MACROLEPIDOPTERA "''^'^r>.

By Edward Meyrick, B.A., F.Z.S., F.E.S.

In this paper are included all the Lepidoptera except the Pterophoridae, Tortricina,
and Tineina, which have been entrusted to Lord Walsingham. I propose to give a
complete enumeration of all the species hitherto observed in the Hawaiian islands,
describing the very numerous new species, and also redescribing those species of which
our former imperfect knowledge has been enlarged by the acquisition of new material ;
and also to discuss some general considerations arising from the study of these forms.

I have not thought it necessary to quote the synonymy of the species, or to give
references, except in so far as these have actual relation to the Hawaiian Islands. The
accurate record of localities is in the case of this fauna so important for purposes of
comprehension, that I have thought it best to particularise the number of specimens
obtained from each locality, so as to indicate the value of the available evidence. On
the other hand, the season of capture seems to depend in most cases only on the
presence of the collector, and the impression derived from the records is that many
species are probably obtainable throughout the year.

§ 1. General considerations on the Macrolepidoptera.

In the following enumeration 292 species are recorded, of which number exactly
200 are now described for the first time ; these are assigned to 49 genera, of which
6 are new.

Relation of Genera and Species.

Of the 292 species, 31 occur also in other regions, the remaining 261 (or 89 per
cent.) are endemic. Future discoveries are more likely to increase this percentage
than to diminish it.

Of the 49 genera, only 10 (or 20 per cent.) are endemic, the other 39 occur
elsewhere. The endemicity of the species is therefore four and a half times as great
as that of the genera. It appears to me that this ratio, in the case of a highly endemic
fauna, is an index of the same significance as is the proportion of species to genera in a
highly apodemic fauna. If, as an example of the latter, we take the Lepidopterous
fauna of the British Isles, as enumerated in my Handbook of British Lepidoptera, we
find 2061 species and 458 genera, the ratio being 4^^ to i exactly. I interpret this
index as a measure of the comparative periods of time required to produce specific and
M. F. H. 17

124 FAUNA HAWAIIENSIS

generic characters, signifying with considerable precision (for I find the same result in
such other faunas as are available for calculation) that on an average it takes four and a
half times as long to produce a genus as to produce a species.

In the Hawaiian fauna, however, the proportion of species to genera is unusually-
high, being 6 to i, and it may be asked why this is so. It appears probable that,
owing to the extremely limited character of the fauna, and the relatively very small
number of genera available in the first instance as a base of development, the generic
competition has not been sufficiently severe to promote a high rate of modification :
whilst the variety of situations presented under similar but slightly different conditions
(such as those depending on altitude, rainfall, and insular separation), is highly favour-
able for specific development. I shall show presently that even the existing endemic
genera are not all on the same footing.

Comparison of Families with other Regions.

Only 12 families are represented in this portion of the fauna, and two of these,
the Galleriadae and Pyralididae, only by species of undoubtedly artificial introduction ;
thus only lo are truly native, all of them being of world-wide distribution. In the
corresponding portion of the British fauna there are no less than 34 families ; yet all
those families which are represented in Britain by more than 1 2 species are present in
the Hawaiian Islands except the Arctiadae, Sterrhidae, and Notodontidae, and none
which are represented by less ; so that, except for those three families, the results are
in accordance with the law of chance. The New Zealand fauna so much resembles
the Hawaiian in its broad outlines that it may be worth while to compare them in
tabular form.

All the Hawaiian families are therefore found in New Zealand, the Galleriadae
and Pyralididae being introduced in both alike, and 8 other families are also repre-
sented there, but only by a very few species, amounting altogether to 8 per cent, of
the total, or an average of i per cent, each, whilst the ten other native families average
over 9 per cent. each. The single species of Sterrhidae is an abundant Australian
insect, and not improbably artificially introduced thence ; the small size and weak flight
of members of this family may account for their not crossing wide seas. The Noto-
dontidae are absent from both faunas ; they are notoriously seldom seen on the wing,
and may therefore be habitually incapable of prolonged flight.

Geographical Distribution of Genera and Species.

For the consideration of this subject I shall group the genera not by their mutual
affinities but by their constitution, as follows : [a) wholly ' apodemic (none of these
contains more than two species), {b) apodemic, with one endemic species, {c) apodemic,
with from 2 to 6 endemic species, {d) apodemic, with from 9 to 13 endemic species,
{e) apodemic, with 24 to 57 endemic species, [^f) endemic, with i or 2 species, i^g)
endemic, with 14 to 30 species.

{a) Apodemic genera, of one species, or of tnjo species, neither endemic.

There are 17 of this class, comprising 22 species.

Nine [Plodia, Ephestia, Ephestiodes, Meliphora, Euchromius, NytnpJmla, Hymenia,
Hellula, Pyralis), with 1 1 species, have been artificially introduced by man, mostly as
larvae feeding on preserved foods or cultivated plants, and are now apparently estab-
lished as residents ; all of them have similarly extended their range over most of the
warmer regions of the globe (except Ephestiodes, which is hitherto only recorded from
America), so that their place of origin is sometimes unknown, and is in any case
unimportant for the present purpose.

Two {Heliothis, Nomophila), with 2 species, and also Spodoptera exigtia and Sphinx
convolvuli, are practically cosmopolitan, being found in suitable localities almost every-
where, and are further known to be possessed of very great powers of flight, having all
been met with in the open sea, sometimes many hundreds of miles from the nearest
land. These may have come in from any direction, though Sphinx convolvidi is
considered to be the American form {cingidata).

' Endemic denotes that a species or genus is apparently confined to these islands. I define apodemic as
the opposite of endemic ; it signifies that a form occurs outside the islands as well as in them.

17—2

126 FAUNA HAWAIIENSIS

Hypocala, Anosia, Phtsia biloba, and Sphinx celeus, are American insects, all
powerful flyers ; Anosia in particular has within recent memory extended its range over
the whole Pacific to Australia and New Zealand.

Simplicia robustalis, Spodoptera maiiritia, and Plusia chalciies are very wide-
ranging species in S. Asia, the Malay Archipelago, and Australia, the two latter
occurring also in Africa, and the last-named likewise in New Zealand and Europe ; the
two latter are of powerful flight, but the Siviplicia may prove, when its habits are
made known, to be artificially introduced.

This class represents the effect of present-day influences. 1 think it probable that
the 4 cosmopolitan species actually came from America, and in that case there would
be a large preponderance of the American element. Hypocala has a well-marked local
form besides the normal American type, and Hcliothis also shows a tendency to form a
local race, so that these two approach the character of the next class.

{b) Apodemic Genera, ivith one endemic species.

This class includes 7 genera and 1 2 species.

