympathy
in common, as might be expected from a Poet, a Musician
and a Naturalist. I shall read this chapter to them, if no
more than from a system of revenge for having myself been
obliged to listen to a poem and a song which they have
recently produced.

The Species of North American Hawk Moths.

1 he Authors who liave written extendedly upon the
Nortli American Hawk Moths, or Spliiufiidtic, are Harris
(1839), Walker flSSG), Clemens (1859), (4rote und Robinson
(1865), Boisduval (1874), Butler (1876). (^rote il877j and
Fernald (1886). Of these Walker, Boisduval and Butler
have described our species in connection with those from
other parts of the world. Since 1865 groups (sub-families
or tribes) have been recognised, although these were more
or less distinctly indicated and in i)art named by oldei-
Authors, in particular by Hiibner. Unidentified descriptions
are discussed by me in Papilio, 2, 170.

In the present Avork*) I have gone over my notes and
earlier papers on the family, maintaining my 'se(|uence of
the genera, which had been in the main i-ecognised by
Butler. My manuscript was intended as a chapter of an
extended work on North American Moths, which awaited a
publisher, when the appearance of Professor Fernald's pam-
phlet upon the "Sphingidae of New England", induced me
first to send my list of the species to the "Canadian Ento-

part of my work by the light of Professor Fernahl's researches,
which were so extremely valuable from the new charac^ters
used and which often vindicated my pi'evious generic sepa-
rations. So completed, the work is here ottered to the student.
Tt eml)ra(^es a few forms not occurring in New England and,
although not so full in its account of the species and groups,
may not be without sufficient interest as to warrant its
issue as a work of reference.

The Splii)>(/i(hir are a highly organized and specialized
assend)lage of Moths or Night Butterflies, having smooth,
hairless larvae and seem to me an outgrowth of a spinose
or bristly haired larval grouii, the posterier spine or caudal
horn being developped ])r(d)ably from one or more spines or
bristles, the base of which has been prolonged and stitfened
by deposits of chitiue. in form and structuie 1 believe they
are neai'est related to the ('rrafocaiiijiindr a subfamily of
BomhjicKhic, and separated from allied Haturnian genera
(such as Hrnnlt'ttr(i) by myself and Mr. Kobinson in 18()().
The SnicrinfliiiKic are probably descendants of thecddest forms
of the Sj)JiiiHii(l((t'. On one side they may have given off
the higher series, (^liocnK'tinipiiHic, Mdfroi/IossiiHic, on the
other to the lower, SjiliitniiiKtc, Arlicnntfiiiar. The anal liorn
is a simi)le thin black spinule in Dnjontnipa riihicHudu, the
lowest foi'iu of ('ff(ih)C(n>ij)iii(i(\ stouter and more developped
in th'^ higher Anisofa s/ifpiui, and becoming, with the entire
armature, complex and well developped in the higher genera
of the subfamily such as Cithcfonia, Sphiiuiianiijxt, Kavlcs.
The bristles are gradually lost as the caudal horn became
variedly formed. The pupation is similar, beneath the sur-
face, without cocoon, an unusual one in the Ihni/lii/rcs or
Spinners. Very interesting is the discarding of the larval
horn in the later stages in certain genera of Hawk Moths
and the substitution therefore of a raised ocelloid spot. That
it should occui; in two grape-feeding genera Thi/rc/is and
J*liiIfi,ii))('J/(s, warrants me in associating the two gi'oups in
which it happens. The i)oint of my arrangement in fact
lies in considering the (liocronniijiii/ar as next to the Ma-
cnuilossitxtc and following them by the Siitfrin/hinac, to which

17

I give a central position. I find among tlie North American
genera evidence from which I follow this latter group with
the SphimjhKU-, terminating the family with the Avhcrontinne,
a tribe not found in the New World. It will be seen that
I do not agree with my friend Butler that the Cnsi<inae are
at all nearly related to the present group. With the Hepi-
aJiiKw (from which I sei)arate them Avhile Packaid keeps
the two together) I believe the Goat Moths to be very low
liomhi/crs and Butler himself points out antennal features
which warrant this view of their structure. I should not
consider the resemblance between my genera Frirmoxi/sfKs
and Jj'pisps'ia as being more than casual.

When coal was being formed, there were probably already
differentiated the progenitors of modern Butterflies und Moths,
nocturnal creatures, obscurely colored and banded, perhaps
with ariuatic larvae and active pupal state, living in those
literally darker days of the world's past. The gayer tints
came in their endless diversity with the daylight and the
flowers, probably differentiating comparatively rapidly. From
the Moths, the Day Butterflies proceeded, under certain con-
ditions and in certain localities. So far we may be safe
with our imaginative science; but, when we come into the
region of exact details, we are at fault, the story of all this
development can only be guessed at, traced by the steps
which have been impressed on the structure and ornamen-
tation of the larvae and perfect insects. Probably whole
families have become extinct; in the North American FnJpo-
Jiesperidne are the few survivors of such an extinct assem-
blage, lying between Castnia and the lowest Butterflies. With
the Lepidopfcra, as with all life, there has been the same
remoulding force at work, but these frail creatures seem
to have escaped, by their very lightness, some of the grinding
processes of time and circumstance. According to Scudder,
a specimen belonging to the Sphiiiuidac has been found in
amber : I have seen no mention of other fossil remains of
this group. This group of Moths must have been influenced
by flowers in their developuient to a large extent. Tiie dis-
tribution of Butterflies nnd Moths is assisted by wind currents

3

18

and rivers, by valleys and by plains sheltered by trees. It
is impeded by mountains, deserts and the ocean. We have,
in North America, essentially one and the same general
Fauna, until we reach the Tropical Insular Fauna already
colonized in South Florida, and, in the west, the Tropical
Continental Fauna which stretches upward from Mexico into
Texas and the South West Territories, while, on the high
lands of Mexico, it is probable that members of our Tempe-
erate Fauna drift down. Yet the Rocky Mountains, the
back-bone of our continent, has influenced a West Coast
fauna which, in several cases, has preserved more features
of the former Arctic fauna from which the European is also
descended. There is a constant iiux of species from South
to North during the Summer of the year and in this way
we have received many tropical visitors whose foothold in
our colder climate is more or less precarious and uncertain.
The question of wintering comes up, which these summer
insects are not accustomed to discuss and cannot practically
solve. Hence the Cotton Moth (Alofia argilJncen), notwith-
standing all its ravages, does not hibernate successfully over
most of its territory : the line of its successful hibernation
not having been ascertained as yet and this point in its
Natural History, so necessary for the Practical Entomologists
to knew, is neglected in the Eeports I have yet seen. The
larvae of the Sphinriidac have not yet received a comparative
study, although most of them are known; the descriptions
should be drawn up commencing with the thoracic segments
1—3; then abdominal 4 — 12; the head should be described
by itself; mere descriptions, however full, without comparisons
are tiresome and hard to undeistand.

