AUTHOR'S PREFACE.
Tue present volume, which deals with the Indian Nemarto-
cera,* except the Curronomip# and Cunicip4, is the first one
of the “ Fauna of British India” series devoted to the Diptera,
although this is an order of insects abundantly represented
in every region of the globe, excepting only extreme arctic lati-
tudes and torrid deserts, and even in these latter parts more
species are to be found than might generally be supposed.
Yet the study of Oriental Diptera is quite in its infancy,
less than 3000 species being known from the whole region as:
late as 1896. Since that date certain groups have been revised,
but the material thus treated has, in nearly every case (except
the mosquitos), been drawn from but a limited section of
that zoological region. The Curicip™ is the only family that
has been extensively studied from any considerable number
of localities within the limits of the ‘ Fauna” series.
It would not be unreasonable to estimate the existing
species of the more conspicuous families (such as TaBANIDA,
Bompytiip&, Asitipa, Syrewip#, and the more showy
Muscip#) at not less than double the number of those
already recorded ; whilst in the more obscurely coloured
groups (as, for example, the Cuironomip&, MycrerorHiLip#,
Emrip%, and the more sombre Muscrpa), the existing
species may outnumber the known ones by many times.
The Muscipa are mainly obscurely coloured or else the
species are very difficult to differentiate, which probably
accounts for the general neglect of this family. Yet the
family contains about a third of all known Diptera.
* [The author has used the word Nemocera throughout his manu-
script, but it has seemed advisable to adopt the more correct form,
NEMATOCERA, Which is now more generally used by dipterologists. —Ep. |
val AUTHOR’S PREFACE.
Many new species in the families at present treated of
will with certainty be discovered, but it seems reasonable to
assume that for some little time to come the wants of the
Indian student in the groups monographed herein will be
tolerably well met in these pages.
The bulk of the present material forms an integral part of
the Indian Museum collection, and it is directiy due to my
familiarity with that collection that this volume has been
rendered possible. My thanks are therefore freely tendered
to Dr. Annandale, the indefatigable Superintendent of that
Institution, and to his co-directors, since it has been at his
instigation that I have obtained the necessary knowledge.
My heartfelt thanks are also due to the following gentlemen
who have most kindly suppled me with much valuable
information respecting the types of TipuLip# that are con-
tained in European Museums *:—Dr. A. Handlirsch (Vienna
Museum); Prof. R. Gestro (Genoa Museum); Dr. J. C. de
Meijere (Amsterdam Museum); Mr. Ritsema (Leyden
Museum); Mr. C. Hill (British Museum); Dr. A. Brauer
(Berlin Museum); Mr. Lundbeck (Copenhagen Museum) ;
and Mr. Bedot (Geneva Museum).
To the Directors of the Pusa Agricultural Research
Institute thanks are also due for the loan of specimens for
examination, through the kindness of Mr. F. M. Howlett,
and the gift of a certain number of cotypes for my own
collection; also to Mr. A. D. Imms, of the Muir Central
College, Allahabad, for the loan of specimens which, although
not numerous, comprised a number of new species. Special
thanks are due to Mr. E. E. Green for his untiring energy
in collecting the Diptera of Ceylon and presenting a number
of types of new species to the Indian Museum (as Mr. Howlett
* This information has already been included in a previous paper of
mine (‘ Revision of the Oriental Tipulide,”’ Records of the Indian
Museum, vi, pp. 231-314, 1911), but that paper was practically a basis
for the present more exhaustive work.
AUTHOR’S PREFACE, vii
and Mr. Imms have also done), thus affording me the great
advantage of having practically all the known Indian species
before me simultaneously whilst describing.
A large proportion of the new species have been collected
by Dr. Annandale and Mr. Green, and a considerable number
by Mr. C. Paiva of the Indian Museum. Owing to this fact
the types of six-sevenths of the recorded species have been
under my personal examination, for out of over four hundred
species dealt with in this volume only about sixty have been
described by other authors. The previously recorded species
have been identified by me from descriptions only, except
in a few instances in which my identifications have been
corroborated by comparison with types.
As regards the use of the words “type,”
‘““cotype,” and
so on, there seems no necessity to discuss the various terms
with their exact meanings here, in view of the different
opinions of zoologists on this subject; and more especially
as the simple terms “type’’ and “cotype”’ fulfil all the
requirements in this work. Yet a few remarks to avoid
ambiguity to the student, and that he may at least under-
stand the senses in which the terms are understood by me,
may be pardonable. Personally, when describing a new
species, of which several specimens of each sex are present.
I select one male and one female which, (1) embody the
whole or the buik of the characters of the species, (2) are in
as perfect condition as possible, and (3) from their mounting
allow the best view of all parts of the body.
These two specimens are termed the type male and type
female, and whenever both sexes are present, the type maleis
always the type of the species. Alli other specimens present
before me at the time of describing are termed cotypes. When
only one sex is present, the type specimen may be male or
female. In the event of two species being described under the
impression that the specimens represented the two sexes of a
single species, the name of the species must invariably be
ay
Vill AUTHOR’S PREFACE.
retained for the male, which takes precedence of the female,
and a new name would have to be found for the latter.
It has always been my endeavour to describe the species
and not merely the type specimens, as is too often done.
In proposing the term “ neotype” (or “new ” type) it may
be that an original suggestion is being made, as I am not
aware that it has previously been proposed. It is intended
for use when the original type is lost and a new one is set up,
either from amongst the original cotypes or otherwise ; and
selected either by the author of the species or by a competent
specialist. If selected from cotypes or chosen by the author
of the species from other specimens, a neotype should
practically be of equal value with the original type; but a
neotype set up by any other person than the author might
by some entomologists be ranked as of rather less value.
The only occasion when it has been necessary in this work
to employ the word is in the case of Simulium indicum,
Becher, where I have selected one of the original specimens
from which the description was drawn up, to represent the
type of the species.
There still remains a limited residuum of small, obscure,
or mutilated specimens of Tiputip® and MycrrorHiLipa,
which from their uncertain specific distinctness or un-
satisfactory condition have not been referred to in these pages.
These may be worked out later on with further material. -
In conclusion it is only necessary to say that every care
has been given to make the present work as complete as
possible ; and if I am honoured with the preparation of any
further volumes, I would express the hope that they may be
written in Europe, since, to any one possessed of nerves, the
inconveniences and irritations of India render scientific work
exceedingly difficult.

GL@s:5 A kh Y¥.
Acalyptrata.—One of the two great subdivisions of the Muscrpx, comprising
those species in which the squame are of equal size or nearly so,
or absent. They embrace twenty or more groups which are taxo-
nomically subfamilies only, but on account, of their magnitude are
by some authors regarded as families. See Calyptrata.
Acephala or acephalous larve.—Those in which there is no differentiated
head ; as opposed to the Eucupnana.
Acetabulum.—The minute joint attaching the coxa to the body.
Acroptera.—Brauer’s third division of the OrrHorruarna Bracnycura, con-
sisting only of the Loncnorreripx. Considered by him a super-
family.
Aculeus.—A term used in Hymenoptera to denote the sting of such insects as
bees and wasps, but since no Diptera are aculeate, the term has been
employed by certain of the older authors to define part of the genital
organs. See Stile.
Adminiculum.—Westhoff’s name for the variously structured guard of the
penis in TrruniD™®.
Aerial dancing.—Applied to the habit of many species of Diptera and other
orders of forming small clusters in the air, usually beneath the lower
boughs of trees or over streains, and flying mainly up and down with
considerable swiftness. This habit is somewhat different from that
known as “hovering” (g. v.), and, at least as regards Diptera, seems
to be chiefly confined to the males; moreover, they appear most addicted
tu the practice towards sunset.
Alula.—The anal lobe of the wing proper, and not to be confounded with the
squame, or tegule. Many authors (including myself in my earlier
notes) have erroneously used the term to denote the squame (p. 15).
Ambient vein.—The very fine vein running round the hind margin of the wing
from the end of the costa to the base.
Amphipneustic.—Larve with spiracles on the first and last segments only.
Anal cell,—-The cell behind or posterior to the 5th longitudinal vein when that
is present (p. 14).
Anal vein.—The 6th longitudinal vein, having theoretically in front of it the
anal cell, and posterior to it the axillary cell.
Antennal grooves or fovee.—A longitudinal groove or pair of grooves in the
iniddle of the frons, for the reception of the antenne, bounded on each
side by the facial ridge.
Anterior legs.—The four front legs taken together, the first pair only being
termed the fore or front legs,
b
x GLOSSARY,
Antigeny.—A term sometimes useil to denote sexual dimorphism.
ee \ See Sguame. .
Apex, apical.—The part of an organ, segment, etc., which is most distant from
an imaginary point lying between the thorax and abdomen of an insect,
such as the tip of the abdomen, the last joint of the leg, antenna or
palpus. Opposed to base, basal,
Arista.—The terminal bristle, sometimes very long, on the last joint of the
antenna, Occasionally it is two-jointed, but this is perceptible ouly
under high magnification. It is practically absent in the Orrnor-
ruArHA, though quite general in the Cycrorrmarna. In only one very
small family (the Orrnnerniiipm) of the NemArocnra is there any
approach to it; the antennal flagellum in this group being aristiform.
The arista may be pectinate (7. e. with strong hairs, few in number, on
its upper and lower sides), pubescent, or plumose (when the hairs are
long and placed closely together, forming so to speak a large feather).
In nearly all such cases the hairs are more abundant on the upper-
side. In many groups it is quite bare.
Axillary cell——See pp. 8 and 15,
Avillary vein.—The 7th longitudinal vein, or when the venation is reduced
it is applied to the vein behind the anal vein, but in many cases it is
absent.
Barba, ov beard.—Practically absent in the Numatocera. The long hair on the
lower side of the face and head, conspicuous in the Asinipm; often
joined without interruption to the mystax * or the hair on the cheeks.
The older authors used the term mystax or barba for all the hair on the
head below the level of the antenne.
Base, basal.—Applied to that portion of an organ, segment, ete. which lies
nearest to an imaginary point between the thorax and the abdomen
of an insect ; as opposed to distal, apical, and apex.
Bombylimorpha:—A. superfamily used by Brauer and Bezzi for the Cyrrrinn
(Acroceripz) and Nemesrrinip& together.
Brachycephalous.—Having the head wider than it is long.
Callus, calli.—More or less distinct swellings on various parts of the body,
generally on the thorax; in some families (especially in TaBanip®) on
the frons or vertex. (See p. 5.)
Calypter, calyptron,—See Squane ; also p. 16, note.
Calyptrata.—A division of the great family Muscip™, embracing about. half
the known species, including all those in which the squame are large,
easily visible, and distinctly different in size; as opposed to the
ACALYPTRATA, in which they are very small, practically equal in size
(the upper and lower scale), or absent. The Catyprrara comprise
the Tacninin (including the Drexrnna and SarcoruaAgine), Muscixe
and Antnomyinm®. See Acalyptrata.
Cells.—For full description, see pp. 8 and 13.
* Literally, moustache.
GLOSSARY,
Central vesicle ov vesicula centralis,—Vhe large bulbous basal portion of the
penis in Trevi»,
Cephalic.—Appertaining to the head.
Chetotary.—The arrangement of the prominent spines and strong bristles
present on various parts of the body in many groups of Diptera. They
are very valuable classificatory characters, and are named in accord-
ance with the parts of the body on which they are placed, cephalic,
thoracic, abdominal, and so on. ‘Those on the sides of the thorax
are known as pleural bristles, whilst most of the well-defined and
constant ones on other parts of the body have their special names.
As, however, none of the Numarocera possess bristles of chstotactic
magnitude it is unnecessary to describe them in full here. They
reach their maximum probably both in size and importance in the
Asinip& and Muscipz.
Cheeks, or gene.—The sides of the lower part of the head below the eyes
and on each side of the mouth.
Chitine—The substance of which the hard parts of the outer covering of
insects is composed.
Cinereous.—A light grey colour, but not so pale as ash-grey. Ridgway *
illustrates it as too dark, to my thinking; his No. 6 “ orey” being
more my own opinion of the term.
Claws.—See Ungues.
Clypeus.—This is probably present only in those Diptera with highly developed
mouth-parts. It is an upper transverse piece, and most obvious in such
groups as the TaBanip®.
Coarctate.—A term used to designate those pups of insects in which the future
parts are unrecognizable from the exterior surface.
Cocoon.—The outer covering of silk, or similar substance, formed by the larvee
of many insects, in which they pass the pupa state.
Collare.—Osten Sacken’s term for the disc-shaped prothorax in many
TirvLip».
Collum.—The neck.
Costa.—Technically, the entire marginal vein of the wing from base to base, but
usually employed im Diptera to denote the anterior margin only from
the base to the extreme tip. In some genera this vein, the costal,
actually terminates somewhere near the wing-tip, its place then being
taken by the ambient vein for the remainder of the marginal distance.
Costal cell.—The cell immediately below the costa or costal vein. See
pp. 8 and 13.
Cotyloid cavity.—The opening in the thorax of insects which receives the
head of the first joint of the leg, namely, the acetabulum, or if this
be absent, the coxa.
Cova.—The first easily seen joint of the legs, but it is actually attached to
the thorax by a very minute joint known as the acetabulum. The
cox are very greatly developed in many groups of Diptera, notably
in some of the Mycrropniiip® amongst the Numarocrra.

Xii GLOSSARY.
Cross-veins.—Veins perpendicular, more or less, to the longitudinal axis of the
wings. ‘They are termed the humeral, subcostal, marginal, anterior,
posterior, and discal; whilst in one subfamily of TipuLip™ is found
a special cross-vein which I have designated the costal.
Cubital vein.—A name applied by the older authors to the 3rd longitudinal
vein,
Cyelocera.—Schiner’s and Brauer's term for the Noracanrua and TanysToma
taken together.
Dermatina.— Eremochetous species in the sense that there are no strong
bristles on any part of the thorax or scutellum” (Verrall). Verrall’s
name for the Scenorrnips and Mypaip™ taken together.
Dichoptic.—Applied to the head when the eyes in the male are separated by
a distinct more or less broad frons ; as opposed to holoptic.
Discal cell.—-The conspicuous cell near the centre of the wing in a large
number of Diptera (p. 8).
Discal vein.—Some of the older authors spoke of the 4th longitudinal vein
under this term.
Distad.—Away from, the body or the base of any part; as opposed to
proximad.
Distal.—Nearer the outer extremity than to the body or to the base of any
organ.
Divaricate.—Applied to the habit of some insects of resting with the wings
(and often the legs also) stretched out flat on the surface of the
object ; as opposed to those which fold the wings over the abdomen
when at rest. Used by many authors in writing on Tirunipe.
Diverticulum.—The sucking stomach in Diptera.
Dolichocephalous.—When the head is longer than it is wide.
Empodium.—‘‘ A. median appendage on the underside of and between the
claws, either in the form of a pad, like the pulvilli, when it is called
pulvilliform, or like a bristle or spine; rarely it is alone present and
the pulvilli wanting” (Williston).
Energopoda,—A. superfamily. ‘‘Chatophorous species in the sense that there
are strong and usually numerous bristles on the scutellum and legs;
or at least on the sides of the mesonotuin ; except in the few cases
in which dense coarse pubescence is substituted” (Verrall). Verrall’s
name for the Arroceripm and Asitip®. Osten Sacken also included
Douicnorip#, Eupip®, and Loncnoprertp®, and was inclined to admit
also PuoripD® into the same group.
Epipharynx.—A narrow piece lying immediately below the labrum or upper
lip in those kinds of Diptera with a highly developed mouth. Be-
tween these two parts, which form a long tube, the insect sucks up
moisture from flowers, the blood of animals, or other sustenance.
Epistoma, epistome.—The mouth-opening and its immediate vicinity: often
used by the older authors to signify practically all the lower part of
the head below the eyes, except the palpi and any specially developed
part of the proboscis.
GLOSSARY, xili
Eremocheia.—A superfamily in which Osten Sacken included the Srrario-
MYID& (with Xytomyrn«), TaBantp.s, AcaNTHoMERID®, and Luprip:
(with XynornAgmym and Ca@yomytn). Verrall adds to these the
Nemestrinip and Cyrripa.
Eremochetous——A term applied to those Diptera absolutely without any
strong bristles on the head or thorax, as distinct from ordinary
pubescence or such as the bristly hairs in Psycuop1p®,
Eucephala.—Those larve possessing a distinct head; as opposed to the
ACEPHIALA,
Extricate.—Applied to pupx in which, from their mummy-like facies, the
outlines of the future imago are more or less distinctly seen.
Face, facies.—The term j/ace is restricted to that part of the front of the
head below the antennz and enclosed by the cheeks and the upper
margin of the mouth. In many cases a well-defined line, ridge or
bend in the surface distinctly delimits the face; at other times the
limits are formed by imaginary lines drawn between the points
specified. acies literally means the face proper, as above described,
but is never used in that sense, being employed to signify the general
appearance of the whole insect.
Facial ridge.—The sides of the antennal fovex.
Fascia,—A transverse mark which is more or less irregular in outline,
generally with ill-defined edges.
Feet—Some of the older authors, as late even as Walker and (sometimes)
Osten Sacken, used this term to signify the whole of the legs, but it
should strictly be applied to the appendages of the last tarsal joint.
The feet of Diptera consist of (1) two wagues or claws (movable curved
opposable hooks), (2) the pulvil/, or two pad-like fleshy cushions, and
(3) the empodiuwm, a median appendage varying in form from an
additional pad to a spiny process. Sometimes the empodium is
pulvilliform, occasionally the pulvilli are absent, or modified.
Femur.—The first conspicuous long joint of the legs, nearly always the
strongest of all; preceded by the coxa and the very small connecting
joint between these two called the trochanter, and followed by the
tibia.
Ferruginous.—-A reddish brown with more or less of a yellowish tinge; rust-
colour. Walker describes the word as ‘‘ rusty yellow.” Ridgway gives
it as ‘‘ light burnt sienna.”
Flagellum.—tThe joints of the antenn after the basal two (which latter are
known as the scape). In the Nemarocrra they are nearly always
differently shaped from the scapal joints, and very variable in form
(pieZl):
Forceps—The term employed by Osten Sacken and some others for the male
genitalia in such families in which they are conspicuous, complex and
formed mainly of a pair of distinct claspers to which various appendages
are attached.
Fovea, fovee.—See Antennal groove.
Frenulum.—A name suggested by Loew for what is generally known as the
seutellar ridge.
X1V GLOSSARY.
Frons, ov Jront.—The space that lies between the eyes (viewed from in front),
limited above and below respectively by the vertex and a line drawn
through the rvots of the antenne. The demarcation between the vertex
and the frons may be sharply defined by a sudden angle in the surface,
a difference of colour, or there may be no line of distinct separation.
In Libio, for instance, the vertex and frons are practically united and
inseparable owing to the flatness of the head.
Frontal lunule,—A crescent-shaped or oval space immediately above the base
of the antennee, between them and the transverse slight depression
known as the frontal suture. This lunule is frequently indistinct,
probably often quite absent, although its presence is the only technical
means, according to Braner, of determining in the imago state whether
a given individual belongs to the Cyctorruarma. It is prominent in
the Muscip#, but indistinct or absent in the other three families of the
Cycnorrmarua, viz., Syreurs, Prruncunips, and Praryrrzipe,*
though Verrall thinks it traceable in certain peculiarities in the
structure of the head in these three families.
Frontal suture.—An impressed line, or very shallow narrow groove of crescent,
shape enclosing the frontal triangle or frontal lunule. Theoretically
present in all Cyclorrhaphie flies, but inconspicuous or absent in three
families out of the five. Skuse calls it the frontal fissure.
Frontal triangle.—The small triangle (with the apex upwards) immediately
' above the base of the antenna, caused by the divergence of the eyes
from one another below their region of contiguity. It therefore can
only occur in holoptic or sub-holoptie Diptera.
Fulvous.—Golden yellow.
Gene —The cheeks (q. v.)
Genitalia.—Vhe organs of generation. In the male they are technically known
as the hypopygium, in the female as the ovipositor.
Glabrous.—Osten Sacken uses this term to define bare eyes in Tipunipx. It
is also used in connection with descriptions of wings, meaning smvoth
and shining.
Gonapophyses.—‘* Four free rods that arise from the wall of the genital
chamber, two above and two below the base of the penis, and project.
backward within the chamber ” (Snodgrass).
Halteres.—The ‘ poisers”” of the older school of authors, and “ balanciers” of
French writers. The atrophied hinder wings in Diptera, reduced to a
narrow short stem with a more or less distinct club at the tip. They
are placed behind and below the wing, one on each side of the thorax,
Hemicephalous.—A term used by Dufour and others for those Dipterous larvee
in which the head is not sufficiently differentiated to include them in
the Evucrruana, yet sufficiently obvious to withdraw them from the
ACEPHALA,.
* Technically it snould be present in these families also, if Brauer’s theory
be accepted, and its absence seems to weaken considerably its value as a
taxonomic character.
GLOSSARY. XV
Heterodactyla.—-The second of the two divisions into which Brauer divides his
PratyapyyA, which latter is the first division of his Orrmorrimarita
Bracnycera.
Holoptice.—Used of the head when the eyes are contiguous; opposed to
dichoptic. Generally a character of the male sex only, but exceptions
occur in several families.
Homeodactyla.—One of the two divisions into which Brauer divides his
Puaryernya. See Heterodactyla.
Hovering.—This term expresses the habit of some flies of remaining quite
stationary in the air, then suddenly darting away a short distance and
again remaining stationary.
Humerus.—Vhe shoulder or anterior corner of the thoracic dorsum; when it
takes the form of a more or less distinct bump it is known as the
humeral callus.
Hypocera.—The name given to a superfamily consisting only of the Puoriw.».
Hypopleura.—The pleural area between the metapleura and the hind coxz.
Hypopygium.—The male genital apparatus as a whole, as distinct from that of
the female.
Imaginal disks.—Centres of the formative tissue in the larvae of certain insects
especially Diptera, which give rise to the legs, wings, ete.
Intercalary veins (Lioew).—The lower prongs of the upper and lower branches
respectively of the 4th longitudinal vein (p. 12). The term has been
used by subsequent authors for various veins, but without obtaining
general acceptance.
Johnston's orgav.—A minute structure in the 2nd antennal joint of Diptera
which is supposed to contain the auditory nerves.
Labella.—A pair of organs, generally more or less oval or rounded, nearly
always at the tip (occasionally at the middle) of the proboscis.
Labiwm.—The lower lip. In Diptera always the lowest part of the proboscis,
and constructed, in the most highly developed forms, more or less like
a groove or case in which the remaining parts can be folded and covered
by the labrum,
Labrum.—The upper lip, the uppermost part of the proboscis in Diptera.
Lamella, lamelle.—Small leaf-shaped extremities to the ovipositor in the
female. A general term also for an oval or leaf-shaped flattened
terminal or projecting process.
Lamella basalis supera and lamella basalis infera.—Westhoft’s names for the
upper and lower sides respectively of the 8th abdominal segment. He
terms the upper and lower sides of the 9th segment (namely, those
actually forming the genitalia) Jamelia terminalis supera and infera, but
the terms have not been adopted by other authors.
Macrochete.—The large strong bristles in Diptera distributed over various
parts of the body, which are constant and possess a very high taxonomic
value. The study of this subject is termed Chetotaxy.
Marginal cell.
Mediastinal cell, { 5° Pp- 8 and 18.
XVi GLOSSARY.
Mediastinal vein,—Ideutieal with the auxiliary vein, that is to say, the first
vein below the costa; also known as the subcostal yein, but some
authors (including Verrall) employ the term subcostal for the Ist
longitudinal vein. This appears illogical to the present author, since
the very name subcostal suggests a position immediately beneath the
costa. .
Mesopleura.—The pleural area immediately in front of and slightly below the
roots of the wings.
Metanotum.—The hindermost portion of the thorax, situated directly below
the scutellum, highly developed in some families of Numarocnra,
especially the ‘Yreunip2.
Metapleura.—The pleural area immediately behind and slightly below the
root of the wings.
Metapneustic.—Used of larvee in which the spiracles are confined to the
posterior segments only.
Metatarsus.—The Ist joint of the tarsus, that is to say the one adjoining the
tibia, the following joint of the tarsus being the second.
Microchete.—The smaller bristles in Diptera, distinct from pubescence or
hairs, but not of sufficient size or importance to rank as macrocheetze,
and therefore of much less taxonomic value.
Microphona.—Verrall’s name for the Emrr® and Doricnoriw..
Mystax.—The “moustache” ; strictly applied to the long hairs on the cheeks ;
seldom, if ever, present in the Nemarocrra, most conspicuous in the
very pubescent groups of Bracnycura, such as Astnip£, Bompyiiip.,
ete. See Barba.
Neuration.—The older authors’ name for venation.
Niie blue or Nile green.—A somewhat pale shade intermediate between blue
and green.
Notacantha,—Brauer’s term, used by other authors also, for the SrraTionyip”,
“ XYLOPHAGIDE”’ (regarded erronously as a family) and Cayomyipx. A
superfamily, in the view of such authors.
Nyiph.—The name applied to the pupa when it is active and not fixed.
Obtecte.—Applied to those pupx that shew no sign of the shape of the future
imago.
Occiput.—The hinder surface of the head.
Ocellar triangle and ocelli.—The simple eyes in Diptera (or other insects) are
placed on a triangular spot on the vertex of the head, which is generally
elevated (sometimes considerably so) above the surface, called the
ocellar triangle, the ocelli being placed at each corner of it, when there
are three. Sometimes there are two only, sometimes they are absent,
but in no instance are there more than three. In some families they
are well separated (Mycrropninip®), when they are placed directly on
the frons, in the form of a more or less flattened triangle, cr in an
absolutely straight line. As a rule they are very constant characters
when present.
Ochraceous.— Of the colour of brown ochre with an admixture of yellow.
Orbit.—The margins of the large compound eyes, whether such are distin-
GLOSSARY. xVvil
guished by a distinct ring, ridge, or well defined space, or not. The
frontal orbit is that part of the orbit immediately abutting on the frons.
O thocera.—Schiner’s and Brauer’s name for the BomByLimorpiaA, PRocEPiALa,
and Poryroma. Schiner, however, includes Leptip® in the Orrmocera,
Orthogenya.—Brauer’s second division of his Ortuorruarina Braciycera,
composed only of Empipx® and Doricnorips.
Ovate.—Egg-shaped, that is, an ellipse more pointed at one end than the
other.
Oviposition —The act of depositing eggs by the female.
Ovipositer.—The female genital organs, as distinguished from those of the
male.
Palpi, palpus.—These organs in the Diptera possess from one to five segments ;
the vast majority of Brachycerous flies having only one segment, and
the Numarocera four. In many groups they are rudimentary, in
others absent (p. 19).
Pectinate.—When the vestiture of the antenne is stronger than stiff pubescence
or verticillate hairs and takes the form of stiff bristles, or branched
pendulous or yariously formed solid projections, they are termed
pectinate.
Pectus.—The breast. Walker used it to denote the lower anterior part of the
thorax. Modern authors do not, I believe, employ the term.
Peripneustic.
head- and tail-ends, are so called.
Peristoma, ov peristome.—Apparently a synonym of epistoma,
Piceous.—Blackish brown ; pitch colour.
Pile.—A very closely set and very short pubescence of erect hairs resembling
Larve with spiracles on the median segments, as well as at the
the ‘‘ pile” of velvet.
Platygenya.—Brauer's first division of the Orrnorrmarua Braciycera, com-
prising all the families except the Emr1rp%, Doricuorip®, and Loncnor-
TPRIDE.
Pleure.—The sides of the thorax are in many Diptera separated into fairly
distinct divisions by two sutures running longitudinally to the axis of
the body, and by one perpendicular or transverse suture. The upper
suture is the dorsoplewral (or more correctly notopleural); the lower
longitudinal suture is the sternopleural. The vertical suture (though it
is seldom either straight or absolutely vertical) is the mesopleural. The
pleurz (or spaces) are named the proplewra (or prethorax), mesopleura,
and pteropleura, the two latter divided from each other by the meso-
thoracie suture. Below the sternopleural suture are, the séernopleura (in
front) and the kypoplewra (above the middle and hind cox). The meta-
pleura is a more or less indistinct space behind the pteropleura and
hypopleura, and adjacent to the metanotum.
Plumbeous.—Leaden colour, which may be dull or shining.
Poisers, or balancers.—The older authors’ terms for the halteres.
Pollinose.—An expression used to define a surface with a light dust-like
covering, resembling pollen; a finer vestiture even than tomentum.
Polytoma.—Brauer’s (and Bezzi's) name for a superfamily consisting of the
THEREVIDA and SCENOPINID®.
XVill GLOSSARY.
Porrect.,—Projecting straight forwards ; applied to antenne or palpi.
Post-alar callus.—A more or less distinct, rounded swelling situated between
the root of the wing and the scutellum, often inconspicuous or absent.
Posterior legs.—The hindermost four taken together, the last pair only being
termed the hind legs.
Postical vein.—The 5th longitudinal vein.
Prefurca.-—The portion of the 2nd longitudinal vein lying between its origin
and its forking. ‘This is the sense in which Osten Sacken employs the
term and in which it is used in the present volume, but Verrall uses it
in the Bracnycera to denote “ the common origin of the 2nd and 3rd
veins,” in other words for only that portion of the 2nd vein between its
origin and the origin of the 35rd vein,
Pre-alar callus —A more or less distinct, rounded swelling in front of the
root of the wing, on the side of the mesonotum, just behind the outer
ends of the transverse suture.
Pre-sutural depression.—A quite small depression, generally triargular in
shape, situated at each end of the transverse thoracic suture, close to
the commencement of the dorsopleural (notopleural) suture.
Procephala,-Brauer’s name for the superfamily containing the Mypaipx,
Asiiip® and Bompyniuipe ; Bezzi also adopts it.
Propygium.—Bergroth’s name for the hypopygium.
Prothorax.—The anterior part of the thorax, in Diptera often indistinetly
marked off from the main middle part or mesonotum.
Proximal.—Nearer to the body of the insect, the base of a wing or leg, and
so on; as opposed to distal, distad. Proximad is the corresponding
adverb.
Pscudotrachee.—Radiating ridges on the inner opposable sides of the
labella in many Diptera, which ‘‘serve as a means of attrition, by
which the insect rubs off particles of food from firm substances ”
(Williston).
Pteropleura.—Vhe pleural area immediately below the root of the wings.
Ptilinum—A small but powerful bladder-like organ, present in the
Cycnorruaria only, situated just above the base of the antennz on the
frons. It is only used by the insect to escape from the puparium, by
inflating it, upon which it protudes through the frontal suture and
springs off the cap of the puparium,
Pubescence.—The clothing of soft hairs common to nearly all Diptera in
different degrees, not short or dense enough to be known as pile, nor
containing bristles.
Pulvilli—* Two pad-like fleshy cushions attached to the last joint of the tarsus
below the claws, usually present, but often absent among the
Ortnorrmarna, and often much larger and better developed in the ¢
than the Q” (Williston).
Puncture.—A winute indentation of the surface.
Radical cell—A term used by a few of the older authors for the basal
cells.
Rhomboidal cell—A small four-sided cell near the end of the costa in
Tirunips. At first Osten Sacken called it the trapezoidal cell.
GLOSSARY. x1x
Rostrum, or snout.—The usual, more or less cylindrical, anterior prolongation
of the head that projects over the proboscis proper, most conspicuous
(amongst the Numarocera) in Treutins., Probably some of the older
authors used the teri to include both the rostrum proper and the
proboscis also.
Scape, or scapus.—The first two (or basal) joints of the antenne, nearly always
differentiated from the rest. In the Nemarocura, the 2nd joint is
generally much shorter than the Ist, and the Ist joint of the flagellum
(i. e., the remaining joints taken together) is usually longer than the
others. The scape is in nearly all cases sufficiently obvious.
Scutellar ridge.—A sometimes very conspicuous hardened ridge joining the
sides of the scutellum to the thorax. Often inconspicuous or absent.
Loew has suggested for it the name “ frenulum.”
Scutellum.—The semicircular or crescent-shaped small piece affixed to the
hinder margin of the thoracic dorsum. It often bears important bristles
or spines, though less frequently so in the Newarocera than in some
other groups.
Seta.—Applied to a somewhat long bristle-like hair. It is also used to
designate the microscopic stiff hairs with which many wings are covered,
and which are invisible to the naked eye.
- Setigerous.—Provided with seta.
Spurious cell.—See p. 15.
Squame.—The most correct term for the scale-like organs (one covering
the other, either equal in size or the lower one much larger than the
upper) found at the root of the wings in the higher Diptera. The
upper or anterior one is fixed to the base of the wing behind the alula
and is most correctly termed the alar sguaima or squama alaris; the
hinder or posterior one, whieh in all the higher groups of Muscrp# and
other families is always much larger than its companion, is attached to
the thorax and is therefore most correctly called the thoracic squama or
squama thoracis or thoracicalis. The presence or absence of these organs
gives the distinguishing names of Canyrrrata and Acatyprrara, dividing
the Muscrp © (sensu lato) into two great groups, above subfamilies and
approximately of equal extent. The line of demarcation, however, is
not absolute, many small Anrnomyip& having squamz of equal size and
very little larger than those found in the AcaLyprrara, in which group,
moreover, exceptions with squamez of comparatively large size are found.
Some authors call them tegulx, calypters, or (erroneously) alulzx.
Sternopleura—The pleural area forming the lowest part of the ventral surface
of the thorax, developed chiefly between the fore and middle pair of
legs.
Sternum.—The lower surface of the thorax.
Sternites—The plates on the lower surface on the body of an insect, but here
specially used to denote the ventral plates of the abdominal segments,
the numbers of which are counted from the base outwards; opposed to
tergite.
Stigma.—This is used in two distinet senses: (i) In the wings of many Diptera
is a more or less clearly defined, darkened (generally yellowish, brown
xX GLOSSARY.
or black) spot of oval or some such shape, towards the costal margin, a
little or considerably beyond the middle of the wing, bounded usually by
the auxiliary and Ist longitudinal veins. Thisis the stigma in the most
ordinary sense of the word, as used by systematists. (ii) Four very
small apertures, easily overlooked, generally situated each at the bottom
of a small pit, are termed the prothoracie and metathoracic stigmata
respectively. The former are placed, one on each side, below the
shoulders towards the front; the latter, immediately in front of the
halteres. The prothoracic stigma is by some called the mexothoracic.
These stigmata or spiracles serye for the admission of air to the
respiratory system,
Style.—Used in two senses: (i) The elongate, conical, blunt or pointed solid
appendix to the ultimate joint of the antennx, as opposed to the arista
(g. v.). (ii) Osten Sacken’s name for ‘a single inmovable styliform
organ,” visible immediately below the genital organs in Liwnositnr. Not
seen in other groups in the same form, but replaced by the aculeus, “a
slender, horny, often curved and pointed piece, which is entirely
concealed when the forceps is closed and projected when it is open”
(Osten Sacken).
Subapical cell.
Subcostal cell.
Subcostal vein.—Strictly, the vein below the costa, which in the present work
is called the auxiliary vein (after Osten Sacken and many recent
authors). Verrall and some others apply the term tothe Ist longitudinal
vein.
Submarginal cell.—-See pp. 8 and 13.
Supra-alar groove-—A groove on the mesothorax just above the base of the
wing, short and often indistinct. In bristly species, important bristles
are often situated there.
Suture.—A general term for an impressed line. The principal sutures are the
transverse (p. 5), on the thoracic dorsum, and the pleural (p. 5), on the
sides of the thorax.
| See pp. 8 and 13.
Tanystoma.—Brauer’s superfamily name, adopted also by various other
authors, for the TABANID& and Leprrip x.
Tarsus.—The third and ultimate of the conspicuous divisions of the legs,
always of five distinct though often closely applied joints, of which the
first is called the metatarsus, the next is the 2nd, and so on, the 5th
bearing the feet.
Tawny.—A pale brownish yellow colour varying in intensity, approximately of
the colour of a lion.
Tegule.—See Squame.
Tergite-—The plates, or sclerites, on the upper surface of an insect ; here more
especially applied to the upper half of an abdominal segment, these
being numbered in rotation, beginning with that one nearest the
thorax.
Tergum.—The upper surface of an insect.
Testaceous.—Technically brick-red, according to handbooks on colour, but my
personal opinion is that most authors have used it for what may be
better described as ‘‘ reddish yeilow.”
GLOSSARY, XX1
Tibie.—The second of the large conspicuous divisions of the legs, generally
longer and thinner than the femora, and normally longer than the tarsi.
In some families and genera one or two spurs or spines at the extreme
tip furnish valuable characters in classification.
Tomentum.—A. vestiture of exceedingly short, semi-erect hairs, finer and shorter
than those known as “pile.” Williston says that tomentum can only
correctly be used to desiginate ‘flattened, scale-like or stubble-like,
more or less recumbent hairs which gradually merge into dust or
pollen.”
Transverse.—At right angles to the longitudinal axis of the body, such as the
transverse suture on the thorax; or to the length of the wing, such as
the “ cross-veins.” When applied to the head or proboscis it means
broader than long.
Transverse suture.—See Suture.
Transverse veins —See Cross-veins.
Trapezoidal cell.—See Rhomboidai cell.
Trochanter.—A small, generally annular joint uniting the coxa to the
femur.
Tromoptera.—Osten Sacken’s superfamily for the Newesrrinips, Cyrtipe,
Bomsyiup#, THEREVIDE and Scexoriip#. Verrall confines it to the
Bompyiiip# and THEREVID&.
Truncate.— Ending abruptly, as if cut off.
Ungues.—The claws, two in number, affixed to the lower side of the 5th (ter-
minal) tarsal joint. The remaining portions of the feet consist generally
of the pulvilli and the empodium.
Vena spuria.—Only present in the Syrpnipx, a family of the Bracnycura.
It runs in front of the 4th longitudinal vein and is merely a fold or
crease in the wing and not a true vein. It is sometimes indistinct but
invariably present in this family except in the genus Graptomyza.
Venation.—The system of the veins in the wings. The older dipterologists
spoke of it as the mewration, a synonymous term used in other
orders.
Ventriculum.—The true stomach in Diptera, as distinguished from the
diverticulum or sucking stomach.
Vertex.—The upper part of the head, lying between the upper angles of the
eyes, merging in front more or less abruptly into the frons (g. v.). An
imaginary line between it and the back of the head (or occiput) is called
the vertical margin.
Vertical margin.—The marginal line between the vertex and the occiput.
Vertical triangle.—The small, often extremely small, space in holoptis flies
between the absolute vertex and the spot where the eyes first touch each
other. It bears the ocellar triangle (when such is distinet), which in
its turn carries the ocelli, when these latter are present,
Verticillate.—W hen the joints of the antennz are provided with verticels.
Verticel, or verticil.—A whorl of hairs arranged around an antennal joint in the
form of a circle. Two or more such whorls may be present on the same
joint.
Xxil GLOSSARY.
Vestiture.—The outer adornment of the surface of the body, which generally
takes the form of short hairs, yet every variety and intermediate grade
from strong spines to the finest dust may be found. Large spines,
isolated and regularly placed, or numercus and irregularly placed, are
spoken of as such. Bristles, the position of which is constant in
the genus or species are referred to as chatotactic bristles, and are
most valuable adjuncts in classification; they are named according to
their situation on the body (see Chetotazy). Irregularly placed bristly
hairs (such as are met with in abundance in Psycnoprpm) have no
technical term, Finer vestiture is known as hair, if comparatively long
and in any way coarse, shaggy or woolly; if fairly short and fine, it is
known as pubescence, and this is the commonest form of all. Very short
erect closely set hair is known as pé/e; a shorter vestiture still is called
tomentum ; after which the finest form recognised is termed dust, or the
surface is said to be pollinose.
Vinaceous.—The colour of light claret.
Vitta.—A short longitudinal stripe or mark.

Orver DIPTERA.
Apart from the males of the Coccrp#,. or scale-insects, the
Diptera stand alone amongst the orders of Insects in the pecu-
liarity of possessing only two wings, the hinder wings being
represented by a small organ on each side of the thorax behind
and below the wing-root, known as the halter. These halteres
are invariably present in all the winged forms of the Order, and
generally present also in the very few wingless ones. In rare
cases the female only is wingless.
The mouth-parts exhibit a wide diversity in structure, but they
are nearly always in the shape of a proboscis, formed for sucking,
or, in some groups, for piercing the skin of animals or man for
the purpose of imbibing the blood.
The antenne also show extreme range in form, but are valuable
as one of the primary means of classification. The palpi have
from one to five joints, the usual number in the NuMATocERA
being four ; in the Bracnycura and the Muscrp#, two, of which
the first is small and often more or less rudimentary.
The wings exhibit a multiplicity of schemes of venation, all
referable ultimately to a common general plan, and this latter
character, the venation, perhaps affords the soundest basis for
classifying the families, at any rate, so far as the perfect insects
only are concerned.
The larva in the Diptera is apodal, moving by means of small
external transverse ridges or stiff bristly hairs, and progressing
by a wriggling motion from side to side. In the vast majority
of the species, the habitat of the larve (popularly known as
“ orubs” or ‘maggots ”) is decomposing vegetable or animal matter,
principally the former (the bulk of the higher Muscrpm and a
large proportion of the AcaLyprrats Muscip#) ; a considerable
number of species are root- or leaf-miners (ANTHOMYINA,
TryperIn®)*; a further considerable number are aquatic
(Cunicip#, CHIRONOMIDH, many TIPULID#, STRATIOMYIDE and
ACALYPTRATA, some TABANIDA, and various genera in many other
families); and a few are parasitic on mammals or birds (CistRIDa,
Hirroroscrp#),t insects (CONoPIDS, etc.), spiders (CyRTID£), and
other creatures. Some live in the earth (TaBaNnip#, ASILID2,
Emp), a few are carnivorous (certain SyRPHID#); and one
family forms galls (Cucipomyip#) : in short, the larve of Diptera
as a whole exhibit the most varied methods of existence.
* Some Indian Tryretin& live in rotten wood or in fruit.
+ Although in Hiprozoscrp# the larve develop in the body of the parent,
the life of the imago is passed upon the body of its host.

