The three black stripes evidently refer to the facial stripe 

 and cheeks. 



It seems therefore evident that badia, on page 559, should 

 be used instead of intersistens on page 615. In regard to the 

 genus, as I pointed out in Psyche (Vol. XVIII, p. 73, 1911) 

 Blcra Billberg 1820 (Type Musca fallax Linne), antedates 

 Criorhina Meigen, 1822 (Type Syrphus asilicus Fallen). At 

 the time, I advanced this name chiefly to offset Penthesilia 

 Meigen, 1800 (no species mentioned). On the other hand, 

 recognizing Criorhina to include only the large pilose species 

 as is done by European authors and by Williston in his synop- 

 sis of the North American Syrphidae, then Cynorhina Will, 

 becomes a synonym of Blera. In any event I cannot see how 

 we can ignore Blera as the author's intention is very clear.