Caradrina is best omitted from consideration ; the single species (in one specimen)
cannot be positively assigned to the genus, which is however widely distributed in the
northern hemisphere.

Cosmopliila is distributed throughout the tropical and subtropical regions of the
world. It is represented by one apodemic species, which occurs also in Fiji, S. Asia,
and Africa, but assumes here the character of a tolerably well-marked geographical
race ; and one endemic species, which may reasonably be regarded as a development of
the foregoing.

Hydriomena is a very large genus of universal distribution, but mainly character-
istic of temperate regions. The single endemic species is not sufficiently near any
other to allow of its affinity being positively stated ; but I am disposed to regard it as
being of an Asiatic (Himalayan and Japanese) type.

Dasyuris consists, so far as is yet definitely known, of one Arctic species (Green-
land, Labrador, Lapland), two Australian, and five from New Zealand. The Hawaiian
species is not particularly close to any of these, though generally similar ; geographically
it is an interesting link. The facts would seem to indicate a New Zealand origin.

Vanessa is represented by three apodemic species and one endemic. Of the
apodemic, V. cardni is cosmopolitan, being perhaps the best traveller of all the Lepido-
ptera, and may have entered from any side ; V. Jninter-a is American, V. atalanta
European and American, but both have probably alike come from America. The
endemic species is intermediate between cardui and atalanta, and its nearest ally is
V. callirrhoe in the Canary Islands ; hence it is probable that both these are the
insular descendants of a former wide-ranging American species, which was also the
ancestor of the continental caj-dui and atalanta.

MACROLEPIDOPTERA 127

Lycaena exhibits one apodemic species, the very widely distributed L. baetica,
which occurs in many Pacific islands, Australia. Asia, Africa, and Europe ; and one
endemic species, by no means very close to any other, but belonging to the group of
L. argiolus (Europe and N. Asia).

Prionopteryx includes at present 7 American species, 2 African, and one Aus-
tralian ; the single Hawaiian species is sufficiently remote from any of these, but
probabilities are much in favour of an American origin.

Summarising these, and excluding ambiguous forms, the apodemic species (present-
day) show 2 Asiatic and 2 American ; the endemic (earlier) indicate 2 Asiatic, i New
Zealand, and 2 American species.

(f) Apodemic genera, with 2 — 6 endemic species.

These number 8 genera, with 29 species.

Hypenodes is a characteristically Indo-Malayan genus, though certain species range
into Europe, Africa, Australia, and New Zealand. Of the five endemic species, one
(much the commonest) is closely allied to the wide-ranging H. costistrigalis ; the other
four are presumably derivatives of this, but are in part rather curiously diverse, showing
sufficient structural modification to permit of subgeneric separation if desired. The
mutual relations of these species are however difficult to understand, and the genus
presents many obscure problems.

Xanthorhoe is a very large and cosmopolitan genus, though relatively more
prominent in New Zealand than elsewhere. The four endemic species are probably
but not obviously of common origin ; they are of an early type, and may have most
affinity to some Australian and New Zealand forms, but it is uncertain.

Deilephila includes one apodemic and four endemic species, one of the latter being
of doubtful generic reference and therefore best neglected for the present. The
apodemic species is the cosmopolitan D. lineata, an insect of exceptionally powerful
flicrht, which micrht have come from either side. The three other endemic species
form a single group, doubtless from a common ancestor, rather markedly distinct from
any other, but perhaps related most to D. galii, which is widely spread in Europe,
C. Asia, and N. America.

Homoeosoma is a generally distributed genus. The two endemic species (extremely
similar but structurally distinct) must be modifications of a single ancestor, and approach
very closely H. vagella, which is very common in Australia, and scarce in New

Zealand.

Talis includes at present 28 Australian species, i New Zealand, 4 Indo-Malayan,
2 African, 3 European, and 2 C. and S. American. The 6 Hawaiian species (probably
there are more to be discovered) form a closely connected group of single origin, which
seem to resemble most the small and inconspicuous Australian T. ge/asiis. though they

128 FAUNA HAWAIIENSIS

show little similarity to the main body of Australian species. It is however also
possible that the connection is with the Indo-Malayan forms. The distribution of this
genus is curious, and it was perhaps once more generally prevalent.

Margaronia is universally distributed in tropical and subtropical regions, but is
most characteristic of the Indo-Malayan fauna. The two endemic species (quite inde-
pendent, and belonging to different groups of the genus) are both of Indo-Malayan
affinity.

Mecyna is a limited but cosmopolitan genus. There are two endemic species, of
which one is the local representative of the universally distributed polygonalis group,
being apparently nearest to the New Zealand form, M. deprivalis ; but here it certainly
appears probable that the New Zealand representative is derived from the Hawaiian
and not vice versa, as it shows no immediate relationship to the Australian form. In
this case the origin of the Hawaiian form must be referred to North America. The
other species is of somewhat uncertain affinity, but may possibly be a derivative of the
first.

Loxostege is characteristic of the northern hemisphere, though stragglers occur as
far as Australia. The three endemic species form a connected group, not very near
to any other, but possibly inclining rather to the North American type.

In this class, therefore, apart from one doubtful and one apodemic cosmopolitan
form, 9 primary species are indicated, of which three are certainly Indo-Malayan,
3 probably American, and 3 probably Australian.

{d) Apodemic genera, with 9 — 1 3 endemic species.

In this class are comprised 4 genera, with 42 species.

Leucania is a large and quite cosmopolitan genus ; some of the species are great
wanderers, and many, perhaps most, of the species feed in the larval state on grasses,
and therefore find suitable food everywhere ; the genus is relatively prominent in New
Zealand. The 9 Hawaiian species belong to two quite independent and dissimilar
groups ; the first 4 species form an endemic group which is rather strikingly distinct
from anything known to me, and must be classed as of wholly unknown origin ; the
apodemic L. tmipuncta is spread over sufficiently warm regions of the whole globe, and
its original home is doubtful ; whilst the remaining 4 endemic species form a connected
group so closely approaching L. tmipuncta that they must be held to have been derived
from it.

Eucyviatoge includes about 20 Australian, Asiatic, and European species. It is
however also interesting as being the undoubted parent of the very extensive genus
Tephroclystis, characteristic of the Northern hemisphere but more especially Europe,
and the also considerable Chloroclystis, which is principally Indo-Malayan, Australian,
and New Zealand. Hence it is relatively a rather old genus, which would seem to

MACROLEPIDOPTERA 129

have been largely replaced throughout its range by its improved descendants. The 10
endemic Hawaiian species form a single group, probably of Asiatic origin.