2 INTRODUCTION.
The pupa is fixed or free; in the great division of the
ORTHORRHAPHA it is mummy-like, that is to say, shewing more or
less in outline the parts of the future imago, the shape of the
head, antennze, wings, and legs often being conspicuous; in the
second great division, the Cycrorrnapna, it is long egg-shaped,
bearing no resemblance to the future insect, and exhibiting no
parts whatever of the body in outline.
In the perfect state (imago) Diptera are to be found practically
everywhere and in every conceivable situation, a few species
occurring even in very high latitudes and desert areas.
A general introduction to the whole order of the Diptera is not
contemplated in this volume, and the various parts of the insect
are sufficiently well known to the majority of entomologists not
to require more than a brief description. The following ex-
planatory paragraphs on the external anatomy of a fly are there-
fore curtailed as far as expedient. The genus T%ipula is selected
as an example owing to its being the chief genus of the TrruLipa,
the dominant family included in the present work.

A. Terminology.*
The Head.
The upper part of the head lying between the eyes is known
as the vertev, and an imaginary line dividing it from the back
of the head, or occiput, is called the vertical margin. Sometimes
a difference of colour clearly defines the limits of these areas, but
more frequently such is not the case.
The frons, or front, is the whole space between the eyes from
the vertical margin to an imaginary transverse line above the
base of the antenne. The vertex is really therefore simply the
upper part of the frons, but it is often occupied by a somewhat
conspicuous tubercle, or by a more or less triangular impressed
space with rounded corners, in which are situated the three small
simple eyes known as the ocelli, placed in a triangle, the apex
of the latter pointing downwards, that is towards the antenne.
These ocelli are in many families absent, in others reduced to
two in number, and they may, in a few groups, be placed more or
less in a straight line across the upper part of the frons.
Those Diptera in the males of which the eyes touch each other
in front for any considerable distance, are termed holoptic; those
in which the eyes in both sexes are separated by a broad frons,
are termed dichoptic. Although many cases occur in which it is
difficult to decide in which category to enrol them, the vast
majority of Diptera can be allotted at first sight to either the
holoptic or dichoptic class.
In holoptic Diptera, through the eyes not being contiguous
absolutely the whole distance from the vertex to the antenna,
there is always a small inverted triangle just above where the eyes
meet, its apex pointing downwards, and this is called the vertical
triangle. At the point where the eyes separate again, a little
above the antenne, is another more or less triangular space with
its apex pointing upwards, and this is called the frontal triangle.
Obviously, in flies with the eyes wide apart, both triangles are
merged in the frons and in such cases cannot be differentiated
from it.
Cyclorrhaphic Diptera technically possess what is known as
the frontal suture, and the presence or absence of this suture is
* This section defines the principal general terms in constant use; the more
specialized ones are explained at more suitable places throughout the text, but
all are, without exception, to be found in the Glossary.
+ The majority of the Bracuycera, except Asitinm and Doticuorrp®,
speaking of the larger groups only, are holoptic, as are also the Calyptrate
Muscip# as arule, and the Ruyeutp#, Breionip®, and some BLEPiwAROCERID®
in the Nemarocnra. The remainder of the Nemarocera, with the AsiLip*,
Doxicuorip” and Acalyptrate Muscip, are usually dichoptic, at least in the
more extensive groups.

4 INTRODUCTION.
theoretically the only decisive character by which to distinguish
members in the imago state, of the CycLorrHaPHa or ORTHO-
RRHAPHA respectively ; but as three of the principal families do
not possess the suture when they should theoretically do so, the
value of the character from a practical point of view is very
greatly diminished. This suture, when present (it is never found
in the OrTHORRHAPHA), is a more or less oval, or most frequently
crescent-shaped, narrow groove, sometimes reduced to an impressed
line, and is situated immediately above the base of the antenna,
and the small space it encloses is termed the frontal lunule.
Through this space is thrust out during the pupal stage, the
ptilinum, an inflatable organ by means of which the perfect insect
springs off the cap of the pupa-case to enable it to emerge.
Occasionally this ptilinum remains inflated in the perfect insect,
as I have seen several specimens of Syrphus with it still blown
out even in the dried insects.
In many Cyclorrhaphic Diptera, especially among the higher
Muscids, there is a well defined band, varying from a very narrow
space to one of considerable width, on the inner or frontal side of
the eyes, often slightly different in colour from the rest of the
frons, not infrequently appearing brilliantly shining white when
viewed from above or below. This is known as the frontal ocular
orbit, or inner orbit; other margins of the eyes are spoken of as
the facial (below the antennez) and posterior orbits respectively.
These orbits are rarely present in the NEMATOCERA.
Below the antennz, as far as the mouth, is the face, and
posterior to the face below the eyes are the cheeks or gene.
--'The epistome, or epistoma, is a slightly vague term, but strictly
speaking it means the mouth-opening, and an indefinite space
immediately contiguous thereto. It is probable that a good many
authors have used the term to include the whole of the lower
part of the head when not dealing with any particular part; in
fact, I have used the term myself in this general sense when a
very brief description sufficed for the whole of the underside of
the head.
Many groups of Diptera possess a system of bristles about the
head as well as on the thorax, but since this does not occur in the
Nematocera, the subject is not entered upon here.*
The Thorax.
The thorax in the Diptera is seldom divisible into the component
parts—prothorax, mesothorax, and metathorax—but forms a uni-
form oval, oblong, elongate, or sub-quadrate central piece in the
front of which the prothorax is sometimes discernible, though in the
NuMaToomrRA, especially in the TrpuLIDa, it is often obvious in the
form of a circular flattened disc, termed by Osten Sacken the collare.
The front part of the thorax when elongated to any appreciable
extent is termed the neck, but in some families the head is too

EXTHRNAL ANATOMY. 5
closely applied to the thorax for this to be visible. In the average
Dipteron, the head moves with great freedom upon the neck, and
is capable of being turned in all directions. The metathorax is
hardly distinguishable from the mesothorax, especially on the
upper side.
On the shoulders, that is, the anterior corners of the thorax, a
slight swelling is often present, known as the humerus, or humeral
callus or callosity. These humeral calli are frequently absent, and
when present are very often differently coloured from the rest of
the thorax. Other calli situated on various parts of the thorax
bear significant names. The pre-alar callus is a small swelling in
front of the wing-root, towards the side of the thoracic dorsum,
which latter is generally spoken of as the mesonotum. The post-
alar calli lie behind the wing; when they are on the hinder
corners of the dorsum they are termed posterior calli. Sometimes
I have used the term post-sutural calli in place of post-alar calli.
Across the centre of the mesonotum in many Diptera is seen a
more or less distinctly impressed line, often somewhat like a very
widely opened V, faintest in the middle, and ending on each side
a little in front of the base of the wings. This is the transverse
suture, and it has a high morphological value, being very con-
sistent when present. In the Nemarocera it is a strong character
of the TrpuLipm (with one or two comparatively unimportant
exceptions). Behind this suture (speaking now principally of
T1puLID#) and between the slight swellings of the post-alar calli
is a slight depression, which in the present work is referred to as
the post-sutural depression.
The presutural depression is a small depression at each end of
the transverse suture, usually triangular in shape.
The supra-alar groove is a groove on the mesothorax just above
the wing-root, and in many species bristles of taxonomic import-
ance are found along its inner margin.
The scutellum is a projecting posterior lobe of the mesonotum,
and a horny irregular ridge-like projection joining the scutellum
on each side to the mesonotum is termed the scutellar ridge. It
is sometimes, but not usually, conspicuous.
Behind and below the scutellum is the metanotum, a smooth
and more or less swollen part, attaining its maximum develop-
ment in the Trputma#, in which it is usually much more
conspicuous than the scutellum.
The halteres, which in Diptera replace the posterior wings, are
small delicate organs consisting of a narrow moderately long
stem, ending in an oval club, which occasionally is flattened or
spatulate.
The sides of the thorax in many Diptera are distinctly sub-
divided by impressed lines known as plewral sutures, whilst in
others such demarcations are not perceptible ; when present they
divide the sides into pleural spaces, which in some groups are
well defined, whilst in others they are very indefinite. Most
authors speak of them in general terms as “ the pleure.” These
6 INTRODUCTION.
pleural divisions do not afford so many taxonomic characters in
the Nematocrra as in some other groups, being always devoid of
bristles, and it is these latter which are strongly indicative of
affinities.

The three prinicipal sutures recognised generally are, (1) the
dorsopleural suture (or notoplewral) running from the shoulder to
the base of the wings and dividing the dorsum (or mesonotum)
from the pleure as a whole; (2) the sternopleural suture,
roughly speaking, parallel with the dorsopleural, placed about the
middle of the body or alittle below it, and dividing the mesopleura
from the sternopleura; and (3) the mesopleural suture, a more or
less vertical irregular line from the base of the wings downwards,
dividing the mesopleura from the pteropleura.
The pleure themselves are distributed as follows :—The pro-
pleura, or prothorax (generally termed the latter in the present
work), is on the immediate anterior part of the thorax. The
mesopleura lies behind it, in front of the wings, bounded above by
the dorsopleural suture and below by the sternopleural suture.
The metapleura lies immediately behind the wings, above and
rather behind the pteropleura, which lies directly below the wings,
extending downwards to between the two hinder pairs of legs.
The hypopleura is a small piece below the metapleura and imme-
diately over the hind coxe. The sternoplewra is usually the largest
of all and lies below the sternopleural suture and extends down-
wards, occupying all the space between the front and middle legs.
The mesopleural suture therefore has the mesopleura and sterno-
pleura in front of it and the pteropleura behind it. A small piece
behind the metapleura is known as the plumula; and a small
orifice on the prothorax just below the dorsum is the thoracic
stigma.
Since the NematoceraA are wholly eremochetous, that is to say,

devoid of strong bristles on the body (the Mvycrropninip®
possess conspicuous and characteristic bristles on the /egs), it
seems unnecessary to dilate here on the scheme of chetotaxy, or
the systematic study of these appendages ; but a brief outline of
the system is given in the Glossary under Chetotavy.
The Abdomen.
Few special terms are in use regarding the abdomen except that
the external male genital organs are spoken of collectively as the
hypopygium,* whilst the female organs are known as the ovzpositor.
The eight segments of the abdomen are numbered from the base
onwards, the usual terms used in the Tipunipm, where the
covering of this part of the body is represented by a distinct
dorsal and ventral plate, being tergum and sternum respectively.T
The Legs.
These also call for but little description, most of the terms being
in common use. The acetabulum is a minute joint attaching the
coxa to the body; the cowa is the short first obvious joint which is
united to the femur, the first long conspicuous part of the legs, by
another minute, ring-like piece, known as the trochanter. The tebia
succeeds the femur and is the second conspicuous division, followed
by the tarsus, or foot, which is invariably composed of five joints.
These joints are numbered from the basal one, which is known either
as the metatarsus, or the first tarsal joint. Care must be taken to
note that the next joint following the metatarsus is the second.
Attached to the extremity of the ultimate tarsal joint are the
ungues, or claws, two curved hooks, and below these are two pad-
like cushions or pulvilli.g These are often absent in the OrTHO-
RRHAPHA. Between the claws, and below them, attached, like the
pulvilli, to the last tarsal joint, is the empodiwm, which sometimes
takes the shape of another pad, in which case it is said to be
pulvilliform, and sometimes that of a thick bristle or spine. Osten
Sacken placed much reliance on it as a classificatory character
in Treuttp#, but I am inclined to doubt its value to such an
nay ee ne Se ee
* Bergroth has proposed propygiwm, but hypopygium is universally adopted
by dipterologists, whenever a special term is used.
+ Westhoff terms the upper and lower sides of the 8th segment the lamella
basalis supera and infera, respectively, and those of the 9th segment or the one
actually developed into the genital organs, the lamella terminalis supera and
infera, respectively, but I know of no one who has adopted these unwieldy
names,
t The exceptions are very few and only amongst abnormal forms.
§ Too much importance should not be given to minor differences, such as the
comparative size, toothed nature, and so on, of the ungues, presence or absence
of empodia, ete. When Theobald’s first volume on the Cunicrp& of the world
was published, great stress was laid on very microscopic differences in the shape
and size of the different pairs of claws, and in my Catalogue of Oriental
Cuuicip#& the great importance of these characters was questioned. In sub-
sequent volumes of Theobald’s work it was admitted that they did not possess
the value at first accorded to them.

extent. Often it is absent, and occasionally it is present when the
pulvilli themselves are wanting.
The anterior legs are the four front legs taken together, the
posterior legs the four hind legs similarly considered. When
spoken of singly they are called the fore (front or first) pair ;
middle (median or second) pair; and the hind (or third) pair.

The Wings.
The Veins—As a typical wing from which to illustrate the
venation,* having special reference to the NemMarocera, that of
Lamnophila has been chosen.t
The front margin of the wing is known as the costa, and is
* The term neuration was employed by many of the older authors instead of
venation, but the latter is at present in almost universal use.
+ It must be understood that a diagrammatic wing to expound the whole
theory of venation throughout the Diptera is an impossibility, and the wing of
Limnophila is selected because it possesses the greatest number of cells and
veins in the Nemarocera, The relative lengths and positions of these are given
in the main as for Limnophila, but it must be understood that these propor-
tions vary in different groups and to a still greater extent in different families.
The student should be able, after mastering the terminology of one family, to
identify the corresponding veins in others, and to recognise which are present
and which are absent or modified.
EXTERNAL ANATOMY. 9
carried right round the wing uninterruptedly, without any
distinct or sudden termination near or just beyond the tip, as in
some families of NEMATOCERA.
The auacliary vein is the first vein below the costa, and generally
ends, in the T1pULIDm, between the middle (or just before the
middle) and about three-fourths the length of the wing. It is
connected with the costa quite near its base by a short upright
cross-vein, the latter known as the humeral cross-vein. The
auxiliary vein is often known as the subcostal, which is perhaps a
better name, but since in studying T1ruLip# the works of Osten
Sacken must be consulted, his name for this vein is adopted in
preference.
The next vein is a much longer one, running parallel with the
auxiliary vein and ending some little distance beyond it; this is
the lst longitudinal vein. It either turns up rather suddenly at
the tip into the costa, as is generally the case in the LimNnosrina,
or turns distinctly down at the tip into the 2nd longitudinal
vein, as is usually the case in the Trpuninm®. In some few cases
it fades away at the tip without turning either up or down. The
auxiliary vein often lies so closely in front of the 1st longitudinal
vein as to be imperceptible unless carefully looked for. In some
few genera these two veins are actually united (Voworhina, Styrin-
gomyia), and in these cases the Ist longitudinal vein, as the
united veins are invariably called, generally approximates gradually
to the costa, finally becoming merged in it, and not turning dis-
tinetly up or down at the tip as in the typical forms. The
auxiliary vein and the Ist longitudinal are, in the T1puLipa,
nearly always connected by a short cross-vein known as the sub-
costal cross-vein, which is most frequently situated towards the end
of the auxiliary vein, but sometimes occurs a little before or after
the origin of the 2nd longitudinal vein. Considerable importance
attaches not only to the actual length of the auxiliary vein, but to
the relative position of the subcostal cross-vein, although exceptions
occur, even in otherwise closely allied genera (in the Er1oPTERINt,
for instance).
The 2nd longitudinal vein emerges from the first, usually some-
where near the middle of the latter, sometimes in a straight line
at a more or less acute angle, but more often in a gentle or
distinct curve. When the 2nd longitudinal vein is ‘ simple”
(that is to say, pot forked) there is only one submarginal cell ; *
when the 2nd vein is forked there are two, and this character is
of paramount importance, being the very first one employed in
separating the subfamilies; and on it depends the terminology
of many oi the cells.t The portion or section of the 2nd
* Vide p. 13 for description of ceils.
+ The principal exception in Oriental genera is Gonomyia, in which some
species have but one whilst others have two submarginal cells. This instability
is very exceptional as a generic character (Gonomvyia).
10 INTRODUCTION.
longitudinal vein * between its origin and the point of forking is
called the prefurca; the two branches, after forking, are the
“anterior and posterior,” the “upper and lower,” or the “ fore
(or front) and hind,” respectively.t
It may be noted here that Mr. Verrall uses the term prefurca
for the “common origin” of the 2nd and 3rd longitudinal veins,
that is to say it terminates at the origin of the 3rd vein, but it is
adopted in the present work in Osten Sacken’s sense, comprising
the whole of the 2nd vein as far as the fork. The section of the
prefurea between the origin of the 3rd vein and the fork of the
2nd is often referred to as the petiole of the 1st submarginal cell.
Naturally this only applies when the 2nd vein is forked, as
otherwise there is only one submarginal cell.
The marginal cross-vein is placed near the tip of the 1st longi-
tudinal vein, joining it to the 2nd vein and dividing the
marginal cell into two parts, often into about equal halves, these
being known as the inner and outer marginal cell respectively.
When the 2nd vein is forked this cross-vein may unite with the
upper branch or with the prefurca, and it has a tendency to
indistinctness in many species. It is present in the large majority
of genera in TrpuLIp®, but is absent in some (Atarba, Toxorhina,
Rhamphidia, ete.); it is indistinct in Limnophila, present in
Ptychoptera and the Trputin x, whilst in the CyLrypROroMINT it is
replaced by a small and often indistinct cross-vein between the
Ist longitudinal vein and the costa. The value of its presence or
absence has been oyer-estimated by one or two authors, although
it can usually be accepted as a good character.
The 3rd longitudinal vein emerges trom the prifurca in nearly
all the T1puLipm®,t and the preefurca itself is often bent downwards
at a more or less distinct angle at the point of contact. The 3rd
vein is simple in all the Oriental genera, except in the subfamily
PrYCHOPTERIN®, in which its forked nature constitutes one of
the principal characteristics of the group. It is nearly always
present, any genus without it being most abnormal. In Towo-
rhina it is altogether absent, the anterior cross-vein connecting
the 2nd and 4th longitudinal veins; in Mongomea (according to
my interpretation of the venation) it is reduced to a short longi-
tudinal connecting vein between the middle of the praefurca and
the 4th longitudinal, thus not even approaching the margin of
* Tt will be understood that the abbreviation “1st vein,” “ 2nd vein,” ‘‘ 3rd
longitudinal,” and so on, in all instances means the Ist longitudinal vein, 2nd
longitudinal vein, 3rd longitudinal vein, ete.
t+ When once the principle is thoroughly understood that it is the second
longitudinal vein which forks in Trruni™m (and hardly ever the third), it is
not of great consequence what may be the exact terms used; nor is there any
unanimity in the matter. In company with other authors I use all the
terms quoted indiscriminately.
{ The principal exception is Amalopis, in which it emerges either from the
posterior branch of the 2nd vein or from the prifurca, according to the
species,

the wing.* In Ptychoptera, the principal genus of the subfamily
PrycHoPTERIN®, the 3rd vein issues from the prefurca at a point
where that vein makes such a sharp angle that the general
appearance is that of two long veins crossing one another nearly
at right angles,t the first being composed of the basal section
of the 2nd vein and the 3rd vein; the 2nd vein being com-
posed of the anterior cross-vein and the remaining section of the
preefurca.
The next vein is probably the most important of all in the
wing: this is a short cross-vein which almost invariably through-
out the Order connects the 3rd and 4th veins when both are
present ; and this vein, the anterior cross-vein,t is, in conjunction
with the discal cell, technically, a key to the venation in the
whole order of Diptera.§ It divides the wing longitudinally into
two nearly equal halves, and no vein found in front of it in one
group is ever found behind it in another. When the discal cell is
present the anterior cross-vein is placed immediately above it {in
TrpuLip®), usually, at or near the base of the cell, rarely beyond
it (Conosia). When the discal cell is absent this cross-vein unites
the 3rd longitudinal vein to that part of the 4th vein which would
have formed the anterior side of the cell, had it been present. In
the Numatocera it can nearly always be employed as a central
vein around which to recognise the adjacent veins; and a little
practice and comparative study of the wings of other families
will enable the student to determine it with tolerable accuracy.
It is usually more or less upright, generally short, sometimes very
short, more rarely moderately long; being wholly absent in only
a very limited number of quite abnormal genera of TrPULID.||
Having recognised the anterior cross-vein, joining the 5rd and
4th longitudinal veins, it is easy to find the 2nd longitudinal! vein
and to ascertain, according as that vein be simple or forked, whether
there are one or two submarginal cells. The cell on the inner
side of the anterior cross-vein is the Ist basal cell, the cell on its
outer side is the lst posterior cell. This rule is practically
inviolate, not only in the TreuLip#, but in all families of Diptera
with a tolerably complete venation.
The 4th longitudinal vein begins at the base of the wing, and
invariably encloses, or rather constructs, the discal cell (when
* This is the only instance I know of showing this abnormality, and it is
just possible that the vein might be more correctly regarded as the anterior
cross-vein, This, however, is doubtful—vide discussion under Mongonva.

{ Also known as the “small cross-vein,” and the ‘internal transverse vein.”
§ This must not be taken too literally, as exceptions embracing whole families
occur, such as the Cecipomyip®, SImvnimp#, and outside of the Nemarocera, the
Puorip4, ete., but all thése exceptions are instances of incomplete or aberrant
venation.

12 INTRODUCTION.
this is present) by being, in these cases, always forked, the
absence of the discal cell being only caused through the absence
of a short cross-vein between the two main branches of the 4th
vein, and this cross-vein is usually called the discal cross-vein, on
account of its dominating the discal cell. It will be seen that the
4th longitudinal vein forks at the discal cell,* its upper or anterior
branch forming the basal and anterior sides of this cell; the lower
or posterior branch forming the posterior and outer sides of the cell.
Apparently, the outer or distal side of the discal cell is formed
in most genera of TrpuLip% by two short veins, both nearly
straight themselves, yet not often in a straight line with one
another. The upper one of these short veins is my discal cross-
vein, the lower one is considered part of the lower branch of the
4th vein, the straight continuation of the basal part of the 4th
vein being regarded as a branch vein known as Loew’s posterior
intercalary vein. The upper branch of the 4th vein, after quitting
the discal cell, forks again, the upper prong being considered as
the continuation of the vein itself, the lower prong the branch
vein, and this latter is known as Loew’s anterior intercalary vein.T
When the anterior or upper branch of the 4th vein is forked, the
section between the discal cell and the fork is known as the
petiole of the 2nd posterior cell. -In the same manner, in a case
where there is no discal cell and the posterior branch of the 4th
vein is forked, it would be correct to speak of the corresponding
section of that branch as the “petiole” of that posterior cell
which was contained by the fork.
Somewhere beyond the middle of the 4th longitudinal vein is a
longer cross-vein, generally more or less obliquely placed. This is
the postericr cross-vein, which in T1euLIDm invariably connects
the 4th and 5th veins, and is practically always straight itself,
* Slightly but distinctly before it in Megistocera, the ouly exception known
to me.
} It seems to me that although the lower prong of the upper branch of the
4th vein is really the additional veinlet due to the forking, a mistake has been
made by even Loew, one of the soundest of dipterologists, in regarding the
upper prong of the lower branch of the 4th vein as the true continuation of
that branch, since, when this lower branch is not forked it never takes the
course containing two sharp angles but continues in a more or less straight
line to the wing-margin. This compels me to believe that the /ower prong is
the true continuation of the lower branch of the 4th yein, and that the upper
prong is the additional veinlet due to the forking and that this upper prong
should have been named the posterior intercalary vein by Loew. I have not
seen this view suggested anywhere, but unless it be admitted, the anomaly
would be presented of the lower branch, when forked, taking two abrupt angles,
but when simple, proceeding in a straight line to the wing-margin, a curious
and quite illogical theory. This view applies to the Limyosim only, as in
the Tirvtinx, in which the lower branch is always forked, the lower prong
appeals irresistibly to me as the additional veinlet, and the upper one (forming
part of the discal cell and being much less angulated) as the true continuation
of the lower branch. There seems nothing illogical in the assumption that an
additional veinlet may occur on either side of a parent yein as a subfamily
character.
EXTERNAL ANATOMY, 1133
e
though placed at various angles to the two veins it connects.
Occasionally (in Mongoma, for instance) the 5th vein bends down
at the tip, meeting the 6th vein and thus closing the anai cell,
instead of running to the margin of the wing as in most genera.
The 5th longitudinal vein, with the 4th, the 6th, and 7th all
spring from the base of the wing. The 6th longitudinal vein lies
posterior to the 5th and is normally straight or only gently
curved;* the 7th longitudinal, being the last vein, usually parallel,
or approximately so, to the length of the wing.
In TrrevLip#, the 5th, 6th, and 7th veins are never forked.
The 7th vein varies in length and direction; in the Prycuoprn-
RINZ it is comparatively short, taking a distinct downward curve
at the tip to meet the wing-margin. In TZ'richocera the same
thing occurs, only the vein is much shorter still, so short as to
be easily overlooked altogether. In other genera, Mongoma for
instance, the 7th vein, though much shortened, is only gently
curved.
The term central cross-veins was sometimes used by Osten
Sacken to designate the veins between the end of the prefurca
(transversely across the wing’s length) and the posterior cross-
vein; in this case the short basal section of the 3rd vein, the basal
part of the fork of the 4th and both sides of the diseal cell would
be included in addition to the two cross-veins proper.
Not infrequently a genus or species is distinguished by the
presence of an extra vein which is constant in its occurrence. Such
veins are called supernumerary. When they occur abnormally in
individual specimens (often in one wing only) they are called
adventitious, and such occurrences are quite frequent, especially
in the Ertoprurint, in which their unexpected presence causes
much difficulty to the beginner.
The Cells.—The recognition of the cells, once the terminology
of the veins is mastered, is comparatively easy.
The first, immediately below the costa, and bounded pos-
-teriorly by the auxiliary vein, is the costal cell; that between the
auxiliary vein and the Ist longitudinal vein (often difficult to
perceive on account of these two veins lying so close to one
another) is the subcostal cell. In cases where the auxiliary vein
and the Ist longitudinal vein are united (ovorhina, Styringomyia)
the subcostal cell is of course absent.
The 2nd longitudinal vein always has in front of it the marginal
cell, When the 2nd vein is simple the ce!l immediately behind it
is the submarginal, but when the 2nd vein is forked there are
two such cells, in which case they are called the 1st and 2nd
* Absent altogether in Prycnoprmrin™.
+ This is rather a vague definition, but so many species have clear wings
except for slight infuscations on all the veins or portions of veins that lie
transverse to the wing’s length, that most authors have adopted it for descrip-
tions of certain species at some time or other, myself included. The term
should in any case be used with caution.
14 INTRODUCTION.
submarginal cells respectively.* Care must be taken in those
genera (Gonomyia, Mongoma, etc.) in which the fork of the 2nd
longitudinal vein is short and nearly perpendicular, giving it the
appearance of a cross-vein, for which it might easily be mistaken.
When the marginal cell is divided by the marginal cross-vein,
as is the case with most genera of TrpuLID®, the divisions of the
cell are known as the inner and outer marginal cells respectively,
but when speaking of the united cells the term ‘“ marginal cell ”
is correct.
It will thus be seen that the 3rd vein has in front of it the
submarginal cell, if the 2nd longitudinal vein be simple, and the
2nd submarginal cell, if the 2nd vein be forked.
Immediately below the 3rd vein is the anterior cross-vein, the
key to the whole venation. This vein always joins the 3rd and
4th longitudinal veins, exceptions being very rare (Amalopis),
and it always meets the 4th vein at the discal cell (usually at
the anterior upper corner of the latter), when this cell is present.
However, whether the discal cell be present or not, the anterior
cross-vein meets the 4th vein exactly or very nearly at the same
place. Thus the discal cell in the vast majority of Treunip# has
the 1st posterior cell in front of it, and (except in Trputinz) the
ultimate posterior cell (4th or 5th, etc., as may be) behind it.t
The anterior cross-vein always bounds on its inner side the
1st basal cell, below (or posterior to) which latter is the 2nd basal
cell, of varying relative length but always conspicuously longer in
TrpuLip# than in most families of Diptera.
Behind, or posterior to, the 1st posterior cell the other posterior
cells run on in numerical order, four being the usual number in
this family, less frequently five (Limnophila, Oladura, some
Eriocera) ; occasionally only three (Bittacomorpha, a non-Oriental
genus), the last posterior cell being that one of which the posterior
cross-vein forms the base.
Posterior to the 5th longitudinal vein is the anal cell, open in
* In the case of Ptychoptera, where the unusual eyent of the 3rd longi-
tudinal vein forking instead of the 2nd is found, the same rule as to the
nomenclature of the cells holds good; thus the Ist submarginal cell is bounded
by the 2nd vein and the upper branch of the 5rd vein, whilst the 2nd sub-
marginal cell is bounded by both the branches of the 3rd vein. One or two
authors have contended that it would be more correct, when the 2nd vein is
forked and the 3rd vein simple, to regard the cells as two marginal and one
submarginal ; and when the 2nd vem is simple and the 3rd forked, as one
marginal and two submarginal ; that is to say, all cells bounded posteriorly
by the 2nd vein would be called marginal cells, and those bounded posteriorly by
the 3rd vein, submarginal cells, in each case irrespective of their number. In
the conceivable case of both 2nd and 3rd veins being forked, there would be
two marginal and two submarginal cells.
+ The: only exception in T1ruLipa amongst Oriental genera is Conosia, Wied.,
in which the anterior cross-vein is placed very distinctly beyond the discal cell.
{ Of course, when the posterior cross-vein is placed so far distally as to be
beyond the limits of the discal cell, the latter is bounded posteriorly by the
2nd basal cell. It invariably has the Ist basal cell on its inner side. In
the Tiputina the penultimate, not the ultimate, posterior cell bounds the
discal cell posteriorly, on account of the lower branch of the 4th longitudinal
vein forking just at the lower basal corner of the discal cell.

the great majority of genera in TreuLip%, but occasionally closed
(Mongoma) by the turning down of the 5th vein at its tip,
meeting the 6th vein before the border of the wing. When open,
therefore, it runs the whole length of the wing from the base to
the wing-margin. Posterior to “the 6th vein is the axillary cell,
In Treuntm#, in which the 7th vein is nearly always complete,
that is to say, attains the margin of the wing, there is of course
yet another cell—the last—in the hind angle of the wing. In
those families of Diptera which have the 7th vein incomplete, all
the space between the 6th vein and the hinder angle of the wing
is considered the axillary cell (called by some of the older authors
the ‘ spurious ” cell, presumably on account of its ill-defined
nature). Some authors speak of a lst and 2nd anal cell, plus an
axillary cell. Where there has been occasion to mention this
ultimate cell specially as such, it is herein called the 2nd avillar y
cell, thus retaining only one anal cell in the wing.*
Wing pubescence.—A note may be made here regarding the
terms “‘ wings bare” or wings pubescent” in this family. It is
probable that under very high microscopic power every wing will
be seen to possess extremely minute stiff hairs, but when such
are wholly invisible to the naked eye or to an ordinary entomo-
logical hand-lens, the wing is considered bare, or, as some authors
have termed it, glabrous; and generally it is more or less
iridescent. These microscopic sete are therefore never regarded
as pubescence. When the naked eye or a hand-lens reveals
distinct hairs on the veins or on the surface of the wing itself,
the wing is considered pubescent. Practically all the veins bear
microscopic short stiff hairs, but if these are not clearly seen
without a microscope, the veins are not termed pubescent or
bristly,

axillary lobe. Behind this is an indentation of the wing-margin
called the awillary incision, and beyond this again (working
towards the base of the wing), is a small, more or less well
developed continuation of the wing--the alula. In some wings,
such as those of cuneiform shape, the axillary lobe is, perforce,
absent, and the alula is reduced toa minimum. Behind the alula
are two more or less rounded, scale-like organs, generally of a
dirty white colour, and frequently with a fringe of hairs on the
edges; these are the squame, and they have given rise to con-
siderable dispute as to their correct names. When the wings are
folded, the upper one, which is nearly always the smaller of the
two, partly covers the lower one, and when the wings are out-
stretched the upper one moves forward, being actually the
extreme base of the wing, and the lower one, then fully disclosed,
is seen to be definitely fixed to the thorax.
The term tegule appears to date from Loew, in 1844,* when
he distinctly differentiated it from the alula (the final basal lobe
of the wing), and it is applied to the squama which is fixed to the
thorax. Osten Sacken invented antitegula for the anterior scale,
to which at times it was necessary to refer specially, and he gives
a clear resumé of the various terms used for these parts in a short
paper.t He also suggests as alternative names to antitegula and
tegula, antisquama and sgywama, when speaking of each separately,
or simply squame (in the plural), if both pairs together be referred
to. Inthe present work the two pairs, anterior and posterior,
taken together are sometimes described as the sqgwame and some-
times as the tegule.t Since, in the Nsematocera the thoracic
squama is very rudimentary, there have been few occasions to
refer specially to either the anterior or posterior pair.
Jonfusion has frequently arisen owing to many authors. calling
these structures the alule; and a recent writer, Comstock, still
adheres to this view, contending that the term tegula should not
be employed, having been preoccupied for the cup-like scale above
the root of the wings in some Hymenoptera. A great number of
terms have been applied to both the alule and the squame, espe-
cially the latter, but no advantage would ensue by discussing them
here.§ Verrall uses the names alar and thoracic squame, and
perhaps these are the most suitable of all.
As for the halteres or aborted hind wings, they are in some way
connected with the power of flight, since if they are removed, a
Dipteron flies erratically. They are short cylindrical stems,
bearing an oval or flattened knob or club at the tip, and are placed
behind and a little below the roots of the wings. The insect can
vibrate them with great rapidity in the same manner as a wing.

The Head.
The eyes.—With the exception of some of the EprososcrpEa
(PurrparA), the large compound eyes so strikingly prominent in
most species of Diptera, are invariably present. In the majority of
the NumMaTocera the eyes are separated by a frons, or front, of equal
width in the two sexes, but in most of the families of the Bracny-
crra (except the Astrinm and DoricHorip#), and in the great
majority of the higher Calyptrate Muscipm the eyes in the male
touch each other in front for a considerable distance. Exceptions
occur in some BLEPHAROCERID®, in which the head is holoptic
in one or both sexes, or dichoptic in both; also in the Cyrripa,
in which the eyes are contiguous in both sexes both above and
below. Asarule the eyes are always well separated on the under-
side of the head, but in many TrpuLip% they are there contiguous
or subcontiguous. In most families they are oval or semicircular ;
in some, enormously enlarged, occupying practically all the head
(Cyrtip», PreuncuLip®); in others, kidney-shaped (PsycHo-
pIDZ and many groups of MycrropHitip®). They may be
thickly or lightly pubescent, or bare, these features being often
not contingent on sex. Ina few families they possess coloured
bands in life (TABANID®, some AsILtp#), which fade after death,
but which may generally be caused to reappear by an application
of damp sand. In the genus Bibio the male eye is curiously
divided into two parts, and in most BLepHAaRocuRIDs# the eye, at
least in the male, is sharply divided into an upper and lower
part, the facets in one being very large, and in the other much
smaller, and the two parts being separated by a narrow unfacetted
band. In one small family of Acalyptrate Muscrp#, the Diop-
stnm, the head is produced on each side into long eye-stalks, at
the tips of which are placed the eyes. In some wingless PHoRIDz
the eyes are somewhat aborted.
The ocelli or simple eyes have been sufficiently described under
the heading “ Terminology.”
The mouth-parts.—“ No point of insect morphology has given
rise to more differences of opinion than the mouth of Diptera.”
(Dr. Sharp, 1899.) This being supported by the existence of so
many views as to the homologies of the dipterous mouth-parts,
the present references may be judiciously curtailed.
Of the various authors perused, I venture to select Williston’s
definition of these parts as being the most concise and recent
(1908). This author is therefore quoted verbatim :—
«The more commonly accepted homologies of the mouth-parts
are as follows: labium, maxille, maxillary palpi, mandibles,

hypopharynx, and labrum or labrum-epipharynx. The labial
palpi are thought to be wholly wanting or represented by the
labella.* The labium is always present, more or less fleshy and
provided with muscles. It is grooved or channeled on the upper
side to receive the other parts, with the exception of the maxillary
palpi, which are free. This sheath is often nearly complete, the
thin margins touching each other above. At its tip are the pair
of joints of variable size called the lips or labella. The maxille
and mandibles are sometimes absent, the mandibles most fre-
quently ; when present they are always slender and firm. The
hypopharynx is unpaired and slender, grooved on the upperside
and sometimes converted into a nearly complete tube. The
labrum, also unpaired, is usually elongate and grooved on the
underside, forming by apposition with the hypopharynx a com-
plete tube. The mandibles are frequently absent; in fact, [ do
not know of their occurrence in any flies with a simple third
antennal joint, and they may be absent in the male when present
in the female, as in the Tasanipm. They are always piercing-
organs, thin, firm, chitinous, and usually slender. The two
maxille, likewise piercing-organs, find their highest development
in such predaceous flies as the Asttipm. Like the mandibles they
are chitinous and slender. In some they are more or less flat-
tened, and may have curiously shaped projections at the tip;
usually they are bristle-lke. They he with the maxille within
the sheath of the labium, at either side of the labrum and hypo-
pharynx. In some cases the labrum is short, and serves only as
a cover for the proximal part of the hypopharynx, but usually it
is as long as, or longer than, the hypopharynx, and has a simple
groove on the underside. The hypopharynx is always present
in flies in which the mouth-parts are functional. It is, more
often, a slender firm organ, grooved upon the upperside, which
by apposition with the labrum forms a distinct tube. In some,
however, it may form an almost complete tube in itself.” ¢
The mouth in the Cunicip® may be described as consisting of
eight pieces of approximately equal length, the labium being
slightly longer than the others.t The labrum, or upper lip, is
uppermost, and closely united to it on the underside is an equally
long but very slender piece known as the epipharynx.f Two
slender lancet-like pieces come next: these are the mandibles,
and below these, two ‘‘ delicate needle-like organs, barbed at the
summit, the maxille.” There is alsoa “thin tubular thread,” the
so-called hypopharynx, this being connected with a poison gland
at its base. Below these is the stoutest piece of all, the labium or
lower lip, grooved on its upperside to admit of the reception of all
* This has been recently contested by Wesché.
+ This description is after Theobald (Monog. Culic. i, p. 3).

the labrum, but there are occasions when, exact reference to it being required,
a special term is necessary.

the other pieces except the labrum, which covers them like a
sheath from above. At the tip of the labium are two small oval
lamellz in the form of two spatulate jointed valves, and these
represent the labial palpi.
“During the act of piercing the skin, all the mouth-parts but
the lower lip (labium) are inserted ; the labium bends and guides
the other mouth-parts into the skin, The blood is drawn up the
upper lip, the tube being formed by the upper lip, and closed
below by the hypopharynx.”
Meinert wrote, in 1881, a copious anatomical essay on the
mouth-parts of the Diptera, presumably in Danish,* but his views
on many points are very original and not corroborated by the
examinations of other writers. He employs also a terminology
entirely his own.
The palpi.—For purposes of classification the most important
organs appertaining to the mouth? are the maxillary palpi, usually
spoken of simply as the palpi, as the labial palpi are considered to
be represented by the labella; some authors do not agree with this
view and think that the labial palpi are entirely absent in this
order: Wesché, in fact, has in recent times contested that either
maxillary or labial palpi may be present and functional, but no
cases are known of both pairs being functionally present.
The palpi in the vast majority of Diptera are either long and
composed of four joints, as is the case with the great bulk of the
NEMATOCERA, or quite short and composed of two joints, the first
being very small, as is the case in the bulk of the remaining
families. Occasionally a 5th joint is evidently present, though
its existence has been generally denied till quite recently ; in
these cases the conical protuberance of the proboscis, upon which
the palpi are in many instances inserted, is sufficiently differ-
entiated to form a distinct basal joint, but such instances are not
common. In two or three Oriental species of Phlebotomus this
basal joint is present. It seems hardly necessary to note that
the joints are counted from the base outwards, so that in a
2-, 4-, or 5-jointed palpus the last or terminal joint is the 2nd,
4th, or 5th respectively. In size, shape, and relative length of
the joints they exhibit great diversity, a considerable amount of
variation being found in the same genus, frequently a single joint
being enormously enlarged, or peculiarly formed.
Generally situated at or very near the base of the proboscis,
the palpi are in rare instances placed at its middle (Geranomyia),
or tip (Hlephantomyia) ; in these cases the proboscis is very con-
spicuously elongated. Williston says “the tendency in Diptera

is towards their entire loss, and in the more highly specialized
families there is never more than one joint.”
At the tip of the proboscis, or very near it, isa pair of larger
or smaller organs, generally distinctly visible, and more or less
oval in shape, known as the labella or lips. Their function varies
considerably, in some groups representing merely an apparatus
for holding, in others they are evidently sense-organs, being ‘ pro-
vided with hairs inserted in small semi-translucent: spots on the
outer sides and margins.” This is the case in most flower-
haunting flies, SyrpHip# for example. In the majority of Diptera
the labella are of fair or considerable size, and are provided with
radiating ridges on the inner opposable sides. These pseudotrachee,
as they are called, “serve as a means of attrition, by which the
insect rubs off particles of food from firm substances.” In at
least one family, the As1u1p®, they are rigid and horny. ‘‘ Some-
times the labella are long and slender, and are folded back under —
the labium when at rest.”
The mouth-parts in some Diptera are quite rudimentary, attain-
ing their most abortive state in the CEsrrip#, in which they are
almost absent.
The antenne.—These organs exhibit a wider range of variability
than any other in the Diptera, and to the beginner offer many
puzzles, although a moderate amount of study will enable one
to discriminate between the nematocerous, brachycerous, and
muscid types, of which the latter is somewhat quickly recognised,
although sume Syrphid antenne may easily be confused with it
at first sight.
As a means of classification the antenne have always been
regarded as furnishing one of the most fundamental characters.
It is significant that so long ago as 1802, when Latreille made the
first real attempt at classification by dividing the Diptera according
to the palpal and antennal characters, the long filiform nature of
the many-jointed antennez, combined with the elongate four- or
five-jointed palpi, was seen to be typical of the Nemarocnra (this
term being introduced by Latreille in 1817); whilst the short
three-jointed antenne, coupled with the one- or two-jointed short
palpi, of the rest of the Diptera were acknowledged as the charac-
teristics of the Bracuycmra, the latter term having been pro-
posed by Macquart in 1825. The valuable systematic characters
contained in the venation did not occur to dipterologists until
years afterwards.
In the Nematocera the antenne are always more or less elon-
gate,* often conspicuously so, composed normally of eight to
sixteen distinct joints; in a few cases, as in some males of species
of Eriocera in Treunip®, of six joints only; and in some other
instances, of as many as twenty-eight: in fact some authors have
* Wi ; :

