A Revision of the Asilidse of Australasia./
By Gertrude Ricardo.
'II
In a collection of Diptera sent me several j^ears ago by-
Mr. French from the Melbourne Museum, for determination,
were a certain number of Asilidse. In attempting to name
them I found great confusion in the nomenclature of the
species, and of their generic place, from Australia. The
following paper is an attempt to clear up some of these
errors, but no doubt there will still be much to revise when
more material is available. The majority of the old species
were described by Macquart and Walker, who both worked
at about the same time — Walker from 1849-1856 and
Macquart from 1838-1855 ; iu consequence there are very
474 Miss G. RicaiJo — A Revision of
many synonyms between these two authors. Since then a
few species have been described by Schiner and Thompson,
and a few older ones were described by Wiedemann and
Fabricius.
Most of Macquart^s species have been seen by me in the
Paris Museum through the kindness of M. Bouvier, and in
especial of M. Surcouf, and compared with Wall^er's species
in the Brit. Mus. Coll.
The pagination here used for Macquart's Dipt. Exot. is
that of the original work, first published in Mem. Sci. Agri.
et Arts de Lille, 1838-1855 ; the one usually used is unfor-
tunately that of the reprint, which did not retain the original
pagination. Priority is given to Macquart^s names over
those of Walker as a rule, as the descriptions appear the
best. Williston and Hine are f'dlowed in placing the genus
Leptogasier in a separate subfamily and in the arrangement
of the subgenera of Asilus.
The species from Australia, New Zealand, and Tasmania
only, are described; those from other parts of the Australasian
Region are, as a rule, merely given with their references.
Judging from Walker's species, not many of the species of
the continent extend beyond it.
All types are in the British Museum Coll. unless otherwise
specified.

AValker's type a male from New South Wales.
In Brit. Mus. Coll. are females and a male from Burpen-
gary, S. Queensland [T. L. Bancroft), 1904.
A small species, with clear wings, yellowish legs, thorax
and abdomen black.
Length 9-10 mm.
In Macqi;art^s type the legs are somewhat darker than in
those of Walker's type. The first two joints of the antenna in
Macquart's type are reddish, not black as stated, and tin;
small transverse vein of the wine/ is in the middle of the discal
cell, not very near the base as shown in figure.
Macquart's description is as follows : —
Length 5 lines. (^ .
Palpi with white hairs. Beard and moustache white ;
face with yellowish tomentum. Forehead brown. Antennge :
the first two joints black (in reality reddish), the third
wanting. Abdomen : anterior and posterior borders of
segments ashy grey. Legs fawn-coloured, with coxae grey ;
some black colour on the anterior and middle legs ; poste-
rior legs wanting. Wings clear. From Tasmania.
To this the following particulars may be added : — Thorax
greyish, with three black short stripes. Knees of tegs nar-
rowly black, apices of tarsi also black ; bristles on the last
four tarsi and on the apex of the first hind tarsus black,
elsewhere pale yellowish. The small cross-vein of the iving
is at or slightly below the middle of discal cell and the fourth
posterior cell is pedunculated at its base ; the cross-vein
closing the second basal cell joins the pedunculated part at
about the middle. The wings are shorter than the body,
measuring 5-6 mm.
Leptogaster antipoda, Bigot.
From Tasmania.
Described as having testaceous legs, the posterior femora
widely brown at base, with another narrower brown band
before the apex.
Leptogaster bancrofti, (^ ? , sp. n.
Tvpe ((J) from Mr. French's Coll., Victoria (1898).
Type ( ? ) from Queensland (1909) {Dr. Bancroft).
A black species with yellowish legs, but the hind legs
darker, almost wholly black. Wings clear, the small cross-
vein at the middle of discal cell, and the cross-vein closing
second basal cell also joining the stalk of fourth posterior
cell at about the middle. Length 12 lum. ; wings 6-7 mm.
Face covered with' greyish tomentum, the moustache yellow.
Anten?ice black. Fore//ecf/ the same as face. Thorax red(\\>h

bro\vu or reddisli grey, with a medium and lateral black
stripes, sides of thorax ashy grey. Abdomen black, with well-
marked grey segmentations. Legs reddish yellow, the knees
of fore legs and joints of tarsi black ; the posterior femora
blackish on apical half, the extreme apex red ; the posterior
tibiae almost wholly blackish ; the first joint of hind tarsi
pale yellow, black at its apex, and the other joints chiefly
black ; bristles of tarsi black, except on the first joint, where
they are yellowish.
Leptogaster australis, ^ , sp. n.
Type ( c? ) and another from Townsville, Queensland
(F. Dodcl), 1903.
A species distinguished from L. geniculatus, Macq., by its
larger size, by the reddish-brown thorax with one median
black stripe, and by the cross-vein closing the second basal
cell joining the peduncle of the fourth posterior cell at two-
thirds of its length.
Length 14 mm.
Face covered with silvery-grey tomentum, the scanty
moustache pale yellow. Anlennce black, the first two joints
reddish. Forehead yellowish above the antennae, black at
the vertex. Thorax reddish brown, with greyish tomentum
on dorsum, bordering the black stripe, which does not reach
the posterior border ; sides covered with yellowish tomentum,
breast reddish brown ; scutellum same colour as thorax.
Abdomen obscurely yellow, covered with grey tomentum ; the
last three segments blackish, with very fine whitish pubes-
cence ; genitalia reddish ; underside blackish. Legs reddisli
yellow, the first joint of the tarsi paler, almost white, the
remaining joints reddish brown; knees black and the ajjical
two-thirds of the hind tibice are reddish brown ; tibiai with
scattered white bristles ; pubescence on legs very slight, most
noticeable on the hind pair, where it is almost wholly white ;
coxae reddish brown, with white tomentum. Wings hyaline,
tinged with brown on the basal half; this is hardly notice-
able in the second male ; all cells open ; the cross-vein at or
beyond the middle of discal cell. Halteres yellow.
J^eptog aster dissimilis, ? , sp. n.
Type ( $ ) and another from Stannary Hills, N. Queens-
land, about 3000 feet {Dr. T. L. Bancroft), 1909 ; and another
female from Queensland from the same collector.
A handsome species, distinguished by the reddish-yellow
legs marked with black on the knees, and with the apical
half of the club-shaped hind femora deep black ; the apices
of tibiae, the hind j)air widely, black.
the AsilicIiK of Australasia. All
Length 16 mm.
Face greyish yellow, the scanty moustache pale yellow.
Atitenna black, the second joint reddish. Forehead darker
than face. Thorax reddish brown, blackish in the centre,
sides with yellowish tomentum. Abdomen blackish, the first
four joints almost wholly reddish yellow, in the other female
not so distinctly so, only the first two joints being dull
yellowish. Legs reddish yellow ; the knees, apical half of
hind femora, apices of tibiae, and all the tarsi except the first
joint black. Wings tinged yellow at base, the small cross-
vein about the middle of discal cell, the cross-vein closing
the second basal cell joins the stalk of fourth posterior cell
at two-thirds of its length.
This species is distinguished from Leptogaster bancrofti
by its larger size, the yellow base of abdomen, the yellow
tomentum on sides of thorax, the posterior tibiae less widely
black, and by the situation of the cross-vein closing second
basal cell.
The following species are recorded from other parts of the
Australian Region : —

This genus was formed by Walker for one species from
Tasmania, Cabasa rufithorax, which he later stated was a
variety of Dasypogon pulchellus, Macq. ; the second species
1 rom the same locality, which he named Dasypogon venno,
had likewise been described previously by Macquart under
Oasypogon.
Tlie genus is allied to Brachyrrhopola, but easily distin-
guished by the humpbacked thorax. Schiner did not include
it in his table. Walker omitted any mention of the presence
of the curved spine on fore tibiae, which is very distinct in
the known species, which are small, the thorax bright-
coloured, the abdomen blackish, the wings brownish. The
antenuae long, the third joint nearly twice as long as the
tirst two together.
The species as yet recorded in the genus are four, only
the first two being from Tasmania, the others from Batchian
and Aru Island.

Macquart's type (c?) seen in Paris Museum, 12.4. 11.
W alker's type is identical with it.
AValker's type ( (^ or ? ?) from Van Diemen's Land.
The species is only distinguished from Cabasa pulchella
by the wings, which are brown on the basal half only as far
as the apex of the discal cell, and is rather smaller in size.
Macquart's description is as follows : —
Length 3 lines, J . Face and forehead black, with grey
tomentum ; moustache plain, yellowish. Antennae: the
first two joints black, the third is wanting. Thorax shining
red, with a dorsal band and its posterior border blackish

shining black, with faint green reflections. Legs black,
almost naked ; posterior tibiae swollen at apex. Halteres
fawn-coloured, large, becoming wider from base to apex.

hyaline; neuration normal.
From Tasmania.
Cabasa glabruta, J , Walker.
Type ( ^ ) from Batchian.
This type and the following one W^alker failed to recognize
as belonging to the above genus created by himself.
It diti'ers from C. rubritliorax and C. pulchella by its

Distinguished by the colouring of the legs from the other
species. Legs black, the coxse, the extreme apices of femora,
and tiietibise (with the exception of the apices) reddish yellow.
Antenna black. Thorax black, but covered with brownish-
yellow tomentum ; breast-sides the same, with a broad
shining reddish-yellow stripe. Abdomen blue-black, with
narrow testaceous posterior borders.
Chrysopogon, Koder.
Berlin, ent. Zeit. xxv. p. 213 (1881) ; id., Stett. ent. Zeit. liii. p. 243
(1892).
Founded for C. crabroniform.is, Roder ; C. milUeri, Roder,
was added in 1892. The author distinguishes the genus
from Laparus, Loew (now Neolaj^arus), by the stout spine
on each side of the thorax and by the closed or very much
narrowed first posterior cell ; this last distinction will not
hold good, as two of the species now added to this genus
both have the cell open, but possess the stout spine on the
thorax which will serve to divide the genus from Neolaparus.

Abdomen the same width throughout ; the first segment and
anterior border of second blacky shining ; the third with an
isosceles triangular black spot at each side, the apices ex-
tending nearly to the middle of the segment along the
])Osterior border; on the fourth there is a similar but ill-
defined smaller spot in the female type, in the males the
sides of the fourth and fifth segments are narrowly black,
])ubescence on dorsum chiefly fnivous, on the sides of abdo-
men black; underside wholly black; ovipositor of female
short, fulvous ; genital organs of male small, almost hidden,
fulvous. Legs same colour as greater part of abdomen, the
coxae and femora sliining black, with black pubescence.
Wings yellowish, with yellow veins tinged with grey at apex
and on inner border, all posterior cells except the first
widely open, the anal cell open, but very narrow, at border,
small transverse vein just beyond the middle of discal cell.
Halteres yellowish.
The antennce in this species and in C. queenslandi have the
small style on the lower border of the third joint, and the
upper border is excised and armed with a small spine. In
the other species the end of joint seems broken off. Pro-
bably this characteristic will prove generic ; the genus,
however, is easily distinguished by the spine on thorax.
Brachyrrhopola, Macquart.
Dipt. Exot. Suppl. ii. p. 51 (1847).
This genus was formed by Macquart for his species
B. ruficorms, from Tasmania, to which, later, a second species
was added by Roder, originally named by Macquart Dasy-
pogon maculinervis ; and Professor Roder added two new
species, one of which, however, is a synonym of a species
erroneously placed by Macquart under Codida, Avho also
had described one species earlier under Dasypogon which
belongs to this genus.
The genus belongs to the group with a curved spine at
end of fore tibiae, and is characterized by the club-shaped
abdomen and the wings with all posterior cells and the anal
cell open. Antenna hardly the length of head as Macquart
states ; the first joint a little long, the second short, the
third three times as long as the first joint, nearly straight
above, a little convex below, and attenuated at the base :

