314 INSECTA. 
slightly inclined, so that the antennz, when viewed in profile, ap- 
pear 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. 
Orrauis, Fall.— Scatophaga, Tephritis, Dictya, Fab.—Tephritis, Lat. 
Where the abdomen is not terminated in the females by an always 
external prolongation, in the form of a tail or stilet, serving as an 
ovipositor(1). 
The body of several species is somewhat more elongated than 
in the following subgenus, and these Diptera, in this respect, are 
intermediate between the latter and the preceding ones. 
The palette of the antenne is sometimes long and linear as in the 
O. paludum, Fall.; and sometimes short and wide as in the O. vi- 
brans—Musca vibrans, Lin.—De Geer, Insect., VI, 1, 19, 20, the 
body of which is black, and the head red, with a white streak on 
the inner margin of each eye; a black spot may be observed at the 
extremity of the wings, and the first exterior nervure of their base 
becomes thickened where it unites with the edge, presenting the 
appearance of a black stigma. 
To this subgenus M. Fallen refers the Musca cerasi, L., or the 
one whose larva feeds more particularly on the red and white-heart 
cherry; when about to become a pupa, it leaves the fruit and enters 
the ground where its metamorphosis is completed. The perfect In- 
sect is very black and glossy, with four transverse blackish bands 
on the wings united by pairs in opposite directions(2). 
Teranops, Meig. 
Where the abdomen of the females terminates by an always pro- 
jecting, tubular oviduct, resembling a tail; the head seen from above 
appears to be almost triangular, and as long as it is wide(3). 
(1) According to Meigen the hypostoma is arched or rather carinated in the 
middle, whilst it is plane in Trypeta. But this carina, although smaller, appears 
to me to exist in several species of the last genus. 
(2) See Meigen. 
(S) Idem. A subgenus approximating to those of the Dolichocera in the pyra- 
midal form of the head, and to the Tephrites in their other characters, particu- 
larly in the abdomen which is terminated in a truncated tube.
