(^. Shining black. Front with two bristles on each side below 

 the vertical ones ; ocelli with small proclinate bristles. Face rather 

 flat, wholly opaque light grey ; a transverse groove above the oral 

 margin. Antennas black, third joint oval, fully twice as long as 

 wide ; arista moderately long plumose on the upper side, pubescent 

 on the under side. Thorax and scutellum wholly shining, without 

 stripes or spots. Abdomen shining brownish-black. Legs black 

 or brownish-black, the four posterior tibife and tarsi more or less 

 yellow. Wings hyaline, the penultimate section of the fourth 

 vein about one-half the length of the ultimate section. Length 

 5 mm. 



One specimen. St. Vincent. This species is allied to 

 S. longijjennis, bnt is distinct in the more shining colour 

 and in the distinctly narrower front, which is perceptibly 

 longer than wide. Possibly it is identical with Laiiccania 

 muscaria, Loew (Centur., i., 87; Schiner, Reise der 

 Novara, Dipt., 282), but the face is not shining. As the 

 shining black colour is the final difierence between Sapro- 

 myza and LaiixcDua, this species would pi-operly come 

 under the latter. The difference from S. longipennis is, 

 howevei', very slight.