Dioctria tasmanice, Walker.
Type of B. limbipennis, ? , Macq,, seeu in Paris Museum,
12, 4. 11, is a naale, not a female as on label and in de-
scription, identical with a specimen of D. tasmanice, and
comes from Tasmania.
The type of B. maculinervis, described as a mutilated
headless female, appears from the description and the figure
of the wing to be idetitioal with Macquart's earlier species.
In Brit. Mus. Coll. : type of D. tasmanice, a male, from
Tasmania, and a male and female from Melbourne (French) ;
others from Burpengary, S. Queensland {Dr. T. L. Bancroft),
•488 A Bevii>ion of the Asilidoe of Australasia.
and from Hobart {J. J. Walker). lu Mr. French's coll.
specimens from Victoria.
A species easily recognized by the dark colouring on fore
border of wing. Eeddish brown, with two yellowish narrow
segmentations on abdomen.
Type (c?) 12 mm. Bigot gives 18-21 mm. for B. maculi-
nervis. Specimens range from 12-20 ram.
Face covered with greyish or yellowish tomeutum, and
with two black shining stripes starting together from below
the antenna? and becoming broader and separated below.
Moustache of many weak white bristles continued up the
face as whitish hairs. Palpi large, red, with many black
bristly hairs. Antenna red, the first two joints with black
hairs ; the third about twice as long as the first two
togetiier, with a distinct style. Forehead black, shining,
with numerous long white hairs. Thorax reddish, black on
dorsum, with scanty white pubescence, sides reddish, black
anteriorly, with three greyish or yellowish tomentose stripes,
one on the prothorax and the others above the second and
third pairs of legs. Scutellum reddish. Abdomen reddish,
shining, somewhat darker at base, the third and fourth seg-
raentj' with very narrow pale yellow posterior borders ; hairs
at sides whitish, and a little pubescence of the same colour
on dorsum. Genital organs in male prominent, with long
white pubescence ; in the female the ovipositor small, ending
in a circlet of spines. Legs the same colour as abdomen,
the tibiae at base bright yellow, femora largely black below,
bristles black. Wings large, hyaline, with deep brown
colouring on the fore border, extending from the base to
the apex, filling the first broad cell and the base of the
second one, reaching across the base of it and of discal and
fourth posterior cells, then bordered by the third longi-
tudinal vein till it reaches the fork, where it spreads slightly
beyond the posterior vein of fork, leaving the apex of second
submarginal cell clear.
This description is chiefly taken from Walker's type and
from the specimen identified with D. linibipenais, both males,
together with a female from Melbourne.
Same of the other specimens vary in the following parti-
culars, but appear to be the same species, none of tbeni
varying in the extent of colouring of the wing : — The/cce is
black in the centre or reddish. Moustache black. Only
the posterior tibiae are yellow at base, or none are yellow,
the knees above representing this colour. The yellow seg-
mentations on abdomen are absent.

entering the base of fourth and fifth posterior cells ; the
first basal cell is almost wholly and the second one partly
hyaline.
BrachyrrJiO]3ola fenestrata, Macq.
Bradiurrhopola victorice, Ruder.
In Brit. Mus. Coll. a female from Victoria {French Coll.).
The species was described by Macquart under his new
genus Codula, with the type of the genus, viz. Codula limbi-
pennis; but it is no doubt a species of Brachyrrhopola, a
the Asilidse of Australasia. 587

Brachyrrhopola fulva, ? , sp. n.
Type ( $ ) and another from Mackay, Queensland (G.
Turner) .
A small species, the wings identical with those of B. fenes-
trata, but easily distinguished from it by the yellowish
abdomen, with the base and last segments more or less
blackish ; face golden yellow ; the thorax with stripes and
short golden pubescence.
Length 9^ mm.
Face black in centre, shining, sides covered with golden
tomentum; moustache yellow, the hairs paler at tips; palpi
black w^ith black hairs, scanty black hairs below and round
head. Antenna reddish yellow; first two joints stout, almost
equal in length, the third long ; the antennse longer than the
depth of head. Thorax blackish brown, with three median
brown stripes shining through the yellow tomentum and
pubescence, which is most apparent on the shoulders and
anteriorly; sides of thorax and head black, with two golden-
haired stripes ; some long yellow hairs on thorax posteriorly ;
scutellum reddish. Abdmnen reddish yellow ; the first seg-
ment and anterior border of second black, remainder of
second segment and the third shining yellowish, almost bare ;
the fourth, fifth, and sixth segments black on anterior
borders, the last band the narrowest; the last three segments
with short golden pubescence on the yellow part, the same
pubescence appears but very sparsely on the other segments ;
the abdomen is club-shaped, the first two segments being
narrower, the others convex ; underside concave, blackish,
yellow at base. Legs reddish yellow ; coxse, base of femora,
and apices of anterior and posterior tibiae and fore tarsi

cell; the basal cells and discal cell almost entirely and the
first posterior cell on its basal half hyaline; the small trans-
verse vein below the middle of the discal cell. Halteres
yellow.
This species is very probably identical with Codula quadri-
cincta, Bigot, but without seeing the type it is impossible
to decide.

592 Miss G. Ricardo — A Revision of
Macquart^s type was recorded from New South Wales,
and he notes another specimen as from Brazil.
Macquart^s type (?) and three other female specimens,
all varying in size, were seen by me in the Paris Museum.
In the type the third segment is almost wholly dark, in the
other specimens only dark on the anterior border as in the
specimens in the British Museum. Apex of abdomen
furnished with circlet of spines.
Walker's three types were described from unknown
localities.
There are specimens in the Brit. Mus. Coll. from Aus-
tralia, New South Wales. Mr. Froggatt records a specimen
from Mittagong, New South Wales.
This species cannot belong to Neolaparus, owing to the
different formation of the moustache and the absence of
antennal style. It is distinguished from the other two
species placed in this genus by the more open fourth poste-
rior cell, the last part of its upper vein not turning sharply
downwards, and the first vein from the discal cell does not
bulge into the first posterior cell. It varies in size greatly,
judging from the specimens in the British Museum Coll.,
which measure from 22-25 mm. (males), 15-22 (females).
The moustache is composed of stout bristles. The antennce
are reddish yellow ; the first two joints with yellowish hairs
and some bristles ; the third bare, cylindrical, in one male
nearly three times as long, in two females only twice as long
as the first two joints together. The bristles at sides of
thorax'are rather short and yellow, the scutellum apparently
devoid of them.
Neosaropogon salinator, Walker.
Type ( ? ) and another female from Port Essington,
N. Australia, and a male and female from Port Darwin,
N. Australia [Buckland).
Distinguished from Neosaropogon claripennis, sp. n., by
the shorter, more club-shapect third antennal joint, by the

This genus has been as yet confined to the American
continent, but the species described below appears to belong
to the genus, which is distinguished by the closed fourth
posterior cell of wing before it reaches the margin, by the
absence of a style to antennse, by the comparatively long
first two joints of antennae, and l)y the wide head. The face
has no tubercle and the moustache is almost confined to the
oral opening. My new genus Neosaropogon is distinguished
from it by the fourth posterior cell of wing being open or
only narrower at border.

Hutton's co-type is at or beloio the middle of discal cell and
is clouded with brown, fore border tinged brown, not ex-
tending beyond the first submarginal cell. Abdomen more
blue-black, with the white tomentose spots at side more
apparent.

A small, slender, reddish species, with a general resem-
blance to a Leptogaster species.
Length 11 mm.
Face covered with golden-yellow tomentum. Moustache
of pale yellow bristles. Palpi ferruginous, with yellowish

short, armed with very stout short spines on outer border,
and on inner border with thick hairs.
CoDULA, Macquart.

This genus, formed by the author for C limbipennis from

which his second species of Codula belongs, but it is at once
distinguished by the absence of the curved spine on fore
tibiae, the moustache is composed of fewer hairs and con-
fined to the oral opening, and the abdomen is stouter and
shorter. With Macquart^s second species and one placed
by Bigot in this genus transferred to Brachyrrhopola, only
Macquart's typical species and one nearly allied to it remain
in the genus.

the Asilidte of Australasia. 151
Bathypogon, Loew.
Progr. Realscliule, Meseritz, 1851, p. 13 (1851).
This genus was formed by Loew for his species B. asili-
formis from Australia, and Sehiuer added B. hrachypterus,
Macq., besides other species from Chili.
The genus belongs to the group of DasypogoninxB with no
spine on fore tibise and is distinguished by the rather short
wings with the fourth posterior cell closed and the first
widely open, the vein closing the fourth posterior cell is
nearly on a line with the one closing the discal cell; the
face has a distinct tubercle, with the moustache reaching the
antennae, which have a style-like bristle on the end of the
third joint. It appears to be distinguished from Stenopogon
by the broader face.
The statement in Schiner's table that the wings in this
genus in proportion are long and narrow, is somewhat mis-
leading, so far as concerns its relationship to the other
Australian genera of Dasypogonince, from which it is clearly
distinguislied by the rather short narrow wings, often not
reaching far beyond half the length of the abdomen.
The following described and one new species, all from
Australia, now belong to this genus.
The differences between some of the species are very small
and probably with the advent of fresh material some will
hardly be maintained as distinct.

black above, then yellow. In the specimens before me there
are no black hairs on upper part of moustache. The small
cross-vein of wing is situated slightly beyond the middle of
the discal cell.
Length of specimens 18-20 mm.
Walker's type is probably a specimen of this species; the
type is in very bad preservation.

Bathypogon aoi'is, Walker.
Bathypof/on nsiliformis, Loew.
? Asilus iniitillatus, Walker.
Type female from Adelaide (Ent. Club), other, females and
males from Mackaj^, Queensland (G. Turner) (1894)^ and
Barpengary, Queensland [Dr. T. L. Bancroft), 1904.
Distinguished from Bathypogon brachypterus by the
■wholly blackish femora, and by the blackish tibiae^ bristles
on legs chiefly yellowish, the small cross-vein of wing is
situated about the middle of the discal cell;
Two of the females and one male from Queensland have
the femora largely reddish as in B. brachypterus, but the
tibiae remain blackish ; perhaps eventually the two species
may be merged in one.
Length 17-26 mm.
The type of Asilus muiillatus, Walker, from Australia,
abdomen missing, is evidently a species of this genus,
apparently similar to B. aoris, with the exception of the
small cross-vein of wing, which is distinctly below the
middle of the discal cell.
Loew suggested that his species B. asiliformis might be
identical with Dasypogon plumbeus, Fabr. (Ent. Syst. iv.
p. 382; id. Syst. Antl. p. 165 ; Wiedem. Ausszweifl. Ins. i.
p. 413 [^AsilusA^ ; see Kertesz's Cat. for further refs.), but that
the description of this last is too poor to serve for recognition
of the species, and further concluded Dasypogon bocbius,
Walker (List Dipt. ii. p. 333), placed in the same group as
Dasypogon plumbeus by Walker, might be identical ; tbis last
type is apparently destroyed, not being in the Brit. Mus.
Coll. From Loew^s description his species is evidently
identical with B. aoris. The Fabrician and Walker species
might well be deleted from list.
Bathypogon pedanus, Walker.
Type ( ? ) and another from Swan River, W. Australia
(Ent. Club) .
Distinguished from B. brachypterus by the wholly black
femora, and from B. aoris by the pale reddish tibiae ; the
posterior pair are darker. Thorax black, with very distinct
whitish-grey sides ; shoulders red.
Length 18 mm.
Bathypogon testaceovittatus, Macq., said by him to be
154 ]\liss G. Ilicardo — A Bevision of
allied to Bathypogon aoris, Walker, was placed by Bigot in
this genus, probably correctly, judging from the figure of
ivhu/ given by Maequart ; it is described by him as having
the sides of thorax and abdomen testaceous. If the figure of
the ivinff is correct this species is distinguished by the
rounded angle of the anterior branch of the fourth vein
emitted from the discal cell.
Bathypogon maculipes, Bigot, from Australia, measuring
22 mm., is desci'ibed as having the anterior and intermediate
femora black, but reddish in the middle, and the posterior
pair with an elongated reddish spot. The anterior tibiae
with a similar smaller reddish spot, the bristles of tibiae
whitish.
Neither of these species is known to me.
Bathgpogon nigrinus, sp. n.
Type ( cJ ) and a series of males and one female from
Burpengary, S. Queensland [Dr. T. L. Bancroft).
A, species very similar to B. bracJiypterus, Macq., but
distinguished by the black (not yellow) bristles on the legs
(yellow bristles are only present on the fore tarsi) and by
the paler indistinct red of the fore tibire, which are covered
with short white pubescence, and by the first two joints of
antenncB being red, not black.
Length 16-18 mm.
Face reddish, with some little grey tomentum, at the sides
of the face and below the antennae appearing grey, being
covered with a silvery white and grey tomentum ; the
tubercle large, taking up most of the face ; moustache
reaching its whole length, formed of strong black bristles,
with a few white ones below. Palpi black, with yellowish-
white hairs. Beard white. Antemiae black ; the first two
joints red, with yellowish-white long hairs; the first joint
twice the length of the second, the third broad, with a style-
like ending. Forehead black, with yellowish-grey tomentum,
which is silvery- white above anteniicC ; pubescence of black
hairs, at vertex very stout, black, spine-like bristles ; round
head white hairs. Thorax brownish, with two median
and side black stripes, posteriorly covered with silvery-
grey tomentum, which also covers the sides. Scutellum
black, bordered with same-coloured tomentum and with
black bristles. Sides of thorax with long black bristles.
Abdomen black, covered with short white hairs and with
black bristles at the segmentations ; sides "covered with grey

tomentum ; underside blaclvish. Legs armed with bristles,
■which are black, on the fore tarsi some yellow ones ; coxse
red, with white tomentum and long white hairs and one
black bristle below; femora black above, with white pubes-
cence, below red, with long white hairs ; tibise yellowish red
on the outside, black on the inside, with white pubescence ;
underside of fore tarsi with yellow pubescence ; tarsi reddish,
covered with white pubescence. Wings hyaline, brownish
at apex and on postei'ior border; the small transverse vein
oblique, about the middle of the discal cell ; the fourth
posterior cell and the anal closed ; the transverse veins
closing the discal and fourth posterior cell are not quite in
a straight line. Halteres reddish yellow.
Stenopogon, Loew.
Linn. Ent. ii. p. 453 (1847).
The genus is distinguished by the very narrow /ace, with
a keel-shaped tubercle, the face becoming narrower still at
antennae, the moustache reaching nearly to the antennae.
Wings with the first posterior cell more or less narrower at
border, the fourth closed or open. In the Australian species
the front posterior cell is hardly narrower at border.

