PREFACE.

The second volume of Diptera of " Insecta Britaiinica " com-
prises the latter part of the Brachycera, with the Hyjjocera and
the Eproboscidea. In the Brachycera two families are described,
the Muscida and the (Estrida, and the former is divided into
sixteen subfamihes. Upon closely examining the little-studied
families contained in this volume,, the number of species has been
found very much greater than was anticipated, and, as we are
limited to a certain number of pages, only a portion of the
species could be given. The British Diptera seem to be as
numerous as those of Scandinavia, which Zetterstedt, in his ela-
borate work, occupied eleven volumes in describing. The sub-
families above mentioned are here briefly noticed. The Myopides
aud the Sarcophagides are mostly described. In the Tackinides about
half the British species of Tachina are omitted. The species of
this genus are very numerous, aud require all their characters to
be fully detailed, in order to identify them with certainty, and the
omission of a precise notice of a single part of the structure is
sufficient to cause a doubt as to the species. The greater part of
the Muscides, and about half the Besides are described ; but the
Anthomyides in this volume probably do not exceed one-fourth of
the British species. Many species of Helomyzides, Lauxanides,

IV PREFACE.

Ortalides, Oscinides and PsiUdes are unnoticed ; but the Sepsides
omitted are for the most part mere varieties. The Borhorides
and the Hydromyzides are more complete^ and are copied from
Mr. Hahday's excellent descriptions of the genera and species of
those tribes. The Geomyzides and the Ph'ytomyzides are mostly
passed over ; but the (Estrida, the liypocera, and the Bp-ohoscidea
are rather fully detailed. Mr. Westwood has again prepared ten
plates for this volume, Mr. Haliday's state of health having
prevented his contributing the illustrations of the wing-veins of
Diptera.

Head large ; proboscis distinct ; eyes below bounded by the cheeks ;

last joints of antennae forming a slender arista, attached to the third

joint on its upper edge. Wings perfect, very rarely abortive ; cubital

vein simple ; brachial veins without spurious vein ; axillary lobe

rounded. Halteres of some hidden, of others uncovered.

The Muscida are the most remarkable of the families oiDijitei'a,
on account of their very numerous groups, species, and individuals,
of their extensive variation of structure, and of their great import-
ance in the economy of nature. The nomenchiture of some parts
of their structure requires a short explanation. ^\^\\Qjrons extends
from the hind part of the head to the base of the antennae, and
occupies the space between the eyes ; its hinder part is the vertex,
before which are the ocelli ; its fore part contains the, frontalia,
which are dark -coloured, and more or less linear; in some cases

MUSCID^,

they are partly or wlioUy divided by the triangular interfrontalia.
The 23tiUmim is a soft membrane, which in many species, and espe-
cially in the newly-hatched flies, appears between the antennae
and the front, and is alternately projected and withdrawn. The
fades extends from the base of the antennre to the epistoma ; its
middle part contains two fovea, in which the antennse rest ; its
lateral borders are the facialia, and are frequently setigerous.
The mecUana are two triangular parts between the facialia and the
optica, or borders of the eyes, a little above the lateral borders of
the peristoma. The lateralla are beyond tliera, and on the lower
sides of the peristoma. The third joint of the antennae attains
its maximum of development in the leading groups of this family,
and may be the organ of smell; it is perforated on its inner side
in the larger TacJnnides. The fourth, fifth, and sixth joints form
the arista, or bristle ; the fourth and fifth are obsolete in most
genera. In the wings the flexure of the prajbrachial vein is gene-
rally a characteristic of the TacMnides and of the Miiscides which
have the most powerful flight. The radial vein springs from the
mediastinal vein, near the humeral transverse vein. The cubital
vein springs from the radial near its base, and is connected with
the prsebrachial before one-third of its length by a thick slightly
oblique transverse vein. The pobrachial vein springs like the
pra^brachial and the anal from the intermediate axis, near which
it is connected with them by two transverse veins. The distance
of the discal transverse vein from the border is measured on the
continuation of the pobrachial vein. The anal vein is almost
obsolete soon after its junction with the pobrachial. The subanal
vein springs from the intermediate axis.