EXTERNAL ANATOMY, A
claimed thirty-nine in a particular genus of Cuctpomy1pm (Cero-
zodia), hut this has been disputed on the grounds that some of
the joints are merely annular impressions. Lhachicerus (Luprip®)
has twenty-eight joints, and some genera of CacipoMy1D# possess
this number also.
The antenne in the Bracuycura consist technically of only
three joints, but in some genera (Hewatoma in Tapanip”, Xylo-
phagus and Ihachicerus in Luprip®) the 3rd joint is either dis-
tinctly or apparently divided into several joints, so that at first
sight it is not easy for a beginner to distinguish the location of a
species by the antenne alone. But in all such cases the very
short palpi and the totally different scheme of venation afford a
certain clue to their identity.
In the Nemarocura the two basal joints are almost invariably
differentiated from the rest, and are known as the scape or scapus,
the remaining joints being called the flagellum. The scape nearly
always bears a few stiff bristles, either irregularly placed, or
arranged in one or two more or less distinct rows near the apical
margins ; it is sometimes bare or practically so, but never verti-
cillate. The flagelluu in most of the Trputtp# and in some
other groups, bears a whorl of fine hairs symmetrically arranged
(in the TIPULIDm a very common number is four, two above and
two below, the upper ones often the longer) around each joint,
and the autenne are then spoken of as verticillate. This is the
normal form of antenna in the Trputip®. A few genera in that
family have pectinate antenne in the male, that of the female
being verticillate or much less conspicuously pectinate. The
CHIRONOMID# and CuLic1p# normally possess excessively plumose
antenne in the males, those of the females being generally verti-
cillate, whilst CectpoMy1p# generally possess verticillate antenne
in both sexes.
In the CycborRHAPHA only three joints are present, of which
the first is always short, often extremely so, the third frequently
being annulated, or possessed of a number of finely impressed
lines giving the appearance of a number of joints closely annealed.
It is curious that in these latter cases the 3rd joint never possesses
more than seven such annular impressions, thus suggesting eight
annealed joints, because the nematocerous antenne most likely to
be confused with such a form are those like Bibio, Plecia, ete., in
which the flagellum generally consists of eight subequal homologous
joints (though perfectly distinct from one another), whilst the
two basal or scapal joints have some considerable resemblance
to the first two joints of the antenna in Xylophagus. It is this
latter form, which is by no means infrequent, that may be mis-
taken by the beginner for an eight-jointed nematocerous antenna.
However, in all such doubtful cases the structure of the palpi
and the distinctly different venation immediately decide the
question of affinity.
With the Cyclorrhaphic antenna we have little to do in this
volume, but it may be stated that although it consists of three
22 INTRODUCTION.
joints only, the terminal joint takes the most varied and at times
extraordinary shapes, and may be elongate and porrect as in Ceria
(Syrpuip#), elongate and pendant as in the higher Muscrp»,
short and rounded as in most of the ANTHOMYID® and AcALYP-
TRATA. It may be furnished with an arista, along, gently curved,
bristle-like hair, which may be plumose, subplumose, pubescent,
or bare, or even extraordinarily pectinate as in one or two abnor-
mal genera of Tachinids; the arista itself may be dorsal, sub-
apical, or apical, or may be replaced by a more solid style-like
appendage.
The Thorax.
Little can be added to the notes given under “ Terminology.”
In most Diptera the mesothorax, usually known as the mesonotum
when only its upper part is referred to, occupies the greater
portion of that part of the body; both the prothorax (except in
some T1PULID#) and metathorax being very much aborted.
The thorax is normally oval or subquadrate; in many genera
exceedingly elongated (Calobata, Micropeza); in others highly
arched (Simulium, Platypeza, Hybos, Cyrvip®, etc.). In rare
instances the sides of the thorax are furnished with a strong
spine (Zphippium). The sides of the thorax or the pleure have
deen described above (p. 6).
The scutellum is variable in relative size, but is most frequently
semicircular or subtriangular. It reaches its most extraordinary
development in Celyphus, in which it forms an enormous spherical
cover for the whole of the abdomen, and as the insects are
generally smooth and shining, and of a metallic blue, green,
or yellowish colour, they are easily mistaken by the beginner for
beetles. The scutellum may be distinctly spined on the posterior
margin (as in many STRATIOMYID®), serrate, smooth, furnished
with bristles or pubescence, or quite bare.
The metanotum is in most cases hidden by the scutellum above,
except in some families of Nemarocrra in which it is often the
more conspicuous of the two. The vestiture of the thorax is as
variable as that of the abdomen.
The Abdomen.
The abdomen in the Diptera varies in the number of segments
from four (some ANTHOMYID# and ACALYPTRATA) to as many as
nine (in some MycrropHinip®); the normal number in the
NEMATOCERA being eight. The basal segment is often much short-
ened and almost invisible from above, the first two being some-
times more or less fused together. They are numbered from the
base, on the upper side, the genital organs not being counted as
a: separate segment.
The variations in shape of the abdomen are very great. It is
very elongate, narrowed, and cylindrical in TreuLip#, Currono-
MID®, and CuLicip#®; stout and shorter in some of the other
uematocerous families; very short and exceedingly broad and
EXTERNAL ANATOMY, 23
convex in many genera of Srratiomyip®; globular and almost
transparent in CyRTID#; oval or conical, as in most SyRPHID»,
and other families of Bracnycrra, and most of the higher
Muscip#; elongate and cylindrical in Asttipm, Doticnorip»;
subtriangular in many ANTHOMYID# and ACALYPTRATA,
In vestiture it varies also; thick long spines are present
in many genera of TaCcHININ®; in others, bristles, ordinary
pubescence, a pollen-like dust, or scales may form the covering.
The male genitalia in the Diptera exhibit the most diverse
modifications, and in many groups afford reliable specific characters.
Their taxonomic importance, however, must not be overrated,
and it must be recognised that they exhibit great variability, even
in the same genus. They reach probably their greatest develop-
ment in the Donicnopipm®, but are quite conspicuous in many
Tipunip#, MycnroruiLip®, ASILID®, and some smaller groups.
The female genitalia are much more uniform than those of the
male, consisting in the principal families of the Nemavrocera of a
pair of oval terminal lamelle often withdrawn into the body-cavity,
and in the Treunip® of a pair of exterior pointed valves;
whilst in nearly all of the Bracuycera and the Muscipa no
organs are visible exteriorly.
The Legs.
These organs vary throughout the order to an extraordinary
degree, from the exceptionally long and delicate legs found in
Dolichopeza, Cylindrotoma, and other ‘Tipunip®, to the short
incrassated ones in some of the EpHyprin™® and other groups
of Acalyptrate Muscrp®. They may be conspicuously dentate,
strongly spinose, bristly or practically devoid of hairs, densely
pubescent, or ciliate. Frequently the femur, tibia, or tarsus, or
one or more joints of the latter may be incrassate, or occasionally
fantastically formed, such modifications being at most generic,
often not of even that taxonomic value.
The Wings.
So far as the perfect insect is concerned, the venation of the
wings is, for purposes of classification, the soundest and most
reliabie structural character in Diptera. The exceptions, though
admittedly numerous, are of such a nature that although doubt
as to their exact systematie position may at first arise, they can
never be actually identified with a wrong family. Many families
or groups of families in the Diptera possess strikingly peculiar
types of venation of their own. Outside of the NpMaTocERa, one
soon learns to recognise, for example, the wing of a Stratiomyid
from the faintness of the veins near the posterior margin of the
wing and the equally unusual “ crowding-up” of the veins near
the anterior margin; and a Dolichopid may be known by the
peculiar “kink”, that is present in so many of the genera in that
family, placed about the middle of the 3rd and 4th longitudinal
veins ; while the SyrpHip® may be distinguished by the upturned
24 INTRODUCTION.
ends of the 4th and 5th veins, approaching the Muscid type, yet
quite distinct from the true Muscid form as developed in Musca
itself and its allies.
The Conopipm, Preuncunipz, PLaryprzip#, (Esrrip®, and
PxHoRID® have each one a striking and typical venation of its
own. Even in the vast mass of the Muscrpa, sensu lato, three
tolerably distinct types are present that contain the great majority
of the species ; these may be termed the Tachinid, the Muscid,
and the Anthomyid respectively. The Acatyprrata, although
nominally of the same general plan as the latter type in venation,
areas arule easily distinguished by the small, equal-sized, or absent
wing-seales or tegule, which in the ANTHOMYID are conspicuous
and of unequal size.
Among the other families of Bracuycera the student may at
first, from the wing alone, find it difficult to distinguish between,
say, the TaBpanip«#, Leprip”®, and THEREVID#; the various forms
of BomByLiip# and Asirip#, with the allied smaller groups ; and
the somewhat erratic types met with in the Empipm; but this
discounts but little the pronouncedly characteristic forms of the
other families, and a wider experience will enable him to determine
between these more allied types of venation.
Reverting to the Nemavrocorra, the CecipoMYIp x, CHIRONOMID2,
SIMULIID®, BLEPHAROCERID#, Dixtp#, and TrpeuLip# at least
have quite characteristic venation. That of the CuLicipa and
PsycHopip2 is allied and, with the RuypHips, may at first appear
to resemble the TrpuLips, but a short study will enable the
student to differentiate them without much difficulty. The re-
maining families are not so distinctiveiy characterised, and in
these closer examination is necessary.
Terminology of venation.—As may be surmised, various systems
of venational terminology have been constructed, but, since this
is hardly the place wherein to enter into a discussion of their
respective merits and demerits, it will be only necessary here to
fully describe the system adopted in the present volume. Practi-
cally, it is a somewhat modified form of Schiner’s terminology as
used in his ‘ Fauna Austriaca,’ and as adopted by the principal
dipterologists up to the present day.
Osten Sacken, who, according to Schiner,* used a very old-
fashioned and unsatisfactory terminology employed vy Walker
and others of that period, entirely abandoned it in after years,
and the system accepted by him in his celebrated monograph of
the North American TrpuLip™ (1869) was the basis of all his
subsequent work.
Of other systems, mention may be made of that of Schummel,
mainly because he wrote extensively on TrpuLiIp®, but he named
all the posterior cells backwards, that is, what is now called the
5th was his Ist, and he treated the two submarginal cells as
posterior cells, calling them the 6th and 7th.
* Fauna Austriaca, ii, p. Xxv.
EXTERNAL ANATOMY. 25
The Comstock-Needham system was invented by the former
author and elaborated by the latter. Though it must be admitted
that Needham’s researches into the homologies of the veins, not
only in Diptera, but in other orders of insects also (especially
Neuroptera), are, so far as Iam able to judge, perfectly consistent,
there seems no necessity to alter the almost universally adopted
names of the veins. Moreover, the abbreviations used to de-
signate the veins in this new system of venation, such as, Cs 2,
R 4+5, M 1+2, and so on, can never convey the decisive mean-
ing of terms of obvious significance, such as, costal cell, marginal
cell, Ist, 2nd, 3rd longitudinal vein, &c., all of which by their
very names at once define their position in the wings. Of all
recent systems of terminology I cannot but regard this one as
the least acceptable. However, in spite of wholly disagreeing
with this system of venation, I must accord Mr. Needham every
praise for the excellent series of Tipulid wings published by him,
which has been most invaluable to me during my present studies
in this family.
It must be remembered that modifications to suit special forms
are almost imperative, whatever system of classification be adopted,
for it is obvious that since some wings are replete with veins,
whilst others have very tew, it must be a matter of careful study
to decide which are the veins that persist in these latter cases.
It is not therefore merely a question of an arbitrary and artificial
naming of the parts at caprice.
Osten Sacken may be quoted here with advantage :—‘“ Thus, if
we force upon the Trputip# the terminology introduced originally
in the families of Diptera with a less developed venation, we meet
with inextricable difficulties. But there is no more reason for
doing so than for following the opposite course, adopting a
terminology for the TrpuLip# first and forcing it afterwards upon
the Muscipx. It is perfectly arbitrary at which end of the
system of Diptera we begin to trace out the homologues of the
venation. This study of the homologies has two distinct aims in
view ; the scientific aim of showing that the ground-plan of the
venation is the same in all the families of the order, and the
practical aim of adopting a terminology for descriptive purposes.
We cannot carry out a terminology on solely theoretical grounds,
we will have to vary the details of it according to the peculiarities
of structure occurring in different forms, the main plan remaining
the same.”

The alimentary canal presents behind the cesophagus, an ex-
pansion known as the diverticulum or sucking-stomach,7 the
ventriculum or true stomach lying behind it, with, usually, two
ceca. The heart is of the usual type, but in the more specialised
families has two chambers only. ‘* In the larva of Corethra the
heart is a simple elongated tube without chambers.” The two
main tracheal trunks expand at the base of the abdomen into
conspicuous air-sacs. The two pairs of spiracles of the thorax are
provided with “vocal cords” and it is these that cause the
humming when the fly is on the wing.
The nervous system in the NeMArocEera generally comprises
five or six abdominal ganglia and three distinct thoracic ganglia.
Intermediate forms are numerous between this type and those of
the Muscrip®, in which the abdominal and thoracic ganglia are
united into a large mass in the thorax. A minute structure called
Johnston’s organ, placed in the 2nd antennal joint, is supposed to
contain the auditory nerves.
The internal genital organs consist in the male of two oval testes
with short vasa deferentia, a well developed penis with accessory
copulatory appendages, which are of the most diverse structure
even in allied species of the same genus. In the female the ovi-
positor is remarkably uniform ; there are a large number of egg-
tubes, three spermathecie, paired accessory organs, and no true
bursa copulatrix.
3. Tur Harty STAGES OF DIPTmRA.
The Larva.
The larve of all Diptera are destitute of jomted legs. The
larve of other groups most resembling them are those of the
CURCULIONID& (Coleoptera), but whereas these latter have little
or no power of locomotion, the larve of Diptera can generally
move about freely by means of projections on the body called
pseudopods; or by the aid of short bristles arranged so as to
favour progression, such being present even in completely maggot-
like forms.
The spiracles are also of great aid in enabling us to decide
whether a larva is Dipterous or not.
Schiner counted thirteen segments in the larva, first the head,
then three representing the Fgnahe the remainder forming fe
abdomen. ‘There is, however, no ae! criterion yet
* This is from Williston, after caer

discovered, by which the segments can be numbered, and in many
cases the segments cannot be satisfactorily delimited in the present
state of knowledge.” (Dr. D. Sharp, in Verrall’s “ British Flies,”
vol. v, p. 32.)
Many Dipterous larve have no distinct head. These are known
as ACEPHALA, as distinct from the EucrrHa.a, or those furnished
with a distinct head. The AcupHata include flesh-eating maggots.
The term “ hemicephalous ” has been used by Dufour and others
for those larvee in which the head end is of an intermediate form,
that is to say, not possessing a sufliciently distinct head to be
included in the EvcrpHata; and the majority of the families
appear to fall into this intermediate division. In these cases the
head part is withdrawable within the body, after the manner of a
tortoise.
“Dipterous larve have the last pair of spiracles largely de-
veloped, and they are frequently placed at the actual tip of the
body ; when not at the tip, they are usually placed dorsally rather
than laterally. These are points of distinction as compared with
other orders of insects. When the posterior spiracles are the
only pair that exists, the larva is said to be metapneustic ; when
in addition to these, there isan anterior pair placed a little behind
the head, the larva is amphipneustic; when there are also inter-
mediate spiracles the larva is peripneustic. The frequency of the
metapneustic and amphipneustic systems is characteristic of
Diptera, the peripneustic system being the usual one in other
orders.” (Dr. D. Sharp.)
The Pupa,
The pupa in the OrrHORRHAPHA is “either a free, so-called
mummy pupa, or it remains enclosed in the larval skin, which it
bursts open at its emergence in the form of a T-shaped fissure
on the back, or by an irregular sort of lid at the end of the head.”
( Brauer.)
In the CychorrHAPHA *‘ the pupation always takes place in the
larval skin, which hardens and becomes like a barrel. Previous
to this, the larva possesses on the 4th or 5th front segments, an
arched seam, produced horizontally, and extending above the
mouth, which seam encloses enough of the surface of the barrel
for the emerging flies to burst off as a lid by means of the frontal
bladder.” (Brauer.)
The Habitats.
The habitats of the Diptera in their earlier stages are most
diverse. A large proportion are aquatic (CULICIDH, CHIRONOMIDA,
STRATIOMYID®, TABANID®, EPHYDRIN4®, etc.), some like Eristalis,
in the SyRPHID#, preferring rank pools or drains; quite a large
number live in the earth, as do many TrPuLID#, some THEREVID®
and Empip®; others in rank or rotting vegetable matter,

right side of the insect without removing it from the cabinet.
These minute pins should carry the specimens as near their heads
as possible, and be stuck in neatly-cut, oblong pieces of white
pith or similarly shaped pieces of cork covered with white paper.
These pieces of pith should be broad and long enough to protect
the head and legs to a moderate extent, but no broader, otherwise
it is impossible to place a strong hand-lens near enough to examine
details. Moreover the pith should invariably be of some depth, as this
secures a tighter grasp of the large pin which must be thrust through
the end of the pith opposite that bearing the specimen.r A dot of
white gum placed on the upper side of the pith on the spot where
the small fine pin is inserted will fix it securely and a larger drop
of gum should be placed around the strong pin where it emerges
from the under side of the pith. Some collectors, however,

prefer not to gum the specimen into the pith, so that it can be
removed for closer microscopic examination when necessary. In
the case of the excessively minute forms they should be pierced
from below the body, the point only of the very smallest pin
being inserted so as only just to emerge from the dorsum, the
head end of this pin (there being, as said before, no real enlarg-
ment as a “ head”) being stuck in the pith, but in this case it is
most advisable to gum the pin in the pith, it being much more
likely to fall out when inserted, so to speak, upside down.
For the closer examination of the anatomical structure of very
small Diptera, as PsycHoDID® and all those of still lesser size, it
+s convenient to mount some of the specimens on microscopic
slides, preferably in a more or less dissected state; but this
method has at least one disadvantage, that it frequently destroys
all the exterior characters, such as pubescence, spines, bristles,
all of which are valuable specitic points of difference. So that
unless the species depends solely upon some anatomical structure
quite invisible to the naked eye, it should be identified whenever
possible defore mounting it on a slide, as it is otherwise often
impossible to do so, many of its external characters being after-
wards unavailable. The venation of some of the very pubescent
PsycHopip# is absolutely invisible until the wings are denuded of
the very thick hairs with which they are covered, augmented in
many cases by the addition of semi-opaque imbricating scales.
It is very difficult to determine a single specimen of such a species
unless one wing be broken off and mounted for the microscope,
the other one remaining intact on the dried specimen.
A new process has somewhat recently come to my notice ; this:
is the imbedding of the specimen bodily in an alcoholic solution of
eollodion, with a backing of a mixture of oxide of zine and canada:
balsam, the collodion protected above by a “ cover slip ” of glass,
and the whole mounted on a microseopie slide. ‘The head, wings
and legs are arranged so as to be easily examined and there is no
danger of the specimen meeting with any damage.
This process, although it has the advantage of presenting a
perfectly stereoscopic view when seen under the microscope, has
the serious disadvantage of only one surface, dorsal or ventral,
being visible in any individual specimen; so that unless the
identification of each specimen be done by the collector (who in
very many cases is himself not a specialist) before mounting,
considerable doubt is liable to attach to the specimens from the
inability of the actual specialist to examine both sides of the
same individual. In the cases of very closely allied species known
to occur in the same neighbourhood the positive identification of
a large proportion might be impossible.
The only way of retaining specimens permanently in good
condition * after being properly mounted is by their inclusion in

a well-made cabinet of mahogany, oak or teak; the latter wood
being the only one that will survive the climatic conditions of the
tropics, and even then only in certain regions and with the
greatest possible continual care. In all climates in which there is
much moisture, a small wad of wool soaked in carbolie acid or
creosote must be retained in a corner of each drawer to prevent
mould, and the liquid constantly renewed. Naphthaline, camphor
or creosote must also be kept in the grooves made for this
purpose to keep away mites or similar creatures.
Diptera will keep in excellent condition in temperate climates in
well-made wooden or even cardboard store-boxes, if made with
tightly fitting lids and kept in a dry room.
6. StanpDARD WORKS FOR STUDENTS.
The easiest way in which a beginner can obtain a good insight
‘into the families of the Diptera is to obtain tracings, drawn by
himself if possible, from plates and figures of the wings of a few
of the leading genera of each family (or at all events, of all those
genera that give their names to the families), and then to arrange
them in a copy-book, leaving ample space for additions and notes.
To the wings may advantageously be added the corresponding
antenne and palpi. An even moderate study of these placed side
by side in their systematic sequence, added to the general
appearance or “ facies” of the different families—a perception he
will easily acquire—will give him the quickest preliminary
knowledge of classification possible.
As the soundest introduction to the study of the whole order
there is no work to be compared for reliability and conciseness,
with Schiner’s “* Fauna Austriaca, Diptera,” in two volumes (1862—
1864). The tables of genera are in themselves a mine of
information.
In addition to this work may be earnestly recommended Prof.
Williston’s 3rd edition of his ‘‘ North American Diptera ” (1908).
It is fully up to date, has the advantage of being in English, and
is profusely illustrated by diagrams of wings and other parts of
the body. These two works in conjunction will make the student
acquainted with many hundreds of genera, a large proportion of
which are cosmopolitan or nearly so, Both works are easily
obtained at a moderate price.* For minuteness of detail and the
full history of synonymy in the families dealt with, Mr. Verrall’s
huge work on ‘ British Flies” should, when completed, be the
standard work on the order for the next century. Other works
which are absolutely indispensable to the earnest student,
especially of exotic flies as well as European species, are:
Meigen’s “ Systematische Beschreibung, ete.,” Wiedemann’s “ Aus-
gereuropaische zweiflugelige Insekten,” Macquart’s ‘“ Diptéres

exotiques,” Zetterstedt’s “ Diptera Scandinavie,” Walker’s “ List
of the dipterous insects in the British Museum,” and “ Insecta
Saundersiana,” Bigot’s ‘‘ Diptéres nouveaux, ete.,” Schiner’s ‘ Reise
der Novara” and the “ Biologia Centrali-Americana.” Everything
written by at least Loew, Osten Sacken, Schiner, Williston and
Van der Wulp should be obtained, whilst the works of Rondani
and Robineau-Desvoidy, though less reliable, are always in
requisition. All the writings of living dipterologists should also
be consulted.
7. ESTIMATED NUMBER OF KNOWN SPECIES,
The Diprera, or two-winged insects, may be regarded as
represented by about 35,000 described species. Of these some
portion will, of course, be ultimately relegated to synonymy, but,
even after deleting these, the remainder in all probability
represent but a tithe of those actually existing throughout the
world.
Many regions have been practically unexplored by the collector.
Such parts are the bulk of the South American Continent, where
many thousands must remain to be discovered in the immensely
fertile valleys of the Amazon, Orinoco, La Plata and other large
rivers, and in the teeming tropical districts of the northern part
of the Continent. Africa is at present almost unworked, save for
the Mediterranean shores, Egypt, Italian East Africa and the
Cape; none of these, moreover, having been treated to a tenth
part of the study that has been given to the Diptera of Western
Europe. Australia, judging from what I possess of unnamed
material in my own collection, must. eventually yield a rich
quota ; Skuse, the only writer in that country, gave 10,000 as a
reasonable estimate of the species probably existent there. Besides
these, there are large areas in Asia and even in Eastern Europe
which have hardly been touched by the collector. A very large
number of species must still remain to be discovered in the vast
North American continent, whilst lesser worked regions of the
New World, Mexico, Central America and the West Indies
will certainly double or treble their present lists of species, if
the enormous increase during the past three or four sere in the
known forms of the Oriental Region in such groups as have been
more thoroughly worked, is any criterion.
For instanee, no family has ever been so systematically or
assiduously collected i in such a number of varied districts through-
out the world as have the Cuxicip" during the past ten years or
thereabout, and the enormous increase in the recorded species in
this family (even allowing for a large proportion of synonyms or
varieties only, as was suggested by me a few years ago),* seems
to foretell a grand total throughout the whole order of incredible

maguitude, if other families, as may reasonably be supposed, are
as prolific of new forms as the Cunicrp# have proved.
Schiner in 1868,* in noting that 19,449 species were at that
time known, distributed them geographically as follows :—Europe
8670, Asia 2046, Africa 1644, America 5577, and Australasia
1056, the remaining 516 coming from unknown localities. In
Hardwicke’s ‘Science Gossip,’ fifteen or more years ago, cal-
culating pro rata according to geograpical areas, I estimated
200,000 as a quite moderate estimate of the number of species in
actual existence !
The Palearctic Catalogue, recently issued, gives a little over
13,000 f as inhabiting the Palearctic Region up to the year 1907 ;
Aldrich accumulates about 9000 species indigenous to North
Americat; Van der Wulp’s Catalogue of South Asian Diptera
totalled 2889 up to not later than 1906; whilst a manuscript
Catalogue of my own compiled on the recorded Australasian
Diptera includes about 2000 (up to 1909), to which I am
continually making additions that have been overlooked.
The gigantic Catalogue of the world’s Diptera, by Prof. Kertész,
now in progress, gives a total of about 13,600 species as known in
the families at present dealt with ; that is to say, the Nemarocera
and practically all the remaining families except the Muscrp#
If this last enormous family bears the ‘same proportion in the
world’s species as it does in the Palearctic fauna, it should
comprise 14,000, making a total of between 33,000 and 34,000 as
actually known from all parts of the world.
But since the publication of the two volumes containing the
NeMaAtocerA, something like 500 species of CuLicrpm® alone have
been described, whilst my own labours in this suborder will
result in the erection of considerably over 300 more (including
those in this volume), without touching the CuLicipm, CuiroNno-
MID® and CrcrpomMy1p”®, and these 300, moreover, are from the
Orient alone. Prof. Kieffer has added about 250 species to, the
CHIRONOMID® and a limited number to the Cucrpomy1pa, all
these practically from the Indian Empire only.
To illustrate how small a region has been worked over, ic may be
noted that the Oriental NeEMAroceRA were represented by only
230 species in Van der Wulp’s Catalogue (1896), since which the
number has been increased to 1200 or a gain of over 400 °/,.
Moreover, even this great increase of species has been gleaned from
a comparatively small number of localities, the bulk of them (with
the exception of the Cunicip®) having been collected in three or
four Himalayan districts of quite limited extent (Mussoori, Simla,
Naini Tal and Darjiling) ; Calcutta and its immediate environs ;

CLASSIFICATION OF THE DIPTERA, “yf
perhaps half-a dozen Indian localities situated in the plains (Puri,
Pusa, Purneah, etc.); a comparatively small tract in Travancore,
South India (during one visit only); several localities in Ceylon ;
and perhaps half-a-dozen others in Assam and Burma. These
localities do not represent a tenth part of the Indian Empire even
allowing a fifty mile radius to each. Realising that the Numa-
TocERA themselves only represent a fifth or a sixth part of the
whole order of Diptera, the immense possibilities lying before
the student will be apparent.
8. Tum CLASSIFICATION OF THE DIPTERA,
It cannot be said that there is at present any universally
accepted classification of the Diptera, although most authors are
agreed on Brauer’s primary divisions of ORrrHoRRHAPHA and
Cycborruapnua, and the secondary division of the former into
Nemarocera and Bracuycera. The lesser subdivisions higher
than families, especially amongst the Bracuycura, proposed by
various authors on different groupings of families, are so numerous
that it would be out of place in the present work to give them in
detail, much less to discuss them.
Williston * gives in full Brauer’s, Schiner’s, Osten Sacken’s and
Coquillett’s classifications, in order that the student in his study
“may not reach the erroneous conclusion that any system is
authoritative.” He also gives a classification by a new writer on
this subject, Lameere, but this author has been so severely
criticised that his views are not included here.T
The division into OrrTHORRHAPHA and CYCLORRHAPHA ‘may
perhaps safely be accepted, since all, or nearly all, ares agreed
thereon, though by no means agreed as to their rank and limits.”
Osten Sacken considered that the characters recognised as
distinctive of the Nemavocrra and Bracuycera are of more funda-
mental importance than those distinguishing the ORTHORRHAPHA
and CychorRHAPHA, an opinion from which Williston differs,
accepting Brauer’s primary divisions as the truer biologically.
By far the most pertinent and concise account of the dis-
tinctions between the Nematrocrera and Bracuycrra, and the best
and most elaborate synoptical table of families in the latter
division is that in Mr. Verrall’s monumental work on “ British
Flies.” = Biological notes of paramount importance are given of
each family.
* “North American Diptera,” 3rd edition, p. 52.
+ It seems out of place in the present work to dilate on the classification
of this order as proposed by the very earliest writers. The works quoted may
be consulted by those readers desiring this information.

present published, Brauer’s descriptions of his suborders and higher groups

38 INTRODUCTION,
The subject of the higher systematic subdivisions of the Diptera
has never received from me any special study, so that, perhaps,
opinions on it are out of place, but I have always considered the
Nemarocera and Bracuycera (by which latter I mean all the
remaining families except the EproposcrpEA) as a more natural
classification of the perfect insects than the shutting off of the
Syrpuip# and allied families from the present-day ‘‘ BRACHYCERA,”
and allying them to the Muscids in a common group, opposed to
the NemMaToceRA and present-day ‘“‘ BRacHycprRA” combined.
If the OrrHorrHapHaA and CycLorRHAPHA are recognised as
the primary divisions, it seems to me that the secondary divisions
might be called Nemarocera and OrrHopracHycera, in the
OrrHoRRHAPHA; and CycLhopracHyceraA, Muscorpna (= Mvs-
CID, sensu lato, plus PHortp&®) and Erroposcrpua (or PuprpaRra),
in the CYCLORRHAPHA.
I cannot help feeling instinctively that the most natural
classification is into'two suborders, NEMATOCERA and BRACHYCERA,
the latter divided into two groups, the first containing all the
families exeept the Muscrpm* and PHorip®, which together
would form the second group. The Puprpara might either form
a third group of the Braciycura or constitute a third suborder.
In other words, it seems unnatural to me to separate the
SyrPHIp#, PipuncuLip® and PuLaryprztpm from the families
forming the present-day Bracuycera. The Muscrp® as a whole
seein to form a very compact, homogeneous group, quite different in
external structure, appearance, and habits from the other Brachy-
cerous families, and possessing a typical venation. The aberrant
family PHor1p® seems most nearly allied to the Muscrp™, through
the Borzorin& or some allied group. The unfortanate part of
the primary classification (though possibly biologically correct)
into ORTHORRHAPHA and CyYCLORRHAPHA is that that system
affords no easy clue to the determination of the perfect insects,
since the absence or presence of the frontal lunule is the only
character offered and this moreover is either absent or incon-
spicuous in three families of CycLorrHAPHA in which it should be
present, including the extensive family Syrpuipm. Since be-
ginners certainly never commence their studies with life-histories,
I defy any ordinary entomologist attacking the Diptera as a new
study to sort out into eae respective suborders a box full of
mixed Diptera of mary families. He would therefore inevitably
be compelled to fall back on the old groups of Nemarocera and
BRACHYCERA, eliminating the Syrpuipm, PipuncuLipm, Puary-
pEzIpz, Muscip#, Puortp® and so on, by their respective very
typical systems of venation.
* Tam convinced that the whole of the Muscip should be included in a
single family and that the Tachinids, Anthomyids and so on should rank but
as sub-families, the various Acalyptrate groups each forming a subfamily of
equal rank with them. The Dexids and Sarcophagids would be sunk in
Tacninin&, and the intermediate Calyptrate subfamily would be Muscin™ (in
the old sense),
SUB-ORDBERS OF THE DIPTERA. 39
9. Tur SUBORDERS OF THE DIPTERA.
The majority of authors have adopted Brauer’s division of the
order into ORTHORRHAPHA and CyCLoRRHAPHA, separated mainly
according to the method in which the perfect insect escapes from
the pupa-case. These suborders may be thus characterized :—
Suborder ORTHORRHAPHA.
Diptera in which the pupa-case is “‘ mummy-like,” more or less
indicating the outlines of the imago, as in the common crane-fly
or ‘ daddy-long-legs ” (Tipula).
The fly emerges “from the dried larval skin forming the pupa-
ease through the T-shaped opening which is formed by a
length-wise split on the back, near the head-end, and by a cross-
wise split at the front end of this ; or (rarely) through a cross-wise
split between the 8th and 9th abdominal segments. Adults
without a frontal lunule.
Larva with a ‘“ jaw-capsule” (Kieferkapsel) or more or less
distinct head. Pupa free, or enclosed in the larval skin.
Suborder CYCLORRHAPHA.
Diptera in which the pupa-case is oval or egg-shaped, with a
comparatively smooth surface, bearing no resemblance whatever to
the perfect insect. For example the common house-fly (Musca)
and blow-fly (Calliphora).
The fly emerges from the puparium through a circular orifice
made by the insect pushing off the head-end.* Adults possessing
a frontal Junule.
“The frontal lunule is a small crescent-shaped piece im-
mediately above the antenne, which is characteristic of the
second suborder, the CycLhorrHAPHA. In most of the members of
this suborder there is a suture separating the lunule from that
part of the head above it, the ‘frontal suture’; and {frequently
this suture extends down on each side to near the mouth. But
as the suture is wanting in several families of the CycLorrHaPHA
it is often difficult to determine whether the lunule is present or
not.” + (Comstock, 1895.)
The larva is without any distinct head.
* Tt effects this by means of the ptilinum, a small bladder-like organ situated.
immediately above the base of the antenne, the inflation of which by the
imago springs off the upper piece or cap of the puparium. It is of course
only present in the Oycborrmapaa, since the ORTHORRUAPHA escape from the
pupa-case in another manner.
+ These families are the Syrruip#, PreuncuLin& and PLarypnzip2x.
40 ORTHORRHAPHA,.
The suborder OrrHorRHAPHA is divided into two groups, the
Numatocera and the BracHycura (meaning “ thread-horn” and
‘“ short-horn” respectively), which are distinguished from one
another by the following characters
NEMATOCERA, Latr.
“ Palpi pendulous; generally 4- or 5- jointed, and more or less
filiform. When (as in Aedes and some genera of CECIDOMYID)
there are only one or two joints, the structure of the antenne
and the venation remove all doubts.” (Verrall, “‘ British Flies,”
1909.)
Antenne composed of two basal joints (which are practically
always differentiated from the others and known as the scape)
and a flagellum of several joints (at least 6, generally 8 to 16,
occasionally as many as nearly 40),* which are homologous, that is
to say, closely resembling one another.t They are most usually
oval or cylindrical, not infrequently bead-like, sometimes disciform,
flask-shaped, pectinate or thread-like. The antennee of the male
in many cases (CULICIDM, CHIRONOMID#, CLENOPHORINI, etc.)
differ very considerably in vestiture from those of the female.
Wings with a venation varying from a simple form (CEcrDo-
MyIDM and some CHIRONOMIDA, ete.) to a very complex form
(in most TrpuLip#). Anal cell (when present) wide open,t and
with a tendency to greater width at the wing-margin; as con-
trasted with the Bracuycrra, in which it is, as a rule, closed
before the margin of the wing ; or when open, it is nearly always
narrowed towards and at the wing-margin. ‘The 2nd longi-
tudinal vein often furcate, the 35rd vein rarely.$ Discal cell
rarely present, except in ‘'1rPULID# (in which it is also not infre-
quently absent or capricious, according to the individual) and in
the RuyPHID”. ;
“Tn all cases of doubt as to whether a fly belongs to the
Nematocera, through the palpi being only one- or two-jointed (as
in Aedes or some genera of CrucipoMy1p#), the structure of the
antennze and the venation should remove all doubt. When the
antenne are shortened. and the flagellum (=38rd joint) is appa-
rently only annulated (as in the “BIBIONID®, SIMULIIDM and

+ This term is used here in the same sense as Mr. Verrall employs it in his
classificatory introduction to the second published volume (vol. v.) of his
“ British Flies.” That is. to say, in its popular and ordinary sense of
“having the same relative position, proportion, value or structure, aud not
in its zoological sense, that the hand of a man and the fore-foot of a horse are
homologues.”
id The only exceptions occur in a few Brpionip2#.
< Williston adds, “ if ever.” I have in the present work temporarily
Peco aniaedl a certain forked vein in some genera of Brsionip# as the 3rd and
not the 2nd longitudinal, although haying doubts on the subject; and this
prevents a statement that the 3rd vein is mever furcate in the NEMATOCERA.
ORTHORRHAPHA. 41
Ruyrnip#), then the antenne never bear any terminal style or
arista,* and the venation is either completely distinct from any
of the Bracuyogra, or, if rather similar to that of the Bracny-
cera (as in Rhyphus), the widened end of the anal cell determines
its position, and in these cases the many-jointed pendulous palpi
are distinct.” (Verrall, 1909.)
“ Larve with horizontally biting upper jaws, or with the mouth-
parts quite rudimentary, in which case the larve are peripneustic,
and have 13 segments.” (Brauer.)
BRACHYCERA, Macq.
“ Palpi porrect, not pendulous; 1- or 2- jointed (sometimes
rudimentary); if two-jointed, the 2nd joint is more or less clavate,
and larger than the Ist, which appears to be a handle to the 2nd.”
(Verrall, 1909.)
Antenne composed of two basal joints (the Ist sometimes
almost imperceptible), generally differentiated from the 3rd, but
in many groups, less conspicuously so than in the NEMATOCERA ;
and a third joint, which varies in shape, size and nature to a very
great extent. In most cases it is an obviously solid joint of quite
a different form from that of the basal joints (SYRPHID4, Muscip#,
etc.); in several groups it is, whilst differing greatly from the
basal joints, annulated, that is, marked with fine transverse lines
as though composed of several joints closely compressed (STRATIO-
MYIDE, TABANIDE, CENOMYID®, etc.) ; in others (Asizipm® and
some BoMBYLIID.®, ete.) it is elongate and cylindrical, somewhat
resembling the basal joints but longer. The 3rd joint may or
may not support a style or arista, the latter may be dorsal, but is
more often apical. In cases where the 3rd joint is elongate and
annulated also, thus bearing, to the elementary student, some
resemblance to the nematocerous form of this organ, the porrect
palpi, and especially the yenation, will instantly remove all doubts.
(Such genera are Stratiomyia, Ceenomyia, Hevatoma, etc.)
Wings nearly always with a venation of some complexity, but
in some genera of Empip® and Donicnorrp® it is reduced to
more simple form. Anal cell +, when open, always contracted
near the hind margin of the wing; but more generally closed
before the margin, often at a considerable distance from it. The
2nd longitudinal vein not furcate, the 3rd very often fureate.
* The only apparent exception is in the OrrineruiLip®, an abnormal group
of extremely limited extent, comprising only five known species, and not
known to occur in the Hast. In these flies the flagellum is avistiform. In
Chionex, a wingless Tipulid (not found in the East either), the flagellum ends
in a slender 3-jointed style. For Oriental students, the rule may be considered
to have no exception.
+ T follow Verrall in this, but the beginner is liable to have some difficulty in
recognising this cell in wings of very simple venation.