From New South Wales. Coll. M. Fairmaire and M. Bigot.
One specimen in the coll. of Marquis Spinola comes from
Sydney Island, Oceania.
, Macqixart further remarks, in the second Supplement, that
the species which appears common in Tasmania aflbrds him
several subforms. One female differs from the type by the
entire black abdomen, ovipositor, and femora ; another has
the femora entirely testaceous ; in the males the abdomen is
black and the genital organs blackish testaceous.
These remarks are fully borne out by an examination of
Walker's type and others in the Brit. Mus. Coll. D. digentia
has the abdomen entirely black. In some specimens the
testaceous colouring, if present, is confined to the last seg-
ment. The bristles on the legs are often fulvous instead of
the AsW'idse of Australasia. 157

A species very similar to P. albitarsis, but distinguished
by the pale ivings, the absence of white hairs on the fore
tarsi, and by the pi'esence of four black bristles on the breast-
side just above the transverse suture in the type only. The
moustache has more yellow hairs and fewer black bristles,
the colouring ou sides oi face is golden yellow; the hairs on
palpi, on lower part of the first two antennal joints, com-
posing the beard, and round head are yellowish. Thorax
not quite so pubescent. Abdomen with whitish pubescence
only at base and a little short, scattered, white pubescence ou

Damalis, Fabr.
Syst. Autl. p. 147 (1805).
Only one species is recorded from Australia : —
Damalis fuscipennis, Macq., Dipt. Exot. Suppl. 1, p. 222
(1844).
This must be nearly allied to Damalis pandens, Walker,
Proc. Linn. Soc. Loudon, iv. p. 104 [Discocephala'] (1860),
from Celebes, the type in the Brit. Mus. Coll. ; but that of
Damalis lugens, Wlk., from New Guinea, is not to be found.
Doieschall recorded one species, Damalis enjthrophthalmus,
from Amboina.

This genus has not been recorded from Australia itself.
All the Walker species placed in it in Kertesz's Cat. belong to
other genera ; v. d. Wulp records one species from the Island
of Waigou, X. complacita, and Doleschall one from Amboina,
X. rufithorax.

HeteropogoNj Loew.
Linn. Ent. ii. p. 488 (1847).
Dasypogon bcebius, Walker, is recorded from Australia.
Tlie type is not to be found in the Brit. Mus. Coll. It
probably does not belong to this genus, in Avhich it is placed
in Kertesz's Cat. ; but^ as stated above, Loew suggests it
may be a Batliypogon species.
The following Walker species from unknown localities
also placed here by Kei-tesz do not belong to this genus,
having curved spines on fore tibia?, and the fourth posterior
cell is closed, in line with the transverse vein closing discal
cell ; they appear to belong to a genus near Deromyia : —
(Egon, ayiimetus, cerretanus, copreus, silanus, politus. Generi-
cally similar are carvilius under Oligopogon in Kertesz's Cat.,
and volcatius under Isojjogun; they do not appear to be
from Australia.
Dasypogon fossius, Walker, from unknown locality, is
exactly similar to specimens labelled the same from S. Africa,
and is evidently a South-African species; it has spines on
the fore tibise.

Dasypogon, Macquart.
lUiger's Magazine f. Ins. ii. p. 70 (1803).
The species from Australia and Tasmania not yet assigned
to other genera from Dasypogon in sensu lato are tlie
following : —
Dasypogon australis, Macq., Dipt. Exot. i. (2) p, 45 (1838).
Dasypogon albonotatns, Macq., 1. c. Suppl. ii. p. 49 (1846).

Dasypogon carbo. Walker, Dipt. Saund. i. p. 87 (1851).
The type of this last is probably destroyed, not being in
the Brit. Mus. Coll.
Dasypogon australis, Macq.
Type a female seen by me in the Paris Museum, 12. 4. 11.
The head is gone, and Macquart makes no mention of it
in his description ; it is therefore impossible to assign it to
any genus, apparently it will belong to the Dasypogon genus
in sensu stricto. It should be easily recognized by the
wings, which are brown on the fore border, hj the absence
of spines on fore tibiae, and by the black abdomen, with
broad reddish-yellow segmentations, the apex has spines;
no ovipositor visible. Legs yellowish. Thorax black,
shoulders reddish. Scutellum reddish, with long yellow
bristles. The brown colouring on the wings extends along
the fore border to the apex, as far as the posterior branch of
fork of third vein_, fills the first basal cell, the extreme base
of the first posterior, and only touches the discal cell on its
border ; the fourth posterior cell is wide open, anal not
quite closed.
Macquart gives the length as 6 lines.
From New S. Wales.
Dasypogon albonotatus, Macquart.
From Tasmania.
Described as having a long, slender, black abdomen, with
white spots at sides of second to fifth segments. Face and
forehead golden yellow. Beard and the plain moustache
white. Legs red, the anterior tibiae with a curved spine.

Dasypogon nigripennis, Macquart.
Type is probably lost. From New S. Wales.
Described as l)lack. Face white, with a black moustache
confined to oral opening. Beard black. Palpi black with
black hairs. Legs black, the fore tibise with a curved spine.
Wings violet-black, centre o£ cells yellowish. In the figure
of wing the fourth posterior cell is practically closed at
border and anal cell closed. The figure of head shows the
antennae with the third joint about the length of the first
two, with a short terminal style.
Dasypogon nigrinuSj Macquart.
Type, a male, seen by me in Paris Museum, 12. 4. 11.
Furnished with a spine on the fore tibise and the abdomen
is club-shaped, but the short antennae seem to preclude it
from belonging to the genus By'achyrrJiopola or Codula.
Face not very broad ; no tubercle ; moustache confined to
oral opening, composed of yellow bristles ; the face is covered
with yellow tomentum. Palpi black with black hairs.
Antenna very short, the third joint conical, about as long
as the first two together, the latter with black hairs, on the
second a very strong black bristle is present. Thorax black
(denuded). yJ6fi?ome/z black (denuded). Macquart states the
first two segments are shining black, the fifth and sixth with
testaceous segmentations ; no pubescence is visible, but
some white hairs at sides ; genitalia large, protruding, but
not club-shaped ; underside reddish with white hairs. Legs
red, stout, shining ; femora largely black ; tarsi black ;
bristles on legs black and yellow. Wings dark brown,
hyaline at base, only the apices of tlie basal cells being
brown ; the fourth posterior cell is a little narrowed at the
border ; the anal half open ; the small transverse vein is
below the middle of discal cell ; Macquarfs figure of wing
gives this incorrectly, and also makes the fourth posterior
cell too narrow at border.
Length 10 mm.

This genus was formed by Loew for a new species from
Australia, viz. Thereutria calcar, which Loew made the
type of the genus. He separated the genus from Laphria
by the presence of the curved spine on the fore tibiae. It is
as yet peculiar to the Australasian region. The species are
distinguished by the blue-black abdomen often marked with
white spots, by the blue-black legs, the tibise or femora
often yellow, the latter usually stout, curved, t\\Q face with a
prominent tubercle covered by the thick moustache, with
often long hair's continued to the base of the antenna, which

Type, a male, seen in Paris Museum, 12.4. 11, described
by Macquart as from unknown locality : a label below gives
" New Holland " ; no doubt this is correct, as the genus, at
any rate as yet, is peculiar to Australasia. It is a species
of Thereutria distinguished from T. amaracus and T. pulchra
by the wholly black legs and brown wings. A blue-black
species. Abdomen with white spots at sides of segments
2-6. Face with white lines on each side, flat, hardly raised
at oral opening. Moustache white. Antennce gone, except
the first two joints, which are black, with black pubescence.
Wings brownish, the fourth posterior cell narrowed at border,
the anal almost closed.

Type (cJ) from Hunter River, New S. Wales, and
other specimens from Burpengary, Queensland, and New S.
Wales.
Two male specimens from New S, Wales (presented by
J. Hunter) were described by Walker as Ommatius ialmus;
in both the third joint of antennae is wanting and Walker

made no mention of them in his description ; they appear to
me identical with the above. The type of Dasypogon auri-
facies, Macquart, a male^ was seen by me in the Paris
Museum, 12. 4. 11, and is a species of Thereutria identical
with Thereutria amaracus, Walker.
The drawing of the wing by Macquart, pi. vi. fig. 5, is
incorrect, the submarginal cell should be closed not open,
and the small transverse vein is beyond the middle of the
discal cell. Type has the moustache black, two female
specimens with it have it yellow. Antennce now wanting,
except the first two joints, which are black with black
pubescence. Legs reddish ; the tibise pale yellow with black
apices, the anterior pair with curved spine, no black stripe
on the femora.
From New S. Wales.
Macquart^s description precedes the one of D. diversicolor,
which apparently is the same species. Bigot, who had the
type before him, declared it to be a species of Thereutria.
Loew's species is no doubt identical, judging from the
description. Scandon compacta was declared to be identical
with it by Schiner ; the type is not to hand. The type of
Dasypogon diversipes, Kirby, is a female from Sidney, New
S. Wales.
Laphria diversipes, Macq., was described from Sidney
Island, Oceania, and is evidently the same as T. amaracus.
Mr. Froggatt describes it as being a common insect about
Sidney, often taken on fences.
The specimen, a female, described by Bigot as T. caligula,
appears to be an example of this species, as the only
difference in the short description is the mention of the
upper side of femora being black ; in one of the specimens
in the Brit. Mus. Coll. of T. amaracus there is a black stripe,
very short however, beginning at the apex. Bigot gave
Australia as the locality.
The species may be identified by the almost wholly reddish-
yellow legs^ the femora being testaceous, the tibiae yellow,
only their apices, the coxse, and tarsi being black. Abdomen
blue-black, with the typical white side spots on the second
to fifth segments. Wings with the first posterior cell rather
narrow, narrower at the border, the fourth open at border
but narrowed, the anal cell closed at border ; the males
mentioned above have the moustache black, in the females it
is yellow, otherwise males and females seem identical.
Thereutria pulchra, Sehiner.

the posterior pair with the first joint yellow ; pubescence
chiefly black; all bristles on the legs are black. Wings
hyaline, veins brown, narrowly yellow on fore border j
neuration as in Thereutria amaracus.

A genus next to Thereutria, having a curved spine to the
fore tibiae. Antemice with no style, the third joint long
cylindrical. Face with no tubercle and the moustache con-
fined to the oral ope)iing. Wings with the first posterior

almost closed, the anal cell the same.
The only species in general appearance resembles a
Saropogon species.

posterior cell a little more open at border.
Clariola, Kertesz.
Termes Fiizetek, xxiv. pp. 404-406 (1901).
Formed for Clariola pulchra, a male from New Guinea.
The author places tliis genus between Atomosia and Aphestia
in Schiner's table (Verb, zool.-bot. Ges. Wien, xvi. p. 662,
1866), from both of which it is distinguished by the
peculiar third joint of antenna, which has on the upper side
before the middle a small projection with a spine, and also
by its I)ioct7'ia'\\\.e, appearance. C pmlchra is a small
species, only 5 3 mm. The three new species from Queens-
land now added to this genus are large robust flies, very
much larger tiian C pulchra, and the projection on the third
anteunal joint is placed beyond the middle of the joint,
otherwise they seem to agree in all the characters given
of the genus, though the thorn or spine is not visible in
one species, even when examined under a strong lens and
magnified 28 times, but minute hairs fringe the apex.