At mid-day the Bee Hawks, HenKiris, may be taken on
flowers as well as probably all the Macroglossians with entire
wings such as Lcpiscsia. Those with angulated wings,
Amphion and Tlnjreus, also in the dusk of evening. I have
taken also the higher genera of the following tribe, Deilcjthiln,
FhilamjH'his in the day, but the Snu'rinfhini and Sji/ii)i(/i)ii
are crepuscular and nocturnal in their habit, so far as I
know without exception. There is then a correlation between

19

habit and structure and tlie liij^lier, cocoon-making forms, have
a tendency to overstep the usual behavior ot tlie Hctrrocera
and become day-tliers. Few occupations are so attractive
to the collector of Lepidoptera as the study of Hawk Moths,
from the size and beauty of the specimens. Comi)arative
studies are now needed; lenothy and detailed descriptions
of the different stages are scattered by various hands in our
literature, but they are undigested and to a certain extent
unused, if not in themselves useless.

As compared with the Hawk Moths of other Continents,
the North American species suggest several points of interest.
And first, the ancestry and origin of the group may not un-
likely be determined in our fauna, as I have pointed put,
by the study of such oldfashioned Moths as are our Dryocani-
pians. The somewhat i-emarkable larva of AtrcHs plc})<'iHs,
found by me on Staten Island on the common Lilac, a
cultivated shrub, first led me to a suggestion of this origin
taken in connection with the larvae of Dri/ocawpa, Anisota,
of which T found thi-ee species on oak, and of Fades, which
I found on horse-chestnut. Already in 1865, I venture
(Sphingidae of Cuba, p. o) to make some generalizations on
this head and subsequent studies have only confirmed my
belief that in North America are survivals of older groups
of Lepidoptera to be found, which will throw light upon the
genealogy of the present families. I draw attention on that
occasion to the larva of Cerahmia, and the late Benj. D.
Walsh, who wrote me some interesting letters at a later date,
has made some valuable remarks on the structure of the
larva of Sp]iin(jicampa. although his breeding experiments on
this species, hicolor, were defectively conducted as, years
ago, I fully explained. Later writers often overlook papers
issued some years back, a piece of inexcusable inattention.

When we study the general distribution, it is seen that
the higher groups are rather fuller and better represented
in the Old World; while the gray, moth-like Sphiuijinae
maintain in the Ncav World a larger number of forms.- As
compared with the Asiatic, our representation of the family
is more sombre-hued. owing to tlie absence of a number of

^

20

brilliantly colored Cliorrorainjiiiiac inhabiting tli63 Himalayan
region. The Cliorrommpindc are, also, the swiftest tliers and
widest wanderers, with their [jointed bodies and beautifully
curved, sharply outlined wings. As Europe is visited by the
celebrated Oleander Hawk and Dri/rpliihi crlvrio, which come
from Africa, so we receive from the West Indies the visits
of the Blue and Green Hawk, Anjeux, and the Wandering
Bee Hawks, AcJhpos, those '-JMother Cary's Chickens" among
the i\Ioths. In North America the Smvrinthhae are repre-
sented by several beautiful species belonging to the more
typical, ocellated group; both CaJasifniho/Hs and I'aotiim are
exceedingly richly colored and here the advantage is with
the American, when conipar(;d witli the foreign species be-
longing to this northern group. As a survivor of a former
Arctic fauna, we have, in California, a Smcrinthnu related
to the European (nrlJafiis. But the less typical genera ot
the group, with unocellated secondaries, are feebly represented
with us; of our two genera and species Cn's.soi/id Jui/Jdndis
is the only peculiar American form. In the Sphiitfiii/dc the
series of genera are more peculiarly American; tlie number
of gray and blackish speci^is recalling the Noctnidae in ap-
pearance is noticeable. In Europe, the numerous species
of Bcilcphila are the remarkable features of the fauna; we
have only two, both borrowed from thence, survivors of an
extinct boreal representation of the family.

In the present work I mention the species inhabiting
the Middle States, having in particular the State of New
York under consideration, wdiere most of my studies (either
at Buffalo or the country about the CUty of New York) were
conducted. As to the Florida Colony of tropical species,
or the West Coast fauna of which I know but little, an
account is given in other papers, the species being enume-
rated in my list above alluded to. My only synonym in
tliis Family (and it might be well if my critics could show
so clean a record) is Lepisesia vicforine from California, which
is said to be Boisduval's Pferogon Clarhiae, a species I do
not know. But my description was excusable since I was
led to expect a species with angulated wings and resembling

21

Abbot's figure of P. (iaurac in Boisdiivars insect, certainly
not a Lcpiscsia, an insect reseniblint? our Eastern L. flnro-
f((Kri(ifii. y\y type in Cambridge Museum must be examined
and compared at the first opportunity. In the meantime
I have here brought my work on this family to a final
conclusion, having gone again over the literature and ex-
pressed my definite opinion as to the structure, generic cate-
gories, synonymy and nomenclature of the species discussed.

This diurnal series need not detain us here and I would
merely refer to my "Classification", in which I show the

type, synthetic as embracing characters of both series, is
the Taleohi'spcridac m., a Family regarded by me as of
equal value to the Hcspcridac or FapUionidnc. Under the
name Castnioidcs, the type is shown by Prof. Riley to be
a Butterfly; when I first examined it, the spinose legs led
me to regard it as a Castniid after Walker. I believe to

when the male ;in<l larva are known, my classiHration of
the moth amoiij; my ('rrafocKnipiinir, will he tested. But
the moth has pectinate antennae which serm to ditl'er fi-om
this gronp. Kor this and other reasons, I hidieve we have
to do with an external feeder, representinj? an ancient complex,
havinj.? the (diaracters of ditferent f,n'i»iips (d' the lower liom-
byces iind. as I say, "structurally remote frum any described
United States genus/- From such slender material 1 may
be wrong to di'aw a decided comdusion. but 1 have long been
of th(! opinion that wi; should find older existing types in
North America than elsewhere and 1 mentioned this to my
kind friend and ex(dlent lepidopterist Mr. Arthur <l. Hiitlei-.
when 1 last had the pleasure of seeing him and studying
the unrivalled collection of fhiwhifcidar in the Hiitish xMuseum.
For it is in the HdhiIijii itluc that we must expect Just such
discoveries in the Moths. We have certainly the oldest
type of Butt(!i-Hy now surviving in our J'd/i'olif's/icrn/ar. And
this type tends to biidge the gap between the two series,
so that Ave can feel more certain that the primitive type of
the Order Avas a Moth, and that the ButterHies are a later
development keeping pace with the flowers and the sunlight.

Series II. Heterueera. Night Butterflies, Moths.

I refer to my original paper (187;{) on the differences
between the Butterflies and Moths. This does not lie so
much in the structure of the antennae as in their position.
In the Butterflies they are more uniform in length and type,
more rigid, directed upward: in the moths more varied, flex-
able, directed backward along the plane of the body, more
susceptible to impressions. The eyes, although functionally
incomplete and many-facetted, are probably of greater use
to the Butterflies than to the Cloths ; in the daytime, no
less than at night, the Moths depend more on the antennae,
as may be seen by the quivering motion of these organs

:!|

24

before taking fliglit. I liave seen these fundamental distinc-
tions stated by no otlier author. The rigidity and uniformity
of the antennae in the Butterflies point to a decrease of
functional use.