“In all cases of doubt as to whether a fly belongs to the
Bracuycyra or Nematoorras (and doubt could only arise in some
STRATIOMYIDH and Luprip®), because of an annulated, flagellum-
like 3rd joint at the antenne (asin Rhachicerus, Beris, Xylophagus,
Cenomyia, etc.), the contraction of the anal cell towards the
wing-margin provides an infallible character.” (Verrall, 1909.)

or outwards and downwards, which are used for piercing,
hacking, boring or sucking. Head not fully developed, only

most numerous in temperate climates and altitudes of four or five
thousand feet upwards in warmer regions. They are delicate in
structure and comparatively small or very small in size, for the
greater part obscure in colour, blackish, brownish or yellowish,
rarely with really vivid colours, but often with paler markings.
MYCETOPHILID ©. 45
In the typical subfamily the principal genus, Mycetophila, with
some others, possesses a laterally compressed abdomen, which,
with the hump-shaped thorax and low small head, gives them the
appearance of fleas, the resemblance being further heightened by
the power of leaping to some extent by means of the well-
developed hind legs.
There are no macrochetx in the family, the majority of the
species being almost devoid of all but a microscopic pubescence
and a few bristly hairs on certain parts of the body. The tibiz,
however, are in most cases (except ScrARIN®) furnished with two
or three rows of bristles, which afford good characters for classi-
fication, and also with apical spurs. The coxe are more or less
enlarged, often very considerably so, in all the subfamilies except
ScraRin®, in which they are nearly normal.
‘he imagos are found in shady places in fields and woods, the
larval stages being passed in fungi in a large number of the
species, in rotten wood in many others, whilst a limited number
are aquatic. A few species live in vegetable mould, under the
bark of trees or in cow dung, and many occur in marshy places.
About four hundred extinct species are known, a good
number of these belonging to the more extensive recent genera,
though they appear geologically as early as the Mesozoic period,
in the Purbeck beds.
Popularly they are known as fungus-gnats, from their breeding
in fungi, and it has been claimed that their presence is of economic
value to the farmer by keeping down the fungi which would
otherwise by their numbers injure trees and shrubs.
Some species are said to hibernate and reappear in early
spring when, according to Heeger, they “copulate after a few
days, generally in the evening. After six or ten days, the female,
if the weather is moist and rainy, lays its eggs on the tungi growing
on old horse-chesnuts, singly, twenty or thirty on the same fungus.
The larve hatch after eight or ten days.”
The family characters of the adult Mycetophilid may be briefly
summarised as follows :—
Head small, rounded or moderately elongate ; eyes rounded or
sometimes reniform, separated in both sexes by a broad frons.
Ocelli two or three; when only two, they are placed each
touching an eye-margin ; when three, they may be in the form of
a more or less flattened triangle, or practically in a straight line,
but the middle one is always on the centre line of the frons.
Antenne elongate, of 12 to 16 joints; the scapal or two basal
joints differentiated, the rest generally cylindrical, in some genera
compressed, more rarely pectinate. Proboscis short, blunt; quite
elongate in one or two genera only (Gnoriste is the only Oriental
genus). Palpi of three or four joints, incurved, the Ist very small,
occasionally one joint much more strongly developed than the
others.
46 MYCETOPHILIDE.
Thorax moderately arched, in a few cases conspicuously so ;
scutellum comparatively small, metanotum prominent.
Abdomen elongate and generally cylindrical in the male, pointed
in the female, often laterally compressed in both sexes ; normally
6- or 7-jointed ; often contracted at the base. The male genitalia
are complex and prominent, variable in structure, but less so than
in the TrPuLIp®; the female ovipositor short, not prominent, with
two terminal lamelle.
Legs long, slender and delicate, with the cox as a rule
distinctly enlarged and elongate in all the subfamilies except
ScIARIN®, in which they are more nearly normal. Tibie with
spurs at the tips, and often with two or three rows of bristles
affording good classificatory characters ; femora in some groups
more or less flattened and widened.
Wings comparatively broad, oval or slightly elongate, humeral
cross-vein nearly always present, subcostal cross-vein rarely ;
auxiliary (or ‘‘ subcostal ”) generally short, rarely extending beyond
middle of wing; 1st longitudinal long, the 2nd longitudinal
absent, the 3rd emerging from the Ist generally about its middle
and ending a little before the wing-tip usually at the spot or
very near where the costal vein terminates. The 3rd vein often
forked, the upper branch often short and so obliquely placed
as to appear as a cross-vein (especially m Macrocera and Scro-
PHILIN®, in the latter enclosing an additional cell, by cutting off
the basal portion of the marginal cell).* The 3rd vein in two
groups is coalescent with the 4th for a short distance (Macro-
CERINE, CEROPLATIN®); the 4th longitudinal is always forked,
at varying distances from the base, the 5th also; in both these
veins, one or both the branches may be indistinct on the basal
portion. Posterior cross-vein present or absent, in the latter case
its absence being due to the coalescence (sometimes only puncti-
form or nearly so) of the 4th and Sth veins. Marginal cross-
vein absent ; 7 discal cell always absent; 6th and 7th longitudinal
veins more or less incomplete or indistinct in most genera, in a
few well developed, often one or the other rudimentary or absent.
One genus in this family is wingless.£ In the Scrarinzx the
auxiliary vein is always straight and ending free, never united
either to the costa or the Ist longitudinal vein; the Ist is
moderately long, the 3rd_ begins at a right angle, and the anterior
cross-vein is so oblique, and as a rule long, as to appear in a line
with that portion of it after the bend. The 4th vein is forked at
* Being bounded by the 3rd longitudinal vein, instead of the 2nd, this cell
is technically perhaps the submarginal. I propose the name ‘ Sciophiline
cell” for it, as characteristic of this subfamily.
+ The only doubtful case is Allactoneura, Meij., q. v.
+ Epidapus, a non-Oriental genus. Winnertz says that LF. venaticus, Hal.,
found in Europe, breeds in the rotting stems of Carpinus betule in company

according to its author, is the cause of some disease in the potato, forming
a kind of scab.

varying distances from the base according to the species, and
perhaps too much importance has been placed on this as a
character in classification. The 5th vein is widely forked at the
base, the upper branch sometimes detached; 6th incomplete ;
7th rudimentary or absent.
Life-history.—The metamorphoses of a good many species,
mostly European, are known, but no Oriental species has yet
been studied in the earlier stages.
The eges are laid singly on the underside of a leaf, or on
the pileus of a fungus, but in the case of Sciara they may
frequently be joined together end to end in a long string, and
I have often met with specimens of this genus with such a string
of eggs still attached to the abdomen, from which by slight
pressure further eggs could be made to extrude.
The larva itself has generally the appearance of a very elongate,
sub-cylindrical, semi-transparent, worm-like maggot, of twelve
segments, with a distinct but small head, and yellowish or dirty
white in colour. Osten Sacken’s description of the larva of
Mycetophila may be drawn upon here.
«A distinct horny head; a fleshy labrum, encased in a horny
frame; horny flat lamelliform mandibles, indented on the inside ;
maxille with a large coriaceous inner lobe and a horny outside
piece, with a circular excision at the tip ; labiam horny, small and
almost rudimentary; body fleshy, with eight pairs of stigmata.”
One pair of stigmata is on the first thoracic segment, the
remaining seven on the first seven abdominal segments.
The larva possesses antenne, which in most genera are more or
less rudimentary, but in some (Bolitophila, for example, a non-
Oriental genus) they are distinctly jointed. In some genera ocelli
are present. The means of progression are furnished by rows of
short bristles on the under surface. Most of the larve are
peripneustic.*
Some species spin true cocoons when preparing to pupate,
whilst others construct a rude pupa-case from earthy materials,
Occasionally (Hpicypta, a Huropean genus) the larval skin is
adapted to form a cocoon in which to pupate, but the pupa itself
is free. Itis smooth, with more rounded corners than in the
Tiputrip®, the legs and antenne being generally distinctly
recognisable.
Geographical Distribution.—W orld-wide, from the Arctic Circle
to the tropics in both hemispheres, but most abundant in
temperate regions.
In comparing the Mycrropnttip® as a family with the other
families of NeMAvToceRA, it may be remembered that although the
Scrarinm are usually ranked as a subfamily only of an equal
* Tn at least one non-Oriental species, Mycetobia pallipes, Mg., from Britain
and North Europe, the larva is amphipneustic, that is, it has a pair of stigmata
at the tail-end and a pair on the first thoracic segment.
48 MYCHETOPHILID®.
value with the other subfamilies, they possess two tolerably con-
sistent characters that separate them from these other families
taken together; so that many authors regard this family as
divided into two parts, the Mycetophilid part and the Sciarid
part, the former divisible into several well marked subfamilies, the
latter practically represented by the gigantic genus Sciara alone.
The Mycetophilids, taken in bulk, are nearly always recognisable
from the rest of the NeMArocERA by their much enlarged coxee,
whilst the Sciarids, wanting this particular characteristic, may
be recognised by their reduced venation, in conjunction with the
abnormal obliquity of the anterior cross-vein, which is so parallel
to the longitudinal axis of the wing as to appear nearly always
as the basal portion of the 3rd longitudinal vein. They can
hardly be mistaken for any other group except some CEcrpo-
MYID®, but an absolute beginner might confuse them with a small
Plecia, and from this, the long slender antennz would at once
distinguish them.
In the generic descriptions Johannsen (Gen. Ins., Fase. 93,
1909) has been largely relied on, as the latest cosmopolitan worker
in this group, and his characters have been accepted and generally
copied verbatim, except that the descriptions of the venation are
my own, in order that the terminology may be consistent with
that of the remainder of the present work.

There can be no reasonable doubt of the correct identification of
this species. Walker described it from the ‘ East Indies.” His.
“testaceous stripe on each side” is a thin yellowish line from
above the humerus, running below the lower edge of the dorsum,
nearly to the wing-base.

Genus ISONEUROMYIA, gen. nov.
This genus approximates most closely to Platyura. The
characters are as follows :—
Head : antenne considerably flattened, rather more so than in
Platyura, scapal joints cup-shaped, subequal ; the fourteen flagellar
joints subequal, the last one a little longer, the first much narrowed.
ISONEUROMYIA, 67
at base. Palpi elongate, incurved. Ocelli very distinct, placed on
a vertical protuberance, the outer ones very large, the middle one a
little below the others. Wings with all the veins equally and very
strongly developed, except the almost obsolete base of the 4th vein.
Auxiliary vein ending before the middle of the wing, just beyond
the base of the 8rd longitudinal; subcostal cross-vein placed
just beyond the humeral cross-vein. The 1st longitudinal veiu
thickly spinose with several rows of small spines, the remaining
veins each with a single row of microscopic spines. Posterior
cross-vein in its normal position at proximal end of the coalesced
portions of the 3rd and 4th veins. The 5th, 6th, and 7th veins
equally strong, arising close together near the base of the wing,
this strength of the veins being the chief generic character.
Range. Assam, Ceylon.
24. Isoneuromyia annandalei, sp.nov. (PI. ILI, tig. 5.)
2. Head mainly blackish, frons bare, with blue-grey dusting,
whitish above the antenne, ocellar protuberance blackish. Some
stiff black hairs behind the head. LEpistome and palpi from
creamy white to brownish yellow. Antenne yellowish to reddish
brown, a little blackish in some specimens. Proboscis brown.
Thorax blackish. Dorsum with blue-grey dusting, a median
black (not always very distinct) stripe which may be widened in
the middle and which dies away towards the posterior margin.
Anterior margin of thorax, just below dorsum, light creamy
yellowish, the colour extending narrowly laterally. Sides of
thorax brownish, pleure with white or bluish-white dusting, also
the metanotum. Whole thorax shortly pubescent, some stiff
bristles below the brownish humeri, and on the lateral margins
of the thorax. Scutellum with stiff hairs on the hind margin.
Abdomen black, minutely pubescent, base of each of first five
seements with a somewhat narrow but distinct yellowish band,
which appears snow-white if viewed from in front, last segment
all black. Genital organs small, oval, creamy yellow. Legs: cox
yellowish, with some stiff hairs, black at tips, fore pair blackish
on outer side. Femora brownish yellow, irregularly blackish at
base and tips, with short black hairs, which are generally stronger
on the upper side, giving it a blacker appearance. In one
example all the femora nearly wholly black. ‘Tibi and tarsi
blackish. Wings pale grey, rather glassy in appearance, distinctly
iridescent. All the veins very distinctly brown, and all of equal
strength (except basal part of 4th longitudinal). A brown suf-
fusion towards the wing-tip, darkest on its anterior part,
commencing on the costa, exactly by the upper branch of the
3rd vein, and extending hindwards and outwards in gradually
diminishing intensity, sometimes retaining its dark colour as far
as the hind margin. A narrow brown suffusion over the coales-
cence of the 3rd and 4th veins and along the faint basal part of

from Sylhet, 27. v.05 (Zt.-Col. Hall, type), and four females in
my collection from Kandy, Ceylon, v. and vii. 09 (Z. E. Green).
Apparently the largest known Oriental Mycetophilid.
Subfamily SCIOPHILIN A.
This subfamily is represented by a well-circumscribed set of
species numerously distributed throughout the world and possess-
ing a characteristic cell formed by the upper branch of the 3rd
longitudinal vein being so short, so upright, and placed so soon
after the origin of the vein, as to be almost parallel to the upright
short basal section of the vein, thus enclosing a more or less four-
sided cell, which I propose to term the “ sciophiline cell,” from its
being peculiar to this group. Anterior cross-vein present,
subcostal cross-vein present or absent, posterior cross-vein always
absent, ‘I'wo or three ocelli present, always remote from the eye-
margins except in one (non-Oriental) genus, Hudicrana, Loew.

SCIOPHILA,. 69
Head small, spherical, flattened in front, placed low upon the
thorax; eyes oval, slightly emarginate at the base of the antenna,
almost reniform ; ocelli three in number, arranged in a flattened
triangle upon the broad front or more rarely upon the vertex, the
middle one only slightly smaller than the laterals. Palpi incurved,
four-jointed, the 1st joint very small, the 2nd and 3rd subequal,
the last longer than the others taken together ; antenne pro-
jecting forward, arcuated, somewhat compressed, 16-jointed,
the two basal joints cupuliform, hairy. Thorax oval, highly
arched ; mesonotum long and thickly haired, not setose ; scutel-
lum very small; halteres with short petiole and elongate knob.
Abdomen seven-segmented, cylindrical, somewhat constricted at the
base; hairy in the male, with blunt extremity and small forceps.
Legs moderately long ; the tarsi of the fore legs double the length
or rarely more than double the length of the tibie; the tibie
with spurs and with lateral sete, the fore pair with one or two,
the middle pair with three and the hind pair with four rows, the
inner rows with only few and weak sete. Wings elongate oval,
with rounded base, longer than the abdomen, hairy ; hairs some-
times visible to the naked eye. The costa extends considerably
beyond the posterior branch of the 3rd longitudinal vein, but does
not reach the tip of the wing. The auxiliary vein ends at about
the middle of the wing; the 1st longitudinal is long, nearly straight,
the 3rd originating from it before the middle of the wing and at
a right angle, thence curving gently to the border ; the upper
branch of it is very short, nearly upright or moderately oblique
and placed more or less parallel with and quite close to the erect
basal portion of the vein, so as to enclose a quite small oblong,
square or rhomboidal cell. This cell is characteristic of the sub-
family and may be known as the sciophiline cell,* and the anterior
cross-vein is always at its lower basal corner. The 4th longi-
tudinal vein forked near the base, the 5th forked at or beyond the
middle; the posterior cross-vein absent, 6th longitudinal in-
distinct and incomplete.

Range. Including Lasiosoma, Winn., which Johannsen considers
synonymous, the present genus occurs in Europe, Australia,
North and South America, and the West Indies, but it has not
been previously recorded from the East.
* This is an original suggestion as a name for this cell, which does not
appear to have been previously named, yet reference to it is frequently
necessary. It might technically be considered the marginal cell but it is never
referred to thus.
70 MYCHLOPHILID®,
Life-history. The larve of most species of Sciophila live not in
fungi but on the underside of the pileus, protected by a coarse
webbing spun by them. They are more elongate than most
Mycetophilid larvee, and the pupa is encased in a close cocoon of
silk. A peculiarity of the larvee of some species of this genus is
their vivid luminosity, Hudson mentioning a New Zealand species
which gave out enough light to be easily visible several feet away.
In Kertész’s Catalogue of the Diptera, Lasiosoma is admitted as
a separate genus and Mycomyia (Mycomya), Rond., given as a
synonym of Sciophila. Winnertz’s Scrophila is an incorrect inter-
pretation of the genus, which was established by Rondani in 1856,
and all the species placed by Winnertz in his Lasiosoma fall into
the present genus. Winnertz’s Sciophila= Mycomyia, Rond.
25. Sciophila bicolor, sp. nov. (PI. I, fig. 10.)

and metanotum ; the scutellum also with a row of distinct long
stiff yellow hairs. Abdomen wholly black, rather shining, with
short brown hairs; belly similar. Legs mainly yellow, narrowly
blackish at junction of coxa and femora; cox with moderately
long soft yellow hairs ; hind femora rather broadly black at base
and tip ; tibiz barely darkened towards tips; tarsi black. Wings
pale yellowish, considerably iridescent, the sciophiline cell exactly
square, small, placed immediately below the upper branch of the
3rd vein. Halteres yellow.

present they are placed close together in a triangle, the median
one very minute; proboscis very short. Palpi incurved, four-
jointed, the 1st joint very small, the 2nd somewhat longer, but
shorter than the third, the 4th usually as long as or longer than the
three preceding taken together ; face more or less wide. Antenne
projecting forward, arcuate, longer than the thorax in the male,
subequal in the female, somewhat compressed, 16-jointed, the
scape differentiated, the first two joints cupuliform, setose at the
tip; the flagellar joints cylindrical, pubescent. Thorax highly
arched, ovate ; scutellum small, semicircular in outline, metanotum
‘steep. Abdomen slender, seven-segmented, constricted at the
base, usually somewhat clavate, particularly in the male, de-
pressed behind, in the male ending in a small forceps, in the
female with a short ovipositor terminating in two small lamellae.
Legs: coxe elongate, somewhat setose; legs long and slender;
femora ciliated on the flexor surface ; tibiz with lateral sets, the
fore and middle pairs with two, the hind pair with three ranges,
the inner row particularly delicate. Wings microscopically setu-
lose, somewhat projecting beyond the tip of the abdomen. The
costa ends at the tip of the wing or a little before it. The
auxiliary vein ends either free (sometimes indistinctly), or in
the costa, or in the Ist longitudinal vein. The 1st longitudinal
straight or but little curved, the 3rd beginning at a distinct
angle, thence straight or nearly so. The sciophiline cell of variable
length according to the species. The 4th longitudinal vein forked
at or before the middle of its length beyond the anterior cross-
vein; posterior cross-vein absent; 5th longitudinal vein widely
forked at about the middle of the wing, the 6th and 7th incomplete
and indistinct.
Range. Europe, the Orient, Australasia, North and South
America, West Indies, Africa. It occurs also in Baltic amber and
in recent copal from Zanzibar.
Life-history. Nothing seems to be known of the metamorphosis
of any species of this genus, except that the larvee have been found
in fungi and rotting wood.
The species placed in the Sciophila of Winnertz belong here.
Neoempheria, Os. Sac., is hardly a valid genus and is sunk in
Mycomyia. Two queried synonyms are culled from Johannsen’s
work on this family.

Since the description of the species, the abdomen of the type,
and only specimen, has become detached and lost.
29. Mycomyia tinctipennis, sp. nov. (Pl. I, fig. 11.)
Head yellow; antennal scape brownish yellow, about the
basal half of flagellum yellowish brown, changing to black towards
tip; palpi blackish. TZhorav (somewhat crushed) uniformly
yellowish brown; lighter at sides; pleure rather dark grey.
Dorsum with some bristly hairs, apparently more or less longi-
tudinally arranged. -Abdomen: basal half blackish above, yellowish
below (remainder missing). Leys: coxe and femora pale yellow,
tibiz and tarsi pale blackish. Wings pale yellowish grey; slightly
suffused over distal half; over the cross-veins, enclosing the
sciophiline cell, which is approximately square; faintly also behind
the 5th longitudinal vein. Halteres yellow.
Length probably about 34 millim.
Described from a single specimen from Kurseong, 3. vii. 08
(Annandale).
Type in the Indian Museum.
The thorax is slightly crushed, and the apical half of the
abdomen is missing, so that the sex is uncertain. I would not
have described the species but that the wing markings are
probably sufficient to distinguish it.
30. Mycomyia ferruginea, sp. nov. (Pl. I, fig. 12.)
3 2. Head wholly yellow, except palpi, a narrow line from
above antenne to behind head, flagellum, and eyes, all of which
are black. Scape yellow with some bristly hairs above. Thorax
yellow. Dorsum with four dark brown equidistant stripes, the
outer ones placed nearly on the sides (type specimen). They con-
verge somewhat towards the posterior margin and are joined
behind into two pairs by short cross-lines. In the second example
there is a distinct additional median narrow line between the two
inner stripes, of which in the type there is a trace only near the
fore border. Sides of thorax, scutellum, and metanotum concolorous
in type; paler yellow in second specimen. ‘T'wo distinct dorso-
MYCOMYIA. 75
central bristles, a double row of median microscopic bristly hairs,
and an irregular row (duplicated here and there) of bristly hairs
of various lengths along the black stripes. Some moderately long
bristles about the shoulders and humeri, on the posterior corners
of dorsum, aud several distinct bristles on the lateral margins above
the wings. Small bristly hairs occur here and there irregularly.
Scutellum with two pairs of strong spiny bristles on posterior
margin, Abdomen orange-yellow. In one example (type) there is
a black dorsal stripe of moderate width, with a tendency to
enlargement on posterior margins. _ Whole abdomen lightly
covered with short yellow hairs. Lateral edges of dorsum
narrowly black; belly orange-yellow. In the second specimen the
black colour is not so distinctly in the form of a line, being more
irregular and forming a distinct band on the penultimate segment.
Genitalia in both sexes small, withdrawn. Legs: in type, orange-
yellow (in second example, pale yellow); tibie in both specimens
pale brownish yellow towards tips; tarsi black. Wangs pale grey,
yellowish from costa to 3rd longitudinal vein. Inner cross-vein,
and the upper branches of Ist and 8rd veins distinctly but
narrowly suffused.* A slight darkening at wing-tip, at the
forking of the 4th vein (type) or from thence along the hind
margin (2nd specimen). Halteres yellow.
Length 4-43 millim.
Described from two males in the Indian Museum, one taken by
Dr. Annandale at Kurseong, Darjiling, 3. vii. 08, the other from
Caleutta, 11. ii. 90, and one female from Darjiling, 29. v. 10, taken
by me, also in the same Museum.
In spite of the additional median thoracie line and the slight
difference in the disposition of the black colour on the abdomen,
and the deeper general colour of the type, I believe that the two
specimens are conspecific.
31. Mycomyia trilineata, sp. nov.
3. Head: frons, vertex, back of head and flagellum, black ;
face and epistome, palpi and scape bright yellow. Thoraa, scutel-
lum, and metanotum pale yellowish. Three brown stripes of the
usual pattern, the median one the longest, reaching fore border,
and very narrowly divided. Seen from behind, the stripes, and
also the pleure, have a slight bluish-grey tinge. Bristly hairs, as
in M. ferruginea. The minute bristly hairs of the dorsum, irregu-
larly placed; they also line the edges of the dark stripes, which
themselves are bare. Abdomen: dorsum mainly black, posterior
margins of first five segments broadly yellow ; belly yellow. Sur-
face of abdomen with black hairs which are stronger towards tip.
Genitalia composed of a large dark semicircular plate, the claspers
and appendages slender, yellowish. Legs pale yellow ; posterior
femora with a row of well separated, rather long hairs below;

pale yellowish.
Length 3 willim.
Described from one male and another specimen from Darjiling,
29. v.10, taken by me, and now in the Indian Museum.
In the second specimen, there are two flat spatula-shaped
pieces which may be the female lamellw terminating the short ovi-
postor, but as the organs in this specimen are much withdrawn it
is impossible to be sure of the sex.

Described from one male (type) from Tonglu, Darjiling District,
10,000 ft,, 22.iv.10, taken by Mr. C. W. Beebe; also from a
second male taken by me at Darjiling, 7000 ft., 29. viii. 10.
Type in the Indian Museum.
An additional male has a wholly blackish dorsum to the
abdomen, and the genitalia, though too contracted to be properly
visible, appear to be similar ; some finger-like appendages at least
being visible. It is in the Indian Museum collection, taken by
Dr. Annandale at Kurseong, 22. vi. 10. Though possibly distinct
the three specimens appear to represent but one rather variable
species.

The fact that several genera fall into two or more parts each of
this table proves that a satisfactory classification is still a
desideratum. My own special study of the family is too limited
to Oriental, and a certain number of European, species to permit me
to suggest any wide departure from the classification of Johannsen,
who appears to be the latest authority on the group. Distinctions
like those employed at points 8, 12, 16, and 17 may perhaps be
improved upon when a further knowledge of the world’s species is
attained, no classification being satisfactory that is founded on the
species of one zoological region only. For this reason the order
in which the genera are described herein (which is intended to show
their affinities as nearly as possible) varies from that in which
they appear in this table. The absence of the posterior cross-
vein, in conjunction with the unforked 3rd vein, will easily
distinguish members of this subfamily.

with three broad shining black stripes, the median one reaching
the anterior margin, the outer ones a little shorter; all three
united behind on the posterior margin. Scutellum blackish.
Sides of thorax yellowish, pleure and metanotum dark brown.
Stiff yellow hairs towards the margins of the thoracic dorsum, and
a row of yery small stiff hairs on the median stripe; in addition
there are irregular, short hairs scattered over the whole of the
dorsum. Abdomen black, with pale pubescence, posterior margin
of segments with a dull dirty yellow band; belly similar; genitalia
consisting of several comparatively small pale yellow appendages
enclosed in an outer blackish cup-shaped cavity. Legs pale
yellowish, trochanters and tarsi blackish. Wengs pale: grey ;
venation normal; most of the longitudinal veins extremely
narrowly suffused with brown. Halteres yellowish.

Described from a single male from Mundali, Jaunsa Division,
Dehra Dun District, 9000 ft., 12.v.10(C. W. Beebe).
Type in the Indian Museum.
Owing to the drying of the wings the subcostal cross-vein is
barely visible, but it is present between the auxiliary vein and the
1st longitudinal, about half-way between the humeral cross-vein
and the origin of the 3rd longitudinal.

with a brownish tinge, a few pale hairs; belly similar. The geni-
talia (not easily seen) appear to consist of a dark rather pointed
pair of claspers bearing an elongate yellow finger-like appendage
near the tip, and a peculiar large leaf-shaped whitish scale; there
is also a comparatively small ventral V-shaped blackish plate.
Legs rather bright yellow, base of the femora a little brownish,
tarsi darker. (Fore legs missing, except coxe.) Wangs grey, the
apical third and front border a little darker. Venation normal.
Halteres deep yellow, rather large.
Length 4 millim.
Described from a single male from Darjiling, taken by myself,

Owing to the drying of the wings the subcostal vein is not
apparent, and [ am under the impression that in this species it
may be absent.

elongate oval, shorter than the abdomen, setulose. Costa ends
just beyond tip of 3rd vein. Subcostal cross-vein present, placed
near tip of auxiliary vein which latter ends before or after the
middle of the wing; Ist longitudinal nearly straight, long; 3rd

Range. Europe, Assam; of the only two previously known
species, one is European, the other is from an unknown locality.
Life-history unknown.
“This genus resembles Boletina most closely, but differs in having
longer legs, the fore metatarsi being longer than the corresponding
tibiee, and in a relatively longer petiole of the media,* the petiole
being about half as long as the anterior branch. There are several
undescribed North American species of Boletina which closely
approach Leptomorphus.” (Johannsen. )

Metanotum brown, lighter at the sides. Abdomen rich brown,
shortly pubescent ; 1st and 2nd segments all brown, 3rd, 4th and
5th with a broad basal yellow band, 6th all brown, 7th brown
with a narrow vellow tip. Genitalia very small, yellow. Legs
pale yellow, tarsi brownish; hind femora very slightly brown
at base above, and at tips. Wings pale grey, with microscopic

GeEnoryPE, A. cincta, Meij., the original species.
Head in profile oval, frons arched, with depressed line in middle.
Two distinct ocelli, remote from eye margins, and an indistinct
middle ocellus. Eyes broadly oval, face but slightly arched.
Antennz 16-jointed, as long as head and thorax together, flagellar
joints cylindrical, longer than broad, closely sessile. Thorax not
deep, with sete posteriorly, elsewhere with scales and with appressed
pile, as has also the abdomen; scutellum with two long sete at
the apex. Abdomen somewhat depressed, slender, in both sexes
seven-segmented, in the male with a forceps hidden under the
7th segment; in the female the 7th segment and the lamelle are
very small. Legs: coxe long and robust: all tibia with several
ranges of sete; spurs strong; tarsal joints, particularly the
metatarsi, with numerous setule. Wings narrow, without anal
angle. Costal vein ends just before tip of wing ; subcostal cross-
vein present, some distance before tip of auxiliary vein, the
latter ending at one-third of the wing. he 1st longitudinal vein
nearly straight, the 3rd begins near the subcostal cross-vein at a
very acute angle, nearly longitudinal, the basal portion in a straight
line with the rest of the vein. Anterior cross-vein placed
transversely, that is to say, upright, near middle of wing, a little
before the fork of the 4th longitudinal vein. Marginal
(presumably) cross-vein present, joining the Ist and 3rd longi-
tudinals, placed nearly opposite the fork of the 4th vein.t The
5th vein forks at extreme base of wing, the branches detached ;
the 6th and 7th veins are absent, but a fold in the wing behind
the 5th vein (generally very distinct) appears, unless very closely
examined, like a 6th vein. ‘
Range. A. cincta, the only known species, was recorded originally
from Java, but it seems widely distributed in the East.
Life-history unknown.

t It is curious that de Meijere dues not mention the very distinct (although
yellow, in contradistinction to the dark brown anterior veins) cress-vein
between the lst and 3rd longitudinal veins, placed nearly opposite the fork
of the 4th vein. Over a score of specimens have been examined by me
and itis distinctly obvious in all, if looked for; also in an example identified
by de Meijere himself. It will presumably be the marginal cross-vein, but is
not always easily seen, from a prevailing tendency in this species for the wing
to curl up.

more or less yellowish, rest of flagellum black, antenne as long as
the head and thorax together. Thorax blackish, with very minute
black sete, that in certain lights appear as a dull silvery sheen,
lateral bristly hair stronger. Sides of thorax, scutellum and
metanotum black, seutellum with two long apical curved bristles
that eross one another. Abdomen black, with a narrow basal
whitish band on the segments, very variable in its nature and
sometimes practically absent. Genitalia of male prominent below
the last segment of the abdomen, with two nearly straight claspers,
which have black hairs on the underside and on the innerside are
provided with hook-shaped tips; of female very small, yellowish.
Legs pale whitish yellow; coxe very large, alittle black at base and
tip; femora with the fore pair only a little black at tip, middle pair
broadly black-tipped and hind pair wholly black or nearly so ; tibize
and tarsi blackish, the latter the darker, tibial spurs yellowish,
innerside of fore tibie pale yellowish; the tibie of three very
unequal lengths: the fore pair quite short, the middle pair distinctly
longer but relatively short, the hind pair of normal size compared
with other genera in this family. Wangs pale grey, broadly
blackish at tip, the colour covering about the apical third, the depth
of shade and the extent varying. Venation in accordance with
the generic description.
Length 5 millim.
Described (the female only) from several of that sex in the Indian
Museum from Sylhet, 1.1.5 (Zt.-Col. Hall); Thamaspur, Nepal,
18-20.i1.08; Peradeniya, Ceylon, 10-30. vi.10 and 15. vii. 10
(both Gravely); Semarang, Java (named by de Meijere), %i. and
iii. 06 (Jacobson). In my collection from Peradeniya, Ceylon, ix.
and xii. 09 (Green).
The description, so far as it applies to the male only, is in-
corporated from Dr. de Meijere’s description as I have not seen
a male myself. The author of the species says the sexes are alike,
except that in the female the last abdominal segment is shorter
than the preceding and is dark brown. He also observes that this
species must be akin to Mycetophila obscurata, Walk., described
from Salawatti.
The black body, yellowish white, black-tipped coxee and anterior
femora, and wholly black hind femora, reddish face and base
of antenne, and smoky tips to the wings, make the species a
conspicuous one. The wings show a great tendency to fold up in
all the specimens I have seen.

3d. Head: vertex blackish, face brown, underside of head and
the palpi yellow ; antennal scape and base of Ist joint of flagellum
yellow, rest of flagellum brown. Thoraw yellowish brown, with
short yellow hairs and stiffer bristly hairs around the margins ;
pleure with a slight violet tinge. (Scutellum and metanotum
damaged.) Abdomen blackish, of seven elongated, subcylindrical
segments with yellowish grey pubescence. Genitalia very large,
bulbous, blackish brown, hairy and bristly, with a ventral plate.
Legs yellowish; tarsi barely darker. Wings pale greyish, highly

Length 34 millim.
Described from a single male in the Indian Museum taken by
me at Darjiling, 6000 ft., 1.x. 08.
The middle ocellus is not visible, owing to a slight crushing ot
the top of the head; it may or may not be present. Otherwise,
except the slight damage to the scutellum and meianotum caused
by the pin, the specimen is perfect. ~ Only three species are
known—two fossil ones from Baltic amber, and the third from
Indiana, U.S.A. ; it is therefore interesting to find the genus in
the Himalayas.

nearly to the middle of the wing; Ist longitudinal curved gently
upwards, ending a little beyond middle of wing; 3rd begins at a
right angle (like a cross-vein) from near the tip of the 1st: it is
therefore short, and after the bend runs straight to the wing-

blackish, with pale pubescence on dorsum and longer yellow hairs
along the sides. Belly black, with yellow hairs, yellowish at base.
Of the genitalia two rather large blackish lamelle are visible, with
stiff bristly hairs at their tips. Legs wholly pale yellow, except
the tarsi which are a little darker, and there is a trace of blackish
colour about the trochanters. Wings pale yellowish grey, a little
more yellowish on the basal anterior part. Veins brownish yellow,
venation normal.* Halteres missing.

The yellow thorax and large black side-spots make this species
appear very like Leta arcwata, Brun., but the absence of the con-
spicuous arcuate blackish stripe on the wings at once distinguishes
it.

The variety marginatus, Ann., of argentipes is given a place in
this table of species because it falls in a different primary division
of the genus to that in which the typical form is found, and it
might otherwise easily be mistaken for a new species.

the usual silvery reflections, the dorsum of the thorax being rather
darker than the sides.
Head: rostrum rounded at the tip, stout and elongated.
Antenne normal, with two circlets of flat scales and one
of flattened hairs on the 2nd scapal joint. Palpi five-jointed,
the last the longest. Zhorax much as in P. minutus, the

rounded and slightly clubbed at the tip, nearly as long as the
basal joint of the upper appendages and devoid of chitinous
spines ; ‘ntromittent organ with two elongate, slender valves,
which are truncated at the tip. In the female the appendages
are short and broad, the upper ones not much longer than the
lower. Legs concolorous with the body; anterior femora, tibize
and tarsi all about equal in length, except that the tarsi appear
rather longer ; hind femora longer than anterior pairs, their tarsi
distinctly longer and about equal to the hind tarsi in length.

The species occurs in the Himalayas, between 4000 and 7000 ft.,
Naini Tal and Bhowali, Kumaon district (mms and Lloyd) ;
Kurseong, Darjiling district. Apparently common in both
districts in May, June, and July.

Closely resembling P. minutus but rather longer and more
yellowish. The anterior branch of the 2nd longitudinal vein
forks much sooner than in minutus, and the fork of the 2nd vein
is slightly beyond, instead of slightly before, the fork of the 4th
vein.

equal pair at the tip and the other (in which the two chete are
not equal) on the inner surface about half-way along the joint;
the proximal cheete are blunt, the distal ones pointed. The
intermediate appendages without a ventral lobe, slender, pointed,
with the tip curved; lower appendages shorter than the basal
joint of the upper ones, slender, bearing at the tip a bunch of
long stout bristles ; intromittent organ very slender, the valves
rounded at the tip ; the genital filaments well developed. In the

female the upper appendages are considerably larger than the lower
ones, both leaf-like and rounded at the tip. Zegs mainly concolorous
with body, coxee and trochanters yellowish, extreme tips of femora
with a few minute silvery white scales, more conspicuous than in
P. argentipes. Hind leg two and a half times as long as the
head and thorax; the femur a little more than half as long as
the tibia, slightly longer than the metatarsus, which latter is
distinctly shorter than the other joints together. Wings bluntly
pointed, the hairs on the costal border darker than in P. argentipes ;
1st longitudinal vein ending at two-thirds of the wing; fork of
2nd vein distinctly before centre of wing and of fork of 4th,

Type in the Amsterdam Museum.
Abundant in the jungle at the base of the Eastern Himalayas
at the beginning of the rainy season, large numbers flying to light
at Sukna, 500 ft. Darjiling Hills, on the evenings of July 1st. to
3rd, 1908 (Annandale). It has not been recorded from
any where else except, of course, originally, from Java. This
species may be distinguished rather readily from all other
Indian ones except P. malabaricus (according to Dr. Annandale)
by its dark brownish colour.

intermediate appendage short, blunt, with the ventral lobe
represented by a short process on its ventral margin ; the lower
appendage club-shaped, distinctly elbowed, about as long as the
basal joint of the upper appendage, bearing (in addition to slender
bristles) several chitinous spines at the tip and on the ventral
surface. In the female the upper appendage is long and narrow,
somewhat curved, the lower one less than half as long, straight.
Legs concolorous ; the hind leg rather less than twice as long as
the thorax and abdomen; the femur slightly shorter than the
tibia, which is more than twice as long as the metatarsus, the
latter less than half as long as the femur, shorter than the
remaining tarsal joints together by half its own length.
Wings narrow, bluntly lanceolate. The Ist longitudinal vein
ends at three-fourths of the wing, the 2nd vein forking just before
the middle, the upper branch forking at half its length ; the 4th
vein forking at or immediately before the middle.
Length 23 wmillim.
The species occurs in the southern part of Europe; in the
Indian Empire probably all over the plains. Dr. Annandale has
examined specimens from Rawalpindi, September (C. W. Mason);
Quetta, Chitral, Allahabad, October (4. D. Jims); Rajmahal, on
the Ganges, July; Asansol, February (Paiva); Purneah, Pusa
(Howlett); Madhapur; Puri, Orissa; Calcutta at all times of the
year; Port Canning; Igatpuri, Western Ghats, Bombay, in
November ; Poona; Kirkee; Rambha, N.E. Madras ; Trivandrum,
Pallode and Maddathorai in Travancore in November ; and Pera-
deniya, Ceylon.
Type, the whereabouts of this is uncertain.
The smallest of the Oriental species. It is nearly allied to
P. argentipes, in company with which it is often taken, and from
which it may be distinguished by its smaller size and narrower
wings. Newstead notes that this species, which occurs in Malta,
is extremely active and has the peculiar habit, at any rate when in
captivity, of “‘ whirling round and round with great rapidity, so
rapidly at times as to render itself almost invisible.” Dr. Annan-
dale regards this as a silvery grey species, but according to
Newstead the prevailing colour is dull golden ochreous.

3 Q. Head brownish, varying towards yellowish in individuals,
with concolorous thick bristly hairs. Eyes large, black, emarginate
above; frons narrow. Proboscis stout, elongate ; rostrum with °
upright curved bristles ; palpi five-jointed, 2nd joint more than half
208 PSYCHODID®,
the length of the 3rd, which is a long as the 4th and Sth together.
Antenne with Ist scapal joint short, rather slender; 2nd sub-
spherical, bearing a circlet of about twelve slender, spatulate,
curved scales, and (nearer the base) a circlet of stiff flattened
bristles. Flagellum with three or four somewhat irregular
verticils of stiff fine hairs to each joint; 1st joint double the
length of the 2nd, the remainder gradually diminishing in
length. Zhorav covered with brown, or brownish yellow, thick
bristly hair, with bunches of long, blackish, more or less erect,
curved, flattened, bristly hairs, which exhibit silvery reflections in
certain lights ; these arise from sockets provided with raised rims.
Sides of thorax cream-coloured, conspicuously lighter than the
dorsum, with bristly hairs around the base of the legs only.
Scutellum dark, and, with the metanotum, covered with concolorous
hairs. Abdomen slender and cylindrical in both sexes, closely
covered with blackish bristly hairs, the emargination of the
segments often blackish. Genitalia of male with all the appen-
dages long and apparent; the upper appendages with the distal
joint considerably shorter than the proximal one, bearing five
stout pointed cheete, each nearly as long as the joint, arranged as
follows :—a single cheta at a point about a third of the length of
the joint from the base, a pair of slightly unequal! cheete near the
middle of the joint, and a terminal equal pair; the proximal joint
slightly longer than the last apparent segment of the abdomen ;
the intermediate appendages small, consisting of a stout, bluntly
pointed, dorsal lobe and a small ventral lobe which is a minute
pointed process bearing a bunch of bristles at the tip and attached
to the ventral margin of the dorsal lobe ; the inferior appendages
somewhat slender, laterally compressed, longer than the basal
joint of the upper ones, obliquely truncated, devoid of spines,
covered with stout hairs, which form a dense brush at the tip of
the appendage ; a distinct elbow not far from the base of the
appendage; the intromittent organs are relatively ‘long,
ensiform, consisting of two slender, pointed lateral valves,
between which a pair of long filaments can be protruded. In the
female the upper appendages somewhat widely separated from
the lower ones, which are small, pointed, and claw-shaped.
Legs very long, the hind pair being about three times as long as
the thorax and abdomen together; femora much shorter than the
tibize ; metatarsi in all cases at least as long as the remaining
tarsal joints combined. All the legs with strong reflections
making the tibie and tarsi appear silvery white in certain lights ;
the femora bear narrow flattened spatulate brownish scales and
fine bristly brown hairs similar to those of the body ; the tibic
and tarsi covered with closely impressed angularly bent scales,
and bearing, especially at the joints, slender stiff straight hairs.
Wings narrow, obtusely pointed at tip, nearly three times as long
as broad at the widest part. The 1st longitudinal vein ends just
before two-thirds of the wing’s length, the 2nd forking barely before

the middle, the upper branch again forking before half its length.*
The 3rd vein begins at one-third of the wing, running straight to
the wing-tip, the anterior cross-vein placed at its basal angle ; the
4th vein forks just beyond the fork of the 2nd longitudinal, its
branches being parallel; 5th vein straight, long; 6th sinuous,
long. Basal cell nearly one-third the length of the wing. Scales
are present at the base of the wing only, the whole wing having
an iridescent silvery grey appearance, though the colour may be
best described as smoke-grey ; in many specimens the wings are
practically clear, with pale brownish yellow or yellowish grey
hairs arranged in the usual divaricate method along all the veins.
Length about 2 millim.
Probably distributed all over the plains of India, as it occurs, at
least in Calcutta, at all times of the year. In the Indian Museum,
from Port Canning, Rajmahal (Feb., July), Asansol and Pusa, in
Bengal ; Poona ; Lucknow; Madras; and at Pallode and Madda-
thorai in Travancore State, and also at Peradeniya, Ceylon,
1500 ft.
Types in the Indian Museum.
This species is easily distinguished, except in the case of females
distended with blood, from all other Indian forms by the strong
contrast in colour between the dorsal surface and the sides of the
thorax. In P. himalayensis the thoracic dorsum is darker than
the sides, but the difference is not at all so conspicuous as in the
present species. Tt is found in Caleutta throughout the year
but at times is much more abundant, apparently favouring dark
spots in the basement of houses and bathrooms, being also often
attracted at night by the light of a lamp.
Var. marginatus, Ann.
2. Body rather darker than in P. zeylanicus.
Legs: the hind leg is less that two and a half times as long as
the thorax and abdomen; its femur about half as long as its
tibia, of the same length as the metatarsus, which latter is equal
in length to the rest of the tarsus; cox and femora rather bright
shining pale brown. Wings with the 1s$ longitudinal vein ending
some little way before three-fourths of the wing; 2nd longitudinal
vein forking distinctly before the middle of the wing, the
anterior branch forking distinctly beyond it ; 4th longitudinal vein ~
forking almost exactly at the middle.
Peradeniya, Ceylon ; a single female taken in May.
Type in the Indian Museum.
Although only a solitary specimen is known, this variety 1s
apparently a good one. The venation is rather like that of the
typical form of P. argentipes, but the upper branch of the 2nd
longitudinal vein forks distinctly before the tip of the Ist vein,
instead of approximately below the tip ; the wing also is narrower.
ERS a ee es ee
* The fork of the upper branch of the 2nd longitudinal vein is sometimes
considerably more basal than shown in Dr. Annandale’s figure, and the wings
are not infrequently much less broad.
210 PSYCHODIDA.
If the relative lengths of the joints of the leg are safe characters,
the variety marginatus holds an intermediate position between
typical P. argentipes and P. major together on the one hand, and
the remaining species together, on the other.