Omiodes is a genus of moderate extent, spread over the tropical and subtropical
regions of the whole globe. The 13 endemic species form one connected group, in
which the characteristic elongation of the patagia is less marked than usual, and
the type may therefore be regarded as comparatively early. Their origin would seem
to be Asiatic.

Pyrausta is a very large genus, especially characteristic of the Northern hemisphere,
though a certain number of species are found in the Southern. The 10 endemic
species constitute a single group, but two of them show a certain structural modifi-
cation which might be termed subgeneric. In their general character they so much
resemble the species of the allied genus Phlyctaenia, that it seems fair to presume
they are an early type, recalling the common ancestor of Phlyctaenia and Pyrausta ;
and as Phlyctaenia is characteristic of Europe and N. Asia, we may suppose that
they are probably of Asiatic origin.

The features of this class, which must be of a considerable age, agree, so far
as they can be deciphered, in pointing to a predominant Asiatic influence.

(e) Apodemic genera, with 24 — 57 endemic species.

These include 3 genera and 106 species.

Agrotis is a very large and dominant genus of world-wide distribution, but most
largely developed in Northern temperate regions. Two apodemic species occur,
A. saucia being common to Europe and N. America, and A. ypsilon ranging through-
out the Northern hemisphere and extending into the Southern ; the former must
be reckoned American, the latter uncertain. Besides these there are 23 endemic
species, not nearly related to the two already mentioned, but apparently all connected
together ; it is however difficult to affirm this, as change would seem to have taken
place on much the same lines as in other regions, and there is great similarity between
the species of different regions. The Hawaiian species as a whole certainly approach
nearest to those of N. America, some of the forms being so close that at first I thought
they might be identical ; hence it seems very probable that their origin is American.

Phlyctaenia is a large genus, especially characteristic of Europe and N. Asia, but
with a few species elsewhere. There are 24 endemic species, forming a connected
group, whose origin must be esteemed undoubtedly Asiatic.

Scoparia includes, so far as known to me, about 30 European species, 12 Asiatic,
3 African, 3 Madeira, 6 St Helena, 8 N. American, 9 S. American, 24 Australian, and
65 New Zealand. To these must now be added no less than 57 Hawaiian, all endemic,
and undoubtedly all belonging to a single group, presumably traceable to a single
ancestral form. This multiplicity of species is considered by Mr Perkins to be pardy

I30 FAUNA HAWAIIENSIS

due to the very great variety of suitable situations afforded, assuming, as Is most
probably the case, that the larval food consists of lichens. Probably a humid insular
climate is particularly favourable to them, provided it is also sufficiently cool ; the
latter condition can be secured by increased altitude, but a low-lying tropical island
would not be favourable. After making allowance for such local circumstances, how-
ever, there remains an excess of development of the genus in New Zealand and
the Hawaiian Islands, which does not seem explicable merely by favourable conditions.
Early occupation of the ground must have been the other factor in this result, and
probably at something like the same period in both island-groups, and this would
imply a common origin. Now the Hawaiian species are characterised by an unusual
tendency to narrowness of forewings, and by generally showing a few long hairs in
the cell of the hindwings ; both which characters are also repeated in a section of
the New Zealand species, and not in those of any other region. The New Zealand
species as a whole display a much greater variety of size and facies than any others,
and must be regarded as primitive in type and unspecialised. Two or three Australian
species of similar character doubtless claim a New Zealand origin. The Patagonian
S. chordactis, however, and one or two other species from neighbouring portions of
South America, which are undoubtedly closely related to peculiar New Zealand types,
are not so easily explained, but must be classed with the considerable body of other
evidence showing an ancient interchange of fauna and flora between South America
and New Zealand. An elevation of i loo or 1200 fathoms in the bed of the South
Pacific Ocean would be required, to allow of this being easily effected ; it is a large
demand, but cannot be said to be impossible. My present opinion, on the available
evidence, is that Scoparia originated in the New Zealand region, probably at that time
considerably extended. The Hawaiian Islands must then have received their original
species from New Zealand direct, and I should suppose that Christmas Island must
have been on the line of transmission, and would probably still possess allied species
as evidence thereof.

These three genera are then respectively American, Asiatic, and New Zealand.

(_/) Endemic genera, with i or 2 species.

A class comprising 7 genera and 9 species.

Nesamiptis contains two nearly related species ; it is most allied to Uypeiia, which
is extensive and very generally distributed, but apparently approaches especially the
type of some North American species.

Progonostola is almost certainly an endemic derivative of Xanthorkoe.

Sisyrophyta is undoubtedly an offshoot of Scotorythra.

Tritocleis is at present of quite uncertain afiinity, and must be neglected.

Genophanhs is certainly nearest to the monotypic Australian Crocydopora, which

MACROLEPIDOPTERA 131

also occurs in New Zealand. It therefore stands on quite the same footing as
Homoeosoina.

Promylaea is clearly an offshoot of Mestolobes.

Protaulacistis is undoubtedly closely allied to Orthomecyna, but is in some respects
more primitive, and may therefore be regarded as a collateral development.

Excluding the doubtful one, 4 of the above are therefore of native origin, i
Australian, and i American.

(_^) Endemic genera, with 14 — 30 species.

These number 3 genera and 72 species.

Scot oryt lira contains 30 species. It is distinguished from all genera of the
Selidosemidae known to me (except its derivative Sisyrophyta) by the peculiar antennal
character; in other respects it has a general alliance to the cosmopolitan genus
Selidosema, but is of a somewhat more primitive type, and without the characteristic
fovea. It is therefore probably earlier in origin than Selidosema, but I cannot indicate
any nearer relationship with other genera.

Mestolobes includes 28 species, and Orthomecyna 14. They are collateral genera,
obviously nearly allied together, yet with differences which imply that they were derived
not one from the other, but from a common ancestor. They belong to the group of
Scoparia and Heliothela, more especially approaching the latter and Eclipsiodes, but
I consider that they cannot properly be regarded as derived from either of these,
but rather from an earlier ancestral form. The monotypic Malayan Dasyscopa resembles
them in the presence of a subdorsal hairy groove in the hindwings, but appears not-
withstanding to be only an offshoot of Scoparia. Heliothela contains only a very
few species, but is almost cosmopolitan, though with a leaning to the Southern
hemisphere ; Eclipsiodes is Australian.

The origin of the three large endemic genera is therefore unknown. But if,
as inferred above, Scoparia originated in the South Pacific, there is presumptive
evidence for supposing that the other genera collaterally derived from its parent form
must have originated there too ; and the distribution of Heliothela and Eclipsiodes
rather tends to confirm this supposition. If this be granted, why should not Scoto-
rythra, whose origin cannot be traced elsewhere, but may be presumed from its
specific development to date from about the same period, be descended from an
extinct form inhabiting the same region ? For it must be clearly understood that
these large endemic genera could not have originated in the Hawaiian Islands
themselves, for want of possible ancestors ; they must be derived from apodemic
forms, but such as from competition of improved types, or other causes, have not
survived elsewhere.

