Explanation of Plate 3. 



The figures are drawn to practically the same scale of magnification, the 

 camera lucida being used. The enlargement is about twenty diameters. 

 As but four of the exotic species (connexa Meig., incompleta Beck., ornatipes 

 Beck., and punctijera Beck.) have been figured, I have included drawings of 

 the wings of those European species I possess.
