Note. — Stein's description of the species, Berl. Ent. Zeitsch., xLii, 239, 

 turned out to be based on specimens of what he afterwards called afUnis 

 (loc. cit, p. 286). The latter species had been to some extent distributed 

 among American collections by Mr. Coquillett, under the name of vicina.

Note. — There is much difiference of opinion as to the essential charac- 

 ters which distinguish this from Coenosia; some good authorities do not 

 regard it as distinct. Until the species have been adequately studied with 

 reference to the decisive points, it seems hardly possible to avoid con- 

 fusion.