Arrangement of Genera in order of time.

From a consideration of the foregoing analysis we can now with considerable
probability group the genera under successive periods of time, and indicate the nature
of the geographical influences of each period, beginning with the most ancient.

First Period.

To this belong 7 genera, viz. Sisyrophyta, Scotorythra (Selidosemidae), and
Scoparia, Promylaea, Mestolobes, Orthomecyna, Protaulacistis (Pyraustidae), with 133
species. Probably all these must be traced to a South Pacific origin, and the former
existence of a considerable land-area (now submerged) between New Zealand and
South America is postulated.

Second Period.

Here are referred 5 genera, viz. Agrotis (except 2 species), Eucymatoge, Omiodes,
Pyrausta, and Phlyciaenia, with 80 species. Of these the first only is American in
origin, the other four Asiatic. Possibly this period may coincide in time with the
considerable extension of the Hawaiian Islands to the north-west which seems to have
once existed.

Third Period.

This includes 18 genera and 48 species. Of the genera 6 are probably Australian
or New Zealand in origin [Dasytiris, Progonostola, Xanthorhoe, Homoeosoma, Geno-
phantis, Talis), 5 Asiatic {Hypenodes, Cosmophila, Hydrioniena, Lycaena, Margaronid),
and 5 North American {Nesamiptis, Vanessa (i species), Prionopteryx, Mecyna,
Loxostege), showing a nearly balanced equality of influence which implies circumstances
much as at present. Leucania and Deilephila (4 species) are of doubtful import.

Fourth Period.

This is represented by 29 species, contained in 21 genera, viz. Agrotis (2 species),
Deilephila (i species), Vanessa (3 species), Lycaena (i species), and the 17 genera
recited above as wholly apodemic. Excluding 9 of these genera, which are presumably
of artificial introduction, and 7 other species which are practically cosmopolitan, there
remain only 1 1 species, of which 5 are certainly and 2 probably of American origin,
and 4 presumably Asiatic. The preponderance of the American element (I think a
majority of the cosmopolitan species probably also came from that side) seems to
be explained by the fact that almost all these species possess great powers of flight,
and find little obstacle in mere distance, but are by no means independent of the wind ;
this effect is therefore traceable to the influence of the N.E. Trade-winds.

MA CROLEPIDOPTERA

133

It is to be observed that none of the genera of the first and second periods, except
Agrotis, and only about half the genera of the third period can be esteemed strong
on the wing ; these must therefore in general have proceeded by way of intermediate
islands. Moreover, nearly all the genera of decided American origin, in whatever
period, possess this characteristic of strong flight, and as the trade-winds must always
have existed, there seems no reason to suspect the previous existence of any inter-
mediate islands between Hawaii and N. America.

Inter-Island Distribution of Species.

The following statistics relate only to the 261 endemic species. No doubt further
exploration would extend the inter-island range of some species, but probably new
species of restricted range would be discovered in an equal proportion, so that the
general results may be taken as fairly representative.

Of 4 species taken by Mr Blackburn the localities have not been recorded ; I
suppose 3 to be from Maui and i from Oahu, but they are not included hereafter ; the
total may then be taken as 257.

Of these 173, or more than two-thirds (67 per cent.), are confined each to a
single island. The whole number of species occurring in each island, the number
of peculiar species, and the proportion between the two numbers, are given in the
following table :

Of the remaining 84 species, 36 have been taken both in Hawaii and Kauai, at
opposite ends of the group, and usually in one or more of the intermediate islands ;
they may therefore be counted as ranging throughout the group. The distribution
of the others is as follows :

position at the extremities of the group, since interchange of species proceeds in
their case on one side only, whilst in the intermediate islands it proceeds on both
sides.

There are certain well-marked instances of representative species in the different
islands. Thus in Scoparia there are six species (nos. 7 — 12) which are easily
distinguishable from all the rest by the entire black subterminal fascia, yet also
separated by well-marked characters from one another ; five of these are confined
respectively to the five islands Hawaii, Maui, Molokai, Oahu, and Kauai ; the sixth
is a Kauai species, but differs from all the other five in being yellow instead of white.
Scoparia habnaea is the Kauai representative of S. vieristis. Orthoniecyna alloptila,
chrysophanes, and aibicaudafa are mutually representative in Hawaii, Kauai, and Lanai
respectively. O. exigiia, which occurs in Hawaii, Maui, and Molokai, is represented
in Lanai by O. ctipreipennis, and in Kauai by O. mesochasrna. Scotoiythra aruraea,
from Hawaii, is represented in Oahu by O. caryopis, in Kauai by O. isospora, and
probably in Maui by O. corticea.

On the other hand there are some curious instances of allied species, which might
have been expected to belong to different localities, but which are found occurring side
by side. Such for example are the two species of Sisyrophyta, which are very similar
except in the peculiar secondary sexual characters of the males, the females being
superficially almost indistinguishable ; both of these are common in the same localities
in Hawaii, though it is true that one also occurs in Molokai. So also Scoparia
struthias, triacma, and ciyerodes, which are so similar that I took them at first for
one variable species — perhaps I should add that there is really no doubt of their
distinctness — all occur commonly together in the same locality, and are confined to
the same island. Omiodes demaratalis and monogramma are another very closely

MA CROLEPIDOPTERA

related pair, inhabiting the same localities in Oahu and Kauai. It seems to me
that possibly the comparative slackness of competition in the Hawaiian Islands may
account for this coexistence of two or three similar related forms, of which under
severer conditions one would probably have been improved up to the point of com-
pletely ousting the others, or perhaps the weaker would have been superseded by
a species of a different group.

Characteristics of the Fauna.

{a) Absence of primitive forms.

There are no genera of very early type, such as would help to fill up gaps
between previously known forms. The conditions might probably have been favour-
able for the preservation of such genera, if they had ever reached the islands, but they
do not seem to have reached them. The genera of the first two periods designated
above are early rather than late ; they belong to the earlier half of the Lepidoptera,
but that is all that can be said for them. Perhaps the islands, old as they must
be geologically, are still not old enough for this.

(3) Prevalent close relationship of species.

