DIPTERA, 377 
an ovipositor ; the antenne are always short, en palette, and their seta 
is rarely pilose. ; 
Several species approach those of the last subgenera in the narrow 
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 these 
subgenera*, 
Diopsis, Lin., Fab., 
Also called Mouches @ lunettes, on account of their eyes being 
placed at the extremity of two lateral, distant, and cylindrical pro- 
longations of the head; the attenne are inserted beneath. The scu- 
tellum is terminated by two spines. These singular Diptera, of 
which M. Dalman has given us a good Monograph—Anal. Entom. 
I—are foreign to Europe. 
But few species are known; one of them is red with a black 
thorax, and a spot of the latter colour at the extremity of the 
Wings; it is found in Guinea and Senegal. I have received a 
specimen of this species from the liberality of my friend Count 
Tousselin, who obtained it from Senegal. M. Dalman, who de- 
scribes five of them, calls it apicalis. 
Crepnauia, Meigq., 
Where the paletie of the antenne is narrow, elongated, and almost 
linear, with a pubescent seta; the fore-part of the head is considera- 
bly prolonged and without sete; the palpi are strongly dilated in the 
manner of a spatula f. 
Sepsis, Fall., Meig. —'Teruritis, Fab.—Microreza, Lat., 
Where that palette is much shorter and semi-elliptical, and has a 
simple seta; the anterior part of the head projects but little and is 
covered with sete; the palpi are almost filiform, and simply and 
gradually increase in thickness. 
S. cynipsea; Musca cynipsea, Ll. Very small; cupreous- 
black and glossy; head black; coxee and anterior legs fulvous; 
a black point ne 'r the extremity of the wings. It diffuses a strong 
odour of Balm, and is found in great numbers on leaves ani 
flowers; its wings are constantly but slowly vibratingt. 
The other Capromyze have the port of common flies, a short 
hemispherical head, triangular or conical abdomen, and moderate 
legs. 
Sometimes the superior plane of the head is almost horizontal cr 
slightly inclined, so that the attenn, when viewed in profile, appear 
to be inserted almost on a level with that plane, or near the front. 
The palpi and the proboscis are retracted within the oral cavity. The 
wings are turned up when at rest, and the abdomen exhibits five 
annuli exteriorly. 
* According to Meigen, two of these subgenera, Cephalia and Sepsis, have but four 
apparent abdominal annuli, whilst the following subgenera, Platysoma excepted, ex- 
hibit five.