A black, robust, but smaller species than C alhohirta^ to
which it is closelj^- allied ; distinguished from it by the
moustache being almost wholly white in both sexes, but
chiefly by the white-haired bands of abdomen only being
present on the first two segments, and the apex with white

Type ? and another from Towns villa, Queensland
{F. P. Dodd), 29. iii. 1902 ; and a male aud female from
Mackay, Queensland (G. Turner).
A species distinojuislied from Clariola albohirta and Clariola
pulchra by the golden-haired /ace and hind part of head, and
by the blackish wings.
Length 19 mm. The specimens from Mackay oaly 15
and 16 mm.
It differs from Clariola albohirta in the following parti-
culars : — Face black, covered vrith bright golden tomentum
and with the moustache reddish golden, thick, occupying
the whole of the middle of face to base of antennae. Beard
same colour. Pa//^ismall, black, with black hairs. Antenna
similar to those of C. albohirta, but the spine on the pro-
jection of the third joint is here visible and there are two
bristles on the first joint. Forehead same colour as face. Hind
part of head similar in colouring of pubescence to that of
the face. Thorax shining, blue-black with very short
yellowish-white pubescence, hardly visible to the naked eye,
some black hairs on the posterior border, black bristles
at the sides ; sides and breast the same. Scutellum the
same, bordered with black bristly hairs. Abdomen punc-
tuated blackish with greenish reflections at the apex, the
white pubescence is only visible on the last four segments,
chiefly at the sides ; pubescence on the dorsum black and
short except at the apex, where it is whitish ; sides with
black pubescence ; underside brownish. Legs with no white
hairs on the coxse, no white pubescence is visible on the
femora nor white bristles on these or on the tibise ; the
tarsi have dense white pubescence like the tibise, only the
posterior pair with chiefly black pubescence and no yellow
bristles. Wings blackish, a little lighter on the posterior
border and apex, viewed against the light they appear
brownish with clear spaces ; the other female has lighter
wings than the type ; veins black ; neuration as in C. albo-
hirta, with the exception of the cross-veins not being exactly
in a line, the one which closes the third posterior cell being
a little above the other ; the female has a short appendix.
The species from other parts of the A ustralasian region will
include, besides Clariola pulchra, two of Walker's species
placed under Laphria, viz. Laphria complens, type, from
Celebes, and Laphria obliquistriga, also from Celebes.

From the Annals and Magazine op Natural History,
Ser 8, Vol. xi., January 1913.
A Revision of the Asilidse of Australasia.
By Gertrude Kicardo.
[Continued from vol. x. p. 360.]
Since the last part of this paper was published in the
' Annals' in September 1912, Dr. Hermann, of Erlangen, has
sent me his monograph on the Laphrinse of South America,
in which, however, he includes some species from the Austra-
lasian Region. The monograph was published apparently in
the early part of last year, so that the names of his new
species will have priority over mine. The title of the work
is " Beitrage zur Kenntnis der Siidamerikanischen Dipteren-
fauna," published in Nova Acta Abh. der kaiserl. Leop.-
Carol. Deutschen Akademie der Naturforscher, Band xcvi.
Nr. ].
He forms four new genera for species from Australia and
New Guinea (see p. 205), viz. Cenochromyia, Epaphroditus ,
Adelodus, and Cyanonedys.
Cenochromyia comprises two new species only, from New
Guinea — C xanthogaster and C. guttata (p. 115). Epaphro-
ditus comprises Laphria placens, Wlk., from New Guinea
(p. 118). Adelodus (p. 124) comprises two new species from
Queensland and New South Wales, A. rufipes and A. nigro-
cceruleus ; I have seen no examples of these.
Cyanonedys comprises three new species which I had placed
in the genus Clariola (see ' Annals,' Sept. 1912, p. 357),
viz. Cyanonedys leucura (p. 133 : my Clariola nigrescens) ;
Cyanonedys lugubris (p. 132 : my Clariola aureafacies) ;
Cyanonedys hornii (p. 133: my Clariola albohirta).

Atomosia^ Macquart.
Dipt. Exot. i. p. 73 (1838).
Formed for species from America. No Australian species
has been described as belonging to this genus so far, though
one from New Guinea described by Walker under Laphria
is placed bere by v. d. Wulp ; but a new species from
Victoria appears to belong to this genus. T compared it
with the type of Atomosia affinis, Macq., from Brazil, in the
Paris Museum, and it appeared to agree with it in generic
characters.
The genus belongs to the group with no curved spine on
fore tibiae, and has the cross-veins closing the discal and
fourth posterior cells parallel.
Atomosia australis, ^ ? , sp, n.
Types from Dandenong Ranges, Victoria,
A small blue-black species, with white-haired tibiae.
Wings shaded on the cross-veins.
Length 9 mm. ( c? ), 8 mm. ( ? ).
Face with grey tomentum, brown in centre below the
antennse ; no tubercle present ; moustache consists of rather
long, weak, black hairs, reaching entirely over face as far as
the antennce ; one or two white hairs near the mouth ( ? ) ;
in the c? the face is more widely brown and the moustache
consists of long yellow hairs below and black above. An-
tenna> black, the first joint quite twice as long as the second,
which is small, the third about one and a half times as long
as the first two, with no end-bristle, the first two joints with
black pubescence; back of head with long black hairs, beard
and pubescence on lower part of head white. Thorax
brownish, with short fulvous pubescence ; scutellnm similar,
with long weak bristles posteriorly. Abdomen blue-black,
shining, the same width throughout, finely punctuate ; sides
and apex with fine white pubescence; underside brown;
some black bristles at apex of abdomen. The male has the
abdomen somewhat darker, the genital organs distinctly
visible on the underside. Legs black, coxse reddish brown,
the femora with white hairs below, the tibise covered with
white pubescence on the upper side and with black bristles on
each border, the tarsi with black bristles and pubescence.
Wings clouded with brown on the cross-veins ; the anterior
branch of third vein curved ; the subcostal cell closed in a
point, the first posterior and discal cell narrow, the second
and third wide, the fourth closed, the cross-vein closing it is

and third posterior cells are exactly above the discal and
fourth posterior cell. Halteres yellow.

Stett. ent. Zeit. xlii. p. 386 (1881),
The type (a male) was described from Peak Downs,
Australia ; no specimen in Brit. Mus. Coll. or Mr. French's
Coll. The genus is distinguished by the long third joint of
antenncB and by the transverse veins closing the discal and
fourth posterior cell being in a line. Roder describes his
species as black. Face with white moustache and beard.
Abdomen copper-coloured at base, steel-blue shining on poste-
rior borders with white hairs; the remaining segments
shining copper- coloured. Legs steel-blue.
Length 7 lines.
Dr. Hermann suggests that this species may belong to his
new genus Adelodus : see his remark, p. 135.

which is large and takes up the greater part of face, is
shining black in the middle and carries the moustache com-
posed of long black bristles. Palpi blackish, with black
bristly hairs. Beard whitish. Proboscis at base with long
whitish pubescence. Antenna blackish, the first joint two-
thirds the length of the third joint, with white hairs and one
long reddish-brown bristle at its apex ; the second very short,
not half the length of the first, with a long black bristle
on each side; the third rather broad and flat, with no style.
Forehead and hind part of head with whitish pubescence.
Thorax blackish brown, with grey tomentutn on shoulders
and continued as stripes median and lateral ; the pubescence
on dorsum short, chieHy greyish, sides with longer hairs and
with three or more black bristles above the base of wings
and three weaker ones beyond ; breast-sides with chiefly
long greyish pubescence. Scutellum with grey tomentum
and pubescence.
Abdometi metallic blue-black, the first two segments
covered with long grey pubescence, which, however, does not
attain the posterior border of second segment ; the other
segments bare ; the anus with black hairs ; sides of abdomen
with two black bristles on the first segment and one each
on the following four segments ; underside with long pubes-
cence black, except at the base, where it is greyish. Legs
blue-black, with long greyish hairs on the femora and tibiae,
the tarsi armed with black bristles and a few bristly hairs ;
the posterior femora incrassate, with some stout black
bristles on the apical half, the middle femora with two at
the apex. Wings clear, veins brown, slightly shaded ; the
first posterior cell closed at border (in one male from Queens-
land it is almost open at the border and there is an
appendix present) ; fourth and fifth posterior cells closed, the
small transverse vein situated on the basal third of the discal
cell.
Female is similar, but the pubescence at base of abdomen
and on legs is much less, and on the hind femora, which are
not so incrassate, it is largely black ; the ovipositor long and
pointed.
Andrenosoma vidua, Bigot, appears to me from the descrip-
tion to be identical with this species.
Maira, Schiner.
Verb, zool.-bot. Ges. Wien, xvi. p. 673 (1866).
This genus comprises blue-black metallic species with
swollen hind femora, and all the legs, especially in the males,
the Asilidse of Australasia. 151
with long pubescence ; the head orbicular and much excised
behind ; the moustache confined, or almost so, to oral
opening. The genus is chiefly confined to the Oriental
and the Australasian Regions, but so far only three species
have been described from Australia, Tasmania, and New
Zealand.
The synonymy of some of the species is in the greatest
confusion, largely owing to the difficulty of identifying
Walker^s species from his descriptions. Below is given what
appears to be the correct synonymy for a few of the Walker
species from the Australasian Region (Australia and New
Zealand excepted) from examination of the types, but little
can be done till the genus is thoroughly monographed. The
species recorded from Australia and New Zealand are only
two : —

Maira auribarbis, Macquart.
Laphria consobrina, Walker.
The male type was described from Java, and later Macquart
recorded a female from Australia.
The type is apparently lost.
Macquart placed it under Lumpria, a genus confined to
the American continent, with spines on underside of hind
femora ; in Kertesz's Cat. it is placed under this genus.
In Brit. Alus. Coll. : — Walker's type (?) from Waigiou

Queensland.
From Macquart's description this species is probably the
same.

femora and tibiae with long yellow hairs. Wings : the ante-
rior half hyaline, posterior half blackish brown ; neuration

From Java, my collection (Suppl. iii. p. 182).
Male has been described. A female is placed with it,
which differs as follows : — Posterior femora less incrassate ;
tibiae with mucli fewer long hairs. Wings brownish^ a little
paler towards the base. The first transverse vein is situated
on the third instead of the quarter of the discal cell. It
comes from New South Wales, whilst the male is described
from Java (Suppl. iv. p. 375).
The /ace in Walker's species is bright golden yellow, with
the same coloured hairs above tubercle, which latter is
blackish with grey tomentum ; the moustache composed of
eight long black bristles, the golden-yellow hairs intermixed
with them ; the second, third, and fourth segments of abdo-
men have traces of white spots, and underside has white
segmentations. Winys clear at base and on fore border as
far as stigma ; elsewhere brownish.
Lengtli 17 mm.
The other specimens vary somewhat in colouring of iving ;
one specimen from Amboyna has them entirely hyaline and
they vary in size from 12-23 mm.

appears to me to be the same as M. spectubilis ; it is a large
species, measuring 23 mm. Moustache of long black hairs,
with some yellow ones below intermixed, and yellow hairs on
face. Antennce black, the third joint destroyed. Thorax dull
blackish, with white spots on shoulders. Abdomen and legs
metallic blue, the latter with long white hairs on all the
femora and tibise, apices of latter with some black ones and
the tarsi with long black hairs. Wings tinged brown, the
fourth posterior and anal cell closed, the first posterior wide
open.

Type ( (J ) from Key Island.
The species described by v. d. Wulp as M. tomentosa must
be very near this species, if not the same.
To the Walker species under Maira in Kertesz's Cat. the
following should be added : —
Laphria setipes, from Gilolo.
Laphria conveniens, from Batjan and Gilolo.
Laphria Jiagellat a, from Gilolo.
Laphria, Meigen.
Illiger's Magazine f. Ins. ii. p. 270 (1803)
This genus is distinguished from Maira, Schiner, by the
thicker moustache, which is not confined to the oral
opening, but extends upwards ; face usually with a tubercle.
The character of the head beiug not or only very slightly
excised behind seems rather a doubtful one ; indeed authors,
V. d. Wulp in particular, seem to difi'er as to the characters
of Maira, which was divided ofi:' from Laphria.