Joined to such diverse antennae, the extremes of which
I liave given as represented by HcpiaJus and AdeJa, we
have a great diversity in size and shape among the Moths
as compared with the Butterflies. Tiie tiniest Tineid is no
larger than the diameter of the eye of the Great Gray
Banded Owlet, Tlnj^ania, from the Brazils. The wings are
various in color but especially in outline; they have clear
spots, looking like holes, Attacns, Apntelodes, Selenia, or
nearly scaleless, Sesia, Houaris. In this latter the scales
are present on leaving the pupa, and hence this may be a
more recent form. The wings are entire but again are
ragged and broken in api)earance ; in one group they are
rayed. As the Fi/ralidnc and lower families have more than
two dorsal or internal veins on secondaries, a section has
been separated under the name of Microlepidoptom, as con-
trasting with all the rest, known as Macrohpidoptrra. But
the present classification into two Series by Boisduval and
Dumeril, seems to be both sufficient and natural. I have
found some American Pi/ralidac with only two internal veins,
so far as I could see. The Moths farther contrast by their
more woolly, tufted or hairy bodies, their nocturnal habit
and a number of details adaptive to their mode of life.
Most interesting are the American genera Sphida and Ar;;ama
among the Owlet Moths, the larvae of which, as discovered by
my friend Prof. Comstock, are aquatic in their habit, re-
calling the previously known Pyralid genus Catachjsta in this
respect. The presence of a frenulum and hook on the wings
further cliaracterizes most moths. In the males the frenulum,
arising from the costae of hind wings at base, is simple.
In the following Family of Moths, the large size, and rapid
flight has given them a position in the front rank. The
first division into groups, as now adopted, will be found in
my Sphingidae of Cuba, pp. 17 — 18 (1805).

of fine lines extending from apices to inner niaigin, divei'ging
inferiorly ; liindvvings black with a snl)tei'niinal row of wedge-
sliai)ed yellowish spots. Larva on Button weed (Spermacocc
(/Jahra). Rare in Canada and P^astern States, more conniion
in the South ; it has at least two congeners : I>. KohiiiNoiiii,
Grote, in Cuba and I>. Fal<*o, Walk., in Mexico: com-
parative studies must be made with other forms referred by
Butler to Clioerocawpa, a genus with European types.

]>oili>|»liila. Ochs.

Head moderate, untufted; tongue about as long as the
body; antennae enlarging to tips which are "provided with
a slender bristly hook: abdomen smooth, cylindrical, stout:
tibiae unarmed: fore tarsi with a row of curved spines ahmg
the outside : wings entiie, evenly margined.

C'liaiiiiK'iierii. Hanis. Ke))resents the European
(Uili), of which it seems a variety. The American specimens
differ by a warmer tint on central fascia of forewings, which
fascia is not excavated inwardly at base and not so continued
superiorly, while our s])ecies has a distinct apical black
streak: the hind wings more i)urely roseate. Not uncommon.
Canada to Middle States. In Cuba I>. <'«lverlc\vi takes
its place. Larva on grape and Evening Primrose as well
as Epilohium.

liiiieata. Fabr. Differs from the European Lironiira
by a third, central white stripe on the tegulae and by the
abdominal markings. Olive brown with a buff stripe on tore-
wings from apex to base and the veins marked with white :
hindwings black with a central reddish band enclosing a
white spot near the margin. Very common, flying also in
the middle of the day on flowers. Canada to West Indies
and California. Ltirra on PortHlacra and a large number of
plants, very variable in color, caudal horn yellowish and
rough. May to September; double brooded.

Philaiiipeliis. Harris.
Allied rather to Dcilcphila. though differently colored,
the head being also more i)rominent, the tongue longer: the

in Ih'iloiirJic. than which this is wider winged, heavier, dithe-
ring by the cylindrical abdomen being armed on the hinder
edge of the segments. In some respects the typical genus
of the group; larvae on grape and Amprlopsis.

Tit In. Drury. {Jussicmic Hiibn., fasr in/us Sulz). A
handsome species with bright olive green i)rimaries, displaying
a pale flesh colored stripe from apex to middle of the base
and crossed by a similar one from middle of hinder margin
to (»uter fourth of costa ; hindwings rose red within, inter-
rupted by whitish green hairs separating the rose red outer
band, which is margined within by a black band; the rose
colored terminal band is ended by a (piadrate brown spot
and distinguishes the i)resent sj)ecies. L(irr(( on the grape.

Uiiiiei. 0. a. li. This si)ecies, found only in the
South, has been confounded with the foregoing by a number
of writers and the synonymy became embroiled in conse([uence,
until we tigured and described it. Daik olive green, more
robust than Vifis; the bands on anterior wings are mixed
with white : the V-shai)ed space on internal margin large
and not enclosed on margin. Hindwings green ; a large
rose-colored space on anal angle and along internal nuirgin ;
a large black si)()t within : two narrow nu^dian lines : a broad
subterminal black band : terminal space narrow, dull ochrey,
nowhere pink and thus unlike Vifis. Both these forms are
connuun in West Indies and South America where they feed
on grape: the present is tigured by Cranu^r under the name
I7//V.- but Drury, the A\'iener Verzeichniss, Abbot I'^c Smith

Panilorus. Htibn. {Satellifia Harris.) This species
inhabits Canada and the Northern parts of the United States
and differs speciiically from the South American P. sateUitia
of Linnaeus. Pale greenish, marked with spots of rich olive
green. The forewings have a large olive green spot on the
middle of hind margin and a triangular spot of green rests
on the hinder margin just within anal angle, while another,
more ' diffuse, rests on costa a little within the apex ; the
wing is crossed by various shade lines and the veins are
partly marked with ochrey, a character often escaping notice.

*) During the life-time of this distinguished Naturalist and most success-
ful lecturer and teacher, I was invited to study the Sphingidae in the
Museum, but was unable to visit Cambridge at the time. The collection
there contains but two or three of my types, sent me long afterwards
for study to Buffalo. My letter from Prof. Louis Agassiz was as follows :

Dear Sir!

Cambridge, Dec. 11th- 1866.

In absence of Mr. Uhler, who may however return in a few days,
I cannot say whether the collection of Sphingidae and moths are likely
to be sufficiently extensive in your estimation to justify you in coming
to Cambridge to work them up. Meanwhile I would say that if you
decide to come I shall give you every facility I can for your work. I
would be glad to see that part of our collections worked up. My son
has already written to you what the rules of our Museum are; so I need
add nothing upon this point. Mr. Uhler could give you more accurate
information than I can concerning your arrangements here.

Very respectfully yours

a band of same color witliin outer margin whicli changes
into lines and black spots towards the anal angle, there
being no roseate patches or bands as in other species and
as we see in the species of IkUcphila. Common. May to
August. Larva on grape, becoming brown at maturity,
when the caudal horn of its first stages is discarded. Mr.
Bunker of Rochester, N. Y., describes the larva and speaks
of the number of broods.

Achenioii. Drury. This species is pinkish gray with
lovely rich brown patches, much as the deep green ones in
Pamhrus. Hind wings pinkish with a spotted, pinkish gray
border. Larva on AmpdopKis and grape. Common and
widely distributed. It is a curious fact that we have these
two colors brown and green represented in the larvae and
moths of so many species of Hawk Moths. This brown
FhiJampdm has an ally in M'^.xico, and contrasts strongly
with the numerous green species of the genus in color.