In those genera where the species are numerous, they are also generally very
difficult to understand. Had the specimens been without locality-labels, I do not think
it would have been possible to have separated the species satisfactorily ; but when
arranged in geographical series, the differences, if any, became apparent. This state
of things would seem to imply that the elimination of species has not been carried so
far as in other regions where there is a sharper competition, which would have tended
to increase the divergence, whilst at the same time destroying the intermediates. The
climax of difficulty is reached in Scotoryt/ii-a, where many of the species are also very
variable, whilst the sexes often differ considerably and are hard to match, and the
secondary sexual characters, which often afford a good distinction in the males, are not
available in the females. It is of course essential that the sexes of these species should
be able to recognise one another with ease, and the visible differences which exist are
sometimes so slight or so little obvious that it hardly seems credible that they can be
appreciated by the insects themselves ; in such cases it would appear necessary to
suppose that the sense of smell has to supply the deficiency. The expansible hair tufts
on the genital organs of almost all Lepidoptera are probably scent-producing structures
connected with this purpose. On the other hand, if the insects themselves do not

136 FAUNA HAWAIIENSIS

appreciate slight visible differences, how are these differences preserved from loss ? It
seems difficult to imagine that the numerous white and black species of the jiicunda
group of Scoparia, which are no doubt well concealed by their colouring amongst the
lichens, derive any advantage in this respect from the slight characters of marking in
which they differ from one another ; and if there were not some influence tending to
the maintenance of these characters, variation in that particular would be unrestricted
and they would disappear. In an ordinary fauna this difficulty does not usually present
itself

(r) Tendency to variability.

An unusual proportion of species show strong variability, which in perhaps 1 5 or
more species becomes excessive. It is impossible to give precise figures on this point,
that would be of any real value, as many of the species only exist in one or two speci-
mens. The variation of such insects as Hypenodes altivolans and Eticymatoge nionti-
colans is quite phenomenal, and the proportion of highly variable forms is certainly
much larger than in an ordinary fauna. In New Zealand, however, highly variable
species of the same character are found in perhaps much the same proportion. Such
species seem to resemble nebulae, which time, or a modification of circumstances, will
break up and condense into groups of stars. I conceive that species in this state of
potential multiplication are more plentiful in thinly stocked regions, such as the
Hawaiian Islands and New Zealand, because the number of unoccupied stations for
species acts as an apparent incentive by removing a real check. In other words,
species are being formed relatively much more frequently in such regions, and therefore
these afford the most favourable opportunity for studying the process. In confirmation
of this view, it may be noted that the 57 species of Scoparia are remarkably constant,
not one being even moderately variable, on the available evidence ; in this genus
specific development has already proceeded so far that suitable stations (assuming
restriction to a lichen-feeding habit) are probably almost all occupied.

{d) Tendency to dull colouring.

It might perhaps be expected that a group of tropical islands, enjoying abundant
sunshine and possessed of a luxuriant vegetation, would be remarkable for the bright
colouring of its Lepidoptera, but the case is quite the reverse. Considered as a whole,
the general effect is exceptionally sombre. This is in some part attributable to the
accidental constitution of the limited fauna, of which the principal genera are such as
are usually inconspicuously coloured in all regions ; thus Agrotis habitually assumes the
obscure tints of the dead leaves and rubbish amongst which the species conceal them-

MACROLEPIDOPTERA 137

selves by day, and Scoparia the mottled black and white, or grey effects of the lichens
which it frequents in all stages. Families, such as the Arctiadae or Zygaenidae, which
are generally brightly coloured, do not happen to occur in the islands at all. But after
making due allowance for these circumstances, it appears that there is a real local
tendency to a dusky suffusion, which often obscures brighter pigments, even when they
are perceptibly present. The best evidence of this is furnished by the local forms of
apodemic species ; thus the local race of Hypocala andremona is so much overspread
with dark suffusion that it has been regarded as a distinct species ; and there is a native
race of Heliothis armigera, in which the suffused dark terminal band of the hindwings
is considerably extended. Margaroiiia cyanomichla belongs to a group of the genus of
which all the other members are sharply and clearly marked with prismatic-white
fasciae, but itself has these markings more or less obscurely suffused with dusky-violet.
Many species of various genera, when examined with a lens, show a not inconsiderable
admixture of crimson, green, yellow, or blue scales, but so combined with other dark
scales that there is little or no appearance of these colours in the general effect ; such
are Hypenodes cyanias, several species of Eucymatoge, Mestolobes, and even Scopai'ia.
It seems to me probable that this tendency is connected with the superabundant
moisture of the climate, and is due to influences exerted in the pupal stage, but it is
sufficient here to call attention to it as an existing fact.

Imitative Colouring.

The question of the assimilation of the colouring of a species to the rocks or plants
which it frequents, can only be adequately treated by the collector, who has seen the
insect amongst its natural surroundings. But there seem to be two or three cases of
apparent mimicry — the assumption by a species of a facies foreign to its own genus but
closely resembling that of an unrelated genus — which require to be noticed here, though
they can only be adequately explained by observations made on the spot. These are as
follows :

Hypenodes epichaka and H. cyanias (although not at all resembling one another)
are so like species of Phlyctaenia in general appearance that at first I had grouped them
with that genus, and was much surprised, on a structural examination, to discover their
true position. There is no exact imitation, but H. epichaka, which is yellow and black,
has a strong general resemblance to Phlyctaenia- chalcophanes, and occurs in the same
locality, and at the same season ; and H. cyanias, which is really partially coloured with
violet-blue but does not show it to the naked eye, is very similar to P. ennychioides,
a dark purplish-fuscous species which is found with it.

Phlyctaenia heterodoxa is quite unlike all its congeners, and has assumed the facies
of Omiodes demaratalis ; the character of the lines and spots has been entirely altered,

138 FAUNA HAWAIIENSIS

the black orbicular dot and straight pale second line being faithfully reproduced. This
species is from Maui, and I have no record of O. demaratalis from that island, yet as it
is one of the commoner species, and is known from Hawaii, Oahu, and Kauai, it does
probably occur in the other islands as well.

In each of these three cases the supposed mimicking species is apparently com-
paratively scarce, and the mimicked one undoubtedly common. But there is at present
no evidence to show that the latter is in any way distasteful or otherwise protected,
without which the proof breaks down ; future collectors are therefore invited to
experiment in this direction. It must be remembered that it is also quite possible that
the members of each pair of similar species are coloured alike merely in similar
adaptation to identical surroundings.

Dorsal scale-projection of forewings.

Finally, I may note that in many of the Pyraustidae there is an unusual tendency
to increased development of the dorsal scale-projection towards the base of the fore-
wings, which is normally inconspicuous. In some species it becomes so prominent
that I at first thought it might be of value as a classificational character ; but finding
that it occurred in various genera, yet was often conspicuous in one and obsolete in
another of closely allied species, I was forced to the conclusion that it was of no
importance as a test of relationship. It is therefore probably an adaptive modification,
depending on external circumstances.

