with the exception of ^. viridis, Eversm., and M mixta, Latr., and 

 this last named is not rare in the district and is on the wing during 

 September, it is not probable that Miiller has overlooked it, but on 

 the contrary has had the species before him when he described 

 AS. squamata, which name I propose instead of Latreille's. 



There are a few other species in Miiller's work, but of these 

 I can at present say nothing definite, but as evidence of the extent 

 of Miiller's knowledge of the Danish Odonata I append a list of the 

 species of LlbellnJidernes and ^•ichnidernes groups that he has 

 mentioned in his papers and which w'e have been able to recognise.