Subfamily Smerinthinae.

Anglice: Eyed Hawk Moths.

In this tribe the larvae have a cordate head and granu-
lated appearance; the moths have the head usually impromi-
nent; tongue short and membranous; the body clumsy and
the flight heavy and nocturnal; the typical genera have
ocellated hindwings. The typical genus Smerinthus is con-
fined to the West coast. Food plants, in preference, Bosaceae.

Calasyiubolus. Grote.

Head small and sunken, more or less tufted between the
antennae, in some species marked like a ridge; labial palpi
short; segments of abdomen and tibiae unarmed. Forewings
with the external margin even and more or less angulated
not dentated.

35

a. Antennae of the male biciliated ; tibiae unarmed.
Subgenus ('(iJ(is!fnihoIi(,s. Gr.

ANtyliiN. Drury. Our liandsomest species, of a lovely
rosy brown or cinnamon color, sutfused with lilac: the tints
recalling those prevalent in certain Saturnians or Juniohiidar.
Forewings but slightly angulated, with a purplish shade on
internal margin and crossed by faint darker lines; a yellow
spot at anal angle; hindwings ochre yellow, shading into
rosy brown outwardly and a round black ocellus with a blue
pupil rests on the wing near anal angle. Rare. June, July.
Larra on Swamp Blueberry (Vacvinium). Canada to Middle
States.

9l.yoi»N. Abbot a. Sm. This species lias the forewings
more angulated and is a little slighter while of the same
expanse. The wings are choccolate brown, darker and con-
fusedly marked by lines and shades; hindwings yellow
margined with brown and with a black, blue ].n]tilled ocellus
near anal angle. Larni on Uosacca, (Apple, Plum andCherry).
More frecpient than Asfi/his. Canada to Southern States.
Single brooded. June, July.

b. Fore tibiae with a terminal spine.
Subgenus CajrismfrinthHS. Or.

CeriNii. Kirby. This is a larger species than (ichii-
vatiis; very rare and inhabiting Canada and the Northern
States. The foreAvings are grey with wavy brown lines;
hindwings dull rosy red in the middle and bordered all round
with dull clay yellow and there is a black spot connected
with the anal angle, on the hinder part of the red, con-
taining a horse-shoe shaped spot of blue, the open part to-
wards anal angle. In the next species this spot is chuhle.
May, June. Larva unknown.

c. Male antennae bipectinate; tibiae unarmed.
Subgenus Eusmerintkus. Gr.

Oeminatus. Say. Gray, with a faint rosy tint, the
forewings crossed by an angulated brown line followed by

a brown shade and this by several indistinct wavy lines;
a lunule of brown edged with white at anal angle ; hind-
wings rosy with gray borders and having a large black spot
with two blue spots on it near anal angle. Occasionally
a third hhie spot appears on the black (var. trlpartltusi, Gr.)
and sometimes but a single spot is found {rar. Jaiiiaivensiis,
Drury). Lnrra on llosaceae, also on Willow. Not common.
Single brooded, the moth appearing in June, July. Can. to
Middle States. Drury's locality, if his indifferent figure re-
presents our species, is incorrect. This species with others
of this group brings forward the anterior margin of the hind
wings in a state of rest. In this position the lovely C. asfylus
looks like a crumpled leaf.

PaoniaH. Htibn.

Head small and sunken with a prominent ridged tuft
between the antennae; tongue membranous, no longer than
palpi ; antennae fusiform, biciliate in males, hooked at the
end; thorax short; abdomen long, cylindrical, tapering, seg-
ments unarmed ; tibiae unarmed ; forewings regularly scalloped
on terminal margin.

£xcaecatus. Abb. a. Sm. Rich brown and fawn
color, forewings crossed by sinuous brown lines ; hindwings
rosy red, with a black spot containing a blue center, bordered
with fawn color, with a yellowish patch before anal angle.
Common. June, July. Can. to Southern States. Lnrra on
Bosaceae, Apple, Plum, Cherry etc., also on a variety of
forest trees.

O^^ssonla. G. a. E.

Head small and isunken in thorax; f'^rm slender, that
of the males recalling the American Bombycid genus Apate-
lodes; palpi slim, divaricating at tip; abdomen slender, seg-
ments unarmed, with small anal tufts in male ; all the tibiae
armed with spinules; wings with the outer margins dentate.

Juglandis. Abb. a. Sm. Pale grayish fawn; fore-
wings crossed by brown lines, the females paler colored;
hindwings concolorous with wavy brown lines across the

37

middle; uiiocellated. Larva on Walnut and Ironwood. Not
common. June, July. Canada to Southern States. Varies
in depth of color, sometimes with a light purplish reflection;
distinguished by its slender form and bombyciform appearance;
structurally it is nearest to Paonias.

Triptogon. Bremer.

Stout and sphingifonn ; head small and sunken : fore
tibiae with a spine at extremity of the joint; tibiae else
unarmed ; surface of abdomen si>inose beneath the scales ;
antennae fusiform without terminal hook, biciliate in males,
simple in females. This genus prepares us for the following
Sphinginae.

Hodesta. Harris. This large moth is of a slaty gray
with darker olivaceous bands and shadings on primaries ;
hindwings with a dusky roseate central i)atch. Lana on
Poplar and Cotton wood. June to August. Canada to
Southern States (Cnhlei) where the larva is said to feed on
water plants. Not rare. A variety Occidentallsi occurs
in the West.

I

Subfamily Sphinginae.

.(

Anglice: Typical Hawk 3Ioths.

Large, usually gray and blackish species with well
developed tongue and entire wings with internervnlar sub-
terminal dashes on primaries. Larva pupating in the earth;
flight crepuscular or nocturnal. Food plants, in preference,
Solenaceae, Syrinya.

C^raioniia. Harris.

The horned larva, feeding on elm, allies the moth to the
preceding genus and the soft brown colors of the imago are
Smerinthoid. Also the head is small, somewhat sunken as in pre-
ceding group. Abdomen heavy, tapering, the segments armed on

hinder edge ; tibiae not spinose ; antennae fusiform and ending
in a small hook: foi-ewings nearly entire, with a slight ex-
cavation at vein 2: all the characters show approximations
to the Smcrhitliiiuw and warrant this arrangement of the
family.

Ainyntor. Hiibn. (Qimdricornis Harr.) Soft brown
and whitish gray, apin-oaching in its pale colors succeeding
genera: forewings shaded with soft brown and crossed by
gatherings of triple brown lines; hind wings clay color,
shaded with brown ; the fringes brown, cut with pale yellowish.
Lnrrn with the granulated appearance of preceding group.
Common. Canada to ]\[iddle States. May to August, perhaps
usually double brooded in southerly localities. In Buifalo,
N. Y., larvae of the second brood failed to mature before
the cold came.

l>arciuiiia. Walk.

Head small and sunken; antennae fusiform, with small
hook ; abdomen cylindrical and tapering, the segments armed
as in (Wutontia, tibiae not spinose. Larva without horns
on thoracic segments.