Moustache of stout black bristles, one or two yellow ones
near mouth. Third joint of antennae yellowish. Scutellum
Avitli long, black, fine bristles. Ovipositor with long yellowish
hairs. No curved spines on fore tibiae. Wings yellowish,
with brown markings, situated at the apex, on discal, fourth
and fifth posterior, and upper part of second basal cell ; the
apical marking does not extend beyond the base of fork of
third vein, the second and third cells are only partially
filled with brown, and the anal cell only in its upper half.
Macquart's figure of wing does not represent the brown
colour very correctly.
In Brit. Mus. Coll. and Mr. French's Coll. male and
female from Queensland.
A species easily recognized by the colouring of the ivings
yellow and brown and by the depressed, narrow, metallic
bluish-black abdomen, with white lateral spots.
Length 17 mm.
The wings in these specimens are yellowish, the apex and
posterior border brownish, the dark colouring extending to
base of branch of third vein in a straight line from costal
border to the posterior border to base of first posterior cell,
continuing and occupying all the remaining posterior cells
and most of the anal cell ; base of wing nearly hyaline ;
the first posterior cell open, fourth closed, the small trans-
verse vein on basal third of discal cell. The scutellum in
male is armed with long bi'istles, yellow in the centre and
black at the sides ; in the female all are black. The ovi-
positor of female small, ending with long yellowish hairs.
The third antennal joint in the female is wholly yellowish.
The moustache in the male consists of golden, soft, long
hairs.
Laphria niveifacies, Macquart.
^ This species, placed under Maira in Kertesz^s Cat., is more
probably a species of Laphria, judging from the description
of the moustache.
The type is apparently lost, as it was not to be found in
the Paris Museum.
Macquart describes it thus : —

white. Legs violet, with white hairs and black spots ; poste-
rior femora incrassate ; posterior tibise swollen and curved.
Wings : the anterior half hyaline, the posterior half
brownish ; neuration normal.
From Tasmania. Paris Museum.
In the figure of iving the small transverse vein is below
the middle of discal cell, the first posterior cell narrower at
border, the fourth and anal cells closed.
Wulp described a female specimen from Sumatra which
he thought might belong to this species, measuring 6*5 lines.
He placed it under Maira, on account of the incrassate
posterior femora and metallic colour of the legs. The wings
were black-brown at the apex, extending into the basal cells,
and the white hairs at sides of abdomen were not apparent.
Laphria flavifemorata, Macquart.
Type ( ? ) seen in Paris Museum, 12. 4. 11.
A small species, measuring only 9 mm., blue-black in
colouiing, with yellow femora.
Face fairly broad, with a large prominent tubercle.
Moustache composed of black bristles. Beard white.
Thorax with some whitish tomentum at the sides and long
soft black hairs at sides, with shorter ones on the dorsum.
Scutellum identical. Abdomen bare, shining, no white spots
visible, with short black hairs at sides. Femora below with
white hairs, hind pair a little incrassate ; tibise with long
black hairs. Wings hardly brown, as Macquart descrilies,
clear, with black veins, the first posterior cell narrowed at
border, the fourth and anal closed; the small transverse
vein very near the base of discal cell, just above the base
of the fourth posterior cell.
This is a very much smaller species than Laphria tekcles,
Wlk., with which I compared it.
Laphria calopogon, Bigot.
A male from Australia.
Described as black, with long grey pubescence below
abdomen and femora and on both sides of tibise. The
borders of the second, third, and fourth segments of abdomen
fawn-coloured or testaceous. Femora at base and fore tibise
at base with red spots. Wings blackish.

are replaced by three black ones. The spots on abdomen
are not visible, and only the sixth segment is reddish yellow,
and on the posterior border only ; the genitalia are shining
black and prominent ; the middle and posterior femora are
not yellow on their basal half.
Laphria fulvipes, ? , sp. n.
Type (?) and two others from Mackay, Queensland
(G. Turner-).
A small species with black legs, distinguished by the
femora being yellow on their basal half and by the yellow
tibise, which are black at their apices on the middle and
anterior legs and on the posterior pair more widely so.
From L. hirta it may be distinguished by the less pubescent
legs and by the white spots on the dull black abdomen. The
face has a black moustache, with long golden-yellow hairs
above reaching to the antennse ; pubescence on forehead and

paler on the fore femora, and long black pubescence on the
black parts, the tarsi with wholly black pubescence. Halteres
red-brown. Wings brownish ; neuration as in Laphria
rufifemorata.
The species in the Laphria genus from New Guinea and
other parts of the Australian Region are very numerous.
Of the Walker species, on an examination of the types the
following remarks are based : —
L. ampla, from Amboyna, appears to be identical with L. vulcanus, Wied.
L. argentifera and L. conveniens probably belong to the genus Maira.
L. declarata appears allied to the genus Atoinosia.
L. aperta and L. tripars, from New Guinea and Waigiou, appear identical ;
they are very small in size ; Dr. Hermann places the latter in his
new genus Cenochromyia (see p. 117). L. pipunculoides, also a very
small species, has a striking character in the eyes, which take up
nearly the whole of the head and are joined in the middle ; Dr. Her-
mann places it in the genus Clariola (see p. 113).
160 Miss G. Ricardo — A Revision of
The following species are from Celebes : —
L. dioctroides, a very small species witla a very nai'row face, bearing a

pi. xii. fig. 10 [^Dasypofimi] (1835), seen by me in the British Museum.
The thorax is covered with brigrht fulvous tomentum; the antennae,
face, beard, and legs are the same colour ; on the sides of thorax and
breast a brown median stripe appears. Abdomen dull brownish
red. Wings brown, with white streaks — one at apex, another be-
tween the first and second posterior cells, and smaller ones in the
cells. Laphria concludens, Wlk., from Celebes, appears very nearly
related, if not identical.

Blepharotes flavus, sp, n.
The genus was established by Macquart for Asilus cori-
arius, Wied., and is peculiar to Australia and New Guinea.
It is at once distinguished by the very broad abdomen
adorned at the sides by bushy tufts of hairs and by the
short terminal style of antenna?. The species described by
Loew as B. macrostylus 1 have placed in a new genus, Par-
aratus, as, owing to the form of the female ovipositor, it
could not possibly be included in this genus.
In neuration of the wing Blepharotes is allied to Pararatus,
Neoaratus, and Asilus in sensu stricto ; its place among tlie
other genera appears doubtful. For the present I liave
followed Schiner, and placed it at the head of genera with
antennal bristle bare.
Blepharotes coriarius, Wiedemann.
Specimens of this species, male and female, are in the
Brit. i\lus. Coll. from W. Australia (Ft/son), Melbourne, and
Moreton Bay^ and in Mr. French's Coll. from Dandenong
Ranges, Victoria. Mr. Froggatt states that the species is
widely distributed all over the interior of the continent,
and can often be seen flung about with its beak buried in
the back of a lar^e cockchafer beetle, its long legs clasping
its victim and sucking its blood.
The species is distinguished by the red colour of the
abdomen, sides fringed with black tufts of hairs, white hairs
appearing on the second, fifth, and sixth segments; under-
side black, with white pubescence. Palpi often have white
hairs intermixed with the black ones. Fore femora armed
with spines as well as the posterior ones,

Specimens of this species, males and females, are in the
Brit. Mus. Coll. from Victoria, Moreton Bay, and. Burpeu-^
gary, S. Queensland (^Bancroft), and in INIr. French's Coll.
from Dandeuong Ranges, Victoria. Mr. Froggatt remarks
he has frequently captured this species flying about the
Botanic Gardens, Sydnej^, in early summer.
The species is distinguished by the dark brown loings and
black abdomen, the segmentations narrowly rufous ; sides
with black tufts of hairs.
Length from 25 mm.
Blepharotes vivax, ? , Hermann.

from Victoria.
This species is nearly related to B. coriarius, Wied., but is
distinguished by the lighter-coloured abdomen, Avhich is
yellowish, not deep fulvous red ; the wings are usually rather
paler, and the size of insect is smaller, the abdomen not so
broad ; the white hairs on the sides of this latter are present
on each segment except the last two, not only on the third

and sixth as in the Wiedemann species. A tuft of white
hairs is present on the forehead, which is usually absent in
B. coriarius, and the white hairs on the coxai are chiefly
limited to the anterior pair. It is distinguished from B. vivax,
Hermann, by the absence of any bright colouring on the
thorax, and the wings are lighter, not black with violet
reflections ; the abdomen also paler.
Male. — Abdomen pale yellow, rather narrow compared with
those of other species of this genus, bordered by black tufts
of hair, with which white hairs are intermixed below.
Length 30 mm.
Face black, covered with yellowish tomentum, and with
long pale yellow bristles forming the moustache, chiefly con-
finetl to the oral opening. Palpi with black hairs. Beard
white. AnteniKB black, the third joint long, with a short
bristle. Forehead with black pubescence, and a tuft of
white hairs anteriorly on each side. Hind part of head with
long white hairs and some shorter black hairs at vertex.
Thorax black, with some grey tomentum on dorsum ; sides
with black bristles and grey tomentum ; breast black, with
grey tomentose stripes. Scutellum dark brown, with black
bristles. Abdomen with the first segment black, with black
hairs, the remaining ones pale yellow, tlie posterior borders
paler ; the white hairs at sides are below the black ones and
most apparent on the fourth, fifth, and sixth segments ;
underside dark brown, with chiefly black pubescence. Legs
black, femora armed with black bristles, the pubescence on
the fore coxse long, yellowish white; a few are visible on the
other coxie, otherwise their pubescence is black. Wings dark
grey, with reddish-yellow veins, the posterior branch of fork
strongly curved, the second [)osterior cell wide, almost
touching the former vein at one. place; the third posterior
very wide, twice the width of the second at its widest part;
t!)e fourth posterior closed, the anal closed near the border;
the small transverse vein about the middle of the discal cell,
which is long and narrow.
Female. — Abdomen is darker yellow and broader, not so
glabrous as is that of B. coriarius ; the white hairs at sides
are more apparent than in the male. Ovipositor blackish,
short, not compressed at sides.

stripes ; some very short, inconspicuous, black pubescence
on dorsum ; sides with black bristles and covered with grey
tomentum below and white pubescence ; thorax posteriorly
and scutellum on its posterior border with black bristles, the
latter black, with grey tomentum and some white hairs.
Abdomen in ^ stout, robust, appearing black on each seg-
ment, with the posterior borders and the sides grey, pubes-
cence on dorsum chiefly black, at sides with thicker whitish
pubescence ; venter black, but covered with grey tomentum
and with fine white hairs ; genital organs black, with black

spots are smaller and more distinctly marked, the pubescence
even on the black spot chiefly yellowish but shorter; ovi-
positor black, shining, with white pubescence below. Legs
red, the coxoe, knees, and apices of tibiae, and all tarsi black ;
posterior tibiae more largely black, especially in the ? ; coxae

This species differs from P. rujipes in having white-haired
palpi, the black spots on abdomen not triangular, and in the
femora and tibiae being the same colour, with some white
bristles, and the size of P. rufipes is only 20 mm.
A male from Endeavour River, Queensland, and a female,
both in Mr. French's collection, differ from the above by
having the moustache and the palpi of black and white hairs,
and the femora have no white bristles ; for the present they
may be considered as only a variety of P, doddi.

Williston in his 1908 edition of ' Manual of N. American

genus Asilus very vague and often not based on true generic
characters, and placed them in his table of genera as sub-
genera. Prof. Hine in " Robberflies of the Genus Asilus,'^

The description of this reads suspiciously like that of
Heliymoneura lascus, Walker ; but this genus is distinguished
by the broad third joint of antenncR, almost the same widtli
throughout; this last particular is true of H. lascus, but the
width is not very great. Scliiner gives uo idea of the
proportion of the width to the length.

This genus has not been recorded before from the
Australasian Region ; but two species are known from the
Oriental Region, one being Asilus atraiulus, Wlk., the type
of which is in the Brit. Mus. Coll., from Java, a species with
the legs black. I believe Asilus antilco, Walker, belongs to
this genus, but it is in bad preservation. There is a female
from Queensland which also appears to belong to this genus,
but is a different species.

Types ( c? ? ) from Coleuso, New Zealand, also recorded
by Hutton from Auckland and Wellington, New Zealand.
The types presented by Dr. Hooker are not identifiable,
but there are male and female specimens from New Zealand
(Col. Sinclair, 1845) and otliers (Col. Botton, 1854), which
agree with the description given by Walker. This species
and another new species from New Zealand, S. meridion-
alis, were placed by Hutton in the genus Sienoprosopis,
containing species from America, with the exception of one
from Bengal ; this species, however, belongs to Heligmoneura,
having the face very narrow, raised round the mouth, forming
a very slight tubercle (in Stenoprosopis the face has no
tubercle and the moustache is composed of only a few long
hairs), and appears nearly allied to H. gnava, v. d. Wulp,
from Java, Obi, Halmaheira, and Waigiou. Stenoprosopis
meridionalis, Hutton, Trans. New Zealand Inst, xxxiii. p. 23,
will probably prove to be a species of Heligmoneura.
H. lascus is described as a small species with reddish-
yellow legs, the abdomen black, with rather broad greyish or
dull yellowish segmentations. Wings clear, grey at apex
and round posterior border.

Pararatus, gen. nov.
Allied to Aratus, v. d, Wulp (now Neoaratiis) , in having no
bristles on the abdomen, and in the neuration of the luing,
but is distinguished from it by the non-dilation of the
wing on its fore border in both sexes, and by the genital
organs, which in the male are very large and club-shaped ;
the ovipositor of the female is compressed at the sides,
bringing it thus near Neoitumus in this respect, from which,
however, the neuration of wivg and large size of the species
distinguish it. It is also allied to Blepharotes iu the large
genital organs of male. From. Asilus in sensu slricto it is
distinguished by the character of these organs.