Mr Blackburn, from Mauna Loa, Hawaii, and other localities. An excessively
variable species, differing not only in colour and intensity of marking, but the lines
themselves appear to vary greatly in form owing to the obsolescence of certain
portions and the confluence of others, the first and second lines sometimes appear-
ing almost straight ; the dark spots often look like tufts, but there are no real tufts
as in H. cyanias. The lighter specimens are usually $, the darker $, but this is
not always the case. H. croceipicta Hamps., from Ceylon, approaches it closely,
but seems distinct. The European H. costistrigalis Steph. seems constantly separ-
able by the whitish hindwings, otherwise it does not differ perceptibly from light-
coloured Hawaiian examples. The form exsularis Meyr., occurring in New Zealand
and Australia, has also whitish hindwings, and is therefore distinct from altivolans, but
perhaps identical with costistrigalis.

Varies from light brownish or reddish-ochreous to dark brown ; in one specimen
the median band is wholly deep red-brown mixed with black. Besides the different
character of the subbasal line, the species differs from C. nodivolans in the different
form of the first and second lines, and the larger size.

SCOTORYTHRA Butl.

Face with tuft of scales. Tongue developed. Antennae in t bipectinated, simple
towards base (on 4 or 5 joints above basal) and on apical third. Palpi rough-scaled.
Thorax hairy beneath. Femora sometimes hairy beneath, posterior tibiae in ^ more or
less dilated, containing hair-pencil in groove, posterior tarsi in ^ often reduced. Fore-
wings in Z without fovea; 10 often connected with 9, 11 rarel)' out of 10 very near
base, rarely absent, sometimes anastomosing with 12. Hindwings normal.

Type ^. arboricolans Butl. This genus is endemic ; the species are exceedingly
puzzling, owing to their number, similarity, and similar variability. In the males the
secondary sexual characters, such as the length of the abdomen (measured in terms of
the breadth of the hindwings), the length of the antennal pectinations (estimated in
terms of the breadth of the stalk), and the structure of the posterior legs (the tarsi
being measured in terms of the length of the tibia), often afford valuable aid in their
discrimination ; but the females of allied species are often excessively similar.

In the neuration of the forewings, the origin of i i out of 10 very near base, or its
entire absence, appear to be individual abnormalities, which I have observed only in
one instance of each, of no specific importance ; the connection of 10 with 9 is frequent,
but (as in Selidosema and allied genera) is also of no importance ; the anastomosing of
1 1 with I 2 however is worthy of attention, as 1 have found it in some specimens of all
the first eight species (except corticea, not examined), even in the three monotypic ones,
it being most constant in isospora, whilst I have noticed no instance of it in the rest ; it
therefore helps to confirm the grouping of these species together, though too inconstant
to define them ; these eight species are however distinguished from all the rest by the
form of the second line.

In the following tabulation the scheme is double from the eighteenth heading
onwards, the sexes being thereafter tabulated separately ; this was unavoidable, owing
to the divergence of the sexes in these species ; the discrimination of the males is then
rendered comparatively easy by the use of the secondary sexual characters ; that of the
females is and must remain difficult, the differences between them being extremely
slight, and the individual variability very considerable.

4 specimens ; 3 near Honolulu, Oahu, at 2000 feet ; i Pauoa Valley, Oahu, at 1 500
feet ; in March, April, and October. This species, isospora, aruraea, and probably
corticea, are closely related together, and may be regarded as representative forms of a
common stock, each being confined to a different island. This species is particularly
distinguished by the dorsal approximation of the median and second lines of forewings ;
it is also the smallest in averag-e size.

(4) Scotorythra epicyma, sp. nov.

$. 43 mm. Head and thorax light ferruginous-brown. Antennae pale brownish-

rather elongate-triangular, apex slightly prominent, termen somewhat bowed, little
oblique ; ferruginous-brown, slightly sprinkled with blackish ; first, median, second, and
praesubterminal thick cloudy dark fuscous shades, three former rather near together,
first and second waved, hardly curved, not reaching costa, median and praesub-
terminal almost straight, entire, but latter faint at tornus ; a cloudy dark fuscous
terminal patch beneath apex. Hindwings with termen hardly waved ; colour, median,
second, and praesubterminal shades, connecting blotch, and subapical suffusion as in
forewings.

I specimen, Kaholuamano, Kauai, at 4000 feet, in April. Evidently allied to the
isospora group, but distinguished from them all by the straighter lines, larger size, and
hardly waved termen of hindwings ; the dark suffusion of the markings is probably
variable as in the allied species.

defined dark discal dot before this ; a cloudy rather dark fuscous praesubterminal shade.
Hindwings with termen moderately waved ; colour and markings as in forewings, but
first line absent, median and second lines little curved, more cloudy, praesubterminal
little marked.

Mr Perkins obtained no specimens of this form ; I have described the type in the
British Museum collection, from Haleakala, Maui, at 4000 feet. There should have
been a second specimen in Mr Blackburn's collection, but it seems to have been lost.
The type is a partially deformed female, but there is no doubt of its distinctness from
all others except S. aruraea ; from this it differs only by the more sinuate median and
second lines of the forewings, and apparently separate (though little-defined) discal dot ;
as the two forms are from different islands, and the other most closely allied species are
each apparently confined to a single island, I have thought it best (in the absence of the
male of corticea) to keep them as separate species until further material is available.

of colouring, one being darker than any male, though most are lighter. Closely allied
to 6". isospora, from which it may be distinguished especially by the waved, not dentate,
termen of hindwings ; the average size is larger, the general colouring warmer and
deeper, and the forewings in the $ are without trace of the subapical sinuation,
which is faint yet perceptible in S. isospora ; the posterior tarsi in the $ are relatively
longer.

but instead of being very constant it is very variable ; it differs further in the deeper and
brighter colouring, narrower and more lunate discal spot, and frequently larger size, as
also in the greater proportionate length of the abdomen and posterior tarsi of the male.
The female is best distinguished from the same sex of 6". rai'a by the smaller size, and

2 specimens received by me from Mr Blackburn : locality not indicated, but
not improbably Haleakala, Maui. The white veins and markings of the female
specimen are very possibly not constant. The species is best recognised (except
from S. ortharclia) by the prominent apex of the forewings ; the proportionately
long abdomen of the male, the unspotted shaft of antennae, and the strongly angulated
first line are also notable characters.