Undulofna. Walk. [I'cponi'nint^ Clem.). Gray, mixed
with yellowish scales ; forewings crossed by pairs of darker,
wavy or angulated lines ; hind wings darker, smoky brown,
with the fringes Avhite cut with brown. TMrra on lilac, ash
and })i-ivet. Not rare. Canada to Middle States. June
August. In the South are allied species: Hu)!;oiii« Grote,
in Texas; Catalpac, Hoisd., in Georgia and Florida. The
trop'.cai genus Sy~y(}ia, (t. a. R., is related.

I

l>i India. G. a. R.

Larger and stouter, with the tliorax more produced
anteriorly: antennae fusiform, with slight terminal booklet;
abdomen cylindrical, the segments armed; wings entire, ex-
cavate above anal angle; rough gray species with darker
secondaries. Bnmtes of Drury, recognised by me from Cuba,
belongs here.

Jasiiiincai'iiiii. Boisd. a, Lee. Size large, gray:
tlie forevvings crossed by wavy lines, and witli darker, brown
shadings, and smoky brown, shaded secondaries. Rarely
found in Middle States; Long Island (Hulst); not conunon
in the South and one of the rarer species of the family.

l>olba. Walk.

A smaller form than those with which it is here associ-
ated, yet agreeing in some respects with Baremma and
standing between it and Phh'(f('t/i,vifiii}<; the head is small,
though free, and roughly scaled ; the tongue longer than the
body. The abdomen is somewhat conical and peculiar in shape :
the segments armed with round spinules : the tibiae unarmed ;
the thorax approaches by its shape that of PhhujcthoniiHS,
and in colors the single species has a slight resemblance to
F. r'tsHca.

HjlaeiiK. Drury. (Priiii Abb. a. Sm.) Dark rusty
brown : thorax white on the sides : abdomen with a row of
lateral white spots: beneath white: forewings dark rusty
brown, with a white spot at base and one on disk, crossed
by dark brown lines and with an apical white shading:
hindwings dark smoky brown crossed bj- two dentate white
* lines : fringes checkered, white and brown. Lana on Ilr.r,
Papaw (Asi)iiiiiia friloixt), perhaps (Scudder) on Sweet Fern.
Not rare in certain localities. Canada to Gulf States, rather
more usual in the South. June, July.

Plilcji^ctlioiitiiiN. Hlibn.
Large species of an iron gray color Avith large, brightly

blance between this and the next genus to the Acherontinae,
an Old World group, and this in all stages.

Kustiea. Fabr. (Chionanfhi Abh. r. Sm.). Very large,
the primaries shaded with deep brown ; abdomen with yellow
spots ; a handsome species, found only occasionally outside
of the Southern States ; reported to me from Ohio and
Kentucky, also New Jersey.

Carolina. Linn. "Tobaco worm." Dark gray, the
wii'gs crossed by a number of wavy, indistinct lines; a
white spot at base of forewings and one edged with dark
scales on disc ; hindwings gray, with a basal smoky spot,
crossed by three darker lines and with smoky borders ; ab-
domen with five dark yellow spots, surrounded with black.
Larva on Solenaceae (Tobaco, etc.). Common ; double brooded.
West Indies, northward to Canada.

Celeu.«>i. Hiibn. {(^arolina Harr.). "Tomato \\ irm."
This is rather heavier than preceding and more common at
the North, I have not seen it from the Gulf States. It is
paler colored, more cinereous or ashen; forewings with the
lines more evident: hind Avings quite pale crossed by two
strongly dentated lines over the middle, a curved line •
within and a smoky spot at base of winp": abdomen with
five dark yellow spots as in preceding species (hence the
name '>-macidnta, under which this form was described by
English authors). Common, double brooded. Larva green
and brown in color, on Solenaceae, especially Tomatos, also
on Datura and Tobaco. Canada southward.

Ciiigulata. Fabr. Much stouter than the European
ConvaJvidi and shaded with brighter roseate. Very dark gray;
the thorax behind distinctly shaded with blue and yello^','
over the metathoracic tufts. Hind wings shaded with ros3
color and live rose colored spots, somewhat squarer than
usual, adorn the abdomen, separated by black bands. Not
so common as the preceding. West Indies, northward to
Canada. Larva on Convolvulus, Sweet Potato and al> on
Solenaceae.

Atreus. Grote.

Smaller and approaching SpJiinx in appearance ; the head
prominent; ej'es salient: antennae slender at tip where they
are bent; fore tibiae spinose as (according to Fernald) are
those of P. ceJf'Ks. The type is, I think, not congeneric
with the European Piuaftfri, nor can I find an Hubnerian
genus for its reception; I should leave it in PhlciietJionfius,
as Fernald f^ecms to suggest, but it ditfers in the 12- veined
primaries, the want of an antennal seta, in the fusion of
the tongue-case in t^-p pupa and in the general style of
markings no less than in the sti'ucture of the labial palpi.
Seqnoiap, Boisd., may belong to Hi/Jniais and be congeneric
with the European J'inasfri, which this is not.*)

PU'boiuN. Fabr. Forewings gray, witl' a white discal
spot ringed with black, heavy black dashes between the
veins and .crossed by faint, partly incomplete lines. Hind-
wings dark smoky brown, grayish towards base and on the
anal angle : fringes brown and white. Lonn som.ewhat rough
with a caudal horn curving only towards its tip, blue, with
irregular black tubercles: the caudal horn will be found to
play an important part in the classification, as it \aries so
much in length and api)earance. It rises from the top of
the hind segment and is a prolongation of the skin itself,
stifiened by chitine. It is sometimes discarded, replaced
by an eye-spot. It is very curious in this species and there
is a slight approach to Ac/irroiifia. Afrcxs pJcheixs, feeds on
Trumpet Creeper (Fernald) md Si/rinaa, where I have found
it. The moth appoaches the section of Sj)lii)/:r called by
Butler Liutmrin, but dift'ers much more strongly in structure.
We have, then, in Eastern North America no equivalent to
the European Ihiloicu,^ pinai^fri. A second species of Afreus
probably occurs in Cuba, described bv myself, but I have
now no types to compare.

EMeiiia. CUemens.

Head small and somewliat depressed, but not sunken
as in Snicriufhus, wliicli tliis genus approaches in its Bombyci-
form look : the wings liowever are entire, Sphingiform ; the
tongue is sliort and membranous, but it differs in the j'oung
stages by having no caudal hoin and the head not being heart-
shaped ; according to Fernald "tlie young larva has a round
head (of amifcranfui) but it changes at the first moult to
an angular form running up to a sharj) point at top." In
ornamentation this genus differs bj^ the immaculate abdomen,
also a Smerinthoid character, but the pattern of primaries
is like the en^ueing Sphhuiinac, having longitudinal streaks
on the interspaces. \\'e may say that the wings are those
of a , ,''■">' the body of a Smoriuthns. A letter from Dr.
Clemens. 'hI in 1865, and explaining his reasons for des-
cribing thk, genus, is before me as 1 noAV write. From the
first, I liave kept Klhiiia, as a genus, distinct. From the
habit of the larva and its feeding on Pines, it has always
been approached to Hijloiais, but the immaculate abdomen
at once excludes it, no less than the sliort maxillae. It is
now referred to the Snierintlni/af h\ Fernald, but the larva
does not seem to me to be that of a Smerinthoid form. I
regret not to have material now before me and I am writing
from old notes on the species, which I have seen, all but
honihifcoiUfs (this from a figure). It struck me that they
were very near and jjossibly only variations of a single form,
the conifry(iyn)n of Abbot a. Smith. Prof. Fernald, ai)parently
on Mr. Thaxter's authority (a most excellent one), considers
honiltjfroidfs and Harrisii as forms of one species. Prof.
Fernald further distingui-^b^s couifcrdrHni, while he does not
allude to pincHni of Lintn;^', a New York species, but, if
valid, certainly not confined to New York, which State be-
longs to southern New England so far as the Lepidopterous
fauna is concerned, its northeastern portion, in its fauna,
to Eastein Canada. This genus is evidently of wide distri-
bution and distinctively North American. For the present
I leave further discussion of the species. The genus itself
niiglit' inaugurate the jtresent group if my an-angement of