430 Miss G. Ricardo — A Revision of
collections under B. coriarius. After carefully studying bis
description of his new species I am convinced the above
specimens are identical with his species macrostijlus and that
they do not belong to the genus Bhpharotes, though it is
very unlike Loew to have overlooked the following characters
which preclude it from belonging to Blepharotes, viz. : ovi-
positor of female, which is long and compressed at sides ;
short style of antenna and short third joint, the absence of
thick tuft-like hairs at sides of abdomen, and the very much
slighter build of legs; these last three characters were
noticed by Loew in his description, but of the ovipositor he
makes no mention. The neuration of wings is very similar.
Small males of Blepharotes flava have a slight general
resemblance to this species, but the thick tuft-like hairs at
sides of abdomen will at once distinguish them.
This is a large species : abdomen fulvous with reddish-
yellow pubescence and black apex; thorax blackish; ivings
large, hyaline. Legs wholly black.
Length 27—35 mm.
Male. — Face blackish, covered with yellowish tomentum ;
the tubercle large, occupying the lower pai't of face, bearing
the moustache composed of long white hairs. Palpi black,
Avith black hairs. Antenna black, the third joint with a long
terminal biistle ; the first two joints short, the first the
longest, both with black hairs ; the third conical, with a
rather long tapering point, the joint a little longer than the
first two joints together, the bristle nearly as long as the
joint. Forehead brownish black, with white pubescence,
white hairs on hind part of head, a few black hairs at vertex.
Thorax brownish black, with black pubescence and two long
bristles before the suture, two beyond, and several on
posterior ])art of thorax ; sides and breast with white pubes-

Types of Asilus varius consist of two males, co-types, one
presented by Col. Sinclair, one from Mr. Earl's collection ;
and three females, co-types, added in the 7th volume ' List
Dipt. Brit. Mus./ from Auckland, presented by Col. Bolton ;
a long series of specimens are in the collection from New
Zealand.
A small blackish species, the legs bluish black ; tibiae
reddish yellow. Wings hyaline, greyish round the posterior
border and at apex.
Length, S 17-18 mm., $ 18 mm.
Face black, with white or yellowish tomentum at sides ;
tubercle large, black, shining ; the moustache composed of
many black bristles and a few long white hairs below.
AntenncB with black hairs on the first two joints. Beard
white and the hairs round head white. Head excised a little
behind, with black incurved hairs at occiput. Thorax black,
with two ashy-grey or yellowish tomentose stripes, grey at
sides, the pubescence on dorsum black and some short black
bristles present, with longer ones at the sides. Scutellum the
same, with four large black bristles on posterior border, often
yellow in the female. Abdomen black, with grey or whitish
segmentations and short black pubescence, some white hairs
at base on segmentations and yellow bristles at sides ; geni-
talia in male club-shaped, large, swollen at tips, black and
shining with black hairs and a few white ones intermixed ;
ovipositor in female long, including the sixth and seventh
segments of abdomen. Legs black ; femora with long white
hairs below, the middle and posterior pair with bristles on
underside ; tibise testaceous ; bristles on legs black. Wings
with the small transverse vein at or beyond middle of discal
cell.
Walker's var. B of bulbus, a female, is identical with, the
types of varius.
Itamus melanopogon is identical, judging from the de-
scription given by Schiner; the type came from Auckland.
The original description of N.frafernus, by Macquart, of
male and female is very short. V. d. Wulp described more
fully a female specimen from Rawas, Sumatra, he considered
to be identical with it ; the only difference in the description
appears to be that the outsides of tibiae have a black stripe

Neoitamus bulbus. Walker.
Itamns inquisitor, Nowicki,
Tvpes, two female co-types (not a male and female as
Walker states) ; one measures 22 mm. in length, the other
14 mm., which roughly corresponds to Walker's length
6^-10 lines, so that it appears probable he mistook one of
these females for a male. Both are in a very dirty dilapi-
dated condition, but they correspond fairly to the long
careful description giveu by Nowicki and appear to be the
species h3 was describing. It may be distinguished from
N. fraternus at once by the presence of spines on the fore
femora below and by the colour of the legs, which are chestnut-
coloured, the femora with a black stripe below ; apices of
tibiae and all the tarsi black, the moustache is entirely black.
Nowicki mentions some yellowish-white hairs ; his type also
came from New Zealand.
The var. B of Walker does not belong to this species, but
is identical with N. varius, Wlk.

This genus was formed for Asilus hercules, Wied., by
V. d. Wulp, who satisfied himself as to the probability of
the correctness of the three synonyms (see below) ; he also
suggested that Rhadiurgus macquarti, Bigot, and Asilus
tasmani(S, Macq., might belong to this genus, which he
characterized as follows : —
Face moderately broad, with prominent tubercle, which,
with the thick moustache, takes up two-thirds of the face.
AntenncB small in proportion, the two basal joints same
length ; the third rather shorter than the two together,
pointed at end, with a naked arista. Thorax short-haired,
only posteriorly with some long hairs, but without bristles.
Abdomen fine-haired, slender, no bristles at sides; eighth
segment hidden (correct only of cJ ) ; genital organs small ;
ovipositor egg-shaped, with two small lamellae at end. Legs
stout, femora not incrassate. Wings shorter than body, in
the male dilated on the fore border; the submarginal cell
rilled in both sexes ; the discal cell long and narrow, the
upper vein from it very much bent outwards, so that the
second very broad posterior cell bulges very considerably
into the first one ; the fourth is closed, also the anal cell.
This last character is common to the large species of
Asilus, such as rufiventris, rufithorax, pelago, hyagnis, and
the submarginal cell is frequently rilled in them, and even
the fore border of wing very slightly dilated, so that it
appears as if the very great dilatation of wing on fore border
in Neoaratus hercules is the only character that divides it
off from Asilus in sensu stricto, and it remains the only
species in the genus. Rhadiurgus macquarti is a male from
New Caledonia ; Bigot makes no mention in his description
of the wing being dilated ; without seeing his tyjie it is
impossible to decide whether he placed it in the right
genus.

A very large, dull, blackish-brown species, 30-40 mm. in
length. Wings in males very much dilated on fore border.
Face with distinct tubercle, the moustache composed of
black and yellowish hairs. Antenna have the first joint
twice as long as the second (not equal in length as v. d.
Wulp states). Abdomen with yellowish-grey tomentum and
very short fulvous pubescence on dorsum, sides with longer
yellowish hairs. Male genitalia rather large, black. Female
ovipositor small, the eighth segment distinct. Legs stout,
red; base of femora, knees, and tarsi black, the numerous
bristles are black. Wings much dilated in male, not usually
so in females, but the suhmarginal cell is rilled as in male,
hyaline, with yellowish-red veins ; posterior branch of third
vein strongly curved ; second posterior cell broad at base,
bulging into the first one ; the third nearly as wide as the
second, the fourth and anal cell closed, the small transverse
vein beyond the middle of discal cell.
AsiLUs in sensu stricto.
Linn,, Syst. Nat. ed. x. pp. 605, 227 (1758).
This genus, in the narrowest sense, is usually defined as
comprising large bright-coloured species ; the abdomen at
sides near the segmentations without any bristles ; dorsum
with short appressed pubescence ; ovipositor conical, not
compressed. The following species appear to belong to this
genus, but Asilus inglorius and discutiens differ from the
other species by the presence of thick tufts of hair on the
basal segments of abdomen, on dorsum, though not reaching
the median line ; they approach Pamponerus in this character,
but the facial tubercle and non-contrasted colouring of wings
prevent their inclusion in that genus.

Asilus amycla, $ , Walker.
Asilus centho, S , Walker.
Asilus i^lanus, § , Walker.
The types of amycla and centho are from New S. Wales;
the type o( planus from Australia.
There is a long series of specimens in the Brit. Mus. Coll.
from Burpengary, Queensland. The identification of this
apparently common species with Asilus inglurius, Mackay,
is given on the authority of Schiner, who confidently asserts
it, but the original description consists of merely a few lines.
Schiner suggested that A. planus and probably A. amycla were
synonyms of it, and was correct. The species is easily dis-
tinguished by the bushy bright yellow hairs on the three
basal segments of abdomen and by the red legs with tarsi
black.
Length, S ~^, ? 24 mm.
A series of this species is labelled in the Paris Museum as
Asilus sericeivent7is, eYidenily a MS. name only of Macquart's.

The species is nearly allied to Asilus ingloi'ius, Macleay,
but is distinguished by the more robust form of the males
and by the darker colouring of the abdomen in both sexes
and by the thick hairs on abdomen being continued on the
sides of the third segment. It is blackish in colour, with
tufts of yellow hairs and short yellowish pubescence on the
abdomen. Palpi with black pubescence, and the yellow
moustache has some black hairs above and below. The
yellow bristles on the legs mentioned by Walker appear only
as two paler bristles on the posterior tibiie in the female,

Jaennicke ; smiihii, Hutton.
Asilus crabroniformis, L.^ in Kertesz's Cat., has Tasmania
given with a query as one of the localities in which it occurs ;
but this is probably an error on the part of Walker (see
Verrall, 'British Flies/ vol. v. p. 649, 1909).
The following Walker types from Australia and Van
Diemen's Land are not to be found in the Brit. Mus. Coll.,
and should be expunged from any future list : —

The following types from unknown localities are also not
to be found : — Asilus eanes, habnus, and inumbratus.
Asilus antiorus and corythus are species of the genus
Fruct acanthus.
The following types of Walker cannot be placed in their
correct genus, owing to their imperfect condition ; all, with
the exception of Asilus alcetus, are small species which will
not belong to Asilus in sensu stricto.
Asilus obumbratus, Walker.
Dipt. Saimd. p. 145 (1851), et List Dipt. vii. Suppl. 3, p. 735 (1855).
Type (female) from New South Wales (Saunders Coll.)
seems allied to the genus Cerdistus, but the ovipositor ends
in a fork. It is a small black species with apparently dull
yellow legs.
Asilus alcetus, Walker.

? Asilus traehalus, Walker, Dipt. Saund. i. p. 143 (1851), et I.e. p. 738.
This type is from Van Diemen's Land {R. Buller), in bad
preservation. A medium-sized greyish-black species.
448 Miss G. Ricardo — A Revision of
Scliiner placed it in the genus Neoitamus, but it does not
belong to that genus, and the species Scliiner described in
Yerh. z.-b. Wien, xvii. p. 408 (1867), must be an altogether
different species from this type, which is apparently an Asilus
species, though the sides o£ abdomen have strong black
bristles ; ovipositor small, conical. Legs red, tarsi blackish,
fore femora with some black bristles below. Moustache
chiefly yellow.
The type of Asilus trachalus from same locality, a female
in a very greasy state, is probably identical with the above.
Asilus coedicius, Walker.
List Dipt. ii. p. 457 (1849), et vii. Suppl. 3, p. 735 (1855).
Type from New Holland (abdomen destroyed) and another
female may possibly belong to the genus EiUulmus, but are
in too imperfect a state for identification. A small black
species, with the tibiae partly yellow.

