10. GABIANUS. 21)7 



On the wing L. leucopterus has a much more buoyant flight 

 than L. (jlaacus, and tho length of wing in proportion to its com- 

 I)aiatively small bulk is very noticeable; but prepared and over- 

 stuffed skins sometimes offer difficulties. Still, in spite of its longer 

 wing in proportion to its bulk, the largest male L. leucopterus does not 

 attain to the length of wing found in the smallest female L. glaucus.