43

'.I

the family is retained, but I prefer to regard it (with Ere-
(Iriinn) as more related to Sphinx proper; in any event it
marks the approach of the two groups Spliii/fiitHK and
Smcr'nithuxit' and thus favors my idea that the latter group
has given rise to the former as well as to the ('liofrocfntipiiHh'.
Without material at hand for dissection. T am not willing,
from what I know now. to accept my fiiend's view that
Elh'UKi is a Smerinthoid genus. The central position I give
the Smer'nitliiiuic, expresses my idea that the other groups
may have arisen from its ancestors: while at present its
members are on the whole perhaps nearer the (.'hocrovampinac
than the Sphiiujinac

Sphinx. Linn.

The tyjie of this genus is originally held liy me to he
the Euro])ean >'. liffiisfri, and hence the genus is synonymous
with Lf(lii(( of Hubner. The head is prominent : tongue
about as long as the body : pali)i moderate ; general tbrm
slighter than in P/iJcf/ff/ioittiKs. Abdomen tapei'ing to a
point, banded and marked with white, less prominently nuirked
than in Fhlcf/cfhoHfiiis; Larrae smooth, with ovate head,
caudal horn usually straight and pointed: juipn in the ground,
tlight generally crepuscular. This genus contains i)erhaps
the typical species of the family, but not the highest in
structure and habit. The more compact sha[»e, diurnal tlight,
and surface pupation of M(icro<ih>ssinac and Cltof'ror(ni>))iif(i)' seem
to accord them this position. The European S. lif/n.-^lri has
a sutfused roseate tint reminding one of the rosy species of
Pli/('(/('fli<ii//iiis: none of (mr species have this, but hi.^vilinsd
in one sex at least, has a decided yellowish tinge. The
value of the genus encreases in North America, the species
being comparatively numerous and the ^^'est producing forms
of snuill size but great beauty, as the well known S. FAsa
of Strecker. 'J'he intersi)aceal black da^iiHs on primaries

of the genus.

As I have elsewhere pointed out the Macroglossians
with angulatcd wings form a subgroup, leading to the (!lioero-
cami»ians. The typical subfamily contains JLnxois, ArJhipofi,
Li'piscsia, 3I((rro(/!of<s(i and allies, with even wings. My
(dassitication is based on natural (diaracters, and no scientific
i-easons have been brought forward by any dissident. It has
been said that a certain (dass of nunds ditter mainly to
differ and. in the arrangement of such delicate animals, the
range of untrained oi)inion has been found to be wide.

(Considering, as I do, that the Sjthinf/idac may have
been evolved from the ancestors of the ('crahra^iphnic, I
regard the subterraneous pupation, without silk, as a low
or derivative character, together with the crepuscular or
nocturnal flight. On the other hand the surface pupation,
the use of silken threads, the diurnal flight, as an api)roa(di
to the Hcsiwr'nlac. The surface i)upation of tropical SpJiiiHiiiiar
nuist be studied in connection with terrestrial conditions.
There is a slight resend)lance in the larvae between the
Pai>iJi(>i/ii/nc and (liocrocanipiiKiv.

The generally smooth larvae show exceptionally thoracic
crests, as in Tripfonoii and ('crdfoniia. genera accordingly
related; and this would be a i-etained character, recalling
Juiclcs ii)ii)i>ri(ilis'. The rough, shagreened skin of the p]yed
Hawks in also prol)ably a modified survival. The proofs
that the passage to the Si>hi)i(/i<l(H' has been through what
we now regard as older forms of Bombyces, are thus many
and, if we place this family at the head of the Moths, it
is not that it has real affinities with Castnia, which lias
probably a different immediate origin.

The Spliiuriidao. have their metropolis in the tropins, not
snited in their habits to the cohl of liigli hititudes: the
Eastern portion of onr continent is snbject to the advent of
occasional visitors coming on the snmmer winds from the
West Indies and Florida. Among there occasional visitors
may be cited Adhipus tifau and Uniluhis, Arffcns lahnisrai',
I)ih>])]i<m()t(i rJlo. It is not known how for Sonth our Northern
species of Smcrinthinoo, Sphinx, etc., range, but I found none
of them in Cuban collections and it is probable that they
do not even reach the Gulf. With regard to classitication.
the present is considered now generally by Authors a distinct
family. It seems to have been regarded formerly as a sub-
family of "'Sj)liiii(/(\s''\ e(iuivalent in value to the ScsiUhn' or
"Clear wings."

Our Hawk ]\[oths are in part (1) descended from a
Tertiary Arctic fauna, in part (2) of South American origin,
while (8) several forms must be considered as stricth' North
American and as the direct survivors of the tertiary fauna of
the Continent. On these points various papers in ■■Pa])ilio",
"Silliman's Journal", etc., may be consulted. Genera belonging
to the /?V6'/ category are marked, in the following list, with (E),
to the socotid (S), to the third (N). These categories are
provisional and demand further studies in this direction, and
are here not fully cariied out, for want of data. The food
])lants of the larvae are deciduous i)lants, shrubs and trees,
except FJJctua which feeds on pines (('ouifcrdc). I have
found Sphinx /laJniiap on plants of]\Iountain IjRiu'el (K((hiiia)
not a foot in height, the larva being much exposed. The
larvae sutler greatly from the attacks of IchitcKHuiiiidac:
this alone prevents certain kinds of VliiJawpelxx and I'h/ciic-
fhonfiii.s' from becoming very injurious. In the South the
Catalpa trees are defoliated by Darrmma Oittdjiac. but,
strange to say, the pupae seldom give the moth. The pupation
of this group is more dangerous to the individual than in
the cocoon-making groups: interference with the larva seeking
pupation seems readily fatal; often the gr(mnd is not suit-
able and the roving larva falls a prey : these heavy, naked
larvae fall also victims to storms, by which they are shaken

4d

from the trees to certain deatli : tlieir tenacious grasp I liave
then noticed to be insufficient, although the strength of
their anal daspers is very great. The following list: may
be of service in arranging colhM'tions, fiom Canada as far
south as the Middle States, the species from Texas, Florida,
and the Southei'n States, as well as the Californian forms,
may readily l)e interpolated: these are all given, to the
total number of 95, in my lists and catalogues. I am dis-
posed to regard nomenclature and classification absolutely
correct, as far as my long experience and study can make
them so.

to adveitise that lie "covets" speeiueiis and even to con-
sider the loss of life on a Polar Expedition justified in the
capture of some rare species. When Mr. Strecker or Mr.
Neumoegen talk in print about „Science", one hears them
with a certain shock, feeling that this is not alwaj's the
correct term to be applied to a propensity for collecting
and naming Butterflies.