List Dipt. ii. p. 461 (1849), et vii. Suppl. 3, p. 737 (1855).
Type (female) from Melbourne has lost its abdomen. A
small black species with tibise dull testaceous. Walker
suggests his Asilus coedicius may be a variety of this species.
Asilus villicatus, Walker.
Dipt. Saund. i. p. 147 (1851), et List Dipt. vii. Suppl. 3, p. 734 (1855).
The type (a female), from New South Wales, is very
small ; the male type mentioned by Walker is not to be
found. It was suggested by Scliiner that it might be iden-
tical with his Neoitamus mehmopogon, now identical with
Neoitainus varius, Walker ; this is not the case, and the
species hardly seems to belong to the genus Neoitamus. Till
further material is available, its correct generic place must
be left uncertain. In size and general appearance it seems
related to Asilus exilis, Macquart.
The following three types of Macquart, seen by me in the
Paris Museum, 12. 4. 11, could not be placed in their correct
genus either owing to being isolated specimens or because
of their state of preservation.
the Asil'idse of Australasia. 449
Asilus exilis, Macquart.
Type (a male) seen by me in Paris Museum, 12. 4. 11.
A very small species, measuring 12 mm.
Face narrow, with a distinct tubercle. Moustache com-
posed of many white and black hairs. Antennce black, the
first two joints with black hairs, the third conical, with a
long arista. Thorax black, marked with grey tomentose
stripes and with black bristles at sides and posteriorly ;
sciitellum with white bristles. Abdomen blackish, with lighter
segmentations and pale pubescence. Legs black, tibise and
coxae reddish, femora with white hairs below. Genitalia
club-shaped, with fine filaments below.
Asilus vUlicatuSj Wlk., might possibly be identical.
Asilus laticornis, Macquart.
Type (a female) in very bad preservation, with the antennae
destroyed, seen by me in Paris Museum, 12. 4. 11.
It is evidently a small species of the genus Asilus in sensu
lato with the neuration of wings normal, the fourth posterior
cell closed, the small transverse vein situated just beyond
the middle of discal cell. Abdomen with a short conical
ovipositor, the segmentations greyish tomentose. Legs
black, tibise apparently testaceous.
In Macquart^s figure of the antenna the third joint is
short, about as long as the first two together, and broad,
with a terminal arista shorter than the joint itself.
Asilus varifemoratus, Macquart.
Type seen in Paris Museum, 12. 4. 11 ; part of the abdo-
men gone.
A small species. Moustache white, antenna black. Abdo-
men black, the pubescence white ; segmentations appear to
be reddish. Legs black, femora witli white hairs below ;
tibiae yellow-red, black at apices ; tarsi yellow-red, black at
apices, bristles largely white. Wings clear, grey at apex, the
fourth posterior cell closed.
Of the Asilus species of Walker from other parts of the
Australasian Region, Asilus areolaris ^ ? and areolatus ^ ,
from Celebes, are species of Pamponerus. Asilus determinatus
and introducens are nearly allied to Asilus discutiens, Wlk.,
having tufts of bright-coloured or white hairs on basal seg-
ments, but the ovipositor in females seems entirely diflferent.
450 Miss CI. Ricardo — A Revision of
Asilus condecorus type appears to be lost. Asilus biligatus,
didymoides, depnlsus, and tenuicornis appear to be species of
Asilus in sensu stricto. The generic place of Asilus complens,
lavis, and superveniens appears to me doubtful.
Pamponeurus, Loew.
Linu. Ent. iv. p. 135 (1849).
This genus was divided off from Asilus by Loew, being
distinguished by the long outstanding pubescence on abdo-
men, whereas in Asilus the abdomen is almost bare. Wings
with two strongly marked colours, usually whitish at base.
Face with a large tubercle ; moustache nearly reaching the
antennse.
The species are few.
The type of genus is the widely spread European P. ger-
manicus ; the only other species are P. nigritulus, v. d. Wulp,
from Molucca Isles, P. mendax, Wlk., from Celebes, and
P. areolaris ^ ? and areolatus J", Wlk. \_Asilus'], also from
Celebes.
The typical colouring of wing is only present in the male
oi areolaris, a species very similar to mendax, but the legs
are almost wholly reddish yellow.

tions grey. Face yellowish or grey ; moustache black, with

EuTOLMuSj Loew.
Linn. Ent. iii. p. 459 (1848).
A species described by Macquart as Asilus armatus (see
Dipt. Exot. Suppl. 1, p. 219, pi. viii. fig. 17, 1846) has been
placed, evidently in error, under Eutolmus in Kertesz's Cat.
The reference given to Loew, Beschr. Europ. Dipt. ii. p. 164,
note 2 (1871), refers to Machimus armatus, Jaenn., a Euro-
pean species now stated to be a synonym of Machimus pi/ipes,
Meig. From the figure of Asilus armatus it is evidently not
a species. of Eutolmus or Machimus, if the figure is at all
correct. -'<^'"^"'^'^-=' ^
The genus has thus not yet been recorded from the
Australasian Region nor from the Oriental Region.

These females agree with the description with the exception
of the bristles on the tarsi, which are black, not white as
stated by Macquart, but the rounded angle of the anterior
branch of the fourth vein emitted from the discal cell is
present, though not quite so exaggerated as given in the
figure; the wiiite hairs below the first two joints of tlie
antennce are here more reddish and black. Forehead with
black bristly hairs. Thorax with white tomentum on the
testaceous sides. Prsesutural bristles three in number — one
supraalar, two postalar, — all black, and three or four weak
dorso-central bristles on each side, pubescence on dorsum
black and numerous. Scutellum brown, with grey tomentum
and four black bristles on its posterior border. Abdomen
with two black bristles on each side of the first segment ;
dorsum with short white pubescence, and the usual circle of
spines at apex. Femora and tibiae with short white jMibes-
cence also present on the first joint of the tarsi and partly on
the other joints ; all the legs with numerous black bristles.

A male and female from Queensland and a female from
Sydney have a good many black bristles on the legs, and the
four bristles on the scutellum are black, not yellow. Others
from Queensland have the pale colour of the legs more yellow
than red, and are smaller in size.
This appears to be a rather variable species, differing in
size and general appearance.

'J^his has been pLiced in a new genus Trichoitamus by the
late Mr. A. VV^hite, who draws attention to the difference in
the ovipositor from Di/smachus, the lamellae being free, not
wedged in as in the last-named genus. Owing to the War,
Mr. Whitens paper has not yet been forwarded to this country,
but owing to his brother's kindness I have had the MS. to
study.
Mr. Gibbons sent me males and females of this species
from Sydney. These differ somewhat from the type in the
colour of the legs, which are darker, the tibias only dull red
at the base, not reddish yellow on the basal two-thirds, and
the first joint of tarsi is black, not yellow ; the whole insect
is darker than Walker's type. The female has a short
ovipositor, not including the seventh segmentj though it is
much compressed laterally.
In the Brit. Mus. Coil, a female from Mangalore, Tas-
mania, presented by A. White, has the legs very similar to

JVeottamus gibbonsi, ^ $ , sp. n.
Type (male) in Brit. Mus. Coll., presented by C. Gibbons,
20. 2. 16, from Sydney.
Type (female) from Sydney, and other males and females
from the same place and by the same collector.
Tills species will not belong strictly to this genus, as the
ovipositor of the female, though long, does not include the
sixth or seventh segment ; but, as remarked by the late
Mr. Arthur White in his last paper, species from Australia
placed in this genus are many of them not typical and may
require later to be removed to a new genus peculiar to
Australia.
It is a large species nearly allied to my Neoitaynus hjali-
pennis, but distinguished from it by the ovipositor not in-
cluding the seventh segment, by the moustache being wholly
black, and the base of the hind femora more or less reddisli
yellow.
Length, c? 16-17, ? 18-24 mm.
Male. — Face with a very large tubercle, blackish with pale
tomentum, thickest at the sides. Moustache composed of
many short black bristles. Palpi black, with white hairs.
Bt-ard white. Antennce black, the first two joints and the
forehead with black bristly hairs. Thorax with the usual
stripes very distinct, the middle one not divided and the side
ones continued from the anterior border to the posterior
border ; the prsesutural, supraalar, and postalar bristles each
two in number ; dorso-central bristles numerous, some stout
and some hair-like, with short black hairs continued to anterior
border rather Dysmachus-Vike. Scutellum with at least two
stout black bristles, intermixed with finer hair-like ones
which also cover the dorsum. Abdomen blackish, with some
grey tomentum, and the segmentations grey j^ sides grey ;
the pubescence on dorsum is thick and black, but short, sides
with white hairs. Genitalia long and narrow, longer than
the last two segments together, shining black, with short
black hairs. Legs black, the hind femora reddish at their
extreme base, in some of the specimens this colour is ex-
tended ; the tibise reddish yellow for two-thirds of their
length; fore femora with long black and white hairs above
and below, the others with short black pubescence and black
bristles ; tibiae and tarsi with black bristles. Wings clear,
the small transverse vein almost in the middle of the discal
cell, which is very narrow.
Female identical. The ovipositor, though not including
Asilidas of Australia. 65
the seventh segment, is very long, almost the length o£ the
last four segments.
A male and female from Tasmania seem to belong to this
species ; the male has some white hairs in the moustache.
Neoitamus australis, ^ ? , sp. n.
Type (male) and another, type (female) and another ;
all from Sydney [G. Gibbons).
A small species, distinguished from Neoitamus varius,
Wlk., by the white bristles on thorax and by its lighter
colouring. Legs reddish yellow, with black streaks. Mou-
stache pale yellow.
Length, S 10-11, ? 14 mm.
Male. — Face covered with silky yellow tomentum, tubercle
very small. Moustache composed of long bristle-like yellow
hairs. Antennce blackish brown. Postocular bristles pale.
lliorax covered with yellowish-grey tomentum, the stripes
dark blackish brown, the median one broad, not divided, but
becoming narrower posteriorly. The prsesutural bristles two
in number (one black, one white), one supraalar, one postalar,
both long and white in colour ; dorso-central bristles weak,
white, four in number ; pubescence on dorsum scanty, black ;
a median line of hairs from the anterior border extends
beyond the suture composed of short but distinct hairs.
Scutellum with two long white bristles on its margin.
Abdomen covered with grey tomentum and with a large black
spot on each segment; a long yellowish bristle at the side
of most of the segments, three longer ones between the fourth
and the fifth segments, and yellow hairs intermixed ; pubes-
cence on dorsum short, white. Genitalia large, black, with
black pubescence. Legs long, slender, the coxse black, the
femora reddish yellow on their basal halves with the exception
of the hind pair, which are black at their extreme base ; only
the middle and posterior ones have black bristles, and then
only few in number ; all have some soft hairs below ; tibiae
reddish yellow, black at their apices, the tarsi on their ante-
rior joints reddish, then black ; tibise and tarsi with black
bristles. Wings grey, the small transverse vein beyond the
middle of the discal cell.
Female similar. Ovipositor includes only the seventh
segment, as in Neoitamus varius, which does not include the
sixth as stated by me in the Ann. & Mag. Nat. Hist. (8) xi.
p. 432(1913), and in both species the seventh is only included
in a modified degree.
This species will belong to the late Mr. White's subgenus
6Q On the Asilidge of Australia.
Rhahdotoitamus, formed by him for species of Neoitamus with
the femora striped or partly yellow.
Ommatius distinctus, (J ? , sp. n.
Male (type) in Brit. Mus. Coll. from Townsville, Queens-
land {F. P. Dodd), 1904, 284 ; another in Mr. Gibbons's
Coll. from Eidswold, Queensland ; another from Kuranda,
Queensland [F. P. Dodd), in Mr. Taylor's Coll. ; and a
female (type).
A species distinguished in the male by the dilated wing
and by the brown spot on apex of wing, which is absent in
the female. Moustache black and white. Legs yellowish,
with black stripes.
Length, c? 13-14, ? 13 mm.
Male. — Face with a fairly large tubercle, not, however, very
prominent, covered with whitish tomentum. Moustache
composed of whitish long bristly hairs and two long black
bristles above ; in one male there are four of these. Beard
whitish. Antennae dull brown, the feathered arista twice as
long as the antennoe themselves. Hind part of head with
white bristles and white hairs below. Thorax blackish blue
with grey tomentum ; two prtesutural bristles, one supraalar
bristle, and one postalar bristle, nearly all white; the dorso-
central bristles chiefly white ; the dorsum almost bare of
pubescence. JScuiellum the same colouring, with two white
bristles. Abdomen blackish, with grey tomentum and some
grey hairs ; sides with longer grey hairs. Genitalia rather
stout and prominent, black. Legs yellowish red, with black
stripes on the upper sides of the fore and middle femora, the
hind pair with the apical half only, black above ; the hind
tibiae black at apex; the last four joints of all the tarsi
dusky ; the femora all incrassate, the middle pair with
noticeable black bristles, the hind pair with four or more
white ones, the hind and fore pairs with long fine white hairs
below ; the fore tibise with the same, and the others with
shorter white pubescence; the bristles on the legs almost
entirely black. Wings clear, the anteiior border very much
dilated in the middle, the veins coalescing and forming a
black thick border ; the brown spot is at the extreme apex,
reaching across the anterior branch of the third vein ; tlie
small transverse vein is this side of the middle of the discal
cell.
Female seems identical, but the black bristles on moustache
are more numerous and those on the thorax are largely black,
those on the middle tibias white. Wings at apex are very
faintly grey.

