r DIPTERA. 313 
Drioprsis, 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 antennz 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 
describes five of them, calls it apicalis, 
CrepHatia, Meig. 
Where the palette of the antenne is narrow, elongated, and al- 
most linear, with a pubescent seta; the fore-part of the head is con- 
siderably prolonged and without sete; the palpi are strongly dilated 
in the manner of a spatula(1). 
Sepsis, Fall. Meig.—Zephritis, Fab.—Micropeza, 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. cynipseas Musca cynipsea, L. Very small; cupreous- 
black and glossy; head black; coxz and anterior legs fulvous; 
a black point near the extremity of the wings. It diffuses a 
strong odour of Balm and is found in great numbers on leaves 
and flowers; its wings are constantly but slowly vibrating(2). 
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 or
