CYHTONEUKA STABULANS. 89 



und jaws more developed. Head bluck , covered by a whi- 

 tish dust , the cheeks and orbits white. Antennae distinctly 

 shorter than the face, black with grayish dust; arista long, 

 thickened at the basal half and plumose along two thirds of 

 its length. Proboscis and palpi black. Thorax, scutellum 

 and abdomen steel-blue; on the thorax five whitish longi- 

 tudinal stripes , which are almost effaced behind the suture ; 

 on both sides of the two first segments of the abdomen a 

 whitish dust. Legs black , the femora more or less steel- 

 blue. Calyptrae darkbrown , with a white margin. Wings 

 hyaline with a grayish tinge ; nervation similar to that of 

 C. erythrocephala] the apical cell however being wider 

 open and the medial cross-vein a little nearer to the base 

 of the wing, before the middle of the discal cell. 



A 9 from Chili in the Leyden Museum ; it has been re- 

 ceived from Dr. C- A. Dohrn , under the name of C. pha- 

 coptera Ph. ; however as far as I know , the species is as 

 yet nowhere described.

A female specimen from Chili (Dohrn); it resembles in 

 all respects our european individuals ; only the discal cross- 

 vein seems to be straighter. 



According to Macquart and Blanchard, C. vicina differs 

 from C. stahulans merely by the absence of the black dor- 

 sal stripe on the abdomen ; but this stripe is not always 

 visible in the european specimens ; it is probably for this 

 reason that Schiner makes no mention of it in his elabo- 

 rate description. Upon such a vague distinction a separate 

 species cannot be admitted.