9 specimens, Olaa, Hawaii, at 2000 feet, from September to November. This
and the following species are distinguished from all others by the entire waved line
of the grey hindwings, and also by their usually bluish-tinged forewings ; they are
separated from each other by the difference in the first line, which in 6*. ortharcha
is practically straight, in 5. oxypliractis acutely angulated near costa.

on costal third, where it is preceded by a dark shade ; a terminal series of blackish
dots. Hindwings with termen waved ; grey ; an irregularly waved dark grey post-
median line.

lo specimens ; 9 Olaa, Hawaii ; i Hilo, Hawaii ; in January, June, September,

close superficial resemblance leads one to believe, since when carefully considered
they differ in many respects ; the acutely angulated first line is the obvious distinction.

1 2 specimens, Wailuku, Maui, from August to October. Constant ; although
not conspicuous, it is easily recognised by the uniform light reddish-fuscous colouring
and three darker shades ; the posterior tarsi of the male are also unusually short,
though not so short as in 6". bracJiytarsa.

dubious specific relationship ; the unusually broad forewings (especially for a female),
the obsolescence of all lines, and character of the discal spot are the most noticeable
points, but the male may differ considerably in appearance.

The connection of vein 10 with 9 is not here (as in the preceding genus and many
others of the family) the casual and unimportant conjunction at a point of two almost
parallel and closely approximated veins, but 10 is in its lower portion parallel to the
upper wall of cell, and only takes an upward direction after its connection with 9.

^. 20 mm. Head and thorax whitish-ochreous, sprinkled with black. Antennae
ochreous-whitish, pectinations 12, finely black-lined. Abdomen whitish-ochreous, with
double dorsal series of blackish dots, two on basal segment much larger. Forewings
triangular, termen bowed, oblique ; whitish-ochreous, finely and thinly sprinkled with
black ; first line indicated only by a blackish dot near dorsum ; a cloudy dark grey
discal dot ; second line unusually near termen, formed by a series of black dots, running
from |- of costa to f of dorsum, unevenly curved outwards, beneath costa indented

SPHINGIDAE.

Deilephila Ochs.

(i) Deilephila (?) smaragditis, sp. nov.

<?. 94 mm. Head yellowish-green, face and palpi dark purplish-fuscous. Thorax
green, collar and posterior hairs dark purplish-fuscous. Abdomen long, tolerably
cylindrical, green (partly discoloured), on sides and beneath purplish-ochreous.
Forewings rather deep glossy bluish-green ; lines forming very indistinct cloudy darker
yellower-green shades, first absent, median straight, second slightly curved, followed
below middle by a small spot of black irroration, subterminal near and parallel to
second ; a terminal streak of dark purplish-fuscous irroration dilated towards apex
(damaged). Hindwings rather dark purplish-fuscous ; a faintly indicated darker post-
median shade ; cilia yellow-whitish, base dark fuscous. Wings beneath purplish-
ochreous, (Plate V. fig. 7.)

I specimen, Makaweli, Kauai, at 2000 feet, " taken some years ago by ladies of the
Gay family." This example has lost one antenna and the apical half of the other, and
also both posterior legs ; it is therefore impossible to determine properly its generic
position, and it is only provisionally included in Deilephila ; it is superficially very
distinct from anything known to me. It is a remarkable and beautiful species; and its
fair captors might earn additional praise by discovering further specimens, and enabling
its affinities to be accurately ascertained.

(2) Deilephila pyrias, sp. nov.

$ ?. 67 — 74 mm. Head and thorax very dark brown, a lateral stripe on head,
and margins of patagia whitish or yellowish. Antennae dark fuscous, apex whitish.
Abdomen orange, on sides and beneath suffused with crimson, with a broad dark brown
dorsal stripe, and broad dark fuscous or black bands on margin of segments above.
Forewings dark brown, often more or less partially mixed with whitish scales and hairs ;
lines cloudy, dark fuscous, first curved, indistinct, preceded by triangular dark fuscous

or black dorsal blotch, median curved towards costa, often indistinct, second waved,
distinct, followed by trapezoidal dark fuscous or black dorsal blotch ; a suffused dark
fuscous discal spot ; a suffused dark oblique apical streak. Hindwings deep orange; a
suffused irregular-edged dark fuscous basal patch, extending on costa to f ; a straight-
edged dark fuscous or black terminal fascia, attenuated beneath, hardly reaching tornus ;
cilia pale yellowish, base dark fuscous or black. Wings beneath more or less crimson-
suffused. (Plate V. fig. 8.)

II specimens; 9 Olaa, Hawaii, at 2000 feet; 2 Hilo, Hawaii, at 2000 feet; in
January, June, September, November, and December. This and the following species
belong to the section often separated as a distinct genus under the name Choerocampa ;
they are apparently best distinguished from each other by the abdominal colouring.

(3) Deilephila calida Butl.

DeilepJiila calida Butl. Ann. Mag. N. H. (5) vii., 1881, p. 317.

Head brown, with pale yellowish line above eyes. Thorax brown, margins of
patagia pale yellowish. Antennae dark fuscous, tips white. Abdomen dark brown,
beneath pale reddish, three basal segments black on sides except at base which is white,
three apical segments with yellow-whitish basal spot on sides. Forewings fuscous ;
basal area suffused with dark brown, more blackish dorsally, outer edge curved, dorsal
cilia on this area white ; indistinct darker transverse shades towards costa at ^ and f ,
and a roundish dark brown discal spot between these ; second line pale yellowish-
ochreous except towards costa, nearly parallel to termen but sinuate inwards towards
dorsum, followed by a dark brown posteriorly suffused and irregular band, enclosing
a blotch of ground-colour on costa. Hindwings blackish-fuscous ; a rather irregular
vermilion-red postmedian band.

No examples obtained by Mr Perkins ; I have described the type in the British
Museum, from Oahu.

I have not seen this species, but according to the description it should be distinct
from either of the two preceding, though allied to them. The body (abdomen) is said
to be deep brown with a white border on each side. Locality Hawaii.

(5) Deilephila lineata Fab. {livornica Esp.).

5 specimens ; 3 Olaa, Hawaii ; i Kilauea, Hawaii ; i Molokai, at 3000 feet ; in

19 specimens; 17 Kona, Hawaii, at 1500 feet; i Olaa, Hawaii; i Wailuku,
Maui ; from September to December. Tliese examples all belong to the American
and Pacific form, often separated as a species under the name cingulata ; it is how-
ever incapable of strict definition, and I regard it as a slight geographical form
only. The species is practically cosmopolitan.

(2) Sphinx celeus Hiib.

to October. The anterior spot in the black apical area of forewings is rosy in the
male, white in the female. The colouring oi the undersurface of hindwings varies
much ; in the male it is browner, sometimes much ferruginous-suffused, without white
suffusion, but often with sharply defined white discal and costal spots, in the female
it is often much whitish-suffused and with irregular whitish median fascia, but
sometimes very uniform yellow-brownish throughout. The larva is described by
Mr Blackburn, Ent. Mo. Mag. xix. p. 55.

