This species we are unable to recognize in our material ; the ref- 

 erence to inscripta raises the suspicion that the geniculata from 

 Greenland may be this species, and this may really be identical with 

 inscripta. On this we have no evidence. 



Mr. Fyles has reported lutea from Quebec.

This species is not among those we have examined. It has, how- 

 ever, been seen from the Commander Islands, Alaska, by Coquillett, 

 and is also reported from New Jersey by Johnson in Smith's Cata- 

 logue of the Insects of New Jersey.

 fiavescentes." 



Length 8 mm. This species, lacking the antenna-, may belong to a different 

 section, but it shows most of the characters of a Sicatophaga.