3. Body covered with bristly hairs giving a uniform golden
grey appearance, with very strong silvery reflections ; disc of the
wings with a bluish iridescence. Legs sometimes darker than
the abdomen.
Head: rostrum somewhat conical, short, truncated in front.
Byes widely separated, emarginate above. Antenne very long
(it bent backwards they would reach nearly to the tip of the abdo-
men), with seapal joints subspherical, the flagellar ones elongate,
slender, densely covered with soft whitish grey hairs. Palpi with
apparently five joints ; the basal one very short, the 2nd, 3rd, and
4th subequal, each shorter than the 5th. Zhoraxv: in normal
specimens ground-colour brown, with bright conspicuous golden
yellow hair; in the dark variety much as in P. argentipes, though
usually brighter yellow. Abdomen long and slender, the ground-
colour pale brownish yellow, clothed with long recumbent pale
yellow hairs and with tufts of longer, upright ones on the dorsal
surface. Genitalia of male with upper and lower appendages
similar to those of P. argentipes, except that they are more slender
and elongate, the basal joint of the upper appendage being nearly
twice as long as the last apparent joint of the abdomen; the
intermediate appendages devoid of a ventral lobe; valves of the
intromittent organ slender and blunt; genital filaments well
developed. Legs generally concolorous with the body, sometimes
darker. Hind leg two and a half times a long as head, thorax,
and abdomen ; its femur less than half as long as the tibia, and
considerably shorter than the metatarsus, which is longer than
the remaining joints together. Wings moderately broad and
pointed, the hairs nearly whitish grey. The Ist longitudinal vein
ends at two-thirds of the wing’s length, the forks of the 2nd and
4th veins are opposite one another; the fork of the upper branch
of the 2nd vein some distance before the tip of the 1st vein; the
petiole of the 1st submarginal cell half the length of the cell.

PHLEBOTOMUS. 911
Type in the Indian Museum,
A large pale species, rather easily identified by the bright
golden yellow hair on the thorax.
Var. griseus, Ann.
Dr. Annandale describes a variety grisea in which the colour is
uniformly darker, greyish or brownish, from several examples
taken by him in a house at Kurseong, Darjiling district, 4700 ft.,
in June 1910; and he recognised the same variety in the same
house in the following year. Of two specimens in the Indian
Museum, the hair on the thoracic dorsum in one is brownish
yellow, in the other nearly the same as in P. argentipes.
Var. perniciosus, Vewst.
A form described by Newstead as a distinct species from Malta
is, according to Dr. Annandale, only a variety of his P. major, an
opinion in which I am inclined to concur, there being no differ-
ences in either the venation or the male genitalia. It has not
been found in India, but it is well to add the general diagnosis,
which is given in the words of the author :—
“ Male, Colour immediately after death: Eyes black. Thorax
with or without dull red-brown spots; when present they are
arranged in a triangle, and there is occasionally a similar spot
on the vertex of the head. Thorax and cox pale translucent
ochreous; abdomen similar, but sometimes pale smoky grey.
Hairs pallid. Wings faintly iridescent in strong light ; pale drab
in subdued light; costal fringe generally very dark or blackish
grey, though examples with pale costal fringes are not uncommon.
Legs silvery grey, in a strong light presenting a distinct metallic
lustre ; in certain lights also those segments which lie in shadow
appear almost black and show up in marked contrast to those
which are so placed that their surfaces refract the light. In some
lights the under surface of the legs appears distinctly and regularly
speckled, a character due evidently to the regular arrangement of
the scales... .
“ Female, With the palpi, antennee, and legs similar to those of
the male. Wings very slightly larger and broader than those
of the male.”

thorax. Vertex and occiput with long bristly hairs. Proboscis
elongate, rather suddenly narrowed at half its length, tip blunted.
Palpi two-thirds as long as the antenne ; situated beyond the last
of two or three small transverse bulges or folds towards the lower
part of the base of the proboscis. The 1st palpal joint elongate,
cylindrical, slightly bent at base, a little constricted below at the
bend, giving the appearance of a very short basal joint ; 2nd joint

22. Body with dark brown hairs on the thorax, a little lighter
here and there. The abdomen (subsequently lost) seems to have
been covered with small elongate whitish scales which, when
viewed in certain lights, show prismatic colours.
Head: antenne as in P, nigripennis, the pubescence very dense,
lying rather close, so that the outline of the flagellum appears fo
have » parallel sides. Legs closely covered with blackish scales; tips of
tibiz and of metatarsi with a row of white scales, of which there are a
few on the tarsi. Wings very lanceolate and narrow, wholly covered
with closely-placed, overlapping, dark brown scales. It is difficult
to see whether hairs are present on the actual surface of the wing
or not, but apparently (and in all probability) they are present ;
some are present on the veins. The 2nd longitudinal vein forks
considerably beyond the base of the 3rd vein ; the anterior branch
forking again distinctly beyond the middle of the wing, a good
distance beyond the fork of the 4th vein, which occurs just before
the middle of the wing. Wing-border wholly unmarked, bearing
a blackish-brown fringe, darkest on the costa and at the base of
the hind margin ; a small are of nearly snow-white hairs at the
tip of the wing.
Length of wing 2 millim.
Described from a single female (?) in the Indian Museum
from Maddathorai, Travancore State, South India, 16. xi. 08
(Dr. Annandale).
Very distinct from all other species owing to the densely scaled
wings, with snow-white fringe at the tip. The abdomen has been
lost in mounting the specimen for the microscope, after the
description was drawn up, but the length of the insect was
overlooked. It is a small species, the wing measuring 2 millim.
in length. The sex is not quite certain, but was noted originally
as ‘‘ probably female.”

Abdomen: the genital apparatus appears to be a moderate-sized,
bare, pointed, pale yellowish brown appendage, similar to that of
this sex in other species. Legs with livid yellow femora and
tibie, the latter black towards the tips; tarsi brownish black,
covered with close brownish scales. The extreme tip of the tibie,
of the metatarsus, and of the last tarsal joint with a few brilliant
snow-white hairs. Wings with the upper prong of the 2nd
longitudinal vein originating much before the fourth part of the
total length of the wing; the 4th longitudinal vein bifurcates
at about one-fourth of the wmg. Ground-colour dark grey, the
veins with the usual double row of hairs, which are black, giving,
with the long fringe of black hairs around the whole wing-border,
a wholly black appearance to the wing, the surface of which is
covered with hairs placed longitudinally. Some distinct shortly
elongate dark brown scales over the base of the wing. A silvery
white spot formed by a few minute, very elongate, hair-like white
scales, at the tip of all the veins, from the first to the sixth
inclusive, nine spots altogether.
Length 1 millim.
Described from a female, in excellent condition, in the Indian
Museum collection, taken in Calcutta, 5-6. 1. 08.
The general appearance of this species is that of a black Psychoda
with nine snow-white spots on the wing-border and with white
spots on the legs. In certain lights nearly all parts of the body
in turn appear more or less silvery white, including the black
wing-fringe, the femora and tibie, and nearly the whole of the
pubescence on the body; the wings also, in certain lights, present
a beautiful iridescence.
A second example in the same collection, from Sylhet (Lt.-Col,
PSYCHODA, 225
Hall), 8. i. 05, is apparently the same species. The hairs on the
wing are golden brown, and those on the body more brownish
than in the Calcutta specimen, whilst the white scales cover the
whole of the metatarsus. The antenne are missing, and there
are a few white, elongated, hair-like scales in the centre of the
wing towards the base. The wing-fringe is golden brown on
the distal half and black on the basal part of the costa and
on most of the posterior margin.
In a note appended to the original description is mentioned a
specimen from Sylhet with a few remaining white scales on the
surface of the abdomen near the base, but closer investigation
reveals that they must have become accidentally attached, forming
no part at all of the insect’s vestiture.

2. Body pale brownish yellow, entirely clothed with long, pale
brownish yellow, bristly hairs, with some concolorous elongated
scales, and with a few black bristles here and there. The bristles
are long, and become scale-like on the dorsum of the thorax and
towards the tip of the abdomen, where, in the latter case, the
black bristles are also more numerous.
Head: eyes black, with dense, soft, pale yellowish grey hairs
between them. Antenne sixteen-jointed; first joint of scape
cylindrical, second spherical; flagellum of fourteen elongated,
pear-shaped joints, each surrounded by numerous long hairs in
the form of a rather irregular verticel. Legs with numerous
bristles, which are very long on the tibize, which, in addition, have
short scales of the same colour lying rather close, and a circlet of
rather long, scale-like bristles at the tips. The metatarsus, which
is nearly as long as the four remaining subequal joints together,
has a few irregular bristles, and the tarsi are covered by close-
lying, pale yellowish white scales, giving a whitish appearance in
certain lights. Wings: the upper prong of the 2nd longitudinal
vein forks near the base, before one-third of the wing, and the
4th longitudinal vein forks at exactly one-third. All the veins
seem to bear the usual double row of hairs, and the intervening
spaces are also covered with brown hairs rather thickly ; there is
a patch of black hairs at the tip of all the veins from the 1st to
the lower fork of the 4th (inclusive), with a trace of a patch
at the tip of the 5th; and a patch of white hairs appears between
all these black patches, so that the border of the wing appears
spotted alternately black and white, and is fringed along its entire
length with close, long, light brown hairs. The hairs of the wing
appear lighter or darker in different specimens, according to the
direction in which the light falls on them, a brilliant iridescence
being at times visible.
Length 13 millim.

Type in the Indian Museum, from Sylhet, 30. i. 05 (Hall); the
second specimen was from the same locality.
Described originally from three specimens supposed to represent
this species; but the one mounted on a microscopic slide, which
bore the scales at the base of the wing, was afterwards found not
to be P. distincta.
In the type-specimen (the only one now existing, as the
one dated 1. i. 05 has been accidentally destroyed) there is
absolutely no trace of any such scales, either at the base of the
wing or elsewhere on it, with the exception of the very small
ones that compose the wing-margin spots.

9. Body covered with blackish hairs, the thorax covered with
bright yellowish brown hairs.
Head: antenne with the pubescence rather closely compressed,
as in P. nigripennis. Legs brown, normally scaled and pubescent.
Wings with dark brown and blackish hairs covering the surface as
well as the veins. Two inconspicuous and incomplete narrow
transverse lines passing across the wing similar in position to
those in P. transversa, composed of light brown or yellowish
brown hairs, placed in small sections. ‘Two distinct black spots
near the base of the wing, composed of stiff erect long black
thickened hairs, one spot on the base of the 2nd vein just before
the fork, and the other on the anterior branch just beyond the
fork. The wing-fringe is greyish, with blacker sections here and
there ; the hairs are also darker along the costa.

bristly hairs.
Head with the antenne as in P. nigripennis. Legs blackish,
with the tarsi showing a lighter shade in certain lights, the tips
of the joints with small pale scales. Wings densely covered with
blackish hairs situated over the entire surface as well as on the
veins. No hair-spots or scale-spots at the tips of any of the
veins, but two narrow transverse bands composed of elongated,
thickened (almost scale-like) greyish white hairs, the first placed
just before the middle of the wing, the second just beyond three-
fourths of the wing; both bands extending from the costa to the
hind margin.

Described from a single specimen, which is apparently a female
(the genital organ not being clearly visible), in the Indian Museum,
trom Kurseong, 4700-5000 feet, 20. vi. 10 (Dr. Annandale).
The two conspicuous transverse bands of grey stiff hairs on
the wings immediately distinguish this species from all other
Oriental ones.

Psychoda hirtipennis, Brunetti, Rec. Ind. Mus. iv, p. 300 (1911).
@. Body brownish yellow, with yellowish brown or brownish
grey hair varying both in shade and intensity.
Head with the antennz practically as in P. nigripennis. Legs
with light brown scales, tarsi not obviously lighter, except when
viewed in certain directions. Wings lanceolate, the brown hairs
covering the surface and placed mainly longitudinally ; no regularly
divaricate rows of hairs on the veins. Some erect bristly hairs on
the basal fourth of the wing. :
Length about 14 millim. :
Described from several specimens in the Indian Museum pre-
senting the following data: Kurseong, 5, ix. 09 (type), Bangalore,
15. x. 10, Maddathorai, 18. xi. 08, Trivandrum, 12-13. xi. 08
(Dr, Annandale); Calcutta, 27. xi. 10.
One example of the above series (from Maddathorai) varies
more than the others by having browner legs, brighter brown hair
on the thorax, and a tendency to patches of darker hairs on the
wing, with light greyish reflections here and there. The specimen
seems to come within the probable specific range of P. hirtipennis,
which is certainly of variable nature.

@. A dark brown species with dark brown wings and con-
spicuous white spots on the legs. Wings with black and white
spots near tips of veins. Body clothed with thick blackish brown
hairs, with which are intermixed on the thorax some fan-shaped
tufts of whitish grey hairs.
Head with white bristly, almost scale-like hairs on vertex, and
bristly black hairs on trons and face. Antenne with very elongate
flask-shaped joints, verticillate as in P. bengalensis; scape with
milk-white elongate scales ; chate present on flagellum, but small,
curved, not S-shaped; pubescence of flagellum greyish white.
Legs with light brown scales and some bristly hairs; knees nar-
rowly but distinctly white, through the presence of a few snow-

veins; black bristly hair-spots at tips of practically all the veins ;
some white scaly hair-spots near tips of some of the veins, and a.
few on each of the two lower branches of the 2nd longitudinal
vein and both branches of the 4th vein, all placed at a little before
their tips; a larger white scaly hair-spot near the base of the
costa, and some isolated erect white hairs placed irregularly here
and there on the veins. The 2nd longitudinal vein forks imme-
diately beyond the base of the 3rd vein, the upper branch of the
former forking barely beyond the middle of the wing, and very
little beyond the fork of the 4th vein.

the costal border clothed nearly to the tip of the wing with stiff,
black, bristly hairs; along this border, at short regular intervals,
one or two small white scales; towards the tip of the costa the

3 Q. Body entirely clothed with hairs, varying from yellowish
grey to whitish, and of a nature varying from soft long hairs to
bristly ones, which latter on some parts, and around the tip of
the abdomen, are distinctly scale-like; in certain lights some
of the scale-like bristles appear blackish or even wholly black.
Head: eyes black, with very large facets; frontal groove very
narrow, with long greyish hairs ; lower part of head covered with
long hairs. Antenne fifteen-jointed; scape of two larger egg-
shaped joints; the flagellum of ten joints of nearly uniform size,
each shaped like a long-necked flask, and three further very minute
joints, invisible except under a microscope. Each joint of the
whole antenna bears a rather thick verticel of hairs. Palpi of
four joints of equal length, with some hairs; last joint very thin,
pointed. Abdomen: the genital process of the male with superior
appendages consisting of two subequal joints, the proximal joint
cylindrical, often concealed in a vertical position in the body,
distal joint sickle-shaped, its ventral edge being somewhat sinuous.
Inferior appendages very long, arising from an elongated, broad
ventral plate; themselves sickle-shaped, clothed with long fine
hairs at their base, and bearing very minute straight bristles on
their ventral surface, each appendage terminating in a single,
short, flattened, almost triangular spinule. The ovipositor of
the female consists of a pair of very small, pointed, chitinous
appendages, which it is somewhat difficult to distinguish amidst
the hairs. Legs of the same colour as the body, clothed rather
thickly with concolorous scales and with numerous black bristles,
the former being thickest on the tibize and tarsi. Wings with
all the veins bearing a double row of hairs, pointing respectively
anteriorly and posteriorly.* The fork of the upper prong of
the 2nd longitudinal vein originates a little before the middle
line of the wing; and the fork of the 4th longitudinal vein
originates a little behind this middle line, but the linear space
between the two forks varies in different specimens. A few black
bristly hairs, forming a small black spot, occur at the tip of each of

the four veins above the 3rd longitudinal (which is unmarked) ;
also at the tip of the upper prong of the 4th, and at the tips ot
the 5th and 7th. These black hairs gradually become more
scale-like towards the last spot, which is usually the deepest
of all.* The whole border of the wing is thickly fringed with
long blackish grey hairs, which extend over the tegule also.

Psychoda albopicta, Brunetti, Rec. Ind. Mus. iv, p. 296 (1911).
Q. Very near P. distans, but differing from that species by
very distinct though small white scale-spots at the tips of most
of the veins, including the 3rd vein. A conspicuous bunch of
black scaly hairs at the fork of the anterior branch of the 2nd
longitudinal vein and the fork of the 4th vein. Some of the
black hair-spots at the tips of the veins are much less distinct
than in P. distans. Fringe of wing dark brown on costa, lighter
brown on posterior margin, the whole appearing golden brown in
certain lights. The hairs on the wing are brown, darker towards
the base. The body is dark, with brownish yellow hairs, which
are darker brown on the thoracic dorsum, and almost yellow in
places. Antenne brown, flagellar joints flask-shaped with long
necks, the verticillate hairs widely expanded. Long sinuous
cheete distinctly present. The tips of the tibie and of the
metatarsi with a narrow circlet of white scales; the legs mode-
rately dark brown.

distinct elongate brown scales on the basal fourth of all the veins.
The wing is lanceolate in shape, the entire margin very distinct,
the costal fringe blackish, but appearing lighter if viewed from
certain directions; the fringe of the posterior margin light
greyish. The 2nd longitudinal vein forks distinctly beyond the
base of the 3rd vein, the anterior branch forking immediately
before the middle; the 4th vein forks distinctly before one-third

3 2. Body yellow, wholly covered with greyish brown hairs,
which in certain lights appear whitish.
Head: eyes jet-black, facets very large. Antenne: basal joints
short and not broader than the flagellum, yellow, with some black
bristles ; second joint spherical; flagellum of fourteen joints, of
which the first ten are flask-shaped (as in P. bengalensis); the
eleventh has no “neck,” and is roughly ovate; the twelfth,
thirteenth and fourteenth are very minute, the two former cup-
shaped, the terminal joint spherical. The verticels of greyish-
white hairs on each joint are very thick, lying closely, directed
forwards and clustering together, thus giving the antenna the
usual solid appearance, with parallel sides, of a grey colour,
marked with small black round spots. Palpi of four hairy elon-
gated cylindrical joints, of equal length, except that the fourth
is slightly longer and pointed at the tip. Abdomen: genitalia of
the male very similar to those of P. bengalensis, but the inferior
appendages decidedly shorter. In the female they consist of a
very concave (on the upper side) leaf-shaped appendage, bending
backwards, but the appendage probably consists of two symme-
trical blade-like halves as in the other species. Legs pale blackish
brown; the femora with some white hairs below, the tibiz rather
closely covered with snow-white hairs, the tarsi blacker, with
white hairs which, towards the tip, are replaced by small elongated
white scales. Wings having the appearance of being pale blackish,
but really pale grey, wholly unmarked; the veins distinct, each
with the usual double row of hairs, which appear black when
viewed from above, but which appear white when viewed horizon-
tally from the tip of the wing. Fringe longest on posterior
border, grey, appearing dark in some lights and nearly white in
others. Wings with a purplish iridescence.
Length 2-13 millim.

Pusa collection from Pusa, 16-17. xii. 08.
Types in the Indian Museum.
In a specimen from Calcutta (3. vi. 08) there is a slight but
distinct spot of black hairs at the tip of each of the veins, and the
PSYCHODA,. 233
tarsi are more densely covered with white scales. L[t may possibly
be distinet, but I can detect no other differences of value.
Several specimens recently acquired by the Indian Museum
through the generosity of Mr. C. W. Beebe, are in all probability
this species, taken by that gentleman ten miles south of Kuching,
Sarawak, Borneo, 25. vi. 10. Being mounted on microscopic
slides their absolute identification is impossible, in the absence of
any previous examination.
The species has been bred in Calcutta from a partially dried
freshwater sponge from the edge of a garden pond.
At Kasauli, Dr. Annandale found the species common in
bungalows on the date given. He has also taken it on mossy
walls and at light in Calcutta.

Psychoda fulvohirta, Brunetti, Rec. Ind. Mus. iv, p. 297 (1911).
2. Body covered with blackish grey hairs, with the exception
of the thorax, where the hairs are conspicuously bright yellowish
brown, those of the alule being more yellow.
Head: antenne as in P. nigripennis. Legs blackish, without
any ornamentation. Wings with the appearance of those of
P. nigripennis. The 2nd longitudinal vein forks distinctly beyond
the base of the 3rd vein, and its anterior branch forks a little
beyond the middle of the wing, very considerably beyond the fork
of the 4th vein, which occurs towards its base; the 3rd vein is
gently bisinuate. The hairs on the wings are blackish grey, those
towards the base being blacker, and those of the posterior marginal
fringe somewhat greyish.
Length 13 millim.
Described from two females from Darjiling, 7000 ft., 7. vii. 09,
type (Paiva), and Kurseong, 26. vi. 10 (Annandale), both in the
Indian Museum.
The bright yellowish brown colour of the hairs on the thorax
makes this species easily distinguishable from all others except
those specimens of P. margininotata with similarly coloured hairs,
but from that species the wholly unmarked wing and unornamented
tarsi will readily separate it.

small coalescing subspherical ones. The antenne have the
thickened appearance uoticeable in P. nigripennis. Legs pale
yellow, with a few irregular black bristles; hind femora with a
row of long bristles, and hind tibize with two rows of long bristly
hairs. Tibie with a few black spines at the tip. Wings distinctly
lanceolate, pale grey ; the veins bearing the usual blackish grey
hairs, with a wide transverse band (composed of erect light brown
hairs) across the centre of the wing, and the apical portion of the
wing is also broadly covered with similar brown hairs; at the
base of the wing is a space covered with erect, soft, white hairs,
and some traces of a similar patch towards the costa between the
two areas of brown hairs. Fringe of wing on costa brownish grey,
on posterior margin more grey or whitish. The fringe of the
wings is darker on the section contiguous to the brownish band
of hairs, and also in the neighbourhood of the wing-tip. A good
specific character is the curved nature of the middle veins of the
wing (2nd, 3rd, and 4th with their branches), which distinguish
it to some extent from its nearest allies, P. nigripennis and
P, fulvohirta.

Pericoma, Walker, Ins. Brit., Dipt. iii, p. 256 (1856),
GunoryPu, 7'richoptera fasciata, Mg.; by designation of Coquil-
lett (1910).*
This genus closely resembles Psychoda. The antenne are
16-jointed, the palpi 5-jointed, and the 3rd longitudinal vein ends
below the wing-tip, instead of exactly at the tip as in Psychoda.
The tegule or squame are much more highly developed.
As in the preceding genus, there are often small spots, formed
of scales, on many parts of the wings and legs, and occasionally
on other parts of the body. The wing-surface is usually clear of
hairs, but in some species it is closely covered with them in
addition to the hairs on the veins. Small specific differences in
the relative positions of the veins occur, as in Psychoda. The
genital organs in both sexes are similar to those in Psychoda.

Life-history. The larve live in fungi or rotting vegetable
matter. The imagos inhabit similar situations to those in which
Psychoda is found.
The life-history of a European species (Pericoma canescens, Mg.)
has been studied. The larva is about
8 millim. in length, 11-segmented,
cylindrical, but tapering at each end.
Head small, free moving, with well-
developed mouth parts. Thoracic
segments distinct; the abdominal
segments rather closely compressed,
approximately subequal in length, each
(except the last one) with three trans-
verse marks on the dorsum. Under-
side of thoracic seements with some
transversely placed bristles; six on
the Ist segment, eight on the 2nd and
four on the 8rd. The abdominal
segments 1 to 7 bear in the middle
two small thickened chitinous plates ;
all the segments furnished with bristly
hairs,

Subfamily PTYCHOPTERIN &.
Latterly, this subfamily has been elevated by some authors to a
distinct family, as in the recently issued ‘“ Palearctic Catalogue ”
and in the ‘Catalogue of Diptera” by Kertész, at present in
process of issue; but to the writer it seems inseparable from the
TIPULIDA.
The Prycnoprerin”® form a very compact group, differing in
two strong characters from the whole of the rest of the Trpunipm.
These are the indistinctness of the transverse V-shaped suture on
the mesonotum, and the absence of the 6th longitudinal vein.*
In Ptychoptera itself there can be little doubt of the short
curved vein present being the 7th and not the 6th. In Bittaco-
morpha this vein is not so curved, but its position in the wing
and distance from the 5th makes it evident that this vein is also
the 7th. Butin Idioplasta, Macrochile and Tanyderus the general
position of the one vein present behind the 5th, its comparative
approximation to the 5th and its usually nearly straight course
makes it quite possible that in these three genera the vein present
may be the 6th, instead of the 7th. There seems nothing
illogical in the 6th being absent in one genus, and the 7th in an
allied genus, considering the great abnormality shown by the
venation of these three genera. The fact that in the typical and
most extensive genus in this subfamily (though in itself com-
paratively limited in number of species) the vein present is.
obviously the 7th and not the 6th justifies the assumption, in the
absence of stronger evidence to the contrary, that the vein present
in the abnormal genera is the 7th also.
The principal genus Ptychoptera is further distinguished from
practically the whole of the rest of the Trputip™ by having the
3rd longitudinal vein forked, and this feature, in conjunction with
the presence of only one vein behind the Sth, renders the genus
easy of recognition. The auxiliary vein in Ptychoptera ends ip
the costa, with no subcostal cross-vein uniting the auxiliary vein
with the 1st longitudinal. +
* T am convinced by its general position and especially by its habit of
turning in suddenly to the wing-margin, that the vein that is present is the
Tth and not the 6th, being in this view supported by Osten Sacken and by
Schiner (Fauna Austr. ii, p. 495), who both leaned to the same opinion;
Williston, usually so correct in the terminology of the venation, being I think
incorrect in considering it the 6th. It is therefore the 6th vein which is
absent in this subfamily; the 5th is obviously present in its usual place,
connected with the 4th by the posterior cross-vein.
+ It has been necessary in explaining the above point of view, to mention
genera not known from the Orient, but at least one species of Zanyderus is
Oriental.
t{ In some genera, however, the subcostal cross-vein is present, as, for
instance, in Protoplasta, Idioplasta and Tanyderus, its position in these being
similar to that in the Lrrnopuna. These genera are not Indian, but Zany-
derus occurs in Amboina.
i“
PTYCHOPTERA, 279
In the practical absence of the peculiar fold in the wing which
I have elsewhere termed the “ obliterative streak,” passing from
the stigma to beyond the discal cell, the PrycHorprerin® approach
the Lrmnoztin®. In possessing sixteen joints to the antenna,
this subfamily also agrees with the Limnosiin», but Ptychoptera
and at least one other genus (Bittacomorpha) possess a slight pro-
longation of the epistoma into something like the nasus of the
Tiputin®. Ptychoptera also rests with its wings divaricate, as
do most of the latter subfamily.
The difference in the number of the antennal joints is com-
paratively unimportant, considering the variation in this character
which occurs amongst the LIMNOBIIN 2.
In venation the PrycnHopreriy® show considerable variation.
A discal cell is sometimes present (Idioplasta, Os. Sac., Tanyderus,
Phil., Macrochile, Lw.), or absent (Ptychoptera, Mg., Bittacomorpha,
Westw.). One genus (/dioplasta) has no less than six posterior
cells, the normal number in the subfamily, however, being three
or four.
Beyond Ptychoptera (of which only three species are known
from the East) only one other species of this family is Oriental—
Tanyderus ornatissimus, Dol., from Amboina.
The larval characters of the PrycHoprerin & have been investi-
gated by Brauer,* and that biologist considered that as the head
of the larva is not imbedded in the thoracic skin, as is the case in
the rest of the Treurip, it is justifiable to separate the group as
a distinct family. Osten Sacken has also referred to the same
subject.f

Life-history. The larva of Ptychoptera is whitish in colour, very
attenuated, of thirteen segments, including the head, with a long
PTYOCHOPTERA. 281
slender tubular tail. The head is hard and small, bearing a pair
of eye-spots and furnished with two very minute antenne, which
are almost imperceptible. It moves by means of the stiff bristles,
directed backwards, affixed to the rather enlarged posterior rim of
each segment ; in addition, there are three pairs of pseudopods or
pro-legs. It breathes through the tail, lying near the surface of
the water (sometimes floating at full length on it) of shallow pools
or brooks, preferring stagnant and muddy water. It is said to
live, during the greater part of the year, imbedded in the mud of
such places, with usually only the tip of the tail projecting.
The pupa is furnished with a long respiratory tube, and floats
on the surface of the water during spring and summer. The
abdomen is provided with five circles of fine spines, by the aid of
which the pupa peregrinates to firm ground just before the
emergence of the imago.
Several of the older authors have left records concerning the
life-histories of some of the European species of this genus, in
particular De Geer, Réaumur, and Lyonet ; whilst, more recently,
the early stages of Ptychoptera lacustris, Mg., have been described
by Beling,* and those of P. contaminata, L., by Grubben.t Brauer

Normally Ptychoptera should have 16-jointed antenne, but the
3rd joint in this species is as long as the next two together, and
occasionally it appears as if two joints were present, but a careful
examination convinces me that it is single. In most of the speci-
mens the whole antenne are certainly present and undamaged.
The species, however, cannot possibly be removed from this
genus, it being in every character a true Ptychoptera.

Subfamily TIPULIN A.
The Tirunin® are distinguished by the auxiliary vein ending
in the 1st longitudinal vein, and not in the costa. The humeral
cross-vein, close to the base of the wing, is the only cross-vein in
contact with the auxiliary vein, the subcostal cross-vein being
wholly absent. The Ist Jongitudinal vein nearly always turns
down into the 2nd and not upwards into the costa, the end of
the vein becoming much attenuated towards its tip. A small
cross-vein, which I propose to call the costal cross-vein, connects
the Ist longitudinal vein near its tip with the costa. The
2nd longitudinal vein has a short anterior branch that is nearly
perpendicular, and this joins the costa just beyond the costal
eross-vein, thus forming a small characteristic cell, known
as the rhomboidal cell “(at first called by Osten Sacken the
trapezoidal). This cell is absent in Dolichopeza owing to the
2nd longitudinal vein not being forked. The lower branch
of the 4th longitudinal vein forks at the inner end of the
discal cell, a little before it or towards the middle of that cell,
never beyond it; the upper branch forks beyond, or at the
earliest, in contact with the distal limit of the discal cell.
The first longitudinal vein forks just after quitting the posterior
cross-vein ; this causes the ultimate posterior cell in such cases
to be pentagonal in shape, its inner end being always pointed.
The diseal cell is nearly always pentagonal or hexagonal.
A peculiar character nearly always visible in the TrruLina,
but especially noticeable in the genus Zipula, is what may be
termed, for want of a better name, the “ obliterative streak,”
running from the neighbourhood of the stigma nearly straight
across the wing, crossing the discal cell somewhere on its basal
half or about its middle, and disappearing soon after quitting
that cell. Osten Sacken refers to it as a “fold” of the wing.
Its effect is partially to obliterate, or at least to weaken, the veins
with which it comes in contact, and its course is emphasized by
TIPULIN A. 285
the actual ground-colour of the wing within its track being dis-
tinctly paler. This peculiarity is indistinct or absent in most
species of Pachyrhina, and seems to be practically absent in the
LIMNOBIIN 2.
The proboscis is distinctly produced, and the tip on its upper-
side is again produced more narrowly, forming what is known as
the nasus or nose. This is especially prominent in the two
leading genera Zipula and Pachyrhina, which in themselves coni-
prise the bulk of the species in the subfamily. It is, however,
reduced to an obtuse projection with a tuft of hairs in Ctenophora,
Pselliophora, and Dolichopeza. Its presence is variable, being dis-
tinct in Scambonewra and Megistocera (both Oriental genera, with
two and one species respectively), also in Brachypremna, an
exotic genus.
The neck, though not conspicuously narrowed, is very distinct
in Tipula, Pachyrhina and Brachypremna; short in Scaimboneura
and Megistocera; almost absent in Ctenophora and Pselliophora,
and quite absent in Zanypremna.
The frons is smooth or greatly arched (7%pula), sometimes
gibbous (Pachyrhina, Ctenophora, Pselliophora).
The antennal scape is composed of a long cylindrical 1st joint,
a quite short 2nd joint which is never (so far as I am aware)
broader than either the 1st scapal or 1st flagellar joints as is so
frequently the case in the Limnosin®. The flagellum is very
varied in construction, sometimes pectinate in the male (Cteno-
phora, ete.) or subpectinate (various genera); serrate, as in some
species of Zipula, or cylindrical, or with ovate joints, as in the
majority of species of both Zipula and Pachyrhina. In a tew
genera it is extremely elongate and filiform, as in Megistocera, in
which genus its length in the two sexes often varies in the same
species, the male possessing an excessively long antenna, the
female one of normal length. The flagellar joints are verticillate
in the T1puLINtI, but not so in the CrHNOPHORINI.
There are several genera with peculiarly constructed antenne,
more or less pectinate in nature, which, not being Oriental, need
not be discussed here ; yet it is as well to note that these abnormal
forms are by no means uncommon in this subfamily, mostly
coming from South America and Australia. Many of them
represent intermediate stages between Ctenophora and Tipula.
The extra length of the leg is generally considered as one of
the characters of the Tirurin”®, as contrasted with the LimnNo-
BIIN®, but it is by no means conspicuous, although probably the
tarsus (especially the metatarsus or first joint) is proportionately
longer. Even Dolichopeza, with its excessively long and delicate
legs, is paralleled in the Lrmnogprin& by such genera as Mongoma;
whilst in one section of the present subfamily (CTHNOPHORINI),
the legs are comparatively the shortest and stoutest in the family.
The position of the wings in repose is not a good distinctive
character, though it has been put forward. TIPULIN# are com-
monly supposed to rest usually with their wings divaricate (or
236) ~ TIPULID®.
spread out flat), and Z%pula itself generally does so; yet it has
been observed that in the group containing those species with
marmorated wings (as in the himalayensis group among Oriental
and the vernalis group among European species) the wings are
more often folded when resting. Moreover Pachyrhina, the second
largest genus in the subfamily, forms an important exception.
The value of the habit as a subfamily character is further dis-
counted by the fact that some LimNnosirn# assume the spreading
attitude of the wings when in repose.
Much difficulty is experienced when an attempt is made to
define the DonicHoPEzINI, CTENOPHORINI, and TIPULINI satis-
factorily one from the other, these groups, though essentially
forming one subfamily, being separated amongst themselves by
characters ‘‘ perceptible to the entomological sense only,” as
Osten Sacken said.
The extreme length and delicate nature of the legs (and, in
a somewhat less pronounced degree, the body also) in Dolichopeza
and its allies is practically the chief .difference between these
genera and both the Ctenophora and Tipula groups. The absence
of the anterior branch of the 2nd vein and the double forking of
the anterior branch cf the 4th vein will suffice to determine
Dolichopeza itself, but in one or two other genera of DoLICHOPEZINI
the former is present, being perpendicular and not oblique, and
this feature makes the rhomboidal cell more or less square.
Between the CrmnopHoriNt and the T1puLrnt several stronger
differences exist, although it must be remembered that there are
a number of exotic genera which, in the matter of antenne,
bridge the apparent gap between the conspicuously pectinate form
prevalent in male Ctenophora and the normal antenna of 7%pula.
The following table, therefore, must be accepted with the
intimation of the existence of various intermediate and anomalous
forms, although none such are actually present in the Indian
fauna.
‘able of Sections of the TIPULIN E.
Legs not of excessive length and slenderness, either
comparatively short and stout or normally long
and slender; the 2nd longitudinal vein forked,
the anterior branch short and oblique.
Body stouter; neck absent; nasus reduced to
an obtuse hairy projection; antennze nor-
mally pectinate or subpectinate in the male,
never verticillate ; legs distinctly shorter and
stouter; abdomen generally broader, often
widened just before or at the tip; genitalia
large aud complex. Body colours nearly
always vivid and.well marked .......... CrpNoPHORINI.
Body comparatively slender, elongate, normally
tipulidiform ; neck almost always present ;
nasus always present, elongate, narrow ;

antennze normally not pectinate,* the flagellar
joints always verticillate ; legs normally long
and slender; abdomen elongate, cylindrical,
seldom widened. towards or at the tip, unless
due to the genitalia, which are generally
large and complex in 7%pula, less so in some
other genera. Body colours mainly brownish
and yellowish ; brighter in Pachyrhina .... Trevutnt.
Legs of excessive length and slenderness, more so
than in the normal Tipulid forms ; the 2nd longi-
tudinal vein normally not forked {Dolichopeza),
if so, the anterior branch either obsolete or perpen-
dicular, thus making the rhomboid cell more or
less square ; nasus normally absent t .......--. DoLicHOPEZINI.
It must be remembered that probably not one of the characters
herein employed is absolutely consistent throughout any particular
section, the nearest approach to stability perhaps being the verti-
cillate nature of the flagellum in TrruLint.
Section CTENOPHORINI,
In addition to the genera with typically pectinate antenne in
the males, this section contains several others in which this.
character is less fully developed or even entirely absent. Yet as
the group is represented in the East by practically one genus only
(Pselliophora), there is no need to enumerate the peculiarities of
the exotic forms. Apart from Pselliophora, a species of Prionota
has been described by Van der Wulp from Java (P. nigriceps).
All the species described by the older authors correctly belonging
to Pselliophora were placed in Ctenophora, but they have now all
been satisfactorily referred to the former genus with one exception,
C. xanthomelana, Walk., of which only the female was originally
described, and the species not having been seen since, it is im-
possible to decide where it should be placed, the probability being
that it too is really a Pselliophora. It comes from “ East India.”
As descriptive of the section, little can be added to the char-
acters given in the table above, so far as the Oriental genera are
concerned. The pectinate antenne in the males, the shorter,
stouter legs, the usually bright and sharply defined colours that
distinguish most of the species, make them easily recognisable.
* Exceptions occur, but not in Eastern genera ; one, for example, Ozodicera,
comes from South America, which is practically a Z%pu/a with pectinate male
antenne.
+ Absent in Dolichopeza, but present in Scamboneura and Megistocera, both
Oriental genera.
Prionota may be described briefly as having the appearance of a Pachyrhina
or Tipula, the venation of a Ctenophora, and antenne markedly serrate on the
lower side in both sexes, owing to the emargination of the base of each joint of
the flagellum except the last one. P. nigriceps, Wulp, the only known species,
has an orange-yellow thorax, an abdomen yellowish on the basal half, blackish
on the apical half, with the legs yellowish, blackish at the joints. It is 16 mm.
in length.

GENOTYPE, Tipula atrata, L.
Head transverse, with somewhat prominent rounded bare eyes.
Epistome enlarged, snout-like towards the tip. Proboscis rather
prominent, with rounded hairy labella. Palpi four-jointed, long,
the last joint the longest, whiplash-like. rons in both sexes
broad ; ocelli absent. Antenne long, prominent, 13-jointed ;
the flagellar joints in the male cylindrical, with two, three, or four
comb-like branches ; in the female rounded, or saw-like on the
underside. Zhorax very arched, neck moderately distinct ; the
transverse suture moderately deep and distinct, a little emarginate
posteriorly. Scutellum small, metanotum well developed. Abdo-
men elongate, eight-segmented, clubbed at the tip in the male,
widened towards, but not at, the tip in the female. Genitalia of
male large and complex, their structure varying with the species ;
sometimes with a conspicuous organ on the belly in addition.
Ovipositor in female broad, sword-like, prominent, horny. Legs
moderately long and stout, but about the shortest of any in the
family TrpuLIp#; tibize with strong spurs at the tip; metatarsus
lengthened, claws distinct. Wings comparatively large, of moderate
width, the anal angle somewhat squared. One marginal, two
submarginal, and five posterior cells. Auxiliary vein more than
half the length of the wing, turning into the Ist longitudinal vein
at its tip; the Ist longitudinal vein turning at its tip into the
short anterior branch of the 2nd vein, which is practically always
oblique or nearly perpendicular ; a short cross-vein (costal cross-
vein) unites the 1st vein, shortly before its tip, to the costal vein,
thus forming the rhomboidal cell characteristic of the TreuLIN 2 ;
the 2nd longitudinal vein emerges about the middle of the wing,
generally bisinuate; the 3rd generally before the middle of the
2nd, gently curved ; the anterior cross-vein is comparatively short,
the discal cell pentagonal, the 2nd posterior cell petiolate, the
petiole moderately long, the posterior branch of the 4th longi-
tudinal vein forking at about the middle of the discal cell, the
posterior cross-vein placed at the fork; the 5th, 6th, and 7th
veins normal, the latter rather short.
Life-history. The metamorphoses of several European species of
this genus are known, being described by Fischer, Bouché, and
others.* The larve live in decaying wood, but in view of the
probability of the genus not being Oriental, they are not described
here.
* Brauer has described the life-history of C. bimaculata, Kaltenbach ; also
Perris that of C. atrata (in decaying willows). Schiner mentions a second
generation, born in captivity, of the former species.
CTENOPHORA. 289
All the Oriental species of the older authors, described originally
under Ctenophora, are now referred to Pselliophora, and it is
highly probable that the present genus does not exist in the
Oriental region at all, being confined exclusively to Europe,
Siberia and North America, with the exception of a single species
from Persia.*
There is, however, one species, C. wanthomelana, Walk., from
“« Hast India,” of which it is impossible to decide the correct
generic position, the male being still unknown; in fact, the
original type female (which still exists in good condition in the
British Museum) appears to be the only example in existence.
Ctenophora melanura, Walk. (List Dipt. Brit. Mus. i, p. 78) is
not even a Tipulid at all, but a large species of Sargus, as stated
by Osten Sacken after examining the type at the British
Museum.

