INTRODUCTION.

The principal object of the present Catalogue has been to
give a complete Ust of the specimens of Dipterous Insects
contained in the collection of the British Museum, indicating
at the same time the pecuUarities of each, as regards variations
of character, locality, and the source from whence it has been
derived. With this view, the different individuals of each
species contained in the collection are indicated by the letters
a, b, c, &c., following the name of the species and its syno-
nymes, and the description, if it appeared to have been before
midescribed.

The Catalogue of Dipterous Insects has been prepared and
the new species described by Mr. Feancis Walkek, F.L.S.,
so well known for his attention to this order of Insects.

This part contains a revision of the family Acroceridce and
part of the family AsilidcB, with a description of the species
added since the former parts were printed.

Mediastinal vein ending at a little before two-thirds of the length
of the wing. Subcostal ending at beyond seven-eighths of the length.
Radial and cubital springing from a common petiole, which pro-
ceeds from the subcostal at about one-fourth of ihe length of the
wing, and is less than one-sixth of their length. Cubital forked a
little before two-thirds of its length, joined by a veinlet with the
first externo-niedial a little before one-third of its length. P'irst
and third extcvno-raedial springing from a common petiole at much
before half the length of the wing, united again by a veinlet whose
angle emits the second externo-medial. Third externo-medial ex-

hindward, and joinin(T the fourth extemo-medial near the tip of ilie
hitter. Fourth externo-medial and subanal springing from a com-
mon petiole at about half ihc length of the wing ; fourth extemo-
medial forming near its base an angle, where it is united by a vein-
let with the third externo-medial ; subanal ending close to the tip
of the anal. Discal areolet narrow, very long, nearly triangular,
widening from the base to the tip. The wing-veins of the species of
this genus are subject to great variation. The forks of the cubital
vein diverge more or less from each other, and the fore branch is
more or less straight or curved or angular, and in some cases emits
the stump of a vein from its angle. The first externo-medial is
generally parallel to the hind1)ranch of the cubital, but in some spe-
cies is united with it. The second externo-medial very generally
springs from a veinlet between the first and the third externo-
medial, but in one species appears as the fork of the first externo-
medial. The third externo-medial generally proceeds straight to the
border, but is often inclined to the fourth, and in some species joins
the latter on the border, or at some distance from it. The subanal
usually joins the anal on the border ; in a few species it is separate
from it, or is united to it at a distance from the border. In one
species there is a veinlet between the first and second extemo-
medial veins, and thereby an additional areolet is fonned in front of
the discal areolet.