Siid-Afrik. i. p. 126 (I860).]
Priority must be given to Walker's name, as, with the
kind help of Major Austen, I discovered the publication of
206 Miss G. Ricardo on
Loew's paper did not take place till Sept. 27th, 1851,
whereas Walker's paper was published on June 3rd, 1851.
Tiiis latter author gives a very short diagnosis of the genus,
and does not mention the characteristic venation of the wing
— viz., the absence of the ambient vein of wing posteriorly,
and the failure of the veins to reach the hind border, or, if
they do so, they become very fine. Loew gives an ample
description of the genus in his Dipt. Siid-Afrik.
Walker established the genus for two species from East
India, and, as far as I am aware, he does not mention it again
except in the Dipt. Brit. Mus., Suppl. 3 — a mere repetition.
On examining these two species, I find they belong to the
genus Dasytlirix^ Loew (which, as stated above, must give
priority to Walker's genus), and have nothing to do with the
genus Andrenosoma, Rondani. The genus Nusa, Walker,
must be no longer contused with Andrenosoma, to which it
bears no kind of resemblance.
The confusion seems to have originated with Williston,
wlio, in Trans. Amer. Ent. Soc. Philad. xviii. p. 80 (1891),
sinks Nnsa under Andrenosoma, Rondani. V. d. Wulp, in
his Cat. Dipt. S. Asia (1896), places the two species of Nusa
under Rondani's genus, which was founded in 1856, and after
1896 Aldrich and other American authors give iV^wsa priority,
while the late Piofessor Hermann, in his Beitriige Kennt.
siidamerik.. Dipt. Fauna, p. 239 (1912), does the same,
making Nusa cequalis the type of the genus, and alluding
with approval to the figure of it in Ins. iSaundersiana. His
long notes on this genus under the name of Nusa will now
apply to Andrenosoma, which must take the place of Nusa
in Kertesz's Cat., and my species Nusa africana, and queens-
landiaiid tectamus, Walker, will be respectively Andrenosoma
species.
The genus Andrenosoma, Rondani, is richest in species in
the Neotropical and Pala3arctic Regions ; only one species is
mentioned from the Oriental Region, viz., crassipes, Fabr.,
from Sumatra.
The genus Dasythrix, now Nusa, was formed for species
from S. Africa ; a few species are also recorded from Arabia
and S. America, one from 8. Europe, and one from Algeria.

Type of the genus.
It may be distinguished from Nusa formio, Wlk., by the
absence o£ any reddish-yellow or honey-yellow colour on the
legs. Tiie third joint of the antennce is somewhat longer,
the moustache pale yellow. Abdomen black, with white
tomentose spots at sides, not covered apparently with tawny
pubescence and tomentum as in the above-mentioned species.
In both these species the third joint of the antennae is chiefly
reddish or tawny.

Type (male) from North Bengal (Miss Campbell's Coll.).
This small species was described under Asilus by Walker,
who apparently overlooked the peculiar venation and other
particulars ; neither does he mention the sex. This species
has a general resemblance to some of the African species,
and has, like them, the short third joint of antennas.
A black species, with distinct ashy-grey segmentations on
the abdomen, and the scutellum is covered with the same
coloured tomentum.
Length 15 mm.
Male. — F'ace covered with ashy-grey tomentum. Moustache
composed of numerous strong black bristles and a few short
white hairs at sides. Antennce with the two first joints largely
awny and with black bristles ; these latter are very strong
A\ the back of the head. Thorax blackish, with grey
tomentum at sides and on shoulders, the pubescence black.

with stout black bristles at sides. Scutellum bordered with a
thick row of black bristles and a few black hairs intermixed.
Abdomen black ; the pale tomentose segmentations become
wider at the sides, pubescence and the bristles at sides black.
Genitalia rather large, the upper pincers partly tawny,
pubescence black. Legs blackish, the tibise and tarsi reddish
brown, pubescence black, long soft hairs on undersides of
femora and tibise, the tips sometimes inclining to tawny
colour, bristles black and numerous. Wings clear, veins
reddish brown.
Walker, when he created the genus JSusa in 1851, evidently
overlooked the fact that his species here mentioned would
belong to it.

Type (female) from East India.
Three females and four males from Trincomalee, Ceylon
( Yerhury) .
This species is distinguished from Nusa grisea, Hermann,
from Formosa, by the shorter rounder shape of the third
joint of antennae; in N. grisea this joint is distijictly elon-
gated and longer than the first joint, whereas in this species
it is not so long. The honey-yellow colour of the legs in
the Formosan species is here confined to the knees, otherwise
it generally resembles N. grisea. The ovipositor is small,
armed with stout black bristles ; the genitalia of the males is
also rather small, with long narrow upper pincers, the lower
pair shorter. Thoracic and scutellar bristles very stout, the
shorter stout ones on the legs yellowish or whitish. Mous-
tache composed of yellowish-white bristles, with black
bristles on the lower part of the face. In the type and one or
two ef the other specimens two or more stray black bristles
appear in the middle of the moustache.
There are several specimens in the Brit. Mus. Coll. allied
to these three species, but different, not in sufficiently good
preservation and chiefly isolated specimens, so that it is not
advisable to describe them.

Length, ^ 21, ? 22 mm.
Male. — Face covered with ashy-grey tomentum. Mous-
tache composed of black bristles and hairs ; a few short
white hairs above and two longer yellow ones. Palpi and
proboscis with black hairs. Antennce black, the first two
joints with many black bristly hairs, the third joint longer
than the first^ the basal narrow part black, the apical broad-
ened part black at the base only. Ocelligerous tubercle with
two very stout black bristles. Hind part of head with two
very stout ones and smaller ones on each side. Collar black,
covered with yellowish-brown tomentum and with black
bristles and hairs. Thorax black, with two well-marked,
triangular, yellowish-brown, tomentose spots on the shoulders,
which are bordered below with a lighter grey tomentose
band, extending along the sides of tliorax ; a very narrow
stripe the same colour as the shoulders is visible at the suture
proceeding from the sides, distinct in the female, probably
denuded in the male. Dorsum of thorax with fine black
hairs, longer anteriorly and posteriorly, armed at sides with
the usual very stout black bristles. Scutellum the same
colour as thorax, with yellow-brown tomentum, and armed
on posterior border with a row of very stout black bristles.
Abdomen brownish black, with very narrow lighter segmen-
tations and black pubescence, bristles at sides yellow with
pale hairs. Ovipositor black, shining, short, but swollen
with black pubescence. Legs with black pubescence, which
is long and soft on the tibise, the femora with fine pale hairs,
white and thick on the anterior pair, all bristles black.
Underside of the fore and posterior tibiae with a thick short
brush of golden-yellow hairs. Wings dusky, the fii'st and
fourth cell closed as usual, the veins not so attenuated as in
some species ; the veinlet from the dorsal cell is so, and does
not reach the border; some pale streaks are visible on the
basal part of wings.
Female identical, but hairs below proboscis white, soft, and
long. Palpi with white pubescence. Tbird joint of antenme
duskier. Legs more heavily armed with bristles, especially
the anterior tibise and tarsi. Abdomen stouter. Ovipositor
very short.

210 Miss G. Ricardo on
Another male from Yoouzalein Vallej, Burma, April 1891
(^Col. Bwghain).
A species at once distinguished by the pale ashy-white
tomentum on the first three segments of the black abdomen.
Moustache pale yellow. Legs black.
Length, type 22, second male 18 ram.
Face protuberant as in all the species here mentioned,
covered with ashy-grey tomentum. Moustache composed of
yellowish-white long soft liairs. Antennce witli reddish
bristly hairs on the lower sides of the first two joints, the
third joint elongated, nearly as long as the first two together.
Bristles on ocelligerous tubercle and posterior part of head
stout, black. Collar brownish black, with black bristles in
the centre and white hairs at sides. Thorax brownish black,
with some grey tomentum ; two dark median stripes ara
visible ; pubescence on dorsum thick, black, short, but longer
posteriorly, the ashy-grey tomentose shoulders with short
black hairs ; the stout black bristles at sides and posteriorly
are numerous. Scutellum the same colour as the thorax, but
the pale ashy-white colour of abdomen is visible on the
anterior half of scutellum. Abdomen blackish, the pale
segments with white pubescence ; this pale colour is continu'^d
on the sides of the segments, reaching in a narrow line to
the centre of the fourth segment ; pubescence on the dark
parts black, white at the sides of abdomen. Genitalia rather
large, black and shining, with black pubescence. Legs
black, with white pubescence and yellow bristles. Wings
clear, veins not strikingly attenuated.
Andrenosoma, Rondani.
Subgenus Pogonosoma, Rondani.
Founded by Rondani in 1856 for species with three sub-
marginal cells ; but, as v. d. Wulp and Hermann point out, this
is hardly a good enough character to divide it from Andreno-
soma^ Rondani, some specimens having been found with the
dividing vein which separates the first submarginal cell into
two absent in one wing and present in the other. Hermann
states if it is retained it should be looked upon as a subgenus
of Andrenosoma {Nusa).
The subgenus seems widely distributed in the Oriental
Region (where there are eight species), the Palaearctic and
Nearctic Regions (both represented by four species each).
Rondani made Laphria maroccanum, Fabr., the type of
the genus.
the Two Genera Nusa and Pogonosoma. 211
Pogonosoma fusifera, $ , Walker.
Proc. Linn. Soc. Lond. i. p. 12 (1856) {Laphria) ; t. d. Wulp, Col.
Dipt. S. Asia, p. 89 (1896) {Andrenosoma).
[Pogonosoma analis, de Meijere, Tijd. Ent., Suppl. Ivi. p. 53 (1913).]
This species (a female from Singapore) was correctly-
placed in Andrenosoma, but, having the three submarginal
cells, it falls into this subgenus.
De Meijere's species (a male from Java and a female from
Sumatra) is evidently identical with it, from the description.
In Walker's type, measuring about 15 mm., the first posterior
cell is almost closed on one wing and narrowly open on the
other, as in de Meijere's types, which measure 18 mm.
There is a much damaged specimen measuring 25 mm.
from Siam (presented by H.R.H. Prince of Champon) in the
Brit. Mus. Coll., probably a male, having the last segments
of the abdomen foxy red, with the same coloured pubescence
as described by de Meijere.
The female has these last segments blackish, but covered
with the foxy-red pubescence. Prof, de Meijere considers
Pogonosoma beccarii, Rondani, from Borneo, also with a red
apex to abdomen, as distinct from his species,
Pogonosoma cedrusa, ? , sp. n.
This specimen was sent me for identification in January
1924 by Dr. C. F. C. Beeson at Dehra Dun, stating that it
had been bred from wood. He kindly gave me permission
to keep it for the National Collection, No species of this
subgenus has as yet been described from India, though
Pogonosoma fusifera, Walk., is from Singapore, and Pogono-
soma funehris, Hermann, is from Formosa (a co-type of this
species is in the Brit. Mus. Coll.), and is distinguished from
this Indian species by the dull black colouring of abdomen,
the incrassate femora, and the darker wings.
Pogonosoma semtfusca, v. d. Wulp, must be nearly allied
to this new species, which is distinguished from it by the
brighter blue metallic colouring of the abdomen, the simple
hind femora, the shorter ovipositor, and the less well-defined
colouring of the wings.
Type (female) from Fagu, 8000 ft., Simla Hills, 8. iv. 1922
(C. F. C. Beeson). Bred from Cedrus deodara.
A medium-sized species, with purple bluish shining metallic
abdomen. Face with black bristles and white hairs. Legs

nearly the same colour as the abdomen, with white pubes-
cence. Wings tinged brown.
Length 19 mm.
Face blackish brown, the tubercle large, covered with
stout black bristles, forming the moustache, a few fine white
hairs intermixed. Cheeks with long fine white hairs, a few
shorter black ones on each side below the antennae. Palpi
with black liairs. Beard white. Hind part of head with
bristly black hairs, becoming weaker and reaciiing round to
the proboscis. On the ocelligerous tubercle two weak black
bristles. Antennce with the first two joints blackish brown
and with stout black bristles (third broken off). Thorax
dull blue, with brighter metallic glittering patches on the
sides, devoid of the brownish-yellow tomentum on dorsum,
which is nearly bare of pubescence anteriorly, but the sides
have long soft black hairs disposed in groups ; prealar bristles
stout, three in number, postalar two in number. Posterior
part of dorsum with rather numerous weak black hairs, and
the tomentum here is whitish. Scutellum dark blue, some-
what shining, with no bristles (denuded) ; on the specimen
from Khasi Hills there are two weak black ones. Abdomen
almost devoid of pubescence, sides of anterior segments with
long white hairs ; on the posterior segments shorter black
hairs predominate ; on each segment one or more stout black
bristles are present on the sides, and the second, third, and
fourth have small triangular white tomentose spots. Ovi-
positor short, no longer than the last segment. Legs dull
bluish, but the anterior pair are more brownish than blue,
and the same is the case with the middle pair ; pubescence
long, white, thickest on the tibiae ;. on the femora it is black
above and intermixed with white hairs below ; the tarsi with
black hairs and bristles ; there are numerous long black
bristles on the tibise and one or more stout ones on the hind
femora towards the apices ; the underside of tibiee with thick
brush-like foxy-red hairs. Wings tinged brown, paler at the
extreme base, with clear white spots in all the cells on the
posterior border except the apical one, and including the
fourth posterior cell : the first posterior cell is widely open,
the brown colouring is more intense on the anterior border in
the centre. Halteres pale.
A very much damaged specimen from Khasi Hills, India
[F. W. L. Sladen), seems identical with the type ; it is also
a female. A female from Trincomalee, Ceylon, is very nearly
allied to these, but appears somewhat different.