(1848).
““ Nigra, thorace ferrugineo rufo trivittato, abdomine basi fulvo,

‘“* Head and appendages black ; feeiers serrulate, much less than
half the length of the chest; chest ferruginous, with three very
broad brownish red stripes, varied with reddish brown on each
side and behind; abdomen black, attenuated towards the tip, and
reaching much beyond the length of the wings; segments from
the first to the third, orange-tawny ; legs black, pubescent ; wings
brown, with a small dark brown brand near the tip of the fore
border ; veins dark brown ; poisers tawny with brown tips.
‘Length of the body 14 lines; of the wings 22 lines.
‘“‘ Kast India. From Mr. Children’s collection.” ( Walker.)
The male of this species still being unknown, it is impossible to
say whether it is a true Clenophora or not. In all probability it
will eventually prove to be a Pselliophora, a genus confined to the
Eastern tropics, with the exception of a single species (P. fum-
plena, Walk.) from China.t Until, however, the point is decided,
both the genus Ctenophora and the species wanthomelana must
presumably figure in Oriental lists.
* Persia is, however, as much Palzarctic as Oriental. It is true that there
is yet one species of which the locality is still unknown—C. constans, Walk.
(Dipt. Saund. p. 448, 2), but this hardly affects the argument.
+ Unless this species comes from South China (the original reference gives
merely ‘‘China’’), I should have doubted its being a Psel/iophora but for Osten
Sacken’s examination of the type at the British Museum, where are also some
other specimens from China which appeared to that author to represent a
variety of the same species.

Genus PSELLIOPHORA, Os. Sac.
Pselliophora, Osten Sacken, Berlin. Entom. Zeits. xxx, p. 165 (1886).
Guyoryes, Vipula leta, F.; by present designation.*
Osten Sacken’s differentiation of this genus from Ctenophora is
as follows :—
“ Pselliophora (which means bracelet-bearer), gen. nov., comes
nearest to Otenophora, sensu stricto, represented by the European
species pectinicornis, flaveolata, elegans, ete. It is easily distin-
guished, however, by the following characters :—
(1) The four branches issuing from the same antennal joint
(in the male) are of the same length (in Ctenophora, s. str., the
inner pair is distinctly shorter); (2) the branches of the male
antenne are clothed with rather long, soft, not very dense hairs ;
(3) the 12th joint has two pairs of branches (only one in Ctenophora,
s. str.); (4) the forceps of the male has a different structure ;
the long protruding adminiculum, so conspicuous in Ctenophora,
s. str., is wanting here; (5) the females are more difficult to dis-
tinguish from those of Ctenophora, s. str., the most trustworthy
character, as far as I can see, lies in the structure of the 3rd joint
of the antenne (1st joint of the flagellum), which here becomes
broader from base to tip, without having the expansion on the
underside, such as exists in the females of Ctenophora, s. str. ;
the other joints are more rounded, and thus the flagellum appears
less serrate on the underside; the latter half of the abdomen is
much less expanded here, the upper valves of the ovipositor more
straight and pointed. .
“Most of the species of this group have a white ring at the
base of each tibia (hence the name of the group); the wings are
often brown, with well-defined white or yellowish spots ; sometimes
uniformly brown, or yellowish with brown tips. The two pairs
of branches on joints 4-12 of the male antenna are slender and
rather long, from one and a half to two and a half [times] the
length of the joints; the longest are in the middle of the flagellum.”
The present genus is identical with Ctenophora except for the
few differences mentioned above.
Those new species of which only the females are known are
placed here only temporarily, as until their males are discovered
it is impossible to define their generic position with certainty.
Life-history. The metamorphoses of no Oriental species have
been studied, but the larve probably live in decaying wood, as is
the case in the allied genus Ctenophora.

3 2. Head bright orange; proboscis and palpi orange or
orange-yellow with a little concolorous pubescence. Antenne
of male with thirteen joints, of female eleven; in both sexes the
1st scapal joint is very large, approximately oblong, slightly curved
upwards, orange, sometimes with black streaks on the upper-
side and sometimes wholly reddish brown or brownish orange,
the 2nd scapal joint very sinall, easily overlooked, especially in the
male in which it is orange, whereas in the female it is always black.
In the male the Ist flagellar joint has a blunt projection on the
lower side, making the whole joint Y-shaped, black, with a pale
yellowish white tip; it is unbranched. The remaining joints in
the male are cylindrical, elongate, the basal two-thirds black or
blackish brown, the apical third pale yellowish ; each joint bears
two pairs of slender finger-like blackish brown branches which
droop downwards; the first pair is situated at the base of the
joint, the second at the distal end of the black portion; the
last joint is simple and much elongated. All the branches, and
in fact the whole antenne, are shortly pubescent. In the female
the flagellum is distinetly only of nine joints, the 1st longer than
the rest, broader at the tip, the 2nd rather similar though not so
long, the rest subannular, the apical joint conical. The whole
flagellum black, with short black pubescence. Zhorawv wholly
bright orange, a little yellow just below the dorsum and sometimes
on the scutellum and metanotum. Abdomen very variable ; bright
orange, with the bases of the segments more or less black ;
sometimes the greater portion of the dorsal surface blackish,
sometimes hardly any black colour present. Genitalia of male
orange, with blackish marks, these varying also; in the female
shining black, often the last two or three segments black also.
Legs: coxee and femora bright orange, tips of latter broadly
black; tibie and tarsi black or blackish, a moderately wide,
distinctly pale yellow or yellowish white band on the former at or

ossible to mistake one for the other if the descriptions of each are consulted.

immediately beyond the base. Legs microscopically pubescent.
Wings rather deep brown or blackish brown. Two large, very
conspicuous oval orange-yellow spots, beginning on the costa and
extending nearly to the hind margin, the distal side of the first
spot being just beyond the middle of the wing; the second spot
begins a little before the proximal side of the discal cell and
encloses the posterior cross-vein, its distal costal limit being at
the tip of the 1st longitudinal vein; between these two large
spots a smaller one, round or oval, near but not touching the costa,
enclosing the base of the 2nd longitudinal vein. The base of the
wing is also orange-yellow, in some cases the colour wholly united
with the nearer large spot, but always joined to it on the costa.
In one example the small round spot is also united to the proximal
one of the large spots. In some specimens the small spot is
much reduced, possibly occasionally absent. Halteres orange.
Length 8 10-12, 2 15 millim.
Redescribed from several specimens of both sexes in the
Indian Museum and my own collection from Dehra Dun (foot of
Mussoori Hills); Kanara, Bombay, vii. 07; Bangalore, 3000 ft.,
11-15. x.10 (Annandale); Trivandrum, Travancore State, iv. 89 ;
Caleutta, 13. vii.97. Also in the Vienna Museum and my own col-
lection from Ceylon. Apparently commonly distributed throughout
India, and probably also the East generally. Van der Wulp
records it from Bombay, Sind, and Ceylon.
Type. The location is uncertain, unless it is in the old Fabrician
collection. It is curious that although described in a few words
only, over a hundred years ago, the species is so well marked that
there does not exist a single synonym to it.
‘Van der Wulp quotes ‘ pl. ii. 1’ as a figure of this species in
Wiedemann, but [I find no such figure. In the Pusa collection
are a male and female taken in cop. in the Shevaroys, 4000 ft.,
Madras Presidency, 26. vill.07, on coffee bushes. In the Indian
Museum are two specimens that represent well-marked varieties
of this species, to one of which a name is given. ‘The first speci-
men is from Katihar, Purnea District, N. Bengal, and is a female
in good condition taken by Mr. Paiva, 23.11.09. It differs from
the typical form by all the cells on the posterior half of the wing
being pale grey in their centres; one or two centres being almost
entirely clear. The 3rd, 4th, and 5th abdominal segments have
a subquadrate black spot on the dorsum of each.
«The second specimen I term var. trilineata, from the presence
of the usual three tipuliform black thoracic stripes, the median
one extending over the anterior margin on each side as far as the
front coxee. The outer stripes are replaced behind the suture by
a large spot on each side. There is a blackish mark on the pleura
below the wing, and the hinder side of the metanotum is shining
black. The wings have the clear spaces as in the preceding
variety, though not quite so obvious, and the last two or three
abdominal segments are blackish, some distinct darkening of the pre-
ceding segments being noticeable. The yellow colour of the legs is
PSELLIOPHORA, 293
deep chrome, not orange. It was taken by Mr. H. L. Andrewes,
September 1910, in the Nilgiri Hills (3500 ft.).
“The yellow marks on the wing in both forms are so exactly
like those in the typical form that they cannot be regarded but as
varieties.” (Brunetti, l.¢., p. 241).

3 Q. Head yellow, often lemon-yellow, a dark brown spot or
pair of spots on back of occiput, a small elongate mark over base
of each antenna or at its side. Proboscis yellow or brownish
yellow, often with a brown streak on each side above, brown
below; palpi with Ist joint brown, the remainder yellow, wholly
pubescent. Antenne much as in P. leta, except that the scape
is more black (probably sometimes wholly so). The whole
antenna in female black, shaped mainly as in leta, but the joints
more flattened, not at all annular. Thorax yellow, sometimes
tinged with a little orange, sometimes lemon-yellow. Three
dorsal brown stripes of the usual pattern in Trrunmp®, the
median one beginning on the anterior margin, generally narrowly
divided in the middle; the outer ones consist of an oval spot in
front of the suture, joined to one, sometimes two, contiguous
spots behind the suture; the three (or two) form a stripe from
well behind the shoulder to the posterior margin of the dorsum ;
a brown streak at base of collare, carried on each side right down
at the sides and continued on to the fore ccxe. Scutellum and
metanotum concolorous with thoracic dorsum; a brown spot on
each side of the scutellum, like a continuation of the outer
thoracic dorsal stripes. The metanotum with a brown mark
(sometimes divided) on hinder side. Sternopleurew with a broad
dark brown horizontal stripe on upper part and another on lower
part, sometimes indistinct (possibly occasionally absent); a brown
mark here and there on the rest of the pleure. Abdomen yellow
or orange-yellow ; bases of segments more or less dark brown or
blackish, the extent of the colour variable, and apparently more
extensive in the female. The basal segment generally wholly
yellow, the apical one or two segments generally black. Genitalia
of male shining brownish yellow, with blackish marks and
pubescence. Ovipositor of female shining black. Legs: cox
yellow or brownish yellow, often with dark brown streaks ;
femora dirty brownish yellow; tibiz and tarsi similarly coloured
but darker, the former with a moderately narrow whitish ring at
base. Wings moderately deep brown, with yellow marks that
are variable, usually four in number and of considerable size.
Normally, two rather large round or oblong spots just below the
costa, the first placed clear of the base of the wing, its distal side

at one-third of the wing’s length; the second large spot touches
the tip of the 1st longitudinal vein, enclosing the anterior cross-
vein and the discal cell and posterior cross-vein. Between these
two larger spots a smaller round one over the base of the 2nd
longitudinal vein, as in P. lta, and a similar round spot on hind
margin of wing over tip of 6th longitudinal vein. Very small
spots and streaks are liable to occur in various parts of the wing,
especially at the extreme tip, the tips of the 4th and 5th veins,
and so on. Sometimes a yellow spot near, but not at, the base of
the wing, and connected with the proximal large spot on the
costa. Halteres relatively small, brownish yellow.
Length 3 9-14, 9 14-15 millim.
Redeseribed from several examples of both sexes in the Indian
Museum and my own collection, all from Ceylon, where it appears
to be a common species especially in May, June and July, small
parties of them being seen flying together over the roadways and
under branches of trees. The Indian Museum dates range from
29. y. to 18. ix., but it probably occurs in Ceylon all through the
summer. Mr. Gravely has taken it at Peradeniya “at light.”
Type (a female) in the British Museum, from Ceylon.
The male is much less common than the female and I believe
has not been described, but it is present in the Indian Museum
and shows no peculiarities beyond the ordinary sexual differences.

2. Head bright shining orange-yellow, with scattered hairs ;
a frontal spot, almost bisected in the middle (just above the
antenne), shining light yellow-brown, extending from eye to
eye. Eyes small, black, and placed well forward so that the
back of the head is very wide, and joins the equally broad vertex
which is orange-yellow. Face rather considerably covered with
long yellow hairs. Antenne concolorous, covered with microscopical
silver-grey dust: the Ist joint long, cylindrical, 2nd short, bead-
like, 3rd and rest cylindrical; 3rd as long as Ist, remainder
gradually shortening, the last three very short and close together,
the 13th style-like. Palpi orange-yellow, tip black. Thoraw
concolorous, with irregularly scattered hairs, shining, bare. The
prothorax reduced to a small circular thick disc, bright yellow ;
humeri brown. Mesothorax with three wide, shining, light brown
stripes, tapering behind, the Ist central and attaining the anterior
margin, the stripe on each side reaching the shoulders and
terminating above the mesopleure. Behind the middle transverse
suture the dorsum widens out until the posterior corners form
sharp angles. This posterior portion bears a wide brown stripe
on each side, divided by a small longitudinal suture; the stripes
beginning behind the ends of the two dorsal side stripes which
are in front, and extending backwards to the small scutellum.

which is all yellow. Metanotum of moderate size, yellow. Sides
of thorax yellow, with a shining, very dark brown triangle just
below the root of the wing, and a downward brown streak
behind and rather above it. Underside of thorax dark brown; a
prominent, small, circular, pale yellow callosity in front of the
hind eoxe, Abdomen concolorous, with irregularly scattered hairs.
Bases of all the segments brown, the part so coloured apparently
varying in breadth; 2nd segment much contracted ; 3rd and 4th
suddenly widened; the rest together tapering to a point. Ovi-
positor short, reddish brown, shining. Belly yellowish, with traces
of some transverse bands, corresponding to those on the upperside.

wholly bright orange; a very faint indication of three darker
stripes. Abdomen bright orange, with short concolorous pub-
escence ; posterior margins of segments a little deeper orange,
and small blackish marks (apparently the ground-colour of the
abdomen shewing through the tomentum) here and there at the
sides. Belly similar. Last segment and ovipositor shining black,
tip of valves reddish. Legs: coxe and femora bright orange, tips
of latter narrowly blackish brown, remainder of legs dark blackish
brown. Hind tibie only with a narrow pale yellowish ring
immediately beyond the base. Wings orange-yellow ; the apical
part as far inwards as the whole of the outer marginal, sub-
marginal and lst and 2nd _ posterior cells, brown ; the colour
absolutely demarcated proximally by the veins delimiting these
cells, but extending, more indistinctly, into the discal cell and
posteriorly, also indistinctly, into the 8rd and 4th posterior ceils.
Halteres orange.

24. Head brownish yellow, vertex a little tinged with grey.
Palpi blackish. Antenne very conspicuous: scape brownish
yellow, 1st joint a little over twice the length of the 2nd; flagellar
joints very deeply serrate on underside in the shape of two
pendent lobes to each joint, of equal size and length, the proximal
one black, the distal one brownish yellow; the last flagellar joint
(11th) has a conical tip, with a small distinct apical style; each
joint bears a verticel of hairs (four in number) at its base.
Thorax brownish yellow, more yellowish anteriorly, with three
darker dorsal stripes; the median one rather broad, and bisected
by a narrow dark brown line, with which all the stripes are rather
sharply delineated. Two spots behind the suture of similar colour
and delineation, of normal shape, the anterior one approximately
rounded, the hinder one more oblongo-triangular, Pleure a little
greyish. Abdomen brownish yellow; the segments with blackish
markings on the kind margins towards the sides (the apical balf
of the abdomen is wanting). Leys: coxe and femora brownish
yellow; tibise and tarsi dark brown or blackish. Wings pale grey,
base and costal cell yellowish; stigma dark brown but ill defined,
and a brownish sutfusion, irregular in extent, below the stigma
extending around the discal cell; also in less distinct manner, at
the base of both basal cells, at the origin of the 2nd longitudinal
vein and over the posterior cross-vein, and here and there over
some of the veins. Halteres brownish yellow.
Length 12 millim. (incomplete).
Described from a single example in excellent condition (except
for the loss of the apical half of the abdomen), taken by Felder
in 1861, in Ceylon.
Type in the Vienna Museum.
The end of the abdomen being broken off, the sex of the
specimen is undeterminable. The species is a very conspicuous
one and, as regards the antenne, quite unlike any other that I have
seen or read of. The abdomen, so far as the middle, shows
no trace of any increase in width. It may not be a Pselliophora,
but the antenne cannot by any stretch of imagination be asso-
ciated with Tipula, yet the flagellum is distinctly verticillate, an
essentially Tipuline character.
TIPULA. 297
Section Z7PULINI,
Although, as has been mentioned, several abnormally con-
structed forms belong to this section, approximating in some
degree to the CrmnoPHoRINI, none of these have as yet occurred
in the Orient. Zipula and Pachyrhina alone represent this group
in the East, these, moreover, being the two most representative
genera of the section. Little can be added to the characters
already given in the preceding table of sections.
The colours in Tipula are comparatively sombre, consisting
mainly of various shades of browns, yellows and dull blacks,
whilst in Pachyrhina the species are generally bright yellow with
black, well-defined markings.
Some European species are mainly black, with yellow markings,,
one or two of this nature having been described from the East,
but not from India.

Head more or less oval. Proboscis moderately long, com-
paratively broad, the upper part prolonged narrowly in the form
of a nasus or nose, the lower part bearing well-developed hairy
labella at the tip; palpi four-jointed, long, cylindrical, the last
joint whiplash-like, as long as the preceding three joints taken
together. Eyes separated by a frons of one-third to one-fourth
the width of the head in both sexes, rarely a little wider in the
female. Vertex slightly, sometimes considerably arched. Antenne
of thirteen joints, long, generally a little longer in the male than
in the female; 1st scapal joint elongate, cylindrical, 2nd very
short, not wider than the Ist scapal or Ist flagellar joint
flagellar joints cylindrical, often slightly enlarged at their
bases, sometimes very slightly contracted just before their tips ;
1st jomt always considerably longer than the others; each
flagellar joint bearing four verticillate hairs, the two on the upper-
side long and divaricate, those on the underside much shorter ;
scapal joints never verticillate, but bearing some short bristly
hairs at the tip of each joint, often a long hair or two in addition.
Thorax arched, practically bare, more or less elongate in front,
produced into a short conical neck. Transverse suture distinct.
Scutellum moderate in size, semicircular; metanotum highly
developed. Abdomen, irrespective of the genital organs (which
form the 9th), of eight segments; cylindrical in the male or
more or less incrassated at the tip, or entirely linear throughout

its length if the genitalia are small. In the female, rather more
flattened, generally a little broader, especially towards, but not
actually at, the tip. Genitalia of male nearly always large and
complex, of varied structure according to the species, consisting
usually of a moderate-sized dorsal plate, a large curved or V-shaped
ventral plate, and more or less developed side plates (often in-
visible, possibly absent); a pair of stoutly built conspicuous, two-
jointed claspers, the second joint taking the most varied forms ;
and inner organs of varying form according to the species, with a
long filamentous penis, generally concealed. In the female the
genital organs reduced to the normal pointed pair of horny
valves, the lower pair much shorter, set much further back at
the base and sometimes twisted round a little towards the side.
Legs very long and slender, especially the tarsi, which are generally
longer than the tibie ; tibize with small spurs at the tip; claws
and pulvilli small. Wings elongate, of moderate width; tip
narrowed, sometimes almost pointed; anal angle generally but
not always narrowed. One marginal, two submarginal, and five
posterior cells. Auxiliary vein ending always some distance
beyond the middle of the wing; the Ist longitudinal a little
longer, turning into the 2nd at its tip, the auxiliary turning
down into the Ist; costal cross-vein often placed at such an
angle as to make it appear like the continuation and end of the
Ist vein; the 2nd vein emerges in a gentle curve, sometimes some
little way before the middle of the wing, sometimes distinctly
beyond it, the anterior branch always oblique; the 3rd vein issues
shortly before the middle of the 2nd vein, the distance between
its origin and the forking of the 2nd vein differing according to
the species. Sometimes there is no obvious basal section to the
3rd vein; sometimes it is longer than the nearly upright anterior
cross-vein, with which it is usually ina line. Discal cell invariably
present, pentagonal, of moderate size; the 2nd posterior cell
always petiolate, the petiole varying in length with the species
but by no means constant in the same species. The posterior
eross-vein very oblique, nearly always at the fork of the lower
branch of the 4th vein, which forking occurs somewhere on the
hinder side of the discal cell ; occasionally the cross-vein occurs a
little before the furcation, in which case it allows of the ultimate
(5th) posterior cell coming into contact with the discal cell ;
except in these latter cases the contact of the 5th posterior cell
with the discal is only punctiform. The 5th longitudinal vein
nearly straight or angled at the junction with the posterior cross-
vein; 6th vein nearly straight, lying comparatively close to the
5th; 7th rather short, nearly or quite straight.
Range. World-wide.
A character greatly helping to distinguish this genus from
Pachyrhina is the fureation of the lower branch of the 4th
longitudinal vein. This occurs beyond the base of the discal cell,
the posterior cross-vein being situated at the fork. Thus, of the

Wings with one submarginal cell, four or five posterior cells, and

the 2nd vein, meeting it, instead of ending in the costa.t The
auxiliary vein ends abruptly, without turning into either the costa
or the 1st longitudinal vein. The marginal cross-vein, as such, is
absent, but there is present a supernumerary cross-vein joining
the costa to nearly the tip of the 1st longitudinal vein. =
This section is intermediate between the subfamilies TrpuLIN”®
and LimNosBirn.&, but is considerably more akin to the latter. Its
affinities with the Liwnosirn® are as follows :—
(1) In the palpi, which, although elongate, have not the whip-
lash nature of these organs in the TIPULIN#.
(2) In the absence of the peculiar fold in the wings, which in
most of the TrpuLmIn® runs more or less across the wing trans-
versely, beginning in the region of the stigma, and which I have
termed the obliterative streak.
(3) In the length of the inner marginal cell—that is to say,
that portion of the marginal cell enclosed by the turned-down
1st longitudinal vein, which in most T1pULIN® is much shorter. §
* Some European authors (Zetterstedt, Walker, etc.) speak of the antennz
as 17-jointed, which is incorrect ; the error is due to the fact that in dried
specimens the prolongation of the 16th joint looks like an additional one.
+ There is at least one exception to this form of venation (Phalacrocera
veplicata, L., of Europe), and others may occur.
t This cross-vein I have proposed to call the costal cross-vein.
§ This is according to Osten Sacken; but I have not found if so myself,
there being, judging from my own experience only, no difference between the
two groups in this respect.
CYLINDROTOMA, 359
(4) In the number of the antennal joints—16, which is the
usual number in the Limnopirtn.#, whereas in the Tiputinm the
normal number is 18.
(5) In the number of posterior cells—four normally, but occa-
sionally five. This, however, is not so much a resemblance to the
Limnostin#, where genera with five posterior cells are by no means
rare, as a difference from the T1puLin #, in which the usual number
of cells is five.
There appears to be no direct affinity to the Trrutina, except
the general appearance, which is much more like that of a small
species of T%pula than of a Limnobiid. Another possible point of
resemblance is that the Cynrnproromint, though having only one
submarginal cell, have spurs to the tips of the tibiae, whereas all
those genera of Limnog1in & that possess only one submarginal cell
have no spurs to the tibie; but this, teo, is rather a difference
from the Limnosirn& than any actual affinity to the Trpunin a».
The abrupt ending of the auxiliary vein is in itself a character
of an intermediate nature, as in the T1putIn® the vein nearly
always turns downwards into the 2nd vein, whilst in the
LIMNOBIIN® it generally turns upwards into the costa.
“The CyLinproromina, with all the prevailing characters of
the Tipurip® Brevipaurr, show important aberrations in the
course of the veins in the vicinity of the stigma—aberrations
which prove a leaning towards the T1putipm Lonerpatrr. The
latent affinity to the latter is further proved by the presence of
spurs on the tibie and by the general appearance.” (Osten
Sacken.)
The few genera making up this section are so closely interwoven
that there is some difficulty in separating them, and from the
point of view of some entomologists a separate genus might be
established for nearly every species, owing to the range of variation
shown in the antenne, the venation, the genital organs of the
inale, and other characters.
At present, however, only the genus Cylindrotoma itself has
been found in the East, with but a single species to represent it.

structure.* Legs slender, tibie with distinct spurs at the tips;
fore cox short ; empodia distinct. Wings with one submarginal
cell, five (normally) posterior cells, + and the discal cell closed.
The auxiliary vein ends abruptly neither in the costa nor in the
1st longitudinal vein, but sometimes it is indistinctly connected
near its tip with the latter. The Ist longitudinal vein turns down
at its tip into the 2nd ; a more or less indistinct cross-vein connects
it with the costa. The 2nd vein begins about the middle of the
wing, the prefurea forming about half its length ; the Ist longi-
tudinal vein meets the 2nd soon after the origin of the 3rd vein,
which commences just before the middle of the 2nd vein, forming
with the 2nd vein a fork, the submarginal cell thus being
triangular. Anterior cross-vein at origin of 3rd vein, uniting
with the discal cell at one-third the length of the latter; discal
cell closed, more or less oblong; anterior branch of 4th vein
forked soon after quitting discal cell, the veinlets more or less
parallel ;{ posterior cross-vein just beyond discal cell; 7th vein
comparatively short.
Range. The tew species known are distributed through Europe,
North America (including Alaska), and South America, in addition
to India.
Life-history. The metamorphoses of a moderately common
European species, Cylindrotoma distinctissima, Mg., have been
observed by more than one biologist. The larva has the ex-
ceptional character of living on the undersides of the leaves
of low-growing plants, like the caterpillar of a Lepidopterous
insect. It is green, elongate, flattened, linear, only a little
pointed at each end, with a longitudinal crest along its back,
consisting of a row of fleshy processes pointing backwards ; the
lateral margin is broad, with many excisions, formed by fleshy
points. The larva, before transforming, quits its food-plant and
attaches itself to a stalk of grass, on which to undergo the pupa
state. The pupa bears some resemblance to that of a Lepi-
dopterous insect, the thorax bearing several horny processes.

* Osten Sacken says:—‘‘The long narrow linear horny lamella, which
usually protrudes when the living insect opens its forceps, ends in three sharp
points.” Speaking of the ovipositor of the female, he continues:—‘ It is
rather large, the upper valves are lamelliform towards the tip, and the lower
ones are curved in such a manner as to leave a considerable empty space
between them and the upper ones.”
+ If my new species is correctly placed here, the generic description must
read, ‘‘four or five posterior cells.”
t Schiner, in describing Cylindrotoma distinctissima, Mg., the commonest of
the European species, infers that the forking of the anterior branch of the 4th
vein is not always constant, so that specimens of this species nay have four or
five posterior cells accordingly. In Needham’s figure of the wing of this
species he shows the auxiliary vein very distinctly turning up into the costa,
with an equally distinct subcostal cross-vein near its tip, uniting it to
the Ist longitudinal vein near the tip of the latter. This is a mistaken
interpretation.
CYLINDROTOMA. 861
The larva, according to Schiner, feeds on Stellaria nemorwm,
Anemone nemorosa, and Alliwm wrsinum. It is also found on
Viola. Zeller (‘Isis, 1842, p. 808) gives a good description
of the larva; whilst Schellenburg, who figures it (‘Genres des
Mouches’), may also be consulted on the same subject, although
this author mistook the larva for that of a Pachyrhina.
The larva of a Eurepean species of another genus (Phalacrocera
veplicata, L.) lives upon aquatic plants growing beneath the surface
ot the water. It is very hardy, as it has been known whilst in
captivity to pass the winter in this state even though ice formed
on the top of the water. In May it pupates and floats or
descends below the surface at will by means of several pairs
of hooks by which it traverses the stems of plants. De Geer
(‘Insectes,’ vi, p. 351, pl. xx) may be consulted on the subject.

¢. Head, viewed from above, oval ; blackish, bare above; frons
short, much wider on vertex, where it is about one-fourth the
width of the head. Face below antenne a little lighter ; palpi
small, black. Scapal joints of antenne short, yellowish; the
fourteen joints of the flagellum dark brown, very elongate,
somewhat difficult to distinguish from one another, especially
towards the tip, each joint being covered with very long thin
verticillate hairs, quite irregularly arranged. The antenna is
as long as the whole body. Thorax reddish brown, closely
punctured round the edge of the dorsum, a little in front of
and between the three dorsal, almost concolorous stripes, the
configuration of which is distinct, although they show only a
slightly darker shade of colour ; a narrow band, a little lighter a
colour, just below the dorsum, is free of punctures, but the sides
of the thorax, below this band, the scutellum, and the metanotum
are all closely and conspicuously punctured. Abdomen linear,
narrow, dark red-brown, a little blackish here and there, prac-
tically bare; belly similar. Genitalia blackish, rather small ;
a pair of slightly pubescent two-jointed claspers, with some
internal organs, protected by an upper and lower plate. Legs:
coxe brownish yellow, bare; remainder of legs similarly coloured,
gradually becoming darker towards the tips, the tarsi being
blackish. Wings grey. Auxiliary vein apparently turning down-
wards into the Ist longitudinal vein at some little distance beyond
the middle of the wing, and connected, just before its tip, by a
short cross-vein with the costa. The Ist vein turns distinctly into
the 2nd a little beyond the level of the anterior cross-vein, and
a little way before its tip it is connected with the costa by a
cross-vein, presumably the marginal cross-vein. The 2nd longi-
tudinal, which begins some distance before the middle of the wing,
gently arcuating, turns abruptly up (at the point where it meets
362 TIPULID &.
the anterior cross-vein, at a similar angle to that taken by the
4th vein in Musca and Lucilia) until it meets the 1st vein ; thence
running parallel to the costa and ending in it some little distance
before the tip of the wing. The 83rd vein, which runs nearly
straight to the exact tip of the wing, and the anterior cross-vein,
originate together from the angle in the 2nd vein where the latter
marks the end of the prefurca, this section being longer than the
rest of the 2nd vein. Discal cell hexagonal, the lower half con-
sisting of three sides, the cell twice as long as broad and about as
long as the second and third posterior cells; anterior cross-vein
shorter than proximal side of discal cell; posterior cross-vein just
beyond middle of discal cell; 5th vein sharply angled at its juncture
with the posterior cross-vein, whence it runs straight to the wing-
margin; 6th and 7th veins nearly straight. The Ist, 2nd, and
3rd veins near their tips are microscopically spinose.
Length 6-63 millim.

Eyes bare, separated by a comparatively narrow frons. Proboscis
moderately long, elongate in at least one genus (Geranomyia) ;
terminal lamellz linear, narrow. Palpi four-jointed, slender, cylin-
drical. Antenne of 14 joints (sometimes apparently 15); scapal
joints of the usual type in Limnopiin®; flagellum of oval or cylin-
drical joints, more or less pectinate in Rhypidia. Genitalia of male
consisting generally of a pair of two-jointed claspers, the Ist joint
short, cylindrical or conical, the 2nd smaller, sometimes very much
80, bearing, or consisting of, a horny hook, a bifid claw, or similar
appendage. In the female the upper pair of valves may be shorter
than the lower ones (Dicranomyia) or subequal in length; normal.
Legs more or less slender, stouter in Limnobia, long ; tibiz without
spurs at the tip; empodia indistinct or absent, ungues with teeth
on the underside.* Wings moderately broad, sometimes elongate,
with only one submarginal cell, four posterior cells, and the discal
cell closed or open. Auxiliary vein ending about "the middle or
before two-thirds of the wing’s length; subcostal cross-vein near
its tip; submarginal cell longer than 1st posterior cell. The 2nd
longitudinal vein usually begins a little before the end of the
auxiliary vein, the subcostal cross-vein being therefore sometimes
* As I have not studied this character myself, I quote Osten Sacken, who
gave it much attention :—‘“The teeth on the underside of the ungues of the
Limyoprna seem to be peculiar to this section. They must not be confounded
with the more or less square or sharp projections on the underside at the very
basis of the ungues, forming a part of the thickening which always exists there.
The tooth in the LIMNoBINA, even when single, is distinct from this thickening,
and placed before it.” Antocha was the only genus known to Osten Sacken
outside of the Liwnosrini that possesses a form of this tooth.

siderably, enlarged; flagellar joints subglobular, elliptical or short
subeylindrical, pubescent, the longer verticels of hairs differing
considerably in length according to the species, being sometimes
quite inconspicuous. Zhorawv normal, the anterior part prolonged
into a distinct though not conspicuous neck, the side view of the
prothorax triangular or subtriangular. Abdomen normal, of
moderate size,*linear, usually with parallel sides and soft short
pubescence, which is often very inconspicuous or apparently
confined chiefly to the sides and posterior borders of the segments ;
the segments in some species very distinct, in others much less so.
Genitalia of male consisting of a pair of movable fleshy lobes,
oblong, often subreniform, each armed on the inside with a short
curved horny appendage, something like a beak, called by Osten
Sacken a ‘“ rostriform ” appendage, and often bearing on its convex
side one or two stiff bristles. To the upperside of each of the
lobes, another horny appendage, long, slender, attenuated, curved,
is closely applied, and to these organs Osten Sacken gives the
name of “ falciform” appendages, their point of attachment being
the horny, posteriorly pointed, basal plate below. Most of the
different parts of the male organ appear liable to considerable
modification in different species. In the female, the ovipositor
is generally noticeable by its comparatively small size. he upper
valves are short, narrow, arcuate, pointed, the lower ones straight.
Legs generally slender, in some species, especially those of larger
size, less so; usually more slender and often much longer than in
Limnobia ; the pubescence very inconspicuous, often microscopic.
“ Most of the species have a distinct tooth on the underside of
the ungues, near the base, sometimes followed by a smaller one ”
(Osten Sacken). Wings somewhat elongate. Venation, though
typical, showing considerable modifications within certain limits.*
One submarginal and four posterior cells ; discal cell generally
closed. Auxiliary vein ending in costa opposite, or at a little
beyond base of, 2nd longitudinal vein, that is to say, never very
much before or beyond the middle of the wing; in occasional
species it ends a little before the origin of the 2nd vein, and in
quite exceptional cases considerably beyond this point. Subcostal
cross-vein placed in different species at different distances from
the tip of the auxiliary vein, its position, however, being constant
in the same species. The 1st longitudinal vein ends in the costa
near the end of the nearly always present stigma, more or less
beyond the inner end of the submarginal cell, sometimes ending
as far distally as the middle of this cell.t The marginal cross-
vein placed near tip of 1st vein, often more or less in a line with
the upturned end of the latter, but also often quite distinctly
appearing as a true cross-vein, a little anterior to the tip of the

1st vem. The 2nd longitudinal vein begins in the middle of the
wing, either at an eons angle or in a curve of varying sweep,
gently bisinuate; its basal section (that is to say, that portion
from its origin to the emergence of the 3rd vein, or the preefurea)
straight or rather distinctly curved, varying from one-half to
one-fourth the total length of the vein. The 3rd vein with the
basal section of varying length, according to the species, but
tolerably constant in each species ;* its course also varies con-
siderably, sometimes gently bisinuate, in some species forming
nearly a rectangle both at its origin from the 2nd and at its elbow ;
in most species S parallel to the 2nd longitudinal vein or slightly
diverging or pany oroie at the tip. Owing to the 3rd vein
emerging from the 2nd at some distance beyond the base of the
latter, the submarginal cell is always considerably shorter than
the marginal cell, and nearly always longer than the Ist posterior
cell. Anterior cross-vein always situated at the upper basal
corner of the discal cell. Discal cell generally present,? generally
more or less elongate, usually pentagonal, the distal side formed
(as is the general rule in TrpuLip®) of two short veinlets forming
the basal sides of the 2nd and 3rd posterior cells, of which the
3rd is generally a little longer than the 2nd. When the discal
cell is absent, it is generally coalescent with the 2nd posterior
cell. = The 4th vein, when the discal cell is open, has either the
upper or the lower branch forked, in most cases the latter.
Posterior cross-vein placed exactly at or a little before the base
of the discal cell, but its position varies to an appreciable degree
even in the same species. The Sth, 6th, and 7th longitudinal
veins nearly straight, or slightly curved downwards at the tip.
Range. Europe, North America, West and South Africa, the
Orient, and Australasia.
Notes on the venation.—The marginal cross-vein is generally in
a line with the upturned tip of the 1st longitudinal vein, but in
some species (the feature also adventitiously occurring in an
otherwise normal species) it bends a little proximally at its upper
end, thus making it appear as if the Ist vein itself turned down-
wards at its tip into the 2nd vein, whilst being joined by a short
cross-vein to the costa.
There is a figure in Needham’s plates of an American species
(D. immodesta, Os. Sac.) in which the 1st longitudinal is distinctly
shown turning down into the 2nd at its end, no cross-vein being
shown at all. This, it seems to me, may well be an error, as the
* In D. fascipennis, Brun., it is as long as the basal section of the 2nd vein;
in D. ornatipes, Brun., it is rather shorter than the auxiliary vein.
t+ Absent in at least two North American species (D. immodesta, Os. Sac.,

t Osten Sacken mentions a North American species, D. pubipennis, which
normally has the discal cell closed, but out of twenty specimens of it seen
by him, five had it open, and in each case it coalesced with the 37d and not
the 2nd posterior cell.

species is one of Osten Sacken’s own, and he would surely have
mentioned the fact in his monograph, yet he does not do so,
although referring to this particular species on another point.
Needham also illustrates the wing of another somewhat abnormal
species, D. cinerea, Doane. Neither subcostal nor marginal cross-
vein is present; the 2nd vein is comparatively short, turning
upward at its tip; the discal cell is open, coalescing with the
3rd posterior cell, which is pointed proximally, the upper branch
of the 4th longitudinal vein being forked.
A still more abnormal venation is shown by D. whartoni,
Needham, which this author refers doubtfully to Dicranomyia.
The marginal cross-vein divides the marginal cell; the subcostal
cross-vein is absent ; the discal cell is open, coalescing with the
2nd posterior cell, of which latter (posterior) cells there are only
three, through neither branch of the 4th longitudinal vein being
forked; the posterior cross-vein is anterior to the base of the
2nd posterior cell; the 7th vein very short, and the whole wing
more elongate than in any species I have seen.
Affinities of the genus Dicranomyia.—Very close to both Limnobia
and Geranomyia. The latter genus is, of course, quite easily
distinguished at once from both the others by its elongated pro-
boscis, which is immediately conspicuous. Apart from this feature,
however, the three genera have much in common, the present
genus being especially akin to Limnobia,
In the venation the most conspicuous difference is the position
of the tip of the auxiliary vein, which in Dicranomyia ends in
the costa nearly opposite the origin of the 2nd longitudinal vein,
just beyond it or, iu a few cases, a little before it. In a Sew
exceptional cases it is continued some distance beyond the origin
of the 2nd vein; Osten Sacken mentions this regarding four
North American species. In Zimnobia the auxiliary vein nearly
always ends considerably beyond the origin of the 2nd longitudinal
vein, generally about half-way between that point and the tip of
the 1st vein.*
The differences in the male genitalia consist rather of modi-
fications of the same plan of structure than of fundamental
differences of form. The claspers in Dicranomyia are large and
fleshy, whilst in Zimnobia the second joint develops into a strong
horny hook-shaped process.
The relative position of the subcostal cross-vein and the tip of
the auxiliary vein is somewhat different in the majority of species
of both genera, for though the cross-vein is in both sometimes
placed at the tip of the auxiliary vein, in Dicranomyia it is
invariably situated between the 1st vein and the auxiliary vein,
joining them together ; in Limnobia it is very often placed between
the auxiliary vein and the costa, uniting those two veins, in which
* Osten Sacken mentions only one. exception known to him in 1869, the
European D. macrostigma, Schum. I have found it so in one Oriental species,
which I am referring to Limmnobia, i. e., L. festiva.
DICRANOMYIA. 367
case the auxiliary vein ends in the 1st longitudinal and not in the
costa as usual.*
In Dicranomyia the marginal cross-vein is always at the tip of
the Ist longitudinal, and generally in a straight line with it.
In Limnobia it is often some distance before the tip, occurring in
the middle of the stigma or even at its basal end, and when this
occurs it is generally in the less typical species of the genus.
In typical Dicranomyra the marginal cross-vein is close to the tip
of the Ist longitudinal vein.
The discal cell is often open (adventitiously or as a specific
character) in Dicranomyia, but hardly ever so in Limnobia.
A difference between these two genera is also noticeable in the
larval stages, as the larve of Dicranomyia are aquatic or sub-
aquatic, whereas at least some species ot Limnobia are known to
breed in wood and fungi.
Differential characters of minor importance may be found in
the general facies, in Dicranomyia the legs being comparatively
longer and more slender, in Limnobia generally shorter and
stouter ; further, the coloration of the present genus is generally
sombre, grey, blackish, and brownish, whereas in Limnobia there
are numerous brightly coloured yellow and orange species, with
conspicuous black marks, often on the wings as well as on the
bodies. Some species of Dicranomyia have delicately marked
wings.
Life-history. The larva is aquatic or subaquatic, some of the
species apparently preferring running water. Osten Sacken
found the larva of one species (probably D. defuncta, Os. Sac.,
which, according to Aldrich, = simulans, Walk.) on the woodwork
of a mill-dam, with a stream of water constantly passing over it ;
in fact, that author frequently saw the flies themselves alight on
stones and rocks over which a very thin sheet of water was running.
Winnertz records rearing the Palearctic species D. dumetorum,
Mg., from decaying beech-stumps (Linn. Entom. viii, p. 281).
Lhe perfect insects are found in woods, especially near streams
and small trickling miniature water-falls. They not infrequently
occur in houses, often attracted by an artificial light at night.

The above seems to be the best table that can be drawn up in
the present state of our knowledge, and must not be considered
as a final differentiation of species, still less as a guide to their
affinities. The order in which the descriptions are arranged is
intended to represent the affinities as nearly as can be judged at
present. It is highly probable that the total number of species
occurring in the Indian Empire is double or treble that at present
known. If the genus Thrypticomyia, Skuse, be admitted, the
species in the above table from /obusi to saltans, inclusive, will
come in it.