A more intimate relationship between the Sphinfjidof
and Bomhiicidae. is suggested by the American group of the
CetrifocanipiHao. Already in 1865 I call attention to this,
but I regard it then as a matter .: Analogy rather than
Affinity. If we regard the larvae of the ^'eratocampians,
which I have studied and described in pai, we see a loss
of the spines and diminution in length through the series
Citheronia, Anisota, Drffocanipa. These three genera are the
nearer related, the other series is Each's, Sphinf/icampa.
The larva of IJ. ridticKuda has lost all but the fore and
aft dorsal spines; the Sph'uxjidao have become smooth and
only have a ridge behind the head or the anal spine repre-
sented by a fleshy horn. I do not know the larva of
Qmdrina, which I placed temporarily at the head of the
Ccratocamphmc. It is perhaps the remains of another old
type of Boml)yces. In America we shall have probably to
do with remains of older types than elsewhere on the globe.
This I have already pointed out, regarding the CWafocampituw
as remains of an old type and nearer to the Hawk Moths
than any subfamily of the Spinners now existing. This sub-
family has short antennae and a long and heavy body, a
pupation like the N<)t()d<mf'niao and Spliinfi'iddc, very bright
colors (piite different from the Coi^s'nmc, but some JfcpialiHaa,
which I separate from D' Packard's Hepinii, are also very
gaily marked. These old types are very interesting and we
may briefly allude here to the Pah'oJifs/tcridoc, which seem
to stand between the Butterflies and Moths.

The genera of the Cemfocmtipiuup, leaving Quodrina for
tlie moment out of tho question, should be arranged thus :
jrst. Eaclea, Adi'hci'phaJa, Sphin<jicanipa ; 2"'"y' Citherouia,
Anisota, Dryocanipa. The male and the caterpillar of

55

Qnadriva (liazomu Grote, must botli be known before it can
be placed with certainty. According to my friend Mr. Robert
Bunker, Ciflierouia rajdJi,^ comes occasionally to bait after
the fashion of a Sphinx. The resemblance between the
American genera lutcJrs and (rrafoinia is pointed out by me
in 1865. I bring TripttKjuH and Ccrutowia together from
the thoracic 'iiorns'' of the larvae, resembling each other
and this Bombycid genus. I have thus two i)oints to excuse
my arrangement of the SnierinfJiinftr, viz: the I'esemblance
between Anihuli/x and Caln.^i/ntlxjhis at one end and Triptoiion
and Crrafoniia at the other. It is the young stages which
must atford us a guide in our deductions and. already in 1865,
I have seen the importance of evidence which leads me to
insist upon my classitication of the Sphintiidai- today and
the longer they are studied. As to the importance of studying
American forms there can be no (juestion if, as I believe,
older types exist here than elsewhere. Just as I believe
the species of Ba.^ilarcliia to be recently separated, I look
upon the Palcohesperidac as relics of a very old and else
obsolete type of the Lepidoptera. In the question of the
relationship of the Sph'niii'uhte and the Bowhifces, the "horn"
of Bouilnjx nwri must be remembered, no less than the
distention of the anterior segments of this larva which i-ecails
the Elephant Hawk Moths. While I think there can be
no doubt that the meml)ranous tongue in the Swffhithinac
is a retained character, the question is not so clear with
EUcnin, in which the character may be one of reversion.

TliH characters of the Family Vahohcspn-idac (consult
my ])aper, Can. Ent. 173, for the year 1875, where they
are first announced) are as follows; Eyes large and naked.
No ocelli ; caputal S(iuauuition mixed flattened scales and
hair. Antennae capitate, without terminal inflection. Wings
heavy, entire. Tibiae and tarsi strongly spinose; hind and
middle tibiae with terminal claws. Legs stout. The three
parts of the body unusually distinct. Form cylindrical. Head
broad in front. Onuunentation uuich like the Hvsprrii/oc,
brown an<l yellow. The characters by which this Family
is separated from the otJHU' Butterflies, are taken from the

following theses. That the lei)idopterous fauna of the sunnnit
of the White ]\rountains {(i.-j/cis\ Larid, Pacl/nohla etc.) is

of the tropical origin of the Cotton worm, was reached
by me thnaigh independent studies. The latter was in con-
tradiction to that point of view from which the Cotton worm
was treated in the '-Missouri Reports" by Prof. C. V. iviley.
A subsecpient attempt to deprive me of originality on the
discovery of the ''Boston letter'', not only fails when the
letter itself is compared Avith my observations, but is without
force as coming from Prof. Riley, who was e(iually unaware
of the existence of the letter with myself at the time of
reading my paper.

I have also shown the <'xistence of generic groups of
forms more closely related than is usually the case, such as
Butana, Xwhfa, the European P/i((/< ni and in our Buttei'flies
the genus Ikisilarcliiti. It seems to nie that the species in
these genera present a certain advanced stage of distinctiveness
when their interdependence has but recently ceased, they are
yet in i)rocess of separation, of hardening-into perfectly distinct
appearing species. T have called such generic groups, Fro-
yeneni. Sections of other genera, as considered by Authors,
show this peculiarity, as the typical section of Ht'iiiilcitca.
I refer tricolor to JlmiilrKcd. and in this view its color variation
becomes of more interest than when regarded as a distinct
generic type. From this subfamily, as established by Packard,
I have separated the J{c)nH<ii('i,.ar and Ceratoaniipinac, the

X. Edition to Clemens (1858) wliicli date I take as the com-
mencement of an era in which American Lepidopterists are
to catalogue the different Families of Lepidoptera and lay foun-
dation for present and future discoveries. Mr. W. H. P^dwards
describes and catalogues our Butterflies, as also Mr. S. H,
Scudder; D'- Clemens writes on the Sphingidac, Tortricidac
and Tint'Ulaf, D'- Packard on the Ziifiaenidao, Jionihi/cidac
and Gcometridae, I, myself, catalogue the Sphiiujidac, yort/iidac
and VyrnJidae, Mr. C. T. Robinson, besides working Avitli me,
connnences to figure the Tortricidac and Mr. V. T. Chambers
takes up the Tineidae afresh. Finally Prof. C. H. Fernald
catalogues the Toririciddc and reclassifies them, jMr. Henry
Edwards works up the Scsiidac and, with the publication of
my New Check List (1882), this Renascence period comes
to an end. These are its principal Authors and their work.
It spans the time from D'- Morris Catalogue to my New
Check List. It' has identified our more usual forms, arranged
them scientifically and in correspondence with the views of
the best European writers, besides performing a great deal of
original and enduring work of its own. From this time the des-
cription of our Butterflies and ]\[oths is undertaken with greater
security and this period is further notable from the appearance
of a journal, Papilio, entirely devoted to the Lepidoptera.
Above all, the work of determining the private collections
throughout the country has been performed and has greatly
furthered the interest in the study. The first period of
North American Lepidopterology was that of Abbot, Boisduval,
the elder Leconte, Say, Peck, Harris, Gosse, Kirtland and
their historian, our old friend 1)^'- J. G. Morris. The second
period, which I call the Renascence, alluding to the re-rising
of the study since Say's death, has certainly been a fruitful
one, during which a great deal of work was performed with
good humor and at considerable selfsacrifice. It deserves
a better fate than that any of its workers should have tli^ir
laurels assailed ,by those who to day rest in their shade.
It is not that very many others do not materially assist,
but the writers above mentioned are those who performed
the most work in the Butterflies and Moths and whose names

are mure i)articuhirly associated with tlie respective families
of the Lcp'uhptem of our Nortli American fauna.