Some species are insectivorous, many are parasitic in the larva
state, the rest feed on living or decaying animal or vegetable
matter. The species will form two divisions : —

Alulae distinct 1. CALYPTERiE.

Alulae indistinct or none 3. Acalypter^.

Alulce distincta.—Div. 1. CALYPTER^E.

The Calypterce are generally also distinguished by their comparatively
large size, compact bodies, dark or mctaUic bodies, and fretjucntly by
the development of the fourth and tifth joints of the antennae or the
basal joints of the arista.

border ; radial vein ending at about two-thirds of the length of the
fore border ; cubital vein undulating, ending at a little in front of the
tip of the wing; praabrachial vein forming an obtuse angle at its junc-
tion with the discal transverse vein, joining the costal vein at very little
in front of the tip of the latter; discal transverse vein straight, its dis-
tance from the hind border one-fourth or one-half of its own length ;
axillary and subaxillary veins united at some distance from the border ;
anal vein not reaching the border. Alulce small. Abdomen cylindrical,
recurved beneath at the tip. Legs stout.

The species are probably parasites of other insects. The two

The form of the body, of the antennae, and of the veins of the
wings, in this subfamily, is very variable ; the prfebrachial vein is
abbreviated in a few species, but in all the rest it forms a flexure,
as in the three following subfamilies. With a few exceptions the
individuals are scarce and the species numerous, but the reverse
of this rule is more characteristic of the Mitscides. Their highly-
developed structure and their rapid flight at once distinguish them
from all the following groups. They may be divided into the fol-
lowing genera : —

a. Abdomen depressed. Phasia.
a a. Abdomen not depressed.

b. Abdomen arched, recurved beneath at the tip.

c. Praibrachial vein joining the cubital before its tip. Ocyptera.
c c. Prajbrachicil vein joining llie costal. Piiania.
b b. Abdomen not arched nor recurved.

PHASIA.

c. Abdomen globose. Gymnosoma.
c c. Abdomen not globose.

distinctions rather than as characters of genera, for which they
have been used by Desvoidy, Macquart, and Meigen. The species
may be grouped thus : —

mediocres.

Body hairy, bristly. Head not vesiculose. Tovefe of the face very
shallow. Antennse nearly reaching the epistoma ; third joint very
slightly tapering from the base to the rounded tip, more than twice the
length of the second ; fourth obsolete ; fifth short ; sixth short at the
base, much longer tlian the third. Thorax nearly elliptical, with a
transverse suture. Wings of moderate size. Costal vein ending where
the prsebrachial meets it on the hind border at some distance from the
tip of the wing ; subcostal vein ending at very little beyond one-third
of the leugth of the wing ; mediastinal vein ending at about half the
length ; radial ending at beyond sixth-sevenths of the length ; cubital
vein joining the costal at very little in front of the tip of the wing ;
prabracJual vein straigJit, or nearly so. Anal and subanal veins abbre-
viated. Alula of moderate size, or small. Abdomen not long. Legs
of moderate length.

The Anthomyides are nearly allied to the Muscides, but may be
distinguished by the straight praebrachial vein, and by the smaller
alulae. Their size also is generally smaller, their bodies longer
and less compact, and their flight less powerful. Their larvae mostly
live on decaying vegetable substances. The three genera here
adopted may be thus distinguished : —

The Scatophagy generally prey on other Blptera. "The eggs
of S. stereoraria are deposited in dung, and if not thus sur-
rounded with moisture, they shrivel up and come to nothing.
But it is equally necessary that they sliould not be wholly covered ;
if they were, the young larva would be suffocated on emerging
from the egg. Each egg is provided at its upper end, at which
the animal when hatched comes out, with two diverging horns;
these prevent it being stuck more than three-fourths of its length
in the dung, in which the female deposits the eggs one by one."