In the above description the characters of the male are adapted
from Meijere, the female (previously unknown) being described
from a single example of this sex in the Indian Museum from the
Dawna Hills, 2000-3000 ft., 2-3. ili. 08 (Annandale).
Type 3 in the Amsterdam Museum.
Meijere only described the male from a single specimen from
Java, but from the peculiar shape of the wing and the character-
istic venation there can be no possible doubt as to the identity of
the species. The difference in the wings of D. saltans and ewnei-
formis is sufficiently striking when the two species are placed side
by side. Besides being distinctly narrower in cunetformis, the
2nd longitudinal vein originates beyond three-quarters the length
of the wing, and (reckoning from the origin of the 4th longi-
tudinal) the inner end of the discal cell is placed at four-fifths of
the wing’s length, whilst in sadéans it occurs very distinctly before
that distance. In Meijere’s species the veins from the 2nd longi-
tudinal hindwards are much more removed to the tip of the wing
than in saltans.
It may be noted that both Doleschall and Meijere describe the
tarsi of their respective species as snow-white. ‘his is indeed so,
but the basal part of the metatarsus (varying from a third to a
half) is dark, like the tibia. This is apparently an oversight, as
it is not always easy to define the exact limits of each tarsal
joint.
Mr. Edwards refers this species also to Thrypticomyia, a genus
in which the basal part of the wing is extremely narrowed, without
any vestige of an anai angle. Personally I have my doubts of the
validity of Thrypticomyia on account of intermediate forms.

2nd, so that the veins appear crowded towards the tip of the
wing. Halteres pale with black knobs.
Length 4 millim.
Redescribed from four males and one female in the Indian
Museum from Nedumangad, Travancore State, South India,
14. xi.09 (Annandale). The species is also known from Java
and the Philippines, and is most probably generally distributed
throughout the East.
Type. The location of this is unknown, and the probability is
that it is entirely lost. ;
It seems to me that the Limnobia apicalis of Wiedemann is
probably identical with one of the more recently described species
with white tarsi, or else with D. saltans, Dol. If so, the name
will take precedence of all others. Mr. Edwards * calls the
species saltens instead of saltans (the former being the name
given by Doleschal}), and places it in Zhrypticomyia, Skuse,
but the stability of this latter genus appears doubtful, and the
emendation of Doleschall’s name seems legitimised by long usage.

‘“ Head +: antenne brownish, slightly longer than thorax ; 14-
jointed, last joint with the apical joint narrower, so that it has
the appearance of being divided. Joints of flagellum strikingly
pedicillate, the glabrous pedicels occupying from one-third to
one-half the length of the joint, and being only one-quarter as
broad as the broadest part; broad portion more or less conical,
the apex of the cone being towards the base of the joint; these
broad portions are provided with a verticel of fine hairs, three or
four shorter bristles and one longer dorsal bristle, the hairs being
two-thirds, the shorter bristles about one and a half and the longer
about two and a half times as long as the breadth of the conical
portion of the joint. Z’horav ochreous, mesonotum with a rather
broad dark brown central stripe reaching back to the suture.
Abdomen only slightly constricted at base, brown, apical segments

DICRANOMYIA, one
ochreous, venter ochreous. Legs rather dark brown, cox and
femora towards base ochreous, posterior tarsi and apical fifth of
tibie white, tarsi somewhat brownish-tinged at tip; middle tarsi
brown like the femora and tibie. Posterior tarsi scarcely more
than half, middle two-thirds, as long as their tibie. Anterior
legs missing. Wings hyaline, with golden reflections, but less
brilliant than in the other species of the genus; a distinct though
rather diffused stigma. The wing has the typical cuneiform
shape,* but there is a slight indication of an anal angle. Base
of basal cells at one-quarter of wing-length, mediastinal 7 vein
reaching costa much beyond origin of prefurea, about half-way
between that and the apex of the 1st longitudinal vein. Sub-
costal eross-vein close behind apex of mediastinal vein. Marginal
cross-vein and tip of 1st longitudinal rather indistinct, forming
an obtuse angle about the middle of the stigma. Discal cell sub-
quadrate, great cross-vein about one-third of the way along its
lower side. Halteres rather long, stalk ochreous-brown, knob
dark brown.
Length 4:5 millim., of wing 5 millim.” (Zdwards.)
Described from a single female taken at Dondra, Ceylon,
3.x11.07 (1. Bainbrigge Fletcher).
Type in the British Museum.
Mr. Edwards adds: “This species must apparently come in
the genus Z'hrypticomyia, though, like 7’, saltens, it shows con-
siderable divergence from the type, notably in the long mediastinal
vein, the less elongated wings and the less constricted abdomen.
Unfortunately we have no male.”
A character by which this species may be easily distinguished
from the others possessing white tarsi, is that only the hind pair
(“ posterior,” Mr. Edwards terms it) are white, the middle pair
being concolorous with the middle femora and tibie. The fore
tarsi (missing in the type) may be brown or white ; more probably
the former.
This species is retained in Dicranomyia in the present work, as
it seems better placed here. The wing shows a trace of an anal
angle, which in my opinion suggests that other species exist of a
sufficiently intermediate nature to break down this definition as
a generic character. The absence of a supernumerary subcostal
cross-vein also excludes the species from Z'hrypticomyra, Skuse.
The relative lengths of the different veins in species of Dicrano-
myia are very variable. Were it not that the typical species of
Skuse’s genus is represented by six specimens the additional cross-
vein might have been presumed to be accidental.
* Edwards is of course referring to the genus Thrypticomyia, in which he
places his species, and in which the cuneiform shape of the basal part of the
wing is a generic character.

large apical brown spot of irregular shape, its inner edge nearly
parallel to, but distinctly separated from, the 2nd triangular spot ;
its lower edge running horizontally to the margin, just above the
3rd longitudinal vein; an irregular diagonal clear streak near
the centre of this apical brown spot, one end (of the clear streak)
being near the base of the 2nd submarginal cell, the other end

3 2. Head grey or yellowish grey, back of head with numerous
long black hairs. Frons pale yellow, one-fifth the width of the
head ; eyes very narrowly separated on the underside of the head.
Proboscis brown, sometimes black at tip; palpi brown, Ist joint
narrow, cylindrical, 2nd broad, sub-triangular, 3rd and 4th broader
at tip than base, less wide than 2nd, subequal in length. Antennal
scape brown; flagellum pale yellowish or brownish yellow, with
verticels of not long hairs. Zhoraw: neck yellowish, with the
dorsum more or less blackish. Mesonotum pale brownish yellow ;
scutellum and metanotum, and pleure sometimes, a little paler.
From the three examples present, the normal form would appear
to possess a broad brown median stripe, which widens posteriorly,
until behind the suture it occupies nearly all the dorsum, but its
colour diminishes in intensity in that part. One example (ype)
shows only a vestige of this median stripe, the whole thorax in
this individual being pale yellowish. In the female the dorsal
brown stripe is darker and carried uninterruptedly over the
scutellum and metanotum; and there is also a distinct short dark
brown lateral stripe on each side of the thorax. Abdomen
yellowish, with a few pale hairs at the sides; emargination of
segments a little brownish in male. Belly similar. Abdomen
of female brown. Legs: coxe and femora yellowish, the latter

with the tips sometimes slightly blackish; tibie and_ tarsi
brownish. Wings pale yellowish grey, highly iridescent.
Auxiliary vein ending barely beyond tip of 2nd_ longitudinal,
which begins at the “middle of the wing, the prefurca forming
not quite half the length of the vein; basal section of 3rd vein
very oblique, twice as long as the anterior cross-vein; marginal
cell much longer and wider than the submarginal ; discal cell as
long as or a little longer than 2nd and 3rd posterior cells, twice

the humeral cross-vein (sometimes faint), the 2nd over the base of
the 2nd vein, the 8rd over the marginal cross-vein ; another over
the origin of the 83rd vein. The basal and distal sides of the
discal cell are infuseated, as are also both cross-veins, the 5th
Jongitudinal vein throughout its length, the tips of the 6th and
7th veins and, to a slight degree, the tips of some of the other
veins. Halteres paie yellow.

seong, 4.1x. 09 keene) and an additional male and the
type female from Darjiling, 8. vii. 09 (Paiva).
Types 3 and @ in the Traian Museum.
In spite of the differences in the markings on the thorax,
I cannot but regard all three specimens as representing but one
species. The second male example possessing no abdomen, there
is no alternative but to make the one with the thorax nearly
wholly yellow the type of the species. The wing-markings agree
perfectly in all three examples, except that the basal costal spot is
fainter in the type male.
266. Dicranomyia fraterna, sp. nov. (PI. VII, fig. 5.)
9. Very near D. puneticosta, but differing in the following
characters :—
Head: the frons about one-sixth the width of the head, at
its narrowest, and widening rapidly above and below the middle
line. Thorac grey, with a yellowish tinge, and three distinct
brown or brownish grey dorsal stripes (absent in one specimen),
narrewly separated, the median one attaining the anterior margin;
the brownish grey colour continued behind the suture, and the
metanotum of the same shade. Scutellum dirty yellowish white.
Abdominal segments darker brown, with a trace of lighter brown
on the hind margins, especially towards the sides. Ovipositor
reddish yellow. Legs differing from those of D. puncticosta by
the distinctly black tips to the femora, the tibize being more
yellowish. Wings clear, with very pale grey spots placed as
follows :—Just below humeral cross-vein ; over tip of auxiliary
vein, embracing base of 2nd vein; an intermediate costal spot
between these two; a comparatively large one (but no darker)

Although so closely related to D. puncticosta, this form seems
sufficiently characterized by the three distinct thoracic stripes
(although absent in one individual), the black ring on all the
femora, and the clear, not yellowish grey, wing, with a less
number of markings.

uniformly brownish yellow. Wzengs clear. Auxiliary vein ending
immediately before the base of the 2nd longitudinal, which begins
just beyond the middle of the wing; the 1st longitudinal ending
just before the middle of the marginal cell; marginal vein
distinct, placed exactly at the bend in the Ist vein where it
turns up to the costa, this section of it being very indistinct,
making it appear as though the 1st vein turned downwards at its
tip, meeting the 2nd vein; prefurca less than half as long as the
remainder of the vein, tip of vein turned sharply upwards at tip ;
basal section of 3rd vein two and a half times as long as the
anterior cross-vein, which latter is as long as the basal side of
the discal cell ; discal cell nearly oblong, slightly broader towards
the tip, three times as long as broad, rather longer than the 2nd
and 3rd posterior ceils ; posterior cross-vein in a line with base of
discal cell. The markings of the wing consist of pale grey spots
placed as follows :—At the base of the 4th vein; near the middle
of the 4th vein, situated so as to be in the middle of both basal
cells; at the base of the 2nd vein; on the marginal cross-vein,
forming the stigma; and near the tip of the 7th vein. All the
cross-veins are narrowly infuscated, as is also the tip of the
2nd vein and base of the 3rd vein. Halteres whitish, clubs
black, small.

This species must be very near D. punctulata, Meij., from Java,
and possibly identical with it, as the wing-markings agree pretty
closely, so that the only points of difference in the descriptions
appear to be the blackish brown antenne, the short side stripes
on the thoracic dorsum, the yellow coxx, and the yellow base and
the ring on each femur, in D. punctulata, Meijere’s specimen is
slightly larger (4 millim.), and a male.

A good general resemblance to D. fortis is noticeable at first
sight in this species, but the yellowish grey thorax with at least
a distinct dark median stripe, the glassy wings and the dark

Head: eyes separated above by a narrow front, nearly con-
tiguous on underside of head. Proboscis elongate, longer than
the head. but shorter than the head and thorax together, mode-
rately stout, palpi situated at its tip; their first two joints
very short, the 3rd but little longer, the 4th linear, slender,
about as long as the first three taken together; when at rest,
the tip of the preboscis, pointing backwards, reaches but very
little behind the root of the 1st joint.* The antenne, if bent
backwards, would not quite reach the root of the wings; 16-
jointed, Ist scapal joint long, 2nd subglobular, both conspicuous ;
flagellum somewhat incrassated at its base, the joints subcylin-
drical, short, more elongated towards the tip, verticels moderately
long. Thorax somewhat broad in front, prolonged into a short
but distinct neck; thoracic suture deep. Abdomen normal.
Genital organs of the male consisting of a basal plate, a pair of
claspers ending in two horny hooks on each clasper. Ovipositor
of female of the usual structure. Legs long, slender, finely
pubescent ; tibiae withont spurs at tip; empodia indistinct, ungues
smooth. Wings moderately long, broader or narrower in different
species ; with one submarginal cell, four posterior cells, and a
discal cell ; 2nd longitudinal vein not forked. The auxiliary vein
ending opposite the inner end of the submarginal cell, sometimes
in the costa, sometimes turned down at the tip into the Ist
longitudinal at some distance anterior to the tip of the latter.
Subcostal cross-vein, when present, at tip of auxiliary vein ; some-
times obsolete; no marginal cross-vein; stigma present or
* This is according to Osten Sacken, referring to the North American
species 2. flavipes, as examined by him in a living specimen. He adds that
Meigen’s illustration (Syst. Besch. vi, pl. lxv, fig. 8) gives a correct impression
of the palpi, so presumably the characters are sufficiently definite to regard
them as generic.
+ Osten Sacken says “in some specimens the subcostal cross-yvein is obsolete ;
in such eases the auxiliary vein ends in the Ist longitudinal and not in the
costa.” Whether by the use of the word “specimens” and not species he intends
to infer that this occurrence is adventitious, is not clear. In one of the two
Orienta: species (2. ferruginea, Brun.), the auxiliary vein ends in the Ist
longitudinal vein just beyond the proximal end of the submarginal cell, at a
considerable distance beyond the origin of the 2nd vein, and some distance
before the tip of the Ist vein.

absent ; the 2nd longitudinal vein beginning about the middle of
the wing (somewhat before the middle in 2. ferruginea) ; preefurca
longer than the remainder of the 2nd vein, but sometimes longer,
sometimes shorter than the 3rd vein; the 3rd vein gently curved
or straight ; the submarginal cell broader at the tip than at the
base; * basal part of 3rd vein very short (almost punctiform
in ferruginea). Occasionally the anterior cross-vein is absent,
and when this is the case the submarginal cell is in direct
contact with the discal cell.f Discal cell approximately oblong,
or of irregular shape ; posterior cross-vein just beyond base
of discal cell; the 5th, 6th, and 7th longitudinal veins gently
curved.
Range. Europe, West Indies, South America, Australia, and
the East.
This genus is very closely allied to Elephantomyia, Os. Sac., of
which four species are known to exist in the Orient, although it
does not appear to have been taken within the region covered
by the present volume. ‘The principal difference is that in
Elephantomyia the proboscis is very slender and enormously
prolonged, to a length equal to that of the whole body; the
palpi being extremely small and very easily overlooked, and
placed near the tip of the proboscis. The venation is almost the
same as in Rhamphidia, including the absence of the marginal
cross-vein.
Life-history.—The larva of one European species (2. longi-
rostris, Mg.) lives in the stems of Rumea aquaticus according to
Mr. Gereke, who believes that it lives under water.t
Four species were recorded by Loew from Prussian amber
(‘ Bernst. u. Bernst.-fauna’), but Osten Sacken noted that he had
not seen them himself and that they might not belong to this
genus in his acceptation of it.
Two other names have been suggested to supplant the name
Rhamphidia for this genus: Megarhina, St. Fargeau (1825),
which in the index to the same volume he changed to
Helius; while Stephens in 1829 proposed Leptorhina (in
Curtis’s British Entomology) for the European species longi-
rostris. Meigen described the genus under its present name in
1830 (Syst. Besch. vi, p. 281), and it is very satisfactory to at least
the author of the present work, to find that the wholesale icono-

+ This occurs in the European 2. longirostris, Wied., and the North American

3rd vein with the 2nd in R. ferruginea foreshadows the disappearance of the
anterior cross-vein altogether, as happens in the two non-Oriental species noted
here.

The form of venation shown in this species, 7. e., the absence of
the subcostal cross-vein and the ending of the auxiliary vein in
the 1st longitudinal, is distinctly noted by Osten Sacken in his
monograph of the North American TipuLIp® BREVIPALPI. The
absence of the marginal cross-vein is a generic character. The
abnormal slenderness of the last few juints of the antenne is
very striking.

it gradually converges towards the costa, eventually being merged

myia, as demonstrated by the elongate proboscis and the absence.
of the marginal cross-vein. Toworhina, by its venation, which is
different from that of any other genus in the family, is easily
recognised from either.
Osten Sacken, after his very ample description of this genus in
his monograph of the North American species, enters at some
length on the question of whether the generic name should stand
for the single living species known to Loew (fragilis, from Porto
Rico), described in 1851, or for three fossil species described by
him (Loew) from amber in 1850, for which no generic description
was given.

‘hough the discal cell is open and there is no mention of this
being the case in any of the three living species of the genus, there
can be no possible doubt of the present form being a Toxorhina in
the fullest sense. In every other way the venation agrees with
Osten Sacken’s plate and description. The gradual absorption
the costa of the lst longitudinal vein, the entire absence of the
3rd vein (in itself a character of quite exceptional occurrence),
are very strong generic characters. Moreover, the enormously
prolonged rostrum ; the absence, so far as I am aware, of palpi
(Osten Sacken says they are very minute, with coalescent joints) ;
the enlarged mesosternum, causing a considerably larger distance
than usual between the fore and middle coxe; and the peculiar
form of the antenne, agreeing exactly with Osten Sacken’s
description, all combine to make this species a Toxorhina with
practical certainty.

narrow and elongate, with one submarginal and four posterior
cells, and an open discal cell coalescing with the 2nd posterior
cell; posterior cross-vein near the middle of the wing ; the
auxiliary vein ending in the costa a little before the inner end of
the submarginal cell, and some distance beyond the origin of the
2nd longitudinal vein; the tip of this vein (auxiliary) ‘thickened,
running “obliquely into the costa and strengthening it; the Ist
longitudinal ending some distance beyond ‘hes tip of ine auxiliary,
joining the costa some little distance before the tip of the wing ;
the 2nd vein beginning about the middle of the wing, quitting the
Ist at a sharp angle, thence turning suddenly and running nearly
straight to the margin, the preefurea forming nearly or quite half
the length of the vein; marginal cross-vein just beyond the
middle of the marginal cell; the 3rd vein starting at an angle,
running nearly parallel to the 2nd vein; the anterior cross-yein
situated soon after the origin of the 3rd vein, a little behind the
marginal eross-vein, joining the upper branch of the 4th vein soon
after its origin ; the lower branch of the 4th vein forked, the
discal cell open, coalescing with the 2nd posterior cell; posterior
cross-vein placed near the middle of the wing just beyond the
origin of the 3rd vein, thus much shortening the 2nd _ basal cell
and correspondingly ereatly lengthening the Sth posterior cell,
which is twice as long as the ond posterior and nearly three times
as long as the 3rd ; she 5th, 6th, and 7th veins nearly straight,
the two former closely approximate for the first third of their
length.
Range. Kurope, Australia, and India.
Orimarga has affinities with Dicranoptycha, from which it is
easily distinguished by the unusual position of the posterior cross-
vein and the absence of the discal cell, which in Dicranoptycha is
present. Osten Sacken sees affinities with Toxorhina in the
oblong thorax, which is narrow when seen from above; in the
somewhat elongate neck; and in the extra development of the
mesosternum.

Auxiliary vein ending just beyond half the distance between the
origin of the 2nd vein and the marginal cross-vein ; the 2nd vein
beginning just before the middle of the wing, the preefurea being
two-fifths of the length of the vein; marginal cross-vein exactly
in middle of marginal cell, half-way between the tips of the
auxiliary and Ist veins ; the 3rd vein originating a little before

the origin of the 3rd vein, it is, in some species, angled again, the
remaining part being as long as the prefurca; the 3rd vein as
long as, or a little longer than the apical half of the 2nd vein,
gently bisinuate ; anterior cross-vein placed at the middle of the
discal cell or at its proximal upper corner, opposite the marginal
cross-vein ; discal cell approximately rhomboidal or of irregular
shape (pentagonal in opalizans, Os. Sac., of North America), a
little less in length than the 2nd and 3rd _ posterior cells, though
this proportion probably varies with the species; posterior cross-
vein situated at the base of or distinctly before the base of the
discal cell; the 5th vein absolutely straight, the 6th and 7th

wings are said to have a milky white tinge, but this is not very
apparent in the two Oriental species at present known.

The species of this genus have a facies peculiarly their own,
and amongst a general collection of Tirunrpm can easily be
recognised, once the genus is understood. ‘heir well-set, robust
appearance, subgibbous thorax, long neck, comparatively short,
robust hairy legs, very clear wings (in the hyaline parts), short
auxiliary and Ist longitudinal veins, with the general distinctness
of all the veins, characterise them as a well-defined, homogeneous
group.

(Osten Sacken.)
From an examination of a good series of males and one or two
females in the Indian Museum, the following notes may be
appended to Osten Sacken’s s description.
The dorsum of the thorax is more often wholly ferruginous
than otherwise, a distinct stripe, much less three, being apparently
the exception, although there are not infrequently indistinct
brown suffusions in parts. The legs are sometimes dark yellowish
brown, the coxw occasionally reddish yellow, and the subhyaline
spaces in the wings are mostly indistinct or absent.

dale); Naini Tal, 14-17.iv.07; Khasi Hills, Assam ; Mazbat,
Mangaldai district, Assam, 11-15. x.10 (Kemp); Peradeniya,
Ceylon, 26. vii. 10 (Gravely), one of the very few females seen by
me. It is in the Pusa collection from Darjiling, 3-9. vi. 09

This is evidently an Atarba, the discrepancies from the three
North American species of w hich figures are accessible being very
small. Moreover, slight differences in the venation of these
three species, A. puella, Will., pleuralis, Will., and picticornis,
O.S., are apparent. With Osten Sacken’s generic description
this species entirely agrees, and it only varies in venation from
Needham’s figure of picticornis by the posterior cross-vein being
placed nearly at the middle of the discal cell instead of in a line
with its basal side.
In picticornis, too, the auxiliary vein reaches some short distance
beyond the origin of the 2nd longitudinal, and the veins running
to the distal wing-margin are practically parallel, or only very
slightly divergent, “poth these characters s coinciding with those of
flava. In the other two North American species mentioned, the
2nd vein curves distinctly upward, especially in plewralis, whilst
the 3rd vein very distinctly curves downward making the sub-
marginal cell very widely open on the wing-margin; whereas in
both flava and picticornis both veins are almost exactly equidistant
from each other and from the Ist longitudinal and anterior branch
of the 4th longitudinal respectively.
Section HRIOPTERINI.
Eyes bare, separated above by a more or less wide frons,
contiguous or approximate on ‘the underside. Antenne 16-
jointed. Tibize without apical spurs, empodia distinct, ungues
smooth on the underside.
Wings with two submarginal cells; four, sometimes five,
posterior cells; discal cell closed or open (very variable in some
genera, often in the same species). In many genera the veins
are distinctly pubescent (to a varying extent in some genera,
such as Erioptera, according to the “species) ; in others the
surface of the wings, as w ell as of the veins, is covered with
hairs.
The subcostal cross-vein is sometimes placed at a considerable
distance anterior to the tip of the auxiliary vein (Zrioptera,
fond
ERIOPTERINI. 437
Lthypholophus), sometimes not much before it or near its tip
(Gonomyia, Empeda, Gnophomyia, Symplecta). This difference
occurs in unquestionably closely allied genera. For instance, it
is quite a long distance before the tip of the auxiliary vein in
Paracladura, Brun., and Claduroides, Brun., yet only a little
before the tip in Cladura, Os. Sac. This very distinct differ-
ence of position of the subcostal cross-vein in undoubtedly allied
genera indicates that the importance of this character has been
overestimated by some authors.
The 2nd longitudinal vein presents a peculiarity in one group
of genera, by the upper branch being almost upright, thus having
much the appearance of a cross-vein ; in fact, some of the older
authors regarded it as such. This is the principal character of
the Gonomyia group, which includes, besides Gonomyia, Empeda,
Monogoma, and two new genera constructed by me out of the latter,
Paramongoma and Mongoméoides. An intermediate genus, Gno-
phomyia, with the upper branch of the 2nd longitudinal vein not
upright, but more or less parallel with the lower one, may be
regarded as joining the Gonomyia group to the Hrioptera group,
as some authors consider; or as forming a link between the |
Gonomyia group and the section Limnopureist, my own opinion
inclining towards this latter view.
Altogether this section is rather a mixed one, and although it
may be considered as intermediate between the Limnoprint and
the LimnopHinini, it may, speaking more narrowly, still be
regarded mainly as a collection of groups.
These groups (referring to the Oriental genera only) may be
considered to be three in number. One, the Cladura group, is
characterised by the presence of five pesterior cells, by which the
genera may be easily differentiated from all others. They are
Cladura, Paracladura and Claduroides, with a rather aberrant
genus Conosia, Wulp, which, however, undoubtedly belongs here
by virtue of its five posterior cells. The second group is formed
of the genera surrounding Hrioptera, including Rhypholophus, Kol.,
Molophilus, Curt., and Mesocyphona, Os. Sac. The most con-
spicuous character of this group is the presence of stiff hairs
along at least the posterior portions of all the veins; whilst one
genus (Ithypholophus) has the membrane of the wing also closely
pubescent.
The remaining group centres round Gonomyia, and is promi-
nently distinguished by the upright or nearly upright position of
the anterior branch of the 2nd longitudinal vein, which appears
almost as a cross-vein, thus making the Ist submarginal cell only
about half as long as the 2nd. The genera comprised form a
tolerably compact group ; they are, Gonomyia, Empeda, Monogoma,
and my two new genera constructed from it, with the addition of
two rather aberrant genera, which, however, undoubtedly belong
here, namely, Lechria, Skuse, previously only known by one
species from Australia, and the equally abnormal genus Styrinyo-
myta, Lw., which till 1887 was known from a fossil species only.

438 TIPULID 2.
In that year Osten Sacken mentions an undescribed recent
species in the Stockholm Museum from Caffraria.
These two genera, though distinctly abnormal, are eminently
related to Gonomyia and its allies by the position of the anterior
branch of the 2nd longitudinal vein and also by irregularities
concerning the 3rd longitudinal vein and the anterior cross-vein.*
Gonomyta, in certain species, foreshadows these irregularities,
including that of the absence of the anterior cross-vein, for it
comprises species possessing either one or two submarginal cells,
and exhibits a variation of venation which makes it suitable as a
central genus around which to arrange the others. This variability
also is suflicient to prevent its dismemberment, since all the
species show suflicient resemblances to retain them under one
genus,
I retain Gnophomyia, Os. Sac., and Symplecta, Mg., together,
in accordance with recent Catalogues, but it has often occurred
to me that Gnophomyia, with its greater degree of “ parallelism ”
in the veins, and its posterior cross-vein near the middle of the
discal cell, was in some way a connecting link between Gonomyia
and the LimnopHixint, whilst Symplecta, by its general appearance
and its posterior cross-vein before the discal cell, reminds one
rather strongly of the LimNoprnt, although its place in this
section cannot, of course, be questioned.

GENOTYPE, Lthypholophus phryganopterus, Kol.
This genus is closely allied to Hrioptera, the principal differential
character being that the wings are pubescent over the whole
surface, pactentl of only along the veins, as is the case in all the
other genera of the Hrioptera group found in the East. There
are two submarginal cells, féur posterior cells, and a discal cell,
which is open or closed. The antennz are of sixteen joints, and
are of considerable length in the males of some species,* the joints
being much elongated, strongly pedicelled and pubescent. A
discal cell is present or absent; when the cell is absent it is
generally the anterior branch of the 4th longitudinal vein that is
forked, the cell being then coalescent with the 3rd posterior cell. +
The wing is, generally speaking, slightly broader than in Erioptera,
and the veins diverge from each other rather more distinctly, so
that they do not present the peculiar effect of parallelism so
conspicuous in Hrioptera. The 7th longitudinal vein is normally
straight, or slightly arcuate, bending downwards or more or less
abruptly curved downwards in its middle, presenting its concavity
towards the 6th vein. Occasionally ¢ it runs comparatively near
to the 6th vein in its basal part, but never so pronouncedly so as
mm the typical Hrioptere.
Range. The previously recorded species occur in Europe and
North America, extending into the Arctic Regions, several species
coming from Greenland and Alaska.
* This does not occur in the Oriental species.
+ These species were placed in the genus, Dasyptera, formed for their reception
by Schiner, but our more extended acquaintance with the Diptera has proved
that the presence or absence of a discal cell is seldom of generic value unless
accompanied by other constant characters. It is not always the anterior
branch of the 4th vein which is forked, when the discal cell is absent, as in
at least one North American species (J?. holotrichus, Os. Sac.) the posterior
branch bears the fork.

considerably pubescent. Antennal scape pale yellow; flagellar
joints elongate oval, rather thickly pubescent, with pale brownish
yellow hairs, brown, tips pale yellowish white, the joints becoming
longer and narrower towards the tips of the antenne. TZ'horaw

usual shorter dorsal stripes oecur; darker also behind the suture ;
a-small shining elongate black spot in a small depression on each
side of the middle, a little before half-way between the anterior
margin and the suture. Thorax pubescent, with short yellow
hairs, and a dorso-central stripe of irregularly placed longer
thicker yellow hairs along each side of the middle, well separated.
Scutellum with yellowish hairs. Abdomen black, with compara-
tively thick yellow pubescence. Genitalia large, black, the
lst joint of the claspers oval, the remaining appendages
apparently small. Legs: anterior legs dark brown or biack,
with short pnbescence, which in certain lights appears golden’
yellow; a moderately broad band of very short golden yellow
hair at tips of femora, extending in some cases to the base
of the tibie; tips of tibia with a very narrow similar band ;
the hind tibiw changing rapidly before the middle to yellowish,
with short distinct yellow pubescence, and the whole of the hind
tarsi yellowish, with concolorous pubescence. Wings very pale
yellowish grey, rather thickly covered with short black hairs,
with which are intermixed, in places, short golden yellow ones,
there being no distinct stigma, but the yellow hairs are especially
prominent in that part of the wing. The black hairs are arranged
so that they form four more or less distinct, though not well-
defined, bands of about equal width, with a rather narrow interval
between each; the first band basal, the fourth apical, the second
ending distinctly before the cross-veins, at which latter spot the
tnird begins ; the yellow hairs more numerous between the bands
of black hairs. Halteres yellow.

(1863).
Gunoryee, Erioptera atra, Mg. (brevipennis, Curt.).
Molophilus possesses the general characters of Hrioptera, to
which it is intimately akin, and from which the principal separative
character is the peculiar but very distinctive one of the 3rd longi-
tudinal vein issuing from the lower branch of the 2nd longitudinal
vein, instead of from the prefurca of that vein, as is usually the
case in the Erioprnrini. This causes the 1st submarginal cell
to be distinctly, though not greatly, longer than the 2nd. The
4th longitudinal vein forks much sooner than in Hrioptera, much
before the anterior cross-vein, the posterior cross-vein being just
beyond the fork of the 4th vein. This causes the 2nd posterior
cell (as the discal cell is always absent, so far as I am aware) to
be;much longer than the Ist or the 3rd cell. Marginal cross-vein
just beyond the fork of the 2nd vein; basal section of 3rd vein,
and the anterior cross-vein in a line. Posterior branch of the
4th longitudinal forked, the branches long and nearly parallel.
The 5th, 6th, and 7th veins nearly straight, the latter long, but
without any tendency to approach the 6th nor running parallel
to the hind margin of the wing, as is characteristic of the typical
Oriental species of Hrioptera.
Range. Europe, North America, and Australia, in addition to
the forms herein described.
This genus was founded by Curtis for what he described as
M. brevipennis, Curt., but which subsequently was found to be
synonymous with Hrioptera atra, Mg.* Although Osten Sacken
disagrees with the generic value of the characters 7 attributed to
* Osten Sacken (Monog. Dipt. N. Amer. p. 148) distinctly calls attention
to the fact that the synonymy adopted by European authcerities must have
been based on a comparison with the types, because Curtis’s description and
that of Z. atra, Mg., would not lead an independent worker to the opinion of
their identity.
t These were, the small size of the wing, the modified shape of the thorax
and abdomen, and the large male genitalia.

for the group of species to which Z. atra belongs, and this view

subcontiguous beneath. Proboscis short, stout ; palpi eompara-
tively short, the middle joints rather stouter. Antenne generally
rather short, * of sixteen joints; the Ist scapal joint varies in length
but is nearly always wider at the tip; the 2nd is considerably
enlarged, much the widest of all, rounded, subeylindrical or ovate,
occasionally of irregular shape; 1st joint of the flagellum often
onion-shaped, and often much larger than the remaining flagellar
joints, which are oval, more or less, becoming considerably elon-
gated towards the tip of the antenna, the whole flagellum closely
pubescent, each joint bearing a verticel of long hairs. Thorax
somewhat high and convex, produced forwards conically into a
short blunt neck, which is inconspicuous in some species. Two
well-separated rows of dorso-central stiff hairs, which, beyond the
suture, generally diverge towards the posterior corners of the
dorsum.t ‘Thoracic suture distinct, and the post-sutural depres-
sion rather well marked. Abdomen linear, of moderate size, often
transparent, when the internal organs can be rather easily seen.
Genitalia of male consisting of a large fleshy basal joint which is
usually ovate or subcylindrical, and to which is appended some-
times a single horny hook or bifid claw, sometimes a second joint,
much smaller, bearing a terminal hard piece of some kind. Dif-
ferent intermediate small organs appear to be present in some of
the species, but they are not easily examined in dried specimens.+
The ovipositor in the female differs in length considerably ; the
upper pair of valves long, slightly curved upwards, the lower pair
set further back at their base, generally much shorter, and straight,
both pairs enlarged, in some species to a considerable extent, at
the base ; two small horny projections are placed at the base of
the upper pair of valves.§ Legs slender, of moderate length
or rather short, pubescent, often very conspicuously hairy ; the
middle pair generally shorter than the others; tibie without
apical spurs, empodia distinct, ungues smooth on the inner side ;
the last joint of the tarsus is said to project somewhat over the
ungues. Wings rather broad, tip rounded; veins pubescent,
especially towards the apical half of the wing, but the hairs
much more conspicuous in some species than in others. ‘Two
submarginal cells and four posterior cells, the discal cell open
or closed; the veins mainly parallel on the outer side of the
wing ; the auxiliary vein ending beyond the middle of the wing,

sometimes at nearly three-fourths its length ; the Ist longitudinal
vein ending some distance beyond the tip of the auxiliary ; the
2nd vein beginning some distance before the middle of the wing,
at an acute angle, the first part of the prefurca (that is, up to the
origin of the 3rd vein) much longer, often double as long, as the
remainder (up to the fork); the vein forks soon after the origin
of the 3rd vein, the branches more or less paraliel, the marginal
cross-vein situated just after the fork; the 3rd vein emerging at
a wide angle, the basal section of about the same length as the
anterior cross-vein; the 4th longitudinal forking at or almost
immediately before, the anterior cross-vein ; the anterior branch
simple, the posterior branch forked soon after quitting the cross-
vein, the veinlets sometimes parallel, sometimes diverging, their
tips having a tendency to turn upward slightly ; posterior cross-
vein lying from a little before to a little after the forking of the
2nd vein; the 5th and 6th veins nearly straight, the 7th running
for a considerable distance close to and parallel with the 6th, and,
after turning down to the margin, running (more or less sinuously )
parallel with the hind edge of the wing. This character is not
invariable, as in some species it is nearly straight, in others,
although approximate in its basal half to the 6th, it afterwards
turns straight down to the wing margin without running along-
side of the latter.

In his Monograph (p. 146) Osten Sacken goes very fully into
the question of the synonymy of Hrioptera and the closely allied
genera Rhypholophus, Kol., Molophilus, Curt., Acyphona, Os. Sac.,
and Mesocyphona, Os. Sac. He seems to have had grave doubts
about admitting to generic rank any of these subsidiary genera
except Molophilus. Referring to the genus Hrioptera, which he
divided into the following subgenera, Hrioptera, Acyphona, Hoplo-
labis, Mesocyphona and Molophilus, he says: ‘If I have retained
them in the position of groups or subgenera it is because, in my
opinion, the characters which all these species possess in common,
constitute between them a link of affinity more important than the
structural differences which some of them show”.* In his later
work on the genera of Tiputtp® he adheres to this view, with
the exception of finally accepting Molophilus as distinct, owing to
the peculiar origin of the 3rd longitudinal vein from the posterior
branch of the 2nd vein instead of from the prefurca, as in most
ERIOPTERINI.
Erioptera, as I understand it, is now retained for species in
which the 4th longitudinal vein has its posterior branch forked,
the discal cell open, coalescent with the 2nd posterior cell, and
the 7th vein often (though not in all cases) with the peculiar
character of running alongside the 6th for some distance, and

then after turning more or less suddenly downwards towards the
hind margin of the wing, running approximately alongside of that
iso, although the apical half of the 7th vein itself in such cases
is sinuate or bisinuate.
Mesocyphona ditters mainly by the anterior branch of the 4th
longitudinal vein being forked instead of the posterior one, so
that the discal cell, being absent as such, is coalescent with the
3rd posterior cell. The 7th vein appears to be straight, the only
species other than my new one, UW. nigripes, with which 1 have
the means of comparison, being J. caloptera, Os. Sac., of which
Needham gives a figure.
Acyphona and Hoplolabis, not being Oriental, may be passed
over with the remark that the closing of the discal cell, fore-
shortening the 2nd posterior cell, is the only generic character of
the former, whilst the appendix in the diseal cell in addition to
the position of the posterior cross-vein (some distance before the
discal cell) are the characters of the latter. Of course, either or
both these forms, whether they are to be considered good genera
or not, may easily occur in the East. Acyphona occurs in Central
Europe, Hoplolabis in the United States.
Molophilus is quite a good genus by virtue of the unusual origin
of the 3rd vein, coupled with the extension proximally of both
the 2nd posterior cell and the posterior cross-vein.
Rhypholophus is again easily separated from all the above
genera by the membrane of the wings being hairy in addition to
the veins.
In Erioptera, sensu stricto, some variation of importance in the
course of the 7th vein is recorded above, and those species in
which this vein assumes its peculiar and unusual course may be
regarded as the typical ones of the genus in the East. In the
degree of pubescence of the veins, much difference is seen, some
species appearing at once as hairy-winged, whereas in others the
wings appear at first sight practically bare.

auxiliary vein and the Ist longitudinal lie so near the costa as
to be hardly visible; the 2nd longitudinal vein beginning at one-
third the length of the wing, forking beyond the middle, the
upper branch forming a rectangle at its origin, both branches
running parallel with the margin of the wing; the very short
marginal cross-vein placed at the angle in the upper branch; the

This species resembles /. halterata in general appearance,
especially in the black-clubbed halteres. It is, however, easily
distinguished by several apparently good characters: by the
inconspicuous pubescence of the veins ; the ferruginous shining
thorax, lightly though distinctly striped with black; the different
position of the posterior cross-vein ; the short 7th vein turning
down somewhat sharply to the margin instead of running parallel
with it for a considerable distance, as in FE, halterata. Also the
fork of the lower branch of the 4th vein is different, lying beyond
the middle of the vein, and being widely open, with the veinlets
quite straight.

segment pale dirty yellow, the remainder black. Genitalia some-
what concealed by a pair of large blackish curved plates; yellowish,
two-jointed, hairy, with two small filamentous appendages and an

middle of the wing, the prefurca being nearly two-thirds- the
length of the vein ; the marginal cross-vein placed at some distance
before the rather widely open fork; the 3rd vein originating at
the middle of the przefurca, its basal section distinct, nearly as long
as the anterior cross-vein; the 3rd vein and the upper branch of
the 4th longitudinal are parallel ; the basal end of the 2nd posterior
cell pointed; the lower branch of the 4th longitudinal forked at
one-third of its length, making the 3rd posterior cell elengate-
triangular; posterior cross-vein placed immediately before the
branching of the 4th vein; the 5th, 6th and 7th veins nearly
straight. Halteres pale lemon-yellow.
Length 2 millim.

especially the abdomen, and the pale yellow hairs are more
numerous ; the thoracic dorsum has two distinct rows of long
yellow dorso-central hairs. The genitalia are a little more
elongate. The wing has the 7th vein not approximate to the 6th

before the middle of the wing; the anterior cross-vein barely
beyond the middle; the 4th vein forking immediately before the
anterior cross-vein, the posterior cross-vein placed immediately
before the fork ; the lower branch of the 4th vein forking early ;
all these veins practically parallel, and from their extra length, due
to the cross-veins being so near the middle of the wing, the
appearance of parallelism is striking; the 7th vein running ex-
ceedingly close to the 6th vein at the base (the 5th and 6th veins
are stronger than usual, and distinctly united at their bases), and
afterwards running nearly parallel with the wing-margin, at some
distance from it, whilst still remaining more or less parallel to the
6th vein; the 5th, 6th, and 7th veins all seem rather closer
together in this species than in others. Halteres rather large,
with narrow yellow stems and black clubs.

thorax generally more yellowish than the anterior half. Abdomen
brownish or brownish yellow, hind margins and sides of segments

with the 83rd vein, the 1st posterior cell being shghtly narrow at the
tip; the lower branch widely forked at half its length; the
posterior cross-vein placed just before the fork of the 4th vein ;
the 5th and 6th veins nearly straight; the 7th, after quitting the

being the first of the two species placed by Osten Sacken in the
genus at its installation.
The author separates this genus (which he always regarded as
a subgenus only) from Hrioptera as follows :—‘‘ The anterior branch
of the 4th longitudinal vein is forked; in other words, when the
discal cell is open it coalesces with the 3rd posterior cell ; when
the discal cell is closed, the inner ends of the 2nd and 3rd
posterior cells are nearly in a line.”
The 7th longitudinal vein is straight, and not approximate to
the 6th towards the base, nor more or less parallel with the hind
margin of the wing in its apical section, as is the case in the
typical Oriental species of Hrioptera. In commenting upon the
two North American species on which he founds the genus,*
Osten Sacken notes their further resemblance in the position of
the two brown stripes on the thorax and in the dark bands on
the whitish femora. These characters, however, do not occur in
the new species, MJ. nigripes, here added to the genus. (See
footnote, p. 448.)