As to English names for the Ameilcan species of Hawk
Moths, several liave been suggested which I have not referred
to here. I, myself, have used the following common names:
the Early Bee Hawk, for Lrpisfsla tlarnfosvidhi: the Blue
and Green Hawk, for Ariims lnl,n(s((ir : the Particolored Hawk,
tor Ani})i'h))ili<ui(i versicolor : the Wandering Hawk, for Dih-
phonola dh).

Any approach of the internal feeding ('oss'nidc. to the
Hawk Moths is, I think, unwarranted. In cimsidering the
Splii»(/i(hi' as a distinct Family, eijuivalent to the Hi»nl>iicidae
and Xoctx'uUie, special studies, such as I have here attempted,
must decide as to the rank of the component groups and
this on similar considerations as intiuence our separation ot
the Family itself. In this action, the definitions of the elder
Agassiz must be held steadily in view and we must not
wholly depend upon a generic class of characters, as would
seem to have been the course of that most distinguished of
Entomologists-Lederer.

On the whole the Subfamilies of Sphingidae may be
regarded as affording two series, the first embracing the
Macrof/Jossinar, C/iocrorantpinac and SnirrlufhiiKw, the second
the SpJiinpiiHie and Achcrontuuie, the members of each series
approaching each other more nearly than the opi)osed series.
Nevertheless the Eyed Hawks afford a synthetic type, the
family characters recalling the Snwriidhiiiac appearing in all
the groups. So the Bee Hawks approach through Drulaniia
and tlie genera with angulated wings, the Elephant Hawks
through AmhifJif.r. the Typical Hawks through Ellfimi. The
l)attern and colors, outline, habit and general structure, so
difficult to properly consider in a linear arrangement, are
best appreciated under the present classification. The short
antennae of the Death's Head Hawk Moths (Acliorontwae)
seem to me a low character; the pattern and colors, the
ringed abdomen, the contrast between primaries and secon-
daries ally this Old World group with the Typical Hawk

()0

Moths (Splii)/(iin<ii') : I liave iiotUM'd in botli a certain rcmi-
nescence of the Owlet Moths or Xorftiiddr (Sphin}^i(hi(! of
Cuba, [){). 1—2).

So strong are the characters of tlie Bee Jfawks
with angulated or uneven external margin to the forewings
(as seen especially in the larval stages of 7'A//r^/^^■. like
J'lti/anipchis Avliere the anal horn is discarded for an ocellus),
that I have hesitated as to their position. But their general
form and body tuftings decide ine that they are to be
regarded as aberrant Macrot/lossit/af, rather than a distinct
subfamily tyjie. They make a natural passage between the
two subfamily groups, sharing the flight and habit of the
one and ai)proaching the other in the young stage and food
plant. Ui)on this latter characteristic, as it generally is for
my ditferent subfamily groui)s of Splinxjidao, I lay great
value as indicating relationship. It unites the Sphinfi'uiao
and the AchcnnithKU' and shows that these two are the nearer
related and form a series. Everywhere that class of proofs
which require the tact and experience of a Naturalist to
bring out. witness for that general view of the classification
of the Sphinfi'idao which I may speak of as my own, so nnich
being either original with me or brought into new light
through my long study of the family.

The man of science observes the small changes which
underlie the endless succession of life. It is clear to him
how we are drifting if. with the rest of humanity, he does
not know ivlicrr. Witliin certain limits he believes that the
will of man counts for something and that, in the perpetual
struggle, that which is useful, good and beautiful shall prevail.
Even in comparatively so small a social field as Entomology
attbrds, he may oppose the purely selfish action, the insincere
statement, and try to correct the limited exi)erience which
prompts so many faults. From the contemplation of nuicli
that i;^. paltry and much that is stupid in the writings and
doings of Entomologists, he can at least always turn for
relief to Nature herself, standing high al)ove all the schools
which strive but to translate her. He may drink in all the
loveliness of the world and refresh his soul by wanderings

in field and forest, by expansive lake and windinj; stream.
The throbbing Sea, answering by its agitation to the pnlses
of tlie wind, will excite his longings and draw his sonl ont
after it. And, when the summer is past and the roses, by
thousand ways and voics, Nature will still amuse him until,
tired of his ([uest, he falls into the last slee^t in the arms
of the universal mother.

So, by the Lake at Buffalo, Time, winged with happiness
passed by and, feigning that he would be thus every-
where, lured me away. The world is full of beautiful butter-
flies but those that fly at home are the best. Even in the
technical works of our noted Entomologists, a local oloring
attests the force of this sentiment. Thus there is an in-
describable Massachusetts flavor about D""- Harris's book.
And, let him industriously gather eggs and caterpillars from
what part of the country he may, it is always as from West
Virginia that Mr. W. H. Edwards invites his readers to the
great feast of facts. In some way the scent of the Elaine
woods has got into Professor Fernald's writings: we seem
to know the famous bog in Orono, whereon Ociici.^ jntta
cumbrously flies; through openings in the woods we catch
a glimpse of warm-tinted Spring-tide azalea or shhi-bush
blooms, over Avhich the '-Early Bee Hawk'- (Lepisoia flavo-
fuschda) for an instant hovers to vanish again. And the
ridge by the Lake side where, of a June evening, I caught
the rare "Particolored Hawk" (uhnpclopliafia rer.si color) I
would also have remembered out of my own experiences,
the Canada shore in the distance and all about me the lovely
scenery of Western New York.

Although what the Poets say must always be taken in
a certain wide sense, I have be^-n struck by their particular
attention to butterflies. Poe declares that a certain curious
sentiment is derived from '-the contemplation of a moth, a
butterfly, a chrysalis." As to the latter he may have been
influenced by the mere euphony of the word itself. Only
an Entomologist, with prophetic soul dreaming on the glories
to come, can be moved by the sight of a chrysalis. But,
perhaps, I am wrong here, remembering the chrysalids of

VI

certain butterflies, tliose pendant, gold-studded earrings of
Nature, liung by her in moments of pride from trees and
pretty blooming plants. Buds to open, to expand, to take
their flight.

Somtimes, now, I dream of fields Elysian, where, on beds
of Asi)hodel, hang pendulous innnortal butterflies, beneath
an eternal sky. And, coming kindly to meet me, I see
Harris and Doubleday, Boisduval and Say; while, with his
nervous manner all gone, I find again Francis Walker, his
good work all remembered. And he forgives all I have said,
as I ask his pardon, because it really was (and I have been
there myself j very dark in the entresol of the British Museum
where he had to work. But here it is Light at last and
an everlasting Sun is shining.
