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 (Tabanidae, 

 Asilidae), 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."
