Observation. Scaeva dn/arlis Holmgren, Ins. Spetsb. 26. 

 Spitsbergen and Greenland (Holmgr. his. Nordgroenl. 100). Not 

 having seen the description of this species, I cannot tell whether 

 it is a true Syrplms, a Plat >/clii nix, or a Milanostoma. 



Scaeva arcuata Fallen, which Holmgren, Ins. Nordgroenl, has 

 from Greenland, belongs to what 1 call the group of Syrphus 

 Lapponicus; for this reason I have not quoted it in the above list. 



St/i-plnis sessmaculatus Palisot-Beauvois, Ins. 224, Dipt. Tab. Ill, 

 Southern States, San Domingo. This specks evidently 

 belongs to some other genus than Syrphus. The author compares 

 it to Syrphus tympanitis Fabr. and says that it may be a mere 

 variety, or the other sex of that species. Si/rplius tympanitis 

 Fabr. Syst. Antl. 226, 10, is, I think, a Volucella.