(3) Vanessa cardui Linn.

12 specimens; 6 Halemanu, Kauai, bred; 5 Lanai, at sea level; i Kona, Hawaii,
at 4000 feet; in February, May, and August. Mr Blackburn records it as occurring
in various places in plenty, but apparently irregularly, between February and July (Ent.
Mo. Mag. XVI. p. 161). Some Lanai specimens are very small, one having an expanse
of only 48 mm. A cosmopolitan species.

I Makaweli, Kauai, at 2000 feet ; from February to May, and in August and September.'
The larva is described by Mr Blackburn, Ent. Mo. Mag. xix. 56. Although differing
from all other species of the genus in its light bluish-green unspotted undersurface, this
insect is structurally a true Lycaena, belonging to the group of ai'giolus.

PYRALIDINA.
PHYCITIDAE.

Genophantis Meyr.

Antennae in ^ rather stout, flatly subdentate, shortly ciliated, above base with
a very slight sinuation roughened with scales on inner side; remaining characters
as in ?.

Described originally from the female, and amongst the 24 specimens now sent
there were only two males ; the characters of this sex. as anticipated, confirm the
relationship with Crocydopora.

i%- 17 — 27 mm. Forewings pale ochreous or greyish-ochreous, variably more
or less mixed with ferruginous or reddish-fuscous, sometimes much mixed with blackish ;
in dark-suffused specimens often a pale costal streak, and sometimes an interrupted
broader light dorsal streak, often reduced to a pale dorsal blotch beyond first line ;
first line pale, dark-edged, angulated in middle, on dorsum usually preceded by a
small triangular dark spot ; discal spot usually forming two transversely placed dark
fuscous dots, sometimes obsolete ; second line pale, sufifusedly dark-edged, nearly
straight, parallel to termen, slightly indented above middle. Hindwings pale grey ; a
suffused darker terminal line. (Plate V. fig. 11.)

4000 feet ; 2 Molokai, at 4000 feet ; i Olaa, Hawaii ; i Waianae Mts., Oahu, at 2000
feet ; i Honolulu Mts., Oahu ; from April to June, and in September and October. I
have redescribed the species, as it varies very considerably in colouring, and was
originally described from a single specimen.

Of these three species no specimens were included ; their previous occurrence
is recorded in Trans. Ent. Soc. Lond. 1888, p. 244; they are of course domestic and
artificially introduced, being now probably cosmopolitan.

Ephestiodes Rag.

The separation of this genus from Ephestia is perhaps unnecessary, but may
pass for the present.

33 specimens; 25 Kaholuamano, Kauai, at 4000 feet; 8 Waimea Mts., Kauai, at
4000 feet ; from April to June. Exceedingly similar to the preceding, but constantly
distinguished by the neuration, and also by the well-marked second line of forewings.
It also closely approaches the Australian H. vagella, but may be separated by the
nearly straight first line, which in that species is angulated.

tips whitish. (Plate V. fig. 13.)

I specimen, Waianae Mts., Oahu, at 2000 feet, in April. Distinct by the small
size and peculiar neuration (which varies specifically in this genus) ; in the latter
character it approaches nearest the Australian P. apicistrigella, to which, however,
in other respects it is but little allied.

Maui by Mr Blackburn, from whom I received 24 specimens ; he has described the
larva, Ent. Mo. Mag. xix. 56. This species varies locally, especially in size, and I
found it hard to believe that the extreme forms could be identical, but after prolonged
examination I can find no reliable distinctions. The small rather dull form originally
described is the Oahu form ; the Kona specimens are all medium-sized, lighter-coloured ;
the largest and darkest specimens (mostly purple-tinged) are from Kauai (especially
Mts. Waimea), but transitional specimens from the same localities also occur. The
single Hilo specimen is very purple-tinged, indistinctly marked. Probably these
differences are directly attributable to climatic influences.

No additional specimens obtained. Recorded by Mr Blackburn from Mauna
Lea, Lanai, in September. After careful comparison with allied forms, I consider
that the face is only somewhat prominently rounded and has no true frontal projec-
tion. The first and second lines of forewings are sometimes more distinctly indicated
by dots of blackish scales than is implied in my description, but none of the specimens
are good.

oblique and somewhat marked with black ; dorsal edge sharply black between first and
second lines ; oval orbicular and narrow-reniform discal spot outlined with dark fuscous

4 specimens, Kaholuamano, Kauai, at 4000 feet, in April. The variation in the
structure of vein 10 of forewings is curious but does not impair the generic definition,
though enlarging it ; it appears to be normal in this species, for the four individuals all
differ in this respect, varying from complete separation through partial fusion to stalking
for fully half their length.

probably show differences in respect of the secondary sexual characters of hindwings.

In the preceding tabulation characters are selected which are independent of sex,
so far as possible, since in some species only one sex is known ; but the males of allied
species are sometimes most easily separated by the very well-marked differences in the
secondary sexual characters, viz. the tufts of hair on the hindwings and legs.

ScoPARiA Haw.

I have recently come to the conclusion that Xeroscopa cannot be advan-
tageously maintained as distinct from Scoparia, the point of distinction being so
slight and sometimes hardly appreciable, whilst in other respects, structural and
superficial, there is no difference at all. Probably all the following species show
more or less of the discal hairs characteristic of Xeroscopa. though in some cases
they are apparently reduced to the merest rudiment. All the species have the fore-
wings comparatively narrow, some very narrow.

Xeroscopa pachysema Meyr. Trans. Ent. Soc. Lond. 1888, p. 236.

No specimen of this species was obtained by Mr Perkins ; the locality of the
original type is not recorded, but I should be disposed to conjecture Haleakala,
Maui. It is a peculiar species, not very near any other, markedly narrower-winged
than most others, with the black markings largely developed. The narrowed wings
and dark colouring are somewhat characteristic of Haleakala species, and many of
Mr Blackburn's other insects are from that locality.

No examples of this species were obtained by Mr Perkins ; there is one in
the British Museum, and two in my collection ; Mr Blackburn gives as locality the
mountains near Honolulu, Oahu. Two specimens are mentioned by Butler in the
reference quoted above, but one of these is, I think, a poor example of frigida ;
the other is this species, and now bears a type-label, which it did not in 1888.
Considering this fact, and also that (i) Butler's name is varietal, not specific, being
wrongly identified with angustea {coarctata), (2) there is practically no description
accompanying it, I have therefore not used his name.

one (from Mauna Kea, Hawaii, at 7000 ft.) is this species, but the type (as identified
above) is the other ; the description also clearly indicates the angulated first line
characteristic of the Maui species, but in 1888 I had not recognised their dis-
tinctness.
