Cited but not identified. 



Male. — Front as wide as ocellar triangle, quite black near vertex, 

 gradually covered with white pollen below, with numerous small 

 white hairs which continue close to the eye as far down as the middle 

 of the third antennal joint ; bucca two-fifths the eye height, translu- 

 cent yellow and shining except before and behind; back of head 

 black to the proboscis; antennae, palpi, proboscis and facial struc- 

 ture as in '??iaceUaria, except that the vibrissae are a little nearer the 

 epistoma. Pleurae black. Hind ealypter brown on disk with white 

 rim, a few pale hairs in the concavity close to base. Postalar decliv- 

 ity with tuft of long hairs on its center as in macellai'ia (above base 

 of front ealypter). Genitalia on same plan as in macellaria but the 

 inner and outer forceps notably longer, and the former more slender ; 

 the penis at apex also more drawn out. Legs entirely black. Wings 

 as in macellaria. 



Female. — Front 0.31 of head width (average of three, 0.29, 0.30 

 and 0.33) ; parafrontals shining black above almost to middle; back 

 of head yellow below changing abruptly to black just below neck. 

 Fifth abdominal segment conical, polished, metallic. Otherwise as 

 in male. 



Length 5.5 to 7 mm., averaging distinctly smaller than macellaria. 



Redescribed from one male and three females, Key West, Florida, 

 January 31, February 1 and C, 1869 (labels in handwriting; collector 

 doubtful, perhaps Burgess) ; one female evidently collected many 

 years ago with only the label " Fla." In addition to this old mate- 

 rial, the United States National Museum has lately received 65 speci- 

 mens of both sexes in alcohol (now pinned) from Dr. Paul Bartsch, 

 curator of moUusks, United States National Museum, which he col- 

 lected at one time on San Salvador Island, Bahamas, in the summer 

 of 1923, on dead moUusks. 



One Key West female bears the label " Chrysomyia certima AVlk.," 

 in Coquillett's handwriting. This would appear from Walker's 

 description to be a mistake, as certima is quite certainly a synonym
