Platypezidae—A small family which, like the preceding 
one, has a venation all its own. Though I set up two new species 
of Platypeza I have since come to the conclusion that they are

at a later date. A second revision by me in 1912 with ten

are reserved for my Fauna volume. 
Syrphidae.—This very extensive and beautiful family is

found any author’s tables more difficult to follow than Brauer’s, 
except perhaps those of Brauer and Bergenstamm together.
