The Dung-flies, Scatophaga (Sca-toph'a-ga), are rather 
in, 
slender flies, which have the 
hair, and which arc com- 
mon, especially about 
fresh cow-dung. They 
belong to the Subfamily 
Cordylurinee (Cor-dyl-u- 
ri'nse). 
To the subfamilies Or- 
talinee (Or-ta-li'nse) and 
Trypctinee (Try-p e-1 i' n ae) 
belong many common 
species which have the 
wings beautifully marked 
with dark spots or bands. 
In the Ortalinae vein II 
extends to the margin of 
the wing in the usual 
way; in the Trypetinas 
the outer part of vein II 
turns suddenly towards 
the margin of the wing, 
and at the same time 
becomes much less dis- 
yellowish
