42 THE ENTOMOLOGIST. 
“Of the three areas into which Latreille divides the wing 
(exclusive of the extreme basilar area), the costal ends with 
the cubital vein, or its hindmost branch, if branched. The 
intermediate extends back from this to the anal vein, and the 
internal occupies the rest behind the anal vein. ‘The first of 
these areas becomes very narrow in those Nemocera which 
lead to Cecidomyia, and recedes more and more from the tip 
of the wing, not the mediastinal alone, but the subcostal vein 
often disappearing. In other cases, and generally where the 
veining of the wing is most fully developed (Tabanide, 
Asilidz), the costal area takes in the whole tip of the wing, 
though sometimes the intermediate area expands itself by the 
curvature of veins as it reaches the margin (so in Midas, &c.). 
The tip of the wing, therefore, may be considered as the 
medium point of limit at the margin between the costal and 
intermediate areas. When the costal vein vanishes without 
being continued round the posterior margin, it most com- 
monly ends at the end of the subapical vein.”
