anterior legs from the others, is more apparent here than in the fol- 
lowing subgenus.

Blackish; abdominal annuli margined above with whitish; legs 
fulvous, with a black ring round the posterior thighs. In the 
woods about Paris. To this species M. Meigen refers the Musca 
corrigiolata of Linnzus, which is also a Fabrician Calobata(1).

Or my Micropeza, the head is spheroidal, and the last joint of the 
antenne, more elongated than in the preceding subgenus, is almost 
triangular and rounded at the end; the seta is frequently plumous(2). 
Our seventh division of the Muscides, that of the Carrpomyza, so 
called because the larve of several species feed on fruits and seeds, 
in the germ of which the mother had deposited her eggs, is charac- 
terized as follows: wings turned up or distant when at rest, and 
susceptible in that state of a reiterated vibratile motion, or of being 
alternately raised and depressed, and spotted or dotted with black 
or yellowish; a port generally analogous to that of the common Fly; 
but the s are always distant, and the halteres exposed; the abdo- 
men exhibits from four to five rings exteriorly, and frequently termi- 
nates, in the females, in a hard, cylindrical, or conical point, which 
acts as an ovipositors the antenne are always short, en palette, and 
their seta is rarely pilose. 
Several species approach those of the last subgenera in the nar- 
row and elongated form of their body, the length of their legs, their 
head more globular or elongated than in the other Carpomyze, 
where its form is hemispherical. These elongated species constitute 
three subgenera(3). 
(1) Lat., Ibid., 352; Meig., Dipt. According to the figure, given by M. Wie- 
demann, of a species of Werius (fuscus, Anal. Entom., 1), Fab., these Insects must 
have a general resemblance to the Micropezz, but are removed from them by 
their antenna, almost as long as the head, of which the second joint is at least as long 
as the third; the latter is almost orbicular, a little longer than it is wide. It is 
evident then, that this genus is connected with Tetanocera, just as the Calobate of 
Meigen lead to Sepsis, which I had united to the preceding ones under the com- 
mon name of Micropeza. Here the wings are vibratile, which leads us to the 
Cephalia, Ortalis and T'rypeta of Meigen, that present the same characters.

(S) According to Meigen, two of these subgenera, Cephalia and Sepsis, have 
but four apparent abdominal annuli, whilst the following subgenera, Platysoma 
excepted, exhibit five.