3. Head moderately dark grey; frons forming one-third the
width of the head at a little above the antenne, but rapidly
widening towards the vertex, where it forms half the width of
the head ; colour grey, with rather long stiff black hairs ; back of
head dark grey, with moderately long black hairs. Proboscis
brownish yellow; palpi blackish, comparatively large. Antenne
with the 1st scapal joint long, cylindrical, the 2nd subcylindrical,
both blackish ; the flagellar joints oval towards the base, the middle
and apical ones considerably elongated, each with a verticel of very
long hairs in addition to the short ordinary pubescence. Thorax
very arched, making the height, seen in profile, much greater than
usual. Dorsum black, narrowly edged with yellow, this colour

extending a little on to the shoulders. Scutellum more or less
yellowish; metanotum black. Sides of thorax almost wholly black.
Abdomen blackish, roughened, with very sparse short pale hairs ;
belly black. Genitalia very small, black, consisting, so far as can be
seen, of an upper and a lower pair of fleshy subcylindrical one-
jointed claspers, no terminal hooks being evident; moderately
pubescent. Legs black, shortly pubescent. Wings pale grey, veins
biack, pubescence on the veins distinct but not conspicuous. ‘The
auxiliary vein ending much beyond the base of the 2nd longi-
tudinal vein, nearly opposite the base of the 3rd vein; the 2nd
vein beginning before the middle of the wing, forking beyond
half its length, the lower branch nearly twice as long as the
upper one; the 1st longitudinal vein ending beyond the fork of
the 2nd vein; the 3rd vein beginning at two-thirds of the length
of the prefurca, its basal section being half as long as the
anterior cross-vein, running to the tip of the wing ; the 4th vein
has its anterior branch forked at one-third of its length, the
branches nearly parallel, so that the 1st posterior cell has its sides
also approximately parallel ; the 3rd posterior cell with a distinct
basal side, the posterior cross-vein in a line with it; the 5th and
6th veins nearly straight; the 7th not approximated to the 6th
at any portion of its length, and gently arcuate. Halteres dirty
yellowish white.

Gernotyes, S. venusta, Lw.; by original designation. Though
this is a fossil species, it is actually the original type of the genus.
Further extinet species in amber, from Caffraria, were described
by Osten Sacken but not named.
Head: eyes separated above by a broad frons, nearly contiguous
below. Proboscis short; palpi four-jointed, the joints more or
less of equal length, generally the 1st joint the shortest and the
last the longest. Antenne rather long, 16-jointed ; scape with
1st joint elongate, cylindrical, the 2nd broader and much shorter ;
the flagellum of fourteen oval joints, gradually diminishing in size
to the tip. Thorax oval, moderately arched ; prothorax conically
produced into a normal short neck. Abdomen long (sometimes
three times the length of the thorax), linear, composed of only
seven segments, a short basal one and six others about equal in
460 TIPULID®.
Jength. Genital organs of male prominent and complex; a large
pair of thick fleshy claspers with some appendages, and a secondary
pair of claspers. In the female the genital organs are also large
and rather more complex than usual. Legs comparatively short
and stout, rather conspicuously hairy; tibize without apical spurs;
empodia distinct. Wings: auviliary vein absent, probably united
with the basal part of Ist longitudinal vein w here the latter is
slightly thickened and takes a sharp bend downwards, afterwards
ending in the costa before the middle of the wing; 2nd vein
emerging from towards tip of Ist and forming a wide sweep, or
the apical part is turned up rather suddenly to the costa, ending
in it about half-way between the tip of the Ist vein and the wing-
tip; 3rd vein originating at two-thirds the length of the 2nd and,
atter the usual bend, running straight to above the wing-tip ;
anterior cross-vein of moderate length, in a line with the basal
section of the 3rd; discal cell approximately oblong, twice as long
as broad; upper branch of 4th vein forked at or immediately
beyond discal cell, the veinlets diverging, lower branch simple ;
posterior cross-vein at middle of discal cell; 5th, 6th and 7th
veins all long and nearly straight. Through the absence of the
auxiliary vein there is a cell less than usual in the anterior part
of the wing, those present being the costal, marginal, and sub-
marginal (one only) with four posterior cells.
Range. Hawaii, Java, India, Ceylon, and Tropical Africa.
Fossil species in amber from Zanzibar and Caffraria.
The genus was described by Loew in 1845 from a apache in
amber, aad was for many years considered an extinct genus. - The
late Baron Osten Sacken, in his Monograph of the North
American TIPULIDZ BREVIPALPI (p. 102), describes a second
species (without naming it) from a piece of copal from Zanzibar.
He figures a wing, copied from Loew’s figure, and characterises
the genus, adding from Loew's original description such details
as were not distinctly visible in his own species. He suggested,
but did not assume, the relationship of the genus to Zoworhina.
Later on (1887) the same author, in his historical *‘ Studies on
Tipulide,” 11 (Berl. Ent. Zeits., xxxiii, p. 185), records the exis-
tence of recently captured specimens from Caffraria taken by
Wahlberg, in the collection of the Stockholm Museum. Needham
(New York State Museum, Bulletin 124, pl. xxvi, fig. 6) repro-
duces an enlarged figure of Osten § Sacken’s copy of Loew's wing.
Prof. Kertész in his exhaustive catalogue of the Diptera of the
World, now in progress of publication, does not mention the genus,
from which I presume that the Caffraria specimens were not
named. Loew’s original species was S. venusta, Q.
Incidentally it may be noted that there exists another genus
with a very similar name—Steringomyia, Pokorny—erected in
1889 (Verh. zool-bot. Ges. Wien, xxxix, p. 568) for a single
species from the Alps, allied to the genus of Muscipm, Cynomyia,
Rob. Desy.
STYRINGOMYIA. 461
De Meijere places the genus in the Rrampurprins, but it seems
to me much more nearly related to the Gonomyia group, with
Mongoma, Lechria, and the closer allies of Gonomyia.

2nd pointed posteriorly above ; this latter segment bearing a pair
of large subchitinous claspers of which the upper arm is bluntly
conical, terminating in a black sharp elongated point ; the lower
arm being attenuated, elongated, nearly transparent, apparently
flexible and terminating in a very long black filamentous bristle;

nearly perpendicular sheaths, terminating in filamentous points,
and enclosing two internal lamella and two bristly fleshy organs,
the whole being supported below by a ventral plate which
possesses a small appendage towards the tip, below. In both sexes
the genital organs are conspicuous and large, generally concolorous
or a little lighter in colour than the abdomen. Legs mainly

Originally described by Mr. Edwards from a single male from
Weligama, Ceylon, 9.11.08 (7. Bainbrigge Fletcher); here redescribed
from a pair in the Indian Museum taken in cop. at Sukhwani,
Nepal, 15.-16. ii. 08 ; a pair im cop. from Puri, Orissa, 10. xi. 10
(Annandale) ; a pair wi cop. taken at light 30. vii. 10 (Gravely) ;
a pair taken at Sukna, Darjiling district, 500 ft., 1. vil. 08 (Annan-
dale); and from other specimens.
Type 3d in the British Museum.
The above description was written some months before the
publication of Mr. Edwards’ S. ceylonica, under the assumption
that it was a new species, having been drawn up from a
series of more than a dozen specimens representing both sexes.
The species shows considerable variation, and a form which
I had intended to describe as a variety has the wings more
yellowish, the veins paler and the tip of each one very slightly
but distinctly darkened at the wing-margin, In the Indian
Museum are one male and three females from Sukna, 500 ft.,
1. vii. 08, Puri, Orissa, 22.x.08 (both Annandale), and Calcutta,
9. xii. 07. 1 took it at first for a.‘ plains” variety of my
supposed new species, but intermediate individuals connect it
with the typical form. Dr. Annandale says it rests with its
anterior legs stretched out flat in front and its hind legs behind.
The precise mathematical distinctions appertaining to the
bands on the legs, as given by Mr. Edwards do not hold good, as
they exhibit considerable variation. The ‘‘bristly hairs” men-
tioned in the above description are sometimes (especially those
on the neck, shoulders and pleure) sufficiently strong to be
termed real bristles.

Lechria, Skuse, Proc. Linn. Soc. N. S. Wales (2) iv, p. 830 (1890).
GunotyPs, L. singularis, Skuse ; by original designation.
“Two submarginal cells, the first very short, sub-triangular ;
four posterior cells ; no marginal cross-vein, but inner marginal
cell closed by first longitudinal vein, which ends at inner end of
first submarginal cell; small cross-vein situated some distance
before inner end of second submarginal cell; prefurca
originating beyond the middle of the wing; discal cell closed,
elongated, its inner half cuneate, and its inner end situated
before origin of preefurea ; wings glabrous. Antenne 16-jointed,
short. Feet long, slender ; tibize with spurs; ungues small,
smooth ; empodia. indistinct. Male forceps with two horny
appendages ; ; an outer linear one, and a longer somewhat hooked
inner appendage ; also five long, horny, needle-like processes of
the internal apparatus. Rostrum nearly half the length of the
head; palpi of moderate jiength, the first joint apparently
slightly the longest, the last three rather thicker, equal. The
antenne little longer (if any) than the head; joints of scapus
somewhat thick, subcylindrical, the first rather longer than the
second; flagellar joints subcylindrical, with very short hairs.
Eyes contiguous above, and almost so on the underside.
Collare inconspicuous. Legs clothed with only a microscopic
pubescence. Wings very cuneiformly narrowed towards the base,
with only a slight anal angle; covered with microscopic dots,
visible only under a high power; the veins at apical end of wings
densely beset with minute hairs; stigma narrow, elongate,
enveloping terminal portion of first longitudinal vein. The tip
of auxiliary vein is opposite the end of the prefurca and the
small cross-vein; the subcostal cross-vein at its tip; prefurca
very short, originating at an angle; the first longitudinal gently
arcuated into the second longitudinal, joining at the base of its
fork ; the first submarginal cell is very short ; the anterior branch
of the second longitudinal fork about half the length of the
posterior, the latter converges towards the tip of the third

longitudinal, and is equal in length to the petiole ; second sub-
marginal cell also with a short petiole; the small cross-vein
situated a little beyond middle of discal cell; the latter closed,
elongaied, its inner half cuneiformly narrowed, and its inner end
a little before the origin of prefurca; the great cross-vein a short
distance beyond inner end of discal cell ; fourth longitudinal vein
originating in fifth longitudinal at a little before one-third the
length of the wing, joined at its base to first longitudinal by a
short cross-vein; fifth, sixth, and seventh longitudinal veins
straight.
“The most striking peculiarities in the venation are, the course
of the first longitudinal which terminates in the second, the
absence of the marginal cross-vein, the first and second sub-
marginal cells being both petiolate, the position of the small
cross-vein, and lastly the shape and position of the discal cell.
. “This genus seems undoubtedly related to Gonomyia.’
(Skuse.)
Range. Australia and India.
The prefurca (that is, the basal section of the 2nd longitudinal
vein from its origin to its fork) is shown in Skuse’s own plate as
beginning just before the middle of the wing and not after it, as
he says in his description of the genus. It originates in my new
species at the same spot as in L. singularts, Skuse.
The auxiliary vein ends at the middle of the wing; the Ist
longitudinal vein extends to about three-fourths of the wing and
turns down, meeting the 2nd longitudinal at (singularis) or just
beyond (bengalensis) its fork, thus dividing the marginal cell- into
two parts. The 2nd vein begins a little before the middle of the
wing atarather wide angle, turning up rather angularly before
the middle of the prefurca, and forking ata little beyond its
entire length (bengalensis) or at two-thirds of its length (singu-
laris), the branches diverging at their tips. The upper submargina!
cell is subtriangular (singularis) or elongate-conical (bengalensis).
The 3rd vein originates at the angle in the preefurca and is nearly
straight, ending at about the wing-tip or just below it; the
anterior cross-vein placed distinctly before the origin of the 8rd,
of ordinary length, and over the middle of the discal cell, which
latter is elongate, about three times as long as broad, rather
irregular in shape with its inner end pointed. The 4th vein has
the upper branch forked, the lower prong with a rectangular basal
section which forms half the distal side of the discal cell, the
discal cross-vein forming the remaining half. The lower branch
of the 4th vein simple, slightly sinuous in both the known species;
the 5th, 6th and 7th veins nearly straight. Posterior cross-vein
just beyond base of discal cell (singularis) or a little before its
middle (bengalensis). Anal angle of wing somewhat rounded.

yellow hairs; belly concojorous, genitalia in both sexes small,
brownish yellow. Legs brownish yellow, thin and long; femora
with some stiff black hairs at the tip which, if viewed from
certain directions, give almost the appearance of two black spines ;
tibia unspurred. Wings clear yellowish grey, veins distinct.
Auxiliary vein ending just beyond middie of wing, the subcostal
cross-vein at its tip; the Ist longitudinal ending in the 2nd at
the point where this latter vein forks; the 2nd vein originating
at or just beyond the middle of the wing, at a sharp angle and
turning at one-fifth of its length suddenly upward, forking
beyond its middle, where it meets the tip of the Ist vein, the
upper branch shorter than the lower one; the 3rd vein issuing
from the 2nd at the angle in the prefurca, the anterior cross-vein
placed just before this point; the latter of moderate length,
placed over the middle of the discal cell, which is in the middle
of the wing, three times as long as broad, the proximal end
pointed, emitting three nearly parallel veins to the wing-margin ;
posterior cross-vein near base of discal cell; 5th, 6th, and 7th
veins nearly straight.

The venation of this genus is distinctly abnormal, the only
previously known species, LZ. singularis, Skuse,* comiag from
Australia. The 1st longitudinal vein ends in the 2nd at the
point where the latter forks widely, thus giving the appearance of
two long veins crossing one another at an angle of 45°, the point
of contact in singularis being punctiform, In my species the
point of contact appears almost as a small cross-vein.

Prof. Kertész places Lechria in the Ertoprerint, near Gonomyia,
to one species of which, G. incompleta, Brun., it bears a
remarkable resemblance in this part of the wing, and to which
genus, L. bengalensis, as a species at any rate, is eminently akin.
The only other possible interpretation of the wing, as figured
by Needham, would be to consider the 1st vein as angled towards
the tip and continuing to the wing-margin, meeting at the angle
the 2nd vein, which in this case would be simple, not forked, thus
making only one submarginal cell, which in its turn would
necessitate the genus, theoretically at least, being removed to
another section of this subfamily ; but its position near Gonomyza
seems hardly questionable.

* Describing a North-American species, Osten Sacken says of the male
organs “ more simple than that of the two species I have figured (b/anda and
cognatella), There are two lateral, elongated, subeylindrical (digitiform) lobes,
converging, but not lapping over each other in repose ; immediately above and
parallel to them is a single long horny style, the tip of which reaches beyond
the tip of the lobes; below the lobes, some small black horny organs are per-
ceptible.”
+ This .genus may be regarded as the centre one of a small group of genera
possessing the character of the peculiar forking of the 2nd longitudinal vein
making the short upper branch appear almost or quite like a cross-vein. These
genera are Empeda, Mongoma, Mongomivides, and Paramongoma.

vein, a little before or beyond it, the subcostal cross-vein placed at
its tip or near it; the 2nd vein beginning about the middle of the
wing, arcuated, sometimes considerably so, or nearly straight,
sometimes simple, but generally widely though shortly forked.*
The 1st submarginal cell very short, more or less triangular,
owing to the anterior branch of the 2nd vein being so much
shorter than usual, and so obliquely placed as to appear almost
like a cross-vein, this appearance being more conspicuous in some
species than in others ; its petiole long, and its inner end generally
beyond the tip of the 1st longitudinal vein, or nearly opposite it ;
yet in the commonest Oriental species it is considerably anterior
to this tip; marginal cross-vein absent; the 3rd vein with a very
short or quite moderately long basal section, varying with the
species, remaining portion nearly or quite straight ; anterior cross-
vein varying in length, placed a little forward or backward,
generally in a line with the base of the 3rd vein and the proximal
side of the discal cell. Discal cell open or closed; when open, it
coalesces with the 3rd posterior cell, which proves it is the
anterior branch of the 4th vein that is forked ; four posterior cells:
the Ist equal in length to, or shorter than, the 2nd submarginal
cell, varying in width with the species: the 2nd petiolate when
the discal cell is open, the petiole about as long as the cell; when
the diseal cell is closed, the 2nd and 3rd cells subequal, approxi-
mately normal in shape. Posterior cross-vein at some distance
before the proximal side of the discal cell, or in a line with it;
the 5th, 6th, and 7th longitudinal veins nearly straight.

Brazil, the Orient, and Australia.
In characterizing the genus Gonomyia, Mg., in his ‘ Monograph
of Norih American Trputrp®,’ Osten Sacken described the genus
as possessing two submarginal cells, noting, however, two examples
in which the anterior branch of the 2nd longitudinal vein being
absent, the Ist submarginal cell was obliterated ; and he expressed
his opinion that if other species occurred with this character, a
new genus might be founded on them. He, however, retained
the form provisionally in Gonomyia, emending in a footnote
(p. 178) his definition of the genus to warrant the inclusion of
species with one submarginal cell only.
In studying the question of the nomenclature of the veins in
the Gonomyva group, it will be seen that in this genus the 2nd
longitudinal vein may (in the case of my two species G. incompleta
and G. flavomarginata) be considered to be forked as usual, but
the 3rd vein would, under this theory, be absent, and the anomaly
of the anterior cross-vein joining the 2nd and 4th veins, instead of
the 3rd and 4th as usual, would be seen.
* In a North-American species (G. blanda, O. S.) it even forms a rectangle
at its base, with an appendix.
2H 2
ATO TIPULID A.
Of course, a different interpretation might be offered, namely,.
to consider the 2nd vein as being forked and the 8rd vein present, .
what I recognise as the anterior cross-vein being considered its.
basal section; in this case the 2nd vein would end at the tip of
the wing, the anterior cross-vein being obliterated, and the 3rd!
vein forming the whole upperside of the discal cell. But this.
interpretation would only cause more confusion in the identifi-
cation of the ramifications of the 4th vein.
A close study of the venation of Gonomyia, especially of the
4th longitudinal vein with its branches, convinces me that the
delineation of the veins as admitted in this work is correct. This.
is proved by such species as C. prowima and aperta, in which the
2nd longitudinal vein is forked, whilst the 8rd vein and the
anterior cross-vein are both present. In support of this may be
quoted Osten Sacken’s remarks in his elaborate ‘ Monograph on
the North-American TivuLip”®’: “ whenever the discal cell is.
open, it coalesces with the 3rd posterior cell, and thus it becomes
apparent that it is the anterior branch of the 4th longitudinal
vein which is forked”; to which he adds a footnote, “ Exceptions
are merely individual: thus I have seen a specimen of G. sub-
cinerea, the diseal cell of which was coalescent with the 2nd
posterior cell.”
Individual variation in this genus, it may be remarked,
rather common. Moreover, Osten Sacken (Ul. ¢. p. 178), nie
that the anterior branch of the 2nd vein was occasionally very
faint, and whilst his work was in the press, he discovered a new
species, G. manca, in which the 2nd longitudinal vein was simple,*
and he suggested that a new genus might reasonably be created
for it. Nevertheless, I refrain from doing so at present, as it 1s
evident that the genus Gonomyia forms a tolerably well circum-
scribed group of species, which it would be undesirable to dis-
member for each modification of venation.

that of G. incompleta; auxiliary vein not attaining middle of
wing; 3rd longitudinal vein with a much longer base than in that
species, and originating before the middle of the 2nd vein ; anterior
cross-vein shorter than in G. incompleta, so that there is not so
great a difference in width between the basal and distal ends of
the 1st posterior cell as there isin incompleta. Halteres yellowish,

Closely allied to Gonomyia, Mg., but differing from it in the
following particulars :—-
Marginal cross-vein present, but, owing to the shortness of the
anterior branch of the 2nd longitudinal vein, it is not this branch,
but the petiole of the Ist submarginal cell whicii the marginal
cross-vein connects with the Ist vein. ‘The cross-vein is thus
placed between the origin of the 3rd vein andthe fork of the 2nd,
nearer to the former than the latter. The auxiliary vein is longer,
extending distinctly beyond the base of the 2ud vein for some
distance, instead of ending about opposite that point, as in
Gonomyia. When the discal cell is open it coalesces with the
2nd posterior cell, not the 3rd, showing that it is the posterior
branch of the 4th vein that is forked, and not the anterior one, as
is the case in the preceding genus. The male genitalia are of
different construction.*
Range. Europe, North America, Greenland, Java, and India.
Although closely allied to Gonomyia, this genus should not be
difficult of identification, the most conspicuous characters being
its longer auxiliary vein, the presence of the marginal cross-
vein, and the forking of the posterior, not anterior, branch of the
4th vein.

dark, the joints narrow and elongated, practically bare except for
a single hair on each side of each joint. Thoraw: dorsum dark
mouse-grey, sometimes tinged with brown; a pale yellow line is in
some specimens rather conspicuous just below the grey colour of
the dorsum; sides of thorax brownish yellow: pleure a little
bluish, with microscopic grey dust. Scutellum rather bright
yellow, dorsum more or less darker : metanotum blackish. Abdo-
men: dorsum dark brown, a little paler on the belly ; short
sparse gold hairs dorsally and ventrally. Genitalia of the male
large and conspicuous, yellow, hairy, consisting of a pair of two-
jointed claspers and, apparently, two pairs of considerably smaller
ones. Ovipositor of the female normal, of moderate size, brownish
yellow. Legs brownish yellow, darker towards tips ; Coxe com-
paratively shorter than usual, the trochanters being longer than
usual, nearly as long as the coxe. Wings clear, iridesceut-

is, however, inadvisable to regard such minute differences as of generic value,
since the joints are found to show some degree of variation in many species in
this family. In my new species M. pallidiventris, the 2nd scapal joint is
nearly half as long as the Ist, in M. ¢enera all the flagellar joints are about

a little beyond the tip of the auxiliary ; the 2nd longitudinal vein
beginning at the first third of the wing, the prefurca being two-
thirds the length of the vein, the fork very wide, the upper branch
approximately at an angle of 45°, the lower branch ending just
above or below the wing-tip; marginal cross-vein very distinct,
oblique, leaning backwards, joining the Ist vein just before its
tip, and the 2nd vein just before it forks; the 3rd vein appearing
almost asa continuation of the first section of the 2nd vein, that
is to say, it emerges at the first third of the 2nd vein, losing itself
in the 4th longitudinal vein at the upper basal corner of the
discal cell; the anterior cross-vein is therefore absent. Upper and
lower branches of the 4th longitudinal both forked, the veinlets
parallel (pennipes) or gently diverging (fragillima). The Ist
posterior cell is absent, through the absence of the anterior cross-
vein, the uppermost of these cells is therefore the 2nd, which,
with the 4th, is pointed at the base (fragillima), or approxi-
mately rectangular (pennipes). Discal cell longer than broad,
hexagonal ; posterior cross-vein at or just before the base of the
discal cell, short; 5th vein bent suddenly downwards at its junc-
tion with the posterior cross-vein, until it meets the 6th vein
(which is nearly straight) before its tip, closing the anal cell;
7th vein very short, gently curved.*
Range. As restricted by me, the genus occurs in Tropical Africa,
Madagascar, Borneo, Philippine Islands, India and Ceylon.
Mr. Edwards resurrects Bigot’s genus Zrentepohlia to take the
place of Mongoma, but this genus cannot stand, being insufficiently
characterised ; in fact, its simple inclusion in a table with such
incongruous material as Diva (a separate family), Ptychoptera, and
Dolichopeza (the latter appearing a second time as Apetlesis), both
representing totally different subfamilies; with such genera as
Anisomera, Ula, Erioptera (as Octavia), each belonging to a dif-
ferent section of Limnopimn”, and finally with ‘“ Ligonevra”
(=Lygoneura, Mg., belonging to the Mycrropui1ip#!), is most
certainly no characterisation whatever. Moreover, the, nomi-
nation of a type species in itself does not, in my opinion,
constitute a generic diagnosis.
As WM. fragillimna, Westw., was the original type of Mongoma,
Westw., that species must of course remain the type of the
restricted Mongoma. Two other Oriental species belong here
also, tenera, Os. Sac., and pennipes, Os. Sac., the former from
the Philippines and India, the latter from Borneo, India, and
Ceylon.
Out of the material previously comprised in Westwood’s genus
Mongoma, I established recently + two additional genera, Pura-
mongoma and Mongomioides, based on well-defined and apparently

constant differences in venation. Paramongoma need not here be
discussed, since the only Oriental species is the P. albitarsis of
Doleschall, described many years ago from Java and apparently
never recognised since.
The other two may be easily separated as follows :—
Four posterior cells; * discal cell present ...... Mongoma, Westw.
Three posterior cells; discal cell absent ...... Mongomioides, Brun.
Mongoma (sensu lato) is highly interesting as presenting one of
the most conspicuous variations from the normal type of venation
inthis family. Previous to describing the genus Prof. Westwood
wrote to Osten Sacken for his opinion, and the latter’s reply is
indicative of its abnormality in his words: ‘The systematic posi-
tion of this species (IZ. fragillima) is very puzzling....” He
pointed out that the apparent resemblance between its venation
and that of Paratropeza, Sch.,t was only superficial and that it was
certainly a new genus.
Westwood’s figure of the original species, 1. fragillima, from
Central Africa, is excellent, and clearly portrays the distinctive
features of the genus; the long auxiliary vein ending only just
before the tip of the Ist longitudinal; the wide forking of the
2nd vein, which, with the marginal vein, gives a first impression
of the marginal cell being divided by two cross-veins into three
portions; the merging of the 3rd longitudinal vein in the 4th, at
the upper basal corner of the discal cell, thereby causing the
absence of the anterior cross-vein; the abrupt curve downwards of
the end of the 5th vein, closing, in most cases (speaking sensu
lato), the anal cell; the shortening of the two basal cells and the
very short 7th vein,—all characteristic features of this singular
genus.$
Eyen Osten Sacken, than whom no better authority on TrepuLIp&
* As regards the names of the posterior cells, if must be remembered that,
as the anterior cross-vein is wanting, the first posterior cell is absent, and that
the uppermost of the posterior cells, whether four or only three be present, is,
strictly speaking, the second and not the first. This view is confirmed by
Williston.
+ For description of Paratropeza see Verh. zool.-bot. Ges. Wien, xvi, p. 952
(1866).
+ This view is in accord with Williston’s opinion (Tr. Ent. Soc. 1896,
p. 292), but I only recently saw this author’s paper, long after I had studied
the question personally.
§ Of course, if the short vein joining the 2nd vein with the discal cell (or
the corresponding part of the 4th vein when the discal cell is absent) be con-
sidered the anterior cross-vein instead of the 3rd longitudinal vein, it follows
that there would be only one submarginal cell in any of the three genera
concerned, and the cell exterior to the anterior cross-vein will become the
Ist posterior cell. This would give Mongoma five posterior cells, and Mongo-
mioides and Paramongoma four posterior cells each. In support of this
suggestion it may be urged that the 3rd vein is not known elsewhere to ter-
minate in the interior of the wing. Personally I know of no case where it
does so, but it must be remembered that excessive abnormalities are not rare

is known, recognised the difficulty in allotting to the veins their
correct names (Berl. Ent. Zeits. xxvi, p. 90), and in describing
his first new species in the genus, MV. tenera, from the Philippine
Islands, he says in a footnote (referring to the words “the presence
of the two cross-veins inside the marginal cell” used in the text):
‘“* J call them cross-veins merely for shortness’ sake, because one
of fhem may also be considered as a branch of the 2nd vein.”
He spoke of the genus as representing ‘a form of venation which
is of very rare occurrence among Diptera, and we must suspend
our judgment on this point * until we have an opportunity of
seeing the insect from Java described by Doleschall.”’
At this time he was accepting three species as congeneric,
fragillima, Westw., allitarsis, Dol. (which latter it is evident from
the above quotation he had never seen), and his new species fenera.
In pointing out the difference of Doleschall’s species in having
only three posterior cells instead of four, as in fragillima and
tenera, it is obvious that he was guided by Doleschall’s figure
alone. The Dutch author’s remark ‘‘ two marginal cells ” does not
help in the question of terminology.

yellowish, the latter more or less darker. hora: in some speci-
mens three shining rather brownish thoracic stripes are distinctly
visible, the side ones much abbreviated in front, but continued

and dominant genus of Mycerropnitips, the anterior cross-vein invariably
takes a longitudinal position. To my thinking, however, the vein has every
appearance of the 3rd longitudinal vein by its imanner of origin, its superior
length to the usual anterior cross-vein, and the cell concerned has much more-
the appearance of a submarginal cell than of that of the 1st posterior cell.

concolorous to the tip. Genitalia of both sexes small. Legs
pale brownish yellow, the tibize becoming blackish on. the apical
half, but the actual tips are broadly snow-white, and the middle
pair have the snow-white portion thickened, much longer in
extent, and with a fringe of snow-white hairs on each side; tarsi
snow-white. Wings clear; halteres pale yellow.
Length 7-8 millim.
Redescribed from several specimens of both sexes in the Indian
Museum, with localities as follows :—Calcutta, 22.11. 10 (at light),

Type 3 in the Berlin Museum.
Apparently by no means an uncommon species in Calcutta
throughout a considerable part of the year.
The conspicuous snow-white thickening of the tips of the middle
tibiz easily differentiates this species from all others in this
group. It was originally described from the single type male
now in the Berlin Museum, taken at Tumbong Hiong, Borneo.
Apparently the female has not been noted before.

yellowish ; palpi dark brown; eyes separated by a narrow frons.
Antenne dark brown, with a little pale pubescence, if “ bent
backwards, they would reach a little beyond the root of the wings;
joints of the flagellum long, of nearly equal length, except the
first, which is a little longer; short-verticillate ” (Osten Sacken).
Thorax light brown or reddish brown, paler at the sides. Pro-
thorax well developed, prolonged into a short neck. Abdomen
darker brown, with pale pubescence, the tip blackish; belly yel-

Type. The location is uncertain ; originally in Osten Sacken’s
own collection.
Osten Sacken’s original description is incorporated with the
present redescription.
In the three examples herein described, there is a slight variation
from the original description of the species, as the base of the
3rd posterior cell is distinctly more proximal than that of the

2nd, and is pointed (as it isin JZ. fragillima, Westw., from Africa).
The bases of these two cells should be in a line according to the
author of the species. Again, in two of the present specimens
the posterior cross-vein is in a line with the base of the discal
cell, and occurs a little before it in the third, but this character is
known to be variable in the family, and there is little reason
to doubt the identity of the present form with Osten Sacken’s
species.

rather long, 2nd half as long, wider at tip; flagellum of fourteen
equal elongated dark brown joints; the whole antenne minutely
pubescent, each joint bearing a few long hairs. Neck shortly
conical, with a single transverse row of strong hairs. Thoraa:
dorsum dark mahogany-brown with a black middle stripe in front
of the suture; the post-sutural mesonotum divided by a wide
post-sutural yellowish depression; sides of thorax wholly yel-
lowish, also the scutellum, which is sometimes tinged with brown,
bearing a few hairs; dorsuin of metanotum dark brown, quite
bare. An irregular row of hairs on each side of the thoracic
dorsum, extending nearly to the suture; behind the suture a row
of longer bristly hairs on each side, also two fan-shaped sets of
hairs below the root of each wing. Abdomen brown, shortly
pubescent; blacker at base, and more or less on posterior borders
of segments ; tips yellowish. Belly uniformly livid yellow. Ovi-
positor yellow, rather long, slightly curved, apparently encased at
will in a sheath-like arrangement on the ventral side of the last
segment. Legs black, minutely pubescent; cox and trochanters
livid yellow; femora pale at base, with a few long hairs at tip,
hind pair with minute serrulation below at base ; tibiz whitish at

Differs from Mongoma by possessing only three posterior
cells instead of four, and by the discal cell being absent. It
agrees with Mongoma in the presence of the 3rd longitudinal vein,
and in the anal cell being closed at a greater or less distance
before the border.
482 TIPULID A.
The marginal cross-vein (in the four species known to me) is
more distal than in Monyoma; and the Ist section of the 2nd
longitudinal vein (.¢. that portion up to the origin of the 8rd
vein) is shorter than in Mongoma, being not longer than one-third
the length of that vein. Upper branch of 4th longitudinal vein
nearly straight, or gently curved ; posterior cross-vein distinctly
but not much before the fork of the 4th longitudinal vein. (‘This
may be found a variable character, when additional species are
discovered.) Remainder of venation and all other characters as
in Mongoma.*
Range. Sumatra, India, and Ceylon.
Bigot’s genus /rentepohlia is synonymous with Mongomiordes, but
was hopelessly uncharacterised (vide p.447), and it is to be regretted
that Dr. Enderlein has attempted to revive it. But for Bigot’s
mention of IV. irentepohlii as the type species, it would never have
been identified.

Types originally in Dr. Trentepohl’s and Wiedemann’s collec-
tions, presumably now in the Vienna Museum.
This species is likely to prove to have an extensive distribution
in the East, and is probably fairly common in Bengal and the
south-eastern parts of India. The clouded wing-tip makes it easily
recognisable from all other species in this group.
347. Mongomioides marmorata, sp. nov. (PI. IX, fig. 11.)
2. Head black ; eyes contiguous, face black ; proboscis, antenna,
and palpi yellowish ; back of head with few hairs. Thoraa yel-
lowish, practically bare; dorsum more orange, with traces of a
median dark line on anterior part. Scutellum and metanotum
apparently concolorous (damaged by pin). Abdomen yellowish
brown, dorsum with a tendency to dark marks; minutely pubescent.
Genitalia very large, yellow, hairy ; consisting of upper and lower
halves, the lower terminating in a sheath, the upper in a two-
bladed, rather short, stiff ovipositor. Zegs uniformly pale yellow.
Wings pale grey, with lighter spaces; the fore border shows four
such, of which the first reaches to the posterior border at the end
of the 7th vein; the second extends to the basal part of the mar-
ginal cell; the third reaches the submarginal cell; and the fourth,
a smaller one, is towards the end of the wing; the base of the
wing and the 8rd posterior cell are also nearly clear. Venation
as in trentepohlii, Wied. Halteres brown, stem pale yellow.

usual; the lower branch ending just above the wing-tip; the
short, upright marginal cross-vein joined to the 1st vem, where
it turns suddenly upward at its tip into the costa; prefurca
divided into about three equal sections, the origin of the 3rd vein
being at the end of the first section, the marginal cross-vein at the
end of the second; the 3rd vein emerging at a rather wide angle,
in a line with the basal section of the prefurca and for about as
long as that section, afterwards merged in the 4th longitudinal
vein at the upper basal corner of the 2nd posterior cell ; upper
branch of 4th vein forked at one-third of its length, the veinlets
parallel; the 4th vein forking a little beyond the origin of the
3rd vein; the basal side of the 2nd posterior cell rectangular ;
the lower branch of the 4th vein nearly in a line with the basal
section, the whole vein describing a gentle curve ; posterior cross-
vein situated just before fork of 4th vein, joing the 5th vein
(which is much fore-shortened) at the point where it suddenly
bends down and joins the 6th, thus closing the anal cell; the
short terminal portion of the 5th vein practically in a line with
the posterior cross-vein; the 6th vein quite straight, the 7th very
short, only one-third as long as the 6th, curved suddenly into the
margin of the wing. Halteres pale.

Genus PARAMONGOMA, Brun.
Paramongoma, Brunetti, Rec. Ind. Mus. vi, p. 295 (1911).
Mongomella, Enderlein, Zool, Jahr. xxxii, p. 61 (1912).
Gervoryen, Cylindrotoma albitarsis, Dol.; by present designation.
This genus differs from Mongoma, Westw., also in the venation
only ; principally by the punctiform contact of the 2nd longitudinal
vein with the discal cell, thus obliterating the 3rd vein. The
discal cell emits only three veins, for arguing from analogy and
comparing the wing with that of Mongoma, it should be the anterior
branch of the 4th longitudinal vein that is forked, thus making
only three posterior cells, of which the 1st and 2nd are of equal
length, and with pointed bases. The anal cell is open somewhat
narrowly but distinctly.
Range. Java.
The only Eastern species that at present is referable to this
genus is P. albitarsis, Dol. (Nat. Tijds. Ned. Ind. xiv, p. 391, pl. iv,
fig. 1), which has not yet been found in British India, being
originally described from Java, and apparently not having been
seen since.
Doleschall’s figure is rather carelessly drawn, as the 1st longi-
tudinal vein is shown emerging from the auxiliary vein near its
tip; the 2nd vein is straight after the bend, which takes place at
PARAMONGOMA.—-SYMPLECTA. 485
the exact corner of the discal cell, there being neither 3rd longi-
tudinal vein nor anterior cross-vein. There are only three posterior
cells, of which the first two are subequal, with obtuse-pointed
bases; the posterior cross-vein is a little beyond the base of the
discal cell, which is about twice as long as broad. ‘The anal cell
is open; apart from this, the 5th and 6th veins bear the same
relation to each other as in Mongoma. The 7th vein is not
shown, perhaps owing to the full insect being illustrated, with
the wings rather close to the body; in this position the 7th vein
would be easily obscured by the proximity of the wing to the
abdomen.
As P, albitarsis, Dol., will probably be found to occur in South
India or Ceylon, and has been made the type of a new genus, it is.
advisable to append a briet description of it.
The species is greyish brown in colour, with -short pubes-
cence ; head globular: eyes large, black, kidney-shaped ; proboscis
moderately long. Flagellum of antennz of fourteen subequal
cylindrical joints becoming smaller towards the tip of the antenne.
Abdomen narrow, tip pointed and black. Legs very long, tarsi
snow-white. Doleschall speaks of only two posterior cells, but
this is only due to a different method of naming them. Found
on warm damp days dancing in the air. I have not seen the
species myself.
But for the difference in venation it must be very like Mongoma
pennipes, Os. Sac., but the conspicuously thickened tips of the
white middle tarsi will at once distinguish the latter species.
Mongomella, End., is an absolute synonym of Paramongoma.

without spurs, ungues small, empodia distinct. Wings glabrous,
also the veins. Two submarginal cells, four posterior cells, and a
discal cell. Auxiliary vein long, ending some distance before the
tip of the 1st longitudinal ; 2nd vein beginning before the middle
of the wing and some distance anterior to the subcostal cross-vein,
forking about opposite the tip of the auxiliary vein, the sub-
marginal cross-vein being opposite the latter point; the preefurca
a little less than half the full length of the vein; the 3rd vein
originating just before the fork of the 2nd vein, close to the
anterior cross-vein, which is at the pointed proximal corner of
the discal cell; the latter being subtriangular and as long as, or
slightly shorter than, the 2nd and 38rd posterior cells; posterior
cross-vein distinctly before the fork of the 4th longitudinal ;
5th and 6th veins nearly straight; 7th vein conspicuously
bisinuate.
Range. Himalayas, Persia, Europe, and North America.
Near T'rimicra, Os. Sac., but that genus differs from Symplecta
‘by the last joints of the antenne being suddenly and conspicuously
reduced in size; moreover, in Trimicra the 2nd longitudinal vein
issues from the 1st at an acute angle, not in a gentle curve; and
the 7th vein is straight. The basal part of the male genitalia is
more thickened in Z’rimiecra.
Helobia, St. Farg. (1825), antedates Symplecta and is synonymous
with it, but has not been adopted, the reason not being known to
the present author. It does not appear to be preoccupied.

GENOTYPE, G. tristissima, Os. Sac., his second species ; by
designation of Coquillett (1910).
Head: eyes glabrous, nearly contiguous below, but separated
above by a broad convex frons. Proboscis short ; palpi moderate
in size, terminal joint longer. Antenne 16-jointed, reaching
backwards to the root of the wing in both sexes; Ist scapal joint
long and cylindrical, 2nd always much shorter, of varying width
according to the species; flagellum of elongate subcylindrical
joints, shorter in some species and more globose, the length of the
verticillate hairs varying with the species. Thorax prolonged
anteriorly, or shorter, according to the species; suture distinct.
Abdomen normally elongate, linear, subcylindrical. Genitalia of
male consisting of claspers, in which the first joint is much more
slender than in G'onomyia, the 2nd (horny) joint being in some
species almost linear and pointed; a second pair of horny appen-
dages below the first, shorter and stouter. In the female the
ovipositor is peculiarly formed, the upper valves being incrassated
and arcuate on the lower side towards the base, the lower pair
being very short, about half the length of the upper ones, the
whole ovipositor having thus rather an unusual appearance.
Legs long and slender, microscopically pubescent ; tibie without
spurs; empodia distinct; middle pair of legs rather shorter than
the others. Wings normally glabrous.* Two submarginal cells,
four posterior cells ; discal cell open or closed. The auxiliary
vein ending at a good distance beyond the origin of the 2nd vein,
with the subcostal cross-vein a little more or less distant from its
tip. The 2nd longitudinal begins about the middle of the wing,
forming a moderate angle, the prefurea, which often turns abruptly
upward just beyond its middle, generally about half the length of

the inner end of the 1st submarginal cell, or at about the middle
of it, occasionally exactly at the fork of the 2nd vein, and, in rare
cases, absent altogether;* the 3rd vein generally originating
from the angle in the prefurca, being almost (apparently) a con-
tinuation of the basal section of the prefurca, and curved down-
wards towards its tip; 7 the anterior cross-vein immediately
beyond the origin of the 3rd vein, moderately long, joining the upper
basal corner of the discal cell, which latter is oblong, with pointed
ends, the posterior cross-vein being situated before the middle
of it; the 5th, 6th, and 7th veins gently curved towards their tips.

* The marginal cross-vein is very inconstant, even in the same species,
both as regards its exact position and its presence or absence, as Osten Sacken
mentions a German species of which many specimens were seen by him without
it, although normally it should have been present in that species. In this
species, too, the abdomen is more clubbed at the tip, and the genitalia are of
different construction. He also possessed another species, from Italy, in
which there was no marginal vein at all, and the discal cell was open, being
coalescent with the 3rd posterior cell. This species he thought might be
Erioptera lateralis, Mcq., but it is to be noted that in Prof. Kertész’s recent
«Catalogue of Diptera’ dateralis is referred to Gonomyia. It is, of course,
possible that Osten Sacken’s identification of the species was erroneous.
The fact that the marginal vein is occasionally absent in this genus may be
considered likely to cause confusion between it and Gonomyta, the species
having considerable resemblance to one another, but in the present genus the
branches of the 2nd longitudinal vein (which is always forked) are much too
approximately parallel to be readily confounded with the very widely opened
fork of Gonomyia.
{+ Exceptions occur; for instance, in G. flavomarginata, Brun., a compara-
tively long basal rectangular section is present.

distinctive character is available. Such exceptions must be allowed for in
