6. JEDES OBSCURUS, Meig. (M. S.). 



In the collection of the Jardin des Plantes, I found a specimen, 

 labelled as above, in Meigen's handwriting. It has the hind 

 borders of the segments distinctly darker than in front, but 

 cannot be said to be banded. 



My notes on the venation of the wing, as roughly made out with a 

 hand lens from a specimen I did not care to handle too curiously, corre- 

 spond sufficiently well with Mr. Theobald's notes on ^. cinereus, with 

 which I am inclined to thmk it must be identical. No such name is 

 traceable in Meigen's works, and possibly the specimen was so labelled 

 by him, before he had finallj^ made up his mind how to call his new 

 species, though it must be admitted that the name obscurus is much the 

 more appropriate of the two. 



7. iEDES RUFUS, Gimmerthal (" F. E." p. 300). 



Is said to be redder than y^. cinereus, and to have three 

 darker lines on the testaceous thorax. 



Probably identical with the above, and in any case inadequately 

 described.
